When Tomoko approached, Liang Bing's eyes instantly became full of vigilance.

After all, although the girl in front of her seems to be completely harmless, it is not really what it seems.

Rather, it was the Zhizi who locked the technology of human civilization on the earth at the beginning.

Besides, for her, this kind of thing like Tomoko, whether it is in the known universe or when the universe of money, has brought her a lot of psychological shadows.

Therefore, when she saw Zhizi coming, she couldn't keep calm anymore.

Cheng Xin was actually similar, and he didn't say a word solemnly after seeing Zhizi coming.

In the end, it was Guan Yifan who took the lead in asking: "What should we call you?" Tomoko? ”

"Hmm."

Tomoko nodded,

"Can you tell me, then, how much time has passed since we left you and arrived?"

Guan Yifan continued to ask.

After all, for the few of them, it was only a few hours before they left Blue Star.

Coming back again a few hours later, Blue Star had changed so much.

Even if he knew that it was the cause of the influence of the black domain, which caused the time error between the black domain and the black domain, he really couldn't imagine what kind of error it would be, and how much error it would have.

"There are 1339563.6 small three-body problems."

Tomoko replied.

A three-body hour is equal to about 53 minutes of human beings, and 1,339,563.6 three-body hours is about equal to about 103 years of human beings.

In other words, 103 years have passed since the three of them left and Yun Tianming brought Zhizi to Lanxing.

More than a hundred years have passed, and it is no wonder that this living area has been managed so well by Tomoko and robots.

But when I heard that the past hundred years and more than one hundred years were not the same as I imagined, Guan Yifan didn't know how to figure it out for a while.

I had to continue to wonder: "Why has it been more than a hundred years, and you who are in the Black Domain, shouldn't the time be very slow compared to us who didn't fall into the Black Domain before?" ”

Guan Yifan was very puzzled, after all, it was Blue Star who fell into the Black Domain before the three of them, no matter how it was calculated, the time that passed on Blue Star would not be faster than the three of them.

"Not really."

Zhizi shook his head, and then also explained to Guan Yifan: "In fact, it should be that the three of you fell into the black domain before the blue star, and the black domain spread from other parts of the universe, and if the blue star is the end, then the blue star will also be shrouded by the black domain that will spread at the latest......"

Although Tomoko's explanation still sounds a bit strange at first, it is no longer difficult to understand.

It can be said that the black domain spreads from all directions with the blue star as the central point.

At that time, Guan Yifan and the others were returning to the Blue Star, so they would naturally be shrouded in the black domain first.

That is, the short time when Guan Yifan and the others were shrouded in advance, more than a hundred years have passed on the Blue Star.

After more than 100 years of error between the two, the subsequent time is exactly the same.

After all, the Black Domain was also spreading at the speed of light, and after a short while, the Blue Star was enveloped in the Black Domain together.

And why couldn't that expedition team get in touch with Guan Yifan in advance and inform Guan Yifan that the Black Domain was coming towards the Blue Star.

The reason is also very simple, because there is a black domain between the two, and it is impossible for any substance to directly pass through the black domain.

If you fall into the black domain, you can only passively be shrouded in the black domain, and you can't enter or get out actively.

"You said that the Black Domain spread from all directions, so does it also mean that our front feet have only left our world, and our back feet have also been shrouded in the Black Domain?"

After understanding what Zhizi meant, Guan Yifan thought of this fatal question again.

"Possibly."

Tomoko replied, "If your world is close to here, and you don't have to go around an area that has been shrouded in the Black Realm before coming here from your world. ”

"Then, there is a good chance that your world will be in the center of this Black Domain spread."

After all, Zhizi doesn't know where Guan Yifan's so-called world is, so he can only judge it this way.

After hearing Zhizi say this, Guan Yifan also fell silent for a moment.

That is to say, no matter what, even if he doesn't return to Blue Star with Cheng Xin and Liang Bing, he still can't avoid falling into the black domain?

The difference is just that it will be more lively in its own world.

"Does the spread of the Black Domain have anything to do with you?"

It was only then that Liang Bing began to interject.

After all, before this, several people had suspected that the sudden spread of the Black Domain might be related to Yun Tianming's arrival.

"Nothing to do."

Zhizi replied very firmly, and she wasn't lying, if Yun Tianming knew that the Black Domain would spread here, or if she herself knew that the Black Domain would spread here, then she would definitely have informed Guan Yifan of the news when she asked the expedition team to send back the news before.

"Is this black domain spread related to the current mass loss on the blue star?"

Guan Yifan then asked, "Now that the mass on the Blue Star is passing, you must have noticed it too, right?" ”

"Mr. Robot just told you, what do you know?"

Hearing this, Zhizi continued to explain without hurrying: "Actually, as of the completion of the construction of our Three-Body Civilization No. 647 Small Universe, according to the observed state of the universe in the Three-Body World, no impact of mass loss has been found......

The Three-Body Civilization has built hundreds of small universes so far, which means that when they build the 647 small universe, there will be no mass loss in the large universe.

Of course, when the small universe is built, it is certain that the mass of the large universe will pass, but it will not be as obvious as the current blue star, and it can even be observed.

"The universe is closed, and the mass of the large universe flowing to the small universe of various civilizations is still in the large universe in essence, and it will eventually collapse with the arrival of heat death."

"What about after 647 is completed?"

At this time, Cheng Xin also asked.

However, this time, Tomoko's answer was unexpected by everyone: "I don't know." ”

She continued: "There is a group of intelligent civilizations in the cosmic civilization, much like the Zeroers, called the Return Movement, who try to stop the construction of the small universe and call for the return of the mass of the already built small universe to the large universe ......"

She also mentioned about Zero, but she really didn't know much about that as well.

But if the groups of intelligent civilizations calling for the return movement are real, then it is very likely that the spread of the Black Domain, and the mass loss that occurred with it, have something to do with them.

"Perhaps, we should stop thinking about this, we are not God."

After Zhizi finished explaining, he couldn't say why, Guan Yifan suddenly said a little helplessly: "Now that we can't leave the Blue Star, we are destined to spend the rest of our lives on the Blue Star, and it really doesn't make much sense to think so much." ”

"But we've had to think about what God wants for a long time, haven't we?"

However, Liang Bing is starting to get stronger.

Anyway, she just didn't want to be trapped here all the time.

Not only did she have to leave Blue Star, but she also had to leave this universe and return to the known universe.

The three of them sat by the creek until the moon turned into the sun.

Tomoko went to her own business, she seemed to like farming very much, day and night......

"By the way, what about Yun Tianming? Why didn't you see Tomoko mention him? ”

At this moment, the three of them finally remembered Yun Tianming again.

And, according to what the robot said before; Some of the people who came to the Blue Star before died of old age, and some of them left......

How did the people who left?

Can they escape the Black Realm?

Among the people who left, would Yun Tianming also be among them?

Thinking of this, the three of them got up almost at the same time and began to call for Tomoko.

"Come with me."

After understanding what the three of them meant, Tomoko didn't talk nonsense and motioned for the three to follow him.

Yun Tianming did leave an explanation on the Blue Star, but no one asked before, and of course Zhizi would not take the initiative to say it.

Until a few people followed Zhizi to a stone monument, where there was the last tenderness that Yun Tianming left to Cheng Xin.

At this moment, things seem to be back on track, if it is true that the three-body universe of the last zero cycle is real.

Cheng Xin, who returned to Blue Star, did not see Yun Tianming, but only received a gift left by Yun Tianming, a gift that was bigger than the planet, the 647 small universe.

The small universe No. 647 is also the small universe mentioned by Tomoko during the day.

It seems that although this small universe was built by the Three-Body Civilization, it is now owned by Yun Tianming.

The clear inscription on the stone is also presented in front of Cheng Xin: "We have spent a happy life, and we can avoid the collapse ...... in the small universe"

Later, there is some relevant knowledge on how to apply the small universe.

Seeing the appearance carved on the stone, Cheng Xin immediately couldn't help but start crying.

Although she doesn't know who Yun Tianming refers to by us.

However, it can indirectly prove that Yun Tianming will no longer wait for her.

Instead, I chose to spend my life with someone......

"Didn't you say someone left? Could it be that Yun Tianming is not among them? ”

Liang Bing looked at Zhizi and still wondered.

But Zhizi just shook his head slightly, and didn't say whether Yun Tianming really left, or whether he really spent his life with someone as he carved and said,

"What does it mean to be able to avoid collapsing in a small universe?"

Liang Bing continued to ask: "Can I understand that as long as you enter the so-called small universe, you can avoid all the disasters in the universe?" ”

"It can be understood that way."

Only then did Tomoko reply, "If you don't want to continue to live a stable life on the Blue Star for a period of time, through the small universe, you can also escape from the Blue Star shrouded in the Black Domain. ”

Hearing this, the eyes of several people exchanged views for a short time, and made a final decision, but Liang Bing still said: "I want to leave, but if you want to stay here, I will also stay and live with you for a while." ”

She said to Guan Yifan and Cheng Xin.

Guan Yifan is nothing, after all, I haven't known each other for a long time.

But Cheng Xin spent time with her, and I don't know how many times more time I spent with her and Kaisha as sisters.

Although most of the time she feels that Cheng Xin is very pitiful, she has always been like this, as long as she gets along with someone for a long time, she will have feelings for him, and she can't do anything to fly separately when a big disaster comes.

In the universe that was originally not known to Zhang Hengchao, she was also hung in a black hole in the end, which also indirectly proves this.

After Liang Bing's words, Guan Yifan also nodded slowly: "I am studying the large universe with a diameter of 16 billion light years, but I don't want to spend my life on this planet that is only more than 10,000 kilometers, let's leave." ”

His thoughts at the moment were the same as Liang Bing's, and he didn't want to spend his life on the Blue Star.

"Actually, I wouldn't advise you to do it so soon." But Tomoko said: "Now none of us can accurately determine the speed of time passing in the big universe, but we can be sure that at least tens of billions of years have passed since you entered the blue star, and then when you successfully passed through the small universe. ”

"For tens of billions of years, we didn't know what kind of environment the universe was, and we didn't even know that the universe was not three-dimensional."

"When the time comes, if you want to return to Blue Star again, it won't be as simple as leaving, at least not with the 647 small universe."

Tomoko suggested.

After all, staying on the Blue Star can spend a lifetime without worrying about eating and drinking, and if you go out through the small universe, it is very likely that you will not survive for a second in the large universe.

"Perhaps, you think, even if the big universe can't go out anymore, the small universe can still be produced for you."

Tomoko continued, "But if you think clearly, compared to the Blue Star, which is only more than 10,000 kilometers, the 647 S is no more than a thousand meters wide, are you sure to leave so early?" ”

"Isn't the door of the small universe able to move at the speed of light, can you find an environment where you can live?"

Guan Yifan continued to ask.

His so-called door is the spatial anchor.

"If you insist, look for it."

After the suggestion, Tomoko stopped persuading.

In fact, according to her advice, the best thing to do is to live a life you want to live on Blue Star first, and then go to the 647 small universe.

Don't think about going back to the big universe anymore, staying in the small universe is the ultimate choice.

Because, there are two possible futures for staying in the small universe.

If the regression movement is successful, the universe collapses into a singularity and a new Big Bang of creation occurs, and the new universe can be reached.

And if the return movement fails and the big universe dies, the small universe will definitely not die as fast as the big universe, and you can still spend your life in the small universe, and the small universe will be good at that time.

"If all the people in the small universe think so, then the big universe must be dead."

At this time, Cheng Xin said.

Hearing this, Zhizi immediately looked at Cheng Xin speechlessly, for her thinking speed, the conversation period could be as long as centuries.

It's hard to imagine that a software algorithm can produce such complex gazes and expressions, but she does it now, and she really does it.

Obviously, Tomoko's A software retrieved all the data since she became acquainted with humans, and this data has a time span of countless years, and all these memories are condensed in her gaze, sadness, admiration, amazement, blame, regret...... All kinds of complicated feelings are mixed together.

"You're still living for duty."

Zhizi said to Cheng Xin: "In a civilization, survival is the first need of an individual, and the second is responsibility. ”

"In the same way, in a universe, survival is the first need of a civilization, and the second is the responsibility."

"With the scientific and technological strength of today's human civilization and the three-body civilization, even if it develops to this day, it is barely able to survive, is it really necessary for us to bear the responsibility of saving the universe?"
