In the corridor leading to the core area of the biochemical laboratory base, two armed NPC guards of the combat team will suddenly appear at regular intervals to intercept them.

The exchange of firearms and weapons was extremely fierce in the slightly narrow corridors, the lines of fire shuttling back and forth, and the high-explosive grenades that tracked over the corridors, all of which had to make the people in the war tense their nerves and go all out, because they all knew that if they were not careful, they would bury their lives here.

Beware of grenades.

After Chen Ye threw a high-explosive grenade into the bunker temporarily constructed by the armed guards, he immediately felt out a high-grade smoke bomb, and then quickly pulled the fuse and threw it, and then the cat's waist was in front of the bunker that had lost the defense of the armed guards, and then made an 'OK' gesture towards Jiangshan.

Bang, poof.

The loud explosion of the high-explosive grenade and the flames that rose in an instant immediately caused the armed guards behind the bunker to stop shooting and bury their heads behind the bunker, and when the aftermath of the high-explosive grenade was over, the armed guards immediately raised their heads and prepared to shoot.

It's just that a cloud of white smoke has already filled the area in front of the armed guards, and everything in the enemy area is naturally covered by this smoke.

In the face of blind spots caused by smoke grenades, blind shooting will not achieve breakthrough attack results, but will only waste bullets.

Therefore, at this moment, the armed guards all chose to stop firing and wait for the smoke to clear.

However, at this moment, that is, after the corridor battlefield fell into a brief silence for a second, several wind-breaking sounds suddenly came from the white smoke.

Immediately, in the eyes of a certain armed guard, Chen Ye's figure holding a backstabbing dagger and running at full speed suddenly appeared in the white smoke.

Bang, bang, bang.

The armed guards, who had long expected such a surprise scene, pulled the trigger on the raider without saying anything, but the moment the armed guard pulled the trigger, they suddenly realized that the raider was just a decoy, and the real killer was a few other figures that jumped quickly.

"Well, it's a juvenile."

In the exclamation of the armed guards, the killing hands of Jiang Shan and Soul Desire quickly narrowed and enlarged in the pupils of the armed guards.

Poof, poof.

The sound of flesh and blood being pierced directly by both hands sounded in unison, Chen Ye watched the young body team led by Jiang Shan fight to the armed guards behind the bunker, smiled proudly, and then took out the HP recovery injection from the medical box and injected it, although the iron-blooded suit has a rare armor specialization +3 additional attribute, which can directly reduce the red damage output of the firepower weapon by 300 points, but under the fire of seven or eight armed guards, even if it is a single-digit red injury output, there will be hundreds of red damage output within five seconds.

Chen Ye is not the boss, so he does not have the generous treatment of the boss.

"Holy shit, there are two defenders on the team, and they actually call snipers to act as bait, which is definitely non-racially." Chen Ye grumbled while injecting the HP recovery injection.

Soon, Zhao Yan and the others appeared behind Chen Ye one after another, and Feng Xingchen couldn't suppress the admiration in his heart, walked directly to Chen Ye's right side, patted him on the shoulder and said, "Brother Shu, I think you have more potential as a defender than me." ”

"Don't call me brother." Chen Ye replied immediately.

"There are really talents in the country, and there are ** people in the wind, and we still look at the present." Dr. Han was really satisfied with the combat strength shown by Chen Ye and the others along the way, and every time he successfully broke through a level, he would express his feelings behind everyone, and then he would go on to say the content of the next level: "The following is the last level to the core area of the laboratory, and you will only be greeted by two light mecha soldiers." ”

"It shouldn't be very difficult." Chen Ye pulled out the HP recovery injection and threw it to the ground.

"Since there are only two light mechs, let's move forward in a standard combat formation, and remember to minimize the damage to the buildings of the laboratory base while ensuring that you have your own life." Zhao Yan took out the RPG bazooka at this time, carried it on his shoulder, and admonished.

"Yanzi, how do I feel that you have started to maintain these equipment before this base is occupied." Chen Ye couldn't help but tease, which immediately caused a burst of laughter, and the faint uneasiness hidden in everyone's hearts decreased with the harmony of the atmosphere, after all, Dr. Han's description of Heigen, the lord of the laboratory base, was a bit perverted, so everyone's hearts could not help but be suppressed by an unknown powerful lord.

"By the way, I forgot to remind you that light mechs are very lethal to young people, so you can just stay by my side and protect me."

I don't know if it's out of concern for my own safety, or if the light mecha soldiers really have the lethality of young people, Dr. Han looked at Jiang Shan and said very seriously.

For a doctor of biochemistry who has been engaged in the career of graduate chemical viruses for more than 30 years, the right to speak in his mouth always has the power to be deeply convinced unconsciously, so the entire young body team of Jiangshan was left by Dr. Han's side, and Chen Ye took out a Barrett M95 sniper rifle and followed behind Zhao Yan, walking towards the final level.

After passing through a metal door, an extremely wide hall immediately appeared in front of Chen Ye's eyes, and there were neatly arranged shelves in the hall, on which various experimental instruments and animal and plant experimental subjects were placed, and even on a certain shelf, Chen Ye was extremely frightened to find a human corpse, although the hands and feet of the human corpse were fixed, but just the body that was destroyed into a shapeless shape would give people an indescribable visual impact.

After seeing this human test subject, the first thing Chen Ye did was to swallow a mouthful of saliva into his throat, then turned his head, stared at Dr. Han and asked, "You don't usually do this biochemical experiment, do you?" ”

Dr. Han looked at the human corpse with disdain: "That's what a low-level apprentice does, I think a doctor of my level already disdains this kind of pediatric thing."

"Then what you're studying now." Dr. Han's words with such an expression immediately aroused the curiosity in Chen Ye's heart, so after Dr. Han's words fell, he couldn't help but ask.

"My current level should be able to study creatures such as high-level alien beasts, but the only alien beasts in the biochemical laboratory are the bottom of the alien color, if it is an alien queen, it is slightly better, and the rest is basically a dish."

The biochemical weapon alien series that made players extremely panicked was actually just a dish in Dr. Han's mouth, if this was transmitted to the A-level survivor base, I don't know what kind of topic craze would be set off among the player group, although Chen Ye was also deeply shocked by Dr. Han's words at the moment, but he extracted a key message from this sentence that made him extremely shocked.

Alien beasts exist on the map around the AA-level survivor base, but the alien is only the bottom of the role, but the alien is a lingering nightmare in the player's heart, and this is enough to show what a terrifying existence the alien beast on the map around the AA-level survivor base will be.
