The third layer of the biochemical laboratory, the virion experimental area, has countless giant culture beds, but unlike the second layer, most of the culture tanks on this layer are metal barrier structures, as if to prevent the experimental subjects from escaping out of the culture tank, but the unfortunate result cannot be avoided after all.

Eventually, the subject broke free from the metal barrier structure and escaped from it in a way that no one could have imagined, as if no one could have known when it was going to rain.

"Why didn't the Biochemical Alliance get rid of them when they were withdrawing?" A question rose from the bottom of Ye Feng's heart, making it difficult for him to understand. Especially after he saw the licker in the culture tank that had not yet taken shape, this kind of incomprehension was even more incomprehensible.

However, after thinking about it, it seems that leaving mutated creatures in the human world has always been the style of the Biochemical Alliance, otherwise, it would be impossible to reasonably explain why the Biochemical Alliance would create a virtual global Resident Evil accident.

Everyone searched around, but there was no potential threat, no supply ammunition for third-order pseudo-biochemical weapons, and no fourth-order biochemical purple weapons.

Everyone's eyes naturally turned to the fourth layer of the biochemical laboratory, and before the laboratory under the shadow of the proud fire, it was said that in this layer, there may be mutant creatures at the level of small bosses.

"Let's go, it's all here, if you don't go down and see, how can you do it." Fighting Regulus said.

Ye Feng still took the lead, walking at the front of the team, all the way still swinging down the staircase, twenty meters high. Counting the previous first, second and third floors, Ye Feng and others have gone 60 meters underground.

Going down to the bottom of the corridor, there are two roads in front of Ye Feng, one to the left and one to the right.

"Do you want to go separately, or do you want to do it together?" The Shadow of Pyrocidation always sees the source of the problem first.

"Let's do it together!" Ye Feng gave the answer and said, "It's just a matter of left and right!" ”

"When life breaks through the shackles, there is no turning back, whether to the left or to the right, there is only one end, the abyss and hell."

Battle Xuanyuan picked up a piece of sticky note paper and said in a broken voice. After reading it, he looked up and saw that Ye Feng was staring at him, and the Fighting Heavenly Wolf Hell and others were staring at him.

"I took it off the wall." Battle Regulus hurriedly explained.

"Can you not shake the morale of the army at such a time?" The Battle Sky Wolf said angrily.

Ye Feng thought about it carefully, and suddenly had an inexplicable feeling.

"Xuanyuan, you are reading it once, in a sad tone."

"Ah~ Do you still want to read it?" Battle Xuanyuan was stunned for a moment, and when he saw Ye Feng nodding, he had to pretend to cough a few times, and read in a sad tone: "When life breaks through the shackles, there is no way back, whether it is left or right, there is only one end, the abyss and hell." ”

"Do you hear something?" The Battle Sky Wolf asked curiously.

"Nope." Ye Feng admittedly and said, "That's to the right!" ”

The passage was very narrow, allowing only three people to pass in parallel, Ye Feng walked at the head, his left hand side was a stone wall, and his right hand side was a floor-to-ceiling glass window.

Outside the glass window is the space on the fourth floor of the biochemistry laboratory, which is about the size of two football fields, divided into four areas, each separated by a heavy metal wall.

Standing in the passage and looking down, it can be intuitively seen that the four areas that are separated, like the Colosseum, must be the place where the researchers of the Biochemical Alliance observe the combat effectiveness of biochemical weapons.

"There are two lickers there, and they've just died!" The Pyropus Tiger found two more corpses, just as he had found headless corpses on the second floor.

"At such a distance, the fatal wound can still give people a shocking sense of immediacy, and I don't know how ferocious it must be to kill the mutated creatures of the lickers." The Proud Fire Shadow looked at it for a while, feeling frightened.

"Judging by the wounds, it's a lot like an enhanced version of the Licker." Battle Xuanyuan began to learn from Ye Feng, and looked at it at a deeper level through the manifestation phenomenon.

Ye Feng said in a deep voice: "Don't speak, pay attention to your feet." ”

Everyone was puzzled, and just as they wanted to ask, they heard Ye Feng say in a very low voice: "In the four Colosseums, no mutant creature was found to kill the licker, which can only mean that this mutant creature is hiding in our blind spot." ”

"Turn off the tactical flashlight and listen with your ears."

Bang~!

Bang~!

The tactical flashlight turned off, and the darkness fell like a tide, and in the silence that followed, everyone seemed to be able to hear each other's heartbeats.

No one spoke, not even the sound of gasps, which was very low. Everyone pricked up their ears and listened to what was going on around them.

A minute passed quickly~!

Five minutes are gone in a blink of an eye~!

Ye Feng didn't speak, and the Proud Fire Shadow and Battle Xuanyuan and the others had to be patient, continue to wait, and continue to listen.

Fifteen minutes later, the Battle Wolf felt his legs go numb, and then, he thought he was careful to move a small step.

It was this small step he took, and there was a sudden sound of several large steps under the floor, and at the same time, there was a slight vibration of the floor.

The Battle Wolf instantly felt his heart rise to his throat, and he didn't take a small step.

Bang~!

Ye Feng turned on the tactical flashlight all of a sudden, and when the strong light swept over everyone's faces one by one, he saw that everyone's faces were covered with nervous sweat.

Immediately, Ye Feng aimed the light at himself and began to gesture to everyone.

The people who were so depressed by the heavy atmosphere that they didn't dare to come out looked at Ye Feng's gestures seriously, and finally nodded knowingly.

The muzzle of the Whirlwind M4 poked out and aimed at the Proud Fire Tiger a meter in front of him.

"Flashman." Ye Feng roared angrily and pulled the trigger at the same time.

The green line of fire roared out in an instant, and the third-order enhanced bullet with LV2 penetrating power disappeared through the floor in an instant.

The moment the gunshots rang out, the arrogant tiger turned around and ran, the green line of fire following its heels, extending all the way.

Oh~!

The beast's screams rang out, and Ye Feng, who heard this, turned to run forward, shooting all the way.

So, on the fourth floor of the dark biochemical laboratory, such a thrilling picture appeared.

The Proud Fire Shadow led eight players all the way through the narrow passage, and Ye Feng, who was less than three meters away, was right behind them, shooting the ground with a whirlwind M4 all the way.

At this time, if you can pull your vision to the opposite side, you can clearly see a mutant creature about twice the size of an ordinary licker, hanging upside down on the wall below the passage, and the green line of fire pierces through the wall, and then hits the body of this mutant creature.

The strangulation and penetration ability of the third-order bullet could not be ignored even if it was a biochemical weapon, so the mutated creature hanging upside down on the wall let out another roar and fell to the ground.

Touch~!

After hearing the dull sound of flesh hitting the ground, Ye Feng stopped pulling the trigger, he looked at the arrogant fire shadow, and said, "Biochemical grenade, throw!" ”

The Proud Fire Shadow Eye was also quick, opened the safety of the biochemical grenade, and threw it into the hole in the floor that was pierced by the third-order bullet.

3~！

2~！

1~！

The biochemical grenade exploded violently, and the dazzling green flames lit up the entire space.

A huge licker roared out of the green flames, with an unextinguished grenade afterflame on its body, and jumped up the wall, like a gecko, and rushed towards Ye Feng.

"Look for death." Ye Feng frowned, and the action of changing the magazine in his hand showed no signs of slowing down.

Bang~!

The bullet was loaded again, Ye Feng pushed the bolt, aimed at the huge body of the licker, and when his breathing was adjusted, he had already pulled the trigger.

Bang~! Bang~! Bang~!

Once again, the green line of fire poured out from the muzzle of the smoked gun.
