After dawn, the monsters that were rushing in the wild returned to the surface in droves and disappeared.

Their number is so large that it is estimated that it will not be less than 100 million. Although some monsters were killed during the night, it did not attract the attention of other monsters.

Somewhere about a few hundred kilometers away from their place of residence, five mechs collected the corpses of nearby monsters that had been killed, and roughly counted, the number was no less than a hundred. Next to this mountain of corpses, the heads of hundreds of fierce beasts were thrown here indiscriminately. There was no meat on the skull that could be used, but at Yun Yi's request, several people still picked it up.

Soon, under the control of Sakura, the spaceship descended here, and several mechanical arms stretched out from the hull of the ship, loading all the corpses and heads into the ship.

This is where there are benefits of large means of transport. If you only rely on a few mechs to carry it, you will probably be tired and half dead.

When the corpses of the more than 100 giant beasts were returned to their residences, all the residents came out to watch. Watching the corpses of giant beasts being grabbed out of the warehouse by the mechanical arm and piled up in the open space in front of their residences, these residents all showed incredible expressions.

You must know that in the past, relying only on those three mechas, they were usually busy for half the night, and they might not be able to catch a fierce beast. It's not because these drivers' skills are not good, on the contrary, their skills are extremely good, and they have been fighting with fierce beasts for a long time, and their skills have been honed very well. It's their broken mechs that stand in the way of their development.

These mechs have been used for five years in a row, and the replacement of spare parts is removed from other mechs, and the armor plates on the mecha are almost all gone, and there is no protection at all. Therefore, they must always be careful in battle, as long as they receive any heavy hits, they may let the mech be scrapped. Once the mechs are scrapped and unusable, they will lose their source of food, and the result will be that everyone will starve to death one by one.

And Yunyi and Xilufeth don't have to care about this, on the one hand, their mecha are all in good condition, especially Yunyi's, which is a personal mecha built with a lot of money. The second aspect is their cultivation, two innate third-level masters deal with these fierce beasts, it is like chopping vegetables, simple and easy.

Seeing Yun Yi step out of the mecha, Santan immediately greeted him, his face like a flower blooming.

"Your Excellency is so powerful, you can kill so many monsters in one night. If we were to do this, it would take months. ”

Yun Yi smiled slightly: "Wait a few days, I'll get you some new mechas, so you don't have to worry." ”

Hearing him say this, Santan immediately said in surprise: "Really? If there were new mechs, these monsters wouldn't be easy to capture. I don't have to go hungry anymore, thank you, sir. ”

Yun Yi sighed, when he visited the warehouse yesterday, Yun Yi saw that their food was very small, and the stock in the huge warehouse was only enough for them for three days. That's why he moved his mind to hunt and kill the beasts, and it just so happened that he needed these brains, and they needed meat, which could be regarded as helping them.

Immediately after removing all the carcasses of the beasts from the cabin, someone manipulated the engineering mecha to divide the corpses and obtain the usable parts from them. These engineering mechs were all unloaded from the ship by Yunyi, and cannot be used in combat, but it is still easy to disassemble the corpses.

After a busy night, Yun Yi excused himself to rest, said goodbye to Santan, and returned to the ship.

However, instead of resting, he went to the cabin. Here, the heads of more than a hundred ferocious beasts are piled up.

The process of obtaining the brain pulp is not complicated, under the control of [Sakura], countless metal tubes are inserted into it, and soon the milky white brain pulp is quickly sucked out and stored in a special cabin.

The skulls of these beasts are very rich in cerebral plasma. Yun Yi estimated slightly, just the harvest from last night, plus the kind of activation liquid from the Dragon Slayer Society, was enough to allow him to work for more than two years on those divine stones that he had brought back from the Death Shatter Star. In the evening, Yun Yi plans to make another trip to get enough activation liquid for five years at once.

Moreover, Yun Yi also plans to bring a large amount of beast meat back. He had considered that it was not practical to send the orphans here, and that this was also under the control of Iserras anyway. It's not safe here until you get the hang of it.

With the dual promotion of brain pulp and animal meat, Yunyi can imagine that it only takes two to three years for those talented children to grow up rapidly among the orphans adopted by Blue Sky. At that time, there will be tens of thousands of mecha masters under him! With them as the backbone, Yunyi will prepare a mecha cavalry regiment that focuses on mecha combat, which will be the largest force in his hands.

Speaking of the mecha cavalry regiment, as far as Yunyi knows, few countries have the ability to build such a team. First of all, their main means of combat is mecha, which requires mecha warriors to have a good cultivation level and mecha skills. In addition, the mechs needed by the mecha regiment are quite expensive, and the average country simply does not have the strength to form such a team. In addition to mechs, motherships capable of loading a large number of mechs, as well as warfleets and logistics teams, are also required, which is again an expensive expense.

In the Southern Universe, only Chu Tang's Royal Dragoons and New America's Griffin Special Mecha Regiment are on the bright side. Other countries, even the Federation of Lekima or Leland, do not have such an establishment.

It is said that the number of royal dragoons is thirty thousand, while the number of the Griffon Special Mecha Regiment is twenty thousand.

However, Yun Yi guessed that organizations like the Dragon Slayer Society or Paradise Island definitely had a powerful mecha cavalry regiment. After all, their population is relatively small, and it is very impossible to form a fleet, and they can't find so many ship operators, so it is better to form a mecha cavalry regiment.

Thinking of the money needed to form a cavalry regiment, Yun Yi couldn't help but shudder.

The biggest expense of the cavalry regiment is mecha. Although this kind of mecha is a standard mecha, it is different from those produced by Weilong or Nebula. The materials they use are extremely precious and precious, and they are no less valuable than personal mechs. Such a cavalry regiment sacrificed the flexibility and mobility of individual soldiers, but was able to win with discipline and superior attack power.

A mecha cavalry regiment composed of 50,000 masters above level 10 is enough to compete with 50,000 warships!

However, the cost of 50,000 mechs is much more than the total number of mecha fighters connected to 50,000 warships......

In Chu and Tang, 50,000 warships and supporting mecha fighters were being built, and if the personnel were not counted, the military expenditure allocated by the Imperial Military Department was 100 billion. But a cavalry regiment with 50,000 mechas, even if standard mecha can be mass-produced with a production line, one mecha needs more than 4 million, and 50,000 mecha will cost 200 billion! Coupled with the attached motherships, warfleets and logistics fleets, it is impossible to take it without 250 billion.

Looking at the number on the screen, which was calculated by [Sakura], Yun Yi could only smile bitterly and shake his head.

A knight of 50,000 mechs? Forget it, that's not something you can build right now. For the specific situation, let's wait for three years to see how many people can reach level 10 or above.

For now, let's work hard to make money!

Putting these unrealistic thoughts behind him, after practicing for a while, Yun Yi returned to his room and fell asleep.

Over the next few days, Cloud Wing slaughtered hundreds of monsters again, filling the warehouses of the settlement and the ship's warehouses with meat and brains. began to lead the ten engineering mechs to carry out simple excavation of the surrounding mineral deposits.

The locations they chose were expensive and easy to mine, and they were basically open-pit deposits. Engineering mechs exploit these deposits extremely quickly, producing at least thousands of tons of ore per day. Once the ore is excavated, it is randomly stacked near the mine, waiting for the ship to transport it back to the settlement.

After a week of tireless work, the new underground base was finally built.

The new site will connect the previously excavated settlements to form a vast underground space. Various passages and living rooms, as well as warehouses, restaurants, canteens, training grounds, etc., were opened. The new underground base is ten times larger than the original settlement, and it is not only an increase in scope, but also a simple increase in security, life, and environment.

After visiting the new base, these people who were left here were moved to tears one by one, and they swore allegiance to Yunyi. After five years of hard life, it is enough for these people to have a safe place to live and enough food to move them. Even if you can't leave here for the time being, it's a sea change compared to before.

After the construction of the base was completed, Yunyi took Syrumis and left here in a spaceship, flying towards a coordinate. On the first day he arrived at the monster planet, he sent the materials he needed to Zheng Yichun and asked him to collect these things. Iseras is still relatively strict in the management of mecha and other materials, but Zheng Yichun directly contacted the rebels, these people have their own forces and channels in Iserras and several surrounding countries, and quickly raised all these materials, loaded three large transport ships and sent them to the coordinates designated by Yunyi.

Afterwards, the crew of the ship left in a transport boat, leaving only three large transport ships here. With [Sakura] here, there is no need for any crew at all, everything can be controlled and commanded. After unloading the supplies from the three transport ships and loading them with ore and animal meat, Yunyi left the area.

In the starry sky, four spaceships loaded with supplies gradually moved away from the planet and galloped away into the distance......
