Although he didn't know the function of this mechanical part, Qi Lin still put it away very carefully.

Purple quality items are all extremely rare treasures, and you can know it just by looking at the role of the corpse king serum - but what Qi Lin doesn't know is that the probability of causing human mutations and mutations to become evolvers like the corpse king serum is simply as low as death, and in the research institute of the shelter, most of the experimental subjects who were directly injected with the high-level mutant biological serum died directly.

Killing the mutant fathead fish and the experience of completing the task made Qi Lin rise to the third level, and at the same time, the wisdom brain permission [task bounty platform] was opened, Qi Lin took a look, and sure enough, the most conspicuous task was the reward for himself, but the amount of this bounty, if he could, he wanted to kill himself to receive it, anyway, it only takes 10,000 resource points to buy a resurrection chance, and the bounty has accumulated to more than 20,000.

After packing up his equipment and saying goodbye to the slurred one-armed zombie, Qi Lin returned to the off-road vehicle and found a safe and hidden place to go offline.

The Vault Mastermind stipulates that each person must be active in the game for more than 10 hours a day, and the rest of the time is allocated by themselves, or as usual by working to earn resource points other than the quota, Qi Lin has played for exactly ten hours and four minutes so far.

When going offline, you must be in a non-combat state, otherwise Qi Lin can use the "offline escape" to avoid the edge before at the gas station. When offline, the backpack and personal gear will disappear with the character, but the vehicle will remain in place, and the player will only be able to take the vehicle's activation key with them.

Therefore, Qi Lin pulled out a large piece of canvas used as a mat in the off-road vehicle, covered it on the body, and evenly smeared loess on it, so that from a distance, it looked like a stone.

After doing all this, he called out the virtual control panel in the game and chose to "leave the game".

……

Sitting up from the game pod, Qi Lin didn't have any other discomfort except for feeling a little dizzy in his head, it seems that even the lowest-end game pod distributed by the slum is quite mature, and the full immersion technology used is quite mature, it seems that the upper echelons of the shelter and the mastermind should have had this plan a long time ago.

Looking at the game cabin beside him, Xiao Lei was still immersed in the game world, Qi Lin moved his hands and feet, planning to go to the black market first.

The structure of the underground shelter slum is a labyrinth of tunnels, with small rooms on either side of the tunnels for people, and all the oxygen in the rooms is rationed by the brain, but the air quality outside the rooms is very poor.

Turbid, foul-smelling, low oxygen concentration, and many harmful gases, anyone who wants to leave their room must wear a breathing mask.

Qi Lin lived in this "Room F37 of Shelter No. 187" three years ago, and Xiao Lei was the "roommate" who moved in half a year ago, according to the people who brought Xiao Lei, Xiao Lei's parents were "excavators", died in an underground tunnel collapse accident, after the accident, Xiao Lei's family's residence in the middle area was repossessed by the company, and he was randomly thrown to Qi Lin.

Excavators, one of the heavier but more well-paid occupations among the inhabitants of the Middle Zone, are engaged in carving out new spaces underground, providing shelter for the growing population, and searching for mineral resources buried underground.

In recent years, as areas with more stable underground structures have been excavated, the upper echelons of the shelter have set the direction of excavation in areas with softer soil but deeper depths, and although the danger of excavation in these areas is high, the probability of discovering the most valuable resource, groundwater, is also higher.

Xiao Lei's parents were buried in the dark abyss more than 2,000 meters above the surface with dozens of workers due to the bending and breaking of a supporting steel column, and the 16-year-old child they left behind was directly demoted to the poor class, and his parents' pitiful inheritance was swallowed up by the big consortium responsible for the excavation work.

This is one of the reasons why Xiao Lei hates the rich so much.

In this underground world of the jungle, this is not uncommon, and it happens almost every day...... However, under Qi Lin's persuasion, Xiao Lei did not join an uprising group that had come to recruit him after hearing the news, but the other parents also died there, and the children who had been deprived of everything all joined in.

A week later, the plans for the uprising were revealed, and the children's bodies were hung on wooden shelves at the intersection of the tunnels, making the air quality in the tunnels even worse.

"How did you know the uprising was going to fail?"

More than once, Xiao Lei asked Qi Lin like this, but Qi Lin could only smile and say that it was luck, he didn't know how to tell this kind of sixteen-year-old child with a passionate mind that the driving force behind that uprising was the mining company where his parents worked.

Using the method of "creating an uprising" to eliminate unstable factors is almost the same as the pre-apocalyptic "fishing X".

……

Bypassing the intersection of several corpses that had long since been left with only white bones, Qi Lin walked to an airtight door that was three meters high, raised his hand and knocked on the door.

With a "Kala", a small window opened on the wall on one side, and inside was a dirty monitor, and after Qi Lin entered a few numbers, the airtight door slowly separated.

This is to pay the entrance fee to the black market, and if it weren't for this restriction, the entire underground black market would be full of beggars who come to "rub oxygen".

After passing through two airtight doors, Qi Lin's eyes suddenly opened up, and a brightly lit underground square appeared in front of him, and his ears were filled with the sound of shouting and bargaining.

"Hold, this is your ticket, you have to leave after the time, you know the rules." A hunched old janitor stuffed an irregular piece of paper into Qi Lin's hand, on which was written in crooked charcoal, "10 resource points, nineteen fifty." ”

Underneath these words is an anti-counterfeiting stamp pressed with a steel seal.

In the black market, he has to pay five resource points to the master of the black market in one hour, which means that Qi Lin must leave before 2150.

"I don't know if I can find something good today......"

Qi Lin walked to a stall near the entrance of the plaza, where some general parts of firearms were sold that were discarded before the end of the world or handmade after the end of the world.

These things that are absolutely contraband on the outside can be bought and sold in this black market, and even this is only one of the most insignificant goods, which shows that the controller of this black market is definitely a very terrifying bigwig.

But none of this has anything to do with Qi Lin, one of the most important purposes of his coming to the black market is to find some usable parts, and then use his extraordinary understanding of firearms to assemble some finished guns and resell them to weapon stores in the black market.

He would never sell his weapons directly to the rebels, and this was also to be on the safe side, although the price of the weapon shop owner was slightly lower, but since the guns he made became famous, the price of these weapon shop owners was not much lower.

The guns produced by "Crosshair" are all good guns, which is a fact recognized by Vault 187 and even several nearby shelters, and this "crosshair" is Qi Lin's own trademark.

The guns he made would use a cross and circle on the grip to depict a simple crosshair icon, which was Qi Lin's habit, and when he was a precision shooter in the mercenary unit before, every gun he had modified also had this crosshair pattern on it.

Although this sign is tracked down by the Vault Administrator when it appears in the weapons of the rebel forces, it is usually broken when it reaches the black market, which is one of the reasons why he never sells weapons directly to users.

One more middleman, one more security.

Just as Qi Lin was squatting in front of the stall, selecting parts, he suddenly heard a few people who were shopping on the side suddenly say: "I heard that the material warehouse of Vault 188 was burned down by the rebels, and the entire shelter is in a material crisis, and I am planning to transfer things from us." ”

"Why? Let them starve to death! ”

……

Qi Lin didn't stop looking at the parts in his hand, but he was a little puzzled in his heart, burning materials? This is indeed a stupid idea, but in this way, I am afraid that it will really make a big mess......
