I've lived in this building for a while, and it's the first time I've been to the second floor.

The tenants in the building, the laundry is dried in the corridor, but there is obviously a staircase leading to the rooftop.

The presence of staircases proves that this old building, like many residences of that period, preferred to reserve half floors. The reserved half-story building is actually a rooftop, where you can have more places to dry things.

Like the older generation, they have an extraordinary pursuit of the drying field, which may be the worry engraved in their bones about the lack of food production in the old days. They always like to store rice, flour, red dates and other foods that can be stored for a long time at home, but because they can't eat them immediately, they must take them out to dry from time to time to prevent insects from growing insects.

Wei Flail felt that the third floor was not so simple, and there must be some secrets in it that Fang Dongfang Deshu sealed it.

He climbed up the stairs, and the first thing he saw was a rusty iron door. It is impossible to pass through with the size of a human being, but it is not a problem for some small animals to come and go freely.

Wei Flails stepped forward and tried to tug at the iron door, but in response to him was the dull, solid sound of the door crashing against the wall. Behind the iron gate was a white gray wall, which made Wei Feng feel that the painting was too much.

The presence of the wall behind the door was already enough to prevent others from going up to the third-floor rooftop, and the existence of this door was purely superfluous - probably no one would smash the wall with a hammer to satisfy their curiosity.

However, the iron door in front of him was not only strong and strong, although there was some rust on it, it could not be opened by brute force. Add to that a large dark blue peeling paint block on the door - the keyhole has been rusted by fuchsia rust, and there is no way to open it.

Without tools, there is no way to go to the third floor by yourself, maybe the iron ladder on the exterior wall will be a breakthrough. However, there is no need to do this. Because of an unreliable conjecture, without safety measures, climb from the first floor to the third floor along the iron ladder that has not been used for many years on the outer wall?

Someone might do that, but this person is not Wei Flai. He still has to meet with the mask man, and he is busy finding out the truth about his father's death, and at this juncture, he doesn't want to have a branch.

Creak!

He heard a stealthy, high-pitched rodent cry that seemed to come from the wall behind the iron door.

It was just a bare white-gray concrete wall, and Wei Flails plucked out his ears.

He had slapped the wall with his hand, and the pain of the hand was always dull. It's strange that there is a rat-like cry coming from such a solid wall.

He raised his feet and turned to leave, but once again heard the cries of the abominable creatures. They whispered like an evil sect with bad intentions, and the unformed conspiracy was as unappetizing as the slime from the sand of 10,000 slugs in their lifetime.

Wei Flail couldn't ignore the unusual sound, so he turned his head again.

He knew that curiosity killed cats, but he inherited his father's aptitude for adventure.

It's midday and the daylight is almost at its fullest. Whatever the information, there is a common point in mind. Dark creatures such as ghosts are afraid of sunlight and can effectively traumatize dark creatures.

Therefore, his heart settled down a little, and even if there was anything dirty at noon, his personal safety should be guaranteed.

The closer you get to the iron door, the more unstoppable the secret and disgusting croaking of rats becomes. Only then did he realize that sound could also bring such indescribable disgust and annoyance to people, and he thought of the corpse of the rat that had disappeared a few nights ago.

He saw a black hole in the bottom of the white plaster wall, so he crouched down. This position was not so easy to maintain, he felt extremely difficult, and even though he stretched his neck, he could not see the inner layer of the black hole. Every staircase had a drop, and Wei Flails took a few steps back, and only bent his legs slightly to see the black hole.

Red eyes!

Wei Flails involuntarily leaned back, but fortunately he hadn't forgotten that he was standing on the stairs. Before falling, he reached out and grabbed the handrail of the stairs next to him.

He felt a little dry in his mouth and sweaty palms.

This red eye gave him an ominous feeling, and he used to only smile and not take this feeling too seriously. But now, after a series of events, his firm materialist outlook has become less materialistic.

What could be the eyes in this red light? Will it be a threat to itself?

Wei Flail had to take a cautious and cautious attitude, staring at the red eyes in the black hole. Perhaps it was because he felt Wei Fang's staring at him with his bare and naked gaze, and those red eyes did not retreat but advanced, and they actually crawled out of the black hole.

Gray and unpretentious short hair, pointed heads, small mung bean eyes, long beards, funny short quadrupeds, and long tails are undoubtedly consistent with the description of the rat in the four pests.

I don't know how many times I have endured the baptism of this false alarm, but there have been too many such shocks lately. He felt as if he had developed a certain degree of resistance, but to his displeasure, he seemed to be much less courageous.

At noon, I was once again frightened by these flat-haired animals.

After the mouse got out of the hole, it shook its nose and raised its front body slightly to look at Wei Flai. One person and one mouse looked at each other like that, and the unspeakable pressure permeated Wei Fang's heart.

It shouldn't be, it shouldn't be......

He looked at the mouse again, unable to understand why he was stressed.

The mouse's eyes seemed to be full of care, and he looked curiously at the strange intruder. The word cowardly as a mouse was a little inappropriate to put on it, and Wei Flail felt that he must be crazy!

In the eyes of this mouse, he saw banter, curiosity, and disdain, how could so many emotions appear in a little mouse?

He decisively took off the soles of his shoes, just as he had done the other night, holding his slippers in his hand and aiming at the hole. The slippers came out of his hand, and with the hardness of the slippers he was wearing, they flew out at this speed, and the effect of smashing into a person was tantamount to a brick halved. He calculated the rat's reaction to being frightened, and in the panic it would be hungry and subconsciously wanted to turn around and go back into the black hole's nest.

However, what happened in the next second surprised Wei Flai, the mouse did not run around, and the wonderful scene he expected of the slippers hitting the mouse and causing the mouse to vomit blood did not happen. The mouse only took a few lazy steps forward, its black slippers bouncing feebly a few times, and then, intriguingly, glanced at Wei Flail with its red eyes before burrowing into the hole.

Wei Fang's heartbeat increased a little, and he actually saw that he was about to face big trouble in the eyes of this mouse.

Hehe, although this flat-haired animal is a bit of a Taoist, it is not like an ordinary animal, it seems that there has been an unknown mutation. But as long as they belong to the category of rats, then the person who is the primate of all things has a way to deal with them.

In the process of fighting the four pests, human beings have invented many tools to effectively kill rats by virtue of their ingenuity.

Wei Flail didn't want to waste money on these raticidal tools, he had his own way.

He had observed the old building, which had no hanging ceilings. The rat's short claws, as well as its hard teeth, have little effect on the concrete building. At the moment, the rat hole was supposed to be their only exit, so he took local materials, ran upstairs and downstairs, and found some discarded strips of cloth and rubble of various sizes.

Gravel blocks are stuffed into the holes and then filled with strips of cloth. Wei Flails felt that one layer was not safe, and another layer was blocked in the same way.

Cave 1 was like water in a boiling oil pot, and the shrill and shrill rat cries creaked and creaked as if the pot had exploded.

Wei Fang felt a little furious in his heart, and his action of blocking the entrance of the cave seemed to provoke the masters in the cave.

He couldn't imagine what a huge swarm of rats lived in the space inside, as if he had poked a hornet's nest, and the miserable and angry cries of the rats made his ears buzz incessantly. If it wasn't for his own experience, he couldn't imagine that there were so many rats hidden in a small mouse hole.

The landlord said that the tenant did not pay attention to hygiene, but in fact, she did not pay attention to hygiene, right? The rooftop hut had such a large colony of rats, and she didn't do anything to let them live here for so long?

With such a huge number of rats, I am afraid that the eighteenth generation of rats are in it, and they are like families in human society, who have lived together for generations, with the reproductive ability of mice, such a thing is not impossible.

But if any living thing wants to live, it must consume enough energy. Based on the sound of rats alone, he estimated that there were no less than a hundred rats on that side of the wall.

Where does their food come from?

People from the old city come and go, and there may be some people like them who are forced to live in this place. Also, there are some people who are still in this old town and are reluctant to give up their property in their home.

But how many of them will there be?

Can you feed a colony of less than 100 rats?

He had already walked around the seven or eight hundred meters radius centered on the old building, and it was all a depressed scene. These old buildings have become veritable "ghost buildings". Basically, you can't see the footprints of people's activities, and outside of this, Wei Feng hasn't had time to see it. However, these rats could not travel several kilometers overnight to the new town where food was relatively abundant, and then, after they had eaten and drunk, they brought the food to the enclosed hut on the third floor of the roof of the old building where he lived.

Wei Flail was already certain that there was a sizable space behind that wall, which could accommodate a huge colony of rats of no less than a hundred rats.

But rats that have never heard of anywhere will unite like marching ants and gather in one place in large areas like humans.

No less than a hundred mice?

Wei Flai's legs and feet were a little weak when he thought of this scene, and at the same time he felt a trace of cruelty. He may have blocked their only way out, and the large swarm of rats that lived inside might not last more than a few days before they ran out of food and died. The dead corpses of their companions may become food for their mouths, and then go through this process repeatedly, completely eating together during the Great Mouse Famine.
