I Have a Mansion in the Post-apocalyptic World (Web Novel)

“Let me guess, you are Lin Yi?”

The girl shook her head. Her big, curious eyes blinked with innocence as she looked straight at Jiang Chen.

If she dyed her long luscious black hair silver and then put on some red contact lenses, then she would be no different than Lin Lin.

“Well… then you are?”

“No. 1004,” The girl quickly replied.

Not even a name? That’s simple.

Jiang Chen shook his head with a bitter smile. He rubbed her head to comfort her.

The girl felt the sympathy in his eyes, but she showed a confused expression to his sympathy. Clearly, she did not understand the reason for his sympathy, or that she did not think that being nameless was worthy of sympathy.

“Do you want a name?” Jiang Chen looked into her eyes.

The girl shook her head and then suddenly raised her head, as if she had received some kind of signal, and ran away.

Jiang Chen looked at the direction No.1004 ran to, then he stood up straight and looked at the newly built research institute in his backyard

Ten days ago, the institute was completed, and Lin Lin’s sisters had already moved in. Because she was very pleased with the design of the institute, Lin Lin took the largest laboratory as her own and then moved the experimental equipment piled up in her room there.

She finally made space in her bedroom.

To make it easier for Lin Lin, the construction party created a small door that could access the research institute from the mansion based on the request of Jiang Chen. Other than Lin Lin who used the door every day, her sisters occasionally slipped into the backyard of the mansion to stare at the flowers and plants.

As for why Jiang Chen was standing there, the story began two days ago.

…

The clock turned back to two days ago, May 4th.

Kelvin called from the ground command centre and reported some good news to him. The Stingray A-1 tasked with the UFO investigation successfully returned. It did not find signs of life on the flying object and brought back a sample.

Although the sample had not been delivered, the relevant data was transmitted to the ground command centre. However, many experts and scientists were puzzled by the fact that the density of the sample reached an astounding 2,985 grams per cubic centimeter.

Intuition told Jiang Chen that it was something incredible.

In fact, it was not even intuition. Hawking, who participated in the research project of extraterrestrial civilization, directly told him that this discovery was likely to completely change the perception of matter in modern physics. There was no single element that could form a substance with such high density while still being stable.

Since modern science could not explain it, Jiang Chen immediately sought help from the future.

After Kelvin organized all the data, Jiang Chen returned to the apocalypse. He tossed the USB stored with the highest class confidential information to Lin Lin.

After receiving the data, Lin Lin completely locked herself in her lab for two straight days. Seeing her serious attitude, Jiang Chen did not bother her. He decided to stay in the apocalypse during those two days and had been taking morning and evening walks in the backyard.

Just then, he saw Lin Lin at the door.

The little girl didn’t seem to have slept at all. She was yawning while walking toward him.

“I’m finally done… Wait, did you do something to my sister?” Lin Lin, who was still tired, suddenly woke up as if someone had just shocked her. She suspiciously looked at Jiang Chen.

“What could I have done? Am I a pervert…” Jiang Chen facepalmed.

Lin Lin answered this question with her eyes and said with vigilance, “I warn you, No.1004’s research is related to space theory. She is my assistant in transporting living things into interdimensional travel. You can’t give her strange thoughts.”

“Whatever. Don’t accuse me the moment you see me… So, did you figure out what the ball was?”

Lin Lin shook her head and sighed.

“2,985 grams per cubic centimeter, the density is 2,985 times that of water at room temperature. It’s far denser than the densest base metal, Osmium, with a density of 22.6 gram per cubic centimeter. Do you know what this means?”

“What does it mean?” Jiang Chen asked immediately.

“59 grams per cubic centimeter, which is the density of the red dwarf closest to the solar system, is not even close to the small ball you gave me. This means that the force between the particles in the ball is even more terrifying than the red dwarf’s own gravity. This force has transcended the scope of Van der Waals forces. If I am not mistaken, there is only one possibility left.”

“What possibility?” Jiang Chen was in a state of shock.

“Strong interaction force. That small ball is composed of countless hadrons and even quarks…” When she raised this hypothesis, Lin Lin revealed a strange expression. It looked like she was doubting her own hypothesis while being extremely convinced.

“Strong interaction force material? Is there any technology in the field before the war?” Jiang Chen asked.

Lin Lin looked at him like an idiot and glared at Jiang Chen. “How could there be such a thing. Until the war, there was a lot of controversy about the existence of strong interaction force materials. Did you really just ask if this technology existed?”

Jiang Chen had long been used to Lin Lin’s ridicule, and he didn’t want to argue with her, so he opened his hands and shrugged. With thick skin, he said, “I don’t understand this. That’s why I asked you. The smart Miss Lin Lin. Can you explain it to me? If the ball is a material made by strong interaction force, how advanced is it compared to pre-war technology?”

Lin Lin had no resistance to flattery. Her chin rose up proudly and she patiently explained to Jiang Chen.

“The so-called strong interaction force refers to the force acting between hadrons. The strong interaction force holds the most ordinary matter together because it confines quarks into hadron particles such as the proton and neutron. As the strongest force in the four fundamental interactions, its range of action is only at the range of 10 to the minus 15 meters. Exceeding this range, the strong interaction force will decay exponentially.”

“If the particles in the material are composed of strong interaction forces, it means that the spacing between the particles must be within 10 to the minus 15 square meters unless the atoms are forcibly removed and all electrons are discarded. However, this creates another problem. A strong interaction material that completely discards electrons will carry a very large positive charge, attracting a large number of electrons, which in turn destroys its particle structure.”

From the perspective of modern physics, this material shouldn’t exist.

As for the future.

Who knows about the future?

The development of science itself was a process of constant imagination, constant application, and constant self-denial.

As for the civilization that has mastered the strong interaction force material, Lin Lin couldn’t answer as to how advanced they were. It was not something that could be judged by time.

However, Lin Lin was sure about one point. That is, from the understanding of particle physics alone, the gap between the two civilizations was insurmountable.
