The tunnel is surrounded by gray concrete walls, and because of the purpose, the construction is very strong and safe, and the soil layer is tightly sealed. In terms of hardness, a 5.56mm rifle bullet can only leave a notch on it that is less than the size of a fingernail. The same is true on the ground. During the journey of the armored truck from the outside to the inside, the humidity of the air in the place where it passed was not high, and it was normal humidity that ordinary people could not feel dry or wet, but after going deep into the tunnel for 800 meters, Wu Qi obviously felt that the humidity in the tunnel had increased subtly.

With Wu Qi's rich experience in the jungle, he is unusually sensitive to the smell of damp soil. Even though Wang Sheng was carefully observing a broken cave wall with a diameter of more than three meters not far away, Wu Qi didn't see it, but his skin could feel it; This dampness does not emanate from the inside of the soil at the broken wall, but gives him the same feeling of humidity in every direction.

In other words, every corner of the tunnel is not completely closed from the soil layer. The conclusion that this body instinctively came to was so absurd that Wu Qi couldn't even believe it.

In complete darkness, a small concrete wall at the top of the tunnel suddenly moved strangely, and the small area of wall soil raised slightly, and then flowed naturally in all directions. A piece of black-purple skin emerged from it, and then the more it protruded, the more the area of the soil expanded, and finally the black-purple thing broke free from it completely.

It was a strange head, the size of a human head, without eyes, with nostrils degraded to two short lines, and a very wrinkled skin that was unsightly black and purple. The mouth part occupies half of the entire skull. The monster opened its lips, revealing a bloody jaw that was extremely hideous. The dense dark red teeth with the length of a finger are shaped more like the claws of wild beasts, and there are more than one row, and there are multiple groups of teeth of inferior size in the cavity, like shark teeth, terrifying.

The monster's head came through, its tiny nose smelled the scent of the humans below, and its skin color became a natural protective color, in this dark environment, even if humans had night vision, they would never be able to detect it unless they kept staring at the top of their heads. And this is exactly the case, more than ten people at the bottom, even Wu Qi, did not perceive its existence. Its lizard-like body flowed out of the concrete walls little by little, as if it was born to swim in it without making any sound.

The "shark lizard" did not move, as if it was picking the first target to attack. At the same moment, Zhou Qing in the crowd suddenly shivered all over his body. His right index finger rests on his temple, a gesture that suggests to him his body's ability to sense danger.

In his dark perception world, in the environment that was originally full of hazy sense of danger, an extremely dangerous individual suddenly appeared, if the dire wolf was imagined to be turned into a cluster of gray-white flames in his perception world, then the current dangerous individual is a cloud of black-purple turbid water, and the moment it appeared, it erupted a chilling chill.

"Overhead!" The moment the results of Zhou Qing's perceptual ability were fed back to the brain for processing, he shouted out loudly.

When it was too late, the shark lizard's strong, powerful quadrupeds erupted at an instantaneous speed of 120 kilometers per hour in a bent state, so fast that its body that merged with the darkness was exposed. In the process of rapid landing, it opened its shark-like bloody mouth and aimed at Zhou Qing's head, like a captive with strength.

The moment Wu Qi turned his head, he only saw a black-purple afterimage, and at a distance that he couldn't help with his long knife, he watched as the shark lizard's terrifying tooth cavity and Zhou Qing's human head were about to merge into one!

Laugh at! The hot blood rushed out from under the rapidly sliced flesh, the incision was small, and the impact was so strong that the blood turned into sharp blood arrows, scattering out 5 meters away.

Wang Sheng and the other mercenaries of the Black Gun also turned their eyes. Behind the face armor, the mercenaries' eyes showed a shocked color, but the quality of their professionalism prompted them to immediately raise their arms and aim the muzzle of the black hole at the shark lizard that had landed on the person.

Zhou Qing did not die, but sat down on the ground on the side with a frightened face. At the last moment, it was An Yi who crashed into him and saved his life by taking his place. The two arms that were as thick as a log pillar crossed to block replaced Zhou Qing's head and was bitten by a shark lizard. The teeth on both sides of the shark's mouth were three minutes longer and cut deep into the comfortable flesh, and the remaining teeth were only two or three centimeters away from biting in.

Because it was a cross-blocking stance, An Yi just grasped the two long tusks of the shark lizard with his hands at the critical moment, making it difficult for the shark lizard to gnaw it completely. The tips of the fangs tore deeply and widened his flesh, and the sharp pain made An Yi's scalp burn instantly, his eyes bloodshot, and his vision blurred. At the same time, the sharp claws of the shark lizard's two forefeet were frantically tearing at the muscles near An Yiyi's shoulder, almost tearing the whole piece of flesh apart.

Bang! A rough roar suddenly inserted into the bloody standoff scene. The steel bullets from the shotgun were all shot into the shark lizard's head at close range. The hail held by Dayong's hand. The muzzle of the shotgun, the smoke of gunfire exploded like fireworks. His eyes were terrified, and his entire face and arms were wet with sweat.

The shark lizard let out a sharp chirp, and its whole body trembled as fine black blood overflowed from the dense holes in its folded skin, and its bite force was greatly reduced, and An Yi had a chance to fight back. The strengthened force erupted and groaned over the root muscles. As he groaned, he pulled the shark lizard's tusks out of his lower arm and pushed them away.

The moment the shark lizard's body fell to the ground, its slender tail and four legs began to instinctively react and move, trying to escape. However, the people of the black gun had been waiting for a long time, and the dense metal bullet stream instantly submerged the body of the shark lizard, and after being shot more than 30 times in two seconds, it struggled to fly more than 6 meters away, and then fell heavily to the ground.

"Fuck it!" An Yi exhaled a mixture of sweat and blood, and his strong body sat directly on the ground. The two thick forearms on each of the two blood holes flowed out like springs, which showed how deep the shark lizard's bite was.

Some of the mercenaries of the black gun leaned over, and Wang Sheng walked near the corpse of the shark lizard and solemnly observed the appearance of the shark lizard. After a few seconds, he turned to look at Comfort, surrounded by others.

Wang Sheng, who came from a base with sufficient living resources and security, had always thought that the barren safe zone was no different from the starving wilderness, and the people of the wilderness were those who had abandoned their humanity in order to survive and could betray their companions mercilessly. But at the moment when his actions were all instinctive, An Yi would rather be injured than protect Zhou Qing.

Comfort, this man lives more like a person than most of the guys at the bottom.

Wang Sheng straightened up, feeling a little more respect for the leader of this barren safe zone. The members of the mercenary team also took gauze and anti-inflammatory drugs in their backpacks, and wanted to use these medicines, which were very rare in the safe zone, on An Yi's body. Wang Sheng took two steps closer and said in an indifferent and emotionless tone:

"Deputy Liu, take out the hemostatic spray from the marching bag."

Deputy Liu was stunned for a second, and then quickly understood what Wang Sheng meant. He took the hemostatic spray from the car. It is a tube of sprays with a clear appearance of civilized times, with a fine text description written in black on a white background, and the red logo of the pharmaceutical company. In the G011 base, the price of this tube of spray can be sold for 400 yuan, and the treatment effect is self-evident.

The mercenary team and others were a little stunned by An Yi, as a mercenary, he naturally stayed in the base and knew the value of hemostatic spray. He watched Deputy Liu spray a large amount of medicine mist in the hemostatic spray on his bloody wound, and the deep wound was quickly cooled and coagulated and sealed by the medicine mist, and the flesh and blood turned out gradually became a little itchy.

"The likelihood of tetanus will be greatly reduced, and as for the plague virus, it can only depend on your luck." Deputy Liu took the spray and explained to An Yi. Obviously, Anyi's act of saving people just now also made Deputy Liu's evaluation of him improve.

An Yi was a little caught off guard by the kindness of the Black Gun Mercenary Group, and his eyes showed a deep sense of gratitude, not as against his will as before, but genuinely moved: "Oh, oh! Thank you, Brother Liu, and thank you, Brother Wang. ”

"Alright, you guys, put this plague in a specimen box." Wang Sheng pointed to a few people in the black gun and waved his hand. As he turned around, he suddenly found Wu Qi squatting at his feet.

"When did this guy come over? There was no sound at all. The corners of Wang Sheng's mouth twitched, and then Wu Qi stood up and looked at Wang Sheng, his dark eyes were smart and energetic.

"Look at the top, this plague seed is coming out of the wall above, and my hearing doesn't hear a sound. Its folded skin is also entirely in the service of silent drilling, and I'm afraid it's a scout-like creature in the group. ”

Wang Sheng followed Wu Qi's gesture and looked up, but he didn't have enhanced his vision and didn't wear night vision goggles, so he couldn't see clearly. You can only roughly see a small vertical cavern suddenly appearing in the otherwise smooth concrete wall. The cave appeared in this location, and it was abruptly scary.

"You're right, most of them are plague species that can drill into the earth. And its body mutated like this..... The extent of the virus is surprising. ”

After Wang Sheng replied to Wu Qi's words, he suddenly remembered why he replied to Wu Qi's words so seriously. He obviously didn't do anything, or only analyzed a little bit of what he agreed with. And he had collided with himself before, and was almost killed by his own subordinates.

Wang Sheng was silently annoyed by his strange reaction, and he said, "Boy, listen to your tone, do you have an enhanced ability in hearing?" ”

"There is a level of listening reinforcement." Wu Qi replied without rebuttal. He hadn't actually been exposed to any genetic enhancement potions at all, and had only learned about the background from Ruoying. His keen hearing was completely exercised, and in the case of a vague level of ability grading, Wu Qi chose to say in a way that Wang Sheng could accept.

Wang Sheng nodded lightly, it seems that this kid is not useless.

"Then again, if a plague species can drill into the earth, so can an individual of the same type. Moving forward so far, I have always had the feeling that the entire tunnel is exposed to a damp and aerated layer of soil, and now it seems that perhaps this high-speed rail tunnel has long been a nest for the plague to be completely operated. ”

Wu Qi slowly said his deep feelings. The purpose of saying this is to make Wang Sheng not limit himself to the surface that has already been discovered, but to raise a higher vigilance. Because Wang Sheng generously helped An Yi, Wu Qi's negative feelings towards him disappeared a lot, and he even had a good impression.

But these words made Wang Sheng shiver, and a cold feeling piercing the bone marrow rushed from the soles of his feet to the top of his head.
