The group walked slowly in the long passage, all of them raised their vigilance to the highest level, but some light bulbs in disrepair flashed like ghost movies, making the already solemn atmosphere even more tense, even if everyone deliberately controlled it, they still couldn't suppress it, and heavy breathing was constantly squeezed out of their chests.

"What the hell is going on, how do you know her cannibalistic ......"

Just as everyone turned into another corridor, Li Tingyu finally couldn't help but drag Chen Guangda, and Chen Guangda sighed in a low voice and said: "Actually, when I was in the mountain village, I found out that the footprints of one of the corpses belonged to Colleen, but at that time I thought it was just a coincidence, so I only paid a little attention in secret!"

"So how the hell are you sure, this kind of thing can't just be based on feelings......

Li Tingyu was obviously a little anxious, but Chen Guangda continued: "I have set up a lot of early warning devices in the stadium lounge, but none of them have been touched until Lao Zhaotou is killed, so the corpses will either pass through the wall or walk in through the gate in a grand manner, but have you seen the other corpses, Colleen is talking alone from beginning to end!"

"Oh my God, could it be that she deliberately killed Lao Zhao Tou just to eat him......

Li Tingyu covered his mouth in horror, but Chen Guangda shook his head and said: "It should have been just an accident for her to kill Lao Zhaotou, remember the broken arm we found in the lounge, that broken arm should have been sent to her by the corpse, but Lao Zhaotou inadvertently found out, which forced Colleen to attack him, in fact, Colleen has been secretly manipulating the corpse!"

"Then Colleen herself knows about this, will she be like you, only in her sleep will be controlled by the gray corpse worm......"

Li Tingyu looked at him with a pale face, and Chen Guangda sighed again: "I tested her reaction, she herself should be very aware of this matter, so I'm afraid she is the same as Zhu Fei, she took the initiative to compromise with the gray corpse worm, the gray corpse worm should have occupied her brain now, and she didn't completely control her just because her strength was not enough!"

"What are you talking about, why don't you leave......"

Colleen suddenly came out from the side, looking at the two of them very curiously, Chen Guangda casually snorted and hugged her and continued to walk forward, but the sad look on Li Tingyu's face could not be concealed, once the gray corpse worm entered Colleen's brain, Colleen would completely become a mutated living corpse.

"Listen to the rain, why are your eyes red, are you hiding something from me......"

Colleen suddenly broke away Chen Guangda's face turned a little pale, Li Tingyu hurriedly wiped the tears that were about to fall, but her face suddenly changed just when she wanted to speak, and she hurriedly shouted that there was a living corpse in front of her, and soon saw two long-tongued monsters rushing over from the front, pounced on them with teeth and claws.

"West Bar~"

The two leading stick ghosts screamed and ran away, but who knew that Shui Zai directly met him, he had already held his stomach for so many good brothers who had died in a row, and he rushed up to fight directly in close quarters without fear of death, but he probably learned a lot from Chen Guangda, and easily killed the two long-tongued monsters between the swings of the short spear.

"What the hell is this......

The two sticks came up in horror, and saw that the two long-tongued monsters were wearing uniform blue uniforms and paper bracelets with personal information written on them, so Chen Guangda frowned and said: "They should be the first batch of infected people, and after being caught, they were used to experiment with corpse poison serum, and the failed serum caused them to become like this!"

"According to that, they should come up from below, and Lao Mei will definitely not put human experiments on the first layer......"

Shui Zai looked at him with some solemnity, Chen Guangda also nodded lightly, it seems that this place is not the same as the Cuiluo Mountain Dam, the experiments in Cuiluo Mountain are all biological weapons, and human experiments should be carried out here after an accident, otherwise the things they encounter will definitely be more terrifying than the long-tongued monster.

"Let's go, let's go to the main control room and have a look......"

Chen Guangda waved his hand lightly and continued to walk forward, these two sticks no longer dared to lead the way, and followed behind Chen Guangda and the others with a cower, but all the long-tongued monsters were probably led away by them, and the group came to the staircase very smoothly, except for some ordinary living corpses, there was no other abnormal place.

"Those things should have been released from below......"

Chen Guangda and Shui Zai glanced at each other, if Lao Mei, who had entered here before, had to leave at least one or two corpses behind, it was estimated that they accidentally ran into something below, so they released the long-tongued monster in one breath, which led to their total annihilation.

"Old Kim, remember to close the door ......"

Chen Guangda instructed the two sticks and walked into the corridor, the two Korean sticks were surnamed Jin, Chen Guangda simply lazily called them Lao Jin and Xiao Jin, and after everyone walked in cautiously, Lao Jin hurriedly closed the closed door, so that there was no need to worry about the long-tongued monster chasing down again.

"Didn't hear anything......"

Li listened to the rain thief's awkward reminder, as long as it was not too surprisingly alive, it would not be able to escape her listening, but Chen Guangda frowned slightly, the staircase did not lead directly to the third floor underground, it seemed that even if they didn't want to go to the second floor, they would have no choice.

Chen Guangda sped up his pace and came to the second basement floor, where the structure was basically the same as above, but there were many more offices and control rooms, but they soon found a bloody elevator, not only a large amount of blood stains were left in front of the elevator, but also a lot of broken clothes and weapons and equipment.

"Do you want to go down or just ......come up?"

Shui Tsai was shocked and walked over, so many blood stains should belong to two people, but unfortunately they had already been eaten up by the living corpses, but Chen Guangda pressed the elevator door with his hand, and there was nothing in the elevator, but there were only buttons on the first and second floors in the elevator, and it was impossible to reach the third underground floor.

"Pay attention, I'm afraid the long-tongued monster came out of this layer......"

Chen Guangda directly threw the corpse claw spear to Li Tingyu, and pulled out the poison hook gun behind his back, although this thing is not very easy to use, the paralyzing toxin that can be carried can deal with some big guys, but they didn't go far before they came to an independent area.

This area is not only blocked by two iron gates, but also hung on the door with a sign that only allows "internal researchers are allowed to enter", everyone immediately walked in cautiously to see, a large number of corpses and blood almost covered the ground, and judging from the weapons left on the ground, it is obvious that it is the US military who entered here before.

"You're waiting here......"

Chen Guangda walked forward alone with a poison hook gun, and soon saw a messy laboratory, the contents of which were turned over by people, a large number of documents and computers were scattered, and a white banner on the wall still read: God . Bless. USN (God Bless the United States Navy)!

"It's ironic......"

Chen Guangda shook his head slightly contemptuously, the blood stains in the laboratory were fresh, indicating that there was no attack on this place before, it is estimated that when the US military came here to collect information, they accidentally touched a switch, and only then released the long-tongued monster imprisoned here, which caused the annihilation of their own people.

Sure enough, when Chen Guangda walked to the front and looked around, more than a dozen cells were all opened, and these electric cell doors would definitely not get out of control by themselves without touching the switch, but this should be just a temporary transformation observation point, looking at the scale of the laboratory, you can know that it is not the main department, and the real main research institute should still be below.

"Let's go!"

Chen Guangda turned around and walked outside, even if the things here were valuable, they couldn't tell the difference, so everyone followed the guidance of the street sign and walked all the way to the general control room, who knew that they were soon blocked by two huge garage doors, and there were two machine cannons hanging upside down on them.

"Look at us......"

Lao Jin did not hesitate to take out the electronic key, swaggered to the front of the library door, who knew that there was no need to plug and pull at all, Lao Jin just raised the key on the door of the library on the green light, two heavy doors immediately to both sides of the rumbling open, until then everyone was shocked to find that the two doors were more than half a meter thick, I am afraid that the *** against the bombardment can not be opened.

"How can there be a door......

Everyone frowned suspiciously, after the library door was opened, it was a very wide tunnel, but there was a roller shutter door inside to block it, but the structure should be an airtight door, it is estimated that it is to prevent toxic gases or radiation from seeping out from inside, and everyone had to walk in.

"Boom~"

The two doors suddenly began to close again, but after they closed suddenly, the rolling shutter door in front of them slowly opened, but a strong smell of blood suddenly wafted out from inside, and everyone hurriedly picked up their weapons and stared at the door nervously, but as a large piece of viscous blood flowed out, they seemed to have opened the gate of Shura's hell.

"I'll ......"

Everyone gasped in unison, and saw more than a dozen corpses of American soldiers lying in front of them, and each one was almost torn to pieces by bullets, and the broken internal organs and corpse parts covered the entire ground, and almost a complete head could not be found.

"How so? Did they have infighting......

Li Tingyu looked ahead with a pale face, these American soldiers were all killed by bullets, it must be the handiwork of human beings, Chen Guangda immediately frowned suspiciously, the front looks like a very ordinary hall, and a few closed rooms don't know what to do, but unless someone sets up a heavy machine gun in front, it is impossible to beat people like this.

"Drop~"

Suddenly, a green laser shot down from the top, and everyone in fright took a big step backwards, but the laser light did not do any harm, but projected a large piece of English letters on the ground in front of them, neatly like a computer keyboard.

"What the hell is this......

Chen Guangda stared inexplicably, who knew that he suddenly heard two more booms, and the two rotating machine guns actually flipped down from the top, and the muzzle of the black hole was aimed at them at once, and the laser laser quickly projected a line of English characters - Pass .wo

d (password)!

"Oh no! this is a two-factor authentication ......"

Colleen's face changed dramatically in an instant, but even if she didn't say Chen Guangda, she understood, if she entered the wrong password, she would be like this group of American soldiers, and she would be directly bombarded by the machine gun, but before her words fell, she suddenly heard someone gloating and laughing: "Welcome to the death gambling scene, the bet is your life......"
