There was originally this very special true spirit energy in the heavens and the earth, but unfortunately, it has been continuously consumed since ancient times, and gradually this kind of true spirit energy is not as rich as the original, but gradually rare, and mixed with other dirty air, ordinary people breathe this air only to survive, but they may not be able to feel the true spirit energy in it.

Only those who have very good physical qualifications can perceive those precious true spiritual vitality from these mottled and mixed airs after passing the special breathing method, and store them in their own dantian qi sea and slowly cultivate until they change their physique to achieve the goal of cultivating and immortality!

In fact, this kind of cultivation has been slowly passed down for thousands of years, and I don't want to live in a rich true spirit vitality like ancient humans, not only has a long lifespan, but there are also some people with great ability who have become immortals.

This is the information that Yang Yu got from the old man's explanation, the old man himself was too poor in physical qualifications, and the old man of the Nine Crows forcibly forced him to "pass the knack!" through his own condensed mixed yuan true aura, and he was originally expected to be able to reach the foundation of cultivation, but this was obviously a failure, but because of that "knot", his original body was divided into two knots, but his body was rarely transformed.

Of course, this kind of transformation did not allow the old man to embark on the path of cultivation, but his longevity was also caused by other opportunities around the old man of the Nine Crows, and these things may not be clear to the old man himself.

But after following the old man of Nine Crows for many years, he still understands and knows some things about cultivation more or less, so he can also solve Yang Yu's doubts, otherwise he just relies on Yang Yu to ponder those half-understood words by himself, and I don't know how long it will take to figure it out.

After Yang Yu learned this information, he understood that the old man of the Nine Crows had indeed given him a chance, if he could achieve the result of "Enlightenment" under the small snake in his body that had been transformed into the Mixed Yuan True Aura, it would mean that he would be able to cultivate the Dao, which was of course a very good thing, so some of the pain in his body was obviously worth it now, so he became more and more determined to endure it.

But this kind of endurance has a limit, with his current state, it must be very difficult, every painful encounter makes Yang Yu feel deeply frightened, but every time this pain makes him have to grit his teeth and suffer hard! Because if he wants to give up, it is impossible, the old man of the Nine Crows is dead, and there is no one who can help him relieve this pain!

Yang Yu didn't want to commit suicide yet, he was really dead to the point that he was a hundred, but he promised his parents that if he wanted to live, he would live well, and now that he was a little guilty, how could he easily find death? Besides, Yang Yu was quite afraid of this suicide, his body was only nine years old, and he hadn't lived enough!

But the pain of tearing the body is indeed unbearable, and Yang Yu was afraid of it during this time, because the tearing feeling was no longer outside the body, but ran into the body, and it seemed that a pair of big hands were desperately tearing his internal organs, and the pain was even greater! When the pain was the hardest, he almost wanted to tear his chest open and take out all the internal organs.

Fortunately, in the past few days, the old man's bowl of herbs still played a role, not only to preserve him, but also to gradually relieve the pain, that is to say, this bowl of herbs will not make him so painful to drink!

The old man has been living with the old man of the nine crows, but the master still passed away, Yang Yu's appearance gave the old man's psychology a sustenance, the two of them depend on each other, the old man is also greedy for Yang Yu, Yang Yu is now like this, the old man is also very afraid, after all, this kind of "know-how" he finally gave up, he doesn't know if the master does not draw out that true qi, Yang Yu will die for this, in order to save Yang Yu's life, he also has to do his best.

Sometimes, the old man went out of the cave very early, because among the bowl of herbs fried for Yang Yu, there was a very precious "purple leaf grass!" It is a unique herb in this valley, and it must be picked before the sun comes out for the best effect, if it is after the afternoon, the medicinal effect of that grass is not great!

When the old man was not there, Yang Yu always lay on the bed, holding those ancient books in his hand and reading them again, reading and meditating for a while, as long as it was not when the pain attacked, he could still relax for a while!

During this time, the big black dog sometimes goes out, it used to go out every two or three days, and now it will come back after two or three days when it goes out, but every time it will come back with some wild fruits or small beasts for Yang Yu! It can also be regarded as a way for Yang Yu and the old man to improve their food! When he doesn't go out, the big black dog lies at the entrance of the cave, sometimes basking in the sun, but most of the time he sleeps.

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

On this day, the old man came back from outside very late, and when he brought the herbs to Yang Yu, Yang Yu was surprised to see that the old man had scars on his face and hands, and he couldn't help but exclaim.

"What's wrong with you, old man, why are you hurt?"

The old man smiled and said, "It's okay, when I was collecting medicine today, I found that there was a five-leaf purple leaf grass on the cliff in the west, but I didn't expect to climb halfway and fall from it! Fortunately, I wasn't injured, child!

Looking at the old man's loving eyes, Yang Yu felt that there was a big stone blocked in his chest, the old man was already more than two hundred years old, even if he lived longer than ordinary people, but now he was an old man, and he wanted to watch him climb the cliff to collect medicine alone for himself, he really didn't feel good in his heart.

After such a long period of contact, Yang Yu and the old man have gotten along with each other, under the meticulous care of the old man, Yang Yu finally felt the warmth of his relatives' care again, which made his bereavement slowly calm down a lot, but seeing that the old man was working hard for himself, but he was lying all day, he obviously felt that he was very useless.

"Old man, don't go to collect medicine in the future, it's better for me to go when it doesn't hurt, my body is dexterous, don't take risks!" Yang Yu said.

"Silly boy, the true qi in your body now has begun to fluctuate, although the time of pain has been shortened, but if it suddenly attacks, won't it kill you?"

"Haisheng! The old man can still do it now, you can rest assured, no matter how difficult it is, the old man will let you live! Well, I must let you live well!"

This sentence made Yang Yu's eyes suddenly overflow with tears, this sentence is exactly the same as what his father Yang Fulu said! Thinking of this, Yang Yu suddenly felt sad, and threw himself into the old man's arms with a cry of "old man" in his mouth......
