I asked you to write about Fishman, and you went crazy with your creations on the spot?

Between the lines, Sai told Luo Ji a truth that was almost unacceptable.

Zhuang Yan appears in Luo Ji's world.

It is both a coincidence and not a coincidence.

Her feelings for Luo Ji were genuine.

Her identity is real.

But her appearance shouldered a certain mission of the PDC.

Although Sai's words were not so straightforward.

But Luo Ji was a smart man.

Faced with this cruel reality, he almost collapsed.

At this moment, Luo Ji understood why there was a trace of sadness in Zhuang Yan's eyes when he first saw her. It was this faint and invisible sadness that touched the softest thing in his heart, making him feel that the whole world was full of sadness. The world was a kind of harm to her, which made him willing to spend his whole life to protect her.

Pull him step by step towards the abyss of love!

Luo Ji was unwilling to accept this reality.

He proposed to hibernate himself and meet Zhuang Yan and his children together at the end of the world!

He thought Sai would refuse.

Unexpectedly, Sai agreed happily.

——"Can! Since the birth of the Wall-Facing Project, there have been voices of opposition in the international community. Taylor's suicide has strengthened the strength of the opposition to the Wall-Facing Project.

If you make a request to reach the end of the world at this time, you will undoubtedly provide a compromise plan acceptable to both parties.

But, Dr. Luo Ji, are you really willing to do this?"

Not to mention for the sake of all mankind, as far as Zhuang Yan and your children are concerned, can you really bear to see them in desperate flames in the doomsday war? As a father and a husband, I don't think you would think so. Luo

Ji asked bitterly.

——"Do you really think I can change all this?"

It wasn't until this moment that Sai revealed the true purpose of his trip.

——"Last time you asked me why the PDC chose you as the Wallfacer, I didn't tell you the reason then. Today I'll tell you why. The reason is very simple. You can be the one on the wall because among all mankind, you are the only"two, three, three" person that the Trisolaran civilization wants to kill!

Including you getting into a car accident, including you being shot!

Although they hide it well!

But according to the exact information we got from our internal investigators hidden in the ETO organization.

This is ETO's careful planning.

And the most shocking thing is.

The instructions came directly from the Trisolaran world and were conveyed to Evans through Sophon!

This is also the only assassination order they have issued so far!"

Luo Ji couldn't believe it.

——"Why does the Trisolaran civilization want to kill me? The reason?"

——"No idea, no one knew, Evans probably knew, but he was dead. The requirement of the murder order not to attract any attention was clearly tacked on by him, further illustrating your importance. Luo

Ji calmed down and pondered for a long time.

——"I have been engaged in cosmic sociology research. Is this related to this?"

——"It shouldn’t matter. As far as we know, you have made no theoretical achievements in this area, and your research is very utilitarian, and you have even embezzled funds. I can even frankly think that you are not a good person. An absolute academic bastard.

But no matter how many negative events you have, they are all overwhelmed by one point now.

Trisolaris is afraid of you!

Among the four wall-facers, you are the only one who directly confronts the Trisolaran!

So Mr. Luo Ji, please be your own wall-breaker and find out why?

Just like I said when I first met you.

You need to find out for yourself!"

After saying that, Sai left.

The villa was empty.

Luo Ji was like a child who had lost everything, sitting slumped on the sofa.

It all happened so suddenly!

……

Seeing Luo Ji encounter a major change in his life.

The live broadcast room unexpectedly burst into cheers!

【Damn it! Well done Say! Zhuang Yan, do a better job!】

【I never expected that Zhuang Yan was actually an agent of the PDC?】

【Wow, this backstab is so cruel! So cruel! Really like!】

【Well done! This dog hair is finally getting down to business!】

【How sweet it is in the front, how bitter it is in the back】

【Retribution has finally come!】

……

Jury room.

Bingbing's face was also filled with pride.

Tanaka Yoshiki looked at Nolan and others aside

"Unexpectedly, Zhuang Yan was actually from the PDC. Is Shi Qiang playing tricks on Luo Ji? Nolan

:"I don't think it's necessarily what Shi Qiang meant. It's possible that the PDC gave Zhuang Yan some kind of instructions behind his back. Don't forget, after all, Zhuang Yan is just a college student with little social experience." What the PDC asked her to do must be to monitor Luo Ji's every move. Director

:"No matter what, this is a huge betrayal. After such a big blow, I believe Luo Ji will finally get back on track."

Han Rendong:"I think Lu Chen has obviously designed a thinking trap here. The reason why Trisolaris wants to hunt down Luo Ji should be fundamentally related to those two axioms of the universe." It's just that Luo Ji still hasn't figured out what the purpose of these two kilometers is.

Nolan:"Yes, the suspense of the second half is no less than that of the first part." I don’t know what kind of plot Lu Chen will devise for Luo Ji. Bingbing

:"Taylor's works are so exciting. I believe that Luo Ji, as the protagonist, will be even more exciting!""

Several guests nodded and agreed.

……

Zhang Beihai never expected that he would be able to go into space in his lifetime.

Looking at the huge body of the"High Frontier" in front of him, he couldn't help but think of the"Tang" aircraft carrier that had been dismantled.

The aerospace plane is one of the few breakthroughs in aerospace technology in the past five years.

After five years as commissar of the Space Force.

Zhang Beihai is about to go to the International Space Station to serve as a member of the Strategic Research Office..

Before leaving, Chang Weisi personally bid farewell to Zhang Beihai.

By the way, it was also revealed that future plans for reinforcements are still being considered by superiors.

It's just that the time is not yet ripe.

Zhang Beihai narrowed his eyes. They were in the shadow of the aerospace plane, but he seemed to see a dazzling light.

……

【Yo, the old chapter begins again】

【Why hesitate with such a good plan?】

【It's official, what else could be the reason?】

【Isn’t it surprising that there are still few examples of capable people not being promoted?】

【Zhang Beihai wants to approve the plan without making a few rounds? What are you thinking! In the Dragon Kingdom, when Hawking comes, everyone has to stand up and pay homage first】

【I remembered the graphene genius who went to the United States to be a principal a few days ago.……】

……

After Zhang Beihai boarded the aerospace plane, he met an unexpected person in the cabin.

——Ding Yi.

As a domestic physics master.

Zhang Beihai knows Ding Yi's name very well.

——"Dr. Ding, why are you going to the space station? I remember that you have just been appointed as the project leader of controllable nuclear fusion. It seems to be the third research branch, right?"

Ding Yi was speechless.

——"Can we not go to space to study controllable nuclear fusion? How can you agree with those people? Our ultimate research target is a spacecraft engine."

Perhaps the other party is a member of the Space Force Strategy Department.

Ding Yi couldn't help but complain to Zhang Beihai for a while.

Nowadays, sophons have locked up human science.

Humanity only has classical physics, quantum mechanics, and string theory that is still in the womb..How far it can go in terms of application is purely left to fate. (To read Baoshuang novels, go to Feilu Novel Network!)

However, in Ding Yi’s view, if the space fleet wants to achieve space navigation, it will be impossible to use existing chemical rockets.

As an outstanding naval general, Zhang Beihai has studied both theory and technology.

He fully agrees with Ding Yi’s views.

——"Yes, once controllable nuclear fusion technology is realized, research on spacecraft can begin immediately. I know that there are currently two major directions: working medium propulsion spacecraft and industrial medium radiation-driven spacecraft. Around these two research directions, two opposing factions have formed: the aerospace system advocates the research of working medium propulsion spacecraft, while the Space Force advocates the research of working medium propulsion spacecraft. Push radiation to drive the ship. But this kind of research consumes huge resources, so disagreements arise."

Ding Yi nodded.[]

——"You are right. I also support industrial dielectric radiation drive, but what we say is useless. Those who hold real power in the aerospace industry now are those who used to develop chemical rocket engines. According to them, we should just be honest. If we are actually engaged in controlled nuclear fusion on the ground, we will not have much say in the overall planning of the space fleet. Of course, we have to admit that the aerospace system also makes sense. The working medium propulsion spacecraft is actually a variant of the chemical rocket, but it only uses nuclear fusion as energy. The research prospects should be safer."

——"But there is no guarantee in the future interstellar war! As you said, the working medium propulsion spacecraft is just a big rocket. It uses more than two-thirds of the carrying capacity to carry the propelling medium, and the working medium is consumed very quickly. This kind of spacecraft can only rely on planetary bases. In the solar system Navigate within. Doing so is tantamount to repeating the tragedy of the A-5 War. The solar system is Weihaiwei!"

——"This metaphor is profound. But again, I understand the truth, but the key point is that we have no say!"

Ding Yi couldn't help but feel frustrated.

Not only at home, but also in every country, there is a situation where seniority is used in the ranking of employees.

——"I might as well tell you one more thing. In fact, controllable nuclear fusion technology has already achieved a breakthrough"

——"So fast?"

Zhang Beihai was surprised.

Ding Yi spread his hands

——"Can you postpone the announcement of the results a little longer, Dr. Ding Yi?"

——"put off? Are you kidding me? The media all over the world are watching. Why delay?"

——"But once the results are announced, the guys you mentioned still control too much power in this field. Once they choose the working medium to propel the spacecraft, I am afraid there will be endless troubles. You should know very well that although humans still have four hundred years to prepare, they do not have the opportunity to choose twice!"

——"There is no way, after all, they came up with this within five years." Ding Yi pointed to the aerospace plane under the seat,"This is their capital to exclude others."

Zhang Beihai frowned when he heard this.

At this time, the plane was about to pass through the atmosphere.

The strong weightlessness caused Ding Yi to have a serious reaction.

The conversation was suspended.

But Zhang Beihai deeply remembered the conversation.

In In his view, mankind must have a spacecraft capable of interstellar voyages!

No one can stop this plan!

If it doesn't work, he has only one way left!

……

【Damn it, what is Zhang Beihai planning to do?!】

【What kind of working fluid is propelled and the working medium is propelled? I don’t understand!】

【Haha, it turns out that seniority is used in salary ranking. You guessed it right0......】

【Confucianism has harmed the Chinese people for thousands of years!】

【The older generation always thinks that their experience is right, but their reasons are sometimes irrefutable.】

【The aerospace plane was developed in five years. Good guy, didn’t Sophon lock down technology? Why is it that technology has begun to explode! ?】

【Ding Yi really worked hard. It seems that Shi Qiang’s insect theory still inspired him a lot.】

【I want to know what Zhang Beihai did right now! Why is space navigation necessary? Isn't it to prevent the Trisolaran attack?】

【Brother, it seems you don’t know anything about the A-5 War.】

【To explain in one sentence, when facing a strong enemy, you must go all out and never give in! Working medium propulsion is more advanced and better than working fluid propulsion! But the risk is high! This is the contradiction between two generations of scientists, one seeks stability and the other seeks breakthroughs! Ding Yi and Zhang Beihai are both the latter, now you understand!】

【Correct answer upstairs!】

【The key is what is working fluid propulsion and what is working medium propulsion? I don’t understand this!】

……

Jury room.

Han Rendong took a deep breath:"This guy started to show off his concepts again."

Nolan:"Professor Han, to be honest, I am also curious about this working fluid propulsion and working medium propulsion. The working fluid propulsion is worthy of our existing rocket propulsion. System?"

Han Rendong punched the director:"Lao Zhang, you should be familiar with this, right?"

The director laughed:"You said rocket propulsion, I know it, but I don't know much about this medium propulsion thing, I haven't been exposed to it. This concept."

Han Rendong:"It's quite simple to say. Working fluid propulsion is just like what Mr. Nolan said. Our conventional rocket propulsion system is one of them. In addition, our aircraft also use chemical fuel. This They all belong to working fluid propulsion, and its essence is to use the principle of conservation of momentum. It injects material backward by burning fuel, and relies on action and reaction forces to push forward.

Here, the material injected backward is called work Substance, referred to as working fluid.

Our engines are all working fluid engines.

Industrial medium engines, also called working fluid-free engines, as the name suggests, can produce forward thrust without the help of working substances.

This concept was once considered possible.

It was first proposed by Chinese scientist Roger Shawyer in 2001. Once it was proposed, it attracted widespread attention in the scientific community.

Roger Shawyer's refrigerant-free engine, on the surface, is not complicated. It consists of two main parts.

One is a conical shell, which acts as a reflection cavity.

There is also a microwave generator.

The principle is: the microwave generator emits microwaves, and the microwaves are at the bottom of the reflection cavity, generating a thrust.

Although in the experiment It did produce a thrust of 16 millinewtons.

However, the thrust generated was too small to meet practical applications.

Therefore, the fluid-free engine was stranded for a time.

Since then, it has been considered a theoretical [aerospace dream engine].

Of course, There is nothing wrong with this concept when used in science fiction works.

Going back to the story, Lu Chen’s concept of a working medium-free engine goes a step further on the original basis.

He plans to use the radiation of controllable nuclear fusion to generate electromagnetic force and then propel.

This concept is good.

But unfortunately, controllable nuclear fusion is still just a science fiction concept.

Let alone a fusion-free 3.3 mass engine."

Several judges nodded:"I see."

Yang Zhenyu was at this time He glanced at the sneer sitting on the side.

Noticing the awkwardness in Mr. Yang's eyes, his expression froze slightly and his smile became even more awkward.

……

At this time, outside the screen, there was the Military Commission compound.

Du Min and Shen Qiuyuan had already broken into cold sweats.

The atmosphere at the scene was also unprecedentedly tense.

An Dingbang looked sideways at Shen Qiuyuan, and his tone was calm with rare majesty:"Isn't this a secret project you are working on?"

Shen Qiuyuan's face was reserved:"Yes, I am also surprised. Maybe... it's just a coincidence. , after all, the nuclear fusion refrigerant engine has appeared in some cutting-edge scientific forums before, and we are also doing research based on this proposition. As far as the proposition itself is concerned, it is not a secret."

An Dingbang nodded:"It seems like, It's just a coincidence. How is the progress?"

Shen Qiuyuan:"Currently, controllable nuclear fusion is making good progress. The engine without refrigerant is a project at the end of the second phase and has not been put on the agenda yet."

The generals in the audience clucked their tongues:"This kid! Let him write a science fiction, and he almost revealed the state secrets!"

Shen Qiuyuan laughed:"Actually, there are theories, and there is no guarantee that various countries are not secretly researching them behind the scenes.It can be said that the degree of realism in this work is higher than we imagined. The next development goal of medium-less thrusters is the curvature engine. These concepts are not surprising in science fiction novels.

However, nuclear fusion radiation has no refrigerant engine.

This is really the first time it has appeared in science fiction.

The concept is indeed fresh.

After all compared to the warp engine.

This is currently the most likely engine that humans can theoretically achieve space navigation."

An Dingbang nodded and did not delve deeper into the topic.

Everyone continued to look at the screen.

As a result, they happened to see Zhang Beihai buying meteorites and making bullets.

An Dingbang:"What does he want to do?".
