Not to mention the revenge plan that Xia Xu had brewed in his heart, after about half a day's travel, the stars were getting closer and closer to them.

The faint glow of the red dwarf star appeared in their eyes, and the judgment made by the four seasons before was not wrong.

That's when they changed their orbit again, as Shiki spotted a planet nearby.

In order to descend on the planets, the four seasons and summer began to slow down.

Because there is no resistance in the universe, as long as it can be continuously accelerated, it is theoretically possible to approach the speed of light infinitely, but interplanetary navigation is not possible with continuous speed. Assuming that there are two planets separated by a light year, it will never take a little more than a year to fly from one to the other, because it takes a certain amount of time to accelerate from zero to near the speed of light, and the relative speed to the destination when reaching the destination must also be zero, so it needs a deceleration time, otherwise it will fly by in an instant, or it will crash like a mass cannonball. What determines this acceleration and deceleration time is the acceleration of the spacecraft, that is, the maximum output.

Therefore, in order to land safely and soundly, Shiki and Natsuo must first slow down, and how to determine when to slow down requires more calculations.

These knowledge are relatively basic aerospace knowledge, and they have been learned in all seasons, so it is not difficult to calculate.

If it weren't for the discovery of that Macorss and the Fold technology in this world, I am afraid that it would be in such an astronautical stage.

Soon the planet came into view, a very desolate planet, about a little larger than Mercury, with craters and craters all over the surface.

After a while, they landed on the surface of the planet, which had no atmosphere, and its extremely low gravitational pull prevented it from grasping the atmosphere, so that the dark universe could be seen from the surface.

Red dwarfs are limited in how much heat they can provide, and they are located on the side facing away from the Sun, plus there is no atmosphere to regulate the temperature. This makes the temperature on the planet's surface quite low.

It is almost certain that this is a place where most carbon-based life cannot survive, and no life of the same type has been found.

When it orbited, the four seasons roughly observed the surface of the planet, and no artificial traces such as probes were found on it, and it seems that this is really a place that humans have never visited.

"Looks like no one has been here."

Xia Xu also saw this, and she was not disappointed by this, after all, the Milky Way is so big, it is almost impossible to find artificial traces by going to one place by chance.

"Well, we need to find another way."

This is also within the prediction of the four seasons, and no artificial traces have been found along the way, which basically confirms that no one has been in this galaxy at all.

"Although the people of this world are all over the galaxy. But it can't really be everywhere. However, in terms of density, the closer you are to the center of the galaxy, the more people there are. ”

Xia Xu analyzed according to the background of this world. After the first interstellar war, humanity began a migration program for the continuation of civilization, and the most important thing is to set off towards the center of the galaxy.

"Without knowing the direction, I can only fly towards the center of the galaxy."

Looking up at the starry sky, it is easy to judge which direction the center of the Milky Way is.

"Hmm."

The same idea is true for the four seasons and the summer.

"But even so......"

"Even at the speed of light, I don't know how many tens of thousands of years it will take to get to the center."

This is the biggest difficulty faced by the four seasons and Xia Xu, basically even the middle circle cannot live for tens of thousands of years, and they are likely to be brought back by the system before they meet people.

Rather than this, it is better to live here, there is a star that is constantly providing energy, and they don't have to worry about the consumption of energy.

"So it's imperative that you regain the ability to jump in space."

Although his strength is stronger than that of the four seasons, he has the ability to specialize in Xia Xu's space jump.

"That's true."

Being able to jump in space can drastically reduce the sailing time. It also increases access to the range of human activities.

Shiki took out the demon book from his arms, and there was a lot of damage compared to his full state at this time.

"Can it be fixed?"

“…… I can't be sure if it's completely repaired, but if it's a chance to restore the ability to jump in space. ”

Shiki said after checking it out.

"Oh. By the way, is this a magic book? However, the space jumps you did before were very similar to the technology of this world. ”

"Yes."

Shiki affirmed Natsuo's thoughts.

There are many kinds of technologies involved in space. Each world is different, because the interference force of the system allows various otherworldly abilities to be used in other worlds, but if you want to study it, you can only use local technology.

Four seasons after coming to this world, he conducted research on Fold and Fold waves, which is one of several technologies that involve the core of this world. The current society is inseparable from them, and this is also the preparation for the four seasons.

After inspecting every part of the damage, Shiki found a place where it could be repaired. Because there is nothing on hand right now, it is mainly a place that can be repaired by magic alone.

"I need to be on the side of the sun."

"Do what?"

"Absorb energy."

Although the energy of the sun is not magical, the seasons can transform this natural energy, which is why they are close to the stars in the first place.

The two took off again, heading towards the other side of the planet.

"My sister is very sad, in fact, if you need magic, my sister can also make up for you~~~"

On the way, Xia Xu said suddenly.

"You can."

Shiki replied unwaveringly.

"However, space jumps require energy, and there may not be stars on the way to replenish energy, so you have to save as much as possible."

“……”

"What's wrong?"

The four seasons looked at the silent summer.

"It's really not cute~~~"

Xia Xu reached out and poked Shiji's cheek.

“？”

The four seasons couldn't understand what Xia Xu was dissatisfied with.

"But it's so serious, it's pretty cute."

“？”

It's not cute for a while, it's cute for a while, it's so hard to understand.

The four seasons were completely confused, and Xia Xu was very happy to see the four seasons confused.

It didn't take long for the two to come to the side facing the Sun, a planet with a very similar environment to Mercury, and even similar to the star, with only one side always facing the Sun and the other always facing away from the Sun. One consequence of this is that the temperature difference between the two sides is very large.

Red dwarfs emit far less heat than the Sun, but the side facing the star is certainly hotter than the backside.

First of all, solar energy is harvested here in all seasons. (To be continued.) )
