For Cheng Xin, a character who has also survived from the last universe to the zero cycle, Zhang Heng is not very familiar, but he is by no means unfamiliar.

Even, for a certain period of time, he wanted to try to influence and change this Virgin like the Grim Reaper, so that the final tragedy would not happen.

But it's a pity that he didn't understand at that time that the root of everything was not in Cheng Xin, everything was the choice of human beings themselves.

Besides, he didn't have much ability at that time.

He can't stop the choice of human nature......

The human performance drove Luo Ji out of the community, and it also made him not even have to sleep under the overpass......

Getting back to the point, after seeing Cheng Xin, Zhang Heng also stopped his follow-up actions.

Because, no longer necessary.

Since this battle star is also human, and it is still a human led by Cheng Xin, then he did not dare to continue to have a series of interests in it before.

Is it too tired to let Cheng Xin join his own Enlightener faction?

Even today, Zhang Heng doesn't dare to underestimate her.

After giving up the idea of controlling the battle star, Zhang Heng's remaining targets were only those marginal civilization individuals who were captured by this human army.

As long as he shows up and asks Cheng Xin for these captives of marginal civilizations, Cheng Xin will definitely give it to him.

After thinking about it, Zhang Heng still chose this most direct method.

Moreover, showing up to meet Cheng Xin and asking for the captives of marginal civilizations is only one of them.

What's more important is that Zhang Heng also wants to use Cheng Xin to learn about the other people who have also survived from the last universe zero cycle, how is Yun Tianming and others doing now, and where are they......

However, Zhang Heng did not appear in front of Cheng Xin in a high-profile manner, but waited until there was no one next to her before the consciousness body appeared around her.

Cheng Xin is also an independent existence of the consciousness body, as soon as Zhang Heng's consciousness body appeared around her, and she didn't make any cover-up, she would naturally sense the existence of Zhang Heng's consciousness body for the first time.

"Who are you?"

After sensing the existence of Zhang Heng's consciousness body, Cheng Xin cautiously looked at the direction where Zhang Heng's consciousness body was located and asked.

Although this human civilization under her leadership, in addition to her consciousness and physical independence, there are several people who can also be conscious and independent.

However, the consciousness that appeared around her right now was not like the other people in civilization.

Then, it means that this unknown consciousness does not belong to the people of its own civilization, but from the unknown civilization.

"You're a consciousness from a marginal civilization?"

Thinking that her human civilization had just ended the war with the marginal civilization, she couldn't help but ask again.

However, when she thought about it, she felt that something was wrong.

Because, in the marginal civilizations of the current time period, their scientific and technological strength cannot even be made out of the small universe, let alone the independence of consciousness.

Therefore, this unknown consciousness cannot come from a marginal civilization.

Just when Cheng Xin was puzzled and was about to call the security forces below to drive away this unknown and unaware consciousness, Zhang Heng answered her with actions.

Since he has decided to meet with Cheng Xin, he must restore his physical body, otherwise Cheng Xin may not remember him again just because of the communication of consciousness and body.

When Zhang Heng recovered his physical body and Cheng Xin saw Zhang Heng's appearance clearly, Cheng Xin immediately stopped preparing to call for security forces.

She didn't recognize Zhang Heng at a glance, the reason why she stopped moving was just because Zhang Heng's physical body was also human.

"You're human too?"

Still, she asked more.

After all, the physical body can also be faked.

A life that has completed the independence of the conscious body will no longer be limited to its original body.

As long as you think about it, the body of any form of life can be used as a shell by the independent life of the conscious body.

Therefore, she also has every reason to suspect that it is a fake human who is in front of her at this moment.

"I'm pretty sure you don't belong to our human race, where are you from?"

Cheng Xin continued to ask.

If the other person can't answer, or the answer doesn't match what she knows, it's definitely fake.

After all, in the entire Three-Body Metaverse, how many branches of human civilization there are, not many people will know better than her.

Except for this one on the earth of the solar system, the others scattered in the three-body metaverse are all people who survived the zero cycle of the last universe, their descendants.

And those people, at the beginning of the current cosmic cycle, she has basically seen them.

Even if many years had passed, the branches of those she had seen might have changed a lot.

Perhaps, some of them have lost their origins.

However, historical information cannot be faked, even if you can't remember the specific origin, but the information recorded in history will also record what that civilization has experienced and in which galaxies it has developed.

Through this information, Cheng Xin can judge which one the other party belongs to in combination with the direction in which each team went when he parted ways with those people at the beginning.

"My name is Zhang Heng, take a good look at me, and think about it again, where do I come from."

At this time, Zhang Heng also replied.

"Zhang Heng?"

Hearing this, Cheng Xin also began to murmur the name on his lips, and tried to carefully recall when he had had deep contact with the person with this name.

However, after thinking about it for a long time, she still didn't think about it.

Although there are many people named Zhang Heng in this human civilization under her leadership, those people are basically ordinary people, and they have never had direct contact with her at all......

Seeing that she really couldn't think of it, Zhang Heng had no choice but to remind: "When you graduated from college, I gave you a model airplane at your graduation ceremony, and I also talked to you a lot......"

After Zhang Heng finished speaking.

At this time, Cheng Xincai's eyes finally widened, it seemed that Zhang Heng's reminder was useful, what did she really think.

"Big... University...... Commencement? ”

For a while, she didn't know if it was because of excitement or what, and her tone seemed a little hurried and roundless.

The word "university" is also a very old word for her.

When Zhang Heng hadn't reminded her, when she searched for memories related to this aspect, she didn't think about the previous universe zero cycle.

After all, she had seen all the lucky ones who had survived from the last universe zero cycle to the current cycle at the beginning.

But I didn't expect that there were other survivors?

"You ......"

When the memory was pulled back to the last universe to zero cycle, she finally remembered: "No, you, you are Professor Zhang?" ”

Professor Zhang, this was Zhang Heng's social identity on the earth at that time.

Although he was not a well-known scientist, he was not recognized by the mainstream intellectuals of the society at that time, thinking that he was just a person who relied on the face of the wall to become famous and cheated to eat and drink.

But it is undeniable that it still made a series of contributions beneficial to mankind when dealing with the three-body rebels and facing the three-body people at that time.

Many important projects also have the shadow of their participation.

Even, in the end, he was listed by the Zhizi of the Three-Body Man as a target who must be assassinated at the same level as Luo Ji.

The above is Cheng Xin's limited understanding of Zhang Heng at that time.

"I'm sorry, Professor Zhang, I failed your expectations and Dr. Luo Ji......"

But when she remembered that Zhang Heng also realized that she was facing the former elder at the moment, she was not happy at all, and the whole person behaved like a child who had done something wrong, and bowed her head deeply on her chest.

I especially remember that at the graduation ceremony at that time, Professor Zhang, who was not very well received but was not very famous, suddenly appeared in front of her as a little girl.

And also said that he came to congratulate her on her graduation and brought her gifts.

At that time, this was the second person she had met in her life, who gave herself a gift.

The first one was Yun Tianming, a classmate from this university before she graduated, who gave a star named DX3906.

However, this classmate Yun Tianming has always had a crush on her.

Now that Professor Zhang has suddenly given himself a gift, is it ......

It's no wonder that she thinks about it more, after all, Professor Zhang's fame at that time was great, but it was basically lace news.

Before Dr. Luo Ji, who was a wall-facing person, did not meet his wife Zhuang Yan, there were a lot of ridiculous things to do with this Professor Zhang.

I heard that especially for female college students like her, Professor Zhang likes it the most......

However, in the following conversation, she gradually discovered that although this Professor Zhang was indeed a little out of tune, he was actually not as unbearable as rumored.

And the motivation for giving her the gift was only because of her profession.

Since she is studying aerospace engines, the gift from Professor Zhang is an exquisite model airplane.

Although she couldn't say that she liked or disliked the gift, she accepted it anyway.

However, in the next words of Professor Zhang, she found that this gift was not as simple as a model.

"Do you believe that even though this is just a model of an airplane, if you launch it into space, it will immediately become a spaceship?"

"Even, with a few things, it's a spaceship that is faster than the speed of light?"

After giving the gift, Zhang Heng pointed to the gift and said.

"Professor Zhang, you're really joking, but I've just graduated, and I haven't returned the knowledge I have learned to the teacher."

"With our current human technology, faster than the speed of light?"

"How is this possible?"

Cheng Xin thought that Zhang Heng was just joking with himself, so he also retorted in a joking tone.

You must know that even the three-body civilization, which surpasses human beings a lot and has been giving humans a sense of oppression, their spaceships are only one-tenth of the speed of light at most.

At this speed, it will take 40 years to travel from the three-body galaxy to the solar system.

If it was so simple to surpass the speed of light, Zhang Heng and she might not have a chance to continue standing here and joking, and the Trisolarans would have already come over to kill the humans on the earth.

But Zhang Heng still had a serious expression and continued: "It's okay if you don't believe it now, but I hope that one day in the future, you will be able to recall what I said today, and verify this model to see if it will become a faster-than-light spaceship." ”

"If it can really become a faster-than-light spaceship, I also hope that when your personal thoughts can determine the future of the entire human civilization, you can take all mankind to fly into the universe on it as soon as possible."

At that time, when Zhang Heng said these words, he was like a god who claimed that he could meet the future.

It seems that it is also because I see the future that I will find her, a little girl who is still unknown and has just graduated from college.

But at that time, Cheng Xin felt that such a well-known professor had no reason to come to make fun of her.

So, he accepted the model with suspicion.

However, later she forgot what Zhang Heng had said to her today.

When she can really decide the fate of the entire human race for her personal thoughts, and therefore make the entire human civilization face a crisis, she can no longer remember where this model was thrown by herself.

In her opinion later, when Zhang Heng gave her this model, the curvature technology may have really been hidden in it, and it was still complete.

If she still retains this model, even if deterrence fails, humanity will still be able to gain a glimmer of life with it.

At the very least, there will be more people who can escape the blows of the two-way foil.

But she didn't know that without this model, humanity would still have a chance.

However, after more than 60 years of hard work, the only chance for humans to build a faster-than-light spaceship was still in vain!

In this way, no matter how many chances she is given, she can play it out.

In fact, when Zhang Heng gave her the model, he planned to escape the solar system.

Sending her a model to give humans one more chance to build a faster-than-light spaceship is also an attitude of treating a dead horse as a live horse doctor.

But the result was that the dead horse still failed to recover......

This is also why, now that Cheng Xin sees Zhang Heng again, and after confirming Zhang Heng, he will be willing to say sorry as soon as possible.

Because, Zhang Heng once left her the opportunity to bring the entire human civilization to her, but she lost it......

When she said "I'm sorry" in front of Zhang Heng at this moment, she was as sincere as she was in front of Luo Ji, who was already dying, during the last universe zero cycle.

But Luo Ji at that time said to her indifferently: "It's not you who is wrong."

chose to forgive her.

But Zhang Heng wouldn't say that.

However, with his current mentality, he will no longer dwell on what he once did.

Although the model he sent was indeed lost by Cheng Xin, this can no longer be blamed on all mankind, after all, it was not the choice of all mankind to ask her to get rid of it.

However, before she became a sword-wielder, she was really just an ordinary little human girl.

It also requires an ordinary little human girl to be mentally prepared to save humanity from then on.

Then since the person you sent the model knew that this thing could save humanity, why didn't he do it himself?

If you don't let others get on yourself, you blame others for your mistakes?

Therefore, the current Zhang Heng will not blame Cheng Xin, and he is not qualified to take responsibility for Cheng Xin in this matter.

After all, he was running away at that time......
