Deathly silence!

Even the sound of swallowing saliva is extremely clear.

A circle of police special forces was dumbfounded......

This starts with a similar one.

But there is no way, except for a little less people, less water, less garbage, less front half of the factory, and two less bells in the encirclement, everything is the same as before the two thousand words, and the sense of déjà vu is bursting. Even if Ye Han had already pressed the abort button and stopped spraying.

Well, there is one biggest difference, that is, the boss that frightened them in the previous chapter disappeared directly, and the somersault cloud disappeared for 108,000 miles, either without a trace or in smoke.

What's next?

They looked at each other at a loss, but in fact, Su Xingyan, Chen Lujia and a group of students in the factory were in the same mood.

Su Xing's eyes, star's eyes, star's eyes.

Chen Lu stammered: "You, you, how did you do it?" ”

She has seen the video of the last round of the game, and she knows the power of everything in nuclear leveling, but watching the video and seeing it in person, the shocking feeling is really completely different. Even if the power of Ye Han's cannon is much worse than that of Heping everything......

"Is this thing so, so, so powerful?" Also devouring are the professors and a group of students who have made it themselves.

Hall thrusters, it's really so powerful!

As mentioned earlier, the speed at which the jet of air from the dragon ball gun can almost catch up with the detonation speed of industrial explosives, at about seven or eight times the speed of sound.

But in front of Hall thrusters, it's a fraction.

The jet speed of the Hall thruster can reach 30,000 meters per second, which is close to 100 times the speed of sound! More than ten times faster than industrial explosives, and almost ten times faster than rocket jets!

Because the principle is completely different. The rocket jet is a combustion explosion, and the Dragon Descending Ball Gun is air compressed and then skyrockets, which is not the same level as the thruster efficiency that uses the electromagnetic Hall effect.

What are the disadvantages of Hall thrusters......

It's just that the power is too low.

First, high temperature and high pressure test the material too much; Second, there is a lack of energy in space, the power is limited, and it is useless to make it too big; Third, if it is bigger, it will occupy space and weight, and it will be inconvenient to resettle.

But in Ye Han, all this is not a problem-

The magnetic confinement born from the stellarator is used for nuclear fusion, even if it is greatly modified, the labor and materials are saved, and the magnetic confinement has changed from a ring to a straight cylinder, and there is no big problem in carrying the plasma jet of the Hall thruster.

And energy is even less important!

It's not based on the ground that you can let go of the restrictions and build it casually, after all, this thing is going to the sky in the future, it's essentially an engine and not a cannon......

It is the jet system constructed by Ye Han, just like the previous magnetic rings, which can continuously draw energy from the vacuum energy sea, and is completely unrestricted by the law of conservation of energy.

If you want to spray more ferociously and violently, then thicken the pipe diameter, lengthen the pipe body, and strengthen the magnetic field......

In short, more is beauty, big is good, caliber is justice, and turret is truth!

If there's anything that's not beautiful, it's that since this thing doesn't obey the law of conservation of energy, it doesn't obey the law of conservation of momentum so much.

Don't underestimate what you learned in junior high school physics.

The law of conservation of energy, the law of conservation of momentum, and the law of conservation of angular momentum, although these three basic conservation laws are inferences of Newton's laws of motion, have a much wider scope of application, and are far more basic physical laws than Newton's laws.

Among them, the conservation of energy is introduced by the time translation invariance, the momentum conservation is pushed out by the space translation invariance, and the angular momentum conservation is pushed out by the space rotation symmetry.

It's like how a bicycle can keep going up......

Seems simple, right? High school students do something that can be solved by force analysis.

In fact, it has been more than 200 years since the invention of the bicycle, and for more than 200 years, scientists have been trying to find a more reasonable explanation, but there is still no conclusion, and it is still the topic of a paper that some scientists can bring water at every turn......

Therefore, even if physics is extremely advanced and has reached Ye Han's level, it is not so easy to distort these three conservation laws with intelligence.

Well, back to the point.

To put it simply, don't look at this thing spraying forward so fiercely and empty, God blocks and blows God, Buddha blocks and blows Buddha, and ...... backwards The rope of the jack did not shake a few times.

So, it's no fun to expect this thing to be powered by the engine, unless it's blown backwards and forward.

But if you want to face forward...... There is a lot to be said about the dry man-made lake, the vanishing Kangkla, and the long-lasting pillar of steam that stretches from the ground to the sky like a road to the sky.

Looking at the circle of people who were stunned, Ye Han sighed deeply.

Suddenly, I felt that something was wrong.

One second, two seconds, three seconds......

"You don't even speak? Don't you kick me out of the ring right away? After waiting for a few seconds, Ye Han was stunned and spoke, of course, to the system.

【?-_-?】……

This guy's EQ of 40-1 is really true.

When ordinary people encounter such a thing, which one doesn't endure it and don't ask, and secretly take advantage of it first?

It's just this product, and it's going to get into trouble because things don't meet expectations.

[Can the last round of the game be the same as this one?] The last round was the original world.,It's very troublesome for the plot to collapse.,I don't know how many times this round of the world has collapsed......]

[Besides, labor and management are alive and have souls. Don't use your 40-1 emotional intelligence to figure out labor and management! Who do you insult? 】

（╯'-')╯︵┻━┻

“……”

Insult?

Where is the insult? How insulting? When? How did I not know?

The logic of the system Ye Han didn't understand at all.

But it's very familiar, just like when he was studying abroad, some girls asked him questions, and in the end, there would always be accusations that came out inexplicably.

This guy may be able to say, it's really alive, otherwise the internal logic of a program shouldn't be invisible.

Of course, he still understood the other meaning of the system.

That's the game, he won't be easily expelled from the game, he can make whatever he wants!

Say it earlier! I've been worried about spicy for a long time!

Looking at the police special forces outside, he was still in a daze, and turned around: "Let's continue to work, finish the work as soon as possible, and leave early...... Well, I'll compensate for the damage to this lab. ”

Ye Han said it easily, normal people suddenly encountered this series of things that subverted the three views and shattered beliefs, who could be as heartless as him?

Still stunned and numb, the spirit does not belong.

In fact, what about them? Even the ...... that was blown away

Ye Han was about to greet again, "Boom!" Suddenly, there was a thunderstorm in the sky, suddenly!

No, it was more like the sound of a collision than a crash, like when a laboratory door was slammed open, or when a tank was in free fall and hit the earth, the whole world shuddered and the crowd staggered.

However, there is lightning, and an abrupt stretch across the sky, curved like a dragon and snake, dazzling and dazzling, will not disperse for a long time.

"Boom!" Soon there was a second thunderclap, a second great earthquake, and more lightning appeared, crisscrossing and densely packed.

It wasn't like lightning, it was like a crack in the sky, like a piece of hardened glass about to be smashed.

With the thunder, the sky quickly changed color, from unremarkable cloudiness to cloudiness in the blink of an eye...... No, it was a thick cloud of black and red, as if a volcanic eruption was erupting with ash and magma.

[Tsk, it's really here! I knew that this guy would not be easily convinced......] The system smacked his lips helplessly.

I don't know where a tiger roared, as if it came from the void, but it was as earth-shattering as thunder.

The thick clouds in the sky froze, and the black and red colors quickly faded, turning into a faint golden white.

The next moment, the golden clouds turned into knives and guns, turned into powerful arrows, dense, overwhelming, and slashed at the lightning in the sky that had not dispersed for a long time, and became thicker and brighter!

The sword slashes the thunder, the sword slashes the dragon and the snake!
