The "B5" subspecies of the Hidden Enhancement Subject, which not only has the unique ability to blend in with its surroundings as a chameleon, but also looks similar to that of a chameleon, with a small ear hole on the left and right of the same as a chameleon in the usual sense.

Lizard ears don't look the same as humans, because they don't have the pinna like humans, but the lizard's eardrum is inverted, and it actually has the rudiments of the external ear canal, which provides the lizard with a keen sense of hearing, but it also has a small weakness.

The brain of any living thing is fragile, and if the brain is damaged, it is bound to be fatal for any living being.

Just as the "B5" subject was clinging to the wall and moving forward, trying to see what the red dot was not far away, a small black dot was already clinging to the ceiling on the other side, silently approaching it from the side.

In fact, both of them are small spider-type robots, but one of them deliberately lights up to attract the attention of the "B5" test subject, and the other small spider-type robot takes the opportunity to complete the task.

What is their mission? Of course, this was done without being noticed by other subjects, and the "B5" test subject was killed.

Subject "B5" poked his head forward and slowly moved forward, not noticing that a small object had climbed up his body, and then quickly crawled towards the back of his head, quickly burrowing into the ear of subject "B5".

"Didi, Didi."

Three soft noises indicate that the trumpet spider-type robot has successfully activated the self-detonation program, and it is only at this moment that the "B5" type test subject realizes that it has something in its ears, but at this time it realizes that it is a little too late, and it does not even hum, it convulses violently twice, and finally falls off the wall with a "snap".

The ear piercings were constantly oozing a mixture of blood and brain, and the limp corpse of the "B5" subject could no longer maintain its camouflage, only to see its skin suddenly change color twice, and finally freeze on the "B5" subject's innate dark green.

At this point, a good "B5" type test subject died in such an unknown way.

……

The power of the small spider-type robot's self-detonation is actually not too great, so the movement it emits is quite slight, and if you don't pay attention, you can't even hear the sound of its explosion, but the sound of the "B5" test subject falling from the wall is quite loud.

As a result, the iron door at the entrance to the quarantine area opened a larger gap, and several ordinary "B1" test subjects sprang out of it, and these guys who liked to live in the ventilation ducts seemed to have become the subordinates of the master.

The "B1" type test subjects are also known as creepers, and their perception ability is far inferior to that of the "B5" type test subjects, but these creepers are not deaf, and there is a "pop" sound outside, so they naturally want to come out to see the situation, and as a result, they can see the corpse of the "B5" type test subject paralyzed on the ground at a glance.

There were no obvious external injuries, and the four or five "B1" test subjects were a little confused, they looked at me, I looked at you, and they didn't know what to do for a while, and finally the leader who was the largest of them all, glared at the closest "B1" test subject, and the hapless creeper had to follow the leader's instructions and go over to check the corpse of the "B5" test subject.

"Smack."

The "B1" subject had just taken two steps forward, and it was poking its head out to observe the corpse of the "B5" subject on the ground, and suddenly, the "B1" subject was as if it had been electrocuted, and its body twitched violently twice, and then it fell straight to the ground, and a line of blood flowed from the ear hole.

The inexplicable death of the "B1" type test subject frightened the other test subjects, and the two "B1" test subjects who originally wanted to go over to see it also rushed behind the leader in a panic, and the probe probed brain, but did not dare to approach the two corpses in front of him.

……

"Otherwise, wouldn't you just give them a grenade, why waste so much time, these are just small characters, let's kill them quickly, the entrance to the quarantine area is just in front of you."

At the corner of the passage, the turtle dove and the little insect squatted hundreds of meters away from the entrance, looking at the little insect next to him who kept fiddling with something, the turtle dove couldn't help but complain to her, - obviously the front is the entrance to the quarantine area, the little insect and himself can go straight in, there is no need to delay the work here.

"Don't talk."

The worm glanced at the turtledove and immediately shut it up.

Squatting on the ground, the little insect is putting a control board larger than a palm on his lap, this thing looks like a piece of glass, transparent and transparent, but it can control the various actions of a large group of spider-type robots, as for how exactly it did this, anyway, turtledove does not understand.

No way, Turtledove had never been exposed to such a "high-tech product" before. ”

The two of them squatted on the ground for a long time, and at first the little worm would tell the turtledove some of the information she had learned through the spider robots, but later, the little worm was only focused on controlling the spider robots, and gradually lost the heart to talk to the turtledove, and the turtledove began to feel a little bored.

Not long ago, the turtledove and the insect passed through a trap laid by an octopus monster and managed to find and enter the so-called "robot warehouse", which was full of unused robots, and there were many types, and the most common ones were low-level cleaning robots.

Worm didn't look at the cleaning robots much, she led the turtledove around the robot warehouse, and soon came to the small compartment dedicated to storing spider-type robots, although opening the door of the cubicle requires a password, but Sonny had already told Worm the password before, so it was not a problem.

“9527。”

After entering the password, the door of the compartment opened, looking at the three models of spider-type robots, the worm followed Sonny's instructions, first found the transparent control board that was stored separately, entered the activation code, and after a short period of research, the worm roughly mastered the method of using the control board.

Quite simply, just like a wireless communication device, as long as the spider robot and the control board are set to the same signal frequency, then the control board can control all spider robots with the same signal frequency within the signal range, no matter what type of spider robot it is.

The previous two small spider-type robots that killed one "B5" test subject and the other "B1" test subject were controlled by small insects.
