About 117 years ago, the first meteorites were observed heading towards the Earth. At that time, in order to solve this matter, everyone talked about it; Everyone knew that this was inevitable, and many plans were proposed.

Someone proposed to blow up a meteorite with a nuclear bomb, only to find that all the nuclear bombs in the world together were not enough; So there are only two options left, one is to find the underwater city left over from the last human civilization, probably near the Ahuna Trench; The second is to establish underground cities in all the northern hemispheres far from the meteorite landing point in 17 years.

Meteorite impacts bring not only tsunamis and storms, but also ecological imbalances. The sun was covered by smoke and dust, and the northern hemisphere was better, while the southern hemisphere was completely wasteland.

Due to the lack of time, the underground shelters built were only enough to accommodate less than two billion people, and the rest had to build strong barriers above the ground and survive on the wasteland.

Later, the humans on the surface survived, and over the years became increasingly hostile to the inhabitants of the underground vaults.

The Watchmen, the most powerful organization of terrestrial civilizations.

The Underground Secret Service, the most terrifying department of the underground civilization.

Shelters need resources, cities on the ground need technology, and skirmishes break out from time to time.

Some people have raised the question of why they are all human beings, but they have rifts that are difficult to heal.

That's because the humans in the ground ramparts think that they are an outcast in the midst of a disaster. To this day, they are still battling the aberrant species brought about by the cataclysm, and the humans in the shelter are free of food and clothing.

Aberrant species are species that theoretically cannot exist in the world. Because even if the ecology is unbalanced, it will take at least tens of millions of years for complete species variation to appear. However, the aberrant species have appeared in just a few years, and some of the remnants of the earth's animals can be found in their genes, and there are also incomprehensible parts.

Most researchers believe that this is caused by some special substances in the meteorite.

So far, no research has been done.

**********************************************************************************************************************

One hundred and seventeen years later, East China No. 3 Barrier, the Warden Division.

"Lao Cao, what's wrong with the black box, I'm panicking."

It was the person in charge of the No. 3 barrier, the bearded Ma Yunde.

"You come here, you come here." The fat man, known as Lao Cao, grabbed Ma Yunde by the sleeve and dragged him into a brick house, outside which was covered with yellow sand and dry weeds, and the surroundings were desolate.

Lao Cao found a folding stool in the corner of the house and sat down, and the stool let out a melodious mournful sound. He turned on the computer in front of him, but as soon as he turned it on, a burst of high-pitched soprano sounded, Ma Yunde couldn't really hear it, only vaguely heard that it seemed to be mixed with some foreign languages such as "Yamei Butterfly" and "Qimo Chicken".

At that moment, Ma Yunde only felt that this was really ...... It's so admirable! Although Lao Cao gave priority to work and quickly turned off the player, he still didn't expect Lao Cao to be so studious, and he still had the ambition to learn a new foreign language in middle age, which was really a model of living to learn from all the time!

Thinking of this, the person in charge of the barrier patted Lao Cao's shoulder and smiled meaningfully-Lao Cao, I'm optimistic about you!

Lao Cao: ???

Lao Cao subconsciously covered the mouth of the dish, struggled in his heart for a moment, and finally sighed faintly. Forget the old horse, for the sake of many years of classmates, I will send the saucer to your room at night......

Ma Yunde saw Lao Cao's more and more resolute expression, and became more and more satisfied, this is really inspiring!

Turning his attention away from the foreign language textbook, Lao Cao opened the folder and found a video file in a pile of orange and black signs, and clicked on it after confirming it again and again.

This is a surveillance video, when Ma Yunde saw the black box in the middle, he raised his eyebrows, "Yo, Lao Cao is good, the chess pieces are all installed in the general control room." ”

"Then you have to, don't look at what kind of person I am Cao Tahua." Lao Cao showed a smug expression, "I still took a lot of effort to find this." ”

Lao Cao pressed the play button, and the picture began to change. The video shows a huge warehouse with a bunch of guards guarding nearby. Originally, the picture was quite normal, until suddenly a water pipe in the ceiling was opened, and water under high pressure sprayed out, which immediately rushed the guards to the ground.

After another two seconds, a figure suddenly appeared and landed behind the box.

Lao Cao enlarged the picture and pointed to it: "Old Ma, this is the person you sent, the thief is good, this tiger claw is used, tsk, skilled!" ”

Ma Yunde was stunned for a moment, then looked at the Winnie the Pooh short-sleeved covered on the man's face, and said with a dark face: "I'm sure it's not my person." ”

Lao Cao snorted and turned off the computer.

"It's weird, it's not your person, is it the inner ghost in No. 77?" Lao Cao pushed open the door and walked out of the house, lost in thought, although Ma Yunde didn't think it was useful......

After a while, Lao Cao began to pace around the room. After pacing for more than ten minutes, Ma Yunde suddenly spoke: "Lao Cao." ”

"What's wrong? You know that person? I'll just say, old horse, you have great powers, what can't be solved......"

"No, I'm dizzy when you turn around......"

Lao Cao stopped suddenly, "Then what to do now, the box was taken away, this Wang Haicang is really, he can't even look at a box, in my opinion, next time they will directly open an armored company and push the shelter." ”

Ma Yunde thought for a moment, "Don't be stupid. Now the priority is to find this man with the black box. Old Cao, you move all your movable chess pieces, why don't we find him in front of the gray rats of the Secret Service. ”

At this time, a soldier trotted towards the brick house, snapped to the ground and saluted, and said, "General Cao, the direction of Xishan is tight, and our No. 3, No. 5, and No. 11 barriers are blocking the path of the distortion migration. Director Li hopes that you can transfer another garrison to him, otherwise there will be a fault in the joint defense line with Barrier 11. ”

Cao Tahua breathed a sigh of relief, and finally didn't have to think about the person who stole the black box anymore. Otherwise, every time I think of it, I think of the mask of Winnie the Pooh, and I always feel weird......

So he frowned and looked at Ma Yunde, "Old Ma, has there been a change of person in charge on the eleventh?" ”

"Yes. Yang Wuliu, that old guy recuperated from his injuries. The newcomer seems to be quite young, called Yang Sijiu. ”

"No matter how many times I've heard them, I think the names of those guys are weird." Old Cao muttered.

"Then you tell Director Li and tell the commander of the 11th unit to wait for two days, because it will take some time to assemble the troops." Ma Yunde thought for a while, "Then ask Lao Li to send a letter to Chen Jing of the No. 5 Barrier, asking him to send a reinforcement company to Ma Lao Mountain on the Western Front to keep an eye on the joint defense line." If something happens, do him a favor, find the black box and divide him in half. ”

The soldier saluted and trotted away.

"Lao Ma, are you relieved that Lao Li can't be relieved?"

"No, I'm worried about Barrier Five." Ma Yunde said in a deep voice, "In any era, human beings are the greatest threat. I wouldn't be surprised at all if Lao Li's battalion was eaten. The East China headquarters has existed in name only, so it's better to be careful. ”
