death to survive

Finally, in this labyrinth-like corridor of the research institute, they found a staircase leading to the upper floor. Along the way, they could constantly see the torn and bitten stumps of human beings and the ground wall. The blood splattered on the face, and the footprints that had been stepped on the blood and rubbed on the white floor tiles were all strangely shaped imprints, big or small, and it was unknown what kind of experimental subjects attacked those people.

However, those scorpion spiders have all gone out of the forest, and the other experimental subjects are probably running about the same now, except for some lazy ones who are unwilling to go far, and those who prefer meat, they are still guarding the research institute, attacking and gnawing Eat those soldiers who were sent in and the rest of the staff who were not infected and hid in the research institute.

"Damn it! Is there no living person here?" Wang Yang couldn't help complaining as he stepped over a human corpse that had been devoured and only had a skeleton left on the stairs.

"Except for the crazy soldier we met at the beginning, it seems that we haven't seen anything alive..." Qiao Feiyu said that it is true that until they came in now, the other humans they saw were all dead.

"I don't know what's going on here, it's so chaotic, there are aliens and experimental subjects, and a bunch of soldiers who came here out of nowhere, we really didn't come at the right time, Xiao Yi, don't you think so?"

He bumped Xiao Yi's arm with his elbow, and Wang Yang sighed.

"If you don't come, you can't get the neutralizer..."

"Uh... well, everyone is still dragged down by me..." The topic went around and around, and finally turned to Wang Yang himself. Where to climb to finally find it.

Stepping on the last step of the stairs, looking up, you can see the decoration of this floor, which is as white as the floor downstairs!The style of the people is different. The color of the entire floor has been painted dark gray, and the floor is also covered with black marble floor tiles. The overall look feels a bit depressing and dull.

On this floor, like the one below, there is no one around. Everyone's shoes are stepping on the silent corridor of the research institute, and only the sound of their footsteps can be heard. .

A few people were walking, as if they had come to a huge hall. Looking up, they felt that the ceiling was extending upwards, with no end in sight.Wang Yang looked up at the pitch-black roof where he couldn't see where the roof was, and asked Xiao Yi: "How can it be built so high inside the research institute? It doesn't seem to be visible from the outside."

"This is in the middle of the mountain."

"Ah? Mountain?" Wang Yang tilted his head and thought for a while. He seemed to recall the gourd-shaped mountain behind the research institute, and he couldn't help but exclaimed: "The research institute has extended into this mountain? Cool !Then we are standing in the middle of the mountain now?"

"Correct."

"This architectural design is really special." He also raised his neck and looked at Qiao Feiyu, who was at the top of the black roof. He seemed to hear some slight movements in his ears, and asked Fang Zhihong standing beside him: " Did you hear anything?"

Li You, who was getting feverish and comatose behind him, wiped the sweat from his forehead. Fang Zhihong turned his head, glanced at Qiao Feiyu, and shook his head: "What? I didn't hear it."

"I seem to have heard something just now..." Wrapping his arms around himself, Qiao Feiyu turned his head again, thinking that he was not hallucinating just now, he really seemed to have heard the sound of flapping wings.

"Winged bat..." Xiao Yi suddenly replied in a clear and deep voice.

"Ah? What is that?"

Wang Yang turned his head and looked around vigilantly. He seemed to have heard the sound of wings flapping.

"It's a low-level experimental subject, and it was originally locked in the laboratory."

"..."

Well, the other test subjects have all escaped, and it is impossible that this one did not escape... Wang Yang helped his throbbing forehead, and asked a question that he was eager to get the opposite answer: "It... likes to eat Meat?"

"Do not."

"Oh?!" Wang Yang's eyes immediately lit up with a look of hope. So, that experimental subject called what kind of bat shouldn't pose a threat to them, right?

"The winged bat is ferocious, agile, good at flying, and likes to eat blood." Like memorizing a textbook, Xiao Yi introduced the basic attributes of the winged bat without any ups and downs.

"..."

"..."

"...Damn! You finished your sentence, which made me happy for nothing." Wang Yang glared at the expressionless Xiao Yi. He heard that another dangerous creature who was interested in them was about to appear. , muttered in a depressing voice: "Is there no experimental subject in the research institute with a milder personality? XXXX! Vampire bats have come out."

"No, I think vampire bats are definitely cuter than it..." Qiao Feiyu, who took up the conversation, motioned Wang Yang to look at the inner wall of the cave at the top of them, that is, the completely dark ceiling, illuminated by the dim light in the hall. Under the reflection, Wang Yang vaguely saw the huge monster standing on the edge of the cave-shaped inner wall with its claws.

It is as big as a truck tire, and the fleshy black wings hanging down on both sides are like those of a bat. It is estimated to be fully stretched, at least two meters wide. The whole body looks like a head, and it is as tall as The facial features are very human-like, with a nose and eyes, and a protruding bloody mouth. The two blood-sucking fangs protruding from the mouth are estimated to be as long as a dagger. Let alone being blood-sucked. If you get bitten, you will lose half your life, right?

The whole head-like body is covered with brown semicircular feathers, one by one sticking to the surface of the skin like a human face, two hanging human-like eyes, but the eyeballs are surprisingly large, the whole black Its eyeballs accounted for two-thirds of the eye sockets, and under the head, there was a pair of claws that were sharper than an eagle's, firmly grasping the mountain wall, stabilizing its huge body.

This human-headed biological experiment subject with a human face and wings shook the bat wings on its back, and looked at the humans who broke into the hall with its huge black pupils that faintly reflected blue light.

When Wang Yang saw this creature, he couldn't help sighing in his heart. It is worthy of being researched by the research institute. The combination of the human part and the biological part is really full of weird horror...

Suddenly, the winged bat standing on the mountain wall stretched out its wings to both sides with a sound of "唰──", fluttered up and down twice, straightened up and flew towards Wang Yang and the others.

Wang Yang hurriedly lowered his body and brushed past the winged-headed bat flying over his head, and he could feel the wind sound of his claws just passing by at the end of his hair.

Not catching Wang Yang, the winged bat circled and glided in the air, then turned to attack Qiao Feiyu on the other side, fluttered its black bat wings, opened its sharp claws in the air, and grabbed Qiao Feiyu's body.

Qiao Feiyu quickly raised the pistol that Wang Yang gave him, aimed at the position between the eyebrows of the winged bat that was grabbing towards him, and fired a shot.

"boom!"

After a loud gunshot, the winged bat was knocked down and fell to the ground, its wings were still flapping on the ground, its body tried to turn over, and the wound shot through its head, blood was gurgling from inside. out.After tossing a few times on the ground, the winged bat froze and died.

"It's dead?"

Walking closer to the winged bat, Wang Yang wondered, this death was too smooth, right?For the few of them who are fighting against all kinds of alien monsters every day, this is the first time they have encountered such an easy-to-solve monster...

"Well, it seems to be dead." Stretching his legs, Qiao Feiyu tentatively kicked the motionless body of the winged bat on the ground, seeing no response, he affirmed.

"Cut, this wing-headed bat is really fancy but not useful..." Wang Yang curled his lips in contempt because he thought it was such a difficult experimental subject.

"Don't let your guard down, they live in groups." Seeing Wang Yang's disappointed and contemptuous look, Xiao Yi casually reminded him while standing aside.

"what?"

Wang Yang turned his head to look back at Xiao Yi, and blinked, that...doesn't mean...

"Puchi—"

"Puchi—Puchi—"

"Puchi—Puchi—Puchi—Puchi—"

The sound of countless wings beating echoed above the place where they were standing, and the inner wall of the dark cave with no roof visible. They looked up, but they couldn't see the figures in the darkness at all.Only by looking down at the ground can we see those black ghost-like shadows flashing past the ground quickly.

Everyone raised their heads immediately, staring fixedly at the top of the dark cave, not daring to look away. Although they couldn't see anything in the dark, they could hear the sound of flapping wings getting louder and louder in their ears ...
