In fact, many of the test subjects in this underground research institute were once humans, but later fell victim to the new empire's "Doomsday Apocalypse" plan, and have since become hideous and terrifying-looking monsters, trapped in this dark abandoned research institute for many years.

Big fish eat small fish, small fish eat shrimp, and shrimp eat silt, -- the underground research institute with a closed environment has formed a rather monotonous food chain, that is, the high-level experimental subjects will prey on the low-level experimental subjects, while the low-level experimental subjects rely on nutrient solutions to sustain their lives and reproduce.

As low-level test subjects, the "B1" test subjects had to use the narrow and oppressive ventilation ducts as their nests, but fortunately, their leader was quite wise, and under his leadership, the large number of "B1" test subjects was placed under the ring feeding of various high-level test subjects, and although the population size was reduced again and again, it never died out.

The wisdom of the leader of the "B1" type test subject lies in the ten words "do not choke hard stubble, and pinch soft persimmons", in short, it knows how to judge the situation, and it has a much stronger thinking ability than ordinary "B1" type test subjects, so from a certain point of view, it probably belongs to a special reinforced subspecies of test subjects.

So when he realized that the little girl in front of him who was comparing himself was not easy to mess with, the leader of the "B1" type test subject who led the entire race did not give the order to attack for a long time, and it was cautiously observing and weighing it repeatedly.

If it ordered to carry out a front and rear attack, the large number of "B1" type test subjects would definitely not be able to withstand the turtledove and the insect in this environment, not to mention that the turtledove at this time was deeply affected by claustrophobia and almost lost all combat ability.

But the rabbit bites when it is in a hurry, and the leader of the "B1" test subject has seen both "guns" and "bullets", and he has deeply experienced the feeling of being shot by bullets, in fact, in the original turmoil, the leader of the "B1" test subject has been shot several times by the New Imperial Army, and although the wounds have long since healed, those bullets still remain in his body, and from time to time he still has a dull pain.

This little girl has a gun in her hand, and it's still quite powerful.

Eyes roaming over the assault rifle in the worm's hand, the leader of the "B1" test subject blinked his small eyes, knowing that once the two sides fought each other, they would face the other party's desperate counterattack while destroying each other, so the environment that was originally favorable to the "B1" test subjects was now less favorable.

With such a narrow ventilation duct, no matter how nimble the "B1" test subjects were, how could they dodge the bullets in such a situation, and if a few more of their men ate the guns, the leader of the "B1" test subjects would not have to cry blind.

Originally, the "B1" type test subjects were just surviving in the cracks of other high-level test subjects, and they had finally survived until now, and the loss of any member was quite huge for them.

The leader of the "B1" type test subjects was hesitating, and the little worm opposite it was also hesitating, and of course the little insect knew that she could not get these test subjects on her own, so now she and this group of "B1" test subjects were like wolves with a stick.

What should I do, is the two sides so deadlocked?

……

After about a few minutes, behind the worm, a "B1" subject quietly moved forward, and it seemed that the "B1" subjects had finally decided to take the risk.

The "B1" type test subject with the absolute advantage will definitely not give up, and the leader gave a glance, and the "B1" type test subject on the other side is ready to launch a surprise attack, and the one with the highest position among them has long been unable to suppress the impulse in his heart, showing his sharp fangs.

"Bang!"

Almost at the moment when the "B1" test subject bared its teeth, the little worm still held the assault rifle in his left hand, pointed at the leader of the "B1" type test subject in front of him, and then pulled out the revolver that had just been inserted into the holster with his right hand, turned around, and accurately hit the test subject in an attack stance, the bullet penetrated the back of its mouth, and disappeared into the distance of the pipe, and it was a long time before a series of light sounds of "Dang Dang" were heard.

That's the sound of a bullet hitting the wall of a pipe and eventually falling.

With her excellent marksmanship, the insect shocked the scene at the moment before the "B1" type test subject decided to break out, and her strong momentum steadily suppressed the opponent's head, squinting her eyes, and the expression of the insect seemed to say:

"If you have a kind, you can take it a step further and try it."

Except for the "B1" test subject who was shot at the beginning, who was constantly wailing in a low voice, and now there is another "B1" test subject whose throat has been broken and can't even howl sound, both of them roll on the ground in pain, and the rest of the test subjects all step back in unison, for fear that they have inadvertently crossed the invisible line of life and death.

In order not to let the situation get out of control, the worm continued to shoot after shocking all the "B1" test subjects, and the "B1" test subjects seemed to be really frightened by the bugs, and they all looked at their leader one by one, not knowing what to do.

……

Suddenly, the atmosphere became eerie.

The little worm didn't know why she felt this way, she just had a vague premonition that something terrible would happen next, and then looking at the expressions of the "B1" type test subjects before and after, they were all like the little bugs, looking left and right with a little panic, as if they had noticed something.

All eyes were focused on the "B1" test subject who had been shot in the throat, and even the turtledove, which was about to lose its breath, stared at it without blinking.

I saw that this "B1" type test subject was pierced through the throat by a small worm, but only the trachea was destroyed, and the major artery in the neck was still fine, so it could not die for a while, it kept struggling there, and its body kept hitting the wall of the pipe due to pain, making a burst of sounds.

The people next to it watched in confusion as it struggled, squirming towards the far end of the pipe, and suddenly, the ventilation duct under the "B1" subject was suddenly distorted by something.

Silent.

Not only were the "B1" subjects stunned, but the Bug and the Turtledove didn't expect such a thing to happen, and they stared at the distorted pipe wall in a daze, and the turtledove had forgotten about his claustrophobia.
