Under the temptation trend of the biochemical weapon M4A1-S, Chen Ye suppressed the eagerness in his heart and slowly walked towards the bottom of the guardrail stairs.

A real gunman can maintain a calm heart at all times, but it can be seen from the surprise and excitement that Chen Ye showed when he took over the Biochemical Tang Knife before, he is not a real gunman, and he can't maintain a calm heart. In the same way, he is not a real gunman now, because he does not maintain that calm heart when he knows the existence of the biological and chemical weapon M4A1-S. However, what these two points can show is that Chen Ye is not too cold, and it cannot be seen how his marksmanship is.

The left foot left the last stage, and then Chen Ye walked through the neatly arranged culture tanks. Out of the corner of his eye, he inadvertently glanced at the deformed mutant embryos in the liquid fluid on both sides, and an inexplicable sense of fear surged in his heart. With that inexplicable sense of fear, he quickly walked through the neatly arranged tanks to the metal gate leading to the third floor of the biochemical laboratory. Immediately, the metal gates slowly opened one by one under Bailey's control, and in the gap between the openings, Chen Ye pulled out the attribute interface where he held the biochemical weapon Zhonghua Tang Knife.

......

"Is this a biological weapon?" Chen Ye sighed heartily in his heart. With his current attack power, he is enough to kill elite zombies who have reached the fifth level awakening stage with one sword, and if he uses the piercing skill, the elite zombies of the seventh level awakening stage cannot be stabbed. And if these players who are still afraid of the zombie elite in the fourth-level awakening period are unfortunate enough to see it, it is hard to imagine how far the scene will develop.

"Warning! Warn! TH-type biochemical weapons are about to break through the defensive shield! ”

However, at this moment, the alarm sound that sounded from the sky above the biochemical laboratory suddenly came, and immediately pulled Chen Ye back to reality in his sigh, tensed his nerves, and suddenly raised his mental attention to the strongest state, and then looked at the floodgates in front of him layer after layer with great nervousness, and the hands holding Tang Dao couldn't help but tighten.

When the last gate was completely submerged into the ground, and the corridor leading to the third floor appeared, the TH biochemical weapon that Chen Ye expected did not appear, and the white metal wall in the brightly lit corridor was like the white snow droplets on the top of the Alaskan Snow Peak, and the two sides of the wall were inlaid with two huge transparent glass covers, and the dried blood stains infected most of the glass cover on the right side, which was in stark contrast to the metal wall that was not dripping dust.

"Boy, the defensive shield is about to be broken by the 'Angel', run straight ahead, and then turn right to reach the central main control room." Bailey's voice was also heard abruptly when the gate was completely submerged.

Chen Ye exhaled deeply, slightly loosened his tense nerves, and suddenly rushed in with an arrow step, holding the Tang knife, and the mother zombie followed behind with a wail.

The sound of the wind whirred in his ears, and Chen Ye immediately ran at full speed in the brightly lit corridor. Shortly after he ran out, a heart-piercing siren sounded again over the hallway.

"Warning! Warn! The TH bio-weapon has broken through the defensive shield and is now moving towards the fast-running unit. ”

As soon as the sirens fell, a loud screech and the sound of the building being destroyed followed. Chen Ye, who was running at full speed, couldn't care about the series of movements coming from the left side of his body, he just blindly ran towards the front of the corridor, because he knew clearly in his heart that only when he ran to the central control in the shortest time to obtain biological and chemical weapons, could he have a glimmer of life. Who knows, the next alarm sounded, directly obliterating Chen Ye's vitality and plunging him into endless despair.

"Warning! Warn! The lab passage is about to be completely blocked in a minute, so ask the researchers to evacuate quickly, and the countdown will turn on 60! ”

The laboratory passage in the alarm is the entrance to the third floor of the laboratory, and the first gate that has sunk under the passage has been slowly raised by the alarm. With Chen Ye's current position, it was obviously impossible to turn back, originally he wanted to withdraw to the second floor of the laboratory immediately after obtaining the biological and chemical weapons. With Bailey's hand, no, to be precise, he killed the 'Angel' with Bailey, but he didn't expect Bailey to block the passage at this time, which undoubtedly made him fall into a helpless place.

"Damn it, slut Bailey!" The sudden rise of anger made Chen Ye couldn't help but scold.

In the next second after the scolding, the three-pronged mouth that Bailey said appeared like a life-saving straw, without the slightest hesitation, Chen Ye turned around and entered the right passage, and at the same time, a command was silently transmitted into the brain of the mother zombie who was beginning to become conscious.

"I'm his slave!"

After the mother zombie let out a high-profile wail, it rushed towards the left side of the passage, and after the words [Furious Acceleration] jumped above its head, its speed suddenly increased, and then it became farther and farther away from Chen Ye's back.

Feeling the sound of running fading away, the pressure in Chen Ye's heart eased slightly. His purpose in doing this was just to give the mother zombie a little more time in front of the 'angel', even if it was five seconds.

If the 'Angel' really did what Bailey said, and the two alien fighting beasts were not his opponents, then the situation would be serious.

However, what Chen Ye didn't expect was that soon there was a three-way crossing in front of him, without Bailey's guidance and no road signs. But the decision to turn left or right immediately flashed through his mind, and in the moment of screaming, he could only rely on luck that had always accompanied him to make a decision. Two seconds later, his form began to turn to the left, heading towards hell he didn't know about.

However, this time, luck did not accompany Chen Ye again, when he ran to the end of the road, the door of the central control room did not appear, and only a scene that shocked him was extremely shocked. The metal wall in front of him was inlaid with a huge see-through glass, and in the glass lay a white female body, a giant-like graceful body, slender and delicate nails, and long black hair flowing in the culture medium, all of which interpreted that she was the 'angel' in the research diary.

And it was such a wonderful picture like an angel descending that made Chen Ye frightened in place. He couldn't imagine that this so-called angel could have the ability to compete with two alien fighting beasts, even if her body was close to three meters, even if her skin showed an unusual sickly white, but this did not mean that she had amazing combat power.

"Is this an angel?" Chen Ye looked at the 'angel' in front of him and sighed from the bottom of his heart, "There is actually another one here." ”

"Angel TH-5 successfully fused with the virus, is it activated immediately!"

Suddenly, an operation interface flashed on the perspective glass, and a row of small red letters jumped out. At the bottom of the user interface, there is also a display that says 'Connect to the central control room and activate it in the central control room'.

Chen Ye chose the latter to activate in the central control room. After choosing, he immediately turned around and ran in the direction he came. And when he appeared at the fork again, a system prompt came from the summoner's interface.

Bite! The mother zombie you summoned was killed by a TH-type biochemical weapon.

At the same time, the scream of the TH-type biochemical weapon symbolized victory sounded.
