After Zuo Zhan crushed the monster's head, a wave of vibrations appeared, and one by one the petri dishes were slowly opened. Le-Wen

Countless cultures were poured directly on the ground, one by one the experimental subjects fell to the ground, and after a while, all the petri dishes were opened, and the creatures that didn't know what they were slowly moved, Zuo Zhan watched these things that didn't know what they were slowly stretching their bodies.

A monster raised its head and rushed to the left without hesitation, and because of the actions of this creature, other creatures also rushed to the left to fight together.

Zuo Zhan solved the first petri dish with one kick, but there were so many of these things that Zuo Zhan was a little surprised.

"There should be two thousand...... Zuo Zhan counted the number of these creatures slightly, and this number was almost the same as the troops of the Seventh Research Institute.

"It's not two thousand, it should be three thousand four hundred and fifty-five to be exact, plus the two you just solved a total of three thousand four hundred and fifty-seven, this is the number of test subjects in this layer, your opponent is them, their name is Chimera." The voice looked at Zuo Zhan here and said, this layer doesn't know where the sound came from, but this kind of subconsciously smashed that area with a knife.

Left Fight confronts this group of creatures who don't know what it is. Without the slightest hesitation, rushed towards them, since the combat power of this floor is here, let's deal with them here at once, anyway, these creatures no longer have the basic characteristics of a human, let's let them disappear here.

Almost all of a sudden, Zuo Zhan's knife was already stained with layers of dark red blood, this was a real flesh mill, Zuo Zhan could cut a Chimera in half with a casual swing, but just a fraction of a second, more Chimera rushed up.

Zuo Zhan began to use the shadow ability to dodge those Chimera's attacks, sneak into the shadows and use shadow warriors to fight, but for this number of enemies, the shadow warriors are too few, almost one after another Chimera are eliminated, although the combat power of these Chimera is not very powerful, but for those ordinary people, ordinary people, their physical fitness is still very good, and they can easily lift more than 5,000 catties of things, but it is still not enough for Zuo Zhan, Fighting here, as long as the left is not careful, there is no possibility of defeat.

The battle of Zuo Zhan here is basically to solve one with one sword, but there are too many enemies here, even if they are weak for this kind of thing, solving them all is a great consumption of Zuo Zhan's great physical strength, and there is no difference between exhausting physical strength here and dying here.

The left battle slashed one by one, but the number of Chimeras around them was still not much less.

Suddenly, two powerful kingly spirits stunned most of these Chimeras through the floors, and some of the more powerful Chimeras were not stunned, but they were also stunned for a few seconds, and it was these few seconds that this kind of unhesitating use of large-scale shadow Feiyan to kill these Chimeras who had not yet been stunned.

Zuo Zhan saw that the Chimera who could not continue to stand, walked to the stairs on the next floor, directly destroyed the stairs there, and jumped down directly.

"It seems that those Chimeras can't deal with you, so let's see if the Chimera on this level can get into your eyes? This layer of Chimera is made by your compatriots, and all of them have the ability to mutate. I don't know where the voice came from, but I still sold some information to Zuo Zhan as arrogantly as ever.

Zuo Zhan didn't pay any attention to the voice, just picked up his knife and sneaked into the shadows, rushed out of the stairwell, and reached the sixteenth floor.

As soon as Zuo Zhan rushed here, he could clearly see a group of mutant Chimera who had completely changed their appearance appear here, this is the third place in the most core area of the Seventh Research Institute, and it is also the layer of the most mutant Chimera, theoretically the strongest layer.

Zuo Zhan saw that those people were only sluggish for a second, and he had a strange ability to attack Zuo Zhan.

"This is ......" Zuo Zhan felt that he could no longer continue to sneak in the shadows, and was forced to appear on the ground, and as soon as Zuo Zhan appeared, he was immediately attacked by several energy bombs.

Zuo Zhan used his knife to stop, used the power of the knife to jump into the sky, and sent out several knives in a row to detonate the energy bomb that came to his face.

Zuo Zhan opened his hands and directly borrowed the shock wave of the explosion to enter the shadows, but immediately after that, several flares flew into the shadows, illuminating Zuo Zhan's figure at a glance.

Zuo Zhan picked up a few wooden thorns at once, swung a knife in the direction where the wooden thorns came from, and then quickly approached another dark place, but this time it was not just a matter of a few flash grenades, dozens of missiles flew to Zuo Zhan in a row, this is a spider magnetic storm missile, or a missile with very good tracking performance.

Zuo Zhan kept dodging left and right, but the missiles still kept following Zuo Zhan, he had to detonate those missiles with a continuous knife, and for a while, shrapnel flew everywhere here, making a burst of musical instrument sounds on the walls here, and the explosion of missiles had cleared the space here.

Zuo Zhan knocked a Chimera who attacked him from behind into the air, and the other variants of the Chimera released dozens of flashbangs in a row, covering the entire sixteenth underground floor, and now several flashbangs in a row have illuminated everything in this level clearly. There is no place to hide here, and all that remains is a head-to-head showdown, with a left battle against the eighty-three variants of the Chimera.

Eighty-three mutant Chimera is eighty-three only with the fighting instinct of animals, the talent for fighting, and the infinite possibilities of human biological weapons, except for the shortcoming that is difficult to control, the others are very obtainable, each of them has at least two abilities, it may be a mutant ability or it may be due to the effect of machinery, each of them will not lose to the lieutenant colonel in combat effectiveness, and several have the strength of a brigadier general.

Zuo Zhan looked at the mutant Chimera here for only a few seconds and already knew the general combat ability of the mutant Chimera here, these together are not something that the current Zuo Zhan can easily defeat, and now Zuo Zhan already knows very well what the person behind the scenes wants to do, his purpose is to delay time and consume his physical strength, but Zuo Zhan has no good way to deal with these mutant Chimera in the face of this situation.

"It seems that you have to struggle here for a long time, so I'd better deal with those two people first!" The voice came out of nowhere
