The oxygen content in the shelter's tunnels is so low that even normal human breathing is enough, and if you smoke here, you won't be able to take a few puffs before you smoke a cigarette.

In some tunnels, the accumulated corpses decay and ferment in an oxygen-deficient environment, generating a large amount of methane, commonly known as biogas, and if an open flame is easily used in such a place, I am afraid that even a complete corpse will not be found.

Since the redshirts wanted to smoke, they definitely couldn't smoke in the tunnel, and as far as Qi Lin knew, the closest place with open gas supply equipment was a small trading market, although it was past trading hours and the gas supply pipeline in the market had been closed. However, compared to the tunnel, the air environment there is quite good.

It's a bit stinky, but at least it's enough to make people take off the breathing mask on their faces.

The red-shirted gang had walked twenty or thirty meters, and several finger-sized holes had been cut in his homemade breathing mask with tools, and the inferior cigarette he was holding had come out of one of the holes.

He took out a plastic lighter from his pocket, and with a light click, a flash of electric sparks, and a small flame jumped up, but before he could put the cigarette up, the faint flame was extinguished.

The oxygen content is too low to support combustion.

"!"

The man cursed, and fired a few more times, but each time it went out faster and faster, until at last only the electric sparks kept flashing.

At this time, he realized that it was the lack of oxygen in the tunnel that prevented the lighter from being lit, and he cursed a few more swear words, and then walked leisurely in the direction of the trading market.

The market is a full five hundred meters away, and if you move at this distance, you can definitely guarantee that you will not attract the attention of another Red Shirt gang.

Qi Lin followed closely behind the other party, the two walked out more than two hundred meters one after the other, Qi Lin suddenly accelerated, quickly approached the back of the Red Shirt Gang, ripped off the other party's breathing mask, covered his mouth and nose with his hand, clenched his right hand into a fist, and smashed the opponent's lower abdomen with a punch!

"Hmm-"

Before the Redshirts could react to what was happening, they felt an unbearable pain in their abdomen, and immediately let out a muffled snort of pain.

After a punch, Qi Lin quickly took out a black plastic bag and put it on the head of the red-shirted gang, and then, grabbed the opponent's wrist with both hands and twisted it hard-

"Ahh

The pain of the dislocated wrist caused the redshirt gang to scream again, but just as he was about to cry out for help, he suddenly found a cold, sharp blade against his neck, and a small part of the edge of the blade had cut into the skin.

This feeling of imminent death instantly turned the hairs on his body upside down, and the whole person froze in place and did not dare to move, at this time, even the dislocated wrist did not seem to hurt so much.

A foul smell came, and as soon as Qi Lin lowered his head, he found that the other party's pants were already soaked, and urine was dripping down the trouser tube on the ground.

So cowardly? Qi Lin was stunned for a moment, it seems that this guy is quite afraid of death...... Since you're afraid of death, it's easy to ask something out of this guy's mouth.

"Don't ...... Don't kill me...... Food, Resources...... What do you want...... I'll give you all ......" After a few seconds, the red-shirted gang said tremblingly, obviously, he regarded Qi Lin as the kind of bandit who was ambushed in a remote tunnel and specialized in robbing lone pedestrians.

"Don't be silent, I just want to ask a few questions." Qi Lin lowered his voice and said in a hoarse voice, dragging the red-shirted gang into a remote fork in the road, and then dug a small hole in the black plastic bag covering the other party's head that could just expose his mouth and nose, and buckled the other party's breathing mask.

The inside of the respirator mask is lined with a filter screen that can filter toxic and harmful gases, and a plastic pipe is connected to the bag used to hold the oxygen concentrator underneath.

"You...... What are you asking? Just don't kill me, I'll tell you whatever you ask! The vision of the Red Shirt gang was completely obscured by the black plastic bag, and he couldn't see Qi Lin's appearance, but from Qi Lin's sudden attack to dragging him here, the only thing he could be sure of was that this guy who kidnapped him was far superior to himself in combat, and it was only a matter of a moment to kill him.

Recognizing the facts, the Redshirts quickly became very submissive - few of them were not afraid of death, especially those of the gang members who often oppressed the poor but were themselves at the bottom of the Vault society.

"Tell me, what kind of business do you mean by 'big business' by your helper." Qi Lin patted the other party's cheek with a dagger and asked in a deep voice.

"W-What? What do you ask? The Red Shirt gang obviously didn't expect Qi Lin to kidnap him, and he actually asked such a strange question.

"I said, for the sake of a 'big business', your helper recently asked you to keep a low profile, so what is the content of this 'big business'?" Qi Lin repeated the question in more detail.

"Why do you ask this?" The Redshirts were stunned.

"Now I'm asking you, not you're asking me, if you want to live, answer me honestly." Qi Lin said, turned the dagger in his hand, and used the grip to peuke on the dislocated wrists of the Red Shirt Gang.

"Ah...... Yes......!! ”

The other party let out another scream, and Qi Lin removed the dagger.

"I ...... I also...... I don't know...... Helper's business...... How can we let a small character like us know......" The Redshirts gasped and said with some horror.

"You really don't know?"

"I ...... I really don't know......" Listening to this guy's tone, it felt like he was about to cry.

Qi Lin was a little depressed, and this redshirt gang didn't look like they were lying—if the redshirts really wanted to make any big moves, out of secrecy, it was reasonable for a guy like him to have no status in the gang in front of him.

However, given the recent chaos in the game world, Qi Lin couldn't help but be suspicious...... The so-called "big business" of the Red Shirt Gang is not planning to rebel, right?

Thinking of this, Qi Lin's heartbeat couldn't help but speed up a little - although he didn't have a good impression of the Vault official at all, if Vault 187 was also caught in the turmoil of rebellion, then it would mean that Qi Lin's peaceful days were coming to an end.

"Let me ask you a few more questions, first, has your gang bought a lot of new guns and ammunition during this time?"

The Redshirts nodded, then shook their heads.

"What do you mean? Yes or no? ”

"That...... Although there are a lot of guns added to the gang, they are not bought, they are given by others. The Redshirts said incessantly.

"Sent? Who sent it? ”

"I don't know......," the Redshirts shook their heads, "I've never seen them before, just a few days ago, they moved several large boxes to a warehouse controlled by our gang, and then left, and I was curious and sneaked a peek, and it was all brand new guns and bullets, and a whole small box of gold bars!" ”

As if he was afraid that Qi Lin would not believe it, he twisted his ass with great effort and said, "I secretly took one and hid it in the hidden pocket in the inner layer of my pants——"

When Qi Lin heard this, he took off his worn-out cargo pants, and sure enough, in a hidden pocket in the inner layer of the pants, there was a small gold bar the thickness of a finger.

This is an investment gold bar issued by commercial banks in the old era, the surface is slightly worn, the purity is 99.99%, the net weight is 50 grams, in the old times, such a small gold bar can be sold for a price of one or two hundred thousand yuan.

The bars contain only the name of the issuing bank, weight, purity, and a number, but nothing else.
