PS: Thank you for the reward of 'Half a Pot Trail', running naked all the way, it is your support that gives me endless motivation, and there is a shift in the evening.

At noon, it was pitch black.

Meng Li listened to the occasional ticking sound of water dripping on the stone slab from the depths of the cave, and sat cross-legged on the gravel.

He has a special sense of intimacy with the land and rocks of Mengjia Village, which should be very uncomfortable for others to sit on the gravel ground, but he feels very comfortable when he sits.

Meng Li first sat cross-legged and breathed in, as usual, not after sunset and before sunrise, the growth of internal breath was extremely slow, and it was better than nothing.

However, this time, Meng Li paid special attention to absorbing the mysterious energy into his body from the outside world.

"This should be what Zhao Qi said about the vitality of heaven and earth, so little, so little, no wonder the growth of internal interest is so slow......"

Meng Li suddenly realized that the reason why he had cultivated the technique of breathing and breathing at other times was that his internal breath was growing very slowly—that was because except before sunrise and after sunset, there was very little heaven and earth vitality around him!

Meng Li guessed that only in the period before sunrise and after sunset, the Heaven and Earth Yuan Qi was the most time in the whole day.

"Whether it's specific or not, we'll find out when we try it this evening."

After practicing the technique of breathing and breathing for a while, and sensing the vitality of heaven and earth, Meng Li began to disperse the technique of breathing, and began to mobilize the internal breath in the dantian to start from the surrounding area of the dantian, and consciously injected the internal breath into the cells.

In the past, Meng Li used internal breath to recover fatigue, just letting internal breath flow through human organs and tissues, but this is the first time he has consciously injected internal breath into tiny cells.

When the inner breath enters the cells, it is frantically devoured by the population of cells that seem to have been starving for too long.

Inside the cell, a small part of the internal breath is absorbed by the cytoplasm, most of the internal breath is absorbed by the nucleus, the DNA of the nucleus has undergone subtle changes after absorbing the internal breath, and the genes of the cell are optimized after absorbing the internal breath!

Soon, when the cells in the small area near the dantian did not have enough ability to absorb enough, the internal breath in Meng Li's dantian had been exhausted!

There are more than 40 trillion cells in the human body, but the number of cells in this small area of the dantian is more than a million!

"If this continues, I don't know how long it will take to absorb the internal breath of the entire body's cells, and now there are only more than ten days before the North Central City Competition...... If you have it, why don't you let your right hand absorb the internal breath first, so that you can strengthen an arm in the shortest possible time! ”

Meng Li had a plan in his heart, but unfortunately now that his internal breath has been exhausted, he can only wait until the evening to try again.

Meng Li was not in a hurry to go back, but continued to sit cross-legged and check the part that had just absorbed the internal breath.

In the vicinity of the dantian, these cells and tissues seem to become extremely energetic after absorbing the internal breath.

"Hey, no, listen to what Master Zhao Qi said, the ancients directly integrated the heaven and earth vitality into the body, which is different from the internal breath they just used...... Since he can perceive the Heaven and Earth Yuan Qi, wouldn't he be able to directly use the Heaven and Earth Yuan Qi to integrate into the cells just like the innate realm feelings in ancient times? ”

The more Meng Li thought about it, the more excited she became!

The internal breath that you can use is limited, but the heaven and earth vitality between heaven and earth is infinite!

As long as you can really use the Heaven and Earth Yuan Qi to directly integrate into the cells, there will be a steady stream of Heaven and Earth Yuan Qi for you to use!

"I don't know if it's going to be dangerous, no matter what, let's try first!"

Meng Li thought so, so he continued to sit cross-legged, meditated, and adjusted his state.

In less than a moment, Meng Li adjusted his state of mind to be like a waveless lake.

The technique of breathing and breathing slowly began, and a trace of heaven and earth vitality entered Meng Li's body through guò breath as usual, but this time, Meng Li did not practice them into internal breath, but guided them to the position of the biceps brachii muscle in his left arm, and then injected a trace of heaven and earth vitality into a bundle of muscle cells.

With the entry of Heaven and Earth Yuan Qi, this bundle of muscle cells began to devour Heaven and Earth Yuan Qi frantically, but unlike the internal breath, most of the internal breath was absorbed by the cell nucleus, and only a small part was absorbed by the cytoplasm, and at this moment, the cell nucleus did not absorb the Heaven and Earth Yuan Qi, and all the Heaven and Earth Yuan Qi was absorbed by the cytoplasm.

The nucleus absorbs most of the internal breath and optimizes the genes, while the Heaven and Earth Yuan Qi strengthens the cells but does not optimize the genes.

Obviously, the inner breath is a higher level of life energy than the Heaven and Earth Yuan Qi!

However, even if the Heaven and Earth Yuan Qi cannot optimize the cell genes, it is better than the energy source that continuously strengthens the cells!

At this moment, although the content of the vitality between heaven and earth is extremely low, it is enough for Meng Li to absorb it alone!

As the Heaven and Earth Yuan Qi continued to be absorbed into the body, it was injected into the cells of Meng Li's left hand, and as time passed, Meng Li's left hand was constantly changing, from muscles to skin, bones, and even those fascia, all the cells became stronger after absorbing the Heaven and Earth Yuan Qi!

The density of bones is increasing, the skin tissue is more dense, and the muscle fibers are more tenacious and powerful, Meng Li noticed that his left arm was still much stronger than his unstrengthened right arm!

I don't know how long it took, the entire left arm had initially absorbed the vitality of heaven and earth, Meng Li's heart moved, and he escaped from the inside of the cave to the halfway waist of Li Mountain, in front of the boulder where he often practiced.

The sun was shining overhead, and it was noon.

In the sunlight, Meng Li looked at his left arm, and from the outside, the skin became crystal clear, which was different from the skin of his right hand.

"It feels like my left hand is full of power, as if one punch can shatter everything!"

Meng Li clenched his fists repeatedly, and suddenly there was an illusion in his heart that "a punch is blasted out, I have it in the world", he knew that this was the illusion brought about by the sudden surge in the strength of his left hand.

"In the past, the strength of the left hand was slightly worse than that of the right hand, before that, the maximum fist power of the right hand was about four hundred and ninety catties, and the maximum fist power of the left hand should be about four hundred and seventy, but now the strength of the left hand feels two or three times stronger than the right hand!"

Meng Li was excited, several times stronger than his right hand, wouldn't that be two or three times that of four hundred and ninety catties?

Meng Li estimated that the strength of his left hand now is very likely to surpass a thousand catties!

Meng Li's heart moved, and he almost couldn't help but use the soil to escape home and try it with a fist strength testing machine! Fortunately, he has not lost his mind due to excessive excitement, and at noon, there are many people, and if he uses soil to escape, it is very likely that people will be unintentionally seen.

looked at the watch on his wrist, it was already two o'clock at noon, and he estimated that the little guy should go back from Meng Tiezhu's house after eating with Zhao Qi.

"Tu Dun is definitely not going to work."

Meng Li resisted his excitement and ran down the mountain.
