Although Wu Yan was ready to endure the pain, he still underestimated the power of the God Devouring Gu attack.

In the sea of clouds cave, it has already been a mess. The shocking chaotic scene fully illustrates Wu Yan's fury after swallowing the Ziyang Pill because the pain was unbearable.

To be honest, Wu Yan himself didn't expect what the consequences would be if he did this. The description of the God Devouring Gu in the "Medicine Sutra" made him feel too frightened, and the time he swallowed the God Devouring Gu, the pain of the sudden attack of the God Devouring Gu made him unforgettable, and he would not hesitate to take it when he learned that this Ziyang Pill could expel the God Devouring Gu as soon as he could.

Wu Yan was lying on the ground, his face was pale, his eyes were closed, and even his breathing pulse seemed to have stopped.

In his dantian, there seemed to be a fire burning now, and even the energy flow that he had been cultivating for nearly two years had burned dry. The fire, following the route of the nameless mantra in his body, kept flickering all the time.

Wu Yan had now lost his sense of physical pain. He felt as if he had a dream. In the dream, he entered a world of ethereal darkness.

In that dark world, he found himself in a small pale green ball of light, with a world of his own. In that dark world, he swam freely, unrestrained, and at ease.

He swam for an unknown amount of time, and suddenly broke into the territory of a monstrous monster. The monster was a little smaller than his ball of light, but it was very ugly, covered in thin, disgusting tentacles. The monster was entrenched in the dark world of nothingness, as if it were sleeping, curled up like an oval-shaped ball of dark crystal flesh with tentacles.

The arrival of Wu Yan's green ball of light seemed to alarm the monster. The monster's body suddenly flicked and turned into a slender flesh worm covered with tentacles. The disgusting black flesh worm rushed up fiercely as soon as it saw Wu Yan's small green ball of light. The two long tentacles of its head suddenly cracked a slit, and the crack became bigger and bigger, threatening to swallow Wu Yan's small green ball of light in one gulp.

Wu Yan was stunned for a moment, a little scared. The monster saw Wu Yan's small ball of light stunned, and a row of slender tentacles stretched out from the cracked flesh, which wrapped Wu Yan's small ball of light and pulled it into the flesh. Wu Yan was very annoyed by the monster's disgusting tentacles, and he was not to be outdone, he conjured a big mouth and bit the monster's tentacles viciously.

The monster's tentacles were unexpectedly fragile, and after a few bites, the tentacles that were entangled around Wu Yan were bitten off. After the tentacles of the black tentacle monster were bitten off, it retreated again and again, as if it was seriously injured. Wu Yan was unrelenting, he seemed to realize something, chasing the monster and biting constantly. The monster was unwilling to be bitten to death, and twisted around to entangle with the green ball of light.

Wu Yan was furious, and simply turned his mouth full on the ball of light, and each mouth viciously bit the black tentacle monster. The monster's body was like a black crystal, and it didn't die completely after being bitten by Wu Yan, it split into a small ball of flesh crystals, and then turned into more and smaller tentacle monsters.

Wu Yan's ball of light was in this dark world, chasing those tiny monsters to devour. After devouring these small black tentacle monsters, the ball of light grew in a circle.

This sudden battle came and went as fast as it came. The black tentacle monster, which was less than one-tenth the size of Wu Yan's green ball of light, hid in the dark corner for a long time.

The black tentacle monster that shrunk into a little bit became extremely timid and slippery, and no matter how Wu Yan chased it, he couldn't catch up.

Wu Yan's small ball of light devoured the body of a large number of black tentacle monsters, and the ball of light became larger than the original, and it was even brighter. Since he couldn't catch up with the monster now, and the monster couldn't pose any threat to him, he didn't care. He was happily roaming in this dark world that was now completely his, floating, free, and very comfortable.

Wu Yan likes this feeling very much, and even hopes to stay here forever.

A cold chill poured out little by little from somewhere in his heart, and soon flowed through Wu Yan's entire body. Wu Yan was stimulated by this cold chill and woke up from suspended animation.

In the Yunhai Cave, Wu Yan's lying body suddenly sat up. He felt groggy and uncomfortable, and he felt a little swollen. The body is also soft and weak. It was even more painful in the dantian.

All parts of the body seem to have a burning sensation. Wu Yan was shocked, and his mind immediately cleared up a little. He seemed to remember what happened before he fell unconscious.

Wu Yan sat in the cave, his eyes glazed, and he began to realize what was going on with what had happened to him.

It took him a long time before he came to his senses and tried to stand up. But he tried several times, but he couldn't stand up at all. A cold sweat began to break out on Wu Yan's frightened head. He hurriedly sat down cross-legged and checked his body, but this examination made him almost jump in shock.

He found himself now suffering severe internal injuries. From the outside, he didn't seem to have anything wrong, but many of the meridians in his body were burned by the powerful heat flow contained in the Ziyang Pill because he swallowed the Ziyang Pill.

Wu Yan broke out in a cold sweat, quickly adjusted his state, and then began to practice the nameless mantra.

After practicing the nameless mantra for nearly two years, although Wu Yan didn't know what the energy flow of the nameless mantra was, he knew some of the benefits of this energy flow.

This flow of energy was able to repair his damaged body after he was injured.

Wu Yan cultivated according to the third layer of the nameless formula, and he shivered all over, and was a little overwhelmed. The dantian was empty, and he found that the trace of energy flow that he had been cultivating hard for nearly two years was gone!

Wu Yan's face turned pale, a little overwhelmed, and he opened his eyes blankly.

"Why? Why is this happening?"

Wu Yan's eyes were blank, staring blankly at the chaotic Yunhai Cave, and his demeanor was at a loss.

"Is it because of that Purple Yang Pill? I don't know about that pill, so I just took it casually, and then the energy flow that led my cultivation disappeared? It must be like this!"

Wu Yan suddenly took out the small porcelain bottle containing Ziyang Dan from his arms, and the more he looked at it, the more angry he became, so he grabbed it and threw it out. The vial hit the stone wall of the cave with a crunching sound, shattered, and eleven Ziyang Pills rolled to the ground.

Wu Yan was still angry, stood up, raised his foot and stepped on a purple yang pill that rolled down at his feet.
