Chapter 1258: Magnetic slingshot

The purpose of Director Carson's visit to China is clear.
The first is to strengthen cooperation with China in the space field, such as talking about the rent of the lunar mass accelerator, and the second is to gain time for the US space industry.
However, Hua Guo did not seem to leave much room for negotiation, and while the White House had great expectations for his visit, there was no way to provide him with more support.
In fact, the White House's silence on the issue of Guanghan can already be seen.
Even with extreme reluctance, they still have to, or are forced to, compromise on many issues.
California's controllable fusion power plant has drawn the entire west to the pro-Chinese camp. Perhaps the people of California do not like the culture and products of the Chinese country, but they at least hope that the authorities will not offend the Chinese country, and it is better to forget They, just when they don'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 track.
Now let them go back and accept the bad and expensive thermal power and chemical energy, not to mention that most people will not accept it, and there is no way to accept it.
That's what society is like.
Compatible only for the next stage.
If you go backwards ... even a small step back can cause serious problems.
If the relationship between the two countries deteriorates, the Chinese will 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 even the entire western region. Unacceptable for politicians who get votes from the public ...
All in all, the meeting in Shanghai was quite smooth.
No matter how wildly thunderous in his office, no matter how he curses these competitors in front of him during meetings, Director Carson sitting here is meek like a sheep, behaves humbly and full of grace, like extreme A politician from a developed country.
This situation is actually very rare.
People only show their modesty when they are facing the strong, and when facing the weak, even if they adhere to the rules of politeness, the condescending arrogance in their eyes cannot be hidden.
After the meeting, Director Li took a meeting memo to the office of the Presbyterian Hospital and reported the meeting to the old man sitting behind the desk.
After listening quietly to his report, the old man's index finger nodded on the table and said.
"Let me draw a line for you, and you can just follow the talk."
Director Li said respectfully.
"Please speak."
"Economic cooperation is welcome, and political compromise is avoided."
Director Li looked nodded and said.
"I understand."
Although it is only a short sentence, the amount of information is not ordinary.
Economic cooperation is welcome, which means that the lease of lunar mass accelerator can be discussed. On the premise of meeting its own transportation needs, it can sell part of its excess capacity to international customers.
There is also the construction of public facilities in Guanghan City, the supply of living materials and consumer goods for residents of Guanghan City, and these markets have no plans to swallow all of them on their own. If they can provide better service at a lower price, no one will refuse.
As for political compromise, it's better understood.
In a simple sentence, do business honestly and earn money together. Don't make irresponsible remarks about the Guanghan Special Economic Zone. Everyone can still be friends.
Old man: "Any other things?"
Director Li: "There is one more."
"Say it."
"The Carson hopes to be able to bring some lunar soil from us ... or a meteorite from the moon back as a symbol of our friendship."
After hearing this sentence, the old man smiled, and after thinking for a while, he said,
"AIA reported it as peach, and I should respect it as Lee."
"They gave us 1g lunar rock specimens before, and we have no reason to refuse such a request. You go to the Lunar Orbital Construction Committee and say hello, and ask them to pack a kilogram of moon soil and wait for that Carson to leave Just let him take it back. "
"Also, remember to take him back for a word."
"The resources of the Moon belong to all mankind, not the United States. No country has the right to possess it alone, but has the right to develop and use it. We welcome any country and organization to join this exploration of the future of all humanity."
"As long as everything is in the framework of peace."
"As long as they understand the principle of seeking common ground while shelving differences."
...
Jinling.
Villa of Zhongshan International.
Sitting on the ground in the study, Lu Zhou was playing with the new toy just obtained from the previous system task.
It was a black bracelet with a shape similar to that of most sports watches, and even the design of the LED screen inlaid on the surface was exactly the same.
But intuition told Lu Zhou that the materials and technology applied to that screen are probably not on the earth. In addition, there are five grooves on the side of this bracelet.
When his index finger touched the screen lightly, five black metal with a diameter of less than 10mm would pop out from the five grooves. These move slowly under the traction of a changing magnetic field, which looks very magical.
Lu Zhou tried to turn his hands over, or waved his arms. The five black metal seemed to recognize the bracelet on his hand, and followed his arm closely.
"interesting……"
Lu Zhou tried to hold one of the with his left hand, pulled it away from the magnetic field above the ring, and then released his hand. I saw the little ball as if it was tethered by an invisible spring, and the moment he let go, he bounced back like a slingshot.
"A toy of alien civilization?"
Looking at the black metal sphere above the suspended palm, Lu Zhou's look of interest became more and more obvious.
The system's description of it is very vague, without even giving a specific name, but according to his exploration, he has discovered some functions of this bracelet.
For example, the most basic, like other sports bracelets, it can measure heart rate and record time.
In addition, it also has a main function, which is to form a constantly changing electromagnetic field around the bracelet, which can control the movement of the metal ball.
At the same time, it seems that a special brain wave recognition device is built into this bracelet, which can recognize the received neural signals, convert them into electrical signals, process them through the built-in chip, and feed them back to the magnetic field control unit in the bracelet. Use this to manipulate the movement of the five black metal in the air.
In terms of effect, this phenomenon is very strange, as if it were magic. As for what it was used for, Lu Zhou wondered a little.
In fact, this is understandable.
It's like an alien without long feet. If you get a pair of a cones from Earth, I'm afraid I can't figure out what it is 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 technological level on the earth.
But at this moment, when he felt the land boat of the bracelet, he suddenly found a familiar sign on the inside.
This sign he vaguely remembered, he had seen in a dream ...
"Xiao Ai."
The drone floating on the side, hovering over the small TV, flew over.
【What's matter? the host. (???? ▽ ??)]
Staring at the five metal floating in his hand, Lu Zhou thought for a moment and asked, "Do you have any information about this thing in your database?"
When this order was issued, Lu Zhou's heart didn't really hold any hope.
After all, he has asked similar questions countless times, but he didn't get any valuable answers.
The only thing he can conclude now is that Xiao Ai is probably the intelligent navigation program on the spacecraft that Galan civilization finally sent to the center of the galaxy.
It's a pity, however, that the memory of the last universe is as if it were completely deleted from its database, and no valuable clues have been left-
[Xiao Ai's database seems to have information on this thing. (????????????) ????]
Lu Zhou: "... ????"
For the first moment, Lu Zhou thought he was wrong.
It wasn't until he reconfirmed this line of text on the small TV that he suddenly returned to God and immediately asked.
"Get out the information about it, all!"
【I'll try and find it……(????????????)????】
Very rare, this time Ai disappeared a little longer.
Just when Lu Zhou doubted whether it crashed or ran for a game, the light blue text finally emerged from the small TV.
[Strange ... traces are clearly left in the cache, but it seems to be deleted ... Σ (° △ °

) ︴]
[All in all, this seems to be a weapon, it used to belong to an officer who seemed very powerful. (＠ _ ＠;)]
Lu Zhou: "...?"
What the is that anyway? !!
But what surprised him more was another matter.
If it wasn't for Xiao Ai's expression, then she probably found it. In her "memory", there seems to be a trace of something deleted.
But then again, is there such a thing as "memory" in artificial intelligence? And can this memory thing exist independently of the hardware?
Just when Lu Zhou was thinking about this problem, another line of text appeared on the small TV.
[Otherwise, master, give it a try, use your imagination or something ... fire it in a certain direction? (° ー ° 〃)】
Imagination?
arms?
Launch out?
Staring at the five metal floating on the palm of his hand, Lu Zhou was lost in thought.
Suddenly, his heart moved, as if thinking of something, and he quickly looked at the vase near the wall.
"If it's a weapon ..."
Attention gradually focused on the flowerpot. Although I knew that I might look like a Form 2 student, it didn't matter that Lu Zhou thought that there were no other people in the study.
The heart rate index on his wrist began to change. I don't know if it was the illusion of Lu Zhou. He felt that the five metal floating above his palm began to tremble gently.
For a moment, as if a trigger was pulled.
The huge back force climbed up to the wrist and forearm. Lu Zhou hadn't recovered what was going on. The vase he was staring at was cracked open.
Like ...
It ’s the same as being hit by a bullet,
At the same time, one small metal ball floating on the palm was missing.
Looking at the deep bullet hole left on the wall, Lu Zhou's eyes finally appeared once again.
"Magnetic slingshot?"
Or something like that.
After all, he didn't know how to call this thing. The only thing he could determine was that there was probably some special controlled electromagnet inside the metal ball. When he "issued the attack command", it was stored The electrical energy in the energy container is released and converted into a magnetic field that repels the bracelet in an instant.
The whole ball was like a projectile placed on a slingshot, and was ejected in an instant.
Although it is only a simple thing in principle, it sounds quite incredible.
In the end, what kind of electromagnet can make a 10mm large metal ball launch like a bullet? Not to mention, it is extremely difficult to integrate the electromagnet and the control chip into a small ball with a diameter of less than 10mm.
At least the recoil coming from the wrist can feel that the magnetic field that drives this thing is not small.
The glass shards staring at the corner were lost in thought, and Lu Zhou said after thinking for a while.
"... clean this up."
Xiao Ai: [Okay, master ~]
Have a chance to study the structure inside.
For this [sample] that exceeds the level of the earth's science and technology too much, Lu Zhou does not expect to be able to restore all the technology from the inside through reverse engineering, and reproduce an identical copycat in the real world.
However, referring to some of these designs, maybe it can still have a lot of inspiration for science on earth.
For example, more advanced magnetic field control technology.
For example, magnetic levitation technology and so on.
Controlling the drone fluttered past, while clearing the ground glass slag, Xiao Ai also helped Lu Zhou recover the metal embedded in the wall, and used the repair foam to remove the bullet marks on the wall. Clean it up.
Watching Xiao Ai control several drones and sweeping robots to clean up the scene ~ EbookFREE.me ~ Lu Zhou took off the bracelet worn on his right hand and set the five metal back in turn.
Just when he was about to set aside this matter, turned on the computer and continued to search the literature, looking for that "great enough research project", the doorway knocked suddenly.
Closing the laptop that had just been opened, Lu Zhou got up and went downstairs to the porch and opened the door.
He originally thought that it was Wang Peng who heard the noise in the room and knocked on the door to see his condition. However, it was Brother Luo who did not expect to appear at the door.
Looking at Brother Luo unexpectedly, Lu Zhou asked with a strange expression.
"... Why did you come over from Shanghai?"
"What you said, I am also a professor at Jinling University. Isn't it normal to come back?"
Looking at the "brilliant" unsmiling smile on Brother Luo's face, Lu Zhou restrained the urge to roll his eyes and asked with a sigh.
"Say, what the is going on?"
"Looks like you don't know yet." Luo Wenxuan grinned. "I just got a call to your office."
"phone?"
"Uh-huh, who do you guess?"
"who is it……"
"Royal Swedish Academy of Sciences!"
The moment he heard the name, Lu Zhou froze slightly.
Just then, he suddenly remembered what day it is.
"Don't ..."
"Hahaha! That's right! Looks like you guessed it!"
Finally, there was no need to perform any more. Luo Wenxuan laughed loudly, and was even more excited than winning the grand prize. He stretched out his arms and caught Lu Zhou's neck. Pressing Luzhou's shoulders.
"Niubing, Brother Lu!"
"congratulations!"
"You are winning again!"
