Zhong Ping brought back a machine - a mousetrap.

It took him several months of hard work to develop this task assigned by his superiors. The

principle is similar to that of an ultrasonic fish trap. The sound waves emitted by the machine will stimulate the mouse's brain, causing their sympathetic nerves to become excited, entering a hallucination, and their bodies to become sluggish, unable to wake up within two hours. Jiang Ning thought thoughtfully, "Just like cats are attracted to cat mint?" Yes, Zhong Ping's inspiration came from cat mint. The family was in great pain from the infestation of rats, and there were also many survivors outside who were bitten by rats. Although the hospital and the epidemic prevention department were prepared, it was not easy to resume drug production, and only the most conservative treatment could be adopted, so the situation was not optimistic. Zhong Ping meant that the two floors should continue to cooperate and try to eliminate all the rats. Jiang Ning had no objection. Although there was a dog to keep them in check, dogs would also get tired. Not only had he lost weight in the past two days, he was so tired that he snored in his sleep, and even fought three hundred rounds with red-eyed rats in his dreams. The extremely hot weather was undoubtedly a disaster for dogs that could only dissipate heat through their tongues. Drinking too much water would also cause water poisoning. Neither of these was what she wanted to see. So, everyone tested the mousetrap on site. The corridor windows on the 17th floor and the doors and windows of the other two households were opened, and the mousetrap that was plugged in emitted a slight buzzing sound. About ten minutes later, the rat with big eyes climbed up along the sewer. It was seen circling around the mousetrap, making a squeaking sound from its mouth, its movements gradually becoming slower, its red eyes full of intoxication... uh, like it was on drugs. A few minutes later, the mouse fell crookedly. More and more mice climbed up one after another, and there were more than a dozen in less than half an hour. Zhang Chao and others were dumbfounded. This is technology. The cooperation was reached. The 18th floor was responsible for catching and killing mice around the clock, and the Zhong family provided mousetraps. The two families took turns to send the captured mice to the neighborhood committee for registration, and the redeemed canned food was divided in half. The 18th floor was not interested in the canned food, but was worried about the harm caused by mice, so they agreed to improve their living environment. So, the mousetrap was carried to the 18th floor, and the doors and windows of the corridor were opened. Each person takes a day shift, divided into day and night shifts. According to the house number, Huo Yishen was the first in line. He went out every two hours to kill the hallucinogenic red-eyed rats and throw them into a sack. By the next morning, a total of 106 rats were killed. More than 100 pounds, not everyone can lift it. When it was Jiang Ning's turn, she didn't even have to go out, Gouzi took care of the work. There were relatively fewer rats during the day, and more than 70 were caught. Huo Yishen went downstairs carrying the assault boat on his back, while Jiang Ning carried a sack of rats. Wearing a constant temperature suit as a base, a medical-grade protective suit on the outside, and a mask on his face, he drove the assault boat to the neighborhood committee to hand over the rats. There is still a lot of floating garbage in the water, but after vigorous publicity and rectification by relevant departments, the environment is much better than in the previous life, and there is no news of the epidemic for the time being. You know, it had already broken out at this time in the previous life. Many people came to the neighborhood committee to hand in rats, but others only handed in a few, and a dozen were already very serious. When they learned that it was from Unit 1 of Jinrong Community, the staff was shocked, "Are your rats rampant? A family from your floor came this morning and handed in more than 100 kilograms." Jiang Ning nodded, "Well, there are rats everywhere in our place, and we can't do anything." The canned food is exchanged once every half a month, and the two left after handing in the goods. At this time, the sun had set, the summer heat had dissipated a little, and the survivors began to move around. After the extreme cold, the number of rubber boats and assault boats decreased sharply, and they would stay away from people if they met them, so as not to be robbed on the water. Even if you go out in the evening, the temperature has reached 50 degrees. Although you have constant temperature clothing as a base, the perceived temperature is not low, not to mention that the protective clothing is not breathable . Back on the 18th floor, both of them were wet in their clothes. Jiang Ning went into the space to take a shower, and then took the dogs to 1801 for dinner. The two dogs were bored in the house for a whole day, and even with the air conditioning fan, they were wilted, shivering and had no appetite. Jiang Ning was the same, and whispered to Huo Yishen, "Eat cool skin?" The goods were stockpiled by Jiang Ning, and he had no objection, "Okay." She took out a dozen cucumbers from the space and taught Huo Yishen how to beat the cucumbers. A lot of food was made, so after breaking it up, it had to be mixed in a large basin, leaving enough for three people, and the rest was stored in the space. It was sour and spicy and refreshing, and it immediately whetted my appetite. The dog can't eat spicy food, so some goat milk was added to the dog food and a piece of chicken breast was added. For several days in a row, more than 100 kilograms of mice were collected on the 18th floor every day. People downstairs couldn't help but mutter, "Strange, why are there fewer mice?" The operating range of the mousetrap is 30 meters in diameter, and the mice affected by the sound waves run to the upper floors. Mice can swim, they swim, and if there are fewer in unit 1, other places will make up for it. So, the other floors followed suit. It is true that red-eyed mice are ferocious, but as long as you are careful to prevent yourself from being bitten, you will have a chance to catch them and fill your stomach. While they were in doubt, the municipal government issued an announcement that scientific researchers had successfully developed a mousetrap, and that workers would come to kill rats soon. Then, a funny scene appeared. Many survivors blocked the gate of the community and prevented the workers from entering to work. They had no control over whether others lived or died, but if all the rats were caught, how would they live? Even the neighborhood committee’s visit to do ideological work was useless. Blocking the door was useless, as the large mousetrap brought by the workers had a working diameter of up to 100 meters. They pretended to leave, but actually turned a corner and started working outside the community. Then, a shocking scene appeared, with many drunk rats appearing in the water, swimming swayingly in the water. The workers directly caught them with a net and threw them into the iron cage.

However, they were still discovered by the survivors. Some of the brave ones even paddled over in assault boats and stretched out their hands to ask the staff for

the rats, saying in an extremely excited tone, "If you catch them all, how can we survive?" The staff dared not give them anything. Many people died from eating rat meat, and rat meat must be sterilized at high temperatures.

Of course, they also understood the difficulties of the survivors, and tried to be gentle to avoid conflicts. If it was really impossible, they would retreat first.

After more than half a month of continuous rat catching activities, the number of red-eyed rats in various districts of Fengcheng has dropped sharply.

Even if the mousetrap is turned on, only about 10 to 20 can be caught in a day.

At the same time, the neighborhood committee will distribute special cockroach medicine.

Jiang Ning received a few copies when he delivered the rats, and it was indeed very effective. The big cockroaches were finally eliminated.

The 18th floor celebrated, and the only unhappy ones were the rabbits, as they had to eat grass again.

The extreme heat continued, and Fengcheng was cooking in pots every day.

The tortured survivors were half-cooked and spent every day wailing.

Extreme heat, lack of water, lack of food, hunger...

For them, the only good news was that the filtered water came out.

No one cared how the water came, and no one dared to think about it. What they worried about was how to get the water back?

They hadn't taken a shower for a month, and their bodies were sweaty and oily. They didn't even dare to look in the mirror.

Some people who were smart and sharp followed the trend and stockpiled water in advance, so they could still get by.

Life is full of different situations, people's livelihood is difficult, and wailing is endless.

On this day, Jiang Ning and Huo Yishen went to send the mouse away. Just as they reached the corner of the fifth floor, they saw a snake coming out of the water and swimming along the stairs...
