I quickly searched for the surrounding buildings. Almost all the buildings here are hemispherical bunkers, and almost every one has traces of human habitation.

There is no so-called road, it is completely a city designed for war. It either jumps directly on the bunker or transfers its position through underground tunnels. The ground in each building has a metal door of the same size, which is a bit like a tunnel warfare.

As for the origin of this Fortress outside the West, Liu Xiao also found the answer from some relics.

Hei Shui City is its former name.

A man named Leles recorded his experiences here in his notes. This man came from a human tribe named Qab, and he didn't know what he was doing. He was detained by the tribe and was ready to be punished. The tribe's patriarch gave him a choice, either to be a local thing called Liusha Beast as snacks, or to sell his life to a force, and never come back from now on.

Do you still need to choose this? Anyone with a little brain will definitely choose the latter. Let’s talk about whether they can come back or not, at least save their lives first.

So, Leles was taken by two strange and powerful people like a courier, and traveled to several city-states and finally came here.

At first, because he didn't know where the city was, he thought it was a place where a large number of murderers gathered. He wanted to please high-ranking spiritual power by fighting each other, and he might also need to perform some extremely dangerous entrusted tasks in exchange for the qualification to survive, or to be stationed in the margins of human race and other races.

As a result, he guarded an isolated city at the junction of the fan ring and the evil deeds. This was told by others.

Life here is relatively free. No one will restrict everyone except having their own bunker. Even if you leave Hei Shui City, it doesn’t matter, as long as you can go back alive.

After coming here for a long time, life was boring.

Except for occasionally going to stand on the city wall, Leles basically spends money on food and drink here. You can eat and drink whatever you want, but you can't ask for a good taste.

There are many people who have similar experiences to him, and from their mouths, Leles gradually got to know this place.

Rather than saying that this is a fortress, this area is called the Lingyu Land, and almost all around are controlled by the beast tribes. Only a few human tribes have taken root in the Anxi Grassland, but it is too far away from here to reach it safely. The enemy guarding against Hei Shui City is a ferocious beast. It's strange that there are not many ferocious beasts nearby, so there is no need to gather so many combat power, let alone build such a large defense system, otherwise those tribes would have been exterminated long ago.

But from time to time, ferocious beasts will invade this place on a large scale.

Leles mentioned a question in his notes, which was also a question that Liu Xiao was more puzzled.

Why do they have to keep here?

But this answer was not mentioned until the end of the notes. Leles had only guessed that there should be any ulterior motive secrets underground in Blackwater City. The only free door was underground, and he was also brought from the ground while isolating all senses.

hidden.......

These four words are very attractive.

As time goes by, perhaps this hidden secret has disappeared with the fall of this fortress, but there will always be some clues left.

Moreover, judging from the information we have already obtained, the time when Hei Shui City existed should be before the tribe of the Shelter City moved into the Bone Burial Sand, and perhaps we could still understand what happened at that time.

The existence of evil spirits is not mentioned in the notes, that is, the Hei Shui City and the Lingyun Land at that time did not actually have these strange auras that scattered the world. How could it be there after that?

Could it be that there are too many people who die here and are too resentful? It's not that.

Leles' notes, coupled with the information obtained by Liu Xiao's observations, can roughly restore some of the situation at that time.

An unknown force built a fortress in Lingyun Land. Instead of adopting the traditional city-state order, he encircled death row prisoners with certain combat power in the fan ring to survive and die with the fortress. If they die, they will replenish them.

The key question should be what this force is doing here, why the ferocious beasts travel thousands of miles to kill, and how did the fortress fall in the end?

Another point that Liu Xiao cares about the most is the free door mentioned by Leles.

When he fell back to Wangcai's back neck, he found that this stupid big man who was a little idle and panicked was actually picking his nose!

Can you imagine? How big and disgusting the booster it is when it is more than 200 meters tall? Also, its booster is almost exactly the same as that of a human. The booster explodes in the ruins like a cannonball.

Only then did Liu Xiao realize that Wangcai was so familiar with the claws that were dozens of meters long. The whole movement was done in one go without any delay.

"Let's go, let's go to the city center to take a look, don't have to be too fast."

"Okay, master." Wangcai replied in a naive manner, and walked forward with big strides.

"Can you not call me the master in the future? It sounds very disgusting." Liu Xiao said to his big pet while scanning the surrounding ruins.

"What does sensation mean?"

"It's just uncomfortable. Every time you call me master, I feel very uncomfortable."

"Then what should I call you? My name is Wangcai, then, or I call my master Wangwang?"

"...... Forget it, you'd better call me the master."

.........

As a fortress, the scope of Hei Shui City is a bit over the top.

The scope is at least equivalent to a third-tier city in China. It also shows that the number of humans stationed here at that time was astonishing. These people were all of them with certain combat power. Although Leles' notes did not mention it, Liu Xiao guessed that he was at least a high-level traveler.

The ground is full of big butt crawlers, and these insects and beasts are almost not aggressive, but they have a relatively large visual impact.

Wangcai was too lazy to destroy them, and stepped on them on his own. Every time he landed, dozens of reptiles were tragically poured into soup.

Liu Xiao was not very interested in these insects. He was just a ferocious beast that occupied the magpie's nest after the fortress fell. As for the ferocious beasts but did not attack the invaders, it should be driven by the instinct of these insects. They were not all still, and some of them would crawl in the same direction, and this direction seemed to be the center of Hei Shui City.

Wangcai accelerated his speed, changed from strides forward to running quickly, and the entire surface was trembling violently with its pace.

Not long after, Liu Xiao saw a unique building.

At the same time, the hemispherical shape of the bunker is different, but its difference is that it is large! It covers an area of ​​two thousand meters in diameter, and there are a large number of entrances at the bottom, and those moving crawlers are drilling in through these entrances.

There was a loud bang.

The solid exterior wall was exploded by Wangcai's claws.

The giant beast and Liu Xiao on its body looked inside curiously.
