Wuming exclaimed in surprise and swung his Hero Sword repeatedly, unleashing righteous sword energy that cleaved towards the black mist.
In an instant, the wisp of black mist was cleaved into countless fragments, transforming into countless wisps of black mist.
However, these malevolent black mists quickly coalesced again, reforming into a massive, demonic black mist.
"Hehehe... Ignorant humans, I am the embodiment of evil thoughts, possessing this immortal body. You mere mortals cannot kill me!"
A smug demonic face emerged from the black mist.
His smile was sinister and terrifying!
"This monster is unkillable?"
Wuming was terrified.
Faced with an unkillable monster, even the usually calm and collected Nameless couldn't help but panic.
Li Yao was also in a state of utter confusion.
He hadn't expected that the Demon Lord was unkillable.
The Demon Lord is a being similar to a spiritual entity, formed from the evil thoughts accumulated over thousands of years in the Sword Realm.
Therefore, the Demon Lord also possesses a special ability: immortality.
As long as the evil thoughts of swordsmen throughout the world persist, the Demon Lord can live forever in this sword realm.
Humans are not saints; they cannot be completely free of defilement and desire. Evil thoughts will always exist in the human heart.
Therefore, the Demon Lord can be considered an immortal being.
However, the pursuit of immortality by Indra is vastly different from the immortality of the Demon Lord.
Although Indra consumed the Dragon Essence and Phoenix Blood, theoretically he could achieve immortality.
However, even if Indra is decapitated, he will still die.
Unlike the Demon Lord, who is truly immortal and indestructible.
This is somewhat similar to the Evil Sword Immortal in the world of Chinese Paladin.
Therefore, Li Yao couldn't think of a good way to eliminate the Demon Lord for the time being.
"Prepare to die, humans!"
The demon suddenly opened its gaping maw.
Black energy surged from the gaping maw, and countless black energy swords shot towards Li Yao and Wuming.
Li Yao and Wuming hurriedly brandished their swords, relentlessly shattering the densely packed black energy swords that were shooting towards them.
"Hehehe... Ignorant humans, resistance is useless."
"This sword pool contains countless evil sword intents and thoughts, inexhaustible, enough to exhaust you to death."
"I advise you to obediently let me possess your bodies!"
"Hehehe..."
The Demon Lord laughed wildly and unrestrainedly, his smile twisted and terrifying.
Li Yao and Wuming felt a chill in their hearts.
The Demon Lord is right; continuing like this is definitely not a solution.
Suddenly, an idea flashed through Li Yao's mind.
Since the Demon Lord is formed from evil sword intent and sword spirit, and the "Absorption Technique" can absorb not only internal energy, but also true essence, martial arts skills, and vital energy.
Therefore, the "Great Dao True Scripture," which incorporates the "Absorption Technique," might be able to absorb sword intent and sword spirit.
After thinking it over, he immediately activated the "Great Dao True Scripture" and poured it into the Peerless Divine Sword.
Instantly, the Peerless Divine Sword burst forth with red light, and a tremendous suction force erupted from its blade.
Immediately, the surrounding evil thoughts, demonic energy, and sword intent converged towards the Peerless Sword.
The Peerless Sword was like a bottomless black hole, greedily devouring the sword intent and sword spirit coming from all directions.
"Huh? What's going on? Why do I feel weaker and weaker?"
The demon king was terrified, feeling as if something had drained the energy from his body.
He transformed into a cloud of black mist, which grew smaller and smaller.
Moreover, above the black mist, strands of black lines surged toward the Peerless Divine Sword like a tide.
"This is bad, my sword intent is getting weaker and weaker!"
Wuming was equally shocked.
"Get away from me!"
Li Yao flipped his hand and unleashed a palm strike, sending Wuming flying several feet away.
The "Absorption Technique" doesn't distinguish between good and bad; as long as it's within a certain range, it can absorb anyone's internal energy or martial arts skills.
"What bizarre kung fu!"
Wuming was stunned by the scene before him.
He had been traveling the martial arts world for many years, but he had never seen such a strange and magical skill.
"ah……"
"My body..."
"Please, please, spare me this once!"
The Demon Lord was terrified.
Since he came into existence, he has been growing stronger every day.
Because, in the human world, evil thoughts and intentions of swords are constantly being generated.
Nourished by these continuous streams of sword thoughts and sword intent, he grew stronger and stronger.
However, his sword intent and sword spirit are now constantly disappearing.
This is terrifying, unbelievable.
He never imagined that he would one day become weak.
It might even one day disappear.
His demise terrified him.
An unprecedented fear.
"Demon Lord, aren't you immortal?"
"Today, I will let you taste the flavor of death."
Li Yao wore a mocking smile.
"No, I don't want to die..."
"Please, have mercy on me!"
The demon king pleaded desperately.
However, Li Yao ignored it.
The demon king's pleas grew weaker and weaker, and his black mist became thinner and thinner.
Even the color of the sword pool changed, becoming paler and clearer.
Soon, the Demon Lord was completely absorbed into the Peerless Divine Sword.
The Sword Pool has been transformed into a crystal-clear pool.
"This...this Demon Lord just died like that?"
Wuming was dumbfounded.
He never expected that the demon-like Demon Lord would be absorbed into the Peerless Sword by Li Yao.
This is absolutely incredible.
It completely overturned his entire worldview.
Li Yao thought for a moment, then shook his head and said, "The Demon Lord is only temporarily dead."
Wuming paused for a moment, then asked, puzzled, "What do you mean by that?"
Li Yao explained, "The Demon Lord is formed from the evil sword thoughts of swordsmen. As long as there are swordsmen in this world, there will definitely be evil sword thoughts. These evil sword thoughts gather in the Sword Pool of this Sword Realm, and over time, they will give birth to another Demon Lord."
Wuming nodded in sudden realization.
Then he sighed and said, "Yes, the human heart is unpredictable, and evil can never be eliminated. This is the devil hidden in the heart of a swordsman."
Then, he turned his gaze to the Peerless Sword in Li Yao's hand and couldn't help but ask, "Why is this Peerless Sword able to absorb the Demon Lord?"
Li Yao shook his head and casually explained, "This is because I have been practicing a certain martial art."
He didn't explain much.
Seeing that Li Yao was unwilling to say more, Wuming did not press the matter further.
After all, most martial arts techniques are not easily revealed to others.
There's a reason why Li Yao didn't directly use the "Absorption Technique" this time, but instead used the Peerless Sword to unleash it.
Firstly, he worried that the "Absorption Technique" was not powerful enough.
After all, this technique came from the number one world under heaven. Although it had been integrated and optimized by the "Great Dao True Scripture", he was still worried that this technique would not be powerful enough in the world of Fengyun.
The Peerless Sword was transformed from a divine stone, which could amplify its power twentyfold.
When the Absorption Technique is used by the Peerless Sword, its power is amplified twentyfold.
Secondly, he was worried about being controlled by the sword intent of the 'Twelve Profound Yin Swords'.
The Sword Pool contains the sword intent of the Twelve Profound Yin Swords.
The Twelve Swords of Xuan Yin is a magical sword technique with its own life and consciousness. It is also a supreme demonic sword technique that can find its own host, lead people astray, and is mysterious and unpredictable.
This sword technique is the only one in the entire series that doesn't require starting from the basics or going through the process of practicing sword moves to comprehend the sword intent.
