Despite the long time that has passed, most of the facilities on this metal planet are as clean as new, and there is no sign of the passage of time.

Seeing this, Lin Fan had to sigh at the strength of that mechanical civilization, according to some information he got from the inheritance holy relics, he knew that that the mechanical civilization was only a little short of being able to reach the fifth level - the civilization of the gods, reaching this level of civilization, even if the universe was destroyed, it would be difficult for them to destroy, but unfortunately the difference between this step was a world of difference, but despite this, they still left traces that belonged to them.

As the super weapon of that mechanical civilization, the materials used in the construction of Wang Xing are extremely special, and any piece of metal here can be auctioned for sky-high prices in the auctions of some high-level civilizations.

However, although this king planet successfully survived the destruction of the last universe, the degree of damage it suffered is also very serious, although many equipment can still operate, but most of them are incomplete, and the functions are naturally incomplete, and if you want to repair this king planet, it is impossible to do it with the technology that Lin Fan has mastered now.

He walked around the planet, which was only a third of the planet, and had a clear understanding of the situation here, although most of the functions of the planet were incomplete, but there were also some complete places, such as a huge parts processing and production center, and an energy harvesting, synthesis, automatic machining center, and so on.

Among all the well-equipped factories and processing centers here, this energy harvesting, synthesis, and automatic processing center is the most powerful, and the strength to master energy harvesting in the chaotic galaxy is only those second-level civilizations, and the technology they master can only collect second-level energy, and the main source of energy is the sun, but this processing center can be different, it can collect and synthesize fourth-level energy, not to mention collecting energy from the sun in this kind of star, and even in a black hole.

In addition to equipment and factories, there are still a lot of materials in some databases, but unfortunately those materials are too advanced, he is not basic enough, he can't understand at all, it's like letting kindergarten children go to see the high math of the university, so now you can't use it, you can only look at it!

But even so, the research value of this planet is extremely high, if everything on this planet can fall into the hands of a planet that has not yet reached the first level of planetary civilization, then in a few years, the scientific and technological level of this planet will definitely have a leap forward.

This planet, even if some forces with a level of civilization that have reached the fourth level will rise up to fight for it, it is best not to leave this planet at present, otherwise Lin Fan will not be able to keep it at all.

Before you have enough strength to protect yourself, you must not divulge the secrets here, fortunately, there are many black holes around this planet, which usually do not attract the attention of other forces, and the route to reach here safely is not so easy to find, Lin Fan was able to come here because of the guidance of the holy relics in his body.

After thinking about it, he didn't plan to stay here for a long time, after all, the Han Empire was still facing the front of the Xinglan Empire, and the 20,000 new Sunstrider warships left at home couldn't resist for long, and he had to go back as soon as possible.

Although he can't show Wang Xing, some Lin Fan can now use some of the factories here to help him increase his strength, such as the factories here to help build those new Sunseeker warships.

In the meteorite belt near this star field, there are many open-pit deposits, coupled with a large number of "ordinary materials" stored on the planet, the processing plant that has been dormant for countless years was immediately activated, and the scale of the processing plant is very large, almost at the same time, there are more than 50,000 new Sunstrider warships under construction.

Lin Fan only needs to input the design drawing into the central optical brain, give the corresponding instructions, and the rest of the things will be automatically completed by the factory, only to see that in the factory, countless giant mechanical arms swing, take out the metal solution from the high-temperature and red-hot smelting furnace, and send it to a specific machine to go through a series of processes such as cooling, separation, slag removal, purification, etc., and finally become a piece of high-purity high-quality finished alloy!

After these alloys are sent to the processing plant, they are processed into parts that meet the specifications and installed on the warship.

The speed of these factory construction warships was extremely fast, it only took ten hours, and the first batch of 50,000 brand-new new Sunfighter warships had been built, and there were some differences between these newly built warships and the warships brought by Lin Fan.

The difference is mainly reflected in two aspects, the first is the armor defense, the second is the energy core, because in the process of building this batch of warships, there are a lot of ordinary materials in stock, so the defense of the surface armor of this batch of newly built warships is stronger than the energy shield!

In terms of energy core, when Lin Fan was inspecting the energy harvesting and synthesis automatic processing center, he found a batch of medium-grade energy spars, and in order to allow the battleship to use these energy spars, he made some modifications to the energy conversion device with reference to the equipment here.

Although the batch of spars obtained is only an "ordinary" grade spar, its grade, as well as the energy contained in the unit volume, has far exceeded most of the energy spars outside, and the most important thing is that this spar can also be used to charge the weapon system, in other words, the battleship has this energy spar, and there is no need to buy "ammunition" separately.

That level of energy crystal is different from the general spar outside, and it is a finished product that has gone through hundreds of complex processes such as quenching, purification, and concentration.

Just a fist-sized piece can consume a Sunstrider battleship for twenty years!

In the warehouse of this base, there are ten warehouses covering an area of tens of thousands of square meters, and when Lin Fan left, he also took these energy crystals out by the way.

Three days later, 200,000 brand-new Sunseeker battleships were neatly lined up in the starry sky, and if it weren't for the urgency of time, he was even ready to rebuild his 30,000 Sunseeker warships and 10,000 Tianwu Kingdom's main battleships.

However, because it has been more than a month since he left Dolan Star, and he didn't know what happened in this more than a month, so he was in such a hurry to go back, this time the main fleet in his hand together already had 260,000, and this kind of strength was enough to go head-to-head with the Star Lan Empire.

This huge fleet slowly left the Lightless Star Domain, and the process of leaving was even smoother than when it came in, because the black holes in the Lightless Star Domain themselves were part of the defense system of the King Star, and after the Wang Star consciousness body was awakened, it would naturally not let Lin Fan's fleet encounter danger in this Star Field.
