Bright Sword starts with the grenade flat.

Chapter 156 Chapter : Liu Xiu turns into a mermaid
Because the underwater resistance is large, according to the formula of the square of resistance, the resistance encountered will increase exponentially with the square as the speed increases.

Therefore, the slower the speed of the bullet when shooting underwater, the greater the weight of the bullet belt, and the more the shape of the bullet is combined with the shape in the water, the farther its range will be.

This is just like a bullet cannot harm a person less than one meter away, but a harpoon thrown by human power can harm a person several meters or even ten meters underwater.

So the underwater pistol Liu Xiu finally designed was like an extended version of the COP pistol, and the bullets used were the same .45 bullets as the Thompson submachine gun.

However, Liu Xiu only used the bullet casing, and the warhead was changed by Liu Xiu into a short arrow shape with a length of 20 centimeters and a very sharp front end.

As for why Liu Xiu used this COP pistol, it was naturally because only this four-barreled pistol design could hold such a long bullet.

The swimming pool requested by Liu Xiu had people from the New Third Regiment take turns digging for more than a month before it was completed!

"Captain, why did you dig this swimming pool? You're training us to swim!"

Liu Xiu glanced at Duan Peng, who was curious about the baby, and then said:
"Otherwise! Our area is all land, so it doesn't matter! But the plane we fly can't just hang around here! What if the place where the parachute lands in the future is a lake or the sea! Could it just make the pilot choke? Die?"

Duan Peng didn't say anything after hearing Liu Xiu's words. After all, Duan Peng also understood that 99% of the people in their New Third Regiment were from the north, so some swimmers would not drown if they fell into the water. Probably less than ten percent.

Of course, Liu Xiu did not tell Duan Peng that the main reason for letting the soldiers of the New Third Regiment learn to swim was to deal with the American warships seven years later. The pilot falling into the water was just Liu Xiu's superficial reason!

But no matter what, after putting on the bulletproof vest, I am much more powerful than before!

Of course, in order to allow the soldiers of the New Third Regiment to have a good New Year's Eve dinner, Liu Xiu went to the mountains many times to hunt and killed several wild boars to feed the soldiers of the New Third Regiment.

And Liu Xiu also began to train the soldiers of the New Third Regiment in batches for swimming training.

However, the past four or three years have passed like this after Liu Xiu's actions.

With several heavy rains in early summer, the swimming pool Liu Xiu had dug last winter was naturally filled with water.

Although this is still useless! Even if the vital part is hit by a bullet, the game will end.

Although it is rainwater, since there is no industrial pollution, the rainwater in this era will become clear after entering the swimming pool and settling for a day or two.

In fact, learning to swim is very fast. Basically, you can learn to swim in about a week after choking on a few mouthfuls of water. Of course, if you can't learn to swim in a week, then you are not suitable to be a pilot.

At the New Year's Eve dinner in 2003, Liu Xiu was much happier than many soldiers because he had it with his talented and cheap father Liu Qin.

After entering forty-four years, Liu Xiu was one year older, from twelve to thirteen. Of course, what made Liu Xiu very happy was that Liu Xiu's step-by-step explanation and secret strength made Duan Peng and Wei Under the impression of the monk, the two of them finally broke through the barrier and entered the realm of dark power masters.

During this period, Liu Xiu also discovered an interesting phenomenon, that is, the warriors who were beginners in martial arts, that is, the group of warriors who stood up and stood up, actually held their breath underwater for a longer period of time than those warriors who were not beginners in martial arts.

You must know that the average person can hold their breath underwater for only one or two minutes, but those who are beginners in martial arts can generally hold their breath for more than five minutes.

As for Liu Xiu himself, he also tried it. He actually stayed underwater for more than thirty minutes without feeling where his limit was. Because if Liu Xiu wanted to, Liu Xiu could stay in the water for a day or two, let alone more than thirty minutes.

Of course, this wasn't Liu Xiu's sudden genetic mutation into a mermaid or a reward from his savior system that had been silent for several years.

The main reason for this was that Liu Xiu suddenly thought of human skin respiration when he was in the water.

You must know that before Liu Xiu traveled through time, many doctors and health experts said that you should wear less clothes when sleeping so that your skin can breathe freely. This will not only improve your sleep but also keep your skin healthy and reduce the risk of skin diseases.

And now Liu Xiu has reached the state of transforming energy, which means Liu Xiu can control the opening or closing of his skin pores at will.

So Liu Xiu tried using his pores in the water to see if he could absorb the oxygen in the water. Unexpectedly, Liu Xiu actually succeeded in this test.

Liu Xiu was naturally very happy to discover this new skill. After all, from now on, even if Liu Xiu really said that he was a mermaid, who would dare not believe it!

In fact, Liu Xiu has learned that there are several kinds of fish that have no gills and rely on their skin to breathe underwater. For example, the famous tuna breathes through its skin.

Of course, after many attempts, Liu Xiu also found that flowing living water is best. If it is stagnant water, the oxygen in the water will not be enough for Liu Xiu's skin to breathe.

Liu Xiu naturally understood this kind of thing. After all, locking a person in a sealed car without air circulation would suffocate the person to death.

"Oh! Captain, how do you hold your breath so much! Can you teach me!"

The fact that Liu Xiu held his breath for an hour or two or even longer every time also aroused Wei Dayong's interest. Of course, it was not just Wei Dayong. Duan Peng was also staring at Liu Xiu with curious eyes, hoping to hear how to hold his breath. The trick comes.

Liu Xiu could only smile and wave his hands and said:
"It's not that I don't want to say it, it's that you can't learn it even if I say it! Because my breath-holding technique can't be learned until you have the strength to do it!"

"Captain, if you don't want to say it, just say it directly. Why are you using this to fool us! What does this have to do with the level of martial arts? Is it possible that with a high level of martial arts, people can turn into fish and breathe underwater? No!"

"Hey! Duan Peng really made you right. If your martial arts level is high, you can really turn into a fish and breathe underwater. So staying in the water for three hours is not the highest limit for me. As long as I I think I can stay here for the rest of my life!"

At this time, Peng Peng and Wei Dayong were stunned. They did not expect that practicing this martial arts would actually turn them into a new species.

Then Liu Xiu, Duan Peng and Wei Dayong explained how to use the opening and closing of pores to absorb the air in the water.

Of course, since Duan Peng and Wei Dayong have just learned An Jin, they can freely control the pores in the palm of their hands. If they want to achieve the freedom of switching pores on the whole body, they have to continue to practice hard.

Duan Peng and Wei Dayong, who have just entered Anjin, naturally understand how difficult it is to control pores. It is already very difficult for them to control the pores on the palms of their hands. They need to control their whole body in a short time. The pores are still a little difficult.

However, Liu Xiu did not worry about Cui and the others. After all, it was still early, and there were still more than six years before the confrontation with the Mi army!
