"It's nature." The head replied.

Su Lin weighed it for a while, thinking that the real martial arts Daluo Tianzhenjun personally pulled him into the illusion last time and gave him the supernatural power of physical control, presumably to use him as a guinea pig, this time the head of Luo Tianmen is the same, the difference is only that he can't refuse the former, he can only forcibly accept the supernatural power, and the latter can symbolically resist.

However, since Zhenwu Da Luo Tianzhenjun chose himself as a test person, it at least means that he has met the prerequisites required for some difficult exercises, and even Luo Tianzhenjun before he ascended back then is very similar, so he was selected.

And Luo Tianmen's collection of "Mixed Yuan Dao Body" is the immortal method left in the mortal world before Zhenjun's ascension, Zhenjun also practiced back then, as a person who was selected by the true immortal to test the exercise, and the compatibility of this exercise should be very good, and it is not impossible to take a risk.

If the power of this exercise is really as the other party said, all the acquisitions can destroy the Nine Great Immortal Gates, then he is a big step away from the goal of rectifying the Heavenly Rules, from this level, this is indeed a once-in-a-lifetime opportunity!

"I promise you." Su Lin replied.

There was a loud laugh from inside the cave, and then the heavy iron door slowly opened, and a creepy aura wafted out of the gloomy darkness, with a strange power that could distort and affect the mind, stirring everyone's nerves.

Su Lin seemed to feel a new experience that was difficult to describe in words.

"Come in, little friend." A voice came from inside the cave, "Xiaoyou, please close your eyes, lest the old man's appearance affect Xiaoyou's sanity."

Su Lin took a deep breath, pushed Luo Huainan to Tianzun, stepped on the moss-covered stone steps, and walked into the dark hole, he followed the other party's instructions, closed his eyes, and also closed other special visions, and only groped forward in the dark space with his sense of touch.

There was a putrid stench in the air, and there was a sound of reptiles walking along the edge of the wall from all sides, and Su Lin's cheeks inadvertently touched some kind of viscous liquid, he dodged slightly, and after touching it with his hand, he found that it was a very sticky sticky silk.

Based on what Su Lin felt now, this place was not like a cave for retreat and cultivation, but more like an animal's nest, reminiscent of the image of an aging creature, a zombie who had degenerated from a human being into an animal, and was struggling to survive in a harsh environment.

…… The sound of breathing.

Su Lin heard the sound of breathing not far ahead, followed by the sound of iron chains rubbing on the ground.

Why chains? Su Lin didn't understand, wasn't it a retreat? Do you still have to lock yourself in retreat?

In the next second, Su Lin felt something pull his sleeve and gently pulled him forward: "Come here."

It felt like someone pinching the corners of his clothes with two fingers and pulling him forward.

The other party didn't hold his hand, and Su Lin didn't want to touch the other party's limbs, his intuition told him that it was best not to have any physical contact with this old immortal, although he and Taolin Sanren were both Yuan Infants, they were essentially different.

The wriggling sound of reptiles in all directions became louder, as if they were converging towards him, Su Lin walked forward cautiously, stumbling along the way, crossing many obstacles that looked like vines, and following the traction of the corners of his clothes, moving aimlessly.

For a moment, Su Lin even felt that he had entered some isolated space, and the entrance to the cave behind him had long since disappeared, and he couldn't go back.

"It's okay, just move on, I can give you a brief description." Tianzun's voice sounded softly in his ears, startling Su Lin.

His eyelids subconsciously loosened a little, and a pair of soft hands intimately covered his eyes.

Then Tianzun began to describe the scene inside the cave: "An old man, let's not take the appearance of a human being, he is pulling your sleeve with his three-meter-long right hand, and his hand is free to expand and retract like an octopus.

There were many green veins on his back, connecting the four walls of the cave and going deep into the walls, and the transparent vessely walls flowed with a thick green turbid liquid.

His torso was almost hollowed out, and there was a cavity in his abdomen, through which the withered intestines and internal organs could be seen, and the surface was very dry, without a trace of water, and he did not know how to send it into his body

Where did all that green blood go?

The ground was full of dry vine-like things, probably not plants, much like those left over from the atrophy of blood vessels.

There are a lot of bugs, like cockroaches, and you're pretty much in that environment right now."

Su Lin could imagine it, but he knew that if he opened his eyes, what he saw would never be as simple as Tianzun described, Tianzun was just using things that humans could understand to make analogies of the indescribable reality.

But he was still surprised that the head of Luo Tianmen turned out to be this kind of appearance that looked like a critically ill patient, and his body atrophied and needed external infusion to survive, which was contrary to Luo Tianmen's fanatical martial arts and tempered physical atmosphere.

"Little friend, stop here, and turn around." There was a voice from the head in front of him, and the air began to become quite hot, Su Lin knew that he was close to the other party, so he stopped and turned around obediently.

He heard the sound of a box flipping behind him, followed by the sound of pages turning in front of him.

Tianzun: "He put a book in front of you, which is the Mixed Yuan Dao Body."

"Alright, please open your eyes, little friend, and look underground, I have put the secret note at your feet."

Su Lin opened his eyes and saw the scene that Fang Cai Tianzun described to him, there were indeed many vines on the ground with atrophied blood vessels, and there were many insect-like black shadows crawling around in the corners, but the scene he could see was only that, and the head behind him couldn't see it.

At his feet, there is a secret book and an oil lamp, under the dim candlelight, the surface of the secret book is shiny and shiny, and on the cover that is close to the color of human skin, there are four crooked big characters written - mixed yuan dao body.

Su Lin sat cross-legged on the spot and picked up the secret tips on the ground, which was not the touch of paper, but closer to some kind of carefully processed animal skin, soaked with oil, which was beneficial for long-term preservation.

Turning the first page, neat words came into view, but Su Lin didn't know a word, this was a text he had never touched at all.

Just as Su Lin wanted to ask, the voice behind him suddenly sounded: "Xiaoyou just cares about looking, reading word by word, if there is a fate, you can naturally understand it, if you don't have a fate...... Huh."

Su Lin stared at the secret book and began to observe carefully, filling the entire cave with a distorted aura, affecting his reading efficiency, making him can't help but wander, after reading a few words at first, he began to can't tell whether it was the unfamiliar words that made him distracted, or the strange aura that made him distracted.

His thoughts became intermittent, giving him the feeling of napping, and sometimes he suddenly reacted and became conscious, but the pages had turned a few pages, and the oil lamp had half burned, but he had no memory of reading at all.

Sometimes, after a wandering mind, he would find that the oil lamp had been replaced, and the secret that he had read to the last few pages had returned to the beginning, and although he still had no memory, his body had undergone strange changes.

Qi's circulation is blocked, the dantian is slightly cool, the whole body is indescribably unhappy, and even the mood is a little depressed, even if you use the magic power to secrete dopamine and other happy hormones, it cannot be eliminated.

"Tianzun, what happened to me just now?" Su Lin looked at Tianzun, who was sitting quietly beside him.
