Cheng Xin subconsciously stood up, and seeing that everyone's eyes were focused on herself, she suddenly felt a little at a loss, and her pretty face turned red.

"I ...... My thoughts are...... It's ......"

"Don't be too nervous, we're just doing a preliminary discussion now, and you can just express your thoughts normally."

Pang Xuelin said.

Maybe Pang Xuelin's gaze was not as aggressive as it was at the beginning, and even had some encouragement.

Cheng Xin's emotions gradually calmed down and said, "I...... I think of it this way, the most likely resource to be exploited at the moment, I think is nuclear weapons, and in the absence of a technological breakthrough, that is the largest energy body that humanity can put into space. Imagine a spacecraft or probe with a huge radiant sail, a thin film similar to a solar sail that can be propelled by radiation; Not far behind the radiant sails, a series of nuclear explosions are produced at certain intervals......"

Without waiting for Cheng Xin to finish speaking, Vadim said: "This is impossible, if the spacecraft carries so many nuclear weapons, there is no way to push them through a nuclear explosion!" ”

"No, the nuclear bomb is not on the ship!" Cheng Xin shook his head and said, "The spacecraft is just composed of sails and probes, light as a feather, and it is easy to be accelerated by the radiation of a nuclear explosion. ”

With that, Cheng Xin took a dozen paper cups from the water dispenser behind him and placed them one by one on the table at equal distances.

"The nuclear bombs are distributed over the initial short course of the spacecraft, where they are pre-launched with traditional propulsion."

She held a pen and moved along the row of cups: "The moment the ship passes each nuclear bomb, the nuclear bomb explodes behind the sail, creating propulsion. ”

Pang Xuelin and Vader glanced at each other.

"Beautiful!"

Vader clapped softly.

Pang Xuelin just smiled, not surprised.

If not involved in politics, this girl does have excellent talent.

Cheng Xin secretly glanced at Pang Xuelin, and saw that Pang Xuelin did not react very much, and was slightly disappointed in his heart.

She continued: "We can call it route propulsion, this route is called the propulsion segment, it is only a very small part of the entire route, estimated by a thousand propulsion nuclear bombs, can be distributed over five astronomical units from the Earth to Jupiter, or even less, compressing the propulsion segment to the orbit of Mars, with current technology, this can be done." ”

Pang Xuelin turned his gaze to Vader.

Vader exclaimed, "It's a good idea, and more importantly, it's a very low-cost solution!" ”

Pang Xuelin nodded: "That's true!" ”

The first step in this program is to put a large number of nuclear bombs into Earth orbit, and the delivery vehicles are readily available, using existing ballistic missiles.

The "Minuteman" and "Trident" series of the United States, the "Topol" and "Bulava" series of Russia, and the "Dongfeng" and "Julang" series of China can all directly send nuclear bombs into low-earth orbit.

Even medium-range ballistic missiles plus booster rockets can do this.

After the emergence of the three-body crisis, countries have successively taken advantage of agreements on large-scale reductions in nuclear weapons.

This method is much less costly than dismantling and destroying missiles and nuclear warheads on the ground.

Pang Xuelin said with a smile: "In this plan, every explosion of the nuclear bomb increases the speed of the spacecraft by one level, much like climbing a ladder, Ms. Cheng Xin, what do you think of the ladder plan?" ”

"Huh?"

Cheng Xin was slightly stunned, as if he didn't understand why Pang Xuelin wanted to ask for his opinion.

Pang Xuelin said with a smile: "You proposed this plan, of course you have the right to name it." ”

Cheng Xin said: "The ladder plan is very vivid, so let's call it the ladder plan." ”

Pang Xuelin nodded and said, "The next step is the problem of the detector itself." ”

Vader said: "Professor Pang, there are no people from the PIA Technology Planning Center yet, but among the next people, there are several top space vehicle design experts, including the Cassini probe designer. Look, how about we talk about the detector when we're all here? ”

Pang Xuelin said: "Yes." ”

At this time, Vadim suddenly said in a loud voice: "Professor Pang, I think there is another very important issue that we need to consider. ”

"What's the problem?"

Pang Xuelin was slightly stunned.

Vadim said: "The detection effect of the detector! You know, even if the probe is not captured by the enemy ship in the end, but the probe does not have the ability to slow down, even considering the deceleration of the trimaran fleet, the two sides will pass by at a relative speed of at least five percent of the speed of light. As a result, the probing window becomes narrow. Due to the quality limitations of the detector, it is not possible to carry out active detection such as radar, only passive detection of information reception. The main information that can be received is electromagnetic waves, and the enemy's communications must have long ago not used electromagnetic waves, but used mediums such as neutrinos or gravitational waves, which are beyond the reach of human technology. There is another important reason: due to the presence of Tomoko, the probe program is completely transparent to the enemy from beginning to end, making the chances of success even slimmer. In short, there is little to be gained compared to the huge investment in the plan, and more to symbolism......"

Vadim didn't go on, but everyone understood what he meant.

Although under the Wall-Facing Act, the Planetary Defense Council is unlikely to veto the exploration plan led by Pang Xuelin.

But the resources required and the implications of this plan are questionable.

For a while, not only Vadim, but also Vader and Cheng Xin turned their attention to Pang Xuelin.

Pang Xuelin smiled and said, "Who said that I want to install a detection instrument on the detector." ”

Vadim and Cheng Xin were stunned.

Pang Xuelin continued: "I'm going to send someone over, if the detector is too small to fit a person, then - only the brain!" ”

Vadim froze for a moment, then subconsciously turned his gaze to Vader.

This kind of thing seems to have been said only by Vader in the past.

At this moment, he felt that Pang Xuelin and Vader were simply like gods.

Vader was bright-eyed, and in an instant he even had the idea of having a long talk with Pang Xuelin all night, and the person facing the wall in front of him really had an idea that suited his appetite too much.

Cheng Xin looked at Pang Xuelin incredulously, his mouth slightly open.

Send only the brain!!

These words shook her brain, making her involuntarily stir, and the whole person seemed to be electrocuted.

She subconsciously moved a few steps back, trying to get away from Pang Xuelin.

Pang Xuelin ignored everyone's reactions, in the original book, the ladder plan finally chose to send a brain to the three-body world because of the insufficient carrying capacity of the detector.

The owner of this brain is the hidden male protagonist, the abyss-level licking dog Yun Tianming.

Yun Tianming is Cheng Xin's classmate, a dick man with terminal cancer.

At the end of his life, he got a windfall, which coincided with Ms. Say's proposal for the Stars Project, so Yun Tianming funded the purchase of a star and gave it to Cheng Xin, who had been secretly in love for a long time.

However, when Cheng Xin, who didn't know it, learned that he had a classmate with terminal cancer and an aerospace background, and happened to be eligible for the Ladder Project, he ran to Yun Tianming and asked him to agree to participate in the Ladder Project.

The heartbroken Yun Tianming finally agreed to Cheng Xin's request, and his brain was removed and put into a detector and sent to the enemy's heart.

Hundreds of years later, in the broadcasting era, Yun Tianming, who was resurrected through cloning technology, has a lofty position within the three-body civilization.

At that time, because of gravitational broadcasting, the coordinates of the earth and the three-body civilization in the universe had been exposed, and the three-body civilization was even hit by the dark forest, and less than one thousandth of the population fled the Centauri α.

In order to allow human civilization to continue, Yun Tianming sent back information to the earth to avoid the attack of the dark forest through the fairy tales that had been compiled for a long time, and took the opportunity to meet Cheng Xin.

……

But this time, Pang Xuelin was going to send a brain to the Three-Body Civilization, not for intelligence.

As a time-traveler with a God's perspective, Pang Xuelin knows most of the plots that happen in the "Three-Body Problem" trilogy.

The reason why he decided to send a probe to the three-body world was more for the future.

With his control, the worst situation between human civilization and the three-body civilization is just to fall into a state of long-term confrontation.

But that wasn't what he wanted.

In the final analysis, the three-body civilization, like human civilization, is just an ant that can be crushed to death at any time in a universe where all kinds of physical and mathematical laws are rampant and all kinds of physical and mathematical laws have been weaponized.

A cleaner of the lowest rank in the Singer civilization can easily incorporate the solar system into a two-dimensional giant painting.

A small particle of light can instantly destroy the α Centauri, making the Three-Body World a purgatory of fire.

Human civilization and three-body civilization, the two close neighbors, really need to huddle together for warmth, instead of loving and killing each other.

Therefore, Pang Xuelin needs a person, a person who can go deep into the three-body world and observe the three-body civilization at close range, so that it can become a link between the two civilizations.

Yun Tianming in "Death Eternal" is undoubtedly a qualified candidate.

……

"Okay, Mr. Vadim, you and Ms. Cheng Xin should go and get busy first, I have something I want to talk to Director Vader."

Once the general plan of the ladder plan has been determined, the remaining technical details will naturally be discussed when all the technical personnel are available.

Pang Xuelin directly drove Vadim and Cheng Xin away, and when there were only two people left in the office, he and Vader were left, Pang Xuelin said: "Let Vadim go!" ”

Vader was shocked, subconsciously opened the drawer, and before he took out the pistol, he realized that he had behaved inappropriately, looked up at Pang Xuelin and said, "Professor Pang, I don't understand what you mean?" ”

Pang Xuelin smiled: "When I said just now that I would only send brains, you subconsciously glanced at Vadim, and you think Vadim is a qualified candidate." With a background in aerospace and a long time in the intelligence service, these are all advantages of Vadim. But Vadim is your colleague, he has a family of his own, and I don't want PIA to have a director with no bottom line. Director Vader, sometimes it's good to be able to keep an eye on a goal, but it's easy to fold, and I hope that your unscrupulous means will be used against the enemy, not our own! Also, the world is so big, it's not difficult to find the right person, right? ”

Vader stared at Pang Xuelin with a pair of eyes, if it weren't for the identity of the other party, he would have taken out a gun to kill Pang Xuelin now.

This person is like a god and demon, and he feels that his whole person is seen through by the other party.

It took a long time for Vader to pull his hand out of the drawer, and he was holding a cigar in his hand.

Click.

The cigar was lit again, and Vader took a deep breath and said, "Professor Pang, if you are fine, please go back, and when the people from the Technology Planning Center arrive, I will invite you to the technical seminar." ”

Pang Xuelin smiled slightly and said, "Director Weide, you don't have to be so wary of me, I am very optimistic about you, and I hope we will cooperate happily in the future." ”

As he spoke, Pang Xuelin turned around, and just walked to the door of the office, Pang Xuelin stopped, turned around and said, "Director Weide, I want to borrow a personal ...... from you."

"Is that the girl?" Vader paused and said, "You're the wall-facer, and you have permission to take anyone!" ”

"Thanks!"

Pang Xuelin turned around and went out.

Kante, who had been waiting outside the door, immediately greeted him.

"Professor Pang, where are we going next?"

"Let's go back to the hotel!"

Surrounded by Kante and the guards, everyone went downstairs in a big way, and as soon as they reached the staircase on the first floor, Pang Xuelin saw Cheng Xinzheng walking out of an office with some difficulty holding a cardboard box.

"Professor Pang!"

Cheng Xin saw Pang Xuelin and subconsciously hid to the side.

I don't know why, for this wall-facing person, she felt a little scared from the bottom of her heart.

"Ms. Cheng Xin, can I invite you to dinner?"

Pang Xuelin looked at Cheng Xindao with a smile.

"Ah......" Cheng Xin's eyes widened, and it took a while before he came back to his senses, and hurriedly said, "Professor Pang, still don't ...... Don't use it?! ”

"Where are you going to send this cardboard box?"

"Tile ...... Director Vadim asked me to move the box to his office on the second floor. ”

I don't know why, Cheng Xin always felt that Pang Xuelin looked at her, as if he was a fierce beast that chose people to devour, which frightened her.

Pang Xuelin glanced at the guard beside him, and someone immediately went up to take the cardboard box from Cheng Xin's hand and helped her complete this task.

Pang Xuelin slowly walked in front of Cheng Xin and said again: "Ms. Cheng Xin, I hope to have dinner with you, don't refuse, this is part of the plan!" ”

Cheng Xin's eyes were dull, his small mouth opened slightly, and he looked at Pang Xuelin in shock, as if to say: "You are a wall-facing person, how can you be like this?" ”

But she looked around, and everyone, including Kante, turned a blind eye to Pang Xuelin's abuse of the power of the Wall-Facer.

Even Cheng Xin suspects that as long as Pang Xuelin shows a little interest in his body, these people may not be able to wait to send her to Pang Xuelin's bed in various ways.

It wasn't until he followed Pang Xuelin into the car and looked at the mighty guard convoy in front and behind that Cheng Xin really felt the authority of the person facing the wall.

However, what made Cheng Xin feel a little relieved was that after getting in the car, Pang Xuelin did not do anything to her.

Even when she arrived at the hotel, Pang Xuelin went directly back to the presidential suite to rest, while she herself was taken by Kanter to an executive suite specially opened for her to rest.

It's only past three o'clock in the afternoon, and it's still some time before dinner.

Cheng Xin sat on the sofa in the reception area of the room a little dazedly.

When she came out of the aerospace research group and went to PIA, she was still full of enthusiasm and felt that what she had learned was finally put to use.

But now, she regrets it a little.

She didn't know what the wall-facer was trying to do.

Before today, she had never met Pang Xuelin at all, and even before the Wall-Facing Conference, she hadn't even heard of this person.

But now, this wall-facing person has shown an inexplicable hostility towards her.

There's even a hint of the beast teasing its prey.

Cheng Xin couldn't figure out where he had offended the other party.

This kind of doubt, until dinner in the evening, she asked: "Professor Pang, ...... me Haven't I ever offended you? ”

Pang Xuelin said while cutting the steak: "Offend me? Nope! ”

"What about you...... Then why are you ......?"

Cheng Xin didn't know what to say, the other party invited him to dinner, he couldn't say that the other party wanted to hurt himself!

Pang Xuelin smiled and said: "Oh, you said that I invited you to dinner, don't you allow me to be a fair lady, the gentleman is good?" A beautiful girl like you, there should be a lot of boys who usually pursue you, right? ”

Cheng Xin looked at Pang Xuelin without blinking, of course she wouldn't think that Pang Xuelin had taken a fancy to her, just the thick ridicule in the other party's tone made her feel very uncomfortable.

Pang Xuelin swallowed the beef in his mouth, picked up the napkin, wiped his mouth slowly, and said with a smile: "Okay, I won't tease you." You did well in the afternoon, I happened to be short of a personal assistant, and I fancy your talent, so I hope you can come and work with me! ”

Cheng Xin's heart tightened and said, "I...... What if you don't! ”

Pang Xuelin smiled faintly: "This is part of the plan!" ”

Cheng Xin looked at Pang Xuelin blankly, his eyes gradually turned red, and a layer of mist appeared in his eyes, and after a while, Douda's tears kept dripping: "Professor Pang, you ...... How can you do that...... Whining...... You abuse the power of the wall-facer! ”

The smile on Pang Xuelin's face gradually dissipated, looked at Cheng Xin lightly, and said, "Are you questioning the person facing the wall?" ”

Cheng Xin was shocked, and quickly shook his head and said, "No...... No! ”

Pang Xuelin took out two tissues, handed them to Cheng Xindao, and said, "Wipe away your tears and talk to me well!" ”

"Oh!"

Cheng Xin covered his cheeks with a tissue, and after a long while, he raised his head and looked at Pang Xuelin with red eyes.

Pang Xuelin said lightly: "The ladder plan was proposed by you, so you continue to keep an eye on this project on PIA's side until the project is completed, and then return to me as an assistant." I'll ask Kanter to transfer your file to the Wall-Facing Office tomorrow, understand? ”

"Got it!"

Cheng Xin said a little aggrieved.

"Okay, hurry up and eat, this is the top blonde Ataki steak, flown in from France, during the transportation process, the meat is brought to minus 43 degrees, supplemented by a cold wind blowing at a speed of 120 kilometers per hour, which can keep the meat fresh forever. This steak costs more than $20,000, so don't waste it! ”

"Huh?!"

Cheng Xin's eyes widened, even if she worked for PIA, the price of 20,000 US dollars was enough to cover her salary for half a year.

For dinner, Pang Xuelin sent Cheng Xin away directly.

This made Cheng Xin suffer a little from gains and losses, and she was even ready to feed the tiger with her body, but Pang Xuelin didn't seem to be interested in her body.

Looking at Cheng Xin's distant back, a faint smile appeared on Pang Xuelin's face.

This girl is very nice, beautiful and kind, but the Virgin is too sick and under-trained.

The reason why he transferred her to his side was that on the one hand, he stared at her and saved her from bad things in the future, and on the other hand, Pang Xuelin was not prepared to let her have too many entanglements with Yun Tianming.

Not to mention anything else, the star numbered DX3906 given to her by Yun Tianming alone is the source of the bad thing.

In the era of deterrence, because of the discovery of two planets on DX3906, as the owner of DX3906, Cheng Xin was awakened by the federal government.

By selling the ownership of these two planets, Cheng Xin gained a huge fortune, and at the same time, he officially entered the political arena and ran for the sword bearer.

All this became the source of bad things later.

Therefore, Pang Xuelin was not ready to let Cheng Xin receive this gift at all, and even did not give Yun Tianming the opportunity to buy stars at all.

However, for Yun Tianming to be the candidate for the ladder plan, Cheng Xin is also needed to come forward to contact, which is why Pang Xuelin continues to let Cheng Xin stay in PIA.

Back in the room, Pang Xuelin logged in to the computer, entered the interface of the United Nations just announced by Ms. Say, thought about it, he took out his mobile phone and dialed Say: "Ms. Say, I want to buy a star...... Haha, it's considered a support for the Stellar Project...... That's right, the number of that star is DX3906, let's send someone over in the evening and sign the agreement as soon as possible...... As for the owner of this star, I would like to give it to a girl, her name is Zhuang Yan! ”
