"It's raining," Yu Xixi muttered as she sat in a locomotive, listening to the clanging sound outside.

"Mom, let's go back..."Li Xinyi looked at the dark rain outside worriedly, this time it was not water at all, but metal beads!

Under the high temperature of the hydrogen bomb, the battleship of the emperor was sublimated almost instantaneously (the solid state directly changed to the gaseous state), but when the temperature dropped, these gaseous metals naturally condensed into perfect round beads in space, and then fell due to the gravity of the earth.

At this time, there are also many people on the surface who take advantage of the rising temperature outside to come out to see the scenery.

Although, there is no scenery anymore, only the soil and rocks of various colors can be seen.

This is the masterpiece of the antimatter bomb.

Although the material of the locomotive is the latest achievement of the Academy of Sciences, because it is his mother who is sitting in the car, Li Xinyi still can't help but worry, for fear that the metal rain will penetrate the car.

Yu Xixi nodded and let out another sigh.

The once lively and cheerful girl has now become a graceful and luxurious old lady, and the innocence of the past has been erased by time, leaving only the tranquility and tranquility that belong to the years.

"He's been gone for a long time..."Yu Xixi said suddenly.

Li Xinyi was silent.

His father, Li Shitang, he doesn't know how to describe it.

One of the lucky ones who got the trading system? An eloquent leader? Or is it an eternally young old immortal?

If he would be embarrassed to be considered a brother when he went out with his father in the early years, now that he goes out with his father, it is estimated that outsiders will think that he is the father and Li Shitang is the son.

For many reasons, their father and son have not seen each other for a long time.

And they all have very valid reasons: too busy with work, too busy with research, saving the earth, fighting aliens...

Fortunately, Li Xinyi and Li Jinli have a good relationship with the father and son, and their Li family finally didn't make such a joke about family discord.

But now, Li Jinli, who joined the army, rarely goes home.

In general, their family lacks some perfection compared to ordinary people...

The full moon in the sky suddenly shone brightly, and countless people wearing thick clothes and anti-load clothes walked out of the underground base to enjoy this round of moonlight made by people.

Just like people did countless years ago.

Today, if you count according to the old calendar, it is already the Mid-Autumn Festival...

Forty years ago in the Mid-Autumn Festival, Yu Xixi fell drunk in Li Shitang's arms and was carried back to the barracks by him.

Forty years later, she's no longer a drinker.

And where is Li Shitang...

————

The identity of this old man who guards the door is a bit unusual, he is a former teacher of the imperial family.

He has experienced too many things in most of his life, and he also understands the decline process of the emperor best, as well as the pride of the past.

Therefore, even if he is going to perish now, he wants the emperor to have a decent death, and not be destroyed by the crazy people themselves in the riots and disasters.

It's a shame...

"I, I'm this..."Why does Li Shitang feel so weird, his original plan was to find the earth, and after obtaining the technology of this civilization, he will end this civilization by himself, but if he becomes the king of this civilization, how can he start?

It is true that hateful people must have pity, and the old man's reclamation made him a little moved.

"I'll tell you the truth, uncle, in fact, I am the leader of the civilization that fought with you, I can't wait to destroy you, how can I help you get through the difficulties?" Li Shitang simply had a direct showdown.

The old man stayed for a long time, pointing at Li Shitang, you, you have been stunned for a long time, but you didn't say anything.

"The purpose of my coming is very simple, I can't find the earth, you open the door of the radar room and help me find it, I'll go..."

He couldn't do it himself, and he felt guilty when he thought about it.

The old man looked at Li Shitang, thought about the current situation again, and weighed the gains and losses...

"Do you want the technology of the emperor?" The old man asked.

Well?

Li Shitang turned his attention and looked at the old man in surprise.

"Emperor Luo's knowledge base, the key is in my hand, but if you want, I can give it to you..."The old man said: "Whether you are from the earth or not, I just ask you to help us Emperor Luo..."

"Our technology must be very useful to you Earth," the old man said.

Li Shitang was silent, there is no doubt that the emperor is more advanced than the earth, and he also knows that there are scientific and technological differences between the two civilizations, so there must be something to learn from.

"I agreed," Li Shitang replied.

Without waiting for the old man to show a pleased smile, Li Shitang said again: "However, I want to see sincerity first..."

The old man nodded, took out an electronic screen and handed it to Li Shitang.

"This is a list of our emperor's technologies, you can see which ones you need, and then I'll send you one every month..."

Li Shitang took it and swept it, and dense information poured into his mind.

Layered infiltration technology, strong ionization reset technology, strong laser refrigeration, high-precision atomic clock...

There are some that the earth has, and there are a few that the earth does not have.

And Li Shitang found that if these parts that are not available can be obtained in Huaxia, then many science and technology will have a qualitative leap.

For example, micro and nano protective clothing, this kind of clothing is made of a material with stable atomic activity and is not easy to change, although the problem of low temperature on the earth cannot be solved, but at least human beings can wear thin clothes.

Another example is molecular material purity stabilization technology, as we all know, the higher the purity of water, the greater the surface tension, if a thin film of water has enough purity, then it is not a problem to block the explosion of a C4 bomb.

But as long as such water comes into contact with the air, it will be mixed with impurities, how can it be used?

The emperor invented a material, using this principle to stretch the material, the material will have a strong ionization with various surrounding molecules, and the final result is that the surrounding alien molecules are unwilling to mix into the material.

After maintaining the purity in this way, the hardness of the metal wrapped in this material has suddenly increased by a notch!

Another example is the sensor-type balance ball, the balance ball control center used in the mecha is usually on the main console, although the programmers have been trying their best to reduce the commands, but to command the mecha to make an action, it is still a huge project.

However, with this technology, the parts of the mecha can be manufactured separately and assembled in modules, and at the same time, the parts can work in harmony.

This not only greatly improves the practicality of the mecha, but also greatly lowers the IQ threshold of the mecha pilot.

Whether the mecha can become the main force of the war in the future may depend on the performance of this technology.

Of course, Li Shitang didn't know that the giant beast mecha of Emperor Luo was actually based on this technology.

Practicality and applicability are always the most basic criteria for whether a weapon can be used on the battlefield.

"I need too much technology..."Li Shitang put down the screen and said to the old man: "If I have one piece a month, I may not see it end until I die..."

Of course he won't die, but the old man doesn't know.

But the old man was not surprised, and he replied, "It doesn't really matter, because I don't have much to live..."

In his words, there is a kind of spirit that after I die, I don't care about his flood... But Li Shitang saw the weakness and helplessness behind his words...

The demise of a great empire finally needs an outsider to help...

"Okay, don't talk nonsense, you hurry up and appease the people..."The old man urged, seeing Li Shitang's grinding appearance, he couldn't help scolding: "You are a king now, you have to have a little bit of a king's momentum, don't be awkward!" ”
