Hearing that the plan was rejected, Cheng Xin's heart was still very uncomfortable. He also wanted to make a big deal and prove his abilities, and the years ended like this.

Vader said: "Cheng Xin, you look unhappy, do you think we are going to retreat from the ladder plan?" Is there nothing we can do about it? ”

Cheng Xin looked at Vader and sighed: "What can we do if we don't return it?" Is there any other way? ”

"We can't retreat!"

Vader stood up and shouted: "In the future, whether it is a ladder plan or some other plan, you can only retreat if I order you to retreat, and before that, you can only move forward, forward, and advance by any means!" ”

Vader roared like a mad beast, scaring everyone.

"But what do we do next?" Director Hamill asked.

Vader said: "Send a person to go, a person can do more research and exploration, than a machine, and more intelligent, Europe has developed human hibernation technology, enough for people to hibernate for hundreds of years!" ”

"However, the living man, the hibernation equipment, plus the probe, have exceeded the limits of the thrusters!"

Cheng Xin said: "We can send a dying frozen person in, so that he is in space, and he does not need a life support system, but only needs to use the low temperature of the universe to control it below 200 degrees Celsius!"

We don't have this kind of human body awakening technology, but the Trisolaran people must be able to, cross the stellar civilization, and must have enough applications for life science!

Vader pondered for a moment and said: "Maybe we don't need to send a whole person, one brain is enough, and freezing one brain can save dozens of kilograms of mass!" ”

In the days that followed, they moved around looking for this brain, but what made Cheng Xin nervous was that the director of the center, Hamill, was killed.

On Hamill's desk, there is a picture of his wife and daughter, who have been exposed to radioactive material.

During a drive, Hamill suddenly fell into the river and died, although he was rescued, but he was already brain dead due to long-term suffocation, and Vader was just a pity.

The man was killed by Vader.

Cheng Xin was very nervous, she didn't know if the next Vader target was her own brain, and this danger made Cheng Xin more engaged in finding a replacement experimenter.

After a reunion with classmates, Cheng Xin got the news of Yun Tianming, who was Cheng Xin's classmate and didn't know him very well. But there are no stupid people who go to university to study rocket engineering.

Knowledgeable, intelligent, proficient in physics, and now terminally ill, he is very much in line with the requirements of the Ladder Project, which is the pinnacle of humanity and cannot be picked and choosed.

It's just that it's not easy to choose this target person, and it's very difficult to kill a living person, it's against the law, and who wants to take off their brains and send them into the vast space?

In order to let people die voluntarily, they urgently passed the euthanasia bill, collected several intellectuals who wanted to be euthanized, and then explained and communicated one by one.

Soon after, Cheng Xin got the backup candidate Yun Tianming, and also received a certificate, which said that she got a star, becoming the first woman in human history to get a star!

At this time, Cheng Xin felt satisfaction and happiness for the first time in her life, although she was ruthless, she also had human weaknesses, vanity, she couldn't compare, she told everyone the news, but Vader smiled inexplicably. Night Night Chinese

Taking advantage of this momentum, Cheng Xin was more engaged in work, and when he rushed to the ward, Cheng Xin told Yun Tianming about the ladder plan, with encouragement in his enthusiastic eyes.

Yun Tianming couldn't breathe with laughter. He felt ridiculous for his own self-inflicted affection, this man he had thought of in his heart, this man whom he had sent out a star, now wanted him to die!

I want his brain to be removed alive, sent to the vast universe, tested by the Trisolarans, and sent the information back to Earth for a slim chance in the future!

Cheng Xin is really a naturally ruthless person, a selfish person, an old classmate is sick, and he doesn't even greet him when he meets, maybe in Cheng Xin's heart, he didn't do anything wrong.

Maybe Cheng Xin is very simple, just asking with a pure purpose, this kind of naturally indifferent person can easily achieve worldly success.

By human standards, when encountering a sick student, generally speaking, I will ask if I have gone to another hospital to see, and if there is a chance for treatment? Are there any other wishes that are not fulfilled?

Instead of just saying to him, we need you to die, do you want to, it's useful to me!

Yun Tianming, who was like a dead heart, agreed, because he wanted to see if this group of ruthless people could survive the end of the three-body problem, and among the seven candidates in total, Yun Tianming's performance was very good.

It's not just hate, it's love and hate, it's a very complex feeling, yin and yang are opposed, but it's also unified, and so is the feelings.

In the end, when Yun Tianming cut off his brain, Vader looked at Cheng Xin's face with a mixture of ease and panic, and then said to Cheng Xin:

"By the way, I forgot to tell you that your star was given by Yun Tianming!"

"What?"

Cheng Xin couldn't believe it, her image was about to collapse, and such a blow made Cheng Xin rush into the operating room frantically, but it was over together.

Cheng Xin killed a person who loved herself deeply, even if she didn't love Yun Tianming now, but her sense of morality made her heart extremely panicked and contradictory.

This is the first time in Cheng Xin's life that he feels indebted, but all this has gone nowhere. The ladder plan was still underway, and Yun Tianming's brain was sent into the vast universe.

And even more unfortunate, the probe carrying Yun Tianming's brain deviated from its direction in the impact of the space nuclear bomb and flew into the vast universe.

Things still have a turn for the better, Zhang Xuan pointed in the direction once, so that this detector was finally received by the Trisolaran, and the Trisolarans used their own technology, as well as all the technical information on the earth, to resurrect Yun Tianming, which was easy for the Trisolaran.

As the first technical experiment to try a living human body, after Yun Tianming was resurrected, because the three-body man's thinking was transparent, they detained Yun Tianming in solitary confinement.

The robot conducts basic interrogation and communication with Yun Tianming, and learns human strategies and thinking from him, so Tianming's life is simple and repetitive.

He is now a deception object used to test the deception methods of the Trisolarans to improve themselves, which is very precious.

Unlike humans, who need huge computers to study the brain, the Trisolaran can use Zhizi to directly detect Yun Tianming's brain.

When the three-body person says what he thinks is a lie, a signal will flash out of Yun Tianming's brain area, so that even if Yun Tianming gives a deceptive answer, the three-body person can make a fair judgment.

There are not many such exchanges, because most of the time, the Trisolaran is conducting a questioning test. The Trisolaran people have their own duties, and only a few people will take time out to train lies, but this kind of training is not fast.
