The better-off ones had raincoats to wear, those with worse conditions wrapped themselves in a layer of plastic sheeting, and those with even worse conditions just covered their heads with something random.

There was a thin man who was even holding a piece of wood above his head. Occasionally, raindrops hit his hands, and he could only shiver.

You can't just hold it up. If the wind is strong and you don't hold on tightly, the board will be blown away and your head will be in trouble.

However, these people were crowded together, and those squeezed in the middle could feel a little better, at least they would not be suddenly hit by the acid rain carried by the wind.

But the people outside were in a miserable situation, so everyone was shouting and pushing each other to get inside.

This scene reminded He Xiaobei of those animals that live in groups. When winter comes, many animals will huddle together to keep warm.

However, animals know to change positions occasionally and cannot withstand the cold wind alone all the time. In this way, animals are stronger than humans.

These people shouted for a long time, but there was no response from inside. The frustrated people would shoot a few shots at the door to vent their anger.

However, the towering walls outside the research base prevented these people from getting in. They could only keep lowering their demands, and in the end, they could only beg.

"It would be better if we could get inside to avoid the rain. The acid rain has burned our skin."

When He Xiaobei thought about this, he felt that it was a good thing that he had put Yingying into the space before. Now there was only a house left, and the outside was covered with ice by her.

There is still some ice and snow halfway up the mountain, so her house is not conspicuous. Otherwise, after these people enter the base, she will be the first to be besieged by them.

Just thinking about that scene was enough to make her headache. She couldn't just kill them all, could she? But if they refused to listen and did something bad to her, she might not refuse to do so.

After watching the excitement, He Xiaobei returned to his residence, but the shouting outside did not stop at night, occasionally accompanied by screams.

In the end, she simply packed up the house and the bodyguards, and went into the space to sleep.

When we came out the next day, the people outside were still shouting, and the group was a little bigger than the day before. They clung to the outer wall of the base to reduce the damage caused by the cold wind and acid rain.

He Xiaobei was eating a bun while observing with a telescope. Accidentally, a drop of acid rain fell on the bun. The white skin of the bun instantly turned yellow where the acid rain fell.

She took a deep breath and silently stored the bun in her memory. In the apocalypse, this bun might be worth more than a life. Eating was always wrong, but wasting was always wrong, so He Xiaobei kept saying "sin, sin" in her heart.

After thinking about this, her delicate eyebrows frowned again, because she remembered the acid rain described in the novel before, which corroded everything. So she quickly took out the bodyguard and connected it to Qian Chenxi's communication.

After telling the other party about his worries, he made the other party laugh:

"What are you thinking? This is acid rain, not sulfuric acid. The pH of acid rain is only 5.6, and the pH of concentrated acid rain is only 4.2-4.4. What we are experiencing now is heavy acid rain, with a pH of around 4.2, not the level you are describing."

He Xiaobei is still a little worried:

"But just now, acid raindrops fell on my buns, and the skins turned yellow."

Qian Chenxi looked at her through the video with a strong look of disgust:

"That's because acid rain contains acidic substances such as sulfuric acid and nitric acid, and the bun wrappers contain organic matter such as starch. The acidic substances cause the structure and properties of the organic matter to change, causing yellowing."

After he finished speaking, he sighed:

"Can you tell me some useful information or interesting things? Every time you call, you ask me these low-level questions. I feel like my robot is being wasted by you."

He Xiaobei's eyebrows raised, and his smile instantly collapsed:

"Haha, I sent back so much information and so many instruments and equipment to the base. I don't believe the base didn't give you a share of the spoils."

Qian Chenxi was immediately embarrassed. He did get a lot of things and information. Just as he was about to open his mouth to argue, He Xiaobei glared at him, and then the call was hung up.

After He Xiaobei hung up the phone, she pouted. Being looked down upon by someone so much younger than her, didn't she have any dignity?

She had always been a poor student when she was in school, and she felt that what Qian Chenxi had just said to her was just a compressed package stuffed into her head.

She didn't understand, but she knew the situation wasn't as bad as she thought, so she just continued to watch the fun.
