"He...he actually has this ability?" Xu Xiaoya couldn't believe it. After all, she had been classmates with Zhao Qiang for more than three years. Xu Xiaoya thought she knew him very well before, but now she felt that Zhao Qiang was a complete stranger.
Luo Xiaowei didn't have so many thoughts. She just nervously clutched her chest, barely daring to breathe loudly. She had only one thought in her mind: I must rescue my father safely. It all depends on you, Zhao Qiang.
"Damn it," a man in his forties cursed, "This kid's trained, huh? He's incredibly agile. If he saves the eldest son of the Haifeng Group and his daughter offers herself to him, he'll hit the jackpot."
Someone mocked the man, saying, "If you're so capable, go down and save them. You'll be the one who benefits."
The man glanced at Luo Xiaowei. He had already recognized her as one of the most eye-catching female protagonists at the previous banquet. Even though her face and legs were covered in soot, she would still be a beauty after washing. However... hehe, the man said, "Forget it. I want to live a few more years. With my figure and skills, I'm guaranteed to fall straight to the bottom with one jump. Don't embarrass yourself."
"Hahaha," the middle-aged man's words drew laughter from the other survivors. In fact, all of them wanted to be heroes, but they simply didn't have the courage or guts. Zhao Qiang originally didn't either; he was just a normal person. Who isn't afraid? Who doesn't want to live forever? But Zhao Qiang couldn't watch Luo Xiaowei kneel before a man and offer herself to him. After all, she was his classmate and employee. In addition, Zhao Qiang discovered a secret: his brain seemed different from before. His neural reaction speed and computing power had increased several times over. A seemingly extremely fast movement was like slow motion in Zhao Qiang's eyes. That's why he dared to leap down like a monkey, calculating every landing point with millimeter precision.
Luo Wanfeng's hands and feet were ice cold. Although there was a raging fire just a short distance away through the window, the scaffolding had no warmth in the cold wind. The flames inside the window were being blown inward by the cold wind. Fortunately, otherwise the scaffolding would not have been a refuge. He could see his daughter on it but he was powerless to help her, and he couldn't even save his own life. Luo Wanfeng sighed inwardly.
With a creak, the iron pipe beneath Luo Wanfeng's feet suddenly snapped, and he plummeted downwards with it. Luo Xiaowei, who was peering out the window, was terrified at the sight. She covered her mouth with one hand and clutched her chest with the other, her eyes wide with fear.
Zhao Qiang had reached Luo Wanfeng's head, but just a second or two later, he could no longer reach Luo Wanfeng. The scaffolding's iron pipes broke off at Zhao Qiang's feet and collapsed down the building. The creaking and groaning sound made everyone's heart clench. Luo Wanfeng fell like a giant iron ball, and even though he waved his hands and tried his best to grab something, it was all in vain.
Seeing that his efforts were in vain, Zhao Qiang gritted his teeth and jumped down. Xu Xiaoya, upstairs, screamed. Deep down, she longed for Zhao Qiang's safety, not for him to sacrifice himself to save Luo Wanfeng. Even if she was selfish, people will have selfish thoughts in critical moments. This was not Xu Xiaoya's fault. Luo Wanfeng and Zhao Qiang held much less importance in Xu Xiaoya's heart.
Using the momentum of his leap, Zhao Qiang finally reached Luo Wanfeng's head. He grabbed Luo Wanfeng's back, and with a bang, several buttons on Luo Wanfeng's suit snapped under the force. However, the sleeves around Luo Wanfeng's arms secured him in Zhao Qiang's hand. Zhao Qiang raised his other hand, and the monstrous screwdriver suddenly extended into a hook shape, hooking onto the lowest iron pipe. The force of their fall stopped abruptly. Fortunately, the distance wasn't long; otherwise, it's hard to say whether the screwdriver could have withstood the falling force.
At that moment, the wind and snow were fierce, and a strong gust of wind swept up from below, carrying a lot of ash that choked people's noses and eyes. The male survivors at the window hurriedly hid inside the building. No one noticed how Zhao Qiang grabbed Luo Wanfeng and returned to the scaffold. Even Xu Xiaoya and Luo Xiaowei were blinded by dust. After rubbing their eyes, they saw that Zhao Qiang and Luo Wanfeng were already standing on the scaffold.
The two women hugged each other excitedly, and Xu Xiaoya said with some pride, "Don't worry, Xiaowei, Zhao Qiang is very capable. Your father will definitely be fine."
Luo Xiaowei was so happy that tears streamed down her face. She nodded heavily and said, "Yes."
Luo Wanfeng's nose and eyes were running, whether from fear or from the wind, he didn't know. He had just been on the verge of death, and he never wanted to experience that feeling again. "Thank you, young man," Luo Wanfeng said sincerely.
Zhao Qiang pointed to the ceiling: "Let's go up, you go first, I'll go last."
Luo Wanfeng's hands trembled and his legs went weak, making it difficult for him to stand steadily on the iron pipes. Zhao Qiang had no choice but to support him. There were still about ten meters to go back to Luo Xiaowei's window, including a section of scaffolding over two and a half meters long without horizontal iron pipes, which would be very difficult to climb. They could have gone back to the current floor, but Zhao Qiang observed that the fires in every window on that floor were too intense. Even against the strong wind, flames could still occasionally flicker out, so it was better to go back to the floor that had already been burned.
With one hand holding Luo Wanfeng's arm and the other tightly gripping the vertical iron pipe, Zhao Qiang said, "You step on my shoulders and I'll lift you up." Above that was a section of vertical iron pipe more than two and a half meters long without any horizontal iron pipe.
Luo Wanfeng was deeply moved and uneasy, saying, "This, how can this be? Besides, how will you get up there?"
With a creaking sound, the scaffolding collapsed, the lower levels crashing onto the plaza in front of the building, smashing several luxury cars to pieces! The upper levels were also no longer stable.
Zhao Qiang said sternly, "Don't worry about me, we don't have time to be polite here!" With that, Zhao Qiang released Luo Wanfeng's arm and squatted down.
Luo Wanfeng gritted his teeth, lifted his foot, and stepped onto Zhao Qiang's shoulder. Zhao Qiang straightened his body and pushed Luo Wanfeng upwards. Luo Wanfeng successfully grabbed the horizontal iron pipe above his head and then struggled to climb up. At this point, he was only a few meters away from Luo Xiaowei. Luo Xiaowei was clinging to the window, desperately stretching her arms out, hoping to grab her father's hand a second sooner.
Luo Wanfeng didn't rush to consider his daughter's feelings. Instead, he turned around, bent down, and offered his arm to pull Zhao Qiang up. To his surprise, Zhao Qiang jumped up from the spot, leaping a meter and a half into the air. He grabbed the iron pipe above his head with both hands, and then swung in the air before landing beside him.
Luo Wanfeng forgot the danger and gave a thumbs-up, praising, "Beautiful."
Zhao Qiang chuckled, "Just think of it as playing on the horizontal bar." Actually, it wasn't as simple as playing on the horizontal bar. Even if Zhao Qiang was good at the horizontal bar before, he wouldn't dare to do such a dangerous move at such a height. The reason he did it now was because he considered his own weight, the load-bearing capacity of the iron pipe, the resistance of his palms, the resistance of the iron pipe, the force generated when his body swayed, the influence of wind speed, and other factors to confirm that he had the ability before he did it.
The two exchanged a smile and continued climbing. The scaffolding swayed violently along the way, and it looked like it was about to give way. Fortunately, they had reached the window of the floor where Luo Xiaowei was.

Volume 2 [113] My Dad is XX
"Dad!" Luo Xiaowei's hand finally touched Luo Wanfeng's hand. She held it tightly, afraid that her father would fall again. Xu Xiaoya also grabbed Zhao Qiang's hand. The two women almost simultaneously pulled the two men into the window. Luo Wanfeng hugged his daughter before he could even stand up. Xu Xiaoya lifted her feet forward and then put them down. She had the urge to hug Zhao Qiang, but considering the many outsiders around and the fact that their statuses weren't the kind of people who could hug each other, Xu Xiaoya ultimately gave up. Actually, she had already hugged him once before. Now that everyone was safe, Xu Xiaoya's girlish reserve returned. Even if she was carefree, she couldn't just hug any man, could she?
A sharp crack echoed outside the window as the scaffolding that had just been supporting the two of them snapped completely, plummeting to the ground and crushing several cars that were already flattened. Luo Xiaowei peeked out and her face turned purple with fright. If her father were still on the scaffolding, he wouldn't have died ten times over!
Zhao Qiang peered out and saw that the fire downstairs showed no signs of abating. He wondered what was burning so fiercely, as large sections of the exterior wall were peeling off. Although the fire trucks had arrived, it would be difficult for them to spray water that high. If they stayed on this floor, it was not impossible for the floor slab beneath their feet to be burned through.
"Let's go." Zhao Qiang led the way, leaving this over-exploded place of survival.
A man shouted, "Leave? Where do you think you're going? I'm afraid there's nowhere better to hide than here."
Zhao Qiang said, "The rescue can't get up there in a while, and the fire on the lower floors is not going down. If it collapses, we won't even know how people died. So we need to go to the roof."
Another man exclaimed in surprise, "Go to the roof? Are you kidding me? Look up at the floors above, the fire is even worse there. How are you going to get through? Isn't that just suicide?"
Zhao Qiang said, "There's still a chance to cross the fire if we set off now, but if we delay any longer, we'll miss our chance."
Xu Xiaoya and Luo Xiaowei followed Zhao Qiang without hesitation. Although Luo Wanfeng hesitated, since what the two men had said made sense, he ultimately followed Zhao Qiang without saying anything. The four of them left the burning area and headed upstairs through the thick smoke and flames.
Zhao Qiang carried a blackened water pipe, clearing flames from the path as he went. He moved slowly, but thankfully no one was injured. After a long and arduous journey, they finally returned to the stairwell leading to the 28th floor. The fire on the upper floor was raging fiercely, sealing off the entire stairwell. In fact, the intense fire was related to Zhao Qiang's burning of the corpses, but Zhao Qiang would not reveal this. He only glanced at the blazing stairwell before leading the three of them to find another way. The two corpses were already charred.
Such a large building couldn't possibly have only one staircase. Even without Xiaowei's navigation, Zhao Qiang found a new staircase near the window in just five minutes. Moreover, the fire was weak here because there weren't many flammable materials.
"Help...help..." The cries for help were still carried on the cold wind outside the window. Zhao Qiang cleared away the burning objects in the stairwell and said to Xu Xiaoya, "You guys go up first, I'll see what's going on?"
Xu Xiaoya considered for a moment and said, "I'll stay with you; it'll make me feel more at ease." This was the truth.
Zhao Qiang saw that the window glass had long been shattered, but there was a layer of security bars nailed to the window. It was definitely not for theft prevention, but to prevent people from getting close to the window and causing danger. Zhao Qiang knocked down the security bars with an iron pipe a few times, and looked down. He saw two people standing on the scaffolding on the 25th floor. By the flickering firelight, Zhao Qiang vaguely recognized one of them as Zhang Lingfeng. This guy went out alone on the 28th floor to find a way to the roof. Why did he seem to be going further and further down?
Zhang Lingfeng seemed to hear a voice above him. He looked up and saw Zhao Qiang's face, though he couldn't recognize him at all. But no matter who it was, Zhang Lingfeng couldn't give up hope: "Save me! Help me!"
Upon hearing the sound, Xu Xiaoya and Luo Xiaowei exchanged a glance, both thinking to themselves, "This bastard has finally met his end!" Just a few dozen minutes ago, Zhang Lingfeng and the other two women had pretended to be lesbians, which was an extremely embarrassing thing.
Zhao Qiang naturally recalled Liu Yiyi's evaluation of Zhang Lingfeng, so he hesitated. He thought it better to let this spoiled brat with all his vices burn to death on the scaffolding or fall off the building, so that he wouldn't have to find another way to deal with him if he offended him in the future.
"Hurry up and save me! I'll give you money, as much as you want. You can even have power if you want. My dad is Zhang Weiguo. If you save me, you can do whatever you want in Donghai City!" Seeing that his superiors hadn't taken any action, Zhang Lingfeng began to persuade them.
Xu Xiaoya felt much safer with Zhao Qiang by her side. In a good mood, she couldn't help but mock Zhang Lingfeng's words: "So your dad is Li Gang. We can't afford to offend him."
No sooner had Xu Xiaoya finished speaking than someone shouted from below, "Xu Xiaoya? Xu Xiaoya! Is that you? I'm Qian Feihao, please help me get up here!"
Xu Xiaoya was stunned for a moment, then peeked out and took a closer look. The other person did indeed look a lot like Qian Feihao, except that his hair was all singed, and it would be hard to recognize him if you didn't hear his voice.
Xu Xiaoya said to Zhao Qiang somewhat embarrassedly, "They're our alumni, what should we do?"
Zhao Qiang said, "What else can we do but save them? Saving one is the same as saving two."
This direction is not on the same floor as the one where Luo Wanfeng was rescued. The scaffolding here has not yet collapsed, but it is all teetering on the brink of collapse. The fire was too fierce, and with the strong wind and the heavy weight of the scaffolding, it is reasonable for it to collapse.
Zhao Qiang tried to lean out and reach the water pipe downwards. Zhang Lingfeng and Qian Feihao grabbed the scaffolding with one hand and desperately reached upwards with the other, both wanting to be the first to be rescued. However, the water pipe was not long enough for them to reach. Zhao Qiang could only say, "Could you two please climb up a bit? I can't reach you from here."
Qian Feihao recognized the voice and said, "So it's Zhao Qiang. Please forgive me if I offended you before. I deserved to die, and I even wanted to cause you trouble." Qian Feihao was a pragmatic man who knew he couldn't offend Zhao Qiang at this time, so he took the initiative to admit his mistake.
Zhao Qiang said, "Hurry up and climb, the iron pipes below aren't very sturdy anymore."
Zhang Lingfeng cursed, "Damn it, how am I supposed to climb? I fell from the 28th floor. If I could climb, I would have gotten up there already. Some places are too high up, and my hands can't even reach the iron pipes above."
The situation is the same as before with Luo Wanfeng. There is a gap of more than two and a half meters above Zhang Lingfeng's position on the scaffolding. Qian Feihao tried to climb on the vertical iron pipes, but he failed three times, whether because he had run out of strength or because the iron pipes were really slippery. Instead, he made the scaffolding shake even more violently.
"Damn it!" Zhao Qiang cursed as well, shouting down, "Two of you, cooperate! Cooperate! Understand?"
Zhang Lingfeng wasn't stupid; he suddenly realized, "I understand, I understand. You, come here and squat down!"
Qian Feihao was taken aback. One person's height wasn't enough, but couldn't the two of them together make up the height? But what if this rich kid abandoned him and left him at the bottom? Qian Feihao said, "You squat down first so I can climb up, and then I'll pull you up."
Who is Zhang Lingfeng? He's a big shot in Donghai City, someone whose mere presence makes the ground tremble. Yet here he is, being bargained with by Qian Feihao. He raises his hand and slaps him across the face. But Qian Feihao isn't one to be trifled with either. As a physical education student, his reaction is quick. He lowers his head and avoids Zhang Lingfeng's slap. Zhang Lingfeng's rude and unreasonable behavior makes him even more determined: he absolutely cannot be someone else's stepping stone, or he won't even know how he died.
With a snap, another section of the scaffolding connecting to the wall broke under its own weight. The two people on the scaffolding had moved a bit too violently, causing the iron pipe to tremble even more violently. Zhang Lingfeng shouted hysterically, "Squat down! I order you to squat down!"
The scaffolding was extremely dangerous. In the critical moment, Qian Feihao unleashed a strength that no ordinary person could match. He pushed off with his feet on the iron pipe, grabbed the vertical iron pipe with both hands, and in a flash, he grabbed the iron pipe more than a meter above his head. He pulled his body upward and left the lower level.
Seeing the situation was bad, Zhang Lingfeng became even more determined. He released the iron pipe with both hands and grabbed Qian Feihao's calves from below. Qian Feihao could have climbed up by doing just one more pull-up, but with his legs held by Zhang Lingfeng, he couldn't complete the movement no matter how strong he was, and he was left hanging in mid-air.
Volume 2 [114] Please accept my three bows
"I'll fuck your mother, let me go!" Qian Feihao cursed.
Zhang Lingfeng also cursed: "You son of a bitch! You think you can escape alone? No way! We'll die together, no matter what! Who was it that just said they wanted to become sworn brothers with me, sharing both hardship and happiness!"
It's likely that Qian Feihao made a boast when he and Zhang Lingfeng were in trouble together. Given Zhang Lingfeng's temperament, he couldn't possibly not reveal his identity, and Qian Feihao would naturally try to curry favor with him. But now, with his life at stake, he doesn't care about all that anymore.
Luo Xiaowei, who was upstairs, remarked, "When dogs fight, they get all worked up."
Luo Wanfeng said to Zhao Qiang, "Zhao Qiang, I think you should save them. You're a businessman; you should know the difference between saving them and not saving them." Previously, Luo Xiaowei had secretly introduced Zhao Qiang to her father.
After a moment's thought, Zhao Qiang realized that Luo Wanfeng's words made sense. If Zhang Lingfeng and Qian Feihao fell and died, it wouldn't really affect him much. At most, he would be burdened by the thought of not helping someone in distress, but that burden was so light that Zhao Qiang could ignore it. But what if he saved Zhang Lingfeng? After all, he was Zhang Lingfeng's savior. Even if Zhang Lingfeng didn't repay the favor, he wouldn't cause him any trouble. If Zhang Lingfeng was the kind of person who neither repaid the favor nor wanted to cause him trouble, then he could only consider himself unlucky. Everything in this world is a gamble. If you bet right, you win everything; if you bet wrong, you lose everything.
Zhao Qiang nodded to Luo Wanfeng: "Uncle is right, I know what to do." After saying that, Zhao Qiang climbed onto the window. Xu Xiaoya tried to pull him back, but Zhao Qiang was quick and jumped onto the scaffolding outside the window.
Luo Xiaowei said to Luo Wanfeng with some resentment, "Dad, it's dangerous for you to send Zhao Qiang to rescue people!"
Luo Wanfeng, however, was confident: "Don't worry, he can handle it. This kid is a talent; his eyes, hands, and feet coordinate better than a computer! Otherwise, he wouldn't have been able to save me before."
Xu Xiaoya originally wanted to complain about Luo Wanfeng, but when she heard Luo Wanfeng say that about Zhao Qiang, she changed her mind. "That's right. If Zhao Qiang didn't even have this much ability, he wouldn't have been able to score higher than me in the midterm exam. He's so abnormal that he doesn't need to do any calculations to solve any test questions."
Zhao Qiang was confident he could come down to rescue people. He quickly scanned the surroundings with his X-ray glasses. Although his weight added to the scaffolding, it shouldn't collapse within a minute or two. Using his running shoes for cushioning, Zhao Qiang reached Zhang Lingfeng's side in a few seconds. Zhang Lingfeng was still clinging to Qian Feihao, who was about to lose his grip on the iron pipe. He was practically crying and begging for mercy: "Zhang Lingfeng, please let me go! I can't hold on much longer! If you keep holding on, we'll both die!"
Zhang Lingfeng was a ruthless man, and he cursed, "Damn it, if we die together, we die together!"
Zhao Qiang patted Zhang Lingfeng's lower back: "Hey, stop shaking, you're really going to die if you keep shaking like that!"
"Ah!" Zhang Lingfeng was startled. He had no idea that Zhao Qiang had come down. He was suddenly patted and felt like he had encountered a ghost. In his shock, Qian Feihao struggled and broke free of Zhang Lingfeng's grasp with one foot. Then, he stepped on Zhang Lingfeng's head with that foot, and Zhang Lingfeng could no longer hold on to Qian Feihao and flew downwards!
Zhang Lingfeng's mind went blank. Even if he was the biggest thug in Donghai City, what difference would it make? At this moment, even if he were the biggest thug in the country, it wouldn't matter. Humans are fragile creatures, and life is worthless. You can die anytime, and he'll die a horrible death, probably a pile of minced meat, unrecognizable even to his parents. At this moment, Zhang Lingfeng felt a pang of regret. He had truly wasted his life before!
Zhao Qiang didn't expect Zhang Lingfeng to be so weak, but he reacted very quickly, grabbing Zhang Lingfeng by the back. He had done this action before, so he was very familiar with it. Zhao Qiang was confident that he could save Zhang Lingfeng, but he didn't expect that Zhang Lingfeng's suit was of poor quality. With a tearing sound, Zhao Qiang was left with only a piece of back fabric in his hand, while Zhang Lingfeng continued to fall downwards, flailing his arms and legs.
"Damn it!" Zhao Qiang cursed to express his anger. Then he kicked off the scaffolding and chased after Zhang Lingfeng. What bad luck! He had to repeat the same rescue action twice today. If his brain could break down the whole process in slow motion, Zhao Qiang would never have dared to do this!
Zhang Lingfeng let out a piercing scream as he flew downwards, wanting to vent his anger in his final seconds. Perhaps Zhang Weiguo, the director of the Donghai City Public Security Bureau, was watching this scene from below. Suddenly, Zhang Lingfeng's belt tightened, and his downward momentum immediately slowed. Then, Zhang Lingfeng's falling direction changed, and he was thrown back onto the scaffolding with a thud. Several horizontal iron pipes supported Zhang Lingfeng's body, and Zhao Qiang also landed on them shortly after.
Zhao Qiang broke out in a cold sweat after performing such a dangerous high-altitude jump. The price he paid for saving Zhang Lingfeng this time was not low. If this guy caused him trouble in the future, Zhao Qiang would really regret it to the core.
Zhao Qiang nudged Zhang Lingfeng, who was clinging to the scaffolding, and said, "Hey, can you still climb? We have to get up here right away, or this place will collapse."
Zhang Lingfeng, his eyes vacant and blank, replied, "Oh, climb up."
Zhao Qiang thought to himself, "Oh no, is he scared out of his wits?" But this wasn't a place to stay. Zhao Qiang didn't care whether Zhang Lingfeng was really stupid or not. He looked after him from the side. Zhang Lingfeng mechanically climbed back up. When he returned to the gap in the scaffolding that was higher than a person, Zhao Qiang supported Zhang Lingfeng's buttocks from below and helped him up. After Zhang Lingfeng climbed up and sat down, he paused for two seconds, then suddenly turned around and reached down to pull Zhao Qiang up. This action made Zhao Qiang a little relieved. This guy didn't seem to be ungrateful. At least he knew to give him a hand.
Zhao Qiang waved to Zhang Lingfeng, then pushed off the iron pipe with his feet and grabbed the iron pipe above his head with both hands. He swayed twice and flipped onto the upper scaffolding. Zhang Lingfeng was still a little confused, but he finally spoke, "Damn!" It was hard to tell whether this was a compliment or an insult for Zhao Qiang's strength.
The rest of the way was much easier. Soon the two reached the window. Luo Wanfeng helped pull Zhang Lingfeng up, while Zhao Qiang easily jumped in himself. Zhang Lingfeng sat on the ground catching his breath for a dozen seconds, then suddenly jumped up and yelled, "Where's Qian Feihao? That bastard! Get over here!"
At this moment, no one saw Zhang Lingfeng as a bully who preyed on young girls. His face was covered in soot, his clothes were torn, and he smelled foul. He probably wet himself in fright when he fell. Xu Xiaoya was confident that she could knock him down with one punch, so she didn't hold back: "Take care of yourself first. Don't think you're something special. You're just a pile of stinking dog shit!"
These words were quite impolite, even worse than an insult. Luo Xiaowei gently tugged at Xu Xiaoya, reminding her not to go too far, but to her surprise, Zhang Lingfeng didn't care at all. After failing to find Qian Feihao, he turned around and knelt down before Zhao Qiang!
He knelt down, something even during holidays wouldn't allow Zhang Lingfeng to kneel and kowtow to his parents. "My benefactor, you are my second parents, please accept my three bows!" Bang, bang, bang, Zhang Lingfeng didn't give Zhao Qiang a chance, his head hitting the ground three times, scaring Zhao Qiang so much that he hurriedly jumped aside. This guy has gone mad.
Zhang Lingfeng was perfectly clear-headed. His near-death experience had taught him many lessons. Power and money are meaningless without life; they're worthless if you can't enjoy them. Preserving one's life isn't about having more followers. Like today, he'd brought a few men, but they scattered when the fire started, leaving him unattended. The best way to survive and enjoy life was to become strong, so that any danger could be overcome. Zhao Qiang's actions had impressed Zhang Lingfeng. While he wasn't quite ready to become Zhao Qiang's apprentice yet, building a good relationship was essential. Moreover, Zhang Lingfeng genuinely felt gratitude. The experience of being between life and death was unbearable, and Zhao Qiang had given him a chance to enjoy life again. He felt only a deep gratitude could express, so, true to his impulsive nature, he immediately knelt down.
