The Biosphere is not like a spaceship.

It's a huge, well-established world.

There are industrial areas, warehouse areas, and agricultural areas on the ground floor.

It even freed up a few floors of space on its own, planted high-quality pastures, transformed them into savannahs, and raised a large number of cattle and sheep, so as to provide the milk and meat that humans must need.

There are special tourist areas, and forests, lakes, beaches, and seas have been built to meet people's outdoor travel needs.

At the top of each layer of space, there is a weather simulation system, there are blue sky and white clouds, cloudy, dark clouds covering the sky, starlight, deep night sky, pitch black and other dozens of modes to choose from, although the height of the inner space of each layer is actually only about 20 meters, all kinds of weather, are simulated by the graphene film display on the roof, but the degree of reality is very high, can make people have a feeling of "thousands of miles of blue sky".

There are also a large number of luxury living areas, a large number of five-story western-style buildings, criss-crossing streets, large shopping malls, hospitals and schools, maglev highways and intersections, complete facilities, and no different from the city.

934th floor, living quarters.

Wei Yunfei has been a little sullen lately and feels unhappy.

This unhappiness has persisted since he stepped on the Biosphere and entered this spaceship.

"Mom and Dad, why are we leaving Mars? Why did my friend leave school, when everything was so good. ”

Wei Yunfei asked his parents this question more than once, but he never understood it.

"You're still young, kid, you'll understand later." Mother said softly.

"We want to go to a happier and better place, to find a more perfect home, where there is no strange gaze, no hatred and rejection, where there is only us, we will be free, we will be recognized and respected, and we can stand in the ...... of this universe"

His father muttered a lot in his ear, and his eyes were full of excitement.

But Wei Yunfei didn't understand.

He is only seven years old, and he has not felt hatred, rejection or the like, he only thinks that most of the classmates in the class are stupid and stupid, very cute, especially the girl named Xia Xueyan, he likes it very much.

Especially when the teacher asked each student what their dream was, Xia Xueyan said: "My dream is to marry the big hero of the galaxy on TV and become the wife of the big hero." ”

When it was Wei Yunfei's turn, he said without thinking: "My dream is to become a big hero and marry Xia Xueyan as his wife in the future." ”

"Hahahaha!" Teachers and classmates laughed.

Xia Xueyan had a red face and red ears, glared at him viciously, and ignored him for the next semester.

But this time, when Wei Yunfei was about to leave, Xia Xueyan gave him a handkerchief alone, and said in his ear with tears in her eyes: "If you really become a galaxy hero, I will marry you!" ”

"I'm going to be a hero!"

Wei Yunfei shook the handkerchief in his hand and swore secretly.

It's just that this exploration mission may take thousands of years.

After a thousand years, even if he works hard to become a hero, the girl he likes will either be old or married, how can they be together again?

"Most of the big heroes on TV don't have wives, and even if they have wives, they will often be captured by the villains."

Ay~

He knew, how could he not know that he had an IQ of 230.

But there was a seed planted in his heart.

He clenched his fists and said, "No matter what, I will keep my promise and become a hero for you!" ”

……

Four and a half years later.

The speed of the ecosphere number has reached the level of 0.75C.

It is located 3 light-years away from the main sequence stars of the solar system.

Since the nearest star is also 2.9 light-years away, the concentration of particles in the universe has been reduced to an extremely low level, no more than 100 per cubic meter.

Infinitely close to a real vacuum.

Even the starlight has dimmed a lot.

"Don't be under any illusions about finding any available supplies in such an environment."

Wei Ming scanned Xiao Hei for a long time and came to the conclusion that if even 1 kilogram of material could be collected in such a vacuum environment, it would be a miracle.

Immediately, the Ecosphere opened the strong magnetic field shield, using a strong magnetic field to block out the vast majority of cosmic particles.

Then Wei Ming took a group of personnel and boarded three C-class warships, and under the traction of Xiao Hei, at a faster speed of 0.85C, he ran forward for a month, and then completely covered it with the gravitational radius, and in a short time, the speed was reduced to 0.3C.

The location of the disappearance of the third group of migrant trains is about to arrive.

Considering that it was very troublesome to slow down the Biosphere, Wei Ming brought three C-class warships over in advance and deployed in advance, striving to investigate the cause of the mysterious disappearance of the third group of migrant trains within a week of the Biosphere catching up.

In other words, the time is only a short week.

As a matter of fact!

When Wei Ming scanned a strange curved space-time in front of him through Xiao Hei, he chuckled in his heart, and seemed to see a clue.

But by the time something was wrong, it was too late.

The three C-class warships all burrowed into the strange time and space ahead.

"The communication link is broken!" The system issues a warning.

"The biosphere signal could not be received, and the contact was interrupted." The Communications Officer said.

"What caused the outage, was it interfered with or was the communication equipment malfunctioning?" Zhang Xingfeng hurriedly asked.

"Neither! Both the signaling and receiving equipment are working normally, but contact with the mothership has been lost for unknown reasons. The communications officer said.

"How is this possible?"

Zhang Xingfeng shook his head: "How can the good end be interrupted, could it be that the electromagnetic waves are offset by unknown energy shielding, and this universe has not been covered, how did it do it?" ”

"You're right, the nearby universe is covered, and electromagnetic waves can't penetrate it, but only travel along its surface."

Wei Ming opened his eyes and said, "I feel it, we have entered a special time and space, no matter what speed and direction we enter, we will always move in a straight line in it, and we will never be able to run out. ”

"Linear motion, how can it not come out?"

An expert said: "No matter how big this universe is, if it moves in a straight line, as long as it is long enough, there will definitely be a day when it will run through." ”

"If it were a three-dimensional Möbius space-time, we really couldn't run out, but kept going around in circles."

Long Tianhao said: "I now understand why the third group of migrant trains mysteriously disappeared, it turns out that they encountered the cosmic ghost hitting the wall and were trapped in this Mobius space. ”

"Mobius space?"

Zhang Xingfeng immediately understood that the principle is the same as the two-dimensional Möbius ring, the three-dimensional Möbius space is one dimension higher than the two-dimensional, but it can easily trap humans in this space like trapping an ant.

Never get out!

"What to do? How can we get out and will we be trapped in this? ”

Immediately, someone panicked, shocked, and full of panic.
