"Watch the back!"

Qi Lin shouted, he had already seen several humanoid monsters pounce from behind Cheng Yanqiu!

Cheng Yanqiu hurriedly turned around, retreated, and then pulled the trigger, and the fire from the muzzle of the gun instantly illuminated the dark tunnel, and with the sound of gunshots and screams, those monsters fell to the ground one after another.

"This should have been tailgating after we entered the tunnel." Qi Lin stepped forward and looked through the corpses, which were obviously the same kind of creatures as the guy who hung at the top of the tunnel before.

"Their strength is not very strong, their defense is almost zero, and a nine-millimeter pistol bullet can easily penetrate the bodies of these guys." Cheng Yanqiu continued.

"That's the best, I don't want to face a thick-skinned guy like a parasite." Qi Lin glanced at the corpse in the tunnel a few times and continued to walk forward.

These monsters were once human, and their fate was even more tragic than that of those who were able to enter the shelter - they did not die in wars and disasters, but were killed as monsters by their former kind.

But then again, for them, maybe death is a relief.

The two walked along the tunnel for about a kilometer, and finally found the place where the tunnel was connected to the old subway.

Cheng Yanqiu walked to the waiting platform and wiped off the thick layer of dust and stains on the station sign.

"This is the 'Yumin New Village' station, three kilometers to the south, is the 'Century Commercial Building' station, which is the large underground shopping mall I mentioned earlier, and the passage to another stronghold is in this abandoned shopping mall."

"Three kilometers, not too far."

Three kilometers is indeed not too far, if you run at full speed, Qi Lin only needs a little more than five minutes to run, but the question is whether there will be any obstacles on the road of these three kilometers, or rather, whether there are any monsters.

If it's still something like a humanoid monster, it's easy to deal with, if it's an electric drill, then it may be a little trickier, I'm afraid that there is a guy above D level on this road, then Qi Lin can only turn around and run away when he sees it.

Although the level of a third-level evolutionary just corresponds to the level of a D-class mutant creature, this correspondence means that to reach level 3, you need to absorb at least one D-class mutant serum to advance, not that the strength of a third-level evolutionary is on the same level as that of a D-class mutant creature.

Just like in the game, Qi Lin's evolution level is level five, but he is still not the opponent of the B-level King Blood Dragon Lizard.

Of course, this does not mean that humans must not be able to defeat mutant creatures of the same level, after all, the reason why humans can become the masters of the earth has always been not by their fangs and claws, but by their brains.

It's just that now Qi Lin doesn't have power armor and heavy weapons in his hands, not even a large-caliber rifle, only a hollow steel pipe, which is like letting a human in a primitive society take a stone to fight a saber-toothed tiger hand-to-hand, and the consequences can be imagined.

As for Shi Nai'an's "Wu Song" who beat the tiger with his bare hands, although there is indeed this character in history, but the "tiger" that people fight is a second-generation official nicknamed "Cai Hu", this person's original name is Cai Jun, in the fish and meat township, he did all kinds of evil, and was assassinated with a short knife by Wu Song, who was determined to eliminate harm for the people.

……

Qi Lin returned the two magazines to Cheng Yanqiu, Cheng Yanqiu's hand-to-hand combat ability was not as strong as Qi Lin's, and he had almost wiped out that bullet in the tunnel just now, with that small folding knife, I am afraid that even an electric drill bit would be a little difficult to deal with.

As he walked, Qi Lin suddenly stopped, took off his breathing mask, and took two deep breaths hard.

"It stinks, it smells bad, it's not normal."

The subway tunnel was not ventilated, but it was clean, and there were no corpses piled up in large numbers except for garbage, and there were no special plants that would emit a stench, so there was only one possibility - the smell was from some mutated creature.

It's not uncommon to use a pungent body odor to mark your territory.

Cheng Yanqiu also took off his breathing mask, tried to take a breath, and immediately coughed violently.

"The smell ...... It's just breathtaking......"

"There's not a lot of oxygen in the air here, and you'd be suffocated without the smell." Qi Lin complained casually, lifted the steel pipe, maintained a posture that could be thrown at any time, and cautiously walked forward.

The structure of the subway is very strong, there are no landslides or faults, and you can use your feet to push away the layer of dust that covers the ground, and you can even see the tiled floor underneath, which is still relatively clean.

"Did you find anything?" Cheng Yanqiu's dark vision obtained by relying on drugs is much worse than Qi Lin's, in a lightless environment, Qi Lin's vision can be seen about two hundred meters at most, while Cheng Yanqiu can only see things within fifty meters, and things that are a little farther away seem to him to be a bunch of blurry black shadows.

"Haven't seen anything yet." Qi Lin shook his head, leaned against the edge of the subway tunnel, and continued to touch forward.

Human corpses began to appear in the subway, a dried corpse fell to the ground horizontally, from their clothing can be seen that these people lived in good conditions before their deaths, a female corpse closest to Qi Lin was wearing a graceful fur coat, and the handbag in her hand was a "GUCCI" bronzing logo.

These people were once middle-class people in the big cities, but the sudden war had reduced their money to waste, the balances in their bank accounts to meaningless figures, and they couldn't even grab a bed in a shelter slum.

In the early days of nuclear war, subways, basements, and bomb shelters were the most evacuated places, and the sturdy underground structures did allow them to escape the first few rounds of bombing and subsequent radiation, but the shortage of supplies became the biggest problem.

No one wanted to go to the ground covered in cold and radiation, and the little food and water that little was quickly consumed, and then came the most chaotic time.

Robbery, murder and other incidents broke out frequently, and the hungry and panicked people even began to eat the corpses of their own kind, the strong men took the lead, the children and the old and weak were almost all killed, and the women left some young and beautiful ones as tools to vent their desires, and the rest became food.

Unlike in the vault, there is no system, no law...... Again, there is no hope.
