at the same time.

Bai Zhen and Wang Ning were sitting in the living room, flipping through information. The paper materials Zhao Bowen brought back could fill one suitcase, and the electronic files he brought back could fill another suitcase. This afternoon, Zhao Bowen put the colorful folders

When they were stacked one by one to exceed the height of everyone present, Lao Bai and Lao Wang thought that this guy had just robbed the print shop downstairs. However, Zhao Bowen turned around and took out the solid state drive from the suitcase, one by one.

Only the ground was higher than everyone else. It seemed that this guy had also looted Bainaohui. Old Zhao patted the folders and hard drives on the coffee table and told everyone that this was all the work we had done in the past half month.

It was hard for both of them to imagine that Zhao Bowen had completed such a huge amount of work in just half a month, and they were amazed as they watched.

"The F2 layer of the high-altitude ionosphere in Nanjing... balloon-suspended radar reflection experiment..."

"Full-band wide-area monitoring records of electromagnetic signals in East China from September to December."

"Monitoring records of sunspot activity and changes in the Earth's magnetic field from September to December."

"Cosmic Microwave Background Radiation Atlas... What is this? CERN? European Organization for Nulear?" Bai Zhen frowned, a stack of paper in his hand was all in English, and he could understand a Nulear, "Nuclear weapons? Good guys, you guys

And got nuclear weapons?”

"CERN, the European Center for Nuclear Research." Fan Jiangshu, who was sitting opposite Bai Zhen, explained, "It does high-energy physics research, not nuclear weapons."

"Have you never seen the high-energy particle accelerator and the Large Hadron Collider in the news?" Wang Ning showed his extensive knowledge and at the same time despised Lao Bai's ignorance.

"Europe? Have you found Europe yet?" Bai Zhen asked.

"To be on the safe side, I asked CERN for a copy of past experimental records." River Rat replied.

Bai Zhen put down the materials in his hand and said, "Awesome, you guys have done a lot in the past half month."

When the five people heard this, they all felt a little embarrassed at the same time, as if they were feeling uncomfortable. They all turned their heads and glanced at Bai Yang's room, then turned to Jiangshu and said in a low voice: "Isn't it because there is an iron hand chasing life?"

"Chasing life with iron hands?"

Bai Zhen and Wang Ning were stunned.

"Old Zhao?"

Fanjiang Shu nodded: "Teacher Zhao."

"Why is it called Iron Hand?" Bai Zhen asked.

"Because he always asks people to applaud." Che Gopher looked helpless, "If it weren't for Iron Hand, he wouldn't be able to handle it."

"Why is it called chasing life?"

"If you have a chance, see how he looks when he urges you to work." The pangolin sitting on the same sofa was still frightened. He hesitated, "The donkeys in the production team don't work like this either."

Bai Zhen opened another thick black folder, and on the first page there was an eye-catching red seal "Top Secret".

"Crack!" He closed the folder again.

"This... can we watch for free?" Bai Zhen raised his head and asked them.

"You can read whatever you want." Che Gopher nodded, "You can read all the documents brought here. They are also what you need to know."

Bai Zhen took a deep breath and opened the folder solemnly. Since he took the college entrance examination when he was twenty years old, Bai Zhen has never been exposed to such a highly confidential document.

At this moment he felt that he was an important person.

Inside the folder was a project plan, a thick book, roughly estimated to have more than a hundred pages.

"China Construction Eighth Engineering Bureau Co., Ltd."

"Purple Mountain Observatory of the Chinese Academy of Sciences."

"Rock Mechanics Laboratory of the Petrophysics and Reservoir Geomechanics Discipline Group, Institute of Geology and Geophysics, Chinese Academy of Sciences."

"That name is really long." Bai Zhen muttered in a low voice, "Nanjing Deep Earth Rock Mechanics Science Project... Rock Mechanics? Is that civil engineering?"

Wang Ning also came over to take a look curiously.

The two of them flipped through page after page and took a quick look at the flowers. They roughly understood what this plan was for. It was a scientific project to study the impact of human engineering on the deep underground geotechnical structure of Nanjing. It was sponsored by the Purple Mountain Observatory of the Chinese Academy of Sciences and the Chinese Academy of Sciences.

Jointly planned by the Institute of Geology, China Construction Eighth Engineering Group Co., Ltd. is responsible for the construction. According to the plan in the project project document, they will dig a deep pit underground in Nanjing and install a small unmanned laboratory to measure the stress of rock formations.

force situation.

But Bai Zhen didn't understand why he wanted to show this thing to himself. He was not engaged in geology or civil engineering. Why did the scientific research project on geology and rock soil mechanics get mixed up with the Days of Future Past and Save the World Amateur Radio Emergency Communications Command?

"This is another time capsule." Che Gopher said, "Super time capsule."

Bai Zhen and Wang Ning were surprised.

"In the past half month, we have been studying the method of slowing down time. We have previously confirmed that the distance is far enough to escape the large filter, but the method of putting the time capsule into space is too limited and the cost is too high.

High, and the preparation period is long, limited by rocket capacity, so we are actively researching other effective methods." Che Goshu continued, "Chief Wang, your previous experiment inspired us. You used the time capsule to

Cement was poured into the wall."

"To be precise, it's the community gate."

Wang Ning pouted, the time capsule was still at the gate of Meihua Villa Community.

"This proves that in addition to sending the time capsule into space, giving it strong enough protection and fixation can also allow it to successfully survive until the end of the world." Fan Jiangshu said.

"Is this also a means to weaken the purpose?" Bai Zhen asked.

"This can also weaken the purpose." Fanjiangshu nodded, "We bury it deep underground and seal it at the same time. There is no doubt that it is essentially the same as being sent to the orbit of Mars."

"Then what are you sending over this time?" Bai Zhen asked.

"It's a black box." Zhao Bowen's voice suddenly sounded.

Everyone turned their heads and saw Zhao Bowen leaning against the door frame of Baiyang's room with his hands folded.

"What we are sending here this time is a black box." Zhao Bowen came over and said, "Do you know about black boxes? Every civil aviation aircraft will carry a black box. It is a recorder with a solid shell that records the passenger aircraft in a loop.

Internal call records, if a flight encounters an air crash, the black box is the most direct and clear evidence, allowing people to analyze the cause of the disaster. What we want to send to the future is such a black box, which can tell us what will happen in the future.

"

"A tape recorder?" Wang Ning asked.

"A robot," Zhao Bowen said, "an AI system that will experience everything in the next twenty years on our behalf, and then tell us what exactly happened."

"It's unimaginable." Bai Zhen said.

He sketched a small robot like WALL-E in his mind. When disaster struck, the small robot would find a place to hide and hide it for twenty years until BG4MSR found it.

"It's not as complicated as you think. Our era itself is a world with highly developed information technology. Huge data flows are transmitted between everyone's mobile phones every day. No matter what happens, it will be reported on the Internet immediately.

Messages, so the black box does not need to actively search for information. It only needs to listen and hide in the deep underground to listen to the movements of the world. It has a set of keyword capture and filtering systems. Once suspicious information is found, it will capture and store it.

"Get up." Zhao Bowen said, "This technology is actually very mature. Government departments use this method to monitor public opinion. We will just copy it."

"Then you have to ensure its safety." Bai Zhen said, "make sure it survives these twenty years and can still work normally after the end."

"This is the hardest thing to do. We can't launch it into space, so the safest place is underground." Zhao Bowen nodded, "Dig a deep pit and bury it."

"Isn't this thing bigger than a time capsule?" Bai Zhen asked, "From your description, it requires at least a server room, data transmission lines, power supply system and cooling system... Such a huge set of things

, you want to dig a deep hole and bury them? Then you have to dig a very deep and big hole and then lift everything down. The amount of work is terrifying."

"We borrow what's already available."

"off the shelf?"

Zhao Bowen pointed to his feet, "Under our feet, underground in this city, there is a huge tunnel system extending in all directions."

Bai Zhen and Wang Ning suddenly understood.

Yes, there is a developed tunnel system underground in this city, and thousands of people flow underground every day.

subway.

"We comprehensively inspected the subway system in Nanjing, considered all factors, and finally selected two locations." Zhao Bowen spread out the map on the coffee table, took out a marker and drew two circles, one in Gulou Park and one in Gulou Park.

In Mochou Lake, "Below the office building of the Purple Mountain Observatory of the Chinese Academy of Sciences is Line 4, and next to Mochou Lake is the Mochou Lake Station of Line 3."

Like most underground laboratories in the world, Zhao Bowen uses the method of digging tunnels and then branching out. Jinping Mountain in Sichuan has the world's deepest dark matter laboratory. It is a space that branches out from tunnels that traverse the mountain.

, the top of the head is covered with 2,600 meters of mountain rocks, and Nanjing Metro Line 3 has the deepest subway station in Jiangsu Province, Mochou Lake Station. Zhao Bowen dug a small tunnel horizontally from the tunnel of Line 3, and the top of the head

Above is thirty meters of soil and rock.

"We dug a secret room under Zitai and a secret room next to Mochou Lake Station. The two serve as backups for each other. All equipment can be transported in from the subway station and placed in the secret room. After everything is arranged, we can move the subway

The entrance in the tunnel is sealed." Zhao Bowen said, "In this way, you only need to dig a small passage from the ground, which can accommodate one person to pass through, and the engineering workload is reduced by at least 80%."

“What about the power system?”

"Nuclear battery." Zhao Bowen said without thinking, "Multiple nuclear batteries connected in series can generate electricity and can be used for more than 25 years."

"Where's the heat dissipation?"

"There is a lake next to Mochou Lake Station, and we have designed a water-cooling channel." Zhao Bowen replied, "The secret room under Zitai is shallower and can be ventilated."

This guy has taken everything into consideration.

How much have they done in just half a month?

"We have four groups working on it at the same time, and Teacher Zhao is the second person in charge of the entire project," said Fan Jiangshu.

"I said I would bring thousands of troops."

Zhao Bowen looked down upon the audience: Am I awesome?

Bai Zhen: Awesome!

Wang Ning: Awesome!

Zhao Bowen: Applause!

The audience applauded warmly.

"The entire project is externally described as a geotechnical science project, but its actual purpose is absolutely confidential. The purpose of digging holes on the surface is to install rock formation stress detection devices, but in fact it is to bury the data recording system." Zhao

The blog post continued, “Once this system is sealed, only one person in the world can open it.”

"BG4MSR." Bai Zhen said.

"Among all of us, you are the best to her, Lao Wang." Wang Ning said, "Gifts are given one after another. They go up to the nine heavens to catch the moon, and down to the five oceans to catch turtles."

"When will this project start?" Bai Zhen asked.
Chapter completed!
