Instead of all kinds of experimental equipment like the upper ones, there are metal cages of different sizes, and most importantly, the doors of all the cages are now wide open, and the animals inside are gone.

The air quality here is not very good, in addition to a foul smell of sourness, there is a foul smell of various feces, and if you listen closely, the strange barking sounds of some animals can be faintly heard from the depths of the floor.

"Meow! Whew......"

As soon as the soldiers set up their defensive formation, they heard several terrible cries, and then a large group of animals that Li Nan once loved very much appeared.

They were a group of cats, or rather, a group of cats, and these small creatures, which used to be furry and unusually cute, were now neither stuffy nor cute.

Zombie them, hair and skin have been shed, blood-red muscles and white fascia are exposed on the surface of the body, and the fangs and claws that have been strengthened after mutation are very aggressive, looking not only ugly but also very vicious.

At this moment, these hordes of zombie cats, with blood-red eyes and saliva dripping from their mouths, slowly approached the team.

Li Nan, who has enhanced the speed of cats, knows a lot about the speed of this animal's movements, and if a normal soldier with a gun is approached by a zombie cat, according to his speed and reflexes, then he is definitely no match for these little things.

Therefore, without waiting for the seventy or eighty zombie cats to continue to approach, Li Nan hurriedly shouted: "Don't let them get close, fire immediately!" ”

After the gunshots rang out, these zombie cats quickly followed the strange route and quickly pounced on Li Nan and those soldiers who were defending at the door.

Since they have been zombied, they will not die as long as they are not hit in the head, and due to their small size, it becomes very difficult for soldiers to shoot.

In just a few seconds, several zombie cats were the first to rush through the dense barrage, and they began to swing their claws at the outermost part of the position, and their long sharp claws pierced the soldiers' combat uniforms.

Li Nan strode forward, and his military booted foot kicked out in a row, kicking several zombie cats away, although his movements were fast, but three soldiers were still infected by the cat's claw scratches.

"Throw grenades!" Chris yelled as he aimed at the three soldiers who were about to become zombies after being infected, blowing their heads out.

Area-of-effect grenades are very effective against these nimble zombie cats, and can blow their tiny bodies to shreds even if they don't blow their heads.

After three or four minutes, they finally killed all the zombie cats, and before everyone could breathe, a group of zombie dogs appeared......

Since Li Nan and the others stepped on the forty-fifth floor, the attacks of batches of zombie animals have not stopped.

Seventy or eighty zombie cats, more than thirty zombie dogs, hundreds of zombie rats, five or six zombie sheep with sharp horns, more than a dozen zombie rabbits that can jump seven or eight meters away, and two monkeys who are good at climbing......

Li Nan used all his strength to swing the beam saber and slashed the head of the African zombie elephant in front of him, and then he jumped off the giant monster with a height of three meters at the shoulder, and this behemoth, which had lost its head and weighed seven tons, finally fell to the ground with a bang.

After an hour and a half of desperate fighting, the defensive position formed by everyone was full of shredded flesh of zombie animals, and the number of dead soldiers was as high as forty-eight, most of them were killed by the zombie rat swarm and the giant zombie elephant that appeared at the end.

"Oh, F**K! It's finally over! Exhausted, Parker dropped the heavy machine gun in his arms and groaned and lay on the blood-stained floor.

Chris commanded several soldiers to remove the corpses of several soldiers who had been worn on the three-and-a-half-meter sharp tusks of the zombie elephant, and then went to check on the other soldiers.

Li Nan put away the beam saber, sat down and rested against the wall out of breath, saw Chris coming over, and hurriedly asked, "Is the soldiers' ammunition reserve still enough?" ”

Chris nodded: "Everyone set off with excess ammunition, so this is not a problem for the time being, but now we have only explored the forty-fifth floor, and more than forty people have been killed here, and I am a little worried......"

Looking at the corpses of several rows of soldiers on the ground, Li Nan said gloomily: "I know what you're worried about, but let's let everyone rest and eat something first." ”

After the soldiers finished eating, they all took the time to lie down on the ground and rest.

Li Nan called Quint and Duchenne and a few armor guards, and instructed: "There should be no danger on this floor, you go and look for the entrance to the next floor, and after you find it, don't act rashly, notify me immediately." ”

Quint and the others were ordered to leave, and their news came on the walkie-talkie more than ten minutes later.

Li Nan let the others continue to rest, and took Chris to the side of Quint and the others.

After opening the sturdy alloy gate, there is a downward corridor, and after walking a short distance, another gate of the same material appears in front of everyone.

After receiving Li Nan's signal, Quint connected the computer to the electronic lock on the wall, and after quickly cracking the code, he opened the solid door to the forty-sixth floor.

Quietly hiding in the doorway, after observing the layout of this floor, everyone gasped.

The furnishings on this floor are similar to the previous floor, and it should still be an animal feeding area, but after seeing some feathers falling from the cage, everyone guessed that this should be an area for raising birds.

Since the sound of opening the door just now was not small, there were already some strange movements in the distance, and Li Nan hurriedly said to Quint: "Lock the door immediately!" ”

As soon as the words fell, a flock of mutated zombie birds flew towards this side at a very fast speed, Li Nan, Chris and others hurriedly raised their electromagnetic guns, bursting the sharp-tailed swifts flying at the front of the flock of birds, and the rest of the birds crackled and crashed into the alloy gate that had been closed.

Worried, Li Nan and Chris led people back to the upper floor, and then called the rest of the elite team over, and everyone began to discuss countermeasures.

After listening to Li Nan and Chris's descriptions, the rest of the elite team all had bitter expressions on their faces.

This layer dealt with animals that could only walk, and more than forty soldiers were killed, if you continue to break into the next layer, you will face a large number of flying zombie birds, it is certain that these flying birds and zombies will definitely bring more damage to the team.

Since the task has been completed, and I don't want to lose too much, no one has any good ideas for this kind of problem, and everyone thinks about it with a sad face.

The atmosphere was a bit dreary, and Pierce, who was good at long-range sniping, complained: "It's all to blame for this damn new Ambrera company, we have to get the building underground, if this is a normal building, then we can go through the window and bypass these dangerous floors." ”

"Windows? Bypass? ”

Repeating Pierce's words, a vague idea gradually appeared in Li Nan's mind.
