The purpose of Director Carson's visit to China is clear.

The first is to strengthen cooperation with China in the field of space, such as talking about the use of the lunar mass accelerator, and so on, and the second is to buy time for the US space industry.

However, the Chinese side does not seem to have left him much room for negotiation, and the White House, although it has great expectations for his visit, has not been able to provide him with more support.

In fact, it can already be seen from the silence shown by the White House on the issue of Guanghan City.

Even with great reluctance, they still had to, or were forced, to compromise on many issues.

California's controlled fusion power plants have pulled the entire West into the pro-China camp, and perhaps the people of California don't like Huaguo's culture and products so much, but they at least hope that the authorities will not offend Huaguo, and it is better to forget about them for a while, as if they didn't exist.

After all, the citizens of Los Angeles have enjoyed clean and cheap fusion energy, and the social development of the entire western region has once again entered the fast lane.

Now let them go back and accept the bad and expensive thermal power and chemical energy, not to mention that the vast majority of people will not accept it, and there is no way to accept it.

That's what society is all about.

It can only be compatible to the next stage forever.

If it's backwards...... Even a small step back can cause very serious problems.

If relations deteriorate and the Chinese withdraw their experts and equipment, even if it is in the national interest of the United States, the consequences will be unacceptable to the people of California and the citizens of the entire western region, and even more so to the politicians who want to get votes from the people......

Overall, the meeting in Shangjing went quite smoothly.

No matter how furious he was in his office, no matter how much he cursed the competitors in front of him in his usual meetings, Director Carson sat here as docile as a sheep, with a humble and personable demeanor, like a politician from a developed country.

This is actually very rare.

People only show their modesty when facing the strong, and when facing the weak, even if they abide by the rules of politeness, the condescending arrogance in their eyes cannot be hidden.

After the meeting, Director Li went to the office of the elders' house with a memorandum of the meeting and reported the meeting to the old man sitting behind his desk.

After listening quietly to his report, the old man's index finger tapped on the table and spoke.

"I'll draw a line for you, and you can talk about it according to this."

Director Li said respectfully.

"Tell me."

"Economic cooperation is welcome, and political compromise is not negotiable."

Director Li looked solemn and nodded.

"I see."

Although it is only a short sentence, the amount of information is not ordinarily large.

The welcome of economic cooperation means that the leasing of the Lunar Surface Quality Accelerator can be negotiated, and part of the excess capacity can be sold to international customers on the premise of meeting its own transportation needs.

There are also the construction of public facilities in Guanghan City, the supply of daily necessities and consumer goods for the residents of Guanghan City, and Huaguo has no intention of swallowing all of these markets by itself. If they can provide better quality service at a lower price, no one will say no.

As for the political compromise exemption, it is better to understand.

In a simple word, do business honestly, make money together, don't make irresponsible remarks about the problems of the Guanghan Special Economic Zone, everyone can still be friends.

Old man: "Anything else?" ”

Director Li: "There's one more thing. ”

"Say it."

"That Carson wants to bring some lunar dirt from us...... Or a meteorite from the moon to go back as a symbol of our friendship. ”

Hearing this, the old man smiled, and after thinking for a while, he said,

"Friends repay the peach, and I should respect it."

"They have given us 1g of lunar rock specimens before, and we have no reason to refuse such a request. You can go to the Lunar Orbit Construction Committee and say hello to them and ask them to pack a kilogram of lunar soil, and when that Carson leaves, let him take it back. ”

"Also, remember to ask him to bring back another sentence."

"The resources of the moon belong to all of humanity, not to the United States. No country has the right to occupy it alone, but it has the right to exploit and use it, and we welcome any country or organization to join in this quest for the future of all humankind. ”

"As long as everything is in the framework of peace."

"As long as they understand the truth of seeking common ground while reserving differences."

……

Jinling.

Zhongshan International's villa.

Lu Zhou, who was sitting in the study, was playing with the new toy he had just gotten from the previous system mission.

It was a black bracelet with a similar shape to most sports watches, and even the design of the LED screen embedded in the surface was identical.

However, intuition told Lu Zhou that the materials and technologies applied to that screen were probably not available on the earth. In addition to this, on the side of this bracelet, there are five grooves.

When his index finger lightly touches the screen, five small black metal balls less than 10mm in diameter pop out of the five grooves. These small balls move slowly under the traction of an ever-changing magnetic field and look amazing.

Lu Zhou tried to turn his hand over, or wave his arm, and the five black metal balls moved closely with his arm as if they had recognized the bracelet on his hand.

"It's kind of interesting......"

Lu Zhou tried to pinch one of the small balls with his left hand, pulling it away from the magnetic field above the ring, and then released his hand again. I saw that the ball seemed to be tied by an invisible spring, and the moment he let go, it bounced back like a slingshot.

"Toys for alien civilizations?"

Looking at the black metal ball above the suspended palm, the look of interest in Lu Zhou's eyes became more and more obvious.

The description of it is very vague and does not even give a specific name, but according to his exploration, he has discovered some of the functions of this bracelet.

For example, the most basic, it is the same as other sports bracelets, which can measure heart rate and record time.

In addition, it has one of the most important functions, which is to form a constantly changing electromagnetic field around the bracelet that can control the movement of metal balls.

At the same time, there seems to be a special brainwave recognition device built into this bracelet, which can recognize the received nerve signals, convert them into electrical signals and process them through the built-in chip, and then feed back to the magnetic field control unit in the bracelet, so as to manipulate the movement trajectory of the five black metal balls in the air.

In terms of effect, this phenomenon is very peculiar, as if by magic. As for what it was used for, Lu Zhou couldn't figure it out.

In fact, there is nothing wrong with that.

It's like an alien with no legs, if you get a pair of A cones from Earth, I'm afraid you can't figure out what it's used for.

The only thing Lu Zhou can conclude now is that the core materials used in this bracelet, the design of the electromagnet, and the control technology of the magnetic field have far exceeded the existing technical level on the earth.

But at this moment, Lu Zhou, who was groping for the bracelet, suddenly found a familiar sign on its inside.

This sign he vaguely remembers seeing in a dream......

"Xiao Ai."

The drone floating on the side flew over with a small TV hanging around.

[Is there something going on?] Master. (???? ▽??) 】

Staring at the five metal balls floating in his hand, Lu Zhou thought for a moment and asked, "In your database, is there any information about this thing?" ”

When this order was given, Lu Zhou actually didn't have any hope in his heart.

After all, he had asked similar questions countless times, but he had not received any valuable answers.

The only thing he could conclude now was that Xiao Ai was probably the intelligent navigation program on the spaceship that Jialan Civilization had sent to the center of the galaxy at the end.

However, it is a pity that the memory of the previous universe seems to have been completely deleted from its database, leaving no valuable clues-

[Xiao Ai's database, there seems to be information about this thing.] (????????????)???? 】

Lu Zhou: "......??? ”

At the beginning, Lu Zhou thought that he had seen it wrong.

It wasn't until he reconfirmed the text on the small TV that he suddenly came back to his senses and immediately asked.

"Get the information about it, all of it!"

[I'll look for it...... (????????????)???? 】

Very rarely, this time Xiao Ai disappeared for a bit of a long time.

Just when Lu Zhou wondered if it had crashed or deserted to play a game, light blue text finally emerged from the small TV.

[Strange...... There are traces in the cache, but it looks like they have been deleted...... Σ(°△°|||) ︴】

[All in all, it seems to be a weapon, and it once belonged to a seemingly powerful officer.] (＠_＠; )】

Lu Zhou: "......?" ”

What the hell is it all about?!

But what surprised him even more was something else.

If it weren't for Xiao Ai's expression problem, then it probably found that in its "memory", there seemed to be traces of something being deleted.

But then again, does there really such a thing as "memory" exist in artificial intelligence? And can this kind of memory exist separately from the hardware?

Just as Lu Zhou was thinking about this question, another line of text appeared on the small TV.

[Or, master, give it a try and use your imagination or something...... Shoot it in a certain direction? (°ー°〃)】

Imagination?

Weapons?

Launch out?

Staring at the five metal balls wrapped around the palm of his hand, Lu Zhou fell into deep thought.

Suddenly, his heart moved, as if he had thought of something, and he quickly looked at the vase by the wall.

"If it's a weapon......"

His attention gradually focused on the flower pot, although he knew that he might look a little middle-two, but thinking that there were no other people in the study, Lu Zhou didn't care.

The heart rate index on his wrist began to fluctuate, and he didn't know if it was Lu Zhou's illusion, but he felt the five metal balls floating above his palm begin to tremble slightly.

For a moment, it was as if some trigger had been pulled.

The huge after-force climbed up his wrist and forearm, and before Lu Zhou could come back to his senses, the vase he was staring at burst apart with a "snap".

It's like......

It's like being shot by a bullet,

At the same time, the small metal ball floating in the palm of the hand was missing.

Looking at the deep bullet hole left on the wall, Lu Zhou's eyes finally appeared solemn.

"Magnetic slingshot?"

Or something like that.

After all, he didn't know what to call it, the only thing he could say for sure was that there was probably some kind of controlled electromagnet installed inside the metal ball, and when he "gave the attack command", the electrical energy stored in the energy container was released in an instant and converted into a magnetic field that repelled the bracelet.

The whole ball is like a projectile placed on a slingshot, which is ejected in an instant.

It's just a simple thing in principle, but it actually sounds quite bizarre.

What kind of electromagnet can make a 10mm metal ball shoot like a bullet? Not to mention, it is extremely difficult to integrate electromagnets and control chips into a ball with a diameter of no more than 10 mm.

At least the recoil from his wrist Lu Zhou could feel it, and the magnetic field that drove this thing was probably not small.

Staring at the glass shards in the corner of the wall, he fell into deep thought, and after thinking for a while, Lu Zhou spoke.

“…… Let's clean up this place. ”

Xiao Ai: [Okay, master~]

Let's have a chance to study the structure inside.

For this kind of [sample] that exceeds the level of earth technology, Lu Zhou does not expect to be able to restore all the technology from it through reverse engineering, and reproduce an identical knock-off in the real world.

However, if you look at some of these designs, you may still be able to inspire science on Earth.

For example, more advanced magnetic field control technology.

For example, magnetic levitation technology and so on.

Controlling the drone to fly over and remove the broken glass slag on the ground, Xiao Ai also helped Lu Zhou recover the metal balls embedded in the wall, and used repair foam to clean up the bullet marks on the wall.

Seeing Xiao Ai controlling several drones and sweeping robots to clean up the scene, Lu Zhou took off the bracelet on his right hand and put the five metal balls back in turn.

Just as he was about to put this matter aside, turn on the computer and continue to scroll through the literature, looking for the "big enough research topic", there was a sudden knock on the door at the entrance.

Closing the laptop he had just opened, Lu Zhou got up and went downstairs to the entrance and opened the door.

He originally thought that Wang Peng heard the noise in the room and knocked on the door to see how he was doing, but he didn't expect that it was Senior Brother Luo who appeared at the door.

Glancing at Senior Brother Luo unexpectedly, Lu Zhou asked with a strange expression.

“…… Why did you come from Shanghai? ”

"What you said, I'm also a professor at Jinling University, isn't it normal to come back?"

Looking at the "bright" smile on Senior Brother Luo's face, Lu Zhou restrained the urge to roll his eyes and asked with a sigh.

"Tell me, what the hell is going on?"

"It seems you don't know yet." Luo Wenxuan said with a smile, "There was a call to your office just now. ”

"Phone?"

"Uh-huh, guess who hit it?"

"Who's ......?"

"Royal Swedish Academy of Sciences!"

The moment he heard this name, Lu Zhou was slightly stunned.

At this moment, he suddenly remembered what day it was.

"Is it ......?"

"Hahaha! That's right! Looks like you guessed it! ”

Finally didn't have to play anymore, Luo Wenxuan laughed out loud, even more excited than he won the jackpot, stretched out his arm and hooked Lu Zhou's neck, used his strength to eat, and patted Lu Zhou's shoulder with a confused face.

"Awesome, Senior Brother Lu!"

"Congratulations!"

"You've won another award!"
