One of Wu Yan's feet had just stepped on the Ziyang Pill at his feet, and he suddenly retracted his feet again. As he stood up, there was a sudden change in his body.

Wu Yan had a look of surprise on his face, and hurriedly sat down cross-legged again. Soon after he sat down, he felt that more and more places in his body were escaping a little bit of cool silk.

He was no stranger to these cool things. These are the kinds of energy flows. Although I don't understand why these energy streams have all disappeared just now, and then they appear from all parts of the body, now is clearly not the time to think about these things.

Wu Yan meditated cross-legged, quietly cultivating according to the mental method of the third layer of the nameless mantra, guiding that little bit of energy flow, slowly gathering together, and then slowly retracting the dantian.

This process was slow and boring, but Wu Yan didn't feel it at all. He cultivated with great interest.

Two hours later, all the energy flows in his body converged, and Wu Yan was taken aback. He felt that this flow of energy that had come back together had doubled in size compared to before.

This discovery surprised Wu Yan at the same time, but also had a trace of doubt.

Wu Yan thought about it, and suddenly a bold idea popped into his mind. Once the idea pops up, it can no longer be contained. He stood up and found that most of his injuries had recovered, and to his great delight, he found that he was in better spirits than before.

He glanced at the cave and frowned, feeling a hint of self-reproach for his reckless behavior.

"I'm still not calm enough, that's not going to work. I used to read books, and when I read that those big people who held great power had the calm bearing of Mount Tai collapsing in front of me, I didn't understand it, but now it seems that this kind of bearing is very useful. At the very least, if I had been calm enough, I wouldn't have dropped the bottle, and I should have analyzed why those energy flows were gone. ”

After Wu Yan summed it up to himself, he clenched his fists tightly, and there was some kind of decision and change. He had a relaxed expression on his face. He walked over and found a new small porcelain vase, put all the eleven Ziyang Pills into the small porcelain vase, put them away closely, and then cleaned up the mess in the cave.

After doing this, Wu Yan walked back to the stone where he usually practiced meditation and sat cross-legged on the stone.

Only then did he take out the few pieces of paper left for him by the pharmacist from his arms, found the fourth layer of the mental method, and read it carefully.

There are not many mental methods in the fourth layer, and in less than half an hour, he has figured them all out several times and understood them all.

After adjusting his state, Wu Yan closed his eyes and concentrated, and began to cultivate according to the mental method of the fourth layer.

............

The whole night passed slowly, and Wu Yan sat cross-legged on the stone, motionless.

When the first rays of the morning sun sprinkled into the Yunhai Cave the next morning, Wu Yan faced the east and slowly opened his eyes. A satisfied smile appeared on his face.

"Whew! it's so comfortable!" Wu Yan got up and walked to the south entrance of the cave, facing the rising sun, stretching happily. After cultivating all night and not sleeping or resting, he didn't feel a trace of sleepiness, and his spirit was better and more vigorous than after waking up.

"Finally broke through the third layer. Wu Yan wanted to laugh happily, but he looked at the reckless mountains outside the cave with a calm face, and pressed that hint of laughter in the corner of his eyes.

Wu Yan took out the small bottle containing eleven Ziyang Pills and rubbed it in love. He now has more understanding and emotion about his uncool behavior yesterday.

Be calm, no matter what you encounter in the future, you must learn to be calm. Wu Yan said to himself in his heart.

He's figured it out now. Yesterday he was not dreaming, but going through a life and death test. That disgusting black tentacle monster must have been the God-devouring Gu that the Medicine Sealer had planted in his brain.

That green ball of light should be his divine soul. God Devouring Gu, God Devouring Gu, presumably it is a poisonous Gu that can devour people's souls. Although Wu Yan didn't know why his divine soul was not devoured by the God Devouring Gu, on the contrary, the God Devouring Gu was devoured by his own divine soul, he knew that the purpose of the pharmacist Feng wanted to use the God Devouring Gu to control him, and it obviously failed.

Wu Yan sneered a few times and whispered to himself: "Elder Feng, since you want to harm me, then don't blame me for being unkind to you." I guess you're having a hard time right now, isn't that what the book says about self-inflicted? ”

There is a detailed description of the God Devouring Gu in the "Medicine Sutra". Gu worms are different from ordinary poisons. The lower Gu person controls the Gu in the body, which is nothing more than the mother Gu in his own body to control the child Gu in the body of the Gu person, and then achieves the purpose of controlling the Gu in the body.

There is a sense and connection between the mother Gu and the child Gu. If the Zi Gu dies in an accident, the mother Gu will also be affected by Yan zhòng, and even death is possible. Now, the God Devouring Gu in Wu Yan's mind has been extremely severely damaged, and the mother Gu in the body of the Medicine Master is no better.

No matter where the pharmacist was now, he would inevitably be severely injured by the impact of Mother Gu's injury.

Wu Yan pondered, I'm afraid it won't be long before the pharmacist should come back. The first thing he did when he came back was probably to settle accounts with himself, and even have a showdown with himself.

Wu Yan is no longer the ignorant peasant boy who just arrived in Xiaogushan two years ago. He has learned to think, he has learned to be calm, he has learned how to protect himself.

Of course, he also learned from the pharmacist Feng that he was cold-blooded and ruthless.

Wu Yan has now broken through the third layer and successfully stepped into the realm of the fourth layer of the nameless formula. He felt a great change in himself. This kind of change is not only a physical change, but also a spiritual and temperamental change.

He felt calmer and more calm than before, his mind was more delicate than before, and he was more thoughtful than before.

If the pharmacist is coming back, his situation will definitely become very dangerous. Before he came back, Wu Yan knew that he had to make a thorough deployment, even if he turned his face, he would not dare to do it lightly to himself.

After Wu Yan calculated in his heart, he cleaned up, went down to the bottom of the valley, and after eating at the valley, he rushed into the study of the pharmacist Feng and rummaged through.

He first left the pharmacist in the study a dozen bags of herb seeds that he hadn't had time to plant, and took a part of each of them and put them away. Then he took out more than a hundred taels of silver that the pharmacist had left for him to spare, together with a piece of paper full of words, and handed it to the servants outside the valley, so that they could buy all the items listed on the paper and send them here within three days.

After doing this, Wu Yan took two cloth bags non-stop, began to dig the soil not far from the medicine field, put them into the cloth bags, and transported them to the Yunhai Cave.

Three days later, the two handymen commanded five or six villagers, carrying three large boxes, to the mouth of the valley. Wu Yan opened the three large boxes, checked them one by one, and satisfiedly rewarded the remaining more than ten taels of silver to the two handymen who were quick to do things. Seeing that Le's mouth was closed, Mao Sui recommended himself to carry the box into the two handymen in the Thousand Grass Valley for him, Wu Yan refused with a flat smile, and waved his hand to let them leave quickly.

Looking at the three big boxes, Wu Yan touched his chin and fell into deep thought.
