After killing the two red biochemical ghosts, everyone retreated to the small space behind the big iron gate, perhaps because these biochemical ghosts had little intelligence, the iron gates on both sides of the small space were not attacked for the time being, but Feng Zhan understood that it was only a matter of time.

"Quick, here's a secondary weapon."

Feng Zhan opened these yellow boxes, Feng Zhan didn't expect that there were bullets matching the caliber of these pistols in the boxes, and then Feng Zhan handed the pistols to everyone in turn.

With everyone's firepower, with the fall of the last biochemical ghost in this wave of attacks, everyone was able to breathe temporarily, although there was no ghost army to attack for the time being, but everyone understood that this was only temporary, and no one knew when the next wave would come back, and the hall in front of them was full of blood, and dark red blood could be seen everywhere.

"Whew! I'm so tired! If I make it out of here alive, I'm definitely going to go on a vacation to relax, hey! Feng, do you want to be together? Feng. "Lucas seems to have been born to liven up the atmosphere, and that's when he can say such heartless things.

"Ahh

As if Lucas's voice was heard, a low roar rang out again.

"Ahh Damn it, Lucas, can you keep your mouth shut? It was the youngest girl in the crowd who spoke.

"Uh, hehe!" Lucas scratched his head in embarrassment, even though he didn't have any hair.

"Boom!"

With the sound of the door opening, in the small space, the big iron door behind everyone was opened.

"Bring some more ammunition, we're going to get out of here." It was Feng Zhan who spoke.

Everyone quickly grabbed some magazines from the green ammunition box that had been moved, and ran towards the iron gate, which was a downward slope, and then the voice of the headquarters came over the radio: "We opened the entrance to the underground passage, but, there is bad news, a defense system in the building has been activated, and the poisonous gas will spread immediately, and move quickly towards the underground passage." Then there was silence again.

Everyone went down the slope and turned left, someone looked at the elevators along the way, and Feng Zhan said: "It's useless, those elevators don't have switches, and they can't be opened from below." ”

Hearing this, the man was slightly disappointed, and then continued to move forward with everyone.

After walking a long way, the group turned two more turns to the left, and then they came into view of a door in the distance, there was a green light on the door, the light made the door look green, and the low roar behind them and the green light seemed to look a little like some horror movie.

"Ahh

"Ahh The man let out a scream, and his arm was bitten.

"Pete!" Hank shouted his name, and then raised his hand and shot the junior ghost in the head, he was not afraid of accidentally hurting his own people, that was his confidence in his marksmanship as a veteran.

Then Feng Zhan realized a serious problem, this is not a game after all, so after being bitten, will he be infected? Immediately, he patted his head and remembered that he had a system, so he quickly tested it with the system, and the data was as follows.

"Name: Rochelle Pitt"

"Faction: Defenders"

"Age: 40"

"Rank: Private of the Third Class"

"Physical Strength: 35%"

“HP：100”

"Combat Strength: 135"

"Enhancement: None"

"Physical Status: Currently infected by a primary biochemical virus, will mutate in twenty minutes."

"Mercenary Level Assessment: N Level"

"Instructions: Don't give him your back, it's best to free him before he mutates."

Seeing this, Feng Zhan's face became more and more ugly, so he asked the system, "How can I put an end to infection?" ”

"Dear host, anyone with a physical strength of more than 40% can be immune to primary biochemical viruses, and when the strength reaches 100%, it can be immune to second-order biochemical viruses, and so on." Systematic mechanization of the explanation.

Then Pete stood up, and after struggling inwardly for a while, a flash of determination flashed in his eyes, and he immediately said, "Oh! Comrades-in-arms, I feel very bad now, I think I may be infected, follow you again, I'm afraid I will hurt you, I'll go here, you leave as soon as possible, I'm here after I break off, I hope to do something for you to get out of here alive at the last moment of my life. ”

After that, he took out a photo and handed it to Feng Zhan, "This is my daughter, I can't go back this time, it's her birthday in a few days, I hope you can help me go and see her after you go out from here, she is in the Celestial Empire group of the Spirit Fox Organization among our defenders, and there is her contact information on the photo, hehe, in fact, I don't mind you chasing her, because I think you are very good, you can keep a clear head at all times, I hope you will be the same in the future, and please tell her that I owe her mother and daughter." ”

Then he turned and ran back, pulled out the submachine gun on his back, and picked it up, then disappeared around the corner, and then only the sound of a loud gun could be heard.

"Come on! Ha ha! Come on, grandchildren, grandpa is here. Pete's somewhat frantic voice came from around the corner.

Then everyone stood in place and saluted in unison to the corner where Pete had disappeared, a man worthy of their respect.

Then the crowd stopped procrastinating and continued to move in the direction of the green door.

Because of the fact that one person has just been reduced, everyone's morale is a little low, but the deceased is gone, and the living must live with his hope to live up to him.

"Wow! The underground sewers are very complicated, but we hacked into the system there, and just saw through the camera there that there are directional signs on the wall, don't lose your bearings, we'll look for the next channel, and the call is over. After saying that, the headquarters fell silent again.

"There's the primary weapon over there, it's time for a wave of gear." Feng Zhan pointed to a pile of slightly long blue boxes in the corner of the wall.

Hank saw a stack of green ammo boxes, and after a few inspections, he saw bullets that matched his M4 caliber.

Feng Zhan found an M4 in the box, and the others all got the M4 or G36X assault rifle.

"Finally there is a guy who can use it, but why are you always better than me?" Lucas pursed his lips and said helplessly.

Everyone skillfully loaded and loaded, and then Feng Zhan found a few brown boxes, he knew what they were, and then he opened the boxes and distributed the biochemical grenades that had not had time to be patterned one by one. And instructed: "This may be our lifesaver." ”

"Ahh

Feng Zhan's eyes flickered, he knew that Pete was already dead, although he had only known everyone for a few hours, but the friendship of life and death was the most iron, and just now Pete resolutely chose the queen for them to live, this comradeship is enough to make people moved.

Thinking of this, Feng Zhan raised the M4 in his hand and poured out bullets of hatred, and everyone opened fire on the swift biochemical ghosts that followed.

"Jingle ......" It was the sound of bullet casings falling to the ground, and the powerful fire of the assault rifles caused the swift ghosts to fall one by one before they could get close, but it was nothing, everyone understood that the huge number of primary biochemical ghosts behind them and the unknown number of little red were the most troublesome.

Thinking that in the game, there seemed to be something strange on both sides of this hall, Feng Zhan couldn't help frowning.

"Boom! Boom! Boom! ”

It was the sound of the elevator, and there were three red ghosts standing in the three elevators on the right side of the hall, and when he saw this scene, Feng Zhan's pupils shrank sharply, and then he shouted to everyone suddenly: "Go to the corridor quickly, these things are too thick, and they must use grenades." ”

With that, he took out the gray-white biochemical grenade and ran towards the corridor, and the rest of the people completed Feng Zhan's instructions in two seconds.

“Fire in the hole！” Feng Zhan shouted, and then the grenade crossed a beautiful arc in the air, and then fell, jumped on the ground twice and rolled to the feet of the three red ghosts, but I didn't expect this grenade to make the red ghosts run over slightly, they all looked at the grenade on the ground, as if they didn't understand that this was a thing, and then there was no more.

"Boom!"

A deafening loud noise, as well as a slight shaking of the ground, made everyone in the corridor understand the power of this grenade, and several red ghosts were blown up in all directions.

"Ahh

It was still a low roar, everyone understood, trouble was coming, and what caught eye was a dense group of primary ghosts, but fortunately, everyone's equipment was updated to assault rifles, and the powerful firepower of assault rifles was not covered, and everyone's concentrated fire made these junior ghosts unable to advance for half a minute, but the swift ghosts that rushed out from time to time made everyone have to be distracted and killed, and in the long run, the junior ghosts were approaching everyone at an inconspicuous speed.

"Oh! I swear, you won't want to be kissed twice by them. ”

Lucas always seems to be able to ease some of the tension.

Looking at the approaching army of junior ghosts, Feng Zhan was in a very bad mood.

"Wow!" A radio murmur made Feng Zhan's brow stretch slightly, he knew what it meant.

"Wow! We searched all the closed doors and opened the door to the next area! Avoid the poison gas and move quickly! We'll go open the next door and we're done! ”

"Boom!"

The placket on the left side of the hall was opened, and the time was tight enough for everyone to report to headquarters.

Everyone fought and retreated, and after walking for a distance, they came to a hall again, where there was also a pile of green chests, everyone knew what they were, and there was also a pile of brown chests on the ground, which were biochemical grenades.

"Oh! Damn it, I think I know how to stop the damn bunch behind me! ”

This time it wasn't Lucas who spoke, and everyone saw Hank show a cheap smile, and then suddenly heard a voice: "Fire in the hole!" ”

"Jump!" There was another loud bang, and the hallway from the previous hall was filled with broken corpses and severed arms.

The hallway suddenly emptied, but it was soon filled with other junior ghosts.

I don't know what material the building is made of, but after experiencing the powerful destructive power of the biochemical grenade, there are only a few more potholes on the ground.

"Boom!"

This voice made Feng Zhan's heart sink again, he understood what it meant, there was something strange in the elevator here, so he quickly turned the head of the gun and spat out tongues of fire at the several elevators on his left.

A red ghost, two swift ghosts, and a junior ghost quickly fell under Feng Zhan's M4.
