Arctic Circle.
Lu Zhou was currently testing a stone in a scientific research laboratory. If Chu Zixuan were here, he would recognize it at a glance. This stone is very similar to the one he saw in Tianshi Village!
He is quite satisfied now. Physicists, biologists, historians, and chemists are all gathered here. In the past, human beings were not so united. If they wanted to jointly conduct research, they had to consider the consequences for themselves. Pros and cons…
Soon, experts from various disciplines tested the stone one by one using methods in their respective fields.
After their inspection was completed, Lu Zhou quickly asked: "How is it? What is this?"
The archaeologist was the first to speak: "Judging from the stratigraphic structure, this stone first appeared on the earth one million years ago..."
Other scholars agreed, "According to the test, this thing has been on the earth for a million years!"
Lu Zhou frowned and said, "Are you saying that this stone is not a product of the earth?"
"That's right!"
An astronomy expert nodded and replied: "This is a fragment left behind when an asteroid with a diameter of about one kilometer hit the earth. It is not a product of the earth!"
"We used a variety of algorithms to roughly estimate that this meteorite has a history of 100 million years, but it only arrived on Earth one million years ago!"
Lu Zhou nodded and said: "I understand. In other words, a stone like this is about one kilometer in diameter. Now, I don't ask you to understand why this stone can shield insects. I want you to do it as soon as possible. Within a period of time, the impact point of this asteroid when it hit the earth one million years ago was calculated, as well as the sputtering range and possible fall location after the impact! "
As soon as he finished speaking, experts reported: "The impact point has been simulated. I have already simulated the impact point when others were measuring it!"
With that said, he quickly handed the simulated image to Lu Zhou for viewing.
Lu Zhou took it and took a look. Sure enough, the tablet showed a video of an asteroid falling into the earth from outer space and then colliding. He said attentively: "Where is this?"
He was stunned for a moment and found that the location of the impact point was different from the continent he knew.
"I simulated it based on the geographical location a million years ago. The continent at that time was different from now... "
"Just tell me your current location!"
"Sichuan!"
Lu Zhou was stunned and said dullly: "Don't tell me that the Shuchuan Basin was knocked out by this asteroid."
"It's not all due to asteroids. The formation of the Sichuan Basin was gradually formed due to crustal movement. We can only simulate the specific landforms millions of years ago through the differences in strata and soils..."
After sorting it out, Lu Zhou understood everything. After saying that he would continue to study why this stone can shield bugs, he quickly ran towards the headquarters.
…
Arctic Circle-China Command Center.
After Yao Zhenguo got the news, he was very surprised and said quickly: "You mean such a small stone can isolate insects?"
Lu Zhou nodded and said, "That's right. Although I don't know the specific principle, currently all types of insects will take a detour when encountering such a stone..."
Yao Zhenguo quickly asked: "What is the coverage area of this kind of stone?"
"Based on research, we tentatively determine that this stone affects the radiation range based on mass..."
Lu Zhou solemnly took out a piece of paper and made calculations while saying, "To facilitate your understanding, I will explain it using content that does not exceed compulsory education..."
Yao Zhenguo was expressionless after hearing this. He had long forgotten all the formulas he had learned over the years. He wanted to say, just say the conclusion, but seeing Lu Zhou's interest, he still did not interrupt.
"After professional calculations, we learned that the density of this stone is 3g/cm, the mass is about 100g, the volume is 33cm, and the radiation range is roughly a circle with a diameter of one hundred meters..."
Yao Zhenguo nodded, "In other words, such a small piece of 100-gram stone can radiate a diameter of one hundred meters?"
"right!"
"How many of these stones are there in total?"
"We roughly calculated the diameter of the meteorite as one kilometer and found that the volume of this asteroid is approximately 294524306.25 cubic meters and the mass is approximately 883572.92 kilograms!"
"If all the meteorites were collected and spread out, they would cover approximately 613,442.96 square kilometers!"
Yao Zhenguo's eyes lit up and he quickly asked: "Besides Sichuan, where else can there be such a stone?"
"They are basically found all over the country. One is that the sputtering range is wide enough, and the other is that crustal movement has brought these stones to all parts of the country!"
"However, the closer you are to the Sichuan Basin, the greater the number and density of the stones!"
As Lu Zhou narrated, he opened the satellite map data and pointed at the situation on the Sichuan River: "Look, in this Sichuan River, hundreds of places have been found to be completely free of insect infestations..."
"In addition, there are some mountain peaks with similar conditions, which shows that there are foreign meteorites in these places!"
"Well done!"
Yao Zhenguo gave a rare compliment and asked, "What is the name of this stone?"
Lu Zhou was stunned and said, "I haven't had time to name it yet!"
After learning about the special nature of this stone, their scientific research institute started experiments without stopping for a moment, and they had no time to think of a name.
"Then you name one now!"
Lu Zhou knew that the matter was urgent, so he didn't pretend to be pretentious. He thought for a while and said, "Call it the Dawn Stone. It drives away the darkness and welcomes the dawn!"
"good!"
Yao Zhenguo clapped his hands and confirmed, and at the same time, he quickly issued an order to his messenger: "Integrate all the information sent by Lu Zhou and send it to various military districts across the country to let them know the existence of the Dawn Stone. In addition, Li De If you want to reach the nearby military area, you can consider evacuating the civilians to the Sichuan Basin... "
Soon, in the sky above the Arctic Circle base, dozens or hundreds of Chinese planes took off again, flying towards the territory of China. This time, they went with the dawn!
…
After Lu Zhou left, a think tank member also asked in confusion.
"Should this information be reported to other countries?"
Yao Zhenguo asked: "Are there Dawn Stones in other countries?"
The think tank members shook their heads, "No, the Dawn Stones are almost all in our country!"
Yao Zhenguo said calmly: "Then take it easy first!"
…
When Lu Zhou returned to the scientific research institute, someone quickly came up to report.
"It has been confirmed and calculated through satellite comparison that in addition to the Dawn Stone attached to the rocks, a large amount of Dawn Stone has been buried deep underground due to the movement of the earth's crust..."
"According to the crustal movement map of the past million years, it can be inferred that the farther underground in the Shuchuan Basin, the more dawn stones there are. Similarly, the higher the mountains to the west of Shuchuan River, the more dawn stones are accumulated..."
"Have you found the detection method?"
"No, this kind of stone can only be determined based on the fact that bugs are afraid of the Dawn Stone and dare not approach it... The Dawn Stone is really ordinary. If it weren't for its ability to repel bugs, its attributes in all aspects would be almost the same as those of ordinary stones..."
