Chapter 522 Meteorites attack the moon

"Tuk-tuk-tuk."

"Please come in."

Lin Xiao's office at Beijing University.

After hearing someone knocking on the door, Lin Xiao said something without raising her head.

The door opened, and a voice that sounded old but powerful came.

"Lin Xiao, why don't you go out and rest on New Year's Day?"

Hearing this familiar voice, Lin Xiao finally raised his head, and then said with a smile: "Teacher Xu."

The person coming was none other than Xu Ji, his former mentor.

Xu Ji walked next to him with a smile, and looked out the window at the same time. The cold winter outside was eroding people's hearts, but it did not stop people from going out to play. The students of Peking University were enjoying today, which had only begun since the National Day. Some holidays bring smiles to faces.

"There's nothing interesting to see. I admired the scenery of Beijing University when I was a kid, but after staying here for a long time, I no longer feel that way. It's better to stay in the office and do research."

Xu Ji smiled and saw Lin Xiao lowering his head again, looking at the scratch paper on the table filled with various formulas and calculations, shaking his head slightly, and then looking out the window again, "Our society has become so Well, you have to go out and take a look and see what you have achieved."

Lin Xiao raised his head again, took a sip from the tea cup next to him, and suddenly realized that he had not made Xu Ji a cup of tea or anything, and since today was a holiday, his students went out with their friends in twos and threes. After playing, he was the only one left in the office.

As for him, no one is looking for him. After all, everyone now basically knows that he is studying a very difficult topic.

The chief scientist wants to research a topic, so naturally no one dares to disturb him.

Probably only elders with relatively close relationships like Xu Ji could come to him.

He stood up, went to make tea for Xu Ji, and responded: "Of course I can see that society has gotten better. Of course, although it does have something to do with me, it is not so good that all the problems have been solved."

"Oh?" Xu Jilai became interested, "What other problems do you think there are?"

"We humans are not free enough."

"Not free enough?"

"Well, just like we can't leave the solar system yet."

"Uh..." Xu Ji didn't know whether to laugh or cry, and said, "Well, this kind of problem is not something I can study. I am not very interested in mathematics."

"However, you can be considered an outlier among those of us who study mathematics."

Lin Xiao made the tea, handed it to Xu Ji, then returned to his seat and asked with a smile: "Is it possible that the physics community and the mathematics community are still arguing about whether I am a mathematician or a physicist?"

Xu Ji smiled and said: "It seems so. I don't know the specific situation. After all, I haven't attended those mathematics conferences for a long time... Oh, by the way, this year's International Congress of Mathematicians will be held soon, so you should also pay attention. Have you received the invitation letter?”

Lin Xiao opened the drawer next to the table and took out the invitation letter.

"Well, I received it a few months ago, inviting me to give a one-hour presentation."

"Then do you plan to go?" Xu Ji said, "Oh, by the way, can you go abroad now?"

Lin Xiao smiled: "You also said that our society has improved. Although there are still some problems, there is no problem in going to France."

With the current strength of their country, those conspiracies and tricks in the past are basically no longer dared to be used against them.

So there is no need to worry about problems like assassination happening.

Sufficient protective forces will also be arranged around him by then.

Of course, the most important thing is that with Xiaomi here, no conspiracy or conspiracy in this world can be used against him.

Just like the unlucky Secretary of State who was imprisoned, the problems that occurred with his mobile phone were naturally caused by Xiaomi.

Xiaomi can directly control his mobile phone, and then directly hijack all text messages and calls sent to this mobile phone. At the same time, he can also connect the phone, and directly simulate the electromagnetic waves of the Secretary of State's voice, so that the other party will not be suspicious at all.

So as long as these conspiracies and machinations require the use of electronic devices to communicate, they will not be able to escape Xiaomi's "eyes".

Of course, this is just the simplest.

Nowadays, when any electronic device in the world is produced, a program will be implanted by Xiaomi. This program cannot be discovered even by the manufacturer responsible for the production.

Therefore, with such a function, when all electronic devices in the world are updated, they will be completely under Xiaomi's control.

Therefore, now Lin Xiao is basically not worried about anything else in the world that can threaten him. Even if it is a nuclear bomb attack, Xiaomi can turn the nuclear bomb into a piece of useless waste before it is launched. Iron, who makes the nuclear bombs of various countries very high in safety?

"That's good." Xu Ji smiled and said, "Then what kind of surprise do you plan to bring to our mathematical community?"

"I remember the 2026 conference. I had a video meeting with you at the closing ceremony. As a result, you came up with a one-way function that directly falsified the P=NP problem. Will you have to do it again this year? Did you bring us a surprise?"

As he spoke, Xu Ji couldn't help but said: "It's a pity that in the intervening four years, you have been engaged in aerospace. We in the mathematics community are all very sorry."

Lin Xiao smiled: "What's such a pity? There are many talented people in the world, so you can't always keep an eye on me."

"I estimate that your talent is unprecedented and unprecedented."

Lin Xiao waved his hand, then looked down at the draft paper on the table and said, "As long as I solve this problem, I'll go. If not, forget it."

Xu Ji was stunned for a moment, then raised his head and asked: "What you are studying now is the problem you plan to report? I asked you why you didn't do other scientific research during this time, but were at school... Um?"

"Wait! Zeta function...are you studying the Riemann Hypothesis?"

"Yes."

Lin Xiao nodded slightly.

Before, except for the people at Yue Shisi who knew that he was studying the Riemann Hypothesis, no one else knew.

Of course, he did not hide anything. Although the purpose of studying the Riemann Hypothesis is to solve the problem given on the moon monument, but also, the Riemann Hypothesis is the pinnacle of the current world of human mathematics. Once it is solved, it will naturally also be solved. It needs to be announced to the world.

This is an important milestone for the mathematical community.

Of course, it's no wonder that Xu Ji next to him was so surprised.

His eyes were full of surprise, and soon, the surprise turned into happiness.

"Finally, you finally started to study the Riemann Hypothesis. It seems that I can see the solution to this problem in my lifetime."

After saying that, Xu Ji patted his head again and said with a smile: "Oh, look at me, what are you talking about? It seems that this problem will be solved in July this year."

Lin Xiao smiled, not being modest, and said directly: "Probably."

"Hey, I just like how you agreed so straightforwardly. You are worthy of being my student." Xu Ji laughed and said, "It's great to have such a talent."

Then he drank the tea that Lin Xiao had just made for him in one gulp, then stood up and said, "Then I won't disturb you anymore."

"I'll just wait for your good news."

Lin Xiao smiled and said, "Teacher Xu, just wait, but you also need to have a good rest. Don't be so tired today on New Year's Day."

"What a shame, he's only over seventy years old. Why don't you look at your doctoral supervisor. If Professor Serge celebrates his birthday this year, he will be 104 years old."

"Professor Serge..." Lin Xiao was stunned and whispered in his mouth. Speaking of which, he may not have had a good contact with Professor Serge for a long time, as if it was four years ago.

But at this time, Xu Ji said: "Oh, by the way, four years ago, in 2026, I also attended Professor Searle's 100th birthday party, and he even talked to me and said... I sent you a banquet invitation, but you didn’t reply to him or anything.”

"He seems a little angry."

"But he also knows that it's not convenient for you to go abroad. He's mainly angry that you didn't reply to him. It's been so many years, and you guys should have forgotten about it."

Xu Ji waved his hand and said, "No more talk, no more talk, I have to leave."

But Lin Xiao was stunned when she heard what Xu Ji said.

He had never received that invitation letter back then. If he had received it, he would have sent his most sincere blessings to his mentor first, and then explained the reason why he could not go.

He frowned, but he didn't ask Xu Ji, but said, "I understand, thank you, Teacher Xu."

"Um."

Xu Ji waved his hand and left here.

Lin Xiao thought for a moment and finally called out Xiaomi, "Xiaomi, go check and find out where the invitation letter sent to me went."

After a while, Xiaomi brought back the answer.

"After the bodyguard received it, he didn't tell me about it because he was worried that something might happen if I wanted to go to France to attend the banquet?"

After learning that it was for this reason, Lin Xiao fell silent.

Finally he sighed, "Okay, I get it."

Xiaomi hummed and said, "Master, your bodyguards are so ignorant. They did such a thing without telling you. Do you want me to teach them a lesson?"

Lin Xiao said angrily: "Don't mess around with things. There's nothing to say about this matter. They may have done something wrong, but they can still be regarded as... their responsibilities."

"Oh, that's it." Xiaomi said, "You humans are really complicated."

Lin Xiao smiled, "That's because there are no other intelligent beings around you."

"I don't want other intelligent life."

"Okay, okay, you have the final say. Anyway, no other intelligent life will be born on our earth for hundreds of years."

After a few words of coaxing, Lin Xiao let Xiaomi play by herself, while he focused his attention on the corner of the table, where there was a sealed jar with fine sand, gravel, and pebbles inside.

This was exactly the meeting gift that Professor Purcell gave him when he and Professor Purcell met for the first time.

Sighing slightly, I thought that since I was going to France, I would stop by to see Professor Serre.

Of course, he had to solve the problem at hand first. After all, he just said that as long as he solved this problem, he would go to France.

If you don't get it done, you won't be able to go.

Then he lowered his head again and continued his research.

…

The time has come for the Spring Festival.

This year's Spring Festival is more and more festive than before. After all, just the fact that firecrackers are allowed to set off adds a lot of fun to the New Year.

Lin Xiao also returned home to spend the Spring Festival. However, he was thirty years old but not yet married, so he was nagged by his family again. Of course, as the most famous handsome young man in his hometown, he came to give Almost all of the people he dated fell into disgrace.

There's no way around it, this can be considered a headache for him every year.

However, at the same time, there are more than 20 astronauts from China at the south pole of the moon, which is more than 300,000 kilometers away from the earth, and they are carrying out lunar infrastructure work.

Infrastructure maniacs have now gone to the moon to carry out infrastructure construction.

The method of infrastructure construction is to directly use the ores on the moon for construction.

Of course, this is due to their second aerospace plane, the Tianyu.

The Tianyu is a very pure industrial machine, oh, maybe it should be called a space industrial machine. Many of the industrial facilities inside it have the function of industrial production, such as the electric arc furnace that can be used to refine iron ore. There are also equipment that can be used for refining.

In addition, it also has ultra-large 3D printing capabilities, which can directly build various base buildings.

Just like the Tianyu at this moment, it is supported by the YB-1 bracket, and then a large instrument stretches out from below.

The top of this instrument is connected with a seven-degree-of-freedom robotic arm, ensuring the absolute freedom of this instrument.

Under the instrument, a metal powder nozzle and a high-power laser hole are connected, and they are constantly moving on a platform.

It gradually prints out a building by spreading powder layer by layer and laser melting, solidifying and accumulating layer by layer.

This is a rectangular building that looks like a corridor. Of course, it is actually a corridor, a corridor building used to connect two functional buildings.

After it is completely printed and solidified, the track built below it will automatically run and push the formed building to the side. The astronauts on the moon will then combine this building with the one already built on the other side. The buildings of the Guanghan Palace lunar base are connected.

Next, they need to go inside and complete the work.

"Phew! I really didn't expect that after we landed on the moon, we actually started working on the construction site."

After connecting the oxygen pipeline to another building, an astronaut couldn't help but sigh.

"But don't you think this is awesome?"

Another person who was connecting the wires said.

"Think about it, when people talk about the lunar base in the future, they will think of us. That is such a glorious thing."

"You know, this is Guanghan Palace! The moon base! It's not the ordinary buildings on the earth."

The man said again: "But isn't this still the same as a construction site?"

"Then you decide whether to do it or not. No matter how many people want to go to the moon, they can't do it. If you dislike me, I still dislike you." The person who connected the wire rolled his eyes, and then continued to do his own thing.

"Fuck it, why don't you just show off..."

Before the man finished speaking, they suddenly heard an alarm sound coming from the communicator.

Their expressions suddenly changed, and then they looked at their base. The top of the base was already flashing red light.

"What happened?"

As soon as this question came into their minds, everyone's communicators were turned on, and then they heard their commander's voice.

"Everyone, stop what you are doing now and go to the base hall."

"Notice again, now everyone, stop what you are doing and go to the base hall."

"There's something big to announce."

Hearing this, both of them were stunned.

It seems that something important really happened.

Thinking of this, they all had worried expressions on their faces, and then quickly headed to the base hall.

Soon, more than twenty people arrived at the base hall.

Of course, among the first batch of lunar transformation project teams, the three members who stayed on the moon have also left the moon and are not here.

This is because the gravity of the moon is too small. After living on the moon for too long, they all suffered from serious muscle atrophy. In order to prevent their condition from getting worse, they left the moon a month ago and returned. of the earth.

In front of the base hall, their commander was standing at the front. After asking everyone present to line up, the commander said with a serious face: "Everyone, we have encountered a very serious problem."

"According to the monitoring of Tiannian and Tianyu, we found that a group of meteorites flew from that area of ​​Mars."

"The average mass of this group of meteorites is not large. The heaviest one only weighs 10 tons, and the smallest one is about 500 kilograms."

"However, there are a huge number of meteorites, probably more than thirty."

"According to the system's calculations, about ten of them will hit the earth. Of course, the earth is protected by the atmosphere, so there is no need to worry."

"However, what I am saying is that the earth does not need to worry, the only people who need to worry are us."

"Because more than twenty other meteorites will hit the moon where we are!"

"Among them, it is very likely that it will hit our moon base!"

Hearing this, more than twenty team members were stunned.

What?

Crash into their moon base?

They just built a new base!

Of course, although I felt sorry for the new base they had just built, their lives were at stake, so it was obviously best to escape as soon as possible.

So, thinking about it, their commander also wanted to announce this matter.

Sure enough, the commander then said: "The National Space Administration has also received the notice and issued an evacuation order to us."

"but!"

At this moment, the commander said loudly again: "Don't forget our [Skylight] electromagnetic gun!"

"For so long, we have brought thirteen skylight electromagnetic cannons from the earth. Adding in the skylight electromagnetic cannon owned by Captain Zhu Xiong and his friends, we have a total of fourteen!"

"So, our evacuation is for the safety of each of us, but this does not mean that we will not resist. Therefore, before leaving, everyone went to activate the skylight electromagnetic gun. Then, we watched from the earth Now, can those meteorites break through the range of our electromagnetic gun!"

"yes!"

More than twenty people suddenly became excited.

Electromagnetic gun intercepts meteorites? !

Can they do it?
