Rebirth before the doomsday: I quietly emptied the city of supplies

The two of them quickly put on their clothes and called all the women's gang members as quickly as possible. There is an underground air-raid shelter here.

When the troops were stationed there before, the underground air raid shelter had actually been completed. Everything was ready, except for the heating equipment.

Chen Yu happened to come over, and he had several sets of finished crystal core energy converters with him, so he just left two sets here. Anyway, there were plenty of crystal cores.

Two sets of energy converters are sufficient to meet all the electricity needs of these thirteen women.

During these two months, Chen Yu also took the time to bring the thirteen women to Changcheng and surrounding cities to plunder countless electric heaters and various heating equipment. As long as there is enough energy, these equipment can be used for ten or eight years without any problem.

All day long.

Chen Yu and others completely arranged the underground air-raid shelter.

Then they spent another two days storing the collected daily necessities downstairs and sorting all the weapons into different categories. Even though these women didn't need weapons anymore, it was better to be prepared.

At dusk on the third day.

The temperature has already begun to plummet.

Chen Yu and the thirteen women had already taken refuge in the underground air raid shelter. He had to make sure that everything was ok before he could leave.

It would be even more perfect if these thirteen women could rely on the nuclear fission energy in their bodies to withstand the extreme cold weather. So Chen Yu had to stay for another day.

As the sky outside grew darker, a fire had been lit in the air raid shelter, and even five or six electric heaters were set up. Everyone was very nervous.

Sudden.

Liu Shuyun screamed, turned her head and looked at Chen Yu in surprise, "Oh no, we forgot someone." "Who?"

"It's the math teacher Zhang Yong. He's still living in the guard room outside." "..."

Chen Yu frowned slightly. Chen Yu had met that person before. He was still unsure of who he was.

It is a miracle that he can survive to this day with the will and physique of an ordinary human being. Such people are rare.

So Chen Yu did not expel him and let him live in the guard room outside.

Occasionally I would go over to take a look and bring him some food.

Chen Yu would not easily accept survivors. Everyone he accepted had to pass his observation and test. If they failed, he would not show mercy.

But I was busy playing poker with the Thirteen Girls and building an underground air-raid shelter for the night, so I forgot about that person. If I didn't take care of him, he might not survive tonight.

After thinking for a moment, Chen Yu turned around, put on his coat, picked up his hat and whispered, "I'll go see him." The girls nodded at the same time.

Chen Yu quickly rushed out of the air-raid shelter and ran outside.

At this moment, the temperature outside has dropped to about minus 35 degrees. It's already very cold. White air comes out of his mouth. That guy doesn't have any heating facilities. Could he have frozen to death?

It's strange. I haven't taken care of him for a while, and he hasn't come to ask these people for help? Could he have died a long time ago? Chen Yu was suspicious.

I rushed to the guard room at the gate as fast as I could. When I got closer, I saw a fire inside. It seemed that he was not dead yet.

He is really persistent.

Chen Yu approached quietly, but did not go in. He just listened quietly at the window for a while, and used the mental map to observe his actions.

There was a faint coughing sound inside.

He is walking up and down.

He was mumbling to himself, but no one knew what he was saying.

After listening for a long time, Chen Yu looked suspicious.

This guy is actually deriving a formula?

Crazy?

It was so cold outside, but he didn't even bother to ask for help inside. He was actually deriving some kind of damn formula in this kind of place. He must be a math teacher. I'm going crazy.

However, the more he acted like this, the more Chen Yu trusted him.

For a person like this, his energy has been infinitely magnified in a certain field, even transcending the shackles of the flesh, so he can live until now. In other words, he is actually a madman. Usually such people are safe. At least for Chen Yu.

So Chen Yu turned around and walked to the door, gently turned the door lock, and went straight in.

The guard room is quite big.

The guard room at the satellite launch center is at least a standard one-bedroom, one-living room room. The front is the living room, and the back is the rest area.

There was a bonfire in the middle of the living room. Zhang Yong was still alive.

He was wearing a tattered, ridiculously thick military coat, and he had no idea how many layers of clothes were stuffed inside, making him look bloated. And, he probably stank.

The whole room was filled with a sour and fetid smell.

But what surprised Chen Yu even more was that almost all the walls in this room were covered with mathematical formulas. . They were so densely packed that they looked like a heavenly book. Damn!

Who is this guy? A math teacher? A math teacher from a university?

When Zhang Yong saw Chen Yu coming in, he was stunned at first, as if he didn't recognize him.

He stared blankly for more than ten "zero three three" seconds, then he came to his senses and blurted out: "Mr. Chen? You're here again? Don't worry, I'm fine. I'm fine." "Are you... really fine?" Chen Yu looked at him in confusion. "I'm really fine."

"Teacher Zhang, what are you doing?"

Zhang Yong looked at the walls around him and smiled innocently: "Oh, I'm deriving some formulas." "Are you deriving these formulas because you're bored? Or you..." "No, I'm not bored."

Zhang Yong's expression immediately became serious, and he said in a serious tone: "Mr. Chen, I have seen a movie before. It was made abroad and it was about an old mathematician.

I have been arguing that there is an integer between 3 and 4. "

"I've seen it too."

Chen Yu nodded.

"It would be best if you've seen it. Really, that movie is real. There should be a positive integer between 3 and 4. Once you find this positive integer, you can find the portal between the three-dimensional world and the four-dimensional world."

"..."

Chen Yu was speechless.

But Zhang Yong seemed to be possessed. He stood there and began to explain the relationship between numbers to Chen Yu. He talked from one wall to another, from the ground to the ceiling. His eyes were shining as he explained.

Chen Yu believed, he really believed that there was a positive integer between 3 and 4. Moreover, he believed that he could deduce it. After listening for a long time, Chen Yu could not help but interrupt him and asked: "Teacher Zhang, wait a minute, I want to ask you, which university is your math teacher from?"

"Ah?" Zhang Yong was stunned.

"Let me ask you, which university do you teach at?" "I... I'm a village teacher." "What?" "Village teacher." Zhang Yong smiled awkwardly: "I teach in elementary school."

"..."

Zhang Yong saw Chen Yu's face full of black lines, and quickly explained: "Although I teach in elementary school, I am a college graduate. I graduated from the Department of Mathematics at Peking University."

"Oh."
