Even the sound of swallowing saliva was extremely clear.
A circle of police special forces were stunned...
The beginning seems similar.
But there is no way, except that there are fewer people, less water, less garbage, the front half of the factory is missing, and the encirclement is missing two hours, everything is exactly the same as before two thousand words, and the sense of déjà vu is overwhelming. Even if Ye Han has already
Press the stop button to stop spraying.
Well, the biggest difference is that the boss that made them frightened in the last chapter disappeared directly. The somersault cloud disappeared thousands of miles away. It may be without a trace, or it may be disappeared into thin air.
What to do next?
They looked at each other at a loss. In fact, Su Xingmou, Chen Lu and a group of students in the factory felt the same way.
Su Xingmu, Xingmu, Xingmu.
Chen Lu stammered: "How did you do it?"
She had seen the video of the last round of competition, and she knew the power of Hepingzhi, but watching the video and seeing it in person, the shocking feeling was really completely different. Even though the power of Ye Han's shot was much worse than that of Heping...
"Is this thing so, so, so powerful?" Also hesitating were the professor and a group of students who built this thing with their own hands.
Hall thrusters are indeed so powerful!
As mentioned before, the jet speed of the Dragon Ball Gun can almost catch up with the explosion speed of industrial explosives, which is about seven or eight times the speed of sound.
But in front of the Hall thruster, it is just a fraction.
The jet speed of the Hall thruster can reach 30,000 meters per second, which is close to a hundred times the speed of sound! It is more than ten times that of industrial explosives and almost ten times that of rocket jets!
Because the principles are completely different. Rocket jets burn and explode, while Dragon Ball Gun compresses air and then expands it. The efficiency of thrusters using the electromagnetic Hall effect is not at the same level.
If there are any shortcomings of Hall thrusters...
It's just that the power is too low.
First, high temperature and high pressure are too demanding for materials; second, there is a lack of energy in space and power is limited, so it is useless to make it too big; third, if it is too big, it takes up space and weight, making it inconvenient to place.
But none of this is a problem for Ye Han——
The magnetic confinement derived from the stellarator is used for nuclear fusion. Even if it is greatly modified, the labor and materials are saved a lot, and the magnetic confinement is changed from an annular shape to a straight tube. It is still not too big to withstand the plasma jet of the Hall thruster.
questionable.
And energy is not a problem!
It's not that you can build something based on the ground without any restrictions. After all, this thing will go to the sky in the future. It is essentially an engine and not a cannon...
It is the jet system constructed by Ye Han. Just like the previous magnetic rings, it can continuously draw energy from the vacuum energy sea and is not restricted by the law of energy conservation at all.
If you want to spray more fiercely, just increase the diameter of the pipe, lengthen the pipe body, and strengthen the magnetic field...
In short, more is beauty, bigger is better, caliber is justice, and turrets are truth!
If there is anything unsatisfactory, it is that since this thing does not obey the law of conservation of energy, it also does not obey the law of conservation of momentum.
Don’t underestimate the content 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 corollaries of Newton's law of motion, their scope of application is much wider. They are far more basic physical laws than Newton's law.
Among them, energy conservation is derived from time translation invariance, momentum conservation is derived from space translation invariance, and angular momentum conservation is derived from space rotation symmetry. It may seem simple, but its depth is far beyond the understanding of ordinary people.
Just like how a bicycle can survive...
It seems very simple, right? It’s something that a high school student can solve by doing a force analysis.
In fact, it has been more than two hundred years since the bicycle was invented. For more than two hundred years, scientists have been trying to find a more reasonable explanation, but so far there is still no conclusion. It is still the title of a paper that some scientists can easily come up with...
Therefore, even if physics is extremely advanced and reaches Ye Han's level, it is not that easy to distort these three conservation laws with intelligence.
Well, back to the topic.
In human terms, even though this thing sprays so fiercely and emptyly forward, it blows God when it is blocked, blows Buddha when it is blocked, and backward... the lifting rope does not even shake a few times.
Therefore, there is no point in expecting this thing to provide thrust as an engine unless it is turned upside down and blown forward.
But if we want to move forward...the dried artificial lake, the disappeared Konkra, and the long-lasting steam column that stretches from the ground to the sky like a road to heaven, I think there is a lot to talk about.
Looking at the circle of people who were as dumb as a chicken, Ye Han sighed deeply.
Suddenly I felt something was wrong.
One second, two seconds, three seconds...
"You didn't say anything? Didn't you expel me from the arena immediately?" After waiting for a few seconds, Ye Han was stunned and spoke, of course to the system.
【?-_-?】……
This guy's emotional intelligence of 40-1 is absolutely true.
When an ordinary person encounters such a thing, who wouldn't just hold back and not ask, and first secretly take advantage?
This guy will get into trouble because things don't go as expected.
[Can the last round of the game be the same as this one? The last round was in the original world, and it was very troublesome if the plot collapsed. This round of the world has collapsed for countless times...]
[Besides, labor and management are alive and have souls. Don’t use your 40-1 emotional intelligence to speculate on labor and management! Who are you insulting? 】
(╯'-')╯︵┻━┻
"..."
insult?
Where was the insult? How? When? How come I didn’t know?
Ye Han didn't understand the logic of the system at all.
But his words were very familiar, just like when he was studying abroad, some girls would ask him questions, and they would always end up with accusations that came out of nowhere.
Maybe this guy is really alive, otherwise he shouldn't be unable to see the internal logic of a program.
Of course, he still understood the other meaning of the system.
That is this round of the game, he will not be easily kicked out of the arena, he can do whatever he wants!
You should have told me earlier! You have been worrying yourself for so long!
He looked at the police special forces outside who were still in a daze, then turned around and said, "Everyone, let's continue working. Finish the work as soon as possible and evacuate early... Well, I will compensate for the damage to this laboratory according to the price."
Ye Han said it easily. When a normal person suddenly encounters a series of things that subvert their views and shatter their beliefs, who can be as heartless as him?
Still stunned and numb, with no sense of spirit.
In fact, it’s not just them? Even the ones who were blown away...
Ye Han was about to say hello again, "Boom!" Suddenly there was thunder in the sky, coming out of the blue!
No, it was not so much thunder, but more like the sound of a collision, just like when the laboratory door was knocked open, or a tank fell freely and hit the ground. The whole world trembled, and the crowd staggered around.
But there was lightning, a sudden streak across the sky, curved like a dragon and snake, dazzling and lingering for a long time.
"Boom!" Soon there was a second thunder, a second big earthquake, and more lightning appeared, crisscrossing and densely packed.
It's not like lightning, but like a crack in the sky, like a piece of hardened glass about to be smashed.
Following the thunder, the sky quickly changed color, from ordinary clouds to dark clouds in the blink of an eye... No, it was thick black and red clouds, as if a volcano erupted and erupted with volcanic ash mixed with magma.
[Tsk, it’s really here! I knew this guy wouldn’t be easily convinced...] The system smacked its lips helplessly.
I don't know where the tiger's roar came from, as if it came from the void, but it was as earth-shattering as the thunder.
The thick clouds in the sky suddenly condensed, and the black and red color quickly faded, turning into white with a hint of golden light.
The next moment, the golden clouds turned into swords and spears, and turned into powerful arrows, densely packed and overwhelming, slashing hard at the lightning bolts in the sky that had been lingering for a long time and were getting thicker and brighter!
The sword cuts through thunder, the sword cuts down dragons and snakes!
