Chapter 293： Underground city

quickly.

They came to the vent.

This is a hole with a diameter of only one meter. Several people are already standing near the entrance of the hole. They are watching the wind here. They were almost scared to pee when they saw Ruba being chased by a strange animal.

As for the scene where Lin Shan beheaded the alien beast, they also saw the whole process. They were shocked and inexplicably shocked. When they saw Ruba brought the people over, they all became nervous and looked at Lin Shan in fear.

Such a powerful person appeared.

Do not know whether it is a blessing or a curse.

"Mountain, this is the entrance of our city. It was originally a big vent. Later, when we saw those monsters moving in this direction, we blocked it. The smell inside was a bit big. Please bear with me later." Ruba introduced eagerly.

Lin Shan nodded.

"It's ok."

Finished.

Ruba took Lin Shan into it.

Fortunately, the space in the cave is much larger, and it can pass through with a slight bend. If the entrance of the cave is so small that it can only crawl, Lin Shan doesn't mind digging for them.

Walked more than twenty meters.

The space in front of me is big again.

It turned into a huge cave with a height of more than ten meters. It seems that this is the whole picture of the vent. The walls are surrounded by white rocks, which causes no ice here, but the air quality here is indeed terrible.

The situation below is even worse.

Lin Shan thought.

"Huhuhu..."

A huge cold wind poured in from outside the cave.

"Hi... How come there is such a strong wind?"

Ruba and the others shivered in the cold wind. They didn't know what was going on, but they felt that the surrounding air was much fresher. Even when they thought that they would go down in a few seconds, Ruba felt a little painful.

Ten seconds later.

Lin Shan finally maintained a clean air zone with a radius of 20 meters.

Looking at the passage leading to the underground obliquely in front of him, Lin Shan stepped forward without anyone leading the way, because there was just one road here. Seeing Lin Shan walking forward, Ruba and the others hurriedly followed, watching the wind still watching the wind.

"wrong."

Followed Lin Shan for hundreds of meters.

Ruba finally felt abnormal.

The bad air that I thought did not appear, but as fresh as the outside. Although the air outside is cold and the inside of the cave is warm, the usual sour smell is completely different.

what happened?

How long has the air in the cave improved after leaving?

How is this possible? It hasn't been opened before, and air convection cannot be formed at all.

Ruba looked around and saw the surprise in the eyes of other people. It seemed that his feeling was not an illusion, but that the air was really clean. It was really strange. At this moment, Ruba saw a subordinate. Secretly pointed to Linshan.

Smart he reacted immediately.

Is it because of Lin Shan?

This conjecture came to Ruba's mind.

Go to the end of the passage.

After a turn.

Lin Shan stopped suddenly.

Looking at the scene in front of me, I was also a little shocked.

The front is a huge underground space. Unlike the countless passage-like cities he imagined like ant dens, the entire underground city is located in a huge underground space.

The densely packed houses are distributed on the ground. With the faint light of Shiraishi, it looks a bit like a ghost town. The darkness is the main color of the whole city. It is estimated that the sun has not been seen for a long time. The faces of Ruba and others are a little bit pale.

The space is hundreds of meters high.

It covers an area of ​​no less than 20 square kilometers and is surrounded by white rocks. His current position is on the middle of a mountain, with a vertical cliff of more than 100 meters in front. There are passages that can only accommodate two people walking side by side. .

Not to mention, this design is really easy to defend and hard to attack.

Outsiders wanting to charge on a large scale, there are no conditions at all. In addition, Linshan has seen many organs on the passage, and some of them are designed quite well. It is simply a nightmare for people in the cold weapon era.

"Mountain, this is our city, called Yawu City." Luba was taken aback when he saw Lin Shan, and introduced.

Lin Shan nodded.

After walking down the passage, Ruba quickly followed.

"Why didn't you go to the ground to build a city in the first place?" Lin Shan asked curiously. Obviously, this city was not built after the invasion of alien animals. It seems to have existed for a long time.

Ruba looked at Lin Shan.

A little nervously said: "The last time we sat in the city, it was built on the ground, but it was snatched away by the lord of another city. We were forced to move here and live until now."

"Snatch it? They want the city, they don't want you... Forget it, I understand." Lin Shan wanted to say looting the city, why not looting the population and letting them go.

But suddenly realized that this is not the earth.

This is a planet that is still struggling with a bite of food.

There are no large crops.

There is no breeding industry.

Not even the bark of grass roots.

Unlike places on the earth, where the population represents farmers and productivity, the population here is actually a burden, and those city owners cannot support too many people.

it's here.

The population of each city has an upper limit to support, and the catch in the fishing pond determines the upper limit. During the ice age, the fishing pond was the only source of food and even he heard a lot of orders from Hu Nan. A creepy story.

"Then how do your substances come from? For example, salt, which is the kind of thing that will become weak and sick if you don't eat it for a long time." Lin Shan asked again.

"This is what we have here, there is in the stone, and the stone is ground into powder." Ruba explained.

Lin Shan listened.

Don't think about it.

Since there is no filtering technology, it must be eaten all the salty soil, just like some places in Africa on the earth still eat soil cakes, a very primitive way of eating salt.

Go down the channel.

Step into the city.

In the gloomy environment, Lin Shan has adapted to the light here, and found that the situation here is quite bad. People lying on the side of the road are still breathing. It is obvious that they are not hungry, but sick.

Everyone looked dead.

Snorted from time to time.

Slowly welcome the arrival of death.

When they saw Lin Shan did not move at all, it made Lin Shan feel as if he had entered a dead city.

A lot of spots can also be seen on some skins, which are obviously caused by skin infections. Lin Shan gently brought in a little air from outside. At that moment, Lin Shan almost vomited.

It was an indescribable sour smell.

Such air quality.

People who don't get sick or die are blamed.

"These are people who are sick. As long as they are sick, they will go to the streets. If they die, they will be shipped out, otherwise they will have more serious infectious diseases." Ruba said desperately.

During this period of time, he saw too many people pass away, and he also personally transported the bodies of many acquaintances, among them his two nine-year-old twin daughters became ice sculptures outside another exit.

Wait until the water season comes.

These corpses will be thrown into the mother sea not far away.

Thought of this.

Ruba couldn't help but jealous.
