Three months passed like flowing water, and everyone in the huge cave devoted themselves to the development of the cave and the construction of their homes with great enthusiasm.

In particular, after the establishment of plantations and breeding ranches, and the realization of the base's own food supply, the complaints caused by the closure of the exit route were quickly quelled.

The mining of purple gold ore is very smooth, it is a high-value, high-liquid, high-grade metal with strong market demand, excellent energy conductivity, extremely versatile, stable price, no need to worry about how to sell it. After mining and preliminary refining, in the past three months, Song Lingyun's team has obtained more than 200,000 tons of crude purple gold.

"Mom, I'm going out for the next few days!" Before dinner, Song Lingyun informed Li Xuan.

"Where to go?" Li Xuan asked casually.

"Feite base, go to make a trade, Uncle and I will lead the team. In addition to selling the purple gold after three months of mining and refining, it is also necessary to purchase a large amount of various equipment. This matter doesn't need to be kept secret, so Song Lingyun said it directly.

"Well, I don't have to report what our family is going to buy. I'll make a list later, and you can follow the above to make purchases. Li Xuan said happily.

In the past, their mining team used to make a collective purchase once a month, but now they are only ready to purchase again in more than three months, and many families have a lot of things to buy.

For this mining team that wants to transform into a base, this procurement is a big deal, and everyone will not only sell the newly mined 200,000 tons of purple gold, but also take out more than eighty percent of the funds in the base account.

This is not 80% of the base's public funds, but 80% of the federal currency that everyone can use, which is more than 12 million yuan. In addition, the value of purple gold ore is about 16 million yuan, which can basically meet the large purchase.

Eight million of them will be used to purchase 50 1-star battle mechs and 2 2-star mechs, plus related energy blocks and scattered weapons. 20 million are used to purchase engineering mecha for mining, a set of small signal receiving towers directly connected to the Ziyao Federation Interstellar Optical Network (referred to as Star Network), and a set of medium-sized automatic smelting equipment.

These are all purchased by Song Lingyun. Song Tianwei is responsible for pulling people into the gang, fooling the small mining teams and retail investors who have dealt with him before, and some friends have joined in to strengthen their strength.

They used to be equivalent to temporary workers, Song Lingyun and their large mining team are willing to take them in, and those small teams and retail investors who are hungry and full must flock to them, hugging their thighs and begging for support.

However, this number is far from enough to support the ambition of establishing a base city, and Song Tianwei can recruit a thousand people at most, so this time Song Tianwei will also inspect the "black households" that recruit at least 3,000 people in order to meet the needs of employment at this stage. That is, those criminals and their descendants who do not have a hukou in the Obsidian Federation, or are exiled to this planet.

They don't have a formal identity, so life and death are up to heaven, as long as the force is enough to suppress them, Song Lingyun and they can pay a lower price for hiring.

Of course, if the force is not enough, it will be dangerous.

Compared with these, in fact, Song Lingyun's personal wealth is more valuable. However, for Song Lingyun, who wanted to set up a laboratory and buy a top-of-the-line 2-star battle mech, the value of this cargo was barely enough.

After all, as a member of the base, Song Lingyun plans to lend 10 million of them to the base for this public procurement.

This time, Song Lingyun used the dozen or so 1-star mutant beasts he had killed in the past three months of hunting, as well as the scattered spiritual materials he had harvested, to make a lot of magic weapons.

These include three replica sets of 1-star armor, as well as 14 psionic weapons that can be integrated into the body, worth more than 30 million.

The main thing is that the weapons made by Song Lingyun basically break through the overrun effect, and they can temporarily burst out with a 2-star effect of more than 100 degrees, which is very precious.

Of course, these weapons, of course, the earth buns on this planet can't afford to buy, and Song Lingyun's target is the high-rollers on the Star Network.

Song Lingyun can pay about 5% of the proceeds to ask the bank located in the Fit base to make a guarantee, issue an appraisal, and then auction it on the international network of the Ziyao Federation Star Network. In this way, buyers are not even limited to the Obsidian Federation, but also many other civilized people to ensure that the benefits are maximized.

More than thirty transport-type spider mechs walked along the mine, and Song Lingyun drove a combat mech in full armor to lead the team to stand on the first mecha of the team to escort it.

In the mines, danger can happen at any time. It could be a mutant beast or an attack from humans.

For some people, they prefer to use weapons to plunder the fruits of other people's labor, even if it is more dangerous, than hard mining.

In terms of the distance of the mine, the giant cave discovered by Song Lingyun - Leiguang Base (official name) is more than 10,000 kilometers away from the Feite Base.

The Spidermech travels at a speed of 800 kilometers per star hour, so it takes about 15 star hours to reach the Feite base.

The road was calm, and even after approaching the Feite base for 2,000 kilometers, they successively met several teams that also went to the Fitte base to trade, and everyone opened a certain distance to travel together.

Unlike the giant cave where the Thunderlight Base is located, the Fit Base is only five kilometers above the surface, and it is expanded on the basis of a natural cave, and then filled with dozens of scrapped spaceships, turning it into a small base with a radius of three kilometers, 1,200 meters up and down, and divided into twelve floors.

With a permanent population of more than 50,000 and a floating population of more than 80,000, it is currently the largest base on the planet, and the only legal base, with a number of official institutions, including the only public security administration, and the largest armed group.

Therefore, it is an orderly society and relatively safe.

Before entering the base, Song Lingyun and others parked the transport mecha in a warehouse built on the periphery under the command of the central light brain, with a rent of 18,000 yuan per day.

As for those who want to enter the trade, they are not allowed to bring any external weapons, whether it is a mecha, a particle lightsaber or a laser gun, it will be easily detected.

Only psionic weapons such as armor are allowed to be carried in because they are integrated into the body.

Of course, if you bring an intermediate mecha of 4 stars or above, it is naturally equipped with a space wrist wheel, which can still be carried into the Feite base.

For the first time since he had traveled to this world for more than three months, Song Lingyun had felt the familiar brilliance of civilization for the first time.

Inside the base, artificial light sources are lit up everywhere, completely imitating natural sunlight, and the light, temperature and humidity that are most suitable for the human body are refreshing and pleasant, as if you are completely in nature.

Inside, it's like a small town, with familiar streets, houses scattered on both sides of the street, people coming and going, holographic projection signs hanging on shops, and advertisements.
