"Students, the first two years of vocational high school have also ended." The bespectacled homeroom teacher tapped a stack of paper in his hand on the podium, "In the next year, you will enter different companies, institutions, or departments for internships. So I want you to fill in what you want to do. We will assign you a place to go based on your ideas and needs. ”

As soon as these words came out, there was an uproar in the class. Teenagers and girls kept talking and talking, whispering, or laughing.

"Say yes." Xia Xiaoyan quickly wrote a few words on the paper, "You see, the dream is to build a nuclear fusion spaceship, and what I hope to enter is some construction factory. ”

"Hmm...... Then I'm nuclear fusion. Shen Zixuan wrote Juanxiu's font on the paper. But at this moment, she felt something surging in her head, prompting her to want to write. I subconsciously wrote a dozen words on the paper.

"Okay, classmates, give the paper to the group leader when you write it." The head teacher noticed the change in Shen Zixuan's face and clapped her hands heavily, distracting her attention.

"Are you alright?" Xia Xiaoyan looked at Shen Zixuan's face worriedly, "Just got distracted?" ”

"Well, it's okay, it's just a little bit of thought." Shen Zixuan looked at his paper and found that these words were written on it.

"Plasma Physics, Theoretical Physics, Nuclear Science and Engineering?" Shen Zixuan read these words fluently, and always felt that these words had existed in his memory for a very long time and time.

"Oops, it looks like you secretly made up the lessons." Xia Xiaoyan smiled, "Is it written, I'll hand it over to the team leader after it's written?" ”

"Ah...... Ah, okay. Before Shen Zixuan had time to think, the paper in his hand was subconsciously handed over, passed through Xia Xiaoyan's hand to the hand of the team leader, and finally came to the head teacher.

I don't know why, she always feels that the paper collected this time is much cleaner than what she remembers.

"Well, the students are very ambitious." The head teacher swept the papers, "Although we are in a computer mechanics class, many of the male students want to join the army, and there are many who want to make the ordinary robots on the street more intelligent." ”

"The girls are also very good, I see that there are people who want to build spaceships, and I see ...... Shen Zixuan. The head teacher clicked Shen Zixuan's name and made her stand up subconsciously.

"You don't have to stand up." The head teacher smiled at her and pulled out the piece of paper, "Shen Zixuan's ideals are very ambitious, and he wants to build a nuclear fusion device. Something like this is really important to our planet. The picnic area exists for a day, and everyone has to live in a black tower, in a membrane. ”

"At the same time, most of the energy has to be used to maintain the black towers and membranes, otherwise many elderly people will get sick and die, and many children may be born sick." The head teacher looked at Shen Zixuan, "But if the nuclear fusion that Shen Zixuan wants to study succeeds, maybe this situation will be better." ”

"It's a great idea." The head teacher said, clapping his hands gently.

Subtle applause rang out from all over the classroom.

Then, it converged into a river and flowed in Shen Zixuan's ears, making her a little overwhelmed.

"Ah, I just had this idea, I haven't done it yet." Shen Zixuan waved his hand in a panic.

"It's okay." The head teacher nodded slightly, and a trace of sadness flashed in the eyes of the students, "If you want to do it Shen Zixuan, in fact, I don't recommend you to go directly to the internship." ”

"Huh?" Shen Zixuan grew his mouth.

"You fill this out, I suggest you go to college." The head teacher said, "And your grades are also good, I'll help you write an application, first go to the university to learn some languages from other countries, and then consolidate the foundation of mathematics." It will take about a year, and then you will be able to enroll. ”

"Really!" Shen Zixuan's face was overjoyed.

"Yes, so do you, the rest of you." The head teacher swept to the others, "Your ideals are all valuable and meaningful. ”

"So go, students, the future belongs to you, and the future will rise in your hands and become even better!"

……

"So, I'm really going to college." Shen Zixuan looked at the stamped application form in his hand, "You won." ”

"I'll just say it." Xia Xiaoyan smiled naturally, "You must be able to." ”

"But are you going to do an internship?"

"Not necessarily." Xia Xiaoyan took out a piece of paper from her pocket, "What do you think this is?" ”

"University ...... Application? ”

"Yes, the teacher also said that my ideal is good, and I just need such manpower." Xia Xiaoyan said, "However, our vocational high school education and knowledge are still too little, so we have to continue to study." ”

"The university you applied to is ......"

"Just like you, Xiao Xuan." Xia Xiaoyan said, stretching out her hand, "We will be classmates in the future, and maybe colleagues in the future." ”

"Let's do it together!"

"Well, let's do it together!"

……

"Researcher Shen, your theoretical formula is correct and has been verified." After hearing this, Shen Zixuan, who was restless in the office, finally breathed a sigh of relief, "Combined with the materials we unearthed in the picnic area, it can help us extend the running time from 1,000 seconds to 5,000 seconds!" ”

"It's good to succeed." Shen Zixuan slumped into his chair and looked at the reflection of the opaque glass window. Since I entered university, then graduate school, graduated with a doctorate, and now I am involved in work, I am in my thirties.

"But I didn't expect it to succeed in twelve years." As soon as he thought of this, Shen Zixuan would think of the night twelve years ago, what Xia Xiaoyan and himself agreed together, "It's a pity that I work confidentially now, and I can't contact her." ”

"But she must know that in a few years it should be hybrid power generation technology, and then she will be able to build airplanes, spaceships, and fly farther." After Shen Zixuan thought of this, the pressure in his heart was also much more relaxed.

"Researcher Shen, the above suggests that you take a good rest." The colleague who came in to notify also had a bright smile on his face, "It is estimated that the future evaluation and bonus are indispensable." ”

"This stuff is quite important." Hearing this, Shen Zixuan's mood also made a lot of joy, "Also, a good rest can lead to better research results." It's more materials that bind us now. But now that the picnic area has opened up a lot, we can expand the city with enough energy. ”

"yes, it's all thanks to you."

"I just made my own contributions, and I'm not good at materials science and engineering." Shen Zixuan waved his hand slightly, looking at the office where he had worked for several years, a feeling of relief rose in his heart, "Next, let's continue to work hard." ”

……

"I didn't expect to be able to see the success of nuclear fusion." In the basement of the research institute, Xia Xiaoyan, who was already full of white hair, looked at Shen Zixuan with a smile on the corner of her mouth, "It's a pity that we are already in our fifties, and we can't go to the spacecraft to experiment in person." ”

"Aren't there still a lot of young people?" Shen Zixuan's fingers tapped lightly on the tabletop, and several gaps appeared in the sleek wall, from which a simple drink device appeared, and after pouring two cups of tea, it was delivered to the two of them by a tray.

"The future of humanity is still a long one." Shen Zixuan sipped the drink in the cup, and when the TV screen went black, he saw his own blurry reflection, "Thanks to you, Academician Xia, there is a spaceship with one-third of the speed of light." Enough for us to sail. ”

"It's just that it took some time to fix the remaining protective devices of the aliens." Xia Xiaoyan rubbed her fingers, and in the three-dimensional projection, a earth full of torrential rain appeared, "But thanks to the Xuanwu unearthed by Bing Shijue, everyone is safe and sound inside, but there are no living creatures on the surface of the earth." ”

"The first layer of basalt should have stored a lot of seeds from the earth, as well as biomes." When Shen Zixuan spoke, there was a rapidly sliding table on the side of the projection in front of him, "Although the biological system is not complete, there are not too many threats in the interior of the earth. ”

"It's just that the external threat hasn't been solved yet, but if the black cavity is there, it can buy us hundreds of years." Xia Xiaoyan's fingers flicked the handle of the cup, "But with the recent synthesis of telomerase, our lifespan can be extended a lot." ”

"The theory is that you can live to be 300 years old, right?" Shen Zixuan smiled, "Now that we are fifty or sixty years old, we are actually equivalent to people in our twenties. ”

"Maybe after the aging state of the brain can be repaired, you can live a little longer." Xia Xiaoyan picked up the water cup and blew on the hot air, "There is also the exotic land invented by Bai Qiuyue, which can broaden people's lifespan at the virtual level. ”

"It's just a little bit less realistic." Shen Zixuan nodded, "But several times the time is too useful for humans." ”

"Don't talk about that, do you have any plans for the future, nuclear fusion is almost developed now." Xia Xiaoyan asked, "Is there anything else you want to do?" ”

"Yes, the power of nuclear fusion has basically been mined, and one-third of the speed of light is the limit." Shen Zixuan held the water cup in both hands, "We humans were very happy when we first got the alien technology, advancing from the ordinary propulsion speed to the speed of light. But it was later discovered that one-third of the speed of light is the end of nuclear fusion. ”

"Of course, for civilians, there must be a lot of room for excavation. But if you want to leave the black chamber, leave this alien protective device...... Or rather, a trap-like device, and something else has to be found. ”

"Why?" In Xia Xiaoyan's old face, her eyes flashed with a strange brilliance.

"Academician Xia...... Xiaoyan, you're a spaceship expert, and you're still asking me this? After Shen Zixuan heard this, he put down the water glass and smiled very pleasantly.

But after laughing, there was a deep worry on his face.

"We use a spaceship that can only hold a few dozen people, and it can indeed reach a third of the speed of light. But this is based on the fact that almost half of the spacecraft are engines. Shen Zixuan sighed, "The bigger the spaceship, the slower the speed, although there is a Hall engine now, it can still make up for the speed to a certain extent." ”

"But this is in the solar system, even if it reaches the same speed of light as the Ice Beginning, it will take three years to fly to the body, and I don't think a level 3 civilization will use such a slow way like us."

"Didn't Bing Shijue say that the speed at which they crossed the galaxy was even a few decades, reaching hundreds of times the speed of light!"

"You've got other plans, right?" Xia Xiaoyan's eyes moved slightly.

"Yes, I'm going to work on an antimatter engine, and then combine it with Hall thrusters, maybe I can get the ship to the speed of light before I'm eighty." Shen Zixuan said, "And in these years, people's life spans will also be extended, and I can continue to shine." ”

"Well said, Academician Shen." Xia Xiaoyan clapped her hands, but her eyes were fixed on the air.

In the air, there was a progress bar that everyone except Shen Zixuan could see.

"Xiaoyan, what are you looking at?" Shen Zixuan noticed the deflection of Xia Xiaoyan's gaze, "Did you bring the pupil display that you were testing recently?" ”

"Looking at the state of your awakening over the years." Xia Xiaoyan stretched out her hand and slid slightly.

A minimalist page appears between the two.

It's an exotic interface button.

In an instant, Shen Zixuan felt that there were countless faint currents surging inside his brain, and decades of experience and decades of reality were fused together in an instant.

I researched the matter of nuclear fusion vertigo, the matter of Xuanwu being discovered, the establishment of the Xuanwu Alliance, the matter of Bing Shijue's fight against aliens, and the matter of the Starry Sky Sect...... All of them are beginning to coalesce into a complete memory.

“…… Have I been asleep for so many years? Shen Zixuan lowered her head, so many memories were slightly modified and still had an impact on her brain, but it was not as painful as she imagined.

Because of Xia Xiaoyan's company, those false, but also with a few real memories protect her.

"yes, almost forty years." Xia Xiaoyan stretched out her hand to Shen Zixuan, "It's time to wake up, Zixuan." ”
