At first, he would go out to collect edible plants with the boy in a safe area. Later, his body couldn’t bear the cold wind and he could only stay at the base to help with planting or cooking. After that, he couldn’t even support such work. People at the institute thought he was suffering from an unidentifiable disease. This was a common thing. In this world, any disease could happen. Even the entire world was ill.

One day, Polly came to see him. From that day, An Zhe followed Polly Joan to a white building on the west side of the main building. Although his body was gradually weakening, his mind was still clear enough to be qualified as an assistant. There was also a silent Indian man working as an assistant in Polly’s laboratory. He was good at repairing various equipment.

This was a rigorous laboratory, filled with machines on all sides and displays connected to the machines. The largest one had an optical cable line that extended from the laboratory to the ground and was connected to a device called a ‘Simpson Cage’ outside.

The main components of the Simpson Cage were four mechanical towers that were five metres high, just like the scaled-down versions of the two white towers outside the institute. An Zhe watched them for a long time and confirmed there were many similarities with the huge artificial magnetic pole at the base. He immediately thought about how the Highland Research Institute was originally the place where the artificial magnetic poles were first developed.

The four towers formed a rectangle that was 10 metres long and 20 metres wide. Once the Simpson Cage was activated, the entire cubic rectangular space would be filled with a glowing red light similar to a high-frequency laser, like a scarlet sea of fire. Everyone at the institute knew that they couldn’t walk into the open Simpson Cage or they would die in an unsightly manner.

From the laboratory’s manual, An Zhe learned that the Simpson Cage was the most cutting-edge masterpiece in the field of high-energy physics at the height of human science and it directly contributed to the success of the artificial magnetic poles.

“Until now, we don’t know the cause of the geomagnetic field. Some people think it is due to the flow of molten iron in the Earth’s liquid core and others think it is due to the rotation of the electric layer in the mantle, but there is no strong enough evidence. We don’t know the reason why it is produced so it is impossible to know why it disappeared. This is beyond the limits of our cognition. Similarly, we can’t produce the electromagnetic field unless we create a magnet half the size of the Earth.” Polly explained to him. “Still, one of the physical laws we have is that magnetism is generated by electricity and the movement of the electric charges generates a magnetic field.”
