"Boom!" After the grenade exploded, a red mist rose all of a sudden, and a thin mist enveloped the two force IV, but the two force IV did not react at all and continued to tear down the wall.

"It's useless!" Meng Soul looked at Liu Yun suspiciously.

"Wait and see what happens." In fact, Liu Yun is also a little bottomless in his heart, doing experiments in the laboratory and actual combat on the battlefield are fundamentally two concepts, so Liu Yun can only let Meng Soul wait.

Meng Soul suddenly saw that the mist seemed to be alive, and a trace slipped in from the mouth and nose of Force IV, and after about ten minutes, there was no trace of mist left, but those two Force IV were still tearing down the wall there.

Looking at Meng Soul's puzzled eyes, Liu Yun's face couldn't hold back, originally she had high hopes for this thing, the laboratory has always been the best treated department in the entire base, Meng Soul's requirements for them are basically fully met, and the required instruments Meng Soul will even personally lead the team to find them, the food supplies are all the best, and no one even bothered them during the preparation period, creating the best scientific research environment for them.

When Force IV demolished the wall, they took out this thing they had high hopes for, hoping to contribute to the base, but they didn't expect that these Force IV didn't care at all, and it didn't show any use at all.

Before Liu Yun could speak, Meng Soul suddenly found that the force IV action below had become a little sluggish, this change was not very obvious, but Meng Soul, who had been observing, found out.

Meng Soul took out a grenade and threw it down, and with a bang, Force IV was still unscathed, but Meng Soul found that many shrapnel in the grenades were directly embedded in the black scale armor of Force IV, and he knew how hard these scale armor was, and now that the shrapnel of the grenade could be embedded in it, it showed that Liu Yun's things were useful.

"Wait a minute!" After Meng Soul finished speaking, he hurriedly ran to Instructor Ling's side and said, "Instructor Ling, you can hit the force IV with a small wound on the head below, just use an armor-piercing bullet." ”

"Bang!" A large-caliber bullet hit the force IV, and the bullet pierced through the scale armor and stuck in the skin.

"It works! Keep shooting! Meng Soul clenched his fists and said excitedly.

Soon, the two Force IVs shrouded in red mist were taken care of by a large number of heavy machine guns, and the Force IV, which was supposed to be invulnerable, now accepted all the bullets as ordered, although the rifle was not good, but the 12.7mm heavy machine gun bullets were effective, and the two Force IVs were beaten like hedgehogs.

"Phew!" The two rockets accurately hit Force IV's chest, and the scales and skin on Force IV's chest were directly peeled off, revealing the black sternum inside.

Seeing that there is an effect, these two force IV are focused on taking care of, the rocket flies like rain like two corpses, and when the dust settles, the two force IV is no longer human, basically the scale armor and skin muscles all over the body are falling to the ground, although there is no problem with the bones, but the muscles on the body are knocked off a lot, and the force IV still can't stand, and the two force IV that looks like skeletons are struggling on the ground, making everyone feel as if they have seen the skeleton warriors under the necromancer.

These two force IV can no longer cause damage to the wall, looking at the two remaining silver balls Meng Soul is extremely excited, although this thing can't directly melt off force IV, but it can make force IV's originally invulnerable skin and scale armor soften, as long as the firepower is enough, it can be extinguished.

This kind of thing Liu Yun and they call it dissolving mist, but the existing materials are not enough to make more dissolved mist again, so that Meng Soul wants to use it for large-scale delivery and become a luxury.

The sky is getting dark, and the searchlights on the wall are also lit up one after another, and the remaining four force IV killed three with two silver balls, and one is too far away from the others, and there is nothing at all, and this red mist is simply terrible to other zombies, a trace of red mist can make an ordinary zombie seem to see the candle of the fire, and it is directly melted on the ground into a puddle of black liquid.

The higher the evolution level of the zombie, the less effective this thing is, and the zombies above the second type can only soften the body tissues and cannot let them melt, but in this way, the zombie's defense is greatly reduced, and it becomes easier to kill.

However, the laboratory only made these three, and it was already very happy that Meng Soul could destroy five force IVs, otherwise Meng Soul would only have to risk letting Type 99 be dispatched.

At that time, the ghost knows if it will directly fold the Type 99 outside, and the ghost outside knows if there are any big-headed zombies mixed in, in case it controls the members of the Type 99 and lets them bomb the wall, then it will really be over.

It was completely dark, and it was another whole day of fighting, the people on the wall had changed, and the zombies were killing more and more, and that force IV made Meng Soul use three red arrows 12 to blow it up, and Meng Soul could already feel that the zombies were a little powerless, but so far no one knew what the zombie commander looked like.

It was getting darker and darker, and the walls were brightly lit, but there were also places where the lights could not shine, and in a dark corner, a black figure climbed up from the wall.

The black shadow lowered his body and walked forward slowly, the black shadow was very fast, flickering and moving in the black shadow, and no one could see clearly.

The black shadow touched a soldier's resting place and lowered his body to accumulate strength, making an attack gesture, and then the black shadow jumped at a soldier who was sleeping, and the sharp claws penetrated the soldier's neck at once, and the soldier was grabbed and broke his trachea, and the blood poured directly into his throat.

"Cluck......" The soldier made a faint sound, almost inaudible in the sound of the gunshot, and the black shadow threw away the corpse in his hand, constantly jumping back and forth in the sleeping soldier, and one by one the fresh lives disappeared in its hands.

A team of fifteen people was killed by it one by one, and then touched the other team, and the soldiers who were stabbed to death by it behind it staggered to their feet, and their blue-gray skin all showed that they had been degenerated......

The zombies were spotted as soon as they stood up.

"There's a zombie coming up!" Several soldiers drew the light of the searchlight with a loud voice, and the black shadow was exposed to the light.

The black shadow was a little uneasy under the searchlight, and then all the soldiers felt a flower in front of them, and the black shadow brought out the afterimage and pounced on the soldier who was controlling the searchlight.

"Be careful! It's an agile zombie! It could be Min V! ”

Meng Soul reacted as soon as the riot just started, and was startled when he saw the black shadow Meng Soul, he had never seen an agile zombie of this speed, and this zombie was actually wearing a cloak, if it weren't for the fact that it ran in the same way as an agile zombie, Meng Soul would think that he had seen a speed-type new human.
