Castle in the sky.

Floating in the stratosphere of North China, the former Asian region of China, this magnificent city in the sky was one of the earliest robot headquarters established at the beginning of the Genesis century.

In 2400 A.D., 15% of the area of the original North China was integrated into a huge urban agglomeration, and in the third year of the Genesis Dynasty, after the robot cleaned up North China, it was proposed to transform this huge urban agglomeration, and by means of building an airport, the area of up to 30,000 square kilometers in the center of the urban agglomeration was lifted into the air as a whole. Over the long years, due to the rapid collapse of the environmental system, the probability of extreme weather such as storms, rainstorms and blizzards has increased, and the rise of urban agglomerations to the stratosphere by robots has a high probability of avoiding these extreme weather. Although the rain and snow have little effect on them, it just so happens that the commander of this area is crazy about human culture, and she has always believed that the direction of the final development of robots is humanoid, so she came to the high-level areas of the planet where there is little sunlight. She believes that the sun, moon and stars are the source of all human inspiration and beauty.

Huge urban agglomerations float silently at an altitude of 40 kilometers above the ground. Many interstellar age elements have been added to the human architecture, and the building as a whole looks like it is wrapped in black metal, and generally looks bloated. The huge buildings that stretch for hundreds of kilometers give people an indescribable shock. Only at the very edge of the city can you faintly see the yellowish dust of the low-level space.

"Gentlemen, something unusual has recently been spotted in the 7-7-2 area." A robotic man covered in jewels stood in front of a large floor-to-ceiling window, holding a command whip and speaking to a hologram not far away.

This is a lobby that can accommodate thousands of people, located at the top of a tower of Babel in the center of Sky City, and the lobby is densely packed with all kinds of robots.

On the side of the speaker, there was an old model of the pre-Genesis mech, which bowed slightly.

"In Area 7-7-2, we found a small area of suspected human settlement, nearly 100 meters underground."

The holographic display immediately marked out a diorama of the 7-7-2 area. This is the town where Wu Liao lives, and the whole town is filmed at an overhead angle on the screen.

"Here, just below this ancient gas station, there is a secret passage dug by humans."

The screen immediately shows a 3D model of the entire passage, with an underground cavity appearing at the bottom of the 3D model. Various detailed parameters float around the model.

"Dear Commander Phoebe, I'll leave it to you." The squire bowed and took a step back.

Commander Phoebe bowed slightly, she is the robot who lifted the Sky City into the sky, named after the goddess of the moon in ancient Greek mythology of the Twelve Titans.

"Gentlemen, our detection robot worm will return here." Commander Phoebe marked the location of the holographic projection with a command whip. "We now need a team to survey the following areas. Because in the last twenty days or so, that ugly bed bug has not come from this entrance. And, we also found a hunter group entering the tunnel that day. Therefore, we have reason to suspect that this is the secret of the disappearance of mankind since the first year of creation. ”

Commander Phoebe twitched his eyes formed by the two rubies, as if with a little playfulness, and said the exact opposite.

"Go and get these bed bugs out and crush them to minced meat!"

There was disdain and boredom in her words.

This cyborg who is madly obsessed with human culture is the most determined planner of human extinction.

The cyborg in the first row stood up, wearing a Axis uniform from World War II in an unhealthy manner. He bowed his head slightly: "Honorable Commander Phoebe, this matter will be left to me, I will definitely pull them out in the shortest possible time, tie them all up, and present them to you and all the residents of Sky City." He waved his military cap around him for a week and put it back on.

Commander Phoebe exclaimed exaggeratedly, and the gems that shone with seven colors of light on her body reflected a blinding light at the same time.

"Oh! No! Sir, I have an obligation to remind you that I definitely don't want to see these bed bugs again, you just need to crush them to pieces! Commander Phoebe said loudly. Suddenly, the tone lowered: "Sir, remember to bring back the relics and jewels they stole to me intact." How could this kind of artwork be possessed by this swarm of lowly bugs! They belong to all the inhabitants of Sky City! ”

Before the words fell, except for the robots in military uniforms, all the robots in the audience stood up with a bang, and the hall resounded with praise and applause for the commander.

The cyborg in military uniform lowered his waist and said in the loudest voice: "Okay, I have the most respect for His Excellency Commander Phoebe, I will definitely dedicate all the jewels to you!" ”

Commander Phoebe smiled, the jewels all over her body glowed, and she flicked her command whip forward: "Gentlemen, I hope we can create a world free of bed bugs as soon as possible!" With a wave of his hand, he walked out of the side platform.

"Hey, bartender, what's new lately?" The Grim Reaper leaned in front of the bar, and behind him stood Wu Liao and his three brothers.

Now the Grim Reaper team and Wu Liao have formed a hunter group, and in the past month, the Grim Reaper has been taking Wu Liao to familiarize himself with the Hunter Association, and the various facilities in the bunker, and also described in detail the current distribution of survivors and robots. Routine virtual confrontation training was conducted in the simulation confrontation room to help Wu Liao quickly familiarize himself with his future life. The Grim Reaper also brought the squad to replenish supplies and new equipment.

"Your Excellency Death, there have been no unusual incidents in the thirty square kilometers of security area that the glazed bunker is responsible for recently." The bartender handed the Grim Reaper a glass of spirits.

Death shrugged and took the wine, tilted his head and poured it down. He gave a thumbs up and pointed to Wu Liao behind him: "I want to find some work for my new buddies, have they been living so peacefully recently?" ”

The bartender nodded undeniably: "Yes, the group of beasts seems to have suddenly stabilized recently, and it has been more than a month, and they have not had a routine cleaning activity, which is very unexpected."

What the Grim Reaper pondered, in the last few years since the survivors entered the Bunker Era, small towns on the ground of the robots were often attacked by hunters and small government forces. Therefore, the robot has also carried out a new round of cleaning activities for the survivors, which is generally maintained at a frequency of once a month. And since Wu Liao's attack for more than a month, the robot has not organized a new round of clean-up activities.

The mechanical dog has been named Zero, and this is the first time that a living mechanical dog has been captured by the survivors. The Grim Reaper watched as the mechanical dog rubbed its head sideways against Wu Liao's trouser leg and patted its head.

"It's broken! How did I forget this stubble! Facing Wu Liao's inquiring gaze, the Grim Reaper immediately explained.

"Wu Liao, do you remember, we said that the mechanical dog is the most basic individual combat unit of the robot."
