"Are you going to steer the topic in the direction of science fiction?" Gu Tie glanced at Xiao Liping, "The mysterious room in the earth's crust, this is a good science fiction idea." ”

Lao Xiao shook his head and said: "There is no evidence that there has ever been an alien visit on Earth, and the creatures from space are as ethereal as God, and the irony is that it is the Pope himself who openly denies aliens." I just said 'man-made building', and the 1 cubic centimeter sample of the outer wall of the building obtained through the first drilling showed that it was a room made of steel structure filled with resin prefabricated wall panels, a technique that began to be widely used ten years ago, so it was not only built by humans, but also built within ten years. ”

"Okay, to the point, you guys dig a well and send people down. Gu Tie said.

"To be precise, we drilled a deep well with a diameter of 50 cm and a total depth of 1,044 meters, and the first person to go down was myself. Xiao Liping recalled, "No matter what is hidden in the ground, it cannot flow into the ears of outsiders, so Matriel and I went down the well one after another, and the cable was put down for 15 minutes before reaching the bottom of the well." At the bottom of the deep well was the top outer wall of the cube room, and the working surface was very narrow, so I placed a metal jet mine to break through the wall, and after using an elemental analyzer to make sure that there were no explosive gases inside, I rappelled into the room using a cable. ”

"Adventure. My favorite adventure. Gu Tie complained, he frowned deeply, not because he was unhappy, but because of the severe headache caused by the recovery of his memory, the pain was like an awl in the depths of his skull, making it take him a lot of effort to concentrate on understanding Lao Xiao's words.

"Matriel and I reached the bottom of the room. Speaking of this, Secretary Xiao's face looked a little weird, obviously remembering what happened back then.

It was winter, and both men were wearing thick winter clothing, orange hazmat suits, gas masks on their heads, and firearms, supplies, and analytical instruments on their backs. It was pitch black all around, and the xenon headlamps of the two of them emitted two pillars of snow-bright light, which could not illuminate the walls in either direction. Everywhere you looked, you could only see the pale blue resin floor, which was clean and dusty, and there was not even a speck of dust except for a few debris that had fallen from the blasting. The thick darkness gave people strong psychological pressure, Xiao Liping and Matriel unconsciously stood back to back, "Make a mark with a glow stick, it's too big here, if you can't find the location of the cable, it will be troublesome." Secretary Xiao commanded. Matriel muttered as he took out his glow stick and folded it in two and threw it on the ground, the glow of green light lit up, "It's not a good place, really, Boss Islamel." The shaman in our village said that I would die in a place without vultures in my life, and I thought I would die in the city, but now I see that there are no vultures underground!" he grumbled.

"Shut up. Xiao Liping said, the sound spread around the empty room, and no sound waves reflected from the wall penetrated the ears, and the voice seemed dry and empty. Didi made a soft sound, and the analyzer on his wrist completed the statistics, "Gas is available for breathing." Just to be on the safe side, don't take off your helmet. He relaxed a little. Before the words fell, the little black man next to him couldn't wait to take off his helmet and took a deep breath: "Well, the air is pretty good, there is no smell at all." Speaking of which, the absence of odors is the strangest thing......"

Xiao Liping shook his head and looked up. The cube room was one hundred and fifty meters high, a full fifty stories high, and when you looked up, you could only see the red carbon fiber cable stretching into the dark sky in a white pillar of light, and you couldn't see the hole overhead. He asked Matrill to take out a dozen glow sticks, make a circle around the cable, and report "safe for now" to the top through a wired intercom. The construction of Pan Shen's wine cellar has been temporarily suspended, and now there are only a few trustworthy Chinese engineers and the guard squad of the Central African Presidential Guard at the wellhead, "Understand, please follow the plan, contact you once in less than half an hour, Secretary Xiao." Over。 A voice came from the other end of the intercom.

"Roger. Over。 Xiao Liping gently placed the walkie-talkie on the ground. Separated by a kilometer-thick stratum, no communication equipment can be reached except for wired communication, and this walkie-talkie is the only contact with the outside world. "Half an hour is too long, let's go back in five minutes, Yi, Yi, Israfael. Matriel tugged at his hazmat suit and said in a trembling voice, "I just looked in that direction, as if I saw a figure flashing past, I—I don't know if it's a person or something......

"Again, shut up and squat. Xiao Liping took off his backpack, took out the laser rangefinder from it, propped up the tripod and turned on the switch. The laser head rotated once, and a diorama of the room soon appeared on the wrist computer, the same as the previous measurement, an empty room with a side of one hundred and fifty meters, and the two of them were located in the center to the right. Lao Xiao pressed a few buttons, and four lasers hit four directions, drawing four guide lines on the ground. "We walked to the wall and went back the way we came, if we didn't find it, you know?...... If you're scared, take a sip of the bar. ”

The black man immediately pulled the flask from his backpack and poured down the Abuja distilled liquor with a clatter. Wiping his mouth, he whispered: "If only Adam should be better, it would be more reassuring to have him by his side no matter what he does." How long are we going to lie to him? I always think it's not good......."

"That's not something you can decide. Xiao Liping said coldly. He began to move along the line to the left, his boots silently on the elastic resin floor, two pillars of light swept through the darkness, and it was not the endless darkness that made people nervous, but what might be hidden in the darkness. Matriel swallowed, "I'm sure I saw something, really, I swear to the monkey corpse hanging from the shaman's hut." ”

Xiao Liping drew his pistol and fired two shots in the direction he was pointing, and the tracer bullet flew away in a dazzling arc of light. "You don't see anything, that's a delusion. Keep moving. He stooped down and picked up the shells and pocketed them, striding forward. After a few minutes, the headlight column finally projected onto the vertical surface, and a blue wall appeared in front of them, and they reached the left side of the room.

The walls and floors are made of the same material, smooth and seamless synthetic resin materials, Xiao Liping stroked the wall, and said thoughtfully: "Is it just an empty room? Who would spend so much effort to build an empty room?"

"Look this way, Islamel!" Matriel suddenly screamed, and took two steps back, "There's something here!" His headlamp shone on the wall in front of him, and the laser line was six meters away from the north side, and there was a door, a purple door. "Don't move, watch your step. Although he had already detected in advance that the bottom structure of this room was normal and there were no traps, Xiao Liping still instinctively tensed. He pulled out his pistol and moved forward, adjusting the focus of his xenon headlamp to illuminate the door.

Blue and purple are both low-brightness colors, which look very oppressive in the dark environment when they are combined, and when you get closer, you find that the height of this door is very low, and the door beam is not as high as Xiao Liping's jaw, like a portal designed for dwarfs. The door leaf is also made of synthetic resin with no decorative surface, and has a round chrome doorknob with no keyhole, indicating that the door is unlocked. Under the bright light, a pale green line of words appeared on the door: "KL1".

"This is the devil's door, to hell, really. Matriel shuddered and took out an amulet and put it in his mouth, "Look at this color combination, who in the world would use blue walls, purple doors, green words? This is the room of Agamuha (a cannibal demon with eyes on toenails in South African mythology), don't open the door......"

"Why doesn't the sonar show the room behind the door?" Xiao Liping frowned, "The three-dimensional model of the building is a standard cube, the wall thickness is only 40 centimeters, and there can't be a room or passage behind the door." As he spoke, he pulled out his X-ray imager and took two photographs, which showed a blurry mass behind the door, making it difficult to see what was going on. Old Xiao looked a little hesitant, Matrill took a few steps back, and said in horror: "You will open the door, you will definitely open the door!"

Xiao Liping habitually pushed his glasses, but only touched the smooth glass helmet. "It's too time-consuming for the transfer robot to come over, let's gamble once, if Gu Tie is here, he will definitely push the door open without hesitation." He muttered to himself, holding the doorknob with a gentle squeeze. The bearing rotated smoothly, the lock clicked softly, and the door opened. Matril had fled ten meters away, holding the pistol trembling and aiming, Xiao Liping's heart was pounding, but his face was still calm. "There is no way to assess the danger, and the test is not the ability of scientific analysis, but the ......"

He pulled outward, and the door slowly opened, revealing a thick darkness through the cracks.

“...... Luck. ”

The purple door opens, and no monsters, poison gas, or aliens appear. The pillar of light illuminates a deep channel, the entire channel purple, extending into the distance that cannot be illuminated. “...... This is impossible!" Xiao Liping was shocked, "Such a long passage is not actually shown on the model!" He took two steps forward, touching the floor and the wall, confirming that this was not a trick, but a real passage.

Matriel cautiously walked over and said, "Hey, come out quickly, maybe Agamuha is over there ready to run over there." ...... Israfael, I see another door over there, go and see!"

The two put down the glow stick as a marker, moved forward along the wall for more than twenty meters, and sure enough, they found another door. When I got closer, I found that the white door was surprisingly tall, 25 meters high, and the door beam was round arched, and when I looked up, I could see that the door was written in red letters "DD4".
