There is a planet on the edge of the southern galaxies that appears to be gray when viewed from space, as if it were obscured by a thick layer of dust.

This is the Lingxi Star, and the main purpose of this planet is to pile up cosmic waste, to put it in layman's terms - this is a garbage star.

......

In the early morning, the sky was gray, and a large gray cloud hung under the sky like a lead block, as if it were about to fall at any moment.

On the lead clouds that are like mountains, a flock of dozens of giant birds, flapping two pairs of large and powerful wings, soar neatly in the sky, shuttling between clouds of different sizes, drawing a sharp route in the air. Then they swooped down to the ground, and then, with a terrible scream, the giant birds soared into the sky again, their huge claws clasping their bloody limbs, and swaying blood lines in midair.

Ling Xixing, the living environment here is the same as its appearance, it is very dangerous, and there are murderous opportunities hidden everywhere.

In the northern part of the planet, this is an endless mountain range, with steep peaks and strange rocks. From a distance, these peaks are like sharp knives, piercing into the sky, a veritable mountain of knives.

Knock, knock, knock......

On the mountain trail, garbage trucks are slowly moving, these vehicles are comparable in size to F-class space chariots, about 6 meters high, with 8 wheels on each side. These wheels are wrapped in thick alloy tracks that can walk on such rough ground.

Ahead, at the end of the mountain trail, you can see a deep cave with a lighthouse in front of it, and the searchlight at the top of the tower is constantly swirling, and it is a light to guide the way in the dim environment.

The garbage convoy drove to the side of the cave, where there was a hill-like steel fortress, and a group of robots stood at the gate of the fortress, quickly unloading the waste from the garbage truck and carrying it towards the steel fortress.

At this time, the doors of each garbage truck opened, and 4~5 people jumped down from each vehicle, all of whom were wearing protective clothing and moving quite flexibly. However, the protective clothing on this group of people is obviously a very old model, and some of them still have patches on their protective clothing, which looks quite shabby.

Looking at the busy robots in front of the steel fortress, one of the men in the group cursed: "We live in a defense cave, but these cosmic garbage can be placed in the alloy fortress, and even the garbage is better than our accommodation." Damn, the cleaner can't do this job. ”

"Ling Zi, you don't have to complain. If you don't do the cleaner, can the wife and children at home enjoy such good benefits? We signed a contract for 30 years, and you will be able to get out in less than half a month. A slightly shorter man next to him comforted.

A group of people chatted with each other and walked towards the cave not far away, and suddenly a voice sounded from the loudspeaker on the lighthouse behind them: "Hey, everyone, welcome back alive." Just now in the western part of Blade Mountain, I found more than 100 [Four-winged Iron Feather Vultures] out hunting for food, I thought the entire garbage fleet was going to be finished, and I was about to report to the Blade and apply for a new team of cleaners!"

Suddenly, the cleaners stopped and shouted and cursed.

"Mo Ling, you crow's mouth, Lao Tzu cursed you that you can't marry for the rest of your life!"

"You stinky woman, if we hang up and turn into a ghost, we will come to you to settle accounts. ”

"You dead woman, if you dare to curse us in the future, you will definitely tear your mouth apart. ”

The group made all sorts of rude gestures to the lighthouse, cursing for a while, and then turned and walked briskly towards the cave.

Entering the cave, the rows of instruments placed at the entrance of the cave lit up, and the rays continued to scan the group of people, followed by a crisp sound of ding dong.

An old voice rang out from the loudspeaker on the rock wall: "Scanned and not stained with any dangerous materials, guys, welcome to your work again today." ”

Hearing this, this group of people couldn't wait to take off their protective clothing one by one, cheered, and rushed towards the cave.

"Finally came back safely again. The man named Ling Zi took off his protective suit, showed his thin face, and muttered to himself: "In 14 days, my employment contract will expire, great!"

Someone tapped him on the shoulder, and a chubby middle-aged man stood behind him, and said with a smile: "Ling Zi, don't always count the time, I'll be jealous!"

Ling Zi scolded with a smile: "What are you jealous of, Lao Zheng, I didn't say you." Your previous employment contract has expired, but you have to renew it for another 20 years, can you blame others? ”

"Hahaha, no way. I am short of money! I can renew it again, and after I complete the contract, I will be able to fill the hole in my previous debts. Lao Zheng Dalu laughed at himself, changed his words again, and said seriously: "Ling Zi, it's not that I count you down. You have less than half a month left before the contract expires, so be serious during this time, don't always get distracted. How dangerous it is today, if it weren't for Xiao Yan's timely rescue, your car would have fallen off the cliff and your bones would have been lost. ”

"I'm sorry, Lao Zheng. Here's my question. Ling Zi showed a look of shame on his face, and suddenly remembered something, and looked around, "Hey, where is that guy Xiao Yan?"

The two turned their heads to look, and immediately saw the entrance of the cave, and a person slowly took off his protective clothing and walked towards this side.

This is a teenager with short black hair, a pair of bright eyes, and a shy smile unique to a teenager on the corner of his mouth, full of sunshine and vitality. Walking from afar, this young man seemed to be a faint luminous body, which made people involuntarily notice him.

Seeing Ling Zi and Lao Zheng, the young man waved his hand from afar: "Brother Ling, Uncle Zheng." ”

Looking at the approaching young man, Ling Zi's face showed embarrassment, and he said, "Xiao Yan, thank you for today." I'm so sorry I treated you the other day!"

Thinking of the many difficulties he had made to him when this young man named Xiao Yan first came a week ago, Ling Zi felt hot on his face, and he couldn't wait to find a hole to get into.

Hearing this, Xiao Yan couldn't help but be stunned, but immediately reacted, and said with a smile: "Brother Ling, what are you talking about, we work in a team, and we should help each other at ordinary times." I didn't care about the previous thing, Brother Ling's employment contract will expire soon, he must be in an unstable mood, so don't take it to heart. ”

Hearing the young man say this, Ling Zi secretly breathed a sigh of relief, he was also bold, patted Xiao Yan's shoulder, and said with a smile: "Okay, you kid is good." Let's go, Ling called me to invite you to drink, let's have a drink together. ”

Next to him, Lao Zheng became anxious when he heard this, and said in a loud voice: "Ai, you two don't talk to yourself! How can you miss me when you drink alcohol." ”

The three of them laughed and walked side by side towards the depths of the cave.

Behind him, the sky outside the cave suddenly lit up, a white light sprinkled down, and the entire ground seemed to be covered with a layer of silver light, and some rocks cracked in the light, and light smoke bursts.

Outside the steel fortress on the side of the cave, those intelligent robots had already finished carrying the waste and rushed towards the fortress quickly. Running a little slower, the shell of the machine was illuminated by the silver glow, and a series of sparks lit up immediately.

This is the phenomenon of high temperature during the day on the Lingxi Star - white and silver spots.

......

Walking along the path of the cave, Xiao Yan and the three of them chatted while walking, and the vision ahead gradually widened.

This cave is very deep, about thousands of meters underground, and the entrance to the cave has a special defense device, which can completely isolate the invasion of [White Burning Silver Spot].

After walking for a while, the vision in front of me suddenly opened up, and I saw a huge underground cave in front of me, and all kinds of houses in the cave were built next to each other. Although these houses are dilapidated, there are bursts of laughter, and they are quite lively.

Standing at the exit of the passage, looking at the buildings in front of them, the three of them had different expressions, Ling Zi sighed softly, as if he thought that he was going to leave in half a month, there was some complexity and reluctance in his heart, Lao Zheng was pale, maybe he thought that he would stay here for 15 years, which is quite a long time.

As for Xiao Yan, the young man always had a smile on his face, but he was scolding wildly in his heart, grandma is a bear, brother, I have been here for a week, why hasn't the military department given further instructions?

This teenager is none other than Sun Yan, a week ago, he came here on a container spaceship, and with the letter of appointment directly issued by the Yahuang Foundation, he became a member of the Yahuang Foundation's cleaner team in the Lingxi Star Blade Mountain area.

Here, Sun Yan's name is Xiao Yan and he has no surname. However, this is not surprising, as there are many cleaners here, and most of the people who come here bury the past.

The three of them walked on a small road, an underground cavern that was so large that the complex was large enough to be called a village. However, the cleaners here prefer to call it a camp.

In the huts beside the road, children occasionally get in and out, happily playing peek-a-boo, and see the happy expressions of these children. Sun Yan couldn't help but be in a trance, as if the purgatory-like environment on the ground was very far away from here.

After walking a little further, a room came into view.

The room was unlike the rest of the camp, the walls were mostly made of alloy, and there was a noisy synthesized electronic sound from time to time, and a turbine-like thing spinning at the top of the house.

On the third day after coming here, Sun Yan learned the name of the thing - radar.

It is said that this instrument is a popular detection device in the age of the home planet, and it is an absolutely antique thing, and it has been obsolete since the time when humans were able to carry out conventional interstellar voyages.

However, in a resource-scarce environment like Ling Xixing, this old-fashioned device has played a big role, detecting the sneak attacks of the [Rock Beast] many times, allowing the entire camp to survive.

The person who turned this antique out of the garbage heap and reused it was none other than the owner of this room, Professor Luo, who was also the owner of the old voice at the entrance to the cave.

This semi-metallized house is called Professor Luo's laboratory.
