Instead of wandering around the area where the third-level citizens are located, Xu Yi left the Dark City and returned to Shaonan Base.

When Xu Yi came out, Ling Yue and the others had completely controlled the military base.

"Xu Yi, how about it, is that dark city interesting?" Lu Ran saw Xu Yi coming out of the portal and jumped to Xu Yi, staring at Xu Yi with curiosity.

Originally, all the people in the base were controlled by Ling Yue and could only come out after passing the psychological test.

So at this stage, except Xu Yi, other people who know the Dark City, Lu Ran and others cannot get in touch with it.

Naturally, Lu Ran came to ask Xu Yi.

"I didn't find interesting places, but there are many stalls and all kinds of strange things. They come from different worlds." Xu Yi said truthfully. After all, he didn't have much time to find interesting places.

However, he could understand Lu Ran's mentality.

After all, the City of Darkness is a special place, and it is very new and novel to them.

Naturally, I just want to play and relax.

"That's very interesting. Shopping is the most interesting thing. Unfortunately, I heard from Sister Yue that it takes three days to go there for free, and it only takes four hours to go shopping."

"Now, we have no streets to visit except for the large supermarket in the logistics department. Xu Yi, can we go shopping now? What should we pay attention to when we go to the Dark City?" Ning Ya looked impatient, as if she hoped to go to the Dark City to go shopping immediately.

"I will sort out the things that need to be paid attention to. You can go in an hour." Xu Yi also has this purpose when he came back this time, because it is not enough to go to the Dark City alone. It is best to let others go to the Dark City to experience it.

Of course, it is best to let them go to the fighting arena and feel the feeling of a life-and-death battle.

For challenges at the same level, unless the luck is particularly bad, the difference in strength should not be particularly large.

There is no need to challenge it often, at least one or two challenges are necessary.

However, Xu Yi had to prepare some things for them to save their lives.

Xu Yike had no way to rescue him in the fight field, and he could only rely on themselves and what they carried.

Xu Yi consulted that the fighter can carry some things to save his life, but there are limited quantities, no more than three at most.

After hearing that it was enough to go in an hour, the senior executives of the Qikill Army became happy.

Not only Lu Ran and Ning Ya, but others also want to see the Dark City, and also want to see the stalls set up by other civilizations.

It doesn’t matter if you can’t afford it, it’s always OK to stroll around.

In addition, with Xu Yi here, they knew that he would definitely find the fastest way to get points.

They have this confidence in Xu Yi.

So Xu Yi went to organize the materials, and they went back to change their clothes and prepared to go shopping.

In less than an hour, Xu Yi prepared the information.

All these materials were sorted into text and handed over to the senior management of the Qikill Army.

Currently, they are the ones that are suitable to enter the Dark City.

When they are familiar with the Dark City, they can then let ordinary warriors enter the Dark City.

At the same time, copy some patterns of the Dark City.

If others are excellent, they naturally need to study hard.

It is not embarrassing to learn from others.

If you hold on to it and don’t learn, you may lose everything. Face is really not important, especially in the face of survival, which is even more valuable.

Half an hour after obtaining the information, the senior executives of the Seven Killing Army entered the Dark City one after another and registered as first-class citizens of the Dark City.

Xu Yi did not follow him, even Ling Yue went to the Dark City.

Because Xu Yi wants to upgrade the EMU system to increase its speed again, so that he can quickly travel between Shaonan base and Steel City.

Although the subway between the two places has not been repaired yet, there are supernatural warriors who control soil and rocks, and it doesn't take too long to open the subway.

Next, Xu Yi may stay in the Dark City for a while to improve his strength, so Xu Yi wants to deal with the things he can handle first.

Xu Yi found the subway and then directly upgraded the subway.

This time, Xu Yi spent 50,000 to survive.

Although there is only one upgraded EMU, it can transport 1,000 people at a time. With such transportation volume and its super fast speed, the transportation capacity is still very strong.

Therefore, an upgraded EMU can already meet the basic needs of the Qikill Army.

In addition, it can also be used with other EMUs.

After upgrading the EMU, Xu Yi went to meet the people from the scientific research center.

Laser weapons are still not enough, Xu Yi wants to upgrade his production tools.

He hopes that the Seven Killing Army can equip some laser weapons. This time, when dealing with the Zerg, the laser weapons still play some role.

However, because the number of laser weapons is too small, the effect is not particularly obvious.

As long as the number increases, laser weapons can form strong defense capabilities.

Nowadays, only eight laser arms can be produced a day, so Xu Yi felt that this speed was too slow.

So, he used 60,000 points to increase the output to 20 laser arms a day.

The daily output can be increased to 20 units, which has exceeded Xu Yi's expectations.

This laser weapon itself has no loss. What needs to be consumed is the brain beads that serve as the source of energy or the energy crystal condensed by Xu Yi.

At present, Xu Yi mainly uses energy crystals condensed by himself.

After all, he is not willing to use brain beads.

Even though all members of the Seven Killing Army have become supernatural warriors, they have also reserved some brain beads for spare use.

However, he still couldn't bear to use brain beads as energy for laser arms.

The energy crystal is different. It can condense and eat the flesh of the mutant beast.

Now, his condensation speed is faster than before.

An energy crystal can be used for more than an hour in laser weapons, and it is barely enough to use it for defense.

After getting through these things, Xu Yi went to the place where the dragon flame and jujube grew.

He wanted to know how many points this fruit could be exchanged for in the Dark City.

He is sure that if this dragon flame vermilion fruit appears, someone will definitely buy it.

However, it is unknown how many points you will use to purchase it.

Xu Yi not only wants to get points by hunting mutant beasts, but also wants to get points through commercial means.

It is not enough to set up a stall alone, even if all members of the Qisha Army go to set up a stall, it is not enough.

Because their level is too low, there are very limited areas to appear.
