"Husband, is this the four-dimensional space? Why is it always white outside, and there is nothing?" Peng Sisi lay on the window of the spaceship, his face full of questions.

There are so many things that really exist in the three-dimensional space, how come you can't see anything in the four-dimensional space? Even if you can't see something in three-dimensional space, it's at least a bit of a four-dimensional thing, why is it still white after flying for a long time like now?

"Baby, the four-dimensional space is the dimension of time, everyone, everything, everything, their original time is different, only under certain conditions, each other's time has become the same, will see each other. Otherwise, everyone, everything, and everything are relatively independent in their four-dimensional space. ”

"For example, now, because I have set the flight program of the spaceship, the time of the spaceship and mine has become the same, so I and the spacecraft can exist in the same four-dimensional space at the same time. And baby, because the spaceship carries you, the time is also the same as me and the spaceship, so you are also in the same four-dimensional space as us. ”

"But those other things that have nothing to do with us, because they are different from our time, it is impossible for us to see anything but us. Song Bin relayed the reason that Krumty explained to him to Peng Sisi in one breath.

Every step of the manufacturing process of this spaceship was completed under the guidance of Krumty, so it is unimaginably advanced. For example, Song Bin doesn't need to operate this flight, he only needs to set the relevant procedures before takeoff, and the spacecraft will enter the automatic flight mode by itself.

There are two modes of flight setting, one is to set the destination, and then the spacecraft will calculate how far away from the destination and how long it will fly, and then start flying automatically.

There is also a mode where there is no destination, enter the time and direction of flight, and the spacecraft will choose the nearest planet to land after the set time arrives.

Song Bin set the first type at this time, and the first stop he chose was Mars, so far, in addition to the moon, the most explored by earthlings seems to be Mars.

Of course, robots were used to probe in the past, but Song Bin and Peng Sisi no longer need to breathe, so whether the atmosphere of Mars is suitable for humans or not, there is no difference between the two of them.

The only thing to pay attention to is the environment of Mars, if the situation is too bad, just drive the spaceship away when the time comes. After all, Peng Sisi is only the evolution degree of Huang Se's blood, and Peng Sisi's safety must be ensured.

"What you're saying is so mysterious that I don't understand it. What this time and that time, these should be what Krumty told you, don't tell me you understand. Peng Sisi glanced at Song Bin, who was now learning and selling.

Song Bin smiled awkwardly, he understood a fart, at best, he understood the literal meaning, knowing that only under certain conditions would each other's four-dimensional spaces coincide, and each other's four-dimensional spaces were relatively independent in normal times.

"Husband, do you think there really are Martians on Mars? Look at the previous reports, didn't it say that there is water on Mars, and there are some ruins of similar buildings?"

"Let's go up and take a look when the time comes, although a large number of photos and other information have been transmitted back to the earth, but machines will always be machines, no human flexibility and no human carefulness. If there are many things that are not found by humans and only by machines, many relevant details will inevitably be missed. Song Bin shook his head, he didn't think that there would be intelligent beings on Mars.

At least not now, and even if there were, it was extinct. As for how to exterminate it, that's not what Song Bin has to care about, anyway, they just came out to play, and they didn't come to do scientific research.

The two chatted for a while, and the spacecraft had already left the four-dimensional space, needless to say, they knew that it was already on Mars.

After all, Mars is not far from the Earth, the speed of light only takes 3 minutes at the closest time, and the speed of light is only more than 20 minutes at the farthest point.

Their trip to Mars didn't need to fly faster than light at all, it just opened the four-dimensional channel and flew at the speed of light inside.

After the spacecraft landed, Song Bin went out to explore the path first, he had a blood bar system, and if there was danger, he could return to the spacecraft in time.

Peng Sisi also wanted to go out and have a look now, but she was not a child and knew the danger, so she could only lie on the edge of the window for the time being, looking at Song Bin with burning eyes.

Song Bin stood on the surface of Mars, and although the blood bar system did not fall, he found that the radiation here was too high, and the gravity was extremely low. Therefore, he didn't want to risk letting Peng Sisi come out with him, so he turned around and shook his head in the direction of the spaceship, and then began to walk back.

Back on the ship, the two didn't leave. It's already on Mars, so how can you leave so easily. You can't go out, but you can satisfy your curiosity inside the spaceship.

After re-entering a command to slowly orbit the planet he was on and get as close to the surface as possible, Song Bin accompanied Peng Sisi to stand by the window and admire Mars.

After circumnavigating for a while, Peng Sisi saw that Mars was full of potholes, no plants and no animals, and immediately felt a little bored. After pouting, he returned to his seat.

"Then let's leave now and go to the next destination?" Song Bin also felt that there was nothing to visit on Mars, the key was that they couldn't go out, so they also decided to leave Mars.

After Peng Sisi nodded, Song Bin began to enter the command again.

According to a list of planets that may be suitable for human habitation before departure, the nearest one is about 21 light-years away from Earth, which is also the second destination set by Song Bin and the others.

It would not have been possible to fly at the speed of light this time, otherwise it would have been 21 years. Even at 1,000 times the speed of light, they would have to fly for more than 180 hours, which means they would have to fly for a week in four-dimensional space.

Fortunately, Song Bin built a super-gravity training cabin in the spaceship, otherwise, it would really feel like a waste of time.

Moreover, the spacecraft is in the four-dimensional space at this time, and nothing can be seen outside, and it can't even be curious about the cosmic environment.

Fortunately, the husband and wife walked together and had a companion for each other. When you're bored, play games, or train in a hypergravity training pod, or just snap a game.

In this way, the days passed, and just when the spacecraft prompted that it was about to reach its destination, Krumty suddenly warned Song Bin urgently: "Stop, stop." ”

"What's wrong?" Song Bin's reaction to Krumty was a little inexplicable, seeing that it was about to arrive, what was the situation if he stopped now?

"There are space fluctuations ahead, you listen to me, quickly stop the spacecraft and exit the four-dimensional space. Krumti's tone grew more and more anxious.

Song Bin didn't dare to slack off, the ghost knew how dangerous this spatial fluctuation was, neither of him nor Peng Sisi were purple blood evolutionaries, so it was impossible to ignore this sudden danger.
