The next few jumps were unremarkable. This is because Space has entered the area before the spiral arm, with thin interstellar matter and no civilization or energy-rich planets.

There are hundreds of billions of stars and hundreds of billions of planets in the Milky Way, but they are all concentrated on several spiral arms. It does not mean that there is no matter before the spiral arms, but there are only thin zones of matter between the spiral arms, and there are fewer star systems.

So after the jump, the Space Number basically did not stop. After being prepared, it made the next jump. Therefore, in just three days, the Space Number sailed tens of thousands of light-years.

"Li Yu, I have a suggestion that in the next thousand light years, we should not use the jump engine, but use the super light speed engine!" Lin Wanbai suddenly said to Li Yu when Xiao Wei was ready to jump.

Li Yu looked at Lin Wanbai in confusion and used a super-light speed engine? Now the super-light speed engine of Space has reached a thousand times the speed of light. If it is one thousand light years, it will be less than a year. This is already very fast, but for the plan formulated for this voyage, the time will be seriously timed out.

Seeing that not only Li Yu was puzzled, but Fang Qianmo also looked at himself curiously, Lin Wanbai couldn't help but say depressedly: "I just felt that there were things that were useful to us in front of us. If we were moving forward in space jumping, we would miss it."

Li Yu suddenly realized after hearing Lin Wanbai's words. It turned out that this was Lin Wanbai's premonition that worked again. He didn't say that, even if he delayed the return trip, he had to follow Lin Wanbai's words.

"Since that's the case, then let's do what you said! However, we have to make some preparations before departure." Li Yu said to everyone.

Fang Qianmo was puzzled when he heard this. What preparations should be made? The Space Number's superluminal engine has basically not been used several times, and it has been inspected a few times, so there is no problem!

So Fang Qianmo asked Li Yu: "What other preparations do we need to make? Isn't there any problem with the superluminal engine?"

Li Yu smiled and said, "I am going to improve the performance of the Space Number's superluminal engine. I originally planned to go back to the Moya base and then carry out it. After Wanbai made the request, it is necessary to upgrade it in advance."

Fang Qianmo now understood that Li Yu has made new progress in the research on superluminal speed technology, but when did he study it? You should know that both she and Wanbai contributed to the superluminal speed engine technology of Space No. .

"You have made new breakthroughs in the research on superluminal flight technology? I haven't seen you specifically research it since I came out!"

Regarding Fang Qianmo's question, Li Yu waved his hand slightly: "I haven't studied it specifically, but I have new ideas when studying energy, which can be used to upgrade superluminal engines."

Now, Fang Qianmo has no problem.

"How long does it take?" Lin Wanbai was worried that Li Yu would take too long to upgrade the super-light speed engine. You should know that staying in the empty space for too long can easily cause depression in his heart.

Moreover, Li Yu certainly not only upgraded and improved the superluminal engine. During the previous voyage, the engineering robots in the Space Number did not rest because Li Yu has developed new technologies from time to time and then immediately applied them to the Space Number.

When formulating a travel plan, there was no technical upgrade to the Space Number at any time. However, when Li Yu discovered that the small-scale technical upgrade of the Space Number did not affect the Space Number's navigation, he began to continuously improve the Space Number. At most, the Space Number's own engineering robots were insufficient, and Xiao Wei urgently created a batch to meet Li Yu's needs.

Sure enough, after Lin Wanbai asked this question, Li Yu's answer was not beyond her expectations. "It will take half a month. In addition to upgrading the engine, some functional modules of the space number also need to be upgraded, such as detection modules, defense modules, communication modules, etc., which just make the technical applications accumulated during this period."

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

Speaking of laboratory work, Fang Qianmo has a question: "Li Yu, besides what I mentioned earlier, do you have any plans to upgrade the laboratory's experimental equipment?"

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

"This is not available immediately. There are only some long-term research. The phased results are not suitable for use immediately. Do you have research results in this area?"

"Of course there is, Wanbai and I are not here for a trip." Fang Qianmo proudly raised his chest and said loudly.

"In this case, Xiao Wei, where is the nearest star system?"

"Li Yu, the nearest galaxy is one hundred light years away from us. Will it pass?"

Xiao Wei projected the situation of that galaxy. There was a star in this galaxy, and there were three planets orbiting it, and none of them had life.

Xiao Wei also marked the resource map on these planets. It can be said that this galaxy is a resource-scarce galaxy. The main composition of several planets is rock. The content of metal elements is relatively low and the content of rare elements is even lower, and there is no value for development at all.

However, for Space Number, the resources of this galaxy are enough. Coupled with some rare elements collected in front of Space Number, it can fully meet the resources required for this space number technology upgrade.

"Then let's get this galaxy!" Li Yu analyzed the galaxies around Space Number and decided to go to the galaxy that Xiaowei chose.

The location of the Space Number is exactly the thin zone of matter, and the distribution of galaxies is extremely rare. In addition to the galaxy chosen by Xiao Wei, the closest galaxy is 800 light years away from the Space Number, which is not as good as the one chosen by Xiao Wei.

After changing the jump target, Space Number came to the nearest galaxy.

"What a barren galaxy!" Lin Wanbai sighed loudly when he came to the third planet.

"There is no life, what does it matter whether it is barren or not?" Fang Qianmo didn't understand Lin Wanbai's focus very much.

Space did not land on the surface of the planet, but stayed in the planet's synchronous orbit. A large number of mining robots were sent to mineral points detected on the planet for mining.

At the same time, the construction of modular factories has also begun. The work efficiency of apostolic robots is less than twice as high as that of previous generations of robots. The large-scale use of biometals first increases the strength and flexibility of the robot skeleton material, and can make more movements.

Just one day later, the factory was built and the mining site was also started. The primary products after preliminary processing were transported to the space number for the next step of processing.

With the development of laboratory technology to the present, the primary extraction and smelting process of materials has been much simplified compared to the most advanced technologies on the earth.

I won’t talk about the mining of ores. Anyway, there are no people on this planet, and the robot adopts extremely violent mining methods. When it was initially smelted, the ore had been crushed into nano-level powder.

During smelting, force field separation technology and element separation technology can perfectly separate the target elements, and the element purity 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. This step is a refined processing and can be processed into various materials needed by Li Yu.

The initial mineral treatment process developed by Li Yu can reach one million tons of minerals per day, and cover an area of ​​only tens of thousands of square meters. Basically, raw materials can be fed at one end and products can be produced at the other end.
