As soon as the words "iron cloth shirt" came out, Yang Yu almost didn't squirt out!

"What? Iron cloth shirt, where is the golden bell cover? Are you the kind of person who practices horizontal kung fu?" Yang Yu said in a lost mouth.

Shi San said suspiciously: "I don't know, but my father said that this can exercise my body, not only is my body very strong but also very hard! and I am not afraid of heat and cold!"

"So amazing?" Yang Yu was surprised, and couldn't help but step forward to take a closer look at the mound, only to find that the mound was actually composed of some sand of different thicknesses, but the sand was slimy, as if there was something outside, and there was a pungent smell.

Yang Yu asked Shi San what it was, Shi San couldn't tell clearly, saying that his father took him to get some book covers and squeezed out the juice mixed in it, and he said that this was his family heirloom.

It turns out that Shi San's family has always been a hunter, and he has been dealing with wild beasts in the shining old forest all year round, and he has to learn some ways to exercise, one is to enhance the probability of survival in the wild, and on the other hand, it is also very helpful to hunt all kinds of beasts, after all, like Shi San's body and ability now, the bigger beasts are no longer a problem.

Yang Yu once mentioned this matter to the old man, and the old man didn't know about this kind of thing, he also went to observe the black sand pile, but he didn't know anything about it, even if it was in the classics and books in the cave, it was impossible to record this in this regard.

However, the old man mentioned to Yang Yu some things that the old man of the Nine Crows had talked about in the past, that is, among the ancient cultivators, there were some people who specialized in exercising their bodies, and the whole body was as hard as steel, and they cultivated from the outside to the inside, so as to obtain a very peculiar supernatural power, although there are very few people who cultivate the Tao, but once one appears, basically on the day of Dacheng, they can fight against Tianwei alone, so as to break through the boundary and fly away in one fell swoop!

However, this way of refining the body is very difficult, and it is very bitter, it is not something that ordinary people can endure, and it is necessary to endure unimaginable suffering of other cultivators to achieve something, so at the beginning of cultivation, few people will choose this cultivation method, but the way of absorbing the true spiritual vitality into their own body for internal cultivation is simpler and easier.

"If it's not peaceful today, you can't live here with me all the time, one day you will enter the WTO, and I'm afraid that you won't be able to protect yourself!" said the old man worriedly.

"I won't leave the old man here, I will always be with you, I'm not interested in the outside world!" Yang Yu said, his words have completely exceeded the words of ordinary children of this age!

But the old man shook his head with a wry smile and said: "The old man is old, and since the death of the master, I feel that my body is getting worse and worse, and it may not be far from the limit, I just think that you will be lonely if you are left alone, but after Shi San came, I am also a lot more relieved, at least you still have a companion!"

Yang Yu stopped talking at this time, he knew what the old man was worried about, since the two got along, it was the first time he saw the old man so worried, and he was also the kind of home he found back by the old man's side, in his opinion, the old man was like a family, but he was indeed thinking about his future because of the old man's words.

"Elder Servant, if I walk out of here one day, I must study, well, it's best to find a way to cultivate, even if it's a body cultivation like Shi San!" Yang Yu said.

"Well, if you really have this kind of thought, it's not completely impossible, in the Great Jin Dynasty, the place to talk about learning is which Guanglin Academy, if you want to talk about cultivation, you must enter the Xuantian Sect! And I heard that the Guanglin Academy and the Xuantian Sect also seem to be related!" The old man told Yang Yudao.

"Okay, when I'm a little older, can you come with me?" Yang Yu said with a clenched fist.

The old man could only smile bitterly at this, but he didn't refuse Yang Yu either, Yang Yu was not yet ten years old, at least he had to grow up a little longer to face this cold and cruel world alone, but the old man suggested that Yang Yu follow Shi San to exercise in that sand pile, in his opinion, it was indeed a good way to exercise.

Shi San's age is exactly one year older than Yang Yu, ten years old this year, but he is a very experienced little hunter, his father Shi Yan has not been in good health, it may be the root of the disease left by the peach blossom miasma last time, but since taking the antidote pill of the old man, the residual poison in the body has been slowly discharged from the body, and the spirit and body have slowly become stronger.

Regarding Yang Yu's request that he also want to use that black sand pile to exercise, after Shi San asked his father, Shi Yan had no opinion, and personally instructed Yang Yu to exercise!

It turned out that after the whole person was buried in the sand pile again, he still needed to cooperate with a certain breathing method, and after Yang Yu was buried in the sand pile for the first time, he suddenly felt that those rough gravel began to sharpen his skin in an unbearable pressure and way!

Yang Yu's will is very strong, he showed his toughness when he climbed the cliff alone, and he was also worried that Shi San would laugh at him, so he gritted his teeth and endured it, and withstood the grinding of the gravel with the way he breathed!

As soon as his body came into contact with this strange pressure at this time, he suddenly naturally gave birth to some strange force from the bones of his body, and with the grinding and pressure of the grit outside, he quietly squeezed his bone meridians and skin, this change happened quietly, and Yang Yu did not feel the change in his body at all.

After a few hours of exercise, Yang Yu came out of the black sand pile, Shi San couldn't help but show a mouthful of white teeth and laughed when he saw his appearance, Yang Yu was very puzzled, he felt warm but slimy all over his body, very uncomfortable, so he led Shi San to the waterhole in the middle of the valley to clean it, and saw a black-faced boy in the water!

That boy's appearance is very familiar to him, isn't his nose, mouth and eyes his own? But why is it so dark? He looked up at Shi San and immediately understood what was going on, and couldn't help but point at Shi San and laughed, Shi San also laughed with him!

The innocent laughter of two children resounded throughout the valley, echoing throughout the valley basin......

Yang Yu still pulled Shi San, who was unwilling to clean, to wash the black book skin juice on his body, because Shi San had to exercise in the sand every day, it was too troublesome to clean every day, but after he finished cleaning, his true face was revealed, although he was still a little dark, but he was a boy with very beautiful eyebrows and eyes!

The two children played in the waterhole until dark, after which they exercised together in the sand and bathed together by the waterhole, and three years passed in a flash......
