How did you, a prisoner on death row, become an important weapon of the country? Yecheng Gao Weiming

"When I was in the Marine Corps, I did surface gunnery tests and underwater gunnery tests."

Watanabe Ryuichi pointed at the Barrett sniper rifle in Yao Fei's hand and talked freely.

"You should all be familiar with it. Whether in reality or on TV and movies, it has many models. But most of them are 12.7mm in caliber, and the bullet muzzle velocity can reach 853m per second."

"Theoretically, it can effectively kill targets within 2500 meters. Within 500 meters, it can even smash the enemy into pieces."

"But it is not invincible. Even when shooting at underwater targets, its power will be greatly reduced."

"I have done similar experiments before. If you fire a Barrett sniper rifle at an angle of less than 30 degrees, the moment the bullet enters the water, the huge resistance in the water will cause the copper bullet to quickly break into several shrapnel."

"If you shoot at an angle of more than 30 degrees, you can only hit the target at a distance of 70 centimeters."

"If it's farther away, the bullet will seriously deviate from its trajectory and lose all its power within 1 meter and sink to the bottom of the water! The same is true in reverse. For example, if the challenger underwater uses a carbine to shoot at the water surface, the huge resistance in the water will also cause the bullet to quickly lose kinetic energy after flying out of the barrel."

hiss……

As Watanabe Ryuichi was talking, a sound of someone inhaling cold air was heard on the shore.

Sweep Daisinai, so that's how it is.

We all studied physics, but we just didn't usually come into contact with guns and ammunition.

But if we put aside guns and ammunition and only consider the knowledge at the physics level, we will immediately understand.

Yes!

The density of water is 1000 kilograms per cubic meter. What is the density of air?

1.29 kg per cubic meter.

The gap between the two is a full eight hundred times.

The Barrett rifle can fire in the air, but its power will naturally be reduced by 800 times in water.

If we also take into account the initial velocity of the bullet and the resistance in the water, it is not surprising that the large-caliber bullet of the Barrett sniper rifle breaks into countless shrapnel the moment it enters the water.

To sum it up in one sentence...

Whether shooting into the water or shooting out of the water.

The stronger the kinetic energy of a gun, the less powerful it is.

Because bullets cannot break through density limitations, their own materials cannot withstand the strong resistance from water.

To explain it in Long Guo’s words.

Water, as a thing, becomes stronger when it encounters a strong object, and weaker when it encounters a weak object.

When the principle was revealed, everyone breathed a sigh of relief.

That is to say...

Someone immediately exclaimed.

"Mr. Watanabe, in other words, in this challenge, we can shoot at will without hurting anyone?"

Watanabe Ryuichi smiled faintly and nodded slightly.

"In theory, that's the case."

"In fact, I am not the only one who has done this kind of experiment. Military research experts from various countries have long discovered the thorny problem of underwater shooting."

"If there are enemies lurking in the water, are we helpless?"

"No, military research experts have developed an underwater assault rifle for this purpose."

"This firearm has no rifling, which prevents the bullet from spinning at high speeds and increasing resistance in the water."

"In addition, the bullets it uses are made of high-strength alloy, which prevents it from breaking into pieces the moment it enters the water."

"Its shape is also different from ordinary bullets. It is long and thin, about the length of an adult man's palm. It can be fired at a distance of at least 50 meters in water, so it is easy to kill people."

Everyone took another deep breath.

"pity!"

Watanabe spread his hands and said jokingly, "Obviously, the organizer did not provide us with this kind of weapon, and all the ammunition on site is made of pure copper or plastic. It seems that this is their mistake..."

A light laugh sounded on the water's edge.

Everyone seemed to relax all of a sudden.

If we can't cause harm to people from other camps, then there's no need to kill people.

Then just shoot randomly for a while and you can complete this challenge.

It was indeed extremely simple, many times simpler than the Type A card challenge I just experienced.

"Okay, everyone! Time is limited."

Watanabe Ryuichi glanced at the smiles on everyone's faces and continued, "I see you have all chosen your guns, let's go and challenge them."

"We on the shore naturally have a lot of advantages. Be careful not to kill the people underwater."

"As long as you don't shoot the bullet into the water at an angle of 50-90 degrees, there won't be any problem!"

Following Watanabe Ryuichi's words, the crowd dispersed and began trying to shoot at the people underwater.

Da da da……

bang bang bang...

Kang Kang Kang......

For a moment, the swimming pool was filled with gunshots and splashes of water.

After personal experiments, everyone found that the people underwater were indeed unharmed.

This discovery undoubtedly relieved everyone's fear, and they had a lot of fun.

And what about the people in the underwater camp?

After a brief panic, he also discovered that the bullet could not hurt him due to the resistance of the water.

They also raised their guns and fired back, but the bullets were unable to cause any harm to the people on the shore.

For a moment, the whole swimming pool was shaken.

It was clearly a ten-minute life-and-death duel, but it felt like a carnival in a swimming pool.

Yao Fei watched in silence, wondering how could something that we were the first to discover be known to everyone so easily?

"Hmm... Miss, can I get to know you?"

Just as she was stunned, she heard a voice in her ears again.

Yao Fei turned around and saw that it was still the Sakura man named Watanabe Ryuichi, and she smiled.

"It's not very convenient, and I don't think it's necessary."

His attitude was lukewarm, intending to make the other party give up.

Watanabe Ryuichi said, "Oh, Miss, you may have misunderstood. I am not trying to flirt with you, nor am I attracted by your beauty. I just want to get to know you and your underwater companion."

Watanabe Ryuichi simply took another step and got closer and closer to Yao Fei.

Yao Fei trembled all over, and even subconsciously clenched the Barrett in her hand.

"What do you mean?"

"I told you, there's no need for that."

Suspicious by nature, she is wary of anyone outside of the Dragon Kingdom.

Especially in this crazy game, everyone has to be wary of three-pointers.

In fact, in the last challenge, if her boyfriend hadn’t wanted to get to know Zhang Lianhai from Beijing Institute of Technology, she might have ignored anyone.

What on earth is this Ryuichi Watanabe trying to do?

"Oh, beautiful lady! You might as well think about it again."

Click!

At the same time, Yao Fei heard Watanabe Ryuichi's gentle voice and the sound of a gun bolt being pulled.

and many more!

Pull the bolt?

Yao Fei's whole body tensed up, she turned her head instantly, and even made an attacking gesture.

But the other party's words made the girl unable to move.

"Are you really going to reject a man who... has the only shotgun that can kill your loved one, and has a flechette-type slug?"

Watanabe Ryuichi aimed at Huang Feifeng under the water and said seriously.

At this moment, Yao Fei felt cold all over.
