The first floor of the biochemical laboratory is located ten meters underground, where there is no light, only darkness and gloom.

Dark, confined space, such an environment, it is easy to make people's hearts rise up to the fear of the unknown, not to mention, everyone who enters this place knows that under their feet is a biochemical laboratory where murder and wealth coexist.

Two bolts of tactical flashlight swayed up and down in the dark, and there was no elevator, so everyone had to take a circular spiral staircase.

Ye Feng walked at the front of the team, and his extremely standard posture of marching with a gun made the Proud Fire Shadow Leader who followed him more and more convinced that the man in front of him was a soldier in the real world.

He really wanted to confirm with the blood mist at this moment whether his guess was correct, but he knew that at this moment, the most important thing was to keep quiet, and any noise might attract mutated creatures that might exist in the dark.

Drops of sweat gradually condensed on the forehead of the Proud Fire Shadow, and when he entered the biochemical laboratory again, he was still very nervous, and he couldn't help but feel a chill down his spine when he remembered the ecstasy he had been chased by the licker before.

"I don't know, are there any biochemical weapons down there?" The Proud Shadow muttered inwardly.

Soon, Ye Feng went down to the first floor of the biochemical laboratory, and through the irradiation of the tactical flashlight, it seemed that there was only one passage in front of him.

Let's go!

Ye Feng glanced back at everyone, but unexpectedly found that the expressions on the faces of the Proud Fire Guild players were a little unnatural, as if they were very nervous.

"Scared?" Ye Feng couldn't help but smile and asked in a low voice.

The Flame Shadow raised his right hand, fanned it against his face, and replied, "The air isn't very circulative here, it's a little hot, you know. ”

"Really?" Ye Feng laughed and didn't break it, after thinking about it, he still reminded everyone: "Everyone be careful." ”

"Hmm." The crowd replied in a whisper.

Immediately, the team continued to move forward, and through the irradiation of the tactical flashlight, the layout and structure of the first floor of the biochemical laboratory emerged.

It can be seen that the original intention of the rooms on this floor is to escape, and there is a skylight pipe at the top of each room that links to the outside world, so that in the event of an emergency, the research staff living here can escape through the skylight pipe.

"Shadow, last time, you searched the first layer, there shouldn't be anything missing, right?" At the entrance of the second floor of the biochemistry laboratory, Ye Feng stopped and asked.

Fourth-order biological and chemical weapons, according to normal procedures, are the most likely to appear on the fifth layer of the laboratory, but no one can guarantee that the weapon will not be taken to other layers by the armed clearance personnel of the laboratory, or by the people in charge of NPCs, Ye Feng's purpose of asking the shadow is based on this premise.

The Proud Fire Shadow nodded and said, "Last time, we stayed here for two hours before leaving, it can be said that any room has been rummaged, if there is a fourth-order purple biochemical weapon, then I won't call you, the weapons are all in hand, why take this risk." ”

"Then we'll go down." Ye Feng glanced thoughtfully at the Proud Fire Shadow and said.

The road to the second floor of the biochemical laboratory is still a circular spiral staircase, but the height is five meters more than the ten meters from the first floor to the ground.

And looking down from the stairs, you can see two hollowed-out giant glass culture tanks, which stand in the underground space about the size of a football field, and with the giant culture tank as the center, spread out to the surrounding areas, there are small glass studios, studios, microscopes, injection test tubes and other chemical experiment equipment, all available.

"The items are neatly placed and there are no traces of destruction, and two things can be seen from the appearance, one is that when the Biochemical Alliance was evacuated, it was in order, which can show that their working experimenters are extremely high-quality and have been strictly trained. Second, the licker has not been to this floor, and the first floor you encountered before should have been entered through the elevator. After stepping on the ground on the second layer, Ye Feng analyzed his speculation to everyone.

"And then, Bloodmist Moss?" Battle Sky Wolf teased.

"Then, when you search, let's be careful." Ye Feng said.

When searching for the second layer of the biochemical laboratory, Ye Feng didn't have much hope in his heart, he could find a fourth-order purple biochemical weapon here, but in line with the principle of leaving no regrets and not missing out, the search was still necessary.

However, it didn't take long for 'Bang~! With a bang, the sound of glassware falling to the ground and shattering sounded very crisply behind him.

"Hopefully this voice won't alert the mutated creatures below." Ye Feng turned around and hit the tactical flashlight beam near the body of the arrogant tiger, he did not shine on the latter's body, because the strong light acted on a nervous person, which was likely to cause this person to lose control of his emotions.

"Tiger, what's going on?" The low voice of concern from the Proud Fire Shadow quickly passed into Ye Feng's eardrums.

It was at this moment that Ye Feng was keenly aware of the surrounding environment, and suddenly there was a strange sound of walking.

"Are there any mutated creatures?" Ye Feng closed his vision and used his hearing to search for a target for the first time.

"There's a headless corpse here, and the scars on the body are supposed to have been caused by the lickers." The arrogant tiger replied in a trembling voice, almost losing his voice: "In this layer, there are also lickers. ”

"It's close, it's close, it's where it is." Ye Feng opened his eyes suddenly, and at the same time, the gun in his hand quickly moved to the position that his hearing locked.

The tactical flashlight was released, and only a mutated creature with limbs lying on the ground and a long tongue sticking out of its mouth had already taken an attack posture against the arrogant tiger, as if it would launch an offensive after a second.

"It's very similar to a licker, but it's incomplete, like a deformed test subject that came out too early." This was Ye Feng's first impression when he saw the mutant creature, and after being irradiated by Ye Feng's tactical flashlight, the mutant creature instantly retracted its attack posture and turned around and jumped into the darkness.

"The prey saw the hand, but because of a little change in the external environment, it was decisively canceled, this mutated creature has a certain amount of wisdom." A sense of uneasiness rose in Ye Feng's heart, and then he shouted to everyone: "The people who are nearby, lean on each other, this mutant creature is not a licker, but it is more difficult to deal with than a licker." ”

After finishing speaking, Ye Feng quickly leaned towards the location of the arrogant tiger.

"Are you alright?" Ye Feng asked.

The Flame Shadow swallowed the saliva in his throat for a moment before replying, "It's okay. ”

Ye Feng patted the shoulder of the arrogant tiger and said, "Anla, it's okay." ”

Soon, everyone was together.

"Boss, what kind of monster is it?" The Pyrophoric Wolf asked.

Ye Feng: "It's very similar to a licker, but it's much smaller, has a certain amount of wisdom, and knows how to choose and choose its prey." ”

"So what now?" The Flame Shadow then asked.

"Let's fire indiscriminately!" Ye Feng replied. In the past, because their own personnel were scattered all over the second floor, if they were shot, it might cause accidental injuries, but now everyone is back to back, gathered together, and the muzzle of the gun is controlled outside, so there is no need to worry about anything.

"Listen to me!"

"Three!"

"Two!"

"One!"

"Fire~!"
