Possessing the upright form of a "A" type test subject and some of the distinctive features of a "B" test subject, the turtle dove and the insect accidentally encountered this monster overturned the inference that the insect had just made, as it was clearly neither a "A" nor a "B" test subject.

Or vice versa, i.e., it is both a "A" and a "B" type subject.

It's such a specific unknown monster, chasing the turtledove and the worm tired, out of the kitchen of the cafeteria after panicking, all the way to the head just to escape, at this time the worm finally found that there is a ventilation pipe to drill, who knew that she got in, the turtledove was only half drilled, and the calf that was still exposed was caught by the monster.

A huge force dragged the turtledove out, and the turtledove itself also had two strengths, but he gritted his teeth and was not dragged out by the other party, he gritted his teeth and held on, and he couldn't even ask the worm to help.

It all happened between the lightning and flint, and the little insect was too busy to take care of herself, and she didn't have time to pay attention to the situation on the turtledove's side the whole time, and she hurriedly crawled deeper into the pipe, not noticing that the turtledove behind her was being dragged out.

"Help......"

The turtledove knew that if he continued like this, he would have to be dragged out by the monster, so he hardened his head and finally squeezed out three words from between his teeth, and then the whole person was dragged back by the monster violently.

The ventilation duct is not too narrow, and it can even stand up semi-straight in it with the size of a small insect, but it is more convenient to squat and walk far away than to crawl forward, at this time I heard the turtledove behind me calling for help, and the small insect turned around with difficulty and quickly crawled back.

The turtledove's strength is great, but compared to the monster, it is still a little insufficient, he is not good in the pipe at this time, after asking the worm for help, most of his body is about to be dragged out of the pipe by the monster.

Seeing this scene, the little worm knew that in this pipeline, the turtledove could not compete with the monsters outside even with its own strength, and instead of fighting with the other party, it was better to take some more dangerous methods, otherwise it would be basically difficult to save the turtledove.

"Get out of the way."

As the little worm spoke, she had already removed the assault rifle she was carrying behind her, she lay down in the pipe and took aim for a while before pulling the trigger, and several gunshots rang out, and several rifle bullets grazed the turtledove's body and shot straight into the arm of the monster outside.

At such a close distance, the turtledove's body blocked most of the insect's field of vision, even if it was a sharpshooter like the worm, it was difficult to guarantee that the muzzle of the gun would not be deflected and hit the turtledove, so her move was indeed extremely risky, and if she was not careful, it was the turtledove's head that was blown up.

Although the bullet of the assault rifle was not enough to cause effective damage to the monster, it still hurt a little when it hit its body, at least it could subconsciously shrink its hand back, feeling that the monster was forced back for a moment, the turtledove didn't care about anything else, and quickly pulled out his leg from the other party's hand, and crawled forward along the pipe.

The boiled duck flew, which is called how the monster outside could not thunder, it tried to put its claws into the ventilation duct, but it could not catch up with the speed of the turtledove to crawl forward, and it was about to touch the soles of the turtledove's feet, but its arms were so long that they could no longer reach in.

The sharp claws scratched inside the ventilation duct, and the monster reluctantly let out a roar outside, and due to the sound of the ventilation duct, the turtledoves and insects inside were so shocked that their eardrums were about to perforate, so they had to cover their ears and dare not move.

To say that the roar of this monster is indeed extraordinary, and there seems to be an indescribable sense of psychic impact in the middle, which can penetrate the body and reach the soul, otherwise they would not have been frightened by each other's roar before.

Turtledove can be remembered as if he was facing the "undefeated legend" in the abandoned city, and the "undefeated legend" with his unattractive appearance is the feeling he gave himself.

According to Schultz, it was later learned that the "Undefeated Legend" was an experimental subject who had fled the country, and he eventually turned into a terrifying tide caller, triggering a "wave of terror" that plunged the entire abandoned city into an unprecedented disaster.

In terms of appearance alone, the monster outside the ventilation duct has many similarities between the "A" type and the "B" type test subject, but now that you look at it, it seems that there are other unknown secrets on it, so this monster is definitely not simple.

"Hey, such a not simple monster, how did you let yourself run into it."

The turtledove sighed, and looked back again, the monster was too big to burrow into the ventilation duct, and was desperately banging against the wall there, but what if it knocked down the wall, the turtledove and the worm had already crawled down the ventilation duct to other places.

The worm was in front and the turtledove was behind, and the two of them crawled in the ventilation duct for five or six minutes, until they could no longer hear the sound of the monster hitting the wall, and then they found a more spacious place to stop, leaned on the side of the pipe, and rested for a while.

……

There is a vertical ladder on the wall of the pipe behind the turtledove, and there is a fan at the top, which is slowly turning, through the ventilation duct to the whole of the building, and there are several forks in the top, which should lead to other places.

Ventilation ducts are always available in all directions.

The space here was a little more spacious than before, and the little worm couldn't sit still for a while, she got up and wandered around, and suddenly as if she had made some unexpected discovery, she got into a corner in front of her without saying a word.

The turtledove didn't know what the insect had found, and his fright was settled at this time, so he quickly chased the insect and crawled over, turning his neck, just to see that the insect had removed a baffle and was drilling outside.

No matter how spacious the ventilation duct is, it will always make people feel oppressive, and the turtledove does not like this feeling very much, and he saw that the worms were all out of the way, so he also drilled out with the worms.

"What is this place?"

Turning around and looking at it for a whole week, the turtledove was confused by the huge instruments in front of him, and he didn't understand what they were for, let alone what this place was for.

"If I'm not mistaken," the little worm looked around, and had a rough idea in his heart, "This should be the control room in this area where we are now, you look at the monitor over there, the third monitor, isn't it the monster that forced us into the ventilation duct." ”
