The door handle of the white door was a simple L shape. Xiao Liping stood on tiptoes and straightened his arms. He found that he was still at least ten meters away from the high door handle. He tried to push the door leaf. He shook his head: "This doesn't look like it is for humans. Designed doors. Take some photos. Let's move on. There are already two doors. There will probably be more. Don't forget to add location information to the photos."
While reciting the 400-byte true name of the African indigenous gods, Matrill took pictures with the camera on his shoulder. The two walked forward along the wall for a while. Sure enough, they found another door. "... Mom, God..." The little black man took a deep breath, took out a bottle of wine and poured some wine. "This is more like the devil's door..."
The door was black. The door frame was in a strange diamond shape. "XT9" was written on the door. Xiao Liping walked up to it and slowly squatted down, looking down at the strange door. He estimated the height of the door. It is about 40 centimeters and only 25 centimeters wide. It cannot allow adults to pass through. Only newborn babies can crawl by. Xiao Liping took the handle the size of a marble with two fingers and twisted it gently. The door opened. A black passage appeared behind the door. Lao Xiao lay down and used his headlight to illuminate it. He found that the road like a ventilation duct turned a corner not far ahead. He could not see where it led.
"It's just a prank room." Secretary Xiao stood up, patted the non-existent dust on his knees, and said to himself. He led Matilil to move forward. This time he arrived at the room not long after leaving. Turning the corner, they turned to the right and walked against the wall. More doors appeared in view. The two people kept taking pictures and marking. They found that this spacious cubic room was empty except for these mysterious doors. Neither There are creatures in the dark. There are no clues that can point out the identity of the builder. All visible surfaces are covered with smooth and flexible synthetic resin. They are seamless and extremely smooth.
Half an hour later, the two returned to the center of the room. They completed the exploration of the two walls and began to make routine contacts. "Is Mr. Zhang here? Let Mr. Zhang speak. Over." Xiao Liping held the walkie-talkie in his hand and said for half a minute. Finally, a man's voice came from the intercom: "Secretary Xiao. I am Zhang Dapeng. Do you have any instructions?"
"You are a senior engineer, geological expert and architectural structure expert. I would like to ask if there are any suspicious divergence paths in our sonar model. For example, the passages hidden around this building. Over." Lao Xiao said in a deep voice. .
Zhang Gong thought for a moment and replied: "The formation sonar system is not an accurate detection instrument. But it should not miss such a large target. Judging from the model in front of me, the entire room is an accurate cube without any derived structure. You Did you find anything? Secretary Xiao."
Xiao Liping said: "I'm just a little confused. How will the detection sonar be interfered with? From a technical point of view, Over."
"Many factors, such as underground veins, cavities, very dense metamorphic rock formations, groundwater, magma and metal objects. Changes in geological density will be shown on sonar images, interfering with the acquisition of normal targets." Zhang Dapeng replied. "Wait a moment. .I will change the transmission frequency. It should be able to see more clearly. I will generate a sonar image with fourteen bands superimposed. This can eliminate interference to the greatest extent. Give me fifteen minutes. Secretary Xiao."
"Copy. You have half an hour. Take your time. Over."
After a short rest and replenishing water, Xiao Liping led Matrill to continue to explore the remaining two walls. The black man was now drunk. He changed his timid behavior just now. He waved the golden Desert Eagle pistol and shouted: "Look Ah, look. This is basically the fairy tale room in Disneyland. It's just that some guy who was too full and had nothing to do buried it under the ground in Batangas. I will send 10,000 people to dig this thing up. Come out and put it on the outskirts of Bangui as a tourist attraction and open it to the public... Ah, it feels so good to be the president. No wonder so many people want to become dictators. Hehe..."
"You are a democratically elected president. You have just taken office. Be careful of rebellion." Xiao Liping said coldly.
"The army was formed by members of the Freedom Crusade. As long as the military power is firmly in my hands, no one can oust me from the throne of the head of state in Central Africa." Matilil shouted triumphantly.
"It depends on who is the initiator of the coup. What if it is someone like Gu Tie."
"Well……"
The black man's forehead was dripping with cold sweat. Old Xiao was so happy that his ears were clear. Half an hour later, they completed the exploration and returned to the cable location. They heard the intercom repeating: "Gong Zhang calls Secretary Xiao. Worker Zhang calls Secretary Xiao. Received." Please answer."
"Copied. Please speak." Xiao Liping grabbed the walkie-talkie and sat down. He opened a bottle of water and took a sip.
"I'm Zhang Dapeng. The overlay modeling has been completed. I want to correct a statement. The underground building is not a perfect cube. It is shaped into the shape of a perfect cube. This is obviously intentional." said the other side.
"Explain it."
"I'm sorry. Secretary Xiao. I mean, through the imaging of several bands, we can see that there are vague shadows outside the cube room. They are distributed around and below the room. The range is very large, covering an area of 15 cubic kilometers. You may not be familiar with this unit of volume. 15 cubic kilometers is 15 billion cubic meters. This is quite an astonishing scale. The water capacity of the entire Qinghai Lake is only 105 cubic kilometers. Imagine this. This is hidden in Batangafu City The extension of the underground building is equivalent to one-seventh of Qinghai Lake."
Xiao Liping was obviously taken aback. He put down the water bottle, hesitated, and asked: "Are you saying that this huge shadow surrounding the cubic room is actually part of the underground building. It is just ignored by us because it is not easy to detect. "
Zhang Gongdao: "That's right. That's it. This building is much larger and more complex than we imagined."
"What if the shadow isn't a building. It's just some kind of metal vein."
"This possibility can be ruled out because some edges of the shadow have geometric shapes. It is impossible for nature to produce the 90-degree right angle of a standard protractor. However, the shadow is divergent in most areas. It appears as a blurry mass on the model. Clouds and fog. Unable to produce clear images. It may be that there are substances in the building materials that interfere with the propagation of sonar signals."
"What substance is that?"
"I don't know either. Secretary Xiao. But we can take samples for analysis. I will send you a coordinate. That is the closest position between the cube hall and the clouds. Use an impact drill to drill through the wall to get the sample. You can take a little Get out of the way. I'll use the No. 2 cable to send the impact drill and sampling drill down."
"receive."
Five minutes later, an aluminum alloy box swayed from the sky. At the same time, a guidance point appeared on the room model on Xiao Liping's wrist display. Open the box and assemble the impact drill. Xiao Liping adjusted the laser to point out a path. Follow the light across the hall to arrive. Next to the wall, he found that the place indicated by Zhang Gong was just above the small black door. The laser point shone brightly on the blue wall, making it a bit dazzling.
"Not a good idea. But I'm not afraid." Matrill said drunkenly.
Xiao Liping picked up the high-frequency impact drill. He pressed the drill bit against the wall and pulled the trigger. "Chug, chugging, chugging..." The high-frequency impact and the rotation of the diamond drill bit immediately drilled through the resin wall. The 60cm long drill rod gradually penetrated into the wall. Old Xiao calculated the time to penetrate the wall in his mind. "3.2,1..." The 40-centimeter-thick resin exterior wall was drilled through. At this moment, the violent impact caused the electric drill to fly out. "Pop." It was like being drilled. It was like a high-voltage electric shock. The Chinese man fell backwards and fell to the ground with a plop. Matrier screamed. "I'm fine." Xiao Li lay on the ground and waved his hands. He slowly sat up. His hands were numb. Half of a diamond-edged drill bit was nailed to his helmet. A hole was pierced through the glass goggles. It was only a few centimeters away from piercing his eyes. If he hadn't been wearing a helmet, the broken drill bit would have killed him long ago. life.
"Oh my god..." The black man was so frightened that he sobered up and began to tremble again.
Xiao Liping sat for a while to regain his strength. He slowly stood up and walked to the wall. He inserted the folded cane into the drill hole and poked hard. A very hard touch came. He took out the cane and squinted his eyes to look into the hole. He could barely see. There was a layer of gray material at the end of the drilled hole. The diamond drill bit did not leave any white marks on it. "Let's go back." He pulled out half of the drill bit from his helmet and turned around to walk towards the cable. "...The result. There must be something. Let's end it. What's going on?" Matrill, who was confused about the situation, followed behind. He was confused.
The two finally returned to Pan Shen Wine Cellar. Xiao Liping gave the drill to Zhang Dapeng: "Gong Zhang, if you can find particles here, then it is the sample you want. If not, then all detection is in vain. We have this kind of material You can't see through it, and you can't drill through it. It's a solid gray curtain..."
Zhang Gong was dissatisfied and said: "There is no material on the earth that is harder than diamond."
Ten minutes later, the test results came out. No metal or ceramic material powder was found on the surface of the drill bit. Only trace amounts of carbon were present. That may be the sample material. It may also be that the diamond coating of the drill bit peeled off. Zhang Gong said with a sad face: "Xiao Secretary, did you drill in the wrong position? This is impossible. Even the hardest metal should have traces that can be checked..."
"I know the answer." Xiao Liping said: "It is graphene. The hardest carbon nanomaterial in the world. A honeycomb lattice structure composed of six carbon rings. It is indeed harder than artificial diamond."
"I know about graphene. But the price of graphene with such good performance is more than 1,000 yuan per gram. Who has such terrible financial resources to cover 15 cubic kilometers of space with graphene." Zhang Gong opened his mouth.
"The guy who created this room..." Xiao Liping said. "...I didn't say he was a human being."
"...aliens." Gu Tie curled his lips. "Ancient humans."
"We have a simpler choice." Xiao Liping said.
"Genesis." Wu Tianlan said.
"Say it again." The Aston Martin sports car stopped on the side of the road. Bartholomew murmured as he looked at the vast snowy scene.
"He is a child of Genesis. I shouldn't tell you this. But my mission is coming to an end. Let's consider it a parting gift. Brandon." Wu Tianlan whispered leisurely. His voice was neither happy nor sad.
