Chen Yu felt the energy surging in his body at this time, and couldn't close his mouth in surprise. What happened just now was exactly the same as the feeling of breaking through the third layer by cultivating by yourself half a month ago.

Only this time, he clearly felt that the energy in his body filled his whole body, which made him refreshed and lazy at the moment.

Chen Yu couldn't be happy, and immediately calmed down and picked up the formula. He couldn't wait to know what kind of surprises and surprises he would bring to break through the fourth layer.

Chen Yu silently recited the mantra, and the energy in his body began to move. He felt that the mass of energy in the dantian began to gradually spread along the meridians little by little, spreading throughout the body.

Every time, the energy runs on its own, can you let it follow your command, Chen Yu thought about it and tried it. He had just wanted to gather the energy scattered in his body back into the dantian, when something surprising happened to him. Before he could think of what to do, the energy returned to the dantian along the meridians by itself.

"Could it be the command of the mind, this is also amazing......" Chen Yu couldn't help but wonder. In order to confirm his thoughts, he tried to 'direct' the energy from the dantian to the soles of the feet, hands and other parts of the body.

His conjecture proved to be completely correct. Chen Yu commanded the energy in his body back and forth, and he had a lot of fun. After a while, he felt that this seemed too boring and of little substance.

Chen Yu began to think about it, when he sent the energy in his body to his feet, he felt a feeling of lightness in his feet. When he sent the energy to his feet again, he stood up and tried to make a slight leap, but he didn't expect to go straight over the roof.

Unlike the last time he lectured on the street, Li Yin felt that it was to accumulate the strength of his legs to make his body soar into the air, but this time Chen Yu just lightly tapped the ground. And this time there was no sound after landing.

"This energy is amazing..... Chen Yu muttered. However, in order to prevent Hai Lao from discovering his abnormality, he still held back and continued to feel the pleasure of jumping up.

He thought carefully about the last time he broke through the third layer, his hearing and smell senses had reached a level that ordinary people could not reach, so if he sent energy to his ears or nose this time, would he go further than before.

When Chen Yu sent a small stream of energy to his ears, he began to listen carefully to everything in the valley, everything around him was so real. And Taniguchi's faint voice last time, this time it became real.

On the stone tablet at the mouth of the valley, two birds were flapping their wings, but Chen Yu couldn't hear it so really far away. According to Chen Yu's estimate, he can hear at least three miles away now.

So nose, Chen Yu thought about it or forgot it. It's not a good thing to have a very sensitive sense of smell, the fragrance is fine, but if it smells, he should cry. However, if you send energy to your eyes, you will not see farther.

Chen Yu couldn't help but hesitate a little, what if the energy washed out his eyes, he didn't want to be a blind man in a strange world.

Chen Yu thought about it for a while, and couldn't help but feel that he was too worried and cautious. Isn't it okay if the energy reaches his ears, he patted his head and scolded himself for being stupid.

But this time it was Chen Yu's disappointment, no matter how much energy he sent to his eyes, what he saw was still that. Except for being a little clearer than before, there's nothing special. He bowed his head in disappointment.

"Ah, why is my stomach gone?!" Chen Yu suddenly shouted in surprise.

At this time, Chen Yu stared at the egg-sized mist at the dantian and was stunned. He tried to reach out and touch the dantian, but it was still separated by a layer of clothes.

Chen Yu's eyes narrowed as he stared at the mist, only to see a thin white line that was almost invisible to the naked eye, passing through the meridians from it, and then to the back of his head, and finally the final place seemed to be his own eyes.

"Isn't it ......"

As soon as Chen Yu thought of this possibility, he immediately cut off the formula. When the exercises dissipated, the energy quickly dissipated, and everything returned to normal. Chen Yu looked at his whole body, and even pulled open his clothes to look at the dantian, he was still wearing the clothes he was wearing just now.

In order to confirm the conjecture just now, Chen Yu once again sent the unknown energy in his body to his eyes, which was still the white mist the size of an egg, but it was much thinner than just now.

It seems that this energy in my body is able to allow myself to see my body clearly. Later, Chen Yu learned that this was the so-called 'inner view' in the immortal cultivation world.

Chen Yu thought about it, all the scenes in front of him disappeared, he felt a burst of nothingness in his body, when he wanted to mention that energy again, but found that there was no reaction at all, but was very tired, and a trace of sweat oozed from his forehead.

"Oh my God, the energy seems to be gone. Chen Yu couldn't feel any energy in his body, and his face panicked, the hard work of several months would not be in vain, then he really wanted to cry without tears.

"Ah Yu, the injury is almost healed, right? Then let's start cultivating that formula. Hai Lao's voice interrupted Chen Yu's thoughts, and said to Chen Yu in a non-negotiable tone.

Xie Hai Lao cared. The disciple has already recovered, and he was just about to go to practice after resting. Chen Yu saluted to Hai Lao and replied respectfully.

Although he shouldn't have suspected Hai Lao that day, somehow, he still concealed the news that he had just broken through the fourth layer.

Hai Lao nodded, said no more, and turned back to the house on crutches. Chen Yu saw Hai Lao go back, then turned around and thought about what to do with his energy, maybe he could cultivate again.

Thinking of this, he immediately went back to the house to meditate on the luck exercises, and even forgot to take the stool outside the house with him.

.....

After the early morning of the second day, Chen Yu, who had been cultivating all night, once again saw the white mist inside his dantian. He lifted the energy and swam around his body, and the fatigue of the night was swept away.

Of course, the most satisfying thing for Chen Yu is that the energy in his body can be replenished through cultivation, so he no longer has to worry about running out of energy.

I don't know why, Chen Yu wants to have his own energy more and more, maybe it's for self-preservation.

......

Half a year has passed in the blink of an eye.

The early spring sun is not scorching, it is warm. At noon on this day, in front of Chen Yu's door, he learned from Hai Lao to lie motionless on the Taishi chair that Hai Lao often sat on, with a medical book covering his face, as if he was asleep. On Chen Yu's right hand side is a cup of tea that is still steaming.

Since he broke through the fourth layer of mantras half a year ago, he has been cultivating for two months but has made no progress. Whenever Hai Lao asked about the inspection, Chen Yu's face was full of shame.

And Hai Lao checked Chen Yu's progress every half a month, the first two times were fine, although he was a little disappointed, but he still encouraged Chen Yu, this mantra is difficult to cultivate, don't be in a hurry. After the last inspection, Hai Lao's face sank like water, and he went out with a wave of anger.

As soon as he thought of this, Chen Yu felt that the first four layers were because he was too lucky, and Hai Lao was willing to use medicinal materials to assist him in his cultivation, so he could cultivate all the way to the fourth layer. However, that time, he coveted the pleasure brought by cultivation, and he actually used up the medicinal materials that Hai Lao had stored.

In order to avoid Hai Lao's suspicions, Chen Yu suppressed the progress of the exercises until the third layer had just broken through. This is also a new skill he has acquired after breaking through the fourth layer, controlling the amount of energy and how much it is used each time.

Of course, when Hai Lao inspected for the first time, Chen Yu was still very apprehensive. But Hai Lao didn't seem to be anything unusual, which also confirmed Chen Yu's conjecture.

Since four months ago, that is, after Hai Lao's last angry departure, he left a letter the next day, saying that in order to assist Chen Yu in his practice, he was going to find some precious medicinal materials. It can take as little as a year, as much as two years to come back.

Before leaving, Hai Lao also took Wang Mu away, saying that he wanted him to follow the experience. So in the past half a year, the Holy Hand Valley has become Chen Yu's alone. He continued to practice on time every day according to that set of nameless mantras, and when he had nothing to do, he went to Hai Lao's study to read the medical books.

Hai Lao's medical books, he also read seventy-seven-eighty-eight. Even if he went out to open a medical hall to practice medicine at this moment, it was more than enough, but leaving now was tantamount to betraying the family, and he didn't want to bring some unnecessary trouble to Han Yuanxing.

However, for Chen Yu, being bored alone in the Valley of the Holy Hand was secondary, and he was at ease. The hardest thing to endure was the winter in Qingyunmen, where the heavy snow continued, and dark clouds filled the whole day, and he had been hiding in the house.

Fortunately, Hai Lao did not forget him, and before leaving, he sent someone to deliver food on time every day, but he did not starve him to death in the valley.

Two days ago, the weather suddenly improved, the ice and snow began to melt, and the long-lost sun also came out.

I don't know when he began to like to make tea, and many of the precious teas that Hai Lao left in the house for half a year have cheapened him.

After Chen Yu drank tea today, he was tired from reading, so he lay down, but he didn't expect to fall asleep.
