In the underground space, a trace of solemn aura was permeating, two figures were sitting cross-legged, Lin Yi was staring intently, staring at the immortal body in front of him, his eyes were scorching, flashing with amazing symbols.

He wants to peek into the mysteries of human immortals and find the immortal characteristics of true immortals, so as to comprehend the mysteries of immortality, hoping to have greater comprehension and progress in his immortal body.

"Immortal body, immortal and immortal, the mystery of immortals"

Lin Yi muttered to himself, but he was full of solemnity, because he couldn't see through the mystery of the human immortal body, which was unimaginable. The mystery of the immortal could not be peeped into, but he did not give up and was studying it carefully.

Outside the human immortal's body, there was a layer of hazy light, blocking his peeping, but it was difficult for him. I saw that Lin Yi's eyebrows were glowing, and a little bit of glow diffused out, penetrating the void and passing towards that layer of hazy light.

In an instant, Lin Yi only felt an unprecedented impact, the spirit of the Yuan Shen was shaken, and then the turmoil was endless, as if it was about to burst, and there was an amazing pain, very strong.

He felt that this kind of peeping seemed to be counterattacked by the instinct of the human immortal body, of course, it was just instinct, so it didn't hurt him much.

"What is immortality?"

Lin Yi had a headache, and he was a little disappointed when he saw that he couldn't peek into the mysteries in the human immortal's body. However, the next moment he made a decision to enter the body of the human immortal to carefully inspect and comprehend the so-called immortal.

He stood up, suddenly turned into a flash of light, rushed into the body of the human immortal, and instantly came to the sea of knowledge of the human immortal body. And as soon as he entered here, he was immediately subjected to powerful oppression, and even infinite killing machines swept over to suppress his physical body.

This is equivalent to an outsider, invading the other person's body, and then suffering the body's instinctive extermination. This instinct is very strong, even if the human immortal body has been dead for countless years and the true spirit has been extinguished, there are still residual thoughts in the physical body.

Lin Yi has always doubted whether this person's immortal body is really dead, logically speaking, the existence that belongs to the immortal cannot reach the level of immortality in time, and it is still not that simple.

And right now, the human immortal body has the instinct to hit and counterattack, causing him the dilemma of hitting. If it takes a long time, there will inevitably be a danger of being crushed, which is a very dangerous thing in the human immortal body.

If it weren't for the fact that he blocked it with the mysterious blue lotus, and even wrapped himself with the human emperor's qi, he had reached an ability to weaken the counterattack. Soon, Lin Yi knew that he couldn't hold out for long and had to seize the opportunity.

As soon as the Yuan Shen moved, his thoughts swept out like a sea, invading the body of the immortal, and began to carefully and seriously carry out the mystery of the immortal, what secrets did this human immortal have in the body?

In his mind, the flesh of the human immortal was boiling, and the blood and qi were tumbling, as if he had been stimulated by something. Lin Yi originally wanted to suppress it, but the next moment he gave up, and instead carefully and carefully observed the blood of the human immortals.

But the difference between living beings is their own blood, so what is the difference between fairy blood? And what is the difference between the blood in the body of a human immortal and the so-called immortal blood obtained by himself, and whether there is any secret in this.

Bang...

The blood of the human immortals boiled and gushed endlessly, sweeping through the whole body like a stormy wave, like an ancient fierce beast awakening, exuding terrifying might.

Lin Yi collected his mind, observed it wholeheartedly, and soon discovered something unusual. He was surprised to find that the blood in the human immortal body was actually higher than the so-called immortal blood he had obtained, even beyond his imagination.

The boiling blood, exuding this supreme power, and the breath belonging to the immortal is being released. And what is amazing is that this mysterious brilliance flashes in these bloods, and the Dao symbols flicker, as small as a strand of hair.

If Lin Yi hadn't looked carefully, he probably wouldn't have been able to see it, but at this moment, he immediately realized that these symbols had this secret.

Sure enough, as he got deeper, he finally got a little bit of information, and these symbols were immortal marks. Such a discovery made Lin Yi's heart tremble, and it was unbelievable that there were so many immortal marks in the body of the human immortal.

"No wonder, the so-called immortal marks turned out to be like this." Lin Yi understood, and his heart was happy.

He immediately collected his mind and comprehended it wholeheartedly, and the tiny symbols flickered, and the due mysteries emerged one by one under the divine thoughts.

Lin Yi got the opportunity and found the immortal marks from the human immortal body, and after careful understanding, he had a huge harvest. Immortal marks, representing the Dao of this Immortal Gu, is an avenue that has been extinct, and compared with today's Dao of Heaven and Earth, it is too different.

With such an immortal scar, Lin Yi found an opportunity to peek into the way of the Immortal Gu, and patiently comprehended and observed it little by little, again and again, and finally he couldn't bear it anymore.

Burst!

Inside the cave, a figure flickered out in embarrassment, opening its mouth and spurting a mouthful of blood. Lin Yi was covered in scars, but his eyes were filled with this strong light, as if he had gained great understanding.

He was excited, crossed his knees here to enter the cultivation, and soon, the immortal body returned to its peak. Then, Lin Yi once again turned into light and flew into the body of the human immortal, continuing the enlightenment just now.

In this way, he was enlightened again and again, tirelessly, forgetting time, not knowing how long it had passed, until one day, Lin Yi suddenly felt an unprecedented comprehension, coming from the body of a human immortal.

He comprehended the immortal marks in the blood of all the immortals, and the Dao symbol flashed out, and it actually circled around his own body, and then he was madly imprinted on his body, and there were bursts of sonorous sounds.

At this time, Lin Yi discovered his own changes, and with the immortal mark brand, he was actually swallowed by the primordial avenue symbol above the body, and there was not a single one left, and all the immortal marks were absorbed.

This is not the end, as the immortal marks are absorbed, the Great Dao symbol undergoes a metamorphosis, evolving to a higher level, and finally merging into the physical body, forming a stronger and closer connection.

Moreover, in this process, Lin Yi felt that the flesh had undergone a mysterious transformation, the undead matter was boiling, and some undead substances that had not been absorbed by the flesh suddenly melted and were absorbed by the flesh cells.

"It's... Immortal properties? ”

Suddenly, Lin Yi's face was shocked, and then he was extremely happy. He saw that in the body of the human immortal, there was suddenly a trace of mysterious light beating, very secretive, if he hadn't been paying attention to it at all times, he might not have been able to find it.

These rays of light are faint, but they penetrate this indelible, immortal aura. This may be the so-called immortal characteristic, which belongs to the special ability of true immortals, no wonder the human immortal body can remain immortal for countless years.

After Lin Yi felt this nature, he immediately devoted his mind and tried his best to study and comprehend. In an instant, he seemed to have returned to the distant and mysterious Immortal Ancient Era, and seemed to have turned into a human war immortal, fighting in all directions, invincible.

It's a very realistic feeling, and if he hadn't realized who he was, he would probably have been lost here. Such a magical and strange thing made him immersed in it, looking for the mystery of this immortal gu, the avenue was in front of him, and it was never clearer.

"This is the Dao and Law of the Immortal Gu?" A murmur came from within his heart.

Lin Yi didn't know if he was in the process of comprehension at the moment, or if he was really in the Immortal Gu, of course, he still kept this trace of true spirit immortal, so there was no mystery problem.

And in this process, the human immortal body suddenly underwent a mutation, a thread, a mysterious silk thread spreading, and then wrapped the body, invaded the sea of knowledge, and acted on Lin Yi's body.

This is the immortal scars, intertwined one by one, wrapping his body, forming a kind of cocoon intertwined with immortal marks, exuding a burst of brilliant immortal light.

Lin Yi was in it, feeling the vast avenue, the Dao in his body was boiling, the blood in his body was tumbling, and he was completely aroused, roaring and galloping, washing his original body.

Immortal matter, immortal characteristics, the two things suddenly showed a hint of fusion, causing Lin Yi's physical body to undergo an astonishing and mysterious change, as if he had experienced another transformation of life and death.

Immortal and immortal, immortal and incorruptible, the physical body is really evolving in this direction, Lin Yi himself does not know, at this moment, because of the appearance of immortal marks, because of the discovery of immortal characteristics, the physical body was finally swallowed by the primordial avenue in his physical body, and he grew and evolved himself.

And his Yuan Shen, only a day later, suddenly couldn't withstand the instinctive counterattack of the human immortals, and immediately came to his senses. In the end, I had to take a break, and then realize my harvest this time, and finally enter the human immortal body again to continue to comprehend.

Lin Yi was shocked to find that the Dao of the Immortal Gu was very different from the present, but there were still very similar places, such as the fundamental pursuit of the Dao and the Law now is to cross the Immortal Gate and achieve the true Immortal, which is similar to the Immortal Gu.

However, Lin Yi learned from it that there were no more immortals in the world after the Immortal Gu. The path to becoming an immortal has been extinct, and the only way now is to create your own Tao and Dharma to adapt to this era.

In the immortal traces, this trace of immortal characteristics is hidden, and Lin Yi is now staring at these things. The only thing that is of great use to one's own immortal body is these, which can actually make up for each other, and then evolve the ontology.

The immortal body has evolved again, and the powerful recovery power has made Lin Yi, who was originally unbearable, suddenly relaxed. Because, there is no longer any threat to the instinctive counterattack of the human immortal body, and the next thing is the moment to speed up the comprehension.

He feels very lucky, and it can be said that he has gained a lot from such an opportunity. Lin Yi felt that even if he didn't have anything else to harvest when he came to the Immortal Land, just this time was enough.

In the blink of an eye, ten days have passed, and Lin Yi has never been able to go further, and there are difficulties in comprehension. The Immortal Gu Dao is not so easy to comprehend, and the only consolation is that it has obtained the immortal characteristics and improved the immortal body.

Call!

On this day, Lin Yi woke up from his comprehension and spit out a breath of filthy air. His breath has reached its peak, and the spirit of the whole person is a little different, if it used to be an unsheathed sword, now it is like a supreme sword with a sharp edge.

"This Immortal Ancient Dao is mysterious and profound, I can't do it if I comprehend it like this, but it can give me countless inspirations and greater understanding, and it will be easier to create my own Dao in the future."

Lin Yi pondered here, while looking at the immortal body in front of him, he suddenly remembered something in his heart, that is, the remnant soul of the demon immortal who was suppressed by himself in the sea of knowledge.

"The flesh of a human immortal is priceless, so is the remnant soul of a demon immortal the same?" Lin Yi suddenly had a thought.

He wants to improve his own primordial spirit, and the ability in the body of the human immortal to comprehend the physical body, compared to the immortal body, but the remnant soul of the demon immortal is the demon immortal of the immortal ancient era, and his own soul is different, and he has the opportunity to improve his primordial god level.

Just do it when you think of it, Lin Yi instantly put away the human immortal body, and then crossed his knees here, his mind entered the sea of knowledge, ready to peek into the supreme mystery of the demon fairy soul. (To be continued.) )
