Su Chen ran all the way, and when he came to the mutant black cat, Blizzard had already covered up its bloodstains, Su Chen carried the knife, half-squatted, and poked the mutant black cat's body with the tip of the knife.

The mutant black cat took a hard shot, the 12mm sniper bullet is not a joke, one shot, most of the mutant black cat's body was shattered, only the head and the small half of the body remained, and even the forelimbs were torn apart.

The mutant black cat is worthy of being a second-level mutant creature, and its vitality is more tenacious than that of a first-level mutant creature, although death is inevitable, but it still has a breath now, and it is the best time for Su Chen to mend the knife.

Su Chen didn't think much about it, and after making sure that it was not dead, the Nepalese saber went down and inserted it directly into its head, the blade was submerged, and the head of the mutant black cat burst like a watermelon, and all kinds of disgusting liquid flowed to the ground.

Behind Su Chen, the black panther frowned slightly, he didn't expect Su Chen to have this kind of habit, and he didn't know what to say for a while.

After killing the mutant black cat, Su Chen didn't stand up in a hurry, he knew that the system prompt of the zombie illustrated book would appear soon.

Sure enough.

Fortunately, Su Chen arrived in time, if he followed the team forward, the half-dead state of the mutant black cat would never be able to support his arrival alive.

This person picked up the head just right, Su Chen's action was not in vain, and the bright three stars in front of him were enough to make up for the previous few fatal battles.

"I don't like cats very much..."Su Chen turned around and saw that the black panther had a strange face, so he had to mess around.

The black panther didn't doubt it, he nodded slightly, and said, "You hater cat has to change your temperament, it's too dangerous to rush out like this." ”

"No problem, definitely pay attention next time." Su Chen nodded in response.

"Dead?" Huang Long, who came quickly, looked at Su Chen and asked.

"Dead." Su Chen glanced back at the mutated black cat with both halves of his head, he wasn't sure what Huang Long meant by asking.

"It's good to be dead." Huang Long never looked at the corpse of the mutated black cat, and for him, the glory of a sniper could not afford him to make a mistake.

The hiccup passed quickly, and the goshawk team arrived quickly with the team, and the goshawk team continued to move forward.

At the gate of Building B's experimental building, Su Chen and the others lined up, shook their bodies, and cleared the snow on their clothes and pants.

It's half past one in the afternoon, and in winter, the sky should be bright, but under the snowstorm, the whole world is full of darkness, and it is only a line away from pitch darkness.

The lights in the experimental building were brightly on, and everyone could see the expressions of their comrades through the light, except for Su Chen, the rest of the members of the goshawk team had the same expressions, they were not nervous, not excited, and did not have any negative emotions, Su Chen didn't know how they did it.

"Rest in place for twenty minutes." After several actions, the team members are physically and mentally tired, and now they finally have a place to adjust their state, and the goshawk will not blindly speed up the progress of the task.

Su Chen took off his combat uniform, threw it aside, leaned against the bulletproof glass door, crossed his hands on his waist, closed his eyes, and said slowly: "Remember to call me." ”

No one responded, and everyone took advantage of this time to rest.

The goshawk was also resting, his way of resting was leaning against the marble pillar beside him, he didn't close his eyes, and although the exertion made his alertness low, the average creature still couldn't escape his sight and perception.

As the captain, Goshawk naturally bears the most tiring and bitter work, and the captain of the special squad is not something that all special forces can do.

Twenty minutes is simply a moment for Su Chen in his sleep, he was in a daze, heard a soft shout, and when he opened his eyes, he saw that this group of team members was ready to go, and Su Chen was still in a state of half-dreaming and half-awake.

"I'm sorry." Su Chen rubbed his eyes, picked up the combat uniform on the ground and hurriedly put it on his body, a cold wind blew, he shivered, and he was much more sober.

"It's okay, we'll wait for you." The goshawk's tone was not hurried or slow, and he didn't care.

Su Chen put on his military backpack, rubbed the back of his head with some embarrassment, and said, "Next time I set an alarm clock, it will definitely not be outdated." ”

"You haven't been trained, so it's understandable that we're not missing that minute." Goshawk smiled.

"It's much better than I was." The black panther stretched out his fist and gently hammered it on Su Chen's right chest, and said with a smile.

"Okay, everyone adjusts to the state, the next action may be more difficult, and there will be no rest time in the middle, get ready, let's go." Goshawk returned to its previous coldness and said solemnly.

Su Chen, who woke up from his sleep, was rarely able to wake up in a short time, but this time he was surprisingly awake, he opened his eyes wide, watching the goshawk enter the password and fingerprints, and as the bulletproof glass door moved to the left and right, the goshawk at the front of the team took the lead in stepping into the building.

The lights in the building are very bright, but not dazzling, a few steps away from Su Chen on the left side is the front desk of Building B Experimental Building, there should have been a few beautiful young ladies showing sweet smiles, but now only a few dried blood stains remained.

"Everybody be on your guard." When the goshawk saw the bloodstains, he immediately estimated several dangers in his heart.

It seems that the experimental building, known as the Iron Beast, cannot stop the invasion of mutated creatures.

The entire laboratory building is very quiet, even if the goshawk team is pressing forward, on the smooth tiles, it can still cause a sound.

Building B is very large, and there are partitions inside, and Suchen is now in the center of District 1, that is, the main hall of Building B Experimental Building.

There are a total of 12 districts inside the B laboratory building, and Su Chen is going to 11 districts, the higher the number, the higher the floor, and the status of the staff in the B building is also high.

The elevator in Building B was no longer functioning, and the Goshawk team was forced to enter through the emergency exit, and Dr. Carlin and Dr. Charlene's private laboratories were not on the same floor, Dr. Carlin's laboratory was on the 21st floor, in the east corner, while Dr. Charlene's laboratory was on the 22nd floor, in the west corner, and the team obviously had to make two trips.

Building B has 23 floors, excluding the underground garage.

The emergency exit is located at the east corner of the laboratory building, which means that from the emergency exit, you can see Dr. Carlin's private laboratory within a few steps.

However, this is only the simplest of the hypothetical rescues, in fact, there is no more than 10% chance that Dr. Carlin is still in his lab, and if he is not found in Dr. Carlin's lab, and Dr. Carlin's death is uncertain, the Goshawk team will need to turn the entire B laboratory building into the sky.

The team trotted all the way to the 21st floor, except for Su Chen's physical strength obviously couldn't keep up, the rest of the team members were in good shape, Su Chen didn't know how they usually trained, but what was certain was that the endurance of this group of special forces was absolutely unimaginable to ordinary people.

The goshawk took good care of Su Chen very much, and under normal times, the team had already pushed open the gate and started to act, this time it was exceptional to rest in place for a minute, so that Su Chen could slow down.

Maybe it was because of the reason for becoming a second-level immunizer, Su Chen's physical recovery speed was much faster than that of ordinary people, he took a few breaths, and said lightly: "No need." ”

Su Chen's current state will have an impact on his close combat, but the Goshawk Squad is fully armed and does not need to fight in close combat.

The goshawk didn't say much, pushed open the door, and the black panther and Su Chen behind him rushed out at the same time.

The corridor of the laboratory building is very narrow, less than two meters wide, Su Chen's body just flashed out, and a few black shadows appeared in the corners of his eyes, he didn't think about it, mentioning m4A1 is a round of point shooting.

On the other side, the black panther was also attacked by zombies, and his reaction was no slower than Su Chen's, but there were only six black shadows in front of him, and under the strafing of AK, they fell in a pool of blood.

The team members came to the corridor one after another, the narrow corridor was very unsuitable for close combat, the previous zombies appeared too suddenly, and there were many of them, Su Chen and the black panther had to shoot.

AK's gunfire doesn't need to be described, a few shots can "activate" all the zombies on several floors, but fortunately, the goshawk team doesn't care about revealing the location, for them, the battle is a matter of time.

The goshawk closed the door and ran down the hallway.

Although the corridors here are narrow, they are very numerous, and they are all transparent, so you can see at a glance whether there are zombies or not.

The goshawk didn't run for a moment before he stopped, his eyes narrowing slightly, and he looked at the laboratory in front of him.

This is Dr. Carlin's private laboratory, which occupies a very large area, and as the top scientific researcher in China and even in the world, he is very well paid.

Su Chen quickly followed the pace of the goshawk and looked over with his gaze.

The main entrance of Dr. Carlin's private laboratory, and the only door, the door was not closed, the blood stained the glass, and ten centimeters inside the door, a middle-aged man in a white coat died tragically on the ground, his body was bitten by zombies, and the white coat with dozens of cuts barely covered the bloody body.

Goshawk's face was a little ugly, he opened the glass door, the huge laboratory could not be seen at a glance, in the line of sight, on the ground, on the chair, and even on the table, you can see the corpses of the researchers, maybe the zombies are tired of eating, and want to change places, this laboratory only leaves a room full of corpses.

The corners of the goshawk's eyes suddenly lit up, and then his expression was as ugly as constipation, he saw that Dr. Carlin was no longer complete, he exhaled, took out a miniature camera, and recorded everything around him, and ten seconds later, the goshawk said coldly: "The second target is dead." ”

As for the goshawk, he would rather go through the entire laboratory building than see the target die.

However, Su Chen is different, if there is no target person in the laboratory, he prefers that the target person will die aside, rather than taking a great risk and rummaging through the entire laboratory building.

Goshawk was in a very bad mood, so he sped up and hurried to the 22nd floor.

However, no matter how fast he was, there would only be a minute difference in the middle at most, Su Chen didn't think that he could change anything, but for Goshawk and the other team members, they needed this minute very much.

In the corridor on the 22nd floor, several zombies were walking around carelessly, and the previous AK gunfire attracted their attention, but after no target was found, they calmed down again.

Su Chen and Black Panther easily harvested the zombies in the corridor, and before all his teammates entered the corridor, Goshawk ran quickly towards Charlene's laboratory, he didn't want to see Dr. Charlene die tragically in the laboratory.

If this is the case, for him, this operation is really a failure to the extreme, he has participated in 11 rescue missions, a total of 81 large and small missions, and there has never been a mistake, this time, he does not allow mistakes, nor does he allow the Goshawk team to have a case of failure.

Except for Su Chen, all the team members can understand the current mood of the goshawk, they are soldiers, no matter what the reason, even if the target of the rescue dies before they arrive, it is their responsibility.

In fact, it is not their responsibility for the target to die before they arrive, and even if the mission fails, it will not be counted on their heads, but all the soldiers involved in the rescue mission do not think so, in their eyes, it is a failed rescue.
