Liu Weiping was taken aback, his main engine was running rapidly, calculating all possibilities, could it be that there was a world of Homo sapiens hidden in the depths of the Siberian underground? That's impossible!

He couldn't help but stretch out his hand to touch the other party's face, as soon as Liu Weiping stretched out his hand, he immediately understood what was going on, it turned out that he had fallen on a flat mirror, and all he saw was his own reflection. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Liu Weiping stretched out his hand to wipe off the mist on the mirror, the mirror was silver-white, Liu Weiping got up and took two steps outward, the mirror was suspended in mid-air, and the opposite side was a roaring waterfall. Liu Weiping turned around and walked inside, the mirror seemed endless, and there was no end in sight no matter how he walked.

Liu Weiping calculated his displacement while walking forward, and had moved more than a thousand meters, at this time the fog began to weaken, and judging from the light reflected by his eyes, the mirror on the ground was no longer horizontal, his reflection was obviously distorted, and the mirror began to show a curved surface.

Slowly, the mirror slowly rose a slope, and Liu Weiping was still searching all the memories in the host, trying to find clues that matched the scene in front of him. At this time, an amplitude modulation signal appeared in the background noise of the analog radio wave receiver that he had barely used in his body, and Liu Weiping noticed that the frequency at this time happened to be 31.4 kHz!

31.4 kHz, what a familiar frequency, Matsushiro earthquakes, high-frequency potentiometers and brain waves, all the data about this mysterious frequency was called up from the memory at once, is it a seismic wave? Why is there no radio wave with such a stable frequency at the bottom of Lake Baikal?

While Liu Weiping was analyzing the radio waves, his feet did not stop and kept moving forward. Speculating from the reflected light of the mirror, Liu Weiping concluded that he was on a hyperbolic plane, the mirror was getting more and more shaky, Liu Weiping couldn't help but lean down and crawl forward, after a while, he found that he couldn't climb anymore, not because the energy was exhausted, the nuclear decay battery pack in his body was enough for him to be active at full power for four years, but the curvature of the mirror was too great, and the place more than 20 meters in front had become vertical, and a slender pillar had been stretched upward, and soon disappeared into the fog.

The signal of 31.4 kHz is getting stronger and stronger, Liu Weiping curiously scanned the amplitude of the wave, and he suddenly found that the radio waves seemed to be repeating some kind of signal. Liu Wei turned around a few times, and the direction of the signal source was roughly determined, and it seemed to be above his head. Liu Weiping looked at the towering pillar, he lowered his head and continued to climb in the direction of the center.

There seems to be something wrong, Liu Weiping sensed the error of the sensor in his body, yes, it was a gravity sensor, and Liu Weiping's weight slowly decreased. Fortunately, Liu Weiping was a homo sapiens, which allowed him to calmly face the strange phenomenon in front of him, and he thought that his gravity sensor was out of order at first, but quickly corrected his judgment.

Because Liu Weiping found that the steep hyperboloid was not so unclimbable, with the increase of this curvature, Liu Weiping's weight began to accelerate the loss, he gently pushed the ground with his hand, and actually pushed more than 200 kilograms of body off the ground, and the reading of his gravity sensor was only more than 30 kilograms.

He alternated his hands and kept pushing the almost vertical curved cylinder, although Liu Weiping couldn't figure out the reason, but he could conclude that all this must be related to the mirror cylinder in front of him, he didn't dig deeper, and began to climb up, ready to find out.

His host did not pause, continued to analyze the amplitude modulation wave of 31.4 kHz, Liu Weiping saved the brainwave decoding program written in Boston Dynamics in his own host, he was a little suspicious that the received radio waves were human brainwave signals, although he was not very sure, he still wanted to experiment, he knew the complexity of his brainwave decoding program, so he just carefully allocated some computing resources, the result was obvious, still nothing.

The mirror cylinder is getting thinner and thinner, Liu Weiping has floated upwards for almost 800 meters, and the gravity at this time is close to the state of space, but he has many memories of spacewalking, and it is effortless to control his physical state in such an environment. Liu Wei slowly climbed the surface of the cylinder, reduced his speed, and slowly floated upward.

The column body is already very thin, and it is about forty meters in diameter by visual inspection. Suddenly, Liu Weiping found that the abnormality was broken, the silver-white smooth mirror surface was broken, and the surface was full of wire mesh, and the hole was about enough for his body to drill into. Liu Weiping didn't want to immediately stand up and climb in through the wire mesh.

With a flick of the wire mesh, his head and body had already rushed in, and before he could adjust the posture of his ass, the sudden gravity pulled Liu Weiping's head and fell down. Liu Weiping secretly said that his voice was not good, and he curled up and contracted his body together, ready to resist the impending impact.

But the time of the fall was very short, and in milliseconds, Liu Weiping had already landed, he checked his gravity sensor, and everything was back to normal. Liu Weiping got up from the ground and began to look around, everything in front of him was familiar, as if he had returned to the nineteenth-century electronic laboratory, the rows of racks in front of him, the tubes on it were dense and shiny, and everything told Liu Weiping that this was the result of human civilization on the earth.

Liu Weiping wandered between the machines to carefully check the layout, after a few back and forth, he was more or less able to guess the role of this machine, from the structural point of view should be the last century abandoned analog computing circuits, analog computers and digital computers together to undertake a variety of human computing tasks, but with the integration of semiconductor circuits is getting higher and higher, analog computers slowly withdrew from the stage of history.

However, it is really strange why the analog computing circuit in front of us uses tube technology, and if it is the masterpiece of the Soviets, why not use semiconductors but tubes with such underground efficiency? And how to explain the gravitational abnormality outside? A series of questions made Liu Weiping's body swing and almost sit on the ground.

Liu Weiping went around again, he looked up, the tube building went all the way up, the heat emitted dispersed the fog outside, the visibility was much better, it seemed to be an antenna on it, and the 31.4 thousand hertz signal was emitted from the antenna. Could it be that all these devices are designed to emit this AM signal? Why do you want to use such a complex analog calculation circuit for such a simple signal, and does the owner of this antenna want to load some complex data on it?

Just as Liu Weiping was pondering, the outside of the wire mesh suddenly lit up, and the colorful light was unpredictable, shining on Liu Wei's face, as unpredictable as his complicated calculation program.

"Jiko, this is what Tadashi Ito is talking about?" Liu Weiping muttered to himself.
