In 15 seconds, Renault let go.

He did not dare not let go, because at this time the speed has exceeded 420 M / s, less than 200 m from the ground, at most 0.5 seconds will hit the rock, he must seize the time to slow down.

The moment he let go, the gun of light came down from the sky and hit the giant turtle.

At the same time, when the book of thermodynamics turns to page 5, the golden ball representing the first law of thermodynamics appears at the top of the page, the magic power rushes in, the strong golden light shines, and some mysterious change appears on the gun of light.

The light on the surface of the gun of light began to dissipate rapidly. In a flash, it completely dissipated, revealing the bright red body of the gun, then turned dark red, and finally returned to silvery white.

When the temperature of the gun body drops by one point, the landing speed will be one point faster. When the fish gun returns to its original state, its speed will suddenly increase and become a real thunder.

Heat, kinetic energy!

This is the thermal shift!

In order to maximize the effect of this skill, Renault rigidly heated the temperature of the fish gun to more than 2600 degrees, which was very close to the boiling point of the steel.

Because the more heat, the greater the kinetic energy, the faster the gun.

It took less than 0.3 seconds from the beginning to the completion of a series of magical changes on the fish gun.

Under the multiple effects of gravity, [mindfulness] and [thermal transformation], the fish gun becomes the weapon of heaven''s punishment!

During this period, giant turtle experienced the biggest ups and downs in the "turtle life".

When Renault flew to 5000 meters, the giant turtle could not see Renault. It thought the enemy had left, so it crawled away leisurely.

After climbing more than ten meters, it suddenly smells a strange smell, and the content of the smell is very rich.

There is the smell of the dead. It is the smell of internal organs. It has spent a long time on this island. I don''t know how many people have killed in the courtship competition. I am very familiar with this smell.

In addition, there is another kind of breath. Giant turtle knows that this is the breath of "bipedal beast". It has seen "bipedal beast" several times in the past.

But they are very stupid. They are busy picking up black stones every time, which makes the giant turtle very confused. They don''t have a long carapace, so it''s useless to eat them?

This kind of "two legged beast" is weak, looks very thin, and is generally far away, it is not interested in chasing them.

But now it''s different. Judging from the smell, these "bipedal beasts" are not far away. In order to "drive away" the strange "bipedal beast", the giant turtle spent a lot of effort and just felt a little hungry.

Although bipedal animals don''t have much meat, after eating them, they can at least have a cushion.

By the way, you can vent your anger. The flying "bipedal" is very powerful. The giant turtle has no way to take it, but it can only use the "bipedal" which can "crawl" with two legs to kill as many as possible.

The giant turtle sniffed carefully again, determined the location of the prey, and then quickly climbed to the "bipedal" position with four thick legs.

When Renault fell to more than 300 meters, the excited giant turtle was expecting a good meal and climbed nearly 100 meters forward.

At this time, it suddenly noticed that there seemed to be something in the sky. It stopped and looked up alert, intending to observe.

When the light gun appeared, the tortoise just looked up and saw a strange light ball.

Guangtuan?

The giant turtle was stunned for a moment. In his long life, he saw this strange thing for the first time, which made him very uneasy.

When the gun of light was out of hand, the tortoise realized that the light group was coming at him.

It instinctively felt that something was wrong. In a hurry, it began to mobilize the magic power, strengthen the carapace, and launch the gravity field to surround its body.

It is very confident in its own ability. In the previous battles, it blocked the small stones in the same way in the face of those "tortoises" with amazing speed.

Giant turtle believes that this time, too.

When the gun of light disappeared and turned into a thunderous shadow, the tortoise was shocked.

Because it suddenly found that the gravity field can''t shake the shadow!

How is that possible?

Of course!

Can a bullet weighing only ten grams compare with a fish gun weighing more than 30 kilograms?

The quality gap between the two is as high as 2000 times!

Let''s count the energy.

What''s the kinetic energy of the bullet? According to the kinetic energy formula, which is the mass times the square of the velocity, it''s less than 35000 joules.

What about the fish gun? Its energy is mainly composed of two parts,

the first part is the kinetic energy of heat conversion.

According to the formula of specific heat capacity, when the temperature of steel is reduced from 2600 ℃ to less than 50 ℃, how much heat is released?

Up to 36 million joules![thermal conversion] no lossless conversion is possible. At present, the conversion efficiency is just close to 95%, so the converted kinetic energy is 34 million joules.

The second part is the kinetic energy of the gun itself.

When Renault launched the fishgun, its speed was only 400 meters per second, far less than that of a bullet. However, thanks to its high quality, its initial kinetic energy was also 6 million joules.

After thermal transformation, the total kinetic energy of the fish gun is 40 million joules, more than 1000 times that of the bullet!

What is the concept of 40 million joules?

On earth, the standard of kill kinetic energy in many countries is only about 80 joules. In other words, as long as you hit the unprotected part, 80 joules is enough to cause damage.

For another example, TNT explosives on earth can generate 4.2 million joules of energy per kilogram, and 40 million joules is equivalent to nearly 10 kilograms of TNT explosives, which is a real "explosive" output.

10 kg TNT doesn''t sound like much, but you know, the charge of a grenade is only about 50 grams, 10 kg can make 2000 grenades.

More importantly, the 40 million joules of energy, in a short moment, is all released in a small area. Unlike the explosive explosion, the energy scatters around, and more than 95% of the energy is wasted.

In addition, we can get that the speed of the fish gun is 1150 M / s.

That is to say, after Renault played a game of "reverse heat conduction" and "thermal transformation", the speed of the fish gun suddenly increased by 700 m / S!

Can the giant turtle bear this 40 million Joule gun?

In this world full of magic power, there are limits to any ability. Renault''s mind power is the same as giant tortoise''s gravity control. Its gravity can pull bullets, but it can''t pull fish guns.

Therefore, the giant tortoise can only look at the fish gun in horror, and see the gravity field as if there is nothing, and hit the tortoise shell without moving forward.

Oh, no, because of the angle, it can only see the fish gun breaking through the gravity field, but it can''t see the fish gun hitting the turtle shell.

But the giant turtle felt it.

In the last second of his life, he clearly felt that a tremendous force, a destructive force that can destroy everything, came to him.

Fish gun and turtle shell contact moment, turtle shell, smash!

Even if the tortoise shell has been strengthened by extraordinary force, it is no different from the paper shell in front of the gun of heaven''s punishment. With the impact point as the center, a tortoise shell with a radius of more than 1 meter bursts and collapses in an instant.

Then the internal organs and bones under the shell were smashed!

The giant turtle''s flesh and blood flew around like an explosion. In the blink of an eye, it was covered with dozens of meters of ground.

Then, the fish gun, which completely penetrated the giant turtle, hit the rocks on the ground with a loud bang, shaking the earth and mountains, and rising smoke.

One shot, two seconds!
