Chapter Index

    But unlike ordinary guinea pigs, this guinea pig was fat and large, and visually its size was almost like a small piglet, with black and shiny fur.

    For Feng Yi and the others, no matter what rushed out of this thick fog, there was only one way to deal with it: shoot!

    “Da da da da…” Gunshots rang out instantly, and the muzzle flash illuminated the walls on both sides of the tunnel ahead, which was obscured by the fog. All that could be seen on the walls were irregular bloodstains that had already congealed, as well as scratches of varying sizes and depths. On the ground were some pieces of meat and scraps of meat that were unidentifiable, and even more patches of blood that had not yet dried.

    It was obvious that before the group arrived, there had already been countless cruel fights here.

    The gunshots rang out briefly, and then the group stopped firing. The guinea pig that had rushed over had already been riddled with holes, and brownish blood was gurgling out of the bullet holes. It fell to the ground and was still kicking its legs Keep going.

    “D-dead?” Shao Mingyao raised his gun and retracted it, asking uncertainly.

    “We fired twenty or thirty bullets. Even if it were a nine-tailed fox with nine lives, it wouldn’t be enough to survive,” Deng Yao replied, taking over Shao Mingyao’s words.

    “That’s right. There’s no tangible enemy that our hot weapons can’t handle.” Wu Shengwei’s greatest fear in life was things that couldn’t be seen or touched. Seeing that what had rushed over was just a mutated guinea pig, he put down the big stone in his heart, breathed a sigh of relief, and laughed along with their conversation.

    However, Feng Yi, who was in the lead, remained silent. It wasn’t until the three men’s voices faded away that he raised his hand to signal them to be quiet.

    At this moment, the entire fourth-floor underground laboratory returned to an atmosphere of silence. After it quieted down, the group slowly heard some trivial and chaotic noises through their helmets, as if they were coming from a very distant place. Then the sounds became louder and louder…

    “Not good!! A large number of mutated creatures are rushing over!! Follow me! This way! Quick!!” After hearing the sound getting louder and louder, Feng Yi’s face stiffened suddenly and he shouted at the other three. While shouting, he took the lead and ran into a side road towards the nearest laboratory.

    The others only paused for a moment before realizing something and quickly followed behind Feng Yi.

    If the number of creatures attracted by the gunshots just now was small, it would not have been possible for such a loud noise to have traveled from so far away. But if there was a group of swift creatures like the mutated guinea pig just now, the four men would have no way to deal with them in the tunnel. After all, the rifles in their hands were not unlimited weapons that didn’t need to be reloaded. In other words, as long as their firepower was not enough to cover the entire width of the tunnel due to the pause in between, mutated creatures would break through their fire line blockade and attack them. At that time, it would be an irresistible and devastating disaster for the four of them.

    Therefore, Feng Yi made a decision in a flash of thought – he had to avoid this wave of mutated creatures first. Although the time left for them to move freely here was not much, he could not let the three men risk going to the security door between the fourth and fifth floors to swipe their ID cards with him. After all, the fourth floor was the only way back for the group. If the appearance of those mutated creatures prevented them from returning the way they came, then they would only be able to die here with regret. Therefore, at this time, neither choosing to fight those creatures head-on nor escaping to the fifth floor underground was the most appropriate decision, and they could only find a laboratory nearby to take refuge first.

    The fourth-floor ID card in Feng Yi’s hand was a universal ID card for the entire fourth floor, so it could open any laboratory here. Fortunately, although most of the electrical facilities on the fourth floor had lost power support, the access control system was still usable, so the four men successfully entered a nearby laboratory.

    Just as the four men locked the door of the laboratory, they saw a dark mass of shadows covering the bulletproof window on the side of the laboratory.

    Even though the group was already in the laboratory at this time, and they were seeing this scene through night vision goggles, the shock in their hearts was still difficult to calm down as they watched such a large group of mutated creatures swarming up the transparent window.

    Fortunately, Feng Yi’s decision was made in time. Otherwise, if they had faced these mutated creatures head-on at this moment, they would definitely have ended up dying without a burial place. The group had no doubt about this.

    After all, the creature lying on top of the glass was a dog-headed bat with a wingspan of more than one meter, and below it was an ape that was half a person tall, baring its fangs and scratching the outside of the glass, making ear-piercing squeaks.

    Behind them were mutated goats, mutated pigs, and even mutated rabbits the size of medium-sized domestic dogs. The most important thing was that there was not just one of each animal…

    Of course, the animals used for experiments in the laboratory were not limited to these types. More of them may have already been eaten by these more powerful creatures in the previous battles…
