The Science Fiction World of Xueba

Three years passed by in a flash.

On a spring evening, in a corner of the city.

The setting sun hangs over the undulating mountains in the west, and the sky is full of red clouds, reflecting the green land below.

In this timeline, the shrimp civilization has not launched any counterattack plan, and naturally there is no mention of the blight sweeping the world.

After decades of ups and downs in human civilization, after the counterattack that shocked the world, the peace of the past has been restored.

Pang Xuelin took Chris's hand and walked along the riverside of the city's landscape.

Big Murphy held Little Murphy's hand and ran around laughing and laughing in front of him.

Chris smiled and said, "Husband, this girl Murphy, it's true, she's going to be a bride in a month, and she's still like a child."

Pang Xuelin showed a gentle smile on his face, and said: "This is also very good, I hope she can be so happy in the future."

Chris rolled his eyes at him and said, "What about me?"

Pang Xuelin hugged Chris's waist and said, "Of course you are the same."

...

a month later.

Pang Xuelin married Murphy.

That night, after a fierce battle, Pang Xuelin looked at his wife who had fallen asleep beside him, and finally decided to return.

He has already asked the system that in this new timeline, after he returns, the time on Earth will come to a standstill.

If he wants to come back later, he can come back anytime.

He has been in the world of interstellar crossing for many years, and the journey of Gargantua, because of the effect of the theory of relativity, made him unable to figure out how long it took in the real world.

He has to go back and have a look.

In addition, Qi Xin was still detained in the hands of the United States, and he had to go back and find a way to rescue the girl.

Pang Xuelin took a deep breath, and said silently in his heart: "System, clear the task rewards, return to the real world."

next second,

The picture in front of Pang Xuelin flashed, and he reappeared in the system's lottery space.

"Congratulations to the host, successfully completed the "Interstellar" world mission, and rewarded the host with a chance to return to the world he had experienced. Currently, the host has accumulatively had two such opportunities."

"In addition, the host can randomly draw a piece of plane technology as a reward."

Pang Xuelin turned his gaze to the Russian roulette in front of him. On the roulette, there were four technologies divided.

1. Anti-gravity technology

By shielding the gravitational force, the gravitational effect of the planet on the aircraft is released, so that the aircraft can enter space with extremely low energy consumption.

A landmark technology for a civilization to enter the era of great interstellar navigation, from which technologies such as curvature engines, gravitational wave communication, gravity bombs, and artificial black holes can be derived.

2. Hibernation technology

Through the interaction of drugs and hibernation liquid, people enter a long-term deep sleep state.

In the process of deep sleep, the consumption of human nutrients is extremely low, allowing human beings to span hundreds or even thousands of years.

One of the key technologies of carbon-based civilization interstellar travel can also be used for time migration (going to the future through hibernation). Once this technology spreads on a large scale, it is likely to trigger a social and ethical crisis.

3. High-power Hall thruster technology

The electric field generated by the magnetic field accelerates the charged ions, forming a jet of plasma that propels the spacecraft forward. This approach will provide more efficient and safer propulsion systems for long-duration missions. In addition to being used for asteroid missions, the new propulsion system will also be used in missions such as establishing a base on Mars and launching large quantities of cargo into space. It is an essential technology for deep space exploration in the star system and one of the key technologies for space industrialization. It can be used in planetary exploration, space city and space factory orbit maintenance, asteroid mining and other fields.

4. Molten salt nuclear reactor technology

One of the fourth-generation nuclear reactor technologies, the basic principle is that the core uses fluoride salts of metals such as lithium, beryllium, sodium, and zirconium, and dissolved fluorides of uranium, plutonium, and thorium as fuel. Conditions form molten salt flow directly into the heat exchanger for heat exchange.

Among them, lithium fluoride, beryllium fluoride, sodium fluoride, and zirconium fluoride are carrier salts, which provide molten carriers and improve the physical and chemical properties of the eutectic; uranium fluoride and plutonium fluoride are fission fuels, which generate heat and neutrons ; Thorium fluoride and uranium fluoride are multiplication fuels, which absorb neutrons to generate new fission fuel uranium or plutonium, which re-enter the reaction cycle after on-line extraction treatment.

The fuel produced by a molten salt reactor can be re-equipped with a new reactor after several years of operation, which is extremely economical.

At the same time, due to the direct heat exchange method of fuel, it has the advantage of being miniaturized, so it has a bright prospect of providing power for ships and aircraft.

...

"Let's start the lottery."

Compared with before, Pang Xuelin has become more and more indifferent to drawing these prizes.

Of these technologies, the most attractive is undoubtedly the anti-gravity technology.

However, if the anti-gravity technology is used in the real world, there are still many difficulties in the engineering field that need to be solved if it is to be truly realized.

Among other things, the gravitational shielding layer alone requires a major upgrade of human basic industries. The reason why humans in the interstellar world can get anti-gravity technology so quickly is entirely because of the industrial foundation left by the shrimp civilization. for the sake.

The second hibernation technology, this technology is not very difficult to implement in the real world, the trouble is that it cannot be applied on a large scale in a short period of time.

Unless there is a great leap in the level of human spaceflight technology and the ability to conduct large-scale manned interstellar exploration in the periphery of the asteroid belt, this kind of round-trip requires a long journey in units of years, and hibernation technology will be useful to a certain extent.

As for the large-scale rollout of applications for some terminally ill patients in the real world, it is theoretically possible, but how to solve the ethical issues involved is even more difficult in sociology than in its technical implementation.

The third high-power Hall thruster technology, this technology is dispensable for Pang Xuelin, because he has obtained a complete technical system of electromagnetic orbital launch technology, including the related technology of Hall thrusters.

On the contrary, the last molten salt reactor has more practical significance in the real world.

In the real world, commercial controllable nuclear fusion is difficult to break through in a short period of time. Therefore, the fourth-generation reactor technology has become the focus of all countries competing for breakthroughs.

The molten salt reactor is one of the most concerned fourth-generation nuclear reactor types.

Therefore, compared to the other items, Pang Xuelin prefers the molten salt reactor technology.

Perhaps it was the thoughts in Pang Xuelin's mind that played a role. After a minute, the pointer slowly stopped on the Russian roulette.

"Congratulations to the host, you have obtained a complete set of technical and technological materials for molten salt nuclear reactors."

"Ha, I didn't expect to draw this."

Pang Xuelin smiled slightly. This interstellar world trip, a chance to return to the plane world, and a full set of technical materials for the molten salt reactor are completely enough.

The fourth-generation reactors currently being developed in various countries can be divided into two types according to the neutron energy: three types of fast neutron reactors and three types of thermal neutron reactors.

The molten salt reactor is one of the three types of thermal neutron reactors, and because of its various advantages, it has become the most popular type of reactor.

First of all, molten salt reactors have higher safety.

The liquid molten salt reactor uses high-temperature molten salt as the nuclear fuel, which doubles as a heat transfer agent, and does not require special fuel assemblies, thus eliminating the possibility of core melting accidents.

In addition, the low vapor pressure of molten salt reduces the occurrence of breach accidents. Even if a breach accident occurs, the molten salt will quickly solidify at ambient temperature, which can prevent further expansion of the accident.

Second, molten salt reactors can effectively utilize nuclear resources and prevent nuclear proliferation.

Especially for thorium-based molten salt reactors, since the thorium used in thorium-based molten salt reactors cannot be used for nuclear weapon manufacturing, the promotion of thorium-based molten salt reactors can greatly reduce the risk of nuclear proliferation.

Moreover, China's uranium reserves are not outstanding, but its thorium reserves are among the highest in the world.

In other words, once the thorium-based molten salt reactor is put into commercial operation, China basically does not have to worry about the source of nuclear fuel.

Thirdly, the thermal power density and power generation efficiency of the molten salt reactor are high.

The core structure of the molten salt reactor is relatively simple, so it can be designed as a small reactor with high power output.

At the same time, the molten salt reactor can adopt the Brayton cycle, and the power generation efficiency can reach as high as 45%-50%.

In addition, the molten salt reactor has the characteristics of no need for control rods, non-stop refueling, long life, and easy power adjustment, so it can be used on nuclear-powered submarines, surface ships and even various future aerospace vehicles.

Finally, molten salt reactors have diverse functions.

Molten salt reactors can not only generate electricity, but also generate high-temperature process heat to serve industrial manufacturing.

In addition, the molten salt reactor also has functions such as heating, coal gasification, methane reforming, and hydrogen production. It can be regarded as an all-around player, and it will be of great help to Pang Xuelin's future development in the real world.

After the reward was determined, the voice of the system sounded in Pang Xuelin's mind again.

"May I ask the host, do you want to return to the real world?"

"Go back."

Pang Xuelin said lightly.

The lottery drawing screen in front of him gradually dimmed. Pang Xuelin opened his eyes again and smelled a faint smell of disinfectant.

"I'm... in the hospital again?"

Pang Xuelin was a little helpless. This time he entered the world of interstellar travel. The time he traveled was 2043. Going to Gargantua should look like 2063. However, during the process of falling into Gargantua, the time and space near the black hole were too distorted. Strong, he simply couldn't calculate how many years passed in the outside world during Gargantua's time.

In addition, he later returned to 2038 with the help of high-dimensional humans, and then stayed in another timeline until 2041 before returning to the real world.

He has no idea how to calculate the time and reality in it.

But since he was still in the hospital, there should be no worries about the safety of the real world.

Pang Xuelin turned his head and saw a girl with long hair lying on the head of the bed, with the back of her head facing him, neither the imagined Yao Bingxia nor his life secretary Zuo Yiqiu.

Pang Xuelin was lying down, unable to see the girl's front face, and vaguely felt that this figure from the back was a bit familiar.

Pang Xuelin propped up his upper body. Maybe he had been lying down for a long time. He felt that his muscles were a little stiff, but the problem was not serious. After drinking the gene optimization potion, his physical fitness has been greatly improved. A limp and weak feeling after lying on the bed for a long time.

"Hey, wake up, wake up!"

Pang Xuelin reached out and pushed the girl.

The next second, the girl raised her head sleepily.

Pang Xuelin was stunned for a long time, but he didn't expect Qi Xin to be guarding in his ward.

Qi Xin opened her eyes, and when she saw Pang Xuelin, she was taken aback. Then, a look of extreme surprise flashed in her eyes. Just as she was about to stand up and call out, Pang Xuelin quickly stretched out his hand to hold her back: "Shh! Xiaoxin, Call me later, I'm fine."

After finishing speaking, Pang Xuelin asked again: "Xiaoxin, when did you come back and how long have I been asleep?"

Qi Xin was excited and joyful at the same time, with tears in the corners of his eyes, he said: "I have been back for almost a week, thanks to sister Wang Zhi, I was able to return to China so smoothly. Besides, you have been in a coma for 20 days..."

"Only twenty days?"

Pang Xuelin was slightly taken aback.

He originally thought that Qi Xin's return would take a year and a half, but he didn't expect it to be so short.

If the ratio of 10,000 to 1 is calculated normally, that is to say, more than two hundred years have passed by the outside world during the few hours when I fell into Gargantua.

Pang Xuelin couldn't help but sigh with emotion, nothing could compare to this.

If I was still in the interstellar world, hadn't encountered high-dimensional humans, and hadn't returned to 2038, even if I could survive from Gargantua, I'm afraid I wouldn't be able to see little Murphy.

"Student... Junior, are you okay?"

Qi Xin looked at Pang Xuelin and said.

Pang Xuelin shook his head, grabbed Qi Xin's hand and said, "I'm fine. Xiao Xin, tell me what happened outside during this time."

Qi Xin's pretty face flushed, and she tried hard with her right hand, but couldn't break free from Pang Xuelin's grasp, so she gave him a helpless look, and said, "Well, it's like this..."

...

Next, Qi Xin completely told Pang Xuelin what happened in the past twenty days.

Twenty days ago, Pang Xuelin suddenly fell into a coma, causing an uproar at home and abroad.

We must know that not long after the announcement of the Golden Dragon Battery, the United States detained Qi Xin for the Golden Dragon Battery, and turned against China, and the relationship between the two sides fell into an unprecedented state of tension.

Under such circumstances, as the chief scientist of the Golden Dragon battery project, Pang Xuelin suddenly fell into a coma, which naturally caused an uproar in the outside world.

Whether it is the domestic media or the public, they all point the finger at the United States.

Even people in many other countries believe that this is the hands and feet of the Americans.

After all, with Qi Xin's incident ahead, people from all over the world are used to the fact that Americans have no bottom line.

For a time, the United States was at a loss for words.

And the Chinese government announced in due course that before Pang Xuelin wakes up, it will terminate the export negotiations with any country on Jinlong batteries.

For a time, the international situation was unpredictable.

At the same time, just after Pang Xuelin woke up, WikiLeaks, who had been suppressed to death by the Americans, suddenly broke the news in the media, providing the media with complete evidence that the CIA executives ordered Qi Xin to be framed, and even CIA agents. Testimony and video recordings.

This incident caused an uproar in the United States. The Democratic Party even once again submitted a case of impeachment to Congress, coupled with tremendous pressure from China.

In the end, the U.S. announced that after investigation, it was found that this was a misunderstanding. The material in Qi Xin’s suitcase was not a new type of electrolyte material lost in the laboratory of Princeton University. Therefore, they agreed to release Qi Xin unconditionally.
