In the shot, everyone only saw a black field of vision, and only the stone pillars formed by stalactites could be seen in the places where the tactical flashlight had been illuminated.

These stalactites don't know how many thousands of years they have grown, and they are connected to the bottom of the cave from the top, and their whole body is white, like jade pillars on the palace.

"Everything works."

"According to the tester, the altitude here is -723 meters, the temperature is 24 degrees, the humidity is 70%, the atmospheric pressure is 105.7kpa, and no carbon dioxide siltation has been found, so there should be a vent here."

On the other side of the radio, the team's situation was constantly reported.

More than 700 meters underground?

Chen Chen nodded secretly, more than 700 meters deep is beyond the maximum range that some simple exploration methods can detect, that is to say, if a secret base is built in this cave, it is difficult to detect it with ordinary exploration techniques, unless large-scale joint exploration technologies such as gravity, magnetism, and electricity are used.

But on his own turf, how could Chen Chen allow others to do that?

"Found membranous foot stiff limb Ma Lu...... There are traces of life! ”

Suddenly, one of the team members looked down, and the flashlight shone on a crawling worm.

This long worm has hundreds of pairs of gastropods, and its body is black and white, and as it moves forward, hundreds of pairs of gastropods wriggle like waves.

But before the team member could reach out to catch it, suddenly a black shadow like a lizard flashed by, and quickly took the horse away!

"Wow!"

The team member was taken aback.

"What's going on?" Immediately, the team member asked.

"It's okay, it's a false alarm, it's just a salamander." The team member turned the flashlight over, and sure enough, he saw a palm-sized salamander landing on Ma Lu and quickly disappearing into the darkness.

"I hear the sound of water, there's an underground river."

"See, there's a pool of water ahead, it's deep groundwater!"

"There are traces of blind fish in the water!"

Hearing everyone's reports one after another, Brando suddenly asked, "Can you estimate the shape and size of this cave?" ”

"According to laser ranging, the length of the underground space is about 500 meters, and the width is 300 meters, which is a completely flat space, and the rock structure should be composed of two sets of rock systems, sedimentary rock and volcanic rock, and the sedimentary rock belongs to marine clastic rock and carbonate sediment."

On the other end of the radio, Thomson, who was in charge of geological issues, explained, "In addition to this, there is a waterhole in the center of the cave, there is the sound of living water flowing, it should be an underground river, there are fish living in the water, it can be determined that it is fresh water, it should be isolated from the underground rock formation, and there is no seawater backflow." ”

"What about the height of the inner cave?" Brando asked again.

"At the lowest point, about twenty meters, and at the highest point, about fifty meters, it is a perfect hemispherical space."

Hearing this, the entire team members on the yacht high-fived each other in celebration.

That makes it a perfect secret base.

"Wait until the rocks and water are sampled, and then come out."

Chen Chen on the side reminded, "After all, the microbial environment inside has not been tested, just in case." ”

"Yes." Brando nodded, "Everyone is on order, and after exploring the entire cave and collecting rock and dirt samples, you can exit." ”

……

In the afternoon of the same day, Chen Chen got a complete material report.

"This latitude and longitude ......"

Chen Chen looked at the report on the paper and rubbed his chin slightly, "Can you be sure that this is the location?" ”

"Yes, it's already been positioned."

Qian Wenhuan stood in front of Chen Chen's desk, "It's just southwest of the research center, which happens to be a plain, only about 2 kilometers away from the coastline. ”

"Good." Chen Chen threw the map on the table, "Zoning that area as a residential area, contact the Zhongzhou construction team in Namibia, and I will build a high-rise community here." ”

"Community?" Qian Wenhuan was taken aback, almost thinking that he had heard it wrong.

"That's right, it's the same community as the high-rise residents in Zhongzhou District."

Chen Chen nodded, "Not only that, but I also want to build corresponding commercial streets, parks, hospitals, and even transportation facilities in the surrounding area." ”

"Do you want to build a city?" Qian Wenhuan was dumbfounded.

"Otherwise, how can it be called 'Life Science City'?"

Chen Chen explained, "Although the welfare system of our research center is okay, if you want those researchers to have a sense of belonging, the allocation of housing is still very important. ”

After thinking about it, Chen Chen added, "The community is just one of them, I will also set aside a large number of villas by the sea for senior researchers to live in, when the employees have a home, they will naturally need entertainment facilities and living facilities, otherwise even if the house is big, it is still just a staff dormitory." ”

"What's more, after a large number of recuperation centers are built, those customers from all over the world also need to spend here."

"What you're talking about......" Qian Wenhuan wiped the sweat from his forehead.

"Wen Huan, you are the number one here, and it will be up to you to manage it after I leave,"

Chen Chen pointed to his head, "In the future, you have to move a little faster here." ”

"Boss, you—you're leaving?" Qian Wenhuan suddenly panicked, "How can I handle these ...... alone?"

"Don't worry, it's only temporary." Chen Chen leaned behind him, "I'll go back to Zhongzhou after a while, by the way, Wen Huan, you haven't been home for half a year, so I'll go back first when I have time recently." ”

"It's not like our company is in the development period, if I want to go back, I will definitely tell you."

Qian Wenhuan scratched his head embarrassedly, "By the way, I think if you want to develop that underground space, you can do it at the same time as the construction of the Life Science City, which is easier to hide from people." ”

"That's for sure."

Chen Chen nodded, "But the passage on the bottom of the sea is too troublesome, and another passage must be opened, and when the engineering team arrives, the foundation of the community will be laid first, and then the underground space will be opened in the name of drilling wells." ”

Hearing Chen Chen's order, Qian Wenhuan hurriedly took out the notebook in his pocket and recorded it.

After thinking about it, Chen Chen reminded again, "But be prepared, after all, the well more than 700 meters deep is a bit deep, and you must drill through the rock layer, the general drilling machine is useless, and you must use a large drilling rig." ”

"But if you use a large drilling rig, won't it be too eye-catching?" Qian Wenhuan's movements in his hands paused, and he hesitated.

"No, that's what wells are going to be done here in Africa."

Chen Chen waved his hand, "Take the location of the underground space as the center of the circle, first plan a town of two or three square kilometers, and then dig four or five wells, and wait until the underground space is drilled to buy off the workers who drill the wells, and at the same time restrict their movement and communication, and wait until they finish building the underground, and then erase their memories." ”

"With the engineering cover of the Life Science City, we can easily transport the materials needed for the secret base into it, and it is difficult for even Namibian officials to detect anomalies."

Qian Wenhuan nodded.

Chen Chen is responsible for setting the general policy, and the specific implementation is definitely his job.

After Qian Wenhuan left, Chen Chen looked at a missed call on his mobile phone and a text message sent and fell into deep thought.

The calls and text messages were sent by Wang Wei, who told him in the text messages that Professor Wang Xi had taken a long-term vacation during this time, and based on his recent performance in class, it should be a symptom of mild Alzheimer's disease......
