The elevator stopped with a "ding-" sound, the red light on the door lit up, and a letter "Ω" faintly appeared in the darkness.

Ω is a Greek letter that is pronounced "Omega", which is the last letter of the Greek alphabet, so it has another meaning, "the end of all things".

The middle-aged man leaned against the inner wall of the elevator and smoked, wearing a one-piece blue overalls, the clothes were very old, a little white, and the sleeves were stained with dark oil that could not be removed, looking like an auto mechanic. The elevator door slowly moved open, and a faint cold wind blew in, and the space outside the door was pitch black.

The middle-aged man didn't rush out, he raised his eyelids and glanced out, and then buried his head in a cigarette and swallowed the fog, and the white smoke swirled in the elevator car.

The elevator didn't move either, and the doors stayed open.

Both sides are not in a hurry, they are not short of this cigarette time.

The car was silent, the middle-aged man did not make a sound or move, his head was not raised, the flame of the cigarette was slowly extinguished, the middle-aged man wanted to finish this cigarette and then go out, he was reluctant to lose it, because this is a Chinese, in this era, China is a rare good cigarette, all the cigarettes of the middle-aged man are scooped out of the garbage heap in the forbidden area outside the college, only one pack of ten packs of cigarettes on average is Chinese, of course, there may be fakes.

The cigarette quickly burned to the bottom, and the middle-aged man smacked his mouth for a moment, sighed and sighed that it was really a good cigarette, raised his hand and scratched the scar at the corner of his eye, and took off the dirty hat on his head and clamped it under his armpit.

He straightened the collar of the sleek, bright elevator wall, buttoned it up, pulled the hem of his clothes, and straightened the crumpled overalls to make himself look refreshed.

"Mr. Mechanic, you don't really have to worry too much about your collar." A soft female voice suddenly sounded overhead, "You've been tossing it for three minutes, but it didn't work. ”

"You care about me?" The middle-aged man pursed his lips and turned his head to glare at the camera overhead, "Did I let you in?" This is my private space, giving you three seconds to get out. ”

"Okay, Mr. Mechanic, I'll leave."

As soon as the female voice fell, the middle-aged man's eyes suddenly went dark.

"I'll fuck you! Turn the lights on for me! ”

Small LED tubes are lit up on both sides of the road in turn, they emit white light, connected in a line, outlining a one-meter-wide road in the dark, the middle-aged man walks in the middle of the road, where he goes, the lights are on, which gives him a feeling that the central leaders are inspecting the countryside, the soles of their shoes are tapping on the metal floor, and the sound is crisp and rhythmic.

But what greeted him here was not the secretary of the county party committee and village and town cadres, nor did he receive the wind and dust banquet and the red star second pot, but the rolling heat wave and the huge buzzing noise.

On both sides of the road are cabinets several meters high, they stand neatly on the ground like a continuous city wall, and there is no end in sight, huge servers are stacked on shelves, countless interfaces and knobs, indicators flashing red and blue, dense cables bundled together thicker than a person's waist, thousands of cooling fans rotate together, making a huge noise like the rotation of helicopter rotors, and at the same time pumping out the heat emitted by thousands of processors.

The middle-aged man walked along the road, tall cabinets passed by one after another, and those blue LCD control panels were beating numbers and curves, which showed that a huge amount of data flowed into these servers every second, and all the servers were connected to each other to form a huge information processing network.

Anyone would be stunned by such a sight...... This is really an amazing scene, reminiscent of the original supercomputers, those electronic monsters often cover an area of thousands of square meters, they have hundreds of millions of computing power per second, usually used to simulate nuclear explosions and predict the weather, but now that human society has been destroyed for decades, who can save such a high-precision and high-energy machine?

The man was very careful not to touch the cabinets, these cabinets have a strong static electricity, not allowed to touch at will, strictly speaking, the clothing of middle-aged people is completely non-compliant, when this computer room was just established, all the people who stepped into this place had to put on strict protective clothing, wear goggles and shoe covers, not even a single hair could fall, and fireworks were strictly forbidden - so the middle-aged man would finish the cigarette in the elevator, because he could not bring the flames in.

He followed the path through the rows of cabinets and soon reached the center of the machine room, where two walkways intersected vertically, leaving a small open space with a chair on the floor.

The middle-aged man sat down in a chair and slapped his face.

"Computer?"

"I'm ...... Mr. Mechanic. A soft female voice rang out from all directions.

"I'm here to inspect." The middle-aged man cocked his feet, "Don't you go 50 meters underground to your poor country, and you won't come to rub my feet?" ”

The computer was silent for a long time, "Unfortunately, Mr. Mechanic, I don't have the corresponding function...... The maintenance robots on the ground floor may be able to help you, but their robotic arms are generally more than 1,500 kN, and rubbing your feet may cause femur fractures. ”

The middle-aged man put away his feet stupidly, he almost forgot that this computer also had a group of robocops as bodyguards.

"What's going on lately?" He bent down, and the floor beneath his feet was a metal mesh through which the middle-aged man could see the lower floor...... He is now in the ground at a depth of 50 meters, which is more than most subways, but this is still not the deepest, and there is still a layer under the feet of the middle-aged man.

He could see the dark red light coming through, and the space beneath his feet was more like a deep well, filled with indescribably complex machinery, messy metal pipes winding and twisting, manipulators moving back and forth on the tracks, and beyond that, it was impossible to see clearly, the lines and pipes blocking his view.

"The reactor is working well, and there is still backup and redundancy of nuclear fuel." The female voice replied, "It is expected to continue to operate for another twenty-five years." ”

"So I have twenty-five years left without worrying about power outages?" The middle-aged man exclaimed, "Those fools above still think that all their electricity comes from solar energy...... In fact, the solar energy is only enough to boil the bath water for them. ”

"In principle, that's right." The computer replied, "However, the task of the reactor is to give priority to the power supply of the central computer, and the remaining electricity will be provided to the college as domestic electricity, and if the central computer is overloaded, then I will reduce the proportion of the college's domestic electricity." ”

"Overloaded?" The middle-aged man was stunned, "What can overload you?" Sean, that old guy wouldn't hide from me that I was building an atomic bomb, would he? ”

"It's the library." The female voice said, "Someone in the library borrowed the computing power of the central computer to analyze the structure of the virus, which is a very large amount of computing and occupies 80% of the process of the central computer. ”

The middle-aged man nodded, needless to say, it must be Anna...... The central computer is helping her with the research and development of white gin, which Anna herself does not know, the central computer is connected to the library's computer from the background, and helps her analyze the structure of the virus at a speed of one billion floating point operations per second, otherwise the library's broken computers will not be able to complete the work until the end of the world.

"The reactor down there won't leak, will it?" The middle-aged man suddenly asked, a little worried.

At his feet is a fast breeder reactor, on the eve of the destruction of the world, the fast reactor is the most advanced type of reactor in the field of nuclear power, unlike traditional light water reactors, fast reactors do not produce a lot of nuclear waste, so this reactor can be built underground for so many years.

The reactor is fueled by 98 percent weapons-grade plutonium-239 and uses molten liquid metal sodium as a coolant, which cannot be stopped once it starts operating, because the sodium solidifies as soon as the temperature drops.

"The likelihood of a leak is extremely low and only theoretical." The female voice replied, "Compared to the reactor fuel leak, the academy is 10 million times more likely to be attacked by hunters. ”

"So I don't have to worry about this big nuclear bomb exploding one day, right?"

"It's just a reactor, not a nuclear bomb." "It lacks the necessary conditions to explode, so it can't explode anyway." ”

"OK, OK...... the middle-aged man waved his hand, "The situation is confirmed here, everything is normal, you are very competent as a housekeeper, I will give you a few kind words in front of that old guy...... I'm here to find the girl, Mommy-san, hurry up and call the girl out to accompany me! ”

The computer was silent for a while.

"Hey, can't you hear me? I want a girl to talk to me about Shakespeare and Yeats! The middle-aged man shouted.

A string of silver bell-like laughter suddenly sounded in midair.

The middle-aged man was stunned.

A silver-white pillar of light suddenly fell on the top of her head, and the translucent plain white girl hung in the air and bowed down, stretched out her slender arm, and gently touched the middle-aged man's forehead with her index finger, and then squinted and smiled.

"Who is talking about Shakespeare and Yeats?"
