The next few jumps were lackluster. Pen? Interesting? Pavilion wWw. ｂiquge。 info This is because the space has entered the area before the spiral arm, and the interstellar matter is thin, and there is no civilization or energy-rich planet.

The Milky Way galaxy has hundreds of billions of stars and hundreds of billions of planets, but they are all concentrated in a few spiral arms, not that there is no matter before the spiral arms, but the spiral arms belong to the thin belt of matter, and there are relatively few star systems.

So after the jump, the space basically did not stop, and when it was ready, it made the next jump, so in just three days, the space space sailed tens of thousands of light years.

"Li Yu, I have a proposal, in the next thousand light years, let's stop using a jump engine, let's use a faster-than-light engine!" Lin Wanbai suddenly said to Li Yu when Xiao Wei was ready to jump.

Li Yu looked at Lin Wanbai puzzled, with a faster-than-light engine? Now the faster-than-light engine of the Space has reached a thousand times the speed of light, a thousand light-years, that is, less than a year, which is already very fast, but for the plan made for this voyage, time will be seriously overtimed.

Seeing that not only Li Yu was puzzled, but even Fang Qianmo was also looking at himself curiously, Lin Wanbai couldn't help but say depressedly: "I had a feeling just now that there are things in front of us that are useful to us, and if we use space jumping to move forward, we will miss it." ”

Li Yu listened to Lin Wanbai's words and suddenly realized, it turned out that this was Lin Wanbai's premonition again, which did not say, even if the return time was delayed, he had to go according to Lin Wanbai's words.

"In that case, let's do as you say! However, we need to make some preparations before we go. Li Yu said to everyone.

Fang Qianmo was puzzled when she heard this, what else do you have to prepare for? Space's faster-than-light engine has basically not been used a few times, and it has been overhauled a few times before, so there is no problem!

So Fang Qianmo asked Li Yu: "What else do we need to prepare?" Isn't there no problem with faster-than-light engines? ”

Li Yu said with a smile: "I am going to improve the performance of the space's faster-than-light engine, and the original plan was to return to the Moya base to do it again, and after Wanbai made a request, it was necessary to upgrade it in advance." ”

Fang Qianmo now understands that Li Yu has made new progress in the research of faster-than-light technology, but when did he study it? You must know that the faster-than-light engine technology of the Space has contributed to both her and Wanbai.

"Have you made a new breakthrough in the research of faster-than-light flight technology? Since I came out, I haven't seen you specialize in research! ”

Regarding Fang Qianmo's question, Li Yu waved his hand slightly: "I haven't studied it specifically, it's just that I have a new idea when I was studying energy, which can be used to upgrade the faster-than-light engine." ”

Now, Fang Qianmo has no problem.

"How long will it take?" Lin Wanbai was worried that it would take too long for Li Yu to upgrade the faster-than-light engine, knowing that staying in the empty Universe Space for too long would easily cause depression.

Moreover, Li Yu must not only upgrade and improve the faster-than-light engine, in the previous voyage, the engineering robots in the space have not rested, because Li Yu has new technologies researched from time to time, and then immediately applied them to the space.

When making a travel plan, there was no technical upgrade of the space at any time, but when Li Yu found that the small-scale technical upgrade of the space did not affect the voyage of the space, he began to continuously improve the space, and at most, the engineering robots that came with the space were insufficient, and Xiao Wei urgently made a batch to meet Li Yu's needs.

Sure enough, after Lin Wanbai asked this question, Li Yu's answer was not unexpected, "It is estimated that it will take half a month, in addition to upgrading the engine, some of the functional modules of the space number also need to be upgraded, such as detection modules, defense modules, communication modules, etc., just to apply the technology accumulated during this time." ”

Half a month is not too long, and the space design time takes into account the need for long-term navigation in space, so there are not many entertainment functions, and if you are bored, you can also do experiments in the laboratory.

Speaking of doing a laboratory, Fang Qianmo has a question: "Li Yu, in addition to what I said earlier, do you have any plans to upgrade the experimental equipment in the laboratory?" ”

There is a reason why Fang Qianmo asked, Li Yu has new research results, she and Lin Wanbai also have research results, including some achievements on experimental equipment.

"There is no immediate use of this, only some long-term research, and the results of the stage are not suitable for immediate use. Do you have research results in this area? ”

"Of course there is, Wanbai and I are not here to travel." Fang Qianmo proudly straightened her chest and said loudly.

"In that case, Yui, where is the nearest galaxy?"

"Li Yu, the nearest galaxy is a hundred light-years away from us, do you want to go there?"

Xiao Yui projected the situation of that galaxy, which had one star and three planets orbiting around it, all of which had no life.

The resource map on these planets is also marked by Xiao Wei, it can be said that this galaxy is a galaxy with few resources, and the main composition of several planets is rocks, the content of metal elements is low, and the content of rare elements is even lower, and there is no development value at all.

It's just that for the space, the resources of this galaxy are enough, plus some rare elements collected in front of the space, which can fully meet the resources required for this space's technical upgrade.

"Then this galaxy!" Li Yu then analyzed the galaxies around the space, and decided to go to the galaxy that Xiao Wei chose.

The location of the space is exactly the thin belt of matter, and the distribution of galaxies is extremely rare, except for the galaxy chosen by Xiao Wei, the nearest galaxy is eight hundred light years away from the space, which is not as good as the one selected by Xiao Wei.

Changing the jump target, Space came to the nearest galaxy.

"What a barren galaxy!" Coming to the third planet, Lin Wanbai sighed.

"If there is no life, what does it matter if it is barren or not?" Fang Qianmo didn't understand Lin Wanbai's concern.

Instead of landing on the planet's surface, the space spacecraft remained in the planet's synchronous orbit, and a large number of mining robots were sent to mine the mineral points detected on the planet.

At the same time, the construction of modular factories began. The efficiency of the apostle-level robot is less than double that of the previous generation of robots. The extensive use of biometal has first improved the strength and flexibility of the robot's skeleton material, which can make more movements.

Just one day later, the factory was built and the mining site was up and running. After the initial processing, the primary product is transported to the space number for further processing.

The development of laboratory technology has made the process of primary extraction and smelting of materials much simpler than the most advanced technology on the planet.

Not to mention the mining of ore, anyway, there is no one on this planet, and the robot has adopted an extremely violent mining method, and by the time of preliminary smelting, the ore has been crushed into nano-level powder.

During smelting, the force field separation technology and element separation technology can perfectly separate the target elements, and the purity of the elements can reach more than nine nines.

After the elements are separated, they will be sent to the space number for the next step of processing, which is a refined process that can be processed into various materials that Li Yu needs.

The set of mineral preliminary treatment process researched by Li Yu can process millions of tons of minerals per day, and the area is not more than 10,000 square meters. Basically, you can feed in the raw materials at one end and produce the product at the other end.

The mainstream mineral smelting process on the earth is as high as seven main processes, which are divided into different plants. Li Yu only needs one.
