Ignoring what was happening next to him, Li Shu only focused on his own movements and the small weekly movements within his body.

It is now the fifth time to perform the Small Weekly Breathing Exercise.

The speed under water is twice as fast as above water.

According to Li Shu's guess, it is possible that the pressure in the environment can directly drive the speed of the air that is compressed in the body.

In this way, as long as you are in a place with more intense atmospheric pressure, theoretically speaking, the small weekly breathing movement in your body can be further accelerated.

This is just Li Shu's conjecture. He has not gone through rigorous practice and obviously does not dare to draw conclusions.

So far, I have only experimented in water, and generally within three meters of water.

With Li Shu not very proficient in physics knowledge, he analyzed it through his own rough theory.

He didn't know whether it was right or wrong. This is what Li Shu thought. According to the pressure in the water, generally speaking, through conversion, plus the original atmospheric pressure.

The pressure in water is approximately equal to two atmospheres.

And it's still not too deep in the water.

In this way, Li Shu has every reason to believe that he also has Qi in his body, as long as the pressure around his body or the atmospheric pressure becomes higher and stronger.

Then if the Qi of Xiao Zhou Tian's breathing movement in your body is squeezed and stimulated, the speed of Xiao Zhou Tian's breathing movement will naturally be much faster.

The water pressure within ten meters, that is, the pressure exerted by water on your body, can be roughly equivalent to the intensity of two atmospheric pressures.

Therefore, it is most likely that for this reason, the small weekly breathing movement in Li Shu's body can obtain such a positive speed feedback.

The running frequency of Xiao Zhoutian's breathing movement is greatly accelerated, which is twice the speed under normal atmospheric pressure. It is reasonable to think this way.

In fact, this idea had long been in Li Shu's mind, but he had never had a good opportunity to put it into practice.

As we all know, water pressure is directly and closely related to the density and depth of water. As long as the water is deeper, the pressure of the water will become stronger and stronger.

According to theory, in normal water, every time the water depth increases by 10 meters, the water pressure will increase by 0.1mpa.

0.1mpa is approximately equivalent to the intensity of one atmospheric pressure.

In other words, if Li Shu wanted to obtain three times the respiratory movement rate of Xiao Zhoutian, he would have to be in water at least ten meters deep.

This condition alone made it difficult for Li Shu.

Where can I find a place with ten meters of water?

Go to the river or the sea?

Finding such a place may not be the biggest problem, but the biggest problem is that Li Shu doesn't know whether his body can withstand such strong pressure for a long time.

Generally, divers have to dive to depths and areas much greater than this depth, but don't forget that they have not only received professional and systematic diving training.

And most importantly, they have a complete set of professional and expensive equipment.

Oxygen bottles, diving suits, etc.

These things can greatly reduce the squeezing of the body caused by water pressure to form a good buffering effect.

Generally speaking, this kind of professional diving suit needs to be purchased through some special channels, and it is not very possible for normal people to come into contact with it.

And even if you can buy it, it's expensive.

There are also some conventional diving suits on the market, which can buffer some of the pressure in the water.

But Li Shu thought about it carefully. If he used this thing, wouldn't it be a waste of time?

Originally, one's own small weekly breathing movement needs to increase its speed through the pressure of the surrounding environment on itself.

In this way, the role of the wetsuit is to reduce the pressure of water pressure on the body.

If you say this, the promotion effect of your own small weekly breathing exercises will be greatly reduced.

This is not what Li Shu wants.

However, what Li Shu is worried about now is that even if he performs the Small Zhoutian Breathing Exercise at three times the rate of the Small Zhoutian Breathing Exercise, seven times of Small Zhoutian Breathing Exercise will still take a lot of time.

The existence of the diving suit undoubtedly weakened Xiao Zhoutian's breathing movement. Without the diving suit, would he really be able to withstand the intensity of three times the atmospheric pressure after staying 10 meters underwater for so long?

And because of oxygen breathing, it is very likely that you will need to get an oxygen bottle yourself.

And if you don’t have a complete set of equipment and go deep into the water rashly, there will be many potential threats.

This threat has the potential to easily take someone's life.

Don't look at how tenacious a person's life is. In front of nature, he is just an ant.

Under nature, all food is nothing but dust and gravel, let alone this world.

Even if he is in the world, he is extremely small, as if he is nothing. What if he is in the solar system, the Milky Way, or the universe?

Perhaps the entire human existence is just dispensable, and may not even be qualified to become dust.

Li Shu is just an ordinary person now. He has not even stepped into the extraordinary. Even though his physical fitness is outstanding among the same people, he can dive deep into the water at will, and he is still considered a "rookie".

Such a crazy action must be dangerous.

Putting aside this idea for the time being, Li Shu felt that it was too early to think about this now.

First of all, my mental strength is only enough to complete seven small weekly breathing exercises.

Now, even if it is doubled, or doubled, or even tripled, the speed is the same.

Because after a cycle of seven small weekly breathing exercises, you have to use it for a period of time to recover your mental strength.

Only after the mental strength is restored can you be fully prepared to complete the small weekly breathing exercise again.

And it is a cycle of seven small weekly breathing exercises.

So judging from the current situation, saving a little time will not have much promotion effect on yourself.

At least until Li Shu's mental strength can support the completion of two or even three times of seven small Zhoutian breathing exercise cycles at one time, at this time, he can do his best to increase the speed of Xiao Zhoutian's movement.

Only then can the advantages of Xiao Zhoutian breathing exercise be maximized and the benefits achieved maximized.

Completing multiple small weekly breathing exercises in a short period of time will undoubtedly bring great benefits to Li Shu's body.

Thinking about it, thinking about it in my mind, time passed slowly.
