These beings possess an insatiable desire for everything in the human world. Lu Xuan speculated that the true world inhabited by extraterrestrial demons was most likely an exceptionally monotonous and empty place, which explains their boundless desire for everything in the human world. Because they lacked it there.
Extraterrestrial demons have no physical body; they are a special form, a mixture of spirit, energy, and some other peculiar characteristic. The most terrifying aspect of these beings for cultivators is their ability to specifically target and destroy the mind. This is especially true during the tribulation of inner demons, when they almost inevitably strike. Without prior preparation, cultivators are essentially helpless against them.
When Yin Yue broke through to the mortal realm, she must have attracted the attention of countless high-level beings. It's highly likely that she was targeted by extraterrestrial demons. Although under normal circumstances, these extraterrestrial demons would find it difficult to directly enter the mortal realm and possess others, the fact that Yin Yue's divine soul was fragmented, leaving her divine sense extremely weak, presented them with the perfect opportunity to invade.
Therefore, those shattered souls were seized by an unknown extraterrestrial demon. And now, with Lu Xuan's soul-summoning technique, the extraterrestrial demon who possessed the remnant soul of Silver Moon naturally sensed it.
Possessing a fragment of a soul is naturally inferior to possessing the main soul, or even a living person. Therefore, this extraterrestrial demon attacked Lu Xuan without hesitation.
Because it had been lurking in the human realm for many years, it had secretly accumulated considerable power. This attack was a full-force strike. It was confident that even if its opponent was an old monster at the Nascent Soul stage, they might not be able to stop it. Moreover, it already knew that the spiritual energy in this generation was scarce, and there were very few people at the Nascent Soul stage. The one before it was clearly a Core Formation stage cultivator at a glance.
Although one may possess profound magical power, the relationship between spiritual power and magical power is not significant. Many cultivators with profound magical power may not necessarily have strong spiritual power.
Lu Xuan felt a piercing pain in his brain. An external consciousness was frantically assaulting his soul.
"Hmph!" Lu Xuan snorted coldly. He unleashed the Divine Shock Thrust. A scream rang out from within the black mist.
But the struggle did not end there.
Lu Xuan could sense that the Divine Shock Thorn had momentarily halted the opponent's attack. However, it hadn't directly repelled the opponent. This extraterrestrial demon that had invaded the human realm had forcefully withstood the Divine Shock Thorn.
However, the brief respite just now gave Lu Xuan time to counterattack. With a thought, Lu Xuan's entire life spirit condensed into one.
To the extraterrestrial demon, it only felt the opponent's divine soul power suddenly contract and coalesce. Without thinking, it seized the opportunity to invade. Then it crashed headlong into an impenetrable wall.
In the realm of consciousness, Lu Xuan coldly gazed at the beautiful woman before him. Clearly, the extraterrestrial demon was using the form of the Silver Moon's true form. However, the woman's image quickly transformed into Lu Xuan's own.
This is a common tactic used by extraterrestrial demons. They usually like to appear in the form of the attacked party, disguising themselves as the opponent's inner demons to interfere with their Dao heart. However, such petty tricks are naturally meaningless to Lu Xuan.
"Interesting, you're quite a special human, aren't you?" Lu Xuan said sinisterly. It couldn't help but be surprised. Not only had Lu Xuan withstood its fatal blow, but he had also countered using some kind of divine soul technique.
"Aren't you even more special? A mere wisp of a remnant soul can attract an extraterrestrial demon of your caliber?"
"Hehe, you're quite knowledgeable! I'm starting to get interested in you. Your soul-binding technique is something I've never seen before. But it doesn't matter, I'll soon know all your secrets."
A cultivator's soul is naturally countless times stronger than that of an ordinary person. However, the ability to freely condense one's soul and clearly communicate with it in the consciousness space, as Lu Xuan possesses, is something only seen in higher-level cultivators. It's important to understand that cultivating the soul is extremely difficult.
It is invisible and intangible. There are very few secret techniques in the mortal realm that can cultivate the divine soul. In fact, even in the spirit realm and the immortal realm, they are extremely rare. The Divine Refining Technique that Han Laomo obtained in his later years was even a forbidden technique in the immortal realm.
Throughout history, countless cultivators have fallen prey to extraterrestrial demons at the Heart Demon Barrier due to unstable souls. Among them were many exceptionally talented individuals, yet they all ultimately succumbed to this hurdle.
The extraterrestrial demon's entire body suddenly exploded into a cloud of black mist, directly enveloping Lu Xuan within it.
"No matter what secrets you have, I will become you in an instant." This kind of direct confrontation of souls is extremely dangerous for cultivators, but for extraterrestrial demons, it is just the most ordinary attack.
However, it quickly realized something was wrong. Lu Xuan stood still, not moving an inch. But the black mist of divine sense it had transformed into could not shake Lu Xuan in the slightest.
Taoism has its own set of visualization methods, which clearly distinguish between the skin, flesh, bones, and internal organs from the outside to the inside.
Buddhism also has its own visualization methods, which generally involve visualizing the Buddha, lotus flowers, and other symbolic objects.
Lu Xuan, however, combined the two approaches to develop his own visualization method, specifically for tempering his soul. He started with the external aspects of Daoism, moving from the outside in, and eventually covering his entire body.
Then, using Buddhist techniques, he isolated his entire visualization process, creating a visualization diagram. Yes, that diagram depicted himself.
Lu Xuan always believed that divine thought is a special manifestation of spiritual power extending from the physical body. Therefore, they should complement each other. Hence, human cultivators do not need to use external objects to aid their visualization. Even if you obtain a portrait of the Buddha or the Taoist patriarch, it cannot compare to your own.
To strengthen one's soul, it shouldn't be a simple matter of cultivating the soul itself. Rather, it requires the simultaneous progress of both the physical body and the spirit, after which the soul will naturally be strengthened. Therefore, Lu Xuan used his own physical body as the foundation to create a visualization diagram whose essence was himself.
He believed that the reason most cultivators, after achieving physical strength, were unable to project their divine souls was because a certain disconnect had formed between their souls and bodies. Theoretically, the divine soul doesn't require special cultivation; it should continuously improve as the cultivator's cultivation level increases.
The root of this problem lies in the fact that the cultivation method is not compatible with oneself. This is essentially inevitable, because 99% of cultivators practice methods left behind by others.
No matter how unique the physical constitution, those cultivation methods were all created by their creators based on their own physical data. Later generations of cultivators can never achieve a perfect match. Therefore, almost all cultivators experience this disconnect. This is also why the soul is difficult to cultivate.

Chapter 515 Research? Torture?
This was the first time the extraterrestrial demons had encountered such a state. The cultivator's soul and body were perfectly integrated, with almost no flaws.
This doesn't mean Lu Xuan had no psychological weaknesses, but rather that his weaknesses were all sealed off by some kind of solid fortress. The extraterrestrial demons couldn't touch him at all.
The next second, golden lightning crackled around Lu Xuan. This was the Evil-Repelling Divine Lightning, specifically designed to counter extraterrestrial demons. Although Lu Xuan hadn't learned the Lightning Sacrifice Technique, making it difficult to kill this extraterrestrial demon directly, he could still inflict significant damage.
"No, wait! I can sign a Heavenly Demon Contract with you, and serve you for ten thousand years, just to spare my life!"
The Evil-Repelling Divine Thunder cannot actually kill extraterrestrial demons directly. At least, during the Inner Demon Tribulation, the extraterrestrial demons encountered could not be directly killed by the Evil-Repelling Divine Thunder. Lu Xuan remembered that ordinary cultivators needed to use the leaves of Golden Thunder Bamboo to refine a special thunder talisman to kill those things directly. Only then could they inflict fatal damage on the extraterrestrial demons.
But this creature before them seemed different. It had likely spent too long in the mortal realm and absorbed a large amount of Silver Moon's memories, making it unlike any other extraterrestrial demon. More importantly, this fellow had actually mentioned something called a Demon Contract.
This thing is extremely high-end in the mortal world. Under normal circumstances, it only appears in the immortal realm. Only Han Laomo, as the protagonist, is qualified to use it in the spirit realm. Normal spirit realm cultivators, even those at the Mahayana stage, may not have even heard of it.
"The Heavenly Demon Contract? This is not a method that ordinary extraterrestrial heavenly demons can use."
Hearing Lu Xuan's question, the extraterrestrial demon opposite him was also shocked.
“I should be the one saying that. I was just saying it casually. How could a cultivator from the human realm possibly know about something like the Heavenly Demon Contract? You are indeed no ordinary cultivator.”
"I've heard of the Heavenly Demon Contract, but I've never actually seen one. How do I know you might tamper with it? So, forget it. It's best not to trust extraterrestrial demons."
As Lu Xuan spoke, he increased the power of the Evil-Repelling Divine Thunder in his hand.
"Wait, wait, I can open my mind and let you place a restriction on me. I swear in the name of the Heavenly Demon Ancestor."
Oaths from extraterrestrial demons are naturally worthless. However, oaths sworn in the name of the Demon Ancestor are different. The legendary Demon Contract is guaranteed by the Demon Ancestor. This is the only known contract and oath that has binding power over extraterrestrial demons.
