My main world is in Naruto

The underground city remained underground for less than a hundred years.Nearly 200 years of consumption have already exhausted all supplies.The upper classes eat chicken.The average person eats maggots.The lower class people also find some moss to survive.Population pressure led to social instability, and eventually underground war broke out.

But the war comes and goes quickly, because there are always people who are sneaking around because of the war.Cannibals are discovered.Human beings aimed their guns and brought the cannibals to justice first.Finally everyone came to the negotiating table to discuss.The end result is too much underground population.We need to carry out family planning to control overpopulation.The first existential crisis passed like this.

I thought that this way the dungeon could maintain peace for a while, but it might be revenge.Or perhaps it was fate that a cannibal used a car to knock open the base's insulation door.The door that had not been opened for a long time was opened.The temperature was like a raging fire scorching the first three underground floors.Objects burn instantly.Some vehicles also exploded quickly.The leader quickly closed the passages above the fifth floor.Open the cold storage to cool down the dungeon.Finally, the upper five floors were completely scrapped, and a breeding base was scrapped.But everyone still decided to let the death squads block the new door.

Several people wore fireproof suits and climbed to the elevator shaft on the first floor. Only a piece of scrap metal was left in the burning car. The insulation door was closed in front of them, but a large hole had already deformed the insulation door.The department staff asked several people to block all the passages, which could isolate some heat waves and prevent madmen from opening the door a second time.

The captain mixed some metal with dust from the ground to seal the door. These metals will become liquid at high temperatures and will slowly solidify after being mixed with dust. After the final crack, the sky outside is colorful and the earth is red.This is the last time the underground people take a look at the world above.

The underground city lord ordered.Nowadays, the surface temperature is gradually increasing.Plus damage to the insulation door.The dungeon must go further down.Ordinary people must work in exchange for food.

Unknowingly, a new social form unfolded a hundred years later.Take the city lord and the knight.noble.The classes into which miners were divided solidified.There are only two paths for those who break the law, up or down.It’s too hot to go up, but it’s exhausting to work as a miner going down.

Over the centuries, food has become more abundant.Small fish, crabs and some hot water plants that can survive in the hot springs became the favorites of the nobles.The miners will use some minerals, moss, insect corpses, and cakes made from the food scraps of the nobles as their food.

The End of Dungeon was recorded very sloppily.It seems that there was a miner named Apollyon who wanted to make a fortune raising his own fish.At least I can have a meal.He knew that the hot water was coming from the hot water pipe on the third to last floor.

Apollyon followed the pipe in search of water.But what he didn't know was that there was an electrical system in the underground city. This system could not only use an electric drill to drill through the rock wall, use a robotic arm to install pipes, and a computer to control the water flow.Even electric drainage systems and waterproof isolation hatches ensure the dungeon is foolproof.But this knowledge has become a knowledge gap among miners.He led a few people to dig secretly, and after digging desperately, they finally dug out a water channel that was not recorded on the computer.

He might have laughed out loud when he opened a channel for underground water outside Apollyon, but he probably understood it within a few seconds.Boiling water falls from the sky from the bottom three floors.The people on the second to last floor were drenched with boiling water before they could react.The computer host completely blocks all channels.But only the newly built underground projects were preserved.The nobles and knights died in the boiling water.Only the miners survived.

The water slowly rose, and a large amount of air pressure opened a hole in the underground city through the elevator shaft.The insulated door on the first floor was also blown open a second time by the air pressure.Finally, the water rose to the fifth level from the bottom and finally balanced with the groundwater next to it.

But that's not all.
