——For some reason, he never thought of leaving.

Life in the institute was not as orderly as in the base. They did not have fixed tasks and positions, but they had a spontaneous division of labor. The institute took him in, and he knew he had to give back. He wanted to work hard and do something, and the people in the institute welcomed him.

At first, he would go out and collect edible plant roots with the boy in a safer area. Later, his body could not bear the cold wind, so he could only stay in the base to help with planting or cooking. Later, he could not even support such work. Everyone in the institute believed that he had some unidentified disease - this was common. In this world, any disease could happen, and even the whole world was incurable.

That day, Polly came to see him. From that day on, Anzhe lived with Polly Jong in the white building on the west side of the main building. Although his body was gradually weakening, his mind was still clear enough to be a qualified assistant. There was also a silent Indian man as an assistant in Polly's laboratory. He was good at repairing various equipment. His name was Code.

This is a solemn laboratory, with machines everywhere, and monitors connected to the machines. The largest one is an optical cable that extends from the laboratory to the ground and connects to a device called "Simpson Cage" outside. The

main component of the Simpson Cage is a five-meter-high mechanical tower, which is like a smaller version of the two white towers at the center of the institute. The shape of the two white towers - Anzhe looked at them for a long time and confirmed that they have many similarities with the huge artificial magnetic poles in the base. He immediately thought that the Gao Institute was the original place where the artificial magnetic poles were developed.

The towers form a rectangle that is more than ten meters long and more than twenty meters wide. When the Simpson cage is activated, the entire cubic rectangular space they enclose will be filled with a burning red light similar to a high-frequency laser, like a scarlet sea of ​​fire. Everyone in the institute knows that they cannot walk into an open Simpson cage, otherwise they will die an ugly death.

From the laboratory manual, An Zhe learned that the "Simpson Cage" is the most cutting-edge masterpiece in the field of high-energy physics during the heyday of human science, and it directly contributed to the success of the creation of the magnetic pole.

"Until now, we still don't know what causes the generation of magnetism. Some speculate that it is due to the flow of molten iron in the liquid core of the Earth, and some believe that it is due to the rotation of the electric layer in the mantle, but there is no sufficient evidence. We don't know the cause of the generation of magnetism, so we can't know why it disappears. This is beyond the limits of our cognition. In this way, we can't reproduce the electromagnetic field unless we make a magnet as big as half a Earth ball." Polly explained to him: "But there is a law of physics that we know that magnetism is generated by electricity, and the movement of electric charges generates a magnetic field."

"One of the contributions of the Simpson cage is that it can present the fluctuating fields between elementary particles, thereby analyzing the way they interact with each other and reproducing some phenomena. So we got the inspiration to create artificial magnetic poles - you lack physical knowledge, so I can't explain it more deeply. Simply put, the two artificial magnetic poles emit pulse waves of special frequencies, causing the resonance of charged particles in the solar wind, just like we hold a loudspeaker and tell you, please go that way. So the resonance and movement of the particles generate a magnetic field, and the ball is protected."

An Zhe nodded. He understood, but only understood. His job did not require him to master advanced physical knowledge, he just needed to take care of the instrument.

Sometimes, Polly was calibrating the frequency of the Simpson cage outside, and another assistant followed him. Anzhe was the only one in the white building. He sat there, with the low night sky outside the window. The machine emitted a monotonous hum, and the spectrometer connected to the Simpson cage drew complex curves. It was unknown what it was recording.

Those curves were noisy, tangled together, and had no rules. For no reason, he thought of the chaotic and terrifying lines drawn on the paper by the Si Nan in the Garden of Eden. Closing his eyes, feeling the increasingly violent fluctuations of the nothingness, feeling the passing of life day by day, he would be afraid, but sometimes he felt that he was gradually approaching eternity.

When Polly came back, he began to analyze the chaotic curves. Anzhe picked up the kettle beside him and poured him a cup of hot water.

"What are you doing?" he finally asked.

"I want to find that thing." Polly said.

Looking at the screen, Anzhe asked: "...what is it?"

"The thing that caused this world to change."

"It must be everywhere. If it is in this world, it must also be in the Simpson Cage." He said.

An Zhe frowned slightly.

Polly picked up a compass at hand: "We can never see the magnetic field, but the direction of the compass can tell us that it exists. The same is true for other invisible things in the world. Our cognition is too shallow, and we can only pursue the appearances we project on the world."

"Look here." Polly highlighted a smooth curve: "Everything in the world is interacting, and there is a lot of information in the traces of interaction, like this line, like the compass, it represents the magnetic field."

"We assume that the changes that are happening in this world are because something huge is gradually coming... but the magnetic field can resist it to a certain extent. Since the magnetic field can resist it, it must have a similar way of presentation as the magnetic field." Polly's gray-blue eyes stared at the messy screen in fascination: "It is very grand and beyond our cognition. What has changed is the essence of this world, but it is here. I think there must be a specific receiving frequency that can see the shadow of it projected on the real world."

Anzhe asked: "Then what?"

Polly shook his head slowly: "We must first know what it is before we can think about how to deal with it."

But can we really find it?

Anzhe looked at the screen in confusion.

As if knowing what he was thinking, Polly opened his mouth.

"Although it's very slim, but..." He only said half of his words and sighed softly, "After all, we have created many masterpieces that are unimaginable to humans before."

Anzhe read the fluctuations in his tone and repeated his last sentence: "Masterpieces that are unimaginable to humans."

Then, he watched the little light shining in Polly's eyes gradually dim.

Polly Jones looked at the endless wilderness outside the window, the sky full of gray haze, and the howling of beasts from all directions. There were strange fluctuations in the sound, which could not be interpreted by the human voice spectrum.

"Only for humans." He whispered, "Before we were shattered, we thought we understood the whole picture of this world."

At that moment, An Zhe saw the loneliness that spanned eternity in his eyes.
