"What can I do?" Su Mei turned her head and asked back.

Actually, she doesn't know much about what she is doing now.

"Yes, being able to start the nuclear fusion device of Jinghai Laboratory in advance is the most useful thing we can do now, just like I used this reason to convince Teacher Sun." Lu Yuan nodded and confirmed.

"Since Jinghai Laboratory's equipment is already very mature, it not only refers to power generation, but also refers to the fact that it has been connected to the State Grid and can be connected to the grid to generate power." Lu Yuan reached out and clicked in front of him. The three-dimensional map of Huanglong Kingdom appeared in front of Su Mei, and the girl could clearly see their current location and the temperature and weather map.

"Look." Lu Yuan explained to Su Mei according to the picture: "The current temperature in the northern region is around minus 5 degrees Celsius, and it may drop to minus 10 degrees Celsius in the middle of the night. Of course, it is very cold, but it is also a relatively adaptable weather."

Su Mei nodded. If you have minus ten degrees Celsius, you can handle it if you don’t go out frequently. When it’s cold, minus fifteen degrees Celsius are not unavailable.

"But the trouble now is that the snowfall will not stop in the short term. Even if it is light snow, when snow covers the earth, it will further affect the speed at which the earth absorbs sunlight, because a large amount of light and heat are perfectly reflected. We humans have been worried about global warming for so long, and now we will slowly understand that the ice world is what should be feared."

Seeing that Lu Yuan was a little off topic, Su Mei gently clenched Lu Yuan's finger: "Tell me the key point."

"The key point is to start today. The lowest temperature will drop by about three degrees Celsius for fifteen consecutive days. By the fifteenth day, the temperature here will drop to about minus 60 degrees Celsius. If we move north, the temperature may be even lower. The North Pole may even measure extreme climates such as minus 100 degrees Celsius." Lu Yuan said calmly: "After fifteen days, as the purple celestial phenomenon slowly ends, the earth will receive sunlight again, and the temperature will slowly rise. Although there will be some climate problems in the middle, compared with the low temperature of minus 60 degrees Celsius, it is nothing. The heating rate will drop a little faster than ours, and it will be able to return to normal weather in about ten days."

"So." Su Mei looked at Lu Yuan and concluded: "That is to say, the ground will experience an extremely low temperature of less than minus forty degrees Celsius that lasts about ten days?"

Su Mei concisely summarized Lu Yuan’s meaning, and Lu Yuan nodded with certainty.

"So what can the nuclear fusion device do?" Su Mei continued to ask.

"Power generation, electricity is the lifeline." Lu Yuan said: "Humans have sufficient experience in dealing with the cold. Whether it is heat-insulated houses, heavy clothes, including the fireplaces that make fires, everything, humans have accumulated a lot of experience in dealing with the severe cold."

"But the most effective response is to use electricity."

"Because the electricity is sufficient and cheap, you can get it as long as you have a thin wire, and you don't need to store coal or firewood, or even paper books for burning."

"But the electricity is not enough, right?" Su Mei asked.

Lu Yuan nodded in a sure place: "Yes, the problem is that there is not enough electricity."

"The power generation in the power grid is a very complex issue. Basically, its purpose is to use as much electricity as you want, and try not to waste resources."

"But if the temperature really drops, it's like the severe cold and heat, human electricity consumption will still surge. Even if nothing happens, the State Grid will be overwhelmed."

"What's more," the boy paused: "That's really happening this time."

"Because of the impact of the solar storm, although I prepared in advance, I checked and found that we still lost about 30% of the electricity supply."

As he said this, Lu Yuan tapped on the three-dimensional map in front of him, and the original temperature map instantly turned into a power-supply map. Su Mei could see a large red patch on it.

"Red means areas with insufficient power supply, and in such a severe cold, once the power supply in a certain place is cut off, it means that they will soon be frozen to death. This is even more terrifying than the Great Famine. After all, there will be at least a few days of buffering period when starving to death."

"But I didn't freeze to death." Lu Yuan said.

Lu Yuan has too much say about the fact that he will die soon after freezing, so he doesn't want to speak now.

Speaking of this, Su Mei really understood: "So, the electricity generated by Jinghai Laboratory now can fill this electricity gap and make the power supply that was originally ineffective is abundant, right?"

From this perspective, generating more electricity means saving more people.

Not fake at all.

"Of course, but it's not just that." Lu Yuan said confidently: "Although Susu, you don't know much about nuclear fusion, there is a common sense that you need to understand, that is, nuclear fusion reactions will produce massive waste heat. In normal times, these waste heats are very troublesome and difficult to deal with, which will form a heat island effect around the nuclear fusion power station. In the hot summer, it will even cause the surrounding temperature to rise above forty degrees Celsius, becoming a truly terrifying steamer."

"But now, these calories have become precious wealth?" Su Mei asked.

"Yes, precious wealth." Lu Yuan nodded.

In the cold, heat is of course the most precious wealth. In order to keep warm, humans can burn everything they can burn.

Then, in this world, the most combustible thing is nuclear fusion fuel.

"I originally considered the use of the nuclear fusion base of Jinghai Laboratory after the sun was extinguished. Although Yanjing City would establish an independent capital of the southern part of the world, the nuclear capabilities of Jinghai Laboratory should not be wasted. It is possible to establish a small satellite city above Jinghai Laboratory as a supplement to Yanjing, but now it is a coincidence."

Lu Yuan said: "Simply put, the nuclear fusion waste heat of Jinghai Laboratory was originally used as heating to transport it to the urban area of ​​Yanjing City as a supplement to heating. Now under the current situation, heating will become a more severe task, and the existence of Jinghai Laboratory is of great significance."

"Okay, okay, I understand." Su Mei nodded: "It's a kind of war that can determine the direction of the battlefield as soon as the recruits first came to the battlefield, right? Isn't it?"

"So." Su Mei hugged Lu Yuan's head and kissed him on the forehead.

"My Luyuan classmate."

"You need to have a good sleep."
