Yang Ning and Ren Yingying walked into the corridor of Area A, it was very dark here, there was no light, and the two of them moved forward with their consciousness, because they were facing genetic mutant animals, and the two did not dare to walk fast, even if it was Yang Ning, they did not dare to be careless in the face of unknown enemies.

"You say, if these biochemical monsters are really released, what will happen to the humans?"

"Then you don't have to wait for the alien invasion, and the island nation will wipe out the human race." After Yang Ning replied, he suddenly stretched out his hand to stop Ren Yingying's forward movements, pointed to the next room with his thumb, and motioned to go in and have a look.

The two of them stood at the door with guns on guard, Yang Ning cautiously pushed the door open, it was still dark inside, but Yang Ning's eyesight could still see the situation inside.

This is a real yàn room, no, more like a specimen showroom, it is full of glassware, and the transparent potion is soaked with the carcasses of various animals, the larger ones have cheetahs, the smaller ones have spiders, and after walking around, it can be said that there is everything here.

"Were these studies successful or unsuccessful?" Ren Yingying looked at the utensils and asked.

"It should be ......" Yang Ning was also unsure, so he took a closer look, it turned out that there was an introduction under the glassware, and he read it out casually:

"In 1923, the first biochemical test specimen. Holy shit, started studying viruses so early, fuck. ”

"Didn't that start in 1923 in the First World War?" Ren Yingying asked in horror.

As soon as he thought of these things, Yang Ning's heart was very heavy, his hometown was in the northeast, the place where the island country invaded the most severely affected area, the 731 site was Yang Ning's hometown, and the hatred for the island people could be entered into the bone marrow long before he was born.

"Perhaps, when Unit 731 was in my hometown, it was this biochemical virus that was studied, hey!" Yang Ning sighed and turned around to leave, and Ren Yingying hurriedly followed.

The two walked slowly in the corridor without speaking, but after walking for about five minutes, they didn't meet a single biochemical animal.

Standing in front of a wall, Yang Ning took out a bomb from his bag, installed it on the wall and continued to move forward, but as soon as the two walked around the corner, a forked snake head suddenly spit out next to the time bomb, and after a while, a very large figure slowly climbed down from the wall and crawled towards Yang Ning's rear.

Ren Yingying and Yang Ning are still moving forward unconsciously, this real yàn room in Area A is the earliest real yàn area of this underground base, and the facilities here are very old, and there is no modern atmosphere at all. If you look at the dust deposited on the ground, you can see that it hasn't been open for at least 80 years.

Walking in the corridor, Yang Ning suddenly felt a strange feeling behind him, and hurriedly turned around to guard his gun behind him, but after observing for a long time, he didn't find any clues.

Ren Yingying was also cautiously guarding behind her, but she didn't notice anything, looked at it for a while and asked in a low voice:

"Questions?"

"Yes, I feel something, but I don't know where?" Yang Ning replied.

"You can't see it either?" Ren Yingying was shocked, of course she knew Yang Ning's ability, but even Yang Ning couldn't see the creature, was there anything to play?

"Actually, I can see living life, but zombies are considered dead people in addition to being able to move, in my consciousness, they are no different from corpses, and it is normal not to see." Yang Ning explained, carefully identified the rear, and when he confirmed that it was okay, Yang Ning turned around and walked forward.

While the two were walking, Yang Ning said:

"I can't see it, but I know it, right here!"

As soon as the words fell, Yang Ning suddenly turned around, and the gun in his hand quickly pointed at Ren Yingying, Ren Yingying was startled and hurriedly turned his head sideways, and at the same time, Yang Ning shot and shot.

"Whoosh"

The Electronic Pulse Gun fires an electric arc and hits a serpentine monster that is flying down from above.

Yang Ning really didn't see this snake just now, not even in his consciousness, but Yang Ning has his own way, he can judge the position of the object by relying on the flow of air, just when Yang Ning was on guard, the snake-like monster was hiding in the vent above his head, it didn't attack or move, Yang Ning really couldn't find it. Therefore, Yang Ning planned to take a risk, but the snake really attacked.

Yang Ning walked to the snake monster with a gun, it is not an exaggeration to say that it is a monster, this snake only has the body of a snake, about 2 meters long, but its head has completely changed, it looks like a fish head, and it looks like a lizard, in short, it has no snake characteristics.

Yang Ning smashed the snake in two with a single shot, its lower body did not move, but its upper body still writhed, and a pair of lizard eyes flipped back and forth, as if it was looking for a way out of death.

After Ren Yingying saw this monster, she grinned and said:

"Evil, it's disgusting, it's not dead?"

The snake monster seemed to understand Ren Yingying's words, its body lost its support, but its head could still speak, but when Ren Yingying's words fell, the snake suddenly opened its bloody mouth and actually tore about a meter, which frightened Ren Yingying and hurriedly retreated.

Normal snakes open their mouths up and down, this snake is good, he actually has a three-petal mouth, and the snake's jaws are also separated, and a row of dense fangs and blood hula look really disgusting.

Yang Ning didn't want to look at it anymore, so he took the gun and fired another shot at the snake's head, and after solving it, Yang Ning turned around and continued to walk, saying:

"The animals here are all mutated like this, and this snake is not very powerful."

"What kind of awesome?" Ren Yingying asked rhetorically.

"Felines."

Just as Yang Ning finished speaking, a shadow suddenly flew by in front of him, Yang Ning and Ren Yingying were both evolved physiques, but neither of them could see what this shadow was.

"My broken mouth, what do you say?" After Yang Ning scolded, he took the gun and walked cautiously with Ren Yingying.

But at this moment, the two of them heard the sound of animals eating behind them, and Ren Yingying subconsciously looked back and was immediately surprised.

"Yang Ning looks."

Yang Ning looked back and saw a monster the size of a leopard eating the snake that had just died. It is huge, its limbs are very strong, especially the two front paws, when the snake body is opened, the five fingers and claws are as sharp as a blade, but what shocked the two of them was that the cheetah's fangs and its mouth were also separated by three petals.

The cheetah monster seemed to feel that two humans were looking at it, it slowly raised its head, staring at Yang Ning and Ren Yingying with a pair of red eyes, its three-petal mouth closed, and its body moved cautiously sideways, as if it was about to attack.

"When did it come here?" Ren Yingying asked.

"I don't know, but I know it's smart, and it's not one."

"What do you mean?"

As soon as Ren Yingying asked these words, Yang Ning suddenly turned around and shot in front of her, and a black figure rushed up very quickly, Yang Ning's marksmanship was very good, but in this situation of continuous shooting, not a single shot hit the black shadow.

Ren Yingying subconsciously turned around, but Yang Ning hurriedly reminded:

"Watch out for cheetahs."

Ren Yingying reacted, but when she turned back, the cheetah, which was still far away from them before, was actually not far away from them, and looking at its speed, it was really lightning fast.

Ren Yingying hurriedly shot and shot, but the cheetah was too fast, and a few vertical jumps avoided the bullet shots, jumping back and forth on the wall, dodging all the bullets while getting closer to the two.

"Yang Ning!"

Ren Yingying couldn't kill this cheetah, and she only had time to shout when she saw the cheetah flying over.

But just when this shout fell, the cheetah had already jumped in front of Ren Yingying, ......and in the blink of an eye, the cheetah seemed to hit the invisible wall, and then fell to the ground.

Ren Yingying saw that the opportunity had come, and shot at the cheetah that fell to the ground.

"Bang"

Fortunately, the bullet finally hit the cheetah, and it wailed to flee the place, but it was injured not as fast as before, and Ren Yingying seized the opportunity to fire a few more shots until the cheetah was killed.

The battle was over, Ren Yingying looked back, the battle on Yang Ning's side was also over, just when the cheetah hit the ability enchantment, Ren Yingying heard a crash behind her, and it is estimated that these two are hanging like this.

Walk over and take a look, this black shadow is indeed in the form of a cheetah, but the fur of this cheetah has long been gone, or it is rotten, it shows disgusting internal organs, the three-petal mouth has been broken, half of the head is gone, it is still gasping, Yang Ning continued to shoot at the cheetah, until the head was broken.

"Good fellow, life is so tenacious." After Yang Ning snorted, he took out the bomb and continued to install it on the wall, looked at the map, there are still two more bombs to be installed in Area A, and I don't know how many such mutant monsters there are ahead.

When Yang Ning planted the bomb, Ren Yingying pressed the headset and seemed to be listening to something, and when Yang Ning finished installing it, Ren Yingying also finished listening, stepped forward and said:

"YNZ found a place where the biochemical virus was stored, and they asked, this is how it blows up, will the virus disperse with the air, do you want to leave the central area, and other places blow up and bury the central area."

Yang Ning thought for a while and said:

"No, let them hurry up and plant the bomb, we're running out of time, tell them to assemble in the center in the last hour."

Ren Yingying replied, Yang Ning guarded the depths of Area A with a gun, and after confirming that there was really no problem, he continued to move forward.

It's also strange to say, the mutant animals in Area A are not as casual as zombies, Yang Ning and the others walked all the way, only saw the three before, and didn't see the others, and they didn't know if they were hiding or going out.

Later, it was Athena who explained Yang Ning's doubts, animals have the habit of allocating their own territory, and in general, without extreme temptation, animals will not deliberately violate other people's territory, which is tantamount to causing war.

Yang Ning was relieved, but after installing the last bomb, Yang Ning found himself in big trouble, because this territory was a very huge mutant spider monster.
