Just when the entire human social system was undergoing a major overhaul, the renovation project inside the spaceship was also not left behind. Ｘ

A large smelting center is working overtime to purify the mineral material and repair the "honeycomb structure" of the Noah using a variety of steels and alloys in stock.

Of course, people only patch some of them, and some voids don't need to be patched. According to some biologists, Noah's upper, middle and lower layers are greatly connected, which is conducive to the formation of large ecosystems. To this end, a large number of ecologists have specially formulated detailed transformation plans. If these techniques can be realized, real clouds and natural precipitation may form in Noah!

In addition, the ecosystem will be greatly improved, and the functional areas will be rebuilt, with additional buildings such as commercial areas, entertainment areas, and schools being built in addition to the existing residential and industrial areas.

Yu Yifeng sat in the captain's room, looking at a report, the construction of the thermal power station in the magma area was also progressing in an orderly manner......

There were quite a few difficulties in this regard, because the magma pile was in a high-gravity zone, which required a lot of new materials, and it was very hot, and the robots responsible for building it often went on strike......

However, after stumbling up, the first experimental thermal power station was finally completed in three months!

The first thermal power station with a power of about 2 million watts......

Yu Yifeng was not worried, but a faint joy filled his heart.

Not only him, but also many in the know, excited about the first thermal power station.

This magma is a valuable source of energy left behind by supernovae, and there are so many of them that it must be good to be able to use them. Human beings have never had too much energy, because it can be used to extract the living materials that people are short of.

For example, those oxides, from which oxygen can be extracted, and hydrogen, as the most abundant element in the universe, is also very easy to collect, and the two together are water.

People use various chemical, physical and other methods, as long as they are willing to consume energy, water, fertilizer, organic matter and other shortage materials can still be produced.

Yu Yifeng put these reports aside for the time being, and if he needed to reply, write "approve" and "agree".

Then he looked back at the scientists' reports.

There is nothing particularly surprising about the reports of scientists, but there are a lot of them.

Now people are in a very stable research environment, and there are no flying saucers and aliens coming out to disrupt the situation, so all kinds of research reports are emerging in endlessly.

Humanity finally has time for all kinds of scientific research activities!

Others, one of the reports particularly aroused Yu Yifeng's idea. This is a report given by the astronomical team, in which the direction of motion of the Noah spacecraft is roughly calculated.

Yu Yifeng's heart moved, this is very important news, without the resources of a planet as a backing, flying around in the universe is always an insecure thing......

The position of the Sun is located on one of the arms of the Orion Arm, roughly halfway between Sagittarius and Theseus, and it can be said that it is a backcountry.

According to this report, the direction of Noah's movement is exactly the direction leading to the centaur arm......

It also happens to be the core direction of the galaxy!

Judging from the current speed of motion, it is estimated that it will take one or two thousand years for Noah to run to the centaur arm, and if you count the relativistic effect of time, people will feel it in two hundred to four hundred years......

Seeing this, Yu Yifeng felt a little bad, and his brows furrowed......

A few hundred years is a long time!

Well, it doesn't matter what the Orion Arm or the Centaur Arm is. His main concern is whether he can meet a star or planet.

Normally, stars are accompanied by planets. As long as it is a terrestrial planet, humans can get resources from it. There is no shortage of resources or energy.

Their current shortage of resources is a bit like the situation of the Green Light People......

The trajectory of Noah's movement can be said to be a straight line, and with human ability, it can only change the direction of movement a little bit with a nuclear bomb; Of course, scientific research also uses the way of throwing materials outward to make it slow down or even stop......

It would be great if this trajectory could sweep the range of a star. Humans are perfectly capable of stopping a spaceship and slowly flying to a planet.

But if the course deviates from the star by 0.1 light-years or 0.01 light-years, human technology is somewhat powerless. Even a distance of 0.01 light years can allow Noah to fly for hundreds or thousands of years...... Whether you admit it or not, that's it.

"I happened to encounter a star in the flight path, this probability is very slim!"

Yu Yifeng also knew that there was little hope for this, although there were many stars in the Milky Way, most of them were concentrated in the center of the Milky Way.

For the nearby cantilever, the density of a star in one cubic light-year is less than one thousandth, how can human beings be so lucky?!

So the best thing to do is to use a nuclear bomb to slightly change the direction of Noah's motion, correct its direction of motion, and sail towards a closer star system.

But...... With such a high speed, how easy is it to change? The mass of the nuclear bomb dropped should not be too large, otherwise the speed of the entire spacecraft will be reduced due to the strange nature of the Noah.

"What a hassle......" he grabbed his hair and continued to read the report.

Because the Noah spacecraft is close to the speed of light, the particles in the universe can easily turn the scientific instruments that come out into space junk. Even if the probe hides on the back of Noah's direction of motion, coupled with a thick protective layer, it only prolongs the observation time, and it may be exploded by gamma rays from behind.

Scientists have made various attempts to observe the outside world. But the radio telescope damaged one, but the effect was not good.

Because the telescope can only see the stars on the back side of the direction of motion, but not the stars in the direction of Noah...... What's the use of that?

So much so that people can only roughly estimate their position based on the previous sky map, and 21.3 light-years away from Noah, there is a star system called "187J3X1", on which there are four planets.

According to Noah's current trajectory, the closest distance is about 0.67 light years!

0.67 light years, that's still too much!

Yu Yifeng frowned, a rough calculation would not work on this occasion, at that time, even if the distance was only 0.01 light years, it would be much beyond the human navigation ability.

Seeing this, he finally knew what this group of scientists wanted to do...... You have to use a gravitational-wave telescope to make accurate measurements and then make plans!

After all, gravitational wave telescopes are not looking at light that is coming and going, but at "waves" everywhere! It can easily "see" the parts that are obscured by the Noah.

But...... Isn't it too risky, what if this alien creature is blown up by high-speed particles?

Even the gravitational wave telescope cannot detect the outside world inside Noah, and must explore the universe.

If it is damaged, there is no way for humans to fix it, and if it does, it will be completely broken!

Yu Yifeng's face was a little cloudy, and he felt that he couldn't make up his mind.

"No, we have to develop high-strength defensive armor first, and we have to ensure the safety of the gravitational wave telescope. Gravitational wave telescopes must not be allowed to be damaged! ”r
