"According to our design, we will set up 36 large nuclear fuel thrusters in China, the United States and Australia, and thirty-five smaller thrusters will be placed near each large thruster..."The physicist pointed to the huge earth on the screen: "The large thrusters will use nuclear fusion as the main energy output, and high-energy hydrogen fuel as auxiliary fuel, covering an area of 1080 square kilometers, according to our simulation calculations, it can produce about the earth..." It feels more like a pit placed in the ground, or a gas stove, the surface part is only twelve meters high, but the underground part is fifty meters deep...

The main part of the energy reaction is placed underground, because there is no material that can withstand such a combustion reaction at present, and the earth can only rely on the earth to unload this part of the power.

And these forces that it unloads are actually the driving force that pushes the earth forward.

Although it doesn't feel very good-looking, but after all, it is something that can be used after scientific demonstration, and for the sake of efficiency, the meeting naturally quickly adopted the plan, and then began to mobilize workers to start building...

Well, the construction method is also very rough, 3,888 thruster projects began at the same time, each large thruster has more than 100,000 participants, and more than 300,000 various engineering equipment have participated...

It is a bit unrealistic to say that so many construction machinery are brought in China, but other countries have it.

Almost all of these things are shipped from all over the world by cruise ships.

And because of the improvement of transmission technology, the current equipment is no longer the kind of stupid black and thick that it used to be, such as the giant Z-type produced by the famous domestic heavy industry enterprise Monster Heavy Industry, the price of a machine was 120 million US dollars, and it can complete multiple tasks such as digging pits and bulldozing, cutting and tamping the foundation alone, with high efficiency and speed.

Of course, the output of this kind of machinery is not high, and there are a few large propeller sites on the site, and small people can't divide them.

"You mean, with our current technology, we can push the Earth out of the solar system?" One of the leaders asked suddenly.

The physicist nodded: "It is naturally not possible to rely on the thrust generated by the thrusters alone, but it is still possible to throw the earth out with the help of the force of revolution at a specific time..."

"And how long will it take us to leave the solar system?" Li Shitang asked.

The physicist replied without hesitation: "It should be between 90 and 120 years..."

Li Shitang was speechless, Song Chengxuan was silent, Ling Shiyu patted his forehead and went back to sleep.

"Well, uncle, don't you think it's been too long?" Li Shitang asked: "You must know that our enemy is an extraterrestrial civilization, and it only took them 20 years to get to the earth from somewhere..."

If it takes 90 years to leave the earth, it is better to let go of your scruples and enjoy 30 years...

"One year, it takes me a year for us to leave the solar system, and in ten years we can leave the galaxy completely..."

If you really want to leave the solar system in one year, it is nothing to leave the galaxy in ten years, after all, the solar system is on the edge of the earth, but what about the current technology...

"In fact, the current theoretical speed is already the limit of nuclear fusion power, and we have no way to increase it, if according to the standards of civilization, this is already the speed limit of the third-level civilization...", the scientist replied.

Li Shitang looked at him, his face full of disbelief, if the third-level civilization was at this speed, how did Turing come over?

He looked at Ling Shiyu, but she was not there at this critical time?

"Actually, we have a plan, which is to accelerate the speed of nuclear fusion, so that the energy of the explosion at a point in time is more powerful, so that stronger power can be generated in an instant, but this idea is limited by many things, so it has not been able to develop...," the scientist said.

"What's the problem?" Li Shitang asked busily.

"Materials!" He replied: "We still don't have the right materials to withstand the explosion of nuclear fusion energy at higher energy levels, and I feel that the alloying of the existing metal material combination has come to an end..."

Li Shitang knocked on the table, thought for a while, and replied: "If this is the case, this shouldn't be a problem, we have other ways to solve it, you just need to study a way to burst energy faster..."

He didn't know that this kind of technology was very basic in the hands of a higher civilization, and it was called Pure Burn.

Net combustion can instantly use most of the energy of matter, generating extremely powerful force, which causes the alien spacecraft to produce a rather exaggerated initial velocity when it leaves from a stationary start.

Because of the small size of the spacecraft, this initial velocity can generally far exceed the third cosmic velocity, leaving the Earth and leaving the solar system at the same time.

Therefore, this technology is crucial for civilizations that have entered the interstellar age, and it is known as the crown of the third-level civilization and the cornerstone of the fourth-level civilization.

Although the Earth's current net combustion can only be used on large thrusters, it's also an important step, isn't it...

As for Li Shitang's problem of solving the heat resistance of materials, there is no way to solve it on the earth for the time being, but Ai Zeer has it!

The First Magic Research Institute of Azer, which is an organization formed spontaneously by magicians who realized the importance of magic research after Xitang began to rise, and the magicians here submitted their theoretical designs and experimental plans to the academy city, and then through the quantum computer of the academy city to calculate, and then told the results to these magicians.

This not only saves a lot of magicians' time, but also uses scientific methods to avoid their mistakes in direction or cognition.

But the earth is not calculated in vain, and they often issue tasks for the Academy of Magic to complete.

And these tasks are generally the research and development of various energy arrays.

The most basic example, the enchanted blue trail has changed from the original cosplay prop to a sharp artifact, and various metal materials have been enchanted, and naturally there will be heat, corrosion and oxidation resistance after enchantment...

But this time is different, the materials required for net combustion need to be able to withstand at least tens of thousands of degrees of heat, and even the original enchanted inscription will be burned at this high temperature...

So he needs an inscription that is more resistant to high temperatures, preferably the kind that can withstand millions of degrees, after all, power is such a thing, naturally the wider the range, the greater the room for maneuverability.

This is just the first task, the second task, Li Shitang needs a formation, a formation that transforms energy into light.

"This is a simple, ordinary lighting array," said George Grini, who was still just a great magician.

Li Shitang shook his head: "That's too small, the formation I need is very big..."

George Griney scoffed: "Big, how big can it be, how big is the ball?" ”

Li Shitang shook his head.

George laughed again: "Could it be the size of a dragon?" Are you going to put it in the square? ”

Li Shitang simply said directly: "I need it, your Lancelot Empire is so big..."

George Grini was stunned: "Eh, don't joke with me, talk about it seriously..."

Li Shitang shook his head: "It's so big, you designed it, the light is strong, and it would be nice if there was a candle so bright after 380,000 kilometers..."

George Grini was speechless, these two tasks were more difficult than the previous twenty years combined...

But that's challenging, isn't it...

"But I feel that when the formation is designed, you won't have anything to arrange..."

Li Shitang shook his head: "Aren't there many dragons in your world, as far as I know, dragon crystals are still very big..."

George lit up: "You want to help us slay the dragon?" ”

Li Shitang was speechless: "Haven't you always been helping you..."

George thinks about it, although the earth side does not directly provide weapons, but has been helping to improve the strength of Azer, but it is also helping to slay the dragon in disguise...

Although I haven't killed any of them in the past 20 years...
