This starry fortress was built on the border of the Seven Domains Federation, surrounded by a blank area, and there was no sign of other creatures in the vicinity of this fortress.

It's a man-made planet.

As the spaceship slowly approached, Yang Fan could clearly sense that the fortress was rapidly getting bigger.

At first, it was like a small steel ball, but it didn't take long for it to completely fill Yang Fan's entire field of vision.

"How big is this fortress?" Yang Fan was on the spaceship at the time to inquire about Clay Ford, who was near him.

The other party just smiled, and then reported a data, "10,000 kilometers." ”

This is a man-made fortress, 10,000 kilometers in diameter is definitely the size of some planets, I really don't know how much material this fortress will cost.

This fortress is different from the built-in structure of the planet, it relies on the rotation of the fortress itself to produce a large centrifugal force as a substitute for the gravity of this fortress, of course, the magnitude of the centrifugal force is specially calculated.

And the spaceship that Yang Fan is riding on now relies on the gravity maintained by its artificial gravity technology.

The gravity of different planets is different, in order to unify the norms, all the fortresses built by the army are designed to be the gravity of the administrative planet of the center of the Seven Domains Federation, and at the same time, any federation has a personal device for fine-tuning gravity, so that everyone can enjoy the same gravity conditions of their home planet on any planet in the Federation.

After the spaceship that Yang Fan was riding on entered the fortress, it would stay in the relevant berthing area as required.

Stepping on the ground of the fortress, Yang Fan didn't feel any discomfort at all, the gravity was the same as on the spaceship, as for the air, Yang Fan had already entered the second order, he only needed to have more than ten percent oxygen content, he could survive, and when he reached fifteen percent, he could live normally.

The damage to his body from toxic gases has also been minimized, except for certain viruses and highly toxic, he can be said to be invulnerable.

This fortress is different from ordinary planets, but because its demand is too great, it needs to build a super large ecosystem, and this also requires all kinds of creatures and talents, so in addition to the outermost steel fortress, there are mountains and rivers, urban people, flowers, birds, and beasts in its interior.

If the creatures of the natural planet live on a spherical surface of the planet, then the inhabitants of this fortress are a spherical surface living inside it.

The entire interior of the fortress is hollow, and people rely on centrifugal force to live on the inner surface of the fortress.

There is a fiery nuclear fusion reactor in the center of the fortress, and its power and all aspects are controlled just right, not simply to provide energy, the main role of this nuclear fusion reactor is to provide the energy needed for photosynthesis for those plants.

When it comes to energy, there are too many that can be used in the universe, but considering the evolution of living things, nuclear fusion is more suitable.

In this place, the top of the head is the other side of the world.

Yang Fan was directly thrown to this place by the lieutenant colonel, and there are a lot of spaceships coming and going here, after all, it is a fortress built in a blank lot, but Yang Fan must complete the task to repay his arrears, and at the same time, he also needs to make up enough money to go to the Starry Sky Avenue Field.

Fortunately, Yang Fan met a mercenary team on the spaceship, and they had a good chat with Yang Fan, and Yang Fan decided to do a mission with them, after all, in the universe, the power of one person is too small.

The reason why they can become friends with this group of mercenaries is because they are more similar in appearance, and Yang Fan has a sense of intimacy when he sees them.

"Yang Fan!" As he left, Clyford held Yang Fan in his mouth.

"Master, the other party injected you with a hundred cosmic coins!"

What the?

Yang Fan didn't know why he did this.

One hundred Cosmic Coins is not a small amount, even if he sails for several years and eats and drinks for nothing, he only owes less than a thousand Cosmic Coins.

Yang Fan's first reaction was to return the money to him.

"Haha, put the money away, you're poor now, and you'll have a chance to pay it back to me later, aren't we friends? Maybe I'll need your help in the future! ”

Not to mention the rest, Yang Fan of the other party's affection was recorded, and the two of them separated after leaving each other's communication messages, Clay Ford is about to continue his cruising trip, and Yang Fan needs to integrate into this universe as soon as possible, and his main thing at the moment is to take on a task that pays enough.

The fortress has a variety of facilities, and it is not so much a military fortress as it is a settlement in a remote part of the universe.

After staying here for about a month or so, Yang Fan's money was almost spent.

In addition to the materials produced by itself, many of them will also rely on external transportation, but the things transported from distant places are definitely much more valuable than those here, so the consumption is not ordinary.

Fortunately, when Yang Fan was about to take off his pants, the mercenary team he knew before found him.

"Yang Fan, we have found a good task, to help rescue the last surviving people trapped in Rao Aige Star, the commission is huge, up to 50,000 cosmic coins We have collected seventeen, plus you and two other guys, a total of twenty people, in the end, if it is divided equally, each person can get about 2500 cosmic coins, which is a lot of money!"

I don't know the name of the person who came to find Yang Fan, the code name is Smart, and he belongs to the technician in the original mercenary team.

His words made Yangfan very excited, but there was still a big problem with this matter, "The amount is so high, will there be a problem?" ”

"We have also investigated this matter, because that low-level civilization planet privately conducted some research on biochemical agents, and finally the leakage of the medicine led to drastic changes in the whole world, although the virus on that planet is very contagious, but it is not a problem for our technology at all, what needs to be considered is the huge number of the other party!"

Needless to say, the "smart brain" in the latter part is no longer necessary, for their strength, if it is just a simple accumulation of numbers, the threat is almost zero.

"How are we going to get there?" Transportation is not a trivial matter, in the universe, if you want to rush to a certain place but there is no suitable method, it is estimated that you will not be able to reach it even if you die.

"This is not a problem, the warship you took before was flying inside the space of the universe because of the need to cruise in some sections, and the time will be very long, we will directly teleport into a spaceship traveling in the dark universe route this time, and the estimated arrival time is within seventy hours, and the other party will pass through this section of the dark universe route in five hours."

"However, because the military department will send relevant teams to reset that planet at that time, and that planet has not joined the federal system, we don't have its specific coordinates, we need to issue specific space coordinates, and wait for the arrival of support troops!"

These didn't sound like a big deal, Yang Fan just thought about it briefly and agreed to the other party's request to form a team.

Then, Yang Fan followed Zhi Brain to the place where everyone gathered, as for what necessities to buy, sorry, Yang Fan is a poor man now, and he can't afford anything.
