In fact, the materials science course in the third year of junior high school is not very in-depth, and it also talks about the solidification, deformation and heat treatment of materials, but some talented students have already cooperated with some scientific research groups to study more in-depth things.

So in this class, there are still people who are absent from class...

The materials science teacher is a newly accomplished doctoral student in recent years, in his thirties, but he does not dare to underestimate these junior high school students.

Because what these junior high school students are learning is also what he was still reading seven or eight years ago.

After high school, the learning progress of these students will completely surpass that of doctoral students, and directly catch up with the most advanced materials research direction in China.

This also proves that psychotropic potions are indeed extremely useful, but unfortunately they are produced in too small quantities and are mainly supplied to children.

He spoke very quickly, and he had to finish seven or eight hours of class in one class in the past, but despite this, the students below still showed dissatisfied looks, thinking that he was speaking too slowly!

It's a pity that there is no way to do it, he is not a broadcasting department, and the speed of speech can only be so fast...

Fifteen years ago, the college city was built and began to recruit students, and the first few batches were almost all orphans from various cities in China. They are teenagers who have come out of hardship, so they are generally sensible and studious, and they are willing to persist in their efforts, and they have basically entered the important departments of scientific research and the military industrial system after now.

After they were exposed in the society, although the city was closed, some parents began to be willing to send their children to Jackie Chan, and later there were some scientific research machines stationed there, and large enterprises invested in the city.

After all, graduates are too difficult to grab, and if you build your own school, although you can't sign a training contract, there are always so many graduates who are willing to help...

In the college city, starting with numbers, such as the first and second primary schools, were founded by the state, and some strange names, such as Xu Xiaojiao's Tianyu, such as Miyuan, Tiansen, etc., are all founded by enterprises...

Well, the college also has a very painful rule, the name of the school cannot be the same as the name of the company...

Ten years ago, President Li Shitang removed the slogan that science and technology were the primary productive forces, and began to hang up a new one: efficiency is the primary productive force.

Knowledge that used to take ten years to learn now only takes one year, and problems that used to require supercomputers to calculate for a month or more now only take one or two days, and this efficiency improvement has extended the life span of human beings by ten years in disguise!

Therefore, it is never an exaggeration to say that efficiency is the primary productive force, and this policy can also be used in government affairs, business handling, meetings, speeches...

Well, the speech doesn't count...

Therefore, up to now, China has initially had a set of efficient and honest leadership team...

Well, it's a bit far away in class...

Li Shitang said that he wanted to give weapons, and in the afternoon all military regions had already sent them here in transport planes, and the machine guns, howitzers, and mortars were all in 10,000 units, and they were rusty in the warehouse anyway, and they were all sold to see how much they were worth.

There are also hundreds of missile launch vehicles, all of which are sent to the past, and now there are electromagnetic cannon launchers everywhere on the earth, after all, there are many nuclear fusion nuclear power plants built now, and there is no shortage of electricity on the earth, so the electromagnetic cannon is a powerful and cheap weapon with a long range and high rate of fire directly replacing the missile rocket.

In fact, there is also one of the most direct reasons, whether it is a missile or a rocket, it is all for killing, and the electromagnetic cannon can hit a spaceship...

And on the moon, Ling Shiyu commanded the scientists in his own group from time to time.

"In addition to the core technology, they can give whatever they want, and it will be good for us to get them out of the solar system as soon as possible..."

"Princess?" A message popped up: "The earth said that there will be a luminous machine on the moon..."

The one who spoke was a Turing boy who resembled Sakura Manji, and his name was Xiu.

"Are there any drawings?" Ling Shiyu asked.

Soon the message flashed again, and a large file appeared on Ling Shiyu's light brain.

Ling Shiyu clicked on it, and saw that it was a 3D picture of the front of the moon, with hundreds of small dots emitting light all over it.

"That's all for these instruments?" Ling Shiyu zoomed in on the picture and saw something in the point of light.

Inside was a flat spherical crystal the size of a washbasin, slowly rotating along an inexplicable vertical line, emitting a warm glow.

Is it a magic circle?

Ling Shiyu nodded: "Has the Academy of Sciences evaluated?" ”

"The Academy of Sciences said that they had never been exposed to this form of technology, and they didn't know the principle, so they couldn't judge it normally, but they thought that it should be a system that converts energy into photons, and there is nothing wrong with it, and it won't cause harm to our mothership..."Xiu replied.

Ling Shiyu nodded, thinking to herself.

This Li Shitang is also smart, the sun will disappear, but the Turing family and the earthlings are now grasshoppers on the same rope, so the moon is naturally still there.

As long as the moon is turned into a luminous body, although there is no light and heat, it will not plunge the earth into eternal darkness!

I guess they are doing it to themselves... Ling Shiyu shook her head and agreed, anyway, it's still the honeymoon period, isn't it...

"They agreed..."A soldier guarding the address book came to report, he looked at the "young man" in front of him with reverence, although he knew that this was a middle-aged man who was already in his forties, but he could not help but admire the fact that he could maintain a young state.

Moreover, this man is also one of the highest authorities on the planet.

Agreed!

Li Shitang was a little excited.

This is a good lighting array, but this is only the initial version submitted by the Academy of Magic, and there is only one basic lighting function.

At this time, Li Shitang had more ideas and needed this formation to be realized.

He needs more than just a moon capable of illuminating ...

After all, no one knows if he can escape smoothly, and he is ready to break the boat.

But he broke someone else's kettle, sank, and it was not the ship of the earth.

It didn't take long for news to come from Azer's side.

The heat-resistant formation has been successfully combined.

However, the instruments in the hands of these scientists can only produce a maximum temperature of 6,000 degrees Celsius, and they have tested it at this temperature, and the formation is intact.

But whether they can meet Li Shitang's requirements, they don't know in their hearts, so they need to cooperate with the test on the earth's side.

Li Shitang simply moved away from the transaction screen and let the scientists and magicians study it.

He just stared at his trading point in a daze...

At this time, the trading point had reached as much as 240,000, but he didn't expect that the technology and laws of physics after that would have little value for Ai Zeer or Yunlong Jiu, but a page of "Smiling Proud Jianghu" used to wrap an instrument was worth 200 points!

That's just a rough mention of the power of the Dugu Nine Swords...

At this time, he discovered how valuable the various martial arts fairy tales and magic western fantasy novels on the earth were.

So much so that now even "Dream of Red Mansions" has launched a magical version...

But he didn't dare to use these trading points...

Upgrading to Level 3 requires 200,000 trading points.

But once he uses it, he will lose his invincible luck, 40,000 luck, and he may no longer have the magical ability that he used to refer to...

At that time, the progress of scientific research on Earth will be greatly delayed...

And the crossing is uncontrollable, such as the big tree world, although he has become extremely powerful there, but after returning to the earth, neither the true qi nor the spiritual yuan power can be used...

If you encounter a world with no growth at all, and the proportion of time is extremely cheating, wouldn't it be worth the loss?

So his plan was to start it when the Earth had set sail.
