The entire underground space has been silent for fifty or sixty years. Over such a long time, the old turtles here have accumulated a huge number. If you have time to dig the quagmire here, there will be an old turtle two meters deep below the quagmire, almost every few dozen centimeters.

All the old turtles here are, and the smallest ones are the size of a pot lid. Such old turtles have grown for fifty or sixty years. If you want to find a smaller one, you have to follow this quagmire and flow upward in the stream. There are also turtles that have been born for 10 or 20 years there.

There are many people in the valley now, and the fifth sword also requires the practice of the Second Age Pill, so Yu Shan came here to catch a few old turtles that have been fifty or sixty years old. Let’s try it and see if the Second Age Pill is not easy to refine.

With the attraction of moss, in just a moment, the mud was like a pot being opened. Turtles emerged from the mud, and there were more old turtles around them, wriggling in the mud, attracted by the moss and trying to crawl out.

When the first batch of people climbed ashore, Yushan chose to overturn a few of them, so they could not escape.

After selecting five or six and putting a large bucket, Yu Shan immediately stopped and stopped catching them. Anyway, these old turtles couldn't escape, so they could just catch them enough each time, and too many would be a waste.

On the way back, Yu Shan thought for a while and caught two small ones on the edge of a Yin River. The diameter of these two turtles was only more than 25 centimeters. Such an old turtle was considered an old turtle, but it was only more than 20 years ago.

Yu Shan was about to take these two turtles back for food. As for the six old turtles who were over fifty years old, one of them was taken back to nourish their grandparents, and the others were refining the second-class pill.

He sent three plastic buckets to Chitianfeng in several times. Yu Shan found a wooden stick to carry it and slowly returned to the old Bian family house.

At this time, the fifth knife led a group of people back to exercise. Now they run in the surrounding mountains every day, while exercising breathing, they are also training their body acuity.

Seeing Tang Baobao and Qiu Furong at the end of the team, Yu Shan asked, "How are they?"

Wu Dao smiled and said, "I ran one tenth of the journey, it's pretty good. I've persisted, I'm not a cute baby."

"It's very good. Pay attention to breathing. In the early stage of cultivation, you need to practice muscles, bones, and skin outside and breathe internally. If you can't breathe internally, you can only rely on your mouth and nose to breathe. As long as you grasp the rhythm, the little oxygen needed by your body during running can be easily supplied, and you won't feel so tired." Yu Shan explained at the two women who were breathing heavily.

"I know, I heard that you have been persisting for several years and have to run 12 kilometers of cross-country twice a day. We can hold on." Tang Baobao gasped and waved her little hands. It seemed that she had done enough homework.

"What did you take?" At this time, Mi Xiaoyong also ran back. He was the last one, but his breathing rhythm was not messy, and his performance was pretty good.

"Fish, shrimp and turtles, I'll eat it for lunch today." Yu Shan said with a smile.

"And there are old turtles?" Pang Tong said in surprise.

"Can Xiaodao be made? If we can't do it, let's hire a chef as soon as possible." Yu Shui asked a crucial question. The old turtle is not that easy to deal with, and he knew that Yu Shan must have never dealt with such things.

"What an old turtle? It's so big." The curious baby Tang had already lifted the lid of the bucket and checked the old turtle in the bucket.

"This time I am so willing to bear it? I have caught so many?" Pang Tong asked curiously.

The fifth knife opened his mouth and said, "Most of them are used to refine alchemy, maybe these two small ones are for enjoyment."

"Can you stew turtle?" Mi Xiaoyong looked at the fifth knife and said.

The fifth knife said: "There are flying in the sky, running on the ground, and swimming in the water. There is nothing I can't do. Don't think I'm bragging. I have been following the troops to carry out various survival training in the mountains since I was thirteen or fourteen years old. After so many years, what else can't be eaten into my mouth?"

"You are awesome!" Yu Shan directly handed the bucket to the fifth knife. Since he was so good at cooking, he would hand it over to him.

"This little turtle has been around for more than 20 years, right?" Mi Xiaoyong asked at this time.

Yu Shan looked at Mi Xiaoyong strangely. He remembered that he had never bought turtles at home, right?

So how did Mi Xiaoyong know that this turtle is over 20 years old?

"It's definitely more than twenty years." The fifth knife said with a smile.

Mi Xiaoyong nodded and did not continue speaking.

"What's wrong? Why are you unhappy to eat turtle essence to replenish it?" Yu Shui also found that Mi Xiaoyong was a little depressed, so he said jokingly.

Mi Xiaoyong whispered: "When my father was not dead, my mother bought a turtle. Our whole family ate it, and it was so delicious."

Yu Shan knew what was going on. When Mi Xiaoyong's father died, Mi Xiaoyong was already six years old. Eight years have passed, but he has already remembered it at the age of six. He should have a deep memory of eating turtles.

"Okay, don't talk about the past. If we had such conditions in the past, we wouldn't have let your father go." Yu Shui comforted.

"I know, remember so clearly, probably because after eating turtles that day, my mother never came back." Mi Xiaoyong whispered.

"Do you miss your mother? Do you want me to find it for you?" Yu Shan didn't know what to say.

Mi Xiaoyong glanced at Yu Shan and Yu Shui, and instead smiled: "I don't blame my mother. At that time, my mother wanted to take me and my sister to leave, but everyone opposed it, so, I don't blame my mother if I leave us."

Yu Shan didn't continue to say anything because he knew very well that if a woman in the countryside wanted to divorce, she would definitely not be able to take her children away.

Even if Mi Xiaoyong's father is dead, only his mother is left, his grandparents, and even his uncles and uncles will not let Mi Xiaoyong's mother take them away.

This is the inheritance concept of rural people. As long as there are people, the family will not be considered a family. Therefore, women can remarry, but children have to be kept.

"Okay, let's not talk about this. Do you know how much this kind of turtle costs per pound?" Pang Tong changed the topic.

Mi Xiaoyong immediately spoke, "Of course I know that turtles that have been raised for five years are usually sold for about 90 yuan per kilogram; those that have exceeded 2 kilograms basically have to be raised for more than 6 years, 120 yuan per kilogram.

The 'old turtle' that has been raised for 8-9 years is sold at more than 200 yuan per catty. I have seen a turtle with a 22 pound. It will last at least 110 years and can be worth 6,000 yuan. In these 20 years, it will definitely be sold for more than 1,000 yuan."

When everyone heard this, the child was very resentful and could still know the market price of turtles.

"Do you know why turtles can live for so long? Have you heard of turtle breathing? The snake breathing technique I taught you last time is a good practice to practice breathing. It is because of breathing and breathing that turtles can live for hundreds of years, or even thousands of years." Yu Shan once again shifted the topic to practice.

In fact, there are many reasons for turtles to live long. For example, turtles like turtles have thick shells that can protect their internal organs and reduce water loss. The turtles move slowly and can only climb more than 100 meters in an hour. They consume less physical strength, so their metabolism is also particularly slow.

When the earth is covered with ice and snow, the turtle does not eat or move. Like a snake frog, it starts to hibernate for more than four months to survive the cold winter, so that the metabolism will be even slower.

In addition to hibernation, turtles also have the habit of sleeping in summer. In the hot and arid summer, they lie in a large stone cave to slow down their heartbeat and breathe and avoid this unfavorable environment.

In addition to hibernation and summer hibernation, turtles are usually sleepy. They will take a nap after crawling for a few steps. They have to sleep for fifteen or sixteen hours a day, and their energy consumption is very small.

These are the reasons why turtles live long. Of course, physical fitness is also very important. The turtles' shell is very hard. When encountering foreign enemies, they will shrink their heads, tails and limbs into the shell to protect themselves.

Of course, these are not essential. In fact, the reason why turtles live long is that their cell division algebra is much more divided than that of other animals. Humans generally only have about 50 generations, while turtles can reach 110 generations.

In other words, when human cells divide for fifty generations and can no longer metabolize, they will grow old. The turtle can continue to metabolize. Only when its cells divide again for sixty generations will the turtle gradually age.

In addition, the turtle goes to bed when it’s okay, and it takes a long time for other people’s cells to divide at one time, not as fast as humans, so the life span of the turtle is longer.

Therefore, if a person can live one hundred years old, then the turtle can definitely live two hundred years old. This is the secret of the longevity of turtle.

If you don’t calculate the hardware of the turtle, if you calculate it carefully, the reason why the turtle can live long is that it consumes less. How to reduce consumption?

Slowing the heartbeat and breathing is an important means, and breathing is the key. Of course, sleeping is the method for turtles to regulate their breathing.

When it comes to cultivation, everyone here is interested, and they all talk about their own opinions.

Even Mi Xiaoyong is not ignorant of this kind of thing now. At the beginning, he was forced to practice by Yu Shan. Now, his physical fitness is already very strong. Of course, this is compared with his friends.

And it is because of this that he surpassed his companions and felt pride that he became interested in cultivation.

"If we learn the turtle breathing technique, can we really live two hundred years old like a turtle husk?" Mi Xiaoyong said with his eyes shining. At this time, he didn't know what he thought of. His listless spirit at the beginning has become excited now.

"Of course, you can practice well. Don't say that you are two hundred, you can be eight hundred years old." Yu Shan said with a smile.

"Why do I feel like you are comforting the child?" Mi Xiaoyong muttered.

"Who lied to you? I wonder if Peng Zu lived to be 800 years old?" Qian Xiaohao said with a smile.

Mi Xiaoyong was speechless. It was written in the history book, saying that Peng Zu lived to be 800 years old, and this was really not something Yu Shan lied to him.

However, no matter how you think about such a thing, you feel unreliable.
