In a mountain range in City X, two petite figures are hurrying on their way.

"Whew... Oh! ”

Suddenly a beast's roar came from the jungle on both sides of the road.

The two brothers hurriedly quickened their pace and trotted all the way.

"Brother, look, it's not far away, and it will be safer to rush to the big army."

The other teenager nodded.

"Let's go, get over early."

"Okay."

The two of them quickened their pace again, hurrying towards the crowd in the distance.

As soon as the two of them couldn't leave, the ground in the station just now suddenly broke open, revealing a cave. A pair of large pincers protruded from the dirt.

Gradually, a giant ant crawled out of the burrow.

The sound of "sizzling" behind the ants was endless, and after a while, giant ants emerged from the darkness.

In 2160 AD, due to the overexploitation of the countries. The earth has become devastated.

Due to the thinning of the ozone layer. Global warming has led to frequent disasters.

However, at this time, human beings were still fighting for their own interests without restraint and overexploiting the earth.

As the resources available for exploitation and collection have dwindled, some large countries have put their claws into the pockets of weaker countries, causing turmoil in the world. War broke out.

From the beginning of the local war, to the later world war.

After hundreds of years of human development, colleagues in science and technology have progressed, and weapons are constantly being updated. At this time, nuclear weapons were already widespread in all countries.

The superpower has developed a new form of weapon, the "supernuclear weapon." Because the weapon is too harmful, it has been listed as a prohibited item.

And nuclear weapons, as the main means of warfare at this time, after several years of great war. From space, the ground has changed from azure to dark gray.

After the Great War, mankind finally realized the dangers of war. Thus the "Armistice Treaty" was signed. ”

Year 2170.

As one of the world's several superpowers, due to the influence of the mutant beast, the decision-makers of country Z made a decision to go underground for the surviving population. And the plan was named "Woju". It is preparing to relocate all of the country's remaining 2.5 billion people underground.

In the middle of country Z, at the foot of a large mountain. There's an entrance to the underworld.

A 90-meter-high and 200-meter-wide arched gate is built against the mountain. Robots stand on either side of the gate. A total of twenty-five dungeons like this were built in country Z, and one city contained 100 million people. After it was built, it opened up the cities underground. Thus a real underground state was formed.

After a year of working with the help of artificial intelligence robots, the underground site has begun to take shape. Countries around the world have also begun to migrate people to the underworld.

At the entrance to the dungeon at the foot of the mountain, there was a long queue at the moment, and it was slowly marching. There are hundreds of thousands of people in the distance, but that's less than one percent of the city's entrants.

There are robot guards every fifty meters on both sides, protecting the safety of these civilians at the moment.

The large mutant beasts in the forest have been wiped out before the dungeon is built, and those that cannot be destroyed have been lured deeper into the mountains.

But with the gathering of hundreds of thousands of people, the taste can't escape the senses of some mutant beasts. From time to time, some mutated ants, centipedes will break through the ground, waving large pincers and rushing towards the crowd. This is where these guard robots come in handy. They are the most advanced systems of our time, with intelligence comparable to that of humans, and when they lock onto their targets, they launch pocket missiles in their bodies. The mutants had been killed by the guards before they could even burst into the crowd.

The two brothers, Li Jun and Li Lin, came together after receiving the notice. The two brothers are now dependent on each other, and their parents were former military officers, but they died honorably in the war. I was raised by my grandmother at home, and when I came, the two brothers tried their best to pull my grandmother together. But after the grandmother said a few words to them, she pushed the two out.

"Grandma is old and reluctant to leave this house. I don't want to move anymore. You two are still young, just go. ”

The two knew that their grandmother had made up their minds not to leave, so they knelt down in front of the door and kowtowed three times to their grandmother.

"Grandma, don't worry, I will take care of my brother, we will definitely not embarrass the Li family, I will definitely live a good life."

After the two of them finished speaking, they left.

The center of the long queue.

Li Jun looked at it at this moment, and the long queue in front of him was still moving forward little by little.

As far as the eye can see, the once green forest has now become bare, and after being burned by the fire, only the trunks of the trees are deeply embedded in the ground, and the ground is covered with a layer of ashes from the burning of grass and trees. The wind blew, leaving only the trunks of the trees to sway, and the rustling of the leaves could no longer be heard. Bursts of terrifying biting and roaring came out of the woods.

After the war stopped, the earth was still dark gray from the air, and the air was full of dark gray particles and various diseases caused by nuclear radiation, and the total population of the world was sharply reduced by one billion. In the past, various animals in the jungle also had various mutations due to the hazards of nuclear radiation. Small insects that used to be inconspicuous in the eyes of humans can now threaten human life, ants as big as calves, and large steel pincers in their mouths. Wasps as big as eagles with spurting stingers, locusts, centipedes, and so on ..........

"I don't know if I can go in today, I don't want to spend the night outside."

Behind him, his younger brother Li Lin looked up.

"Brother, don't complain, save some strength to hurry, look at this situation, we can't get in tonight. This man has tens of thousands, to say the least. ”

Li Jun shook his head, "Alas, born in this troubled world, what kind of life is this?"

Everyone around me had a blank face. They were all hurrying away, but the two brothers could still say a few words.

After a few more words, the two brothers also walked up.

After walking for twenty miles, it slowly became dark.

In the dark, people have an inexplicable fear, and in order to serve this fear, someone in the team gradually talks to the people who are hurrying next to them, and this fear will be reduced a lot as soon as they speak. After a while, the conversation began to increase in the ranks.

Li Jun suddenly heard a girl's subtle crying, and the cry gradually became louder.

Li Jun heard the crying not far away, so he walked over with Li Lin and saw a girl of the same age as them squatting on the ground crying.

His long hair had been stuck together with sludge, and his thin face was covered with dirt, looking like a little beggar.

Li Lin didn't want to be troubled, so he pulled Li Jun and wanted to leave, "Brother, don't be too troublesome, let's go." ”

"I don't know what's wrong with her, let's go, since I've met it, I'll go over and ask. Anyway, I can't get in today, and I don't care about this time. After Li Jun finished speaking, he walked over.

The two walked to the girl's side, Li Lin didn't want to care, he just stood aside and watched.

Li Jun squatted down and asked, "What's wrong with you?" Are you in any danger? ”

"Woo, woo" The girl kept crying and did not answer Li Jun's question.

Li Jun looked at it and saw that there was no way, so he scared out loud, "Don't cry anymore, if you cry again, the mutant beasts around here will find the voice." Then everyone will be in danger. ”

Sure enough, everyone has a fear in their hearts about mutant beasts. After hearing Li Jun say this, the girl stopped crying.

Seeing that the girl was no longer crying, Li Jun took out a piece of paper from his pocket and handed it over, "Okay, now tell me what's wrong with you? Why is a person crying here? ”

"I'm scared, it's just me, I'm scared ......." The girl opened her big watery eyes and looked at Li Jun, and said with some grievances.

"Scared? With so many people, what are you afraid of? ”

"I was afraid that it would be dark, and it was during this time that my parents were bitten to death by a mutant beast. My parents hid me at the time. I saw with my own eyes that the big bug bit my parents to death with a pair of big pincers. Every time I came from then on, I was terrified. Woo, woo. The girl cried as she spoke, and the more she cried, the harder she cried.

Li Jun doesn't know what to do, and he won't persuade him. looked at Li Lin.

Li Lin urged, "Brother, let's go, we have fallen behind for a while." Don't worry about it, you can't even take care of it. ”

Li Jun couldn't bear to leave this girl, since he had met it, he would help if he could.

"And who are you coming with this time?"

"Woo...... I was brought here by a neighbor, and they left after I came, and now I'm alone." After saying that, the girl wiped her tears.

"Okay, then you can come with us, this is my brother Li Lin, my name is Li Jun." Li Jun saw that there was no way, so he wanted to take her with him first, and then talk about other things after entering the city. and introduced the girl to his brothers,

The girl stared at Li Jun and Li Lin for a while. Nodding, she couldn't help it, so she was alone. Without a companion in such an environment, people would go crazy.

The girl stood up, wiped her tears, and followed the two, and the three of them got up and hurried away.

After walking for a while, the girl's stomach growled.

Li Jun glanced at it. The girl lowered her head. I couldn't see any expression on the dirty face.

He took out a dry ration and handed it over.

"Here, eat, eat when you're full, and then you're ready to go."

The girl stole a glance at Li Jun before reaching out her hand to finish the food.

After eating, she followed after a few steps.

"That's... Brother Li Jun. I'm sorry, I just came here and ate a piece of your food. I was so hungry that I hadn't eaten in a day. Also, my name is Sun Qian. ”

Li Jun smiled, "It's okay, our brothers are also fatherless and motherless, and many friends will take care of them in the future." ”

Sun Qian smiled, "Well, hee-hee." ”

Li Lin didn't say a word, just cared about hurrying away. He looked back at Sun Qian, revealing a look of disgust.

It's just that Li Jun and Sun Qian were talking, and they didn't see it.

After walking all night, the three of them rested for a while and continued on their way.

Finally, at six o'clock in the afternoon, we arrived at the entrance gate.
