Wu Wei is a very good at dealing with things. He immediately patted his chest with a confident look on his face, "Don't worry, classmates, I'll cover you!"

Wu Wei's father is a builder and is considered a powerful local tycoon. He is a personal talent. He has long realized that Liu Xin will be an amazing person in the future, so he asked Wu Wei to assist Liu Xin unconditionally.

Wu Wei's physical fitness is close to that of a junior physical education teacher. People like him will generally be recruited by major forces after graduating from high school, so ordinary teachers in the school really can't control him.

Wu Wei has always listened to Liu Xin's words, but after a while, a monster has really come. It's different whether he can get on or not.

Liu Bi and Liu Sha on the side also echoed: "With Angkor here, don't be afraid!"

Tang Yun didn't like to attract attention, but just nodded, expressing his agreement with Liu Xin's statement that it is most important to stabilize the emotions of other students at present.

Everyone climbed up the hill and started walking back from the road.

The students walked alertly. Seeing that there was no danger for the time being, Tang Yun started chatting with Liu Xin.

"Teacher Liu, if the little mushrooms that grew in my wound before were not removed, they would grow into monsters' red bumps in the future, right?"

Liu Xin's answer was very concise, "Yes."

"I heard from Wu Wei that you don't let the small mushrooms be pulled, otherwise you will pull off the flesh and blood."

"Yeah, it's already taken root."

Wu Wei, who was standing aside, interrupted, "I can't understand. If I pull the mushroom, Tang Yun would probably die of blood loss. How can the mushroom continue to spread?"

Liu Xin: "Do you think that monster is dead or alive?"

Wu Wei was stunned. He was really unable to be sure of the life or death of the monster. He felt that the zombie was almost the same.

"No...I don't know..."

Liu Xin: "Life or no matter how important it is. Anyway, consciousness must be controlled by the red lump. By the same token, Tang Yun's life or no matter how important it is. The red lump will stop bleeding and let him act like a monster."

Tang Yun frowned: "Teacher Liu, I always feel that something is abnormal in this world, but I can't tell why, it just feels something is wrong!"

Liu Xin glanced at Tang Yun and looked back in front of him.

"It just feels...but you feel very accurate."

Liu Xin took out a small instrument from his bag and said to himself: "The earth's rotation has slowed down."

Wu Wei: "What? Isn't this something that happened a hundred years ago?"

Liu Xin: "No, the speed of decreasing has accelerated. My device can sense the speed of the earth's rotation. Although I cannot connect to the Internet now, once the latitude and longitude are determined, the speed can be accurately measured."

Wu Wei: "I heard what you said, everyone has never had a network in their hands. The signal shutdown has been too long this time, and it hasn't been so long before!"

Tang Yun: "Teacher Liu, when do you think the earth will stop?"

Liu Xin: "This is not clear, it is hard to estimate. It may take hundreds of years or several years, and the trend of slowing down cannot be determined."

Wu Wei: "What? How many years may it be? What are the consequences?"

Liu Xin: "Okay, let's continue to teach you a lesson!"

Liu Xin clapped his hands and attracted the students' gaze.

"Students, here are some knowledge for everyone. If you want to listen, listen, and do your own things if you don't want to listen."

Liu Xin turned around and looked at Tang Yun and Wu Wei, "You two have the best perception ability here, so you must be alert!"

Liu Xin continued to tell the students, "You can't use this knowledge in the exam, so just take it as learning extracurricular knowledge."

"These are all theories and may not be completely correct. I will choose some of the papers I published to explain to you in a common way, and there will be no specific model operations and data..."

"You already know that because of the rotation of the earth, there will be alternation between day and night. There are times difference and earth-turning bias forces, which will promote global water and heat flow..."

"If the rotation slows down, what changes do you think will happen to the sea water?"

The students started to talk.

"How can this change?"

"Yes, is it frozen or evaporated?"

“Is there any connection?”

Liu Xin reminded: "You should open your mind a little. The earth is an irregular sphere with slightly drums in the middle and slightly flattened poles. Then consider the deviation force."

Although Tang Yun had excellent grades, he was a science student and these problems were obviously beyond the syllabus, so he had to listen to Liu Xin's explanation while being alert.

At this time, a girl raised her hand hesitantly. This is the class leader Xiang Yu, who looks ordinary but has a gentle personality. She is a standard academic master.

Liu Xin nodded: "Don't raise your hand, say whatever you want!"

Xiang Yu replied: "The sea water flows to the extreme south and extreme north..."

The north and south ends of this world are called the extreme south and the extreme north, and are both continents covered with ice and snow.

Liu Xin: "Yes, once the rotation force is weakened, the sea water will flow to the poles. I'll ask you again, how does the air flow?"

This time, Xiang Yu was obviously more confident and raised his voice and replied: "The air will move to the poles just like sea water!"

Tang Yun was shocked. Although Liu Xin did not ask about the consequences, he realized after a little thought that when the air was thin, not only humans, but most creatures would be destroyed!

Liu Xin did not raise the topic in a heavy direction and asked again.

"The earth is divided into three layers, a molten core, a solid mantle that isolates, and a hard crust. They all rotate together. But what happens when the rotation speed slows down?"

Xiang Yu: "Is it earthquake?"

Liu Xin: "Yes, the speed of each layer drops is different. Finally, the powerful friction is suddenly released and tear it from the inside out..."

Liu Xin originally wanted to continue saying, "Earthquakes will also occur in areas where earthquakes have never occurred before," but he still didn't continue to mention them.

"You don't know the issue of magnetic field, so I'll talk about it directly. The geomagnetic circle formed by the magnetic field protects the earth, and this electric field is maintained by the rotation of the earth. However, if the earth's rotation slows down and the magnetic field weakens, the radiation from outer space will reach the earth."

Xiang Yu's expression was a little unnatural, "Then...will that kill humans directly?"

"That won't be..." Liu Xin seemed to realize that he was saying too much and waved his hand. "The geomagnetic reversal has happened many times before, and it will also be accompanied by the weakening of the magnetic field. As long as it is not greatly weakened, the creatures are not that fragile. Well, I think you are all energetic, so keep moving forward."

Liu Xin felt a little bored. Xiang Yu pointed him out, and the creatures would not become extinct easily, but instead evolved even more crazily based on the previous ones.

Moreover, the Earth's rotation slowdown brings a series of effects. I didn't explain it to the students in detail, and the current situation is even more serious.

At this time, Wu Wei approached Liu Xin and asked with his big eyes eager for knowledge.

"Teacher Liu, what will happen if the earth suddenly stops its rotation? How can we deal with it?"

Tang Yun secretly laughed at the side, "Why is a poor student joining in the fun?" And is this problem meaningful? How to deal with it suddenly stops at such a fast speed?

Liu Xin sighed and looked at Wu Wei with caring and sympathetic eyes.

"The equator turns more than 400 meters in one second. If it stops suddenly, all animals and plants on the surface will be destroyed directly except for the low latitude! As for the undead creatures, just wait slowly in the day of the year, just..."

Wu Wei muttered: "Is 400 meters in one second faster than my Baodu off-road vehicle?"

Liu Xin shook his head and ignored it and continued to move forward. Wu Wei asked simple questions that middle school students could figure out by themselves.

Liu Sha came over and said, "Angkor, how can you be as fast as your donkey cart!"

Liu Bi also smiled and said, "That's right, Angkor is a sports teacher and runs faster!"

Wu Wei nodded with satisfaction: "Although you two are not very smart, you like to tell the truth. When you graduate, I will take you to have fun and have a good time!"

Liu Bi: "Angkor is high! His grades are naturally better than us!"

Liu Sha: "Angkor is hard! His head is naturally smarter than us!"

The two looked at each other and smiled, and said in unison: "Angkor is tall and hard!"

Tang Yun, who was standing beside him, felt goose bumps and couldn't help but avoid these students with the top three in the last grade...

Chapter completed!
