After Qiao Qingqing and the other two brought the crow corpses home that day, they did not change their clothes for the time being. Instead, they carried buckets to the toilet and plucked the crows, cleaned them, and removed their internal organs. After being processed, the crow corpses were about the same size as an ordinary three-yellow chicken. No one knew what they had eaten to cause their bodies to expand to such a size.

"Corpse." Qiao Qingqing said.

"Hey Qingqing, why did you say that?" Qiao Songzhi sighed.

Ever since her daughter said she wanted to pluck the crows' feathers, she knew what she was thinking. If she wanted to sell them, there would be no need to go through so much trouble. She must be planning to keep them for her family to eat in the future.

Qiao Qingqing's voice was full of laughter, coming out of the mask in a muffled voice: "It's okay, as long as it's cooked thoroughly, it's edible, but the taste is not so good. But don't worry, we won't eat this for the time being, I just want to clean it up and store it, and then... I'll eat it later if I have no other choice. After all, it's meat."

"When there is nothing to eat, you can even eat dirt. These are meat after all," said Shao's mother.

After collecting all the crows, Qiao Qingqing placed them in a large bucket, sealed it with a lid and put it in the space to keep it fresh. Then the three of them took off their protective clothing, took a shower, changed clothes, and disinfected the toilet. The plucked feathers were collected and taken out for disposal when there was an opportunity.

Three days later, the base once again welcomed a large number of crows, this time the number was far greater than the previous batch. They attacked from different directions, and the speed of trapping could not keep up with the speed of their invasion. Soon the crows were wreaking havoc everywhere in the base, causing many casualties.

From time to time, someone would be attacked on the road and scream in fear. Some people in the community would come to Qiao Qingqing to treat their wounds, which were so deep that the bones could be seen.

"It keeps bleeding. Can you help me deal with it, Doctor Qiao?"

Qiao Qingqing was able to treat the wound. Seeing the wounded man bleeding and turning pale, she hurried to stop the bleeding. However, she still had to remind him, "Crows are not clean. You should go to the hospital and get a blood test to see if you need any vaccinations."

After everything was done, the injured person's family left two big potatoes and helped their husband go away. Before Qiao Qingqing closed the door, she cleaned up the blood dripping from the injured person on the ground.

There were more and more crows, some of which flew into Building 20. Qiao Qingqing and the other two killed all the crows that attacked again. It was the first time Chi Yuxiu saw them kill crows with her own eyes, and she was amazed.

"The weapons you are holding are bows and crossbows, right? You are so awesome."

"Do you want to learn? I can sell you a set. Neighbors have a preferential price." Qiao Qingqing said with a smile.

Chi Yuxiu waved her hands quickly: "I can't do it, no need."

However, Chi Yuxiu felt bad for her neighbor's hard work in killing crows, so she sent some gifts to Qiao Qingqing's house. Seeing that there were not many gifts, Qiao Qingqing did not say anything polite to her. Gradually, the neighbors downstairs also knew that the crows that entered the building were killed by the seventh floor. Some people were better at social etiquette, and either sent one or two gifts, or simply said a few words of thanks.

They were like the heroes of Building 20 and received a lot of praise from people, which made Shao's mother and Qiao Songzhi excited and happy.

Some people felt grateful, but naturally there were also people who felt that Qiao Qingqing's family had taken advantage.

"Your family has taken over so many crows, you should at least give us some, right? Not all crows belong to you, some were lured away from our home by you, we should also have a share!"

The person who said this sounded very confident, but the people who heard it just thought it was a fantasy.

Through the iron gate, Qiao Qingqing said to the neighbor who claimed to be here to seek justice: "From what you said, I am still wrong. If you want to settle it this way, I will return the crow corpses to you. You can take as many as you want."

The whole family looked happy.

"You have to pay me back for the cost of killing the crows. I don't do useless work, nor do I do charity."

"How much do you want?"

"My crossbows and arrows are all handmade. One arrow costs one pound of food. Every time a crossbow is shot, it will be damaged. The maintenance cost is also half a pound of food. My skills are perfect, and my price is not cheap. If you ask me to hunt crows, you have to pay me five pounds of food for each one I kill. For the sake of our neighbor, I will give you a discount. You can pay me six pounds of food for each crow."

"W-what?" the man shouted, "Why don't you go and rob!"

Qiao Qingqing sneered: "I'll give this sentence back to you."

"I don't care, you give the crow back to me, or we won't leave!"

"Whatever." Qiao Qingqing turned around and was about to go into the house.

"Qiao Qingqing! Don't go too far, I'm not a pushover!" As soon as she finished speaking, Qiao Qingqing heard the sound of something hitting the door behind her. She looked back and saw the man chopping the iron door with a kitchen knife. He probably just wanted to threaten Qiao Qingqing, and he stopped when he saw her looking back. He stood on the steps, raised his head, and threatened: "If you don't listen to reason, I will be rude to you."

"Qingqing——" Qiao Songzhi and Shao's mother called her worriedly.

Qiao Qingqing gave them a soothing smile: "Mom, don't come out." Then she turned her head.

"That's great. I don't want to reason with you either." She walked back quickly, grabbed the man's hand that was holding the iron gate, and pulled it hard. The man fell on the iron gate, his wrist was pinched by Qiao Qingqing, and his fingers couldn't help but loosen, and the kitchen knife in his hand fell to the ground.

"dad!"

"husband!"

The man was frightened and angry, and wanted to use his other hand to resist, but was held by Qiao Qingqing. She freed her other hand, drew the knife from her waist, and put it directly across the man's neck.

"... You, calm down." The man regretted it very much. He had never expected Qiao Qingqing to be so strong! He struggled, but his hands could not get free. He was hung on the iron door like a frog. The cold blade pressed against his neck, making him shudder. He had a hunch that Qiao Qingqing really dared to make him bleed.

His intuition was correct. Qiao Qingqing ignored him and gently scratched the man's neck, cutting the skin and causing blood to flow out.

"Husband!" the man's wife screamed in fright.

"Remember, I, Qiao Qingqing, am not a pushover. If you dare to cause trouble again next time, I will cut you deep. Do you hear me?"

"I heard it! I heard it, I heard it! Doctor Qiao, please let me go. I won't dare to do it again next time!"

Qiao Qingqing wiped the knife on his face to clean the blood, then let go of his hand: "Get lost."

The man's hands and feet were weak, and he was helped down the stairs by his family, with his child following behind him, crying loudly.

"Doctor Qiao, you really are this." Chi Yuxiu gave Qiao Qingqing a thumbs up and closed the door.

"Qingqing, are you okay?" Qiao Songzhi and Shao's mother came over.

"It's okay, I'm fine." Qiao Qingqing smiled, "You guys go back first, I'll go to the sixth floor to water the vegetables, and then go downstairs to get some water."

"Let me accompany you." Qiao Songzhi insisted on going out together, and Qiao Qingqing couldn't stop him.

The two of them went to the sixth floor to water the vegetables, and then carried the bucket downstairs. When they passed the fourth floor, Qiao Qingqing could hear the noises of the family, the children were crying, the adults were crying, and the man yelled, "Stop crying! Aren't you ashamed?"

Qiao Songzhi rolled his eyes: "I think he is the most embarrassing one."

They continued to go downstairs. There were still many people queuing up to get water at the deep well. The reason was simple: crows had polluted half of the deep wells in the community, including the deep well near Building 20, so Qiao Qingqing and Qiao Songzhi had to go to another deep well 500 meters away. There were many people and few wells, so naturally they had to queue up. When queuing to get water, people had to be careful and alert to the sky, for fear that crows would come to disrupt the situation. If crows invaded, they would not only have to retreat quickly, but also cover the well cover before retreating, otherwise the well would be useless again.

During the incident, some residents got into conflicts and started fighting, which attracted the patrolling security team, and everyone was warned.

"It's not easy to get water these days." It took two hours to get water. Qiao Songzhi was very touched. "Have you noticed? People's tempers are much worse than before. They will quarrel over a small issue."

"Maybe it's because of the stress of life." Qiao Qingqing put down the water and opened the door of 601. The water they fetched was used to water the vegetables and feed the chickens. The chickens at home were growing well, but the attack of crows obviously made them feel the fear from their natural enemies. Every time the crows came, they were frightened, flying around in the chicken coop, clucking and crying, and they couldn't eat the feed anymore. Qiao Qingqing purchased a lot of chicken feed before the end of the world. They ate it happily and grew meat quickly. Seeing that the chickens stopped growing meat after just a few days, Shao's mother was angry and anxious.

"In two more months, the hens will start laying eggs. Alas!"

"It's okay. This is called survival of the fittest. Those who survive will be stronger." Qiao Qingqing said, "Those who don't survive will be used to make roast chickens."

"Okay, roasted chicken, it sounds delicious." Qiao Songzhi made himself optimistic.

Suddenly there was a knock on the door. Qiao Qingqing looked through the peephole and found that it was the security team. She had some ideas in her mind. She opened the door and saw the family standing next to her. When she saw her come out, the man’s wife pointed at her and shouted, “She was the one who hurt my husband with a knife! The security team will arrest her and put her in jail!”

There were two people from the security team. The older one asked Qiao Qingqing, "We received a report that you injured someone with a knife. Do you have anything to say?"

"Comrade Public Security, my daughter didn't wield a knife to hurt anyone!" Qiao Songzhi rushed out upon hearing the noise and explained, "This family came to my house to cause trouble and even chopped my iron door with a knife. My daughter was defending herself!"

"You're talking nonsense! It was obviously Qiao Qingqing who did it on purpose. She wanted to kill my husband!"

"Mom." Qiao Qingqing grabbed Qiao Songzhi and said to the security team, "My mother is telling the truth." She told them how the man and his family came to her house to cause trouble.

"I don't think I did anything wrong, and the wound on his neck was just a little skin break, it will heal in a few days."

She looked him straight in the eye: "My neighbor can testify to that."

"You are making excuses! I——"

Qiao Qingqing looked at the man with a calm look, but the man was speechless.

At this moment, Qiao Qingqing thought to herself that she had chosen to fight for the opportunity to enter the new community for the safety of her family's living environment. Since it was for the order here, it was normal for her to be bound by the order now. If she was outside the base now, in such a chaotic and difficult-to-govern area, she could easily find an opportunity to kill him and there would be no future trouble.

But here, she could only cut the skin on his neck to intimidate him...

The security team signaled to the man and his family to calm down. The man found a way out and shut up. He didn't dare to think about the look from Qiao Qingqing just now. At this time, he had already backed off.
