Arctic Circle.

Lu Zhou was testing a stone in a scientific research laboratory at this time. If Chu Zixuan was here, he would recognize it at a glance. This stone looked very similar to the one he saw in Tianshi Village!

He is still quite satisfied with the fact that physicists, biologists, historians and chemists are all gathered here at the moment. In the past, humans were not so united. If they want to do a joint research, they must consider the pros and cons for themselves...

Soon, experts from various disciplines tested the stone in turn through their own fields.

After their inspection was over, Lu Zhou quickly asked, "How is it, what is this?"

Archaeologists first said: "Judging from the stratigraphic structure, this stone first appeared on Earth, a million years ago..."

Other scholars expressed their agreement, "According to the detection, this thing has indeed been on Earth for a million years!"

Lu Zhou frowned and said, "You mean, this stone is not a product of the earth?"

"That's right!"

An astronomical expert nodded and replied: "This is a fragment left by an asteroid about one kilometer in diameter when it hits the earth, not a product of the earth!"

"We used a variety of algorithms to roughly estimate that the meteorite existed for 100 million years, but it only reached the earth for one million years!"

Lu Zhou nodded and said, "I understand, that is to say, there are about one kilometer in diameter, now, I don't ask you to understand the reason why this stone can shield insects. I want you to calculate the impact point when this asteroid hit the earth a million years ago, as well as the sputtering range and possible dropping location after the impact!"

As soon as the words were finished, an expert reported: "The impact point has been simulated. When others calculated, I had simulated the impact point!"

As he said that, he quickly handed the simulated image to Lu Zhou to watch.

Lu Zhou took it over and saw that, sure enough, a video of an asteroid crashing into the earth from outer space and then colliding on his tablet. He said in a deep voice: "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 according to the geographical location of a million years ago. The mainland at that time was different from now..."

"You just talk about your current geographical location!"

"Shuchuan!"

Lu Zhou was stunned and said dumbly: "Don't tell me that the Shuchuan Basin was knocked out by this asteroid."

"It is not entirely due to the asteroids. The formation of the Shuchuan Basin was gradually formed due to the movement of the earth's crust. We can only simulate the specific landforms of millions of years ago by the differences in the stratigraphic soil..."

After some sorting, Lu Zhou understood everything, and then threw a sentence to continue studying why this stone could block the insects, and then ran towards the command center quickly.

...

Arctic Circle-China Command Center.

After Yao Zhenguo received the news, he was very surprised and said quickly: "Are you saying that such a small stone can isolate insects?"

Lu Zhou nodded and said, "That's right, although I don't know what the specific principle is, all types of insects will take a detour when they encounter such stones..."

Yao Zhenguo quickly asked again: "Then how big is the coverage of this kind of stone?"

"According to research, we tentatively stipulate that this stone is based on mass to affect the radiation range..."

Lu Zhou took out a piece of paper seriously and said while calculating: "For your understanding, I will use the content that does not exceed compulsory education..."

Yao Zhenguo heard that he had no expression after hearing this. He had forgotten all the formulas he had learned over the years. He wanted to say something, just say the conclusion, but seeing Lu Zhou's excited look, he still did not interrupt.

"After professional calculations, we learned that the density of this stone is 3g/cm3, mass is about 100g, volume is 33cm3, and the radiation range is roughly a circle with a diameter of 100 meters..."

Yao Zhenguo nodded, "In other words, such a small piece of 100 grams of stone can radiate the size of a diameter range of 100 meters?"

"right!"

"Then, how many stones are there in total?"

"We roughly calculated based on the diameter of the meteorite as one kilometer, and we concluded that the volume of this asteroid is about 294524306.25 cubic meters and the mass is about 883572.92 kilograms!"

"If all the meteorites are collected and spread out, they can cover about 613,442.96 square kilometers!"

Yao Zhenguo's eyes lit up and he asked quickly: "Where are there other stones besides Shuchuan?"

"There are basically all over the country. One is that the sputtering range is wide enough, and the other is that the movement of the earth's crust brings these stones to all parts of the country!"

"However, the closer we are to the Shuchuan Basin, the greater the number and division density of stones!"

While telling the story, Lu Zhou opened the satellite map information and pointed to the situation on Shuchuan and said: "Look, in this Shuchuan area, there have been found that there are hundreds of places without insects at all..."

"In addition, there are some peaks that have similar conditions, which means that there are those kinds of foreign meteorites in these places!"

“Beautiful job!”

Yao Zhenguo praised him with a rare word and asked: "What is the name of this stone?"

Lu Zhou was stunned and said, "It's not time to name it!"

After learning about the specificity of this stone, their research institute did not stop and started experimenting for a moment, so there was no time to think of any name.

"Then you name one now!"

Lu Zhou knew that the matter was urgent, so he was not pretentious. After thinking about it, he spoke, "Just call Dawn Stone, drive out the darkness and welcome the dawn!"

"good!"

Yao Zhenguo clapped his hands and confirmed it. At the same time, he quickly issued an order to his subordinates: "Integrate all the information sent by Lu Zhou and send it to various military regions across the country to let them know the existence of the Dawn Stone. In addition, close military regions can consider taking civilians to the Shuchuan Basin..."

Soon, above the Arctic Circle base, dozens or hundreds of Chinese planes took off again and flew towards the Chinese territory. This time, they went with dawn!

...

After Lu Zhou left, a member of the think tank asked in confusion.

"Do you need to inform other countries of this information?"

Yao Zhenguo asked back: "Does there be dawn stones in other countries?"

The think tank member shook his head, "No, the dawn stone is almost all in our country!"

Yao Zhenguo said calmly: "Then let it slow down first!"

...

When Lu Zhou returned to the scientific research institute, someone came up to report quickly.

"It has been confirmed and calculated through satellite comparison. In addition to being attached to the rocks, a large number of Dawn Stones have been buried deep underground due to the movement of the earth's crust..."

"According to the crust motion map of the past million years, the more underground the Shuchuan Basin, the more dawn stones there are, the more dawn stones gathered on the mountains higher than the west of Shuchuan..."

"Have you found the detection method?"

"No, we can only determine this stone based on the insect's fear of the Dawn Stone and dare not approach it... The Dawn Stone looks too ordinary. If it weren't for the characteristics of expelling the insect, its various attributes were almost the same as ordinary stones..."
