Zhao Huasheng remembered many people and many things. He remembered the couple he met that day, the old man who was the chef in the small restaurant, and every ordinary person he met on the street.

Zhao Huasheng's head began to suck again. Zhao Huasheng stood up and wanted to wipe away the tears from his face, but found that the tears had frozen on his face. Once wiped, the tears turned into ice slags and spilled down from his face.

"I'm sorry, I understand." Zhao Huasheng's voice became very hoarse.

"Warson, it's not your fault." Li Wei comforted softly: "No one would think of such a thing."

Zhao Huasheng glanced at Li Wei with gratitude and nodded at Li Wei.

The old man in the town sighed and directed several people to move Freia's family to the sled. A group of people slowly walked towards the town - in order to prevent the sled dogs from consuming a lot of calories and being frozen to death, they did not dare to let the sled dogs walk too fast. At the same time, they took off their clothes and put them on the sled dogs to help keep them warm.

The wind and snow all over the sky became smaller at some point, and the residents of the town finally returned to the town. The only pastor in the church put on a robe and began to pray for Freya's family. The welcome banquet that originally welcomed Zhao Huasheng and his group also turned into a funeral.

The atmosphere in the town began to become heavy and depressing. Zhao Huasheng locked himself in the room, and did not come out for three consecutive days except for eating and solving physiological needs. Zhao Huasheng seemed to be able to smell the scent of Freya's family from this house, hear their words and laughter, but he could not see them anymore, and he would never see them.

The subsequent supplies arrived one after another in these three days, and it was finally time to set off. Zhao Huasheng left his room and met with everyone. Several helicopters had already stopped in front of the town church. At this time, the residents of the town came here.

To the crowd who bid farewell to him, Zhao Huasheng said: "Don't stay in this town anymore, go to Equator City. Contact the government now. The government will send someone to pick you up. Don't stay here anymore. Don't you know? The weather has changed, and it is no longer suitable for human survival."

Zhao Huasheng cannot undermine the confidentiality regulations, and these words are all Zhao Huasheng can say.

The old man sighed tremblingly and said, "The weather is getting colder and colder, alas, we all know. But how can we leave here? We have lived here for a lifetime and spent a long time of seventy or eighty years. We just want to grow old quietly and die here. After leaving here, we don't know where to go. Young people like to run around and go. If they want to go to Equator City, they will go to Equator City. We are all old and can't walk anymore, so we stay here and don't go anywhere."

Zhao Huasheng seemed to hear what the restaurant owner, who was also old, said to him.

"Anyway, I haven't had a few years to live, so let's be here."

Zhao Huasheng could not understand the words and choices of these old people, but Zhao Huasheng knew what kind of deep feelings it was. Under the threat of death, this deep feelings made them choose to stay behind their hometown and refuse to leave. Zhao Huasheng was sure that there must be many elderly people around the world who have the same idea.

Even if they die, they will not leave.

If you don't leave, you will die.

And Zhao Huasheng didn't want them to die.

Zhao Huasheng felt a heat in his eyes, but Zhao Huasheng finally held back. Zhao Huasheng turned his head and said a little hoarsely: "Okay, then you guys stay here. Hope... I can have the ability to change all this before the weather is unacceptable."

The old people were a little confused. They didn't understand what Zhao Huasheng meant. But they still expressed their gratitude and blessings to Zhao Huasheng. Zhao Huasheng turned around and boarded the helicopter and never dared to look here again.

The helicopter took off in the huge roar and the snowflakes rolled up by the propeller, left here and flew quickly to the North Pole. There, the staff at the Arctic Changshan Station would stay for three more days.

The Arctic is very dangerous, especially after the solar radiation level has dropped significantly, the dangers and harsh environment of the Arctic are beyond the limits that people can imagine. But Zhao Huasheng still chose the Arctic goal. No one asked Zhao Huasheng why he did this - as long as Zhao Huasheng thinks it is necessary, even if Zhao Huasheng wants to go up to the moon, they will find a way to satisfy him.

In fact, even Zhao Huasheng himself didn't know why he was going to the North Pole. He just kept ringing in his heart, "Look at these scenery, they will disappear soon and will never be seen again."

The impact of the reduction in solar radiation level is global. Zhao Huasheng knew that from then on, the scenery such as flowers, birds singing and fragrance, and the gurgling streams will disappear one by one, and ice and wind and snow will be eternal.

Zhao Huasheng was commemorating all this, and Zhao Huasheng wanted to keep all these scenery in his heart before it finally disappeared. Perhaps only in this way can one overcome the decline and collapse on the scale in Zhao Huasheng's heart, perseverance and struggle and never giving up this place can one overcome the sinking and collapse. After all, Zhao Huasheng is just an ordinary person.

Zhao Huasheng and Li Wei sat side by side in their seats without saying a word. The huge roar of the helicopter sounded extremely monotonous at this moment, just like the scenery of the earth under the helicopter.

It was an endless white ice field. Sometimes you can see living creatures on this ice field, such as polar bears, Arctic foxes, or wolves or deer. When the helicopter flies by, they will raise their heads and observe this strange object, as if thinking about why this thing flies.

"We used to be worried that global warming caused by the greenhouse effect would melt Arctic glaciers and affect the ecosystem here. Now, we don't have to worry about this anymore." Li Wei said with her hands spread out. "If I remember correctly, there was no frozen here at this time last year."

"This is not funny." Zhao Huasheng shook his head.

"Don't always be so heavy." Li Wei said softly, "My brother has confidence in you, so he gave this task to you. Similarly, I have confidence in my brother. I believe that my brother's choice will not be wrong. You can definitely do it."

Zhao Huasheng sighed and looked at Meng Zhuo: "Did there be any new discoveries in the scientific research department in the past few days?"

"Yes," said Meng Zhuo, "Further observations show that the suspected Dyson sphere that appears in the solar photosphere is not a physical substance, but because the temperature drops, it appears darker and darker. At the same time, some observations show that it seems to appear above the solar troposphere, not the previously speculated photosphere. Of course, this requires more observational evidence to confirm."

The sun is divided into three cores from the inside out, with three parts: the radiation layer and the troposphere. Then outside is the atmosphere. The photosphere is the layer closest to the surface of the sun in the sun's atmosphere.

"Does this imply that the reduction in solar radiation levels is due to certain physical mechanisms within the sun?" Zhao Huasheng asked.

"The evaluation data of the scientific research department shows that this possibility has risen to 80%. The possibility of intentional interference of some external force, that is, the unknown civilization, has been reduced to less than 20%. The scientific research department has also suspected that the change in the sun was caused by an unknown advanced civilization, but it does not look like this now. It is more like the independent change of the sun. You are a scientist in stellar physics, and maybe you can also make your own speculation about this matter."

"I can't imagine any physical mechanism that may cause this phenomenon." Zhao Huasheng shook his head, "Has anyone in the scientific research department proposed a physical model?"

"There are two types. One is the theory of neutrino escape, and the other is the theory of thermonuclear fusion loss in extreme environments. Of course, this is just a hypothesis. The scientific research department is unable to find enough evidence to support these two statements at present."

"Oh?" Zhao Huasheng became a little interested, "Give me relevant information to show me."

Meng Zhuo nodded, and five minutes later he brought a stack of documents and handed them to Zhao Huasheng.

"Neutritious escape theory... Due to some unknown reason, a large number of neutrinos were generated during the fusion process of the core of the sun. Because the density of the core of the sun is too high, even neutrinos that are extremely difficult to react with matter cannot escape smoothly. A large number of neutrinos undertake the task of supporting the structure of the sun. Then, after leaving the core of the sunflower, the neutrinos began to escape freely and carried away a large amount of energy, which led to a decrease in the solar radiation level..."

Neutrinos are very magical particles that almost never react with any matter. They are also very small, so small that they can even pass through the entire earth freely without colliding with any particles that make up the earth. This hypothesis is to use neutrinos as the key to explain all changes. But this explanation also has a considerable loophole.

That is, is the density of the material of the sun really so large that even neutrinos cannot escape smoothly? At least based on the knowledge Zhao Huasheng has mastered at this moment, the density of the material of the sun is far beyond the reach. Moreover, if this hypothesis is true, then the neutrino telescope deployed deep underground on the earth should be able to capture neutrinos far beyond the previous level.

"Someone has proposed a new nuclear fusion model, predicting a completely new, different from the past neutrino particles to explain the contradictions in this hypothesis. The scientific research department is seizing the time to verify this hypothesis, and the results will come out soon." Meng Zhuo said.
