System into the end of the world

Chapter 80

After closing all the doors and windows, Zhan Xuyang packed up a few simple things and took Yu Nan and Jia Jia up to the topmost attic with the glutinous rice balls.

The partitions of the attic windows had been closed for a long time, Zhan Xuyang signaled Jiajia to do it herself, asked Yu Nan to help hold the flashlight, and he opened the steel plate on the north window by himself.

The rain outside the window was still pattering down, but there were a few more black shadows occasionally protruding half of their bodies in the ponded water on the ground. "Is it a zombie rat?" Yu Nan asked looking at the shadows.

"Mutated rat." Zhan Xuyang shook his head. "This rain has been falling for too long, and it has flooded out the mutant mice hiding everywhere."

"Where is the little uncle?" she asked.

"It was my little uncle who called me. If he hadn't reminded me, our house would have been almost infested with rats." Zhan Xuyang said with a frown.Yu Nan didn't speak anymore, just stood at the window with Zhan Xuyang, looking outside.Jia Jia spread out a mat in the corner and sat on her knees holding glutinous rice balls.

The number of mutated mice is increasing. At the beginning, only a dozen were seen, but in a short while, it became dozens.They vary in size, the small ones are more than a dozen centimeters, and the big ones are sixty to seventy centimeters. The distance is a bit far away. Yu Nan can only judge their size according to the reference objects.

Human screams came from far and near, Yu Nan felt chills and shivered uncontrollably.Zhan Xuyang wrapped her in his arms and hugged her tightly. "They eat people." She seemed to hear the sound of her teeth chattering.Not to mention the mutant rats, even the rats before the end of the world, I am afraid there is nothing they can't eat. If they are given a chance, they can even bite off a piece of human flesh.

If they were allowed to find food, I'm afraid this simple red brick wall really wouldn't be able to stop them.

"What should I do? There's still so much food in the kitchen downstairs." Yu Nan couldn't help shaking again.

"Although mice are omnivores, most of the time they are vegetarians. I just threw all the edible things out of the window. Then" he pointed to the northwest direction.There is a courtyard wall over there, which is another newly built house. Because the house has not been completed yet, no one has lived in it for the time being.He couldn't see what was going on behind the wall, but Yu Nan could make a rough guess just by listening to him.

"Mice have a keen sense of smell, and now we can only hope that the rain will cut off the smell on us..."

The unfinished meaning in his words shocked her, "Then what should I do? Is there any way... How about sprinkle some vinegar on your body? Or perfume?" She asked helplessly.

Zhan Xuyang hesitated for a moment, then nodded, "Give it a try, you guys stay here for a while, I'll go downstairs to get vinegar." After saying that, he was about to turn around and leave.

"Wait!" Yu Nan grabbed him almost subconsciously.At this moment, there are already a few mutant mice wandering around in the courtyard downstairs. If Zhan Xuyang goes down, the mice will find him if he fails to keep them together.

"What's wrong?" Zhan Xuyang stopped and looked at her questioningly.

"I..." Yu Nan clenched her fists, feeling extremely conflicted in her heart.At first, she made up her mind to hide the matter from the system until she died, but now that human life is at stake, even if there is a system, she still has no way to be 100% safe, should she say it or not?How much do you say?These are issues that must be faced right now. "I will go with you."

"No, you stay here, I'll go alone, the goal can be smaller." Zhan Xuyang shook his head gently but firmly, opened the door and rushed out.

Yu Nan was in a daze, and the others disappeared. Gritting her teeth, she immediately followed. "Zhan Xuyang!" She didn't dare to shout loudly, but Zhan Xuyang should be able to hear it in this corridor.He suddenly stopped, stopped in place, turned back and looked at her fiercely, "Didn't I tell you to wait up there? Why did you still run down!"

"I...you come in with me!" She couldn't care about anything else now, she dragged Zhan Xuyang into an empty room on the third floor.It was so dark inside that she couldn't see his expression clearly, "Wait." Yu Nan opened the system mall, bought two bottles of old mature vinegar, and stuffed them into his hands without saying a word.

In the darkness, the breathing of the two people seemed to be amplified countless times, Yu Nan's heart was hanging high, afraid that he would ask.

After a while, Zhan Xuyang took her hand and walked out, "Let's go." There was a hint of a smile in his voice.

"Huh?" Yu Nan was caught off guard by his reaction, and let him drag her back to the attic in a daze.

Of course, Zhan Xuyang couldn't pour vinegar directly on the person, but sprinkled it around the corner of the wall.The pungent vinegar smell immediately filled the entire attic, making it even more difficult to breathe.I don't know if it was her illusion, it seemed that the mouse that was about to swim to the side of the building was farther away.

"Woof..." Tang Yuan lay limply on the ground, scratching her nose with her front paws.Jiajia also held her breath hard, and gasped with her mouth when she couldn't bear it anymore.

"..." Yu Nan looked around silently, went out for a while, and came back with four filter masks in his hands.It was distributed to the two of them, and Yu Nan put it on herself. There was a small mask left over the nose and mouth of Tangyuan after a little processing. "It still has some effect, but I don't know how long it can last."

"That's great, it's really useful." Jiajia whispered, and then obediently huddled in a corner.

Yu Nan glanced at Tangyuan who couldn't help but sneezed, feeling a little sorry.The dog's nose was inherently sensitive, so it would undoubtedly be hard for him to stay in this room, but she was worried about it leaving, and only hoped that Tangyuan's nose would still be functional when they left the attic.

There was a sound of splashing water outside, and Yu Nan and Zhan Xuyang immediately went to the window. Not long after, they saw a man running out from a distance stepping on the water, with a big mouse biting on his neck. There was a lot of blood on it.As he passed by, rats kept chasing him, or jumping out of the water, tearing strips of flesh from his body.

"Ah..." He staggered and fell into the water. Immediately, dozens of mutant mice surrounded him, wriggling densely.The blood color smeared in the water, and after ten minutes, there was not even bone residue left.

"Evil..." Resisting the churning in her stomach, Yu Nan opened her eyes wide and tightly covered her mouth. "Is there no way to kill these rats?" she whispered.

"The method of burning the zombie bird last time can be used again this time, but in this weather..." He sighed.The effect will be greatly reduced. "Or there is another way."

"What?" Yu Nan asked immediately.

"Cat. Mutated cat."

Yu Nan pursed her lips and said nothing.The glutinous rice balls were raised when they were puppies, and the mutant silkworms were also hatched from eggs. There is no more experience to learn from. She is not sure whether the adult mutant cats bought from the mall will listen to her. If it is a kitten , it probably won't have any effect on the mutant mice outside.

Zhan Xuyang's cell phone in his pocket suddenly rang. He quickly covered the speaker, pressed the answer button, and walked a few steps away from the window.Yu Nan forced herself to stand where she was, staring at the pool of blood that was getting lighter and lighter in color until it returned to the color of mud.

The view from the window is limited, Yu Nan can't observe much, but it doesn't hinder the transmission of sound.The intermittent screams and broken glass made it easy to guess what happened outside.From the zombie bird last time to the mutant rat this time, a large number of people would die every time they encountered an attack. In front of these previously inconspicuous animals, human beings became completely weak.

It seemed that there was a sound of "booming" coming from a distance, mixed with various sounds, it was not very real.

After a while, Zhan Xuyang came back and said that Cheng Yongzhi was surrounded by mice, and now he was counting on Zhou Yi's metal ability to seal all the doors and windows, and he could block them for a while. "Passive defense is not an option. The more noisy they are, the more rats will gather. I'm afraid even we will suffer together."

The sound of "boom boom" was getting closer, and Yu Nan remembered that it seemed to be the sound of a flamethrower.So she turned her head and looked at Zhan Xuyang, "What do you think of us passing two flamethrowers to Brother Cheng?"

"..." Zhan Xuyang didn't know what kind of expression to change into, "The two nearest windows of our house are at least ten meters apart, how do you send him there?"

"Uh..." Yu Nan scratched her head, she didn't know either. "How about asking Brother Zhou to get a basket or a hook and pass it over, so we can hang it up for him and upload it?"

Zhan Xuyang also felt that the state of the two of them was a bit funny, curled the corners of his lips, and looked down, "Wait a little longer, the rescuer should be very close, maybe we don't need to take action at all."

"Okay." Yu Nan looked at him and naturally had no objection.

Zhan Xuyang was right. About half an hour later, they saw a group of soldiers sweeping towards the water surface with flamethrowers. Everywhere they passed were dead rats with their bellies turned upside down.

The sound of "squeak" pierced people's eardrums, and a very familiar smell of barbecue came in through the cracks in the window.

"Maybe someone will eat rat meat." Yu Nan said suddenly.

"I hope they remember to send it to the research institute for testing before eating." Zhan Xuyang showed a smile that couldn't tell whether it was irony or pity, obviously thinking that the possibility she said had a great probability of happening.There are many people who have not eaten meat for several months, but not everyone can resist the temptation when countless meats suddenly appear in front of them.What's more, not all murine species can't be eaten. Isn't bamboo rat a very popular ingredient in the south!
The soldiers quickly walked out of their sight, Yu Nan and Zhan Xuyang stood still, quietly waiting for the development of the situation.

"It's coming again." Zhan Xuyang nodded diagonally forward.

Yu Nan easily found the place he was pointing at among a group of dead rats. Those newly arrived mutant rats were eating the corpses of their own kind.The blood spread again and became thicker and thicker.

"It seems that using fire is indeed right." Yu Nan grinned.The temperature of the flamethrower can reach 800 to 1300°C, and certain ingredients are added to the fuel so that it can burn in water. It is absolutely no problem to deal with mice. Unfortunately, the fuel is not durable and will be used up in a few seconds. It's only a few minutes long.She opened the mall to look through various flamethrowers, and suddenly saw a new update notification.

Click OK, and immediately after the update is completed, there is a new model, and it looks familiar. As expected, it happens to be the one carried by the soldiers who passed by just now, and the effective injection time has reached 30 minutes.

For the update, she has figured out some ways.Whether it was the protective clothing last time or the flamethrower this time, it can only be turned on when it comes into contact with items that are not in the mall.But after turning it on, it doesn't stop at updating the items she sees, but an update of the items that actually exist in this space.

But the old item will not disappear (even if it no longer exists in reality), which leads to the options that she searches every time ranging from dozens of pages to thousands of pages. People get dizzy.Fortunately, there are conditional options to filter, otherwise it would take up a lot of her time just to read the instructions.
