In front of the huge pit formed by the collision and destruction of the zombie giants, Chen Ye slowly put down the Type 92 pistol, and then began to make the last preparations to enter the biochemical laboratory in the reflection of the strong lamppost at night.

Remove the quiver containing the three multi-purpose arrows hanging on his back, then take out the arrows contained in them one by one and place them on the ground, and then take out the three [Lizard Marrow] prepared at the base of the Novice Village from the backpack.

The carefully processed [Lizard Marrow] has been placed in a special paint bag by NPCs, and when used, simply put the paint bag on the arrow and remove it when shooting. By that time, [Lizard Marrow] would have completely encroached on the arrowheads. Although [Lizard Marrow] is not as poisonous as [See Blood Throat], it is expensive in that it lasts for a long time, and it is undoubtedly a painful process for the prey to end its life in a prolonged fear of death.

Chen Ye didn't like the process, nor did he like to be the maker of the process. He admired the feeling that life and death were only in a moment, as if when he killed mutant creatures, he always liked to attack the opponent's head, because that would not only cause double damage, but also kill the opponent in the shortest time and make them die happily without a struggle for death, which was the result that Chen Ye was most willing to see. But now, for the sake of the legendary bioweapon, he has to go against his will.

Carefully place the [Lizard Marrow] Paint Bag on the multi-purpose arrow, then put it back into the quiver and hang it on your back. After doing this, Chen Ye picked up the Type 92 pistol again, looked at the maternal zombie, and then gave an order.

"Mother, let's parachute!"

"I'm his slave!"

The mother zombie let out a wail and jumped directly into the pit, and the subsequent impact damage information showed that the depth of the pit was at least five meters.

Without the slightest hesitation, Chen Ye also jumped into the pit after receiving the impact damage information of the mother zombie. After 0.5 seconds, he felt his feet on the soft ground, and the bright red carpet showed the reason for the softness of the ground.

And at this moment, the dense zombie wails suddenly came from both sides of the body, and the situation immediately fell into an extremely critical state, Chen Ye didn't even have time to look at the position he was, and a dodge jumped into the room on the right side of his body, followed by the mother zombie.

After seeing the mother zombie come in, Chen Ye immediately closed the door. Unexpectedly, at the moment when he pressed his body against the door, a cold wind struck from behind, followed by a piercing pain, and the number of red injuries of 150 points floated above his head.

"Mother! Above! ”

Chen Ye, who was against the door, shouted, endured the pain behind his back and twisted out the anti-theft latch, and then took the soldier's water bottle and poured it hard. And just when his qi and blood had just recovered to full value, another cold wind struck, and with a 'poof' sound, the number of red injuries of 150 rose again.

"Mother! Above! ”

Chen Ye turned around, wanting to take a closer look at the mutant creature that could only attack him under the attack of the mother zombie. But the result was that he was stunned to find that the killing hand of the mother zombie was rapidly attacking him. In other words, it was his summoned zombie who launched the attack just now, not other mutated creatures.

"Flesh and bone sacrifice!"

Seeing that the killing hand of the mother zombie was about to attack, Chen Ye spit out three words directly from his mouth. In an instant, the body of the mother zombie exploded in the blink of an eye, turning into a pile of blood-colored data and dissipating.

Bite! You successfully use the [Flesh and Bone Sacrifice] skill on the Mother Zombie and gain 350 Qi and Blood.

After the system prompts a message, the qi and blood will immediately return to the full value. However, Chen Ye was not happy because of this, but his heart became extremely solemn. As soon as he entered the biochemical laboratory, he didn't even step on the carpet to get hot, and he lost the biggest hole card mother zombie in the entire exploration process, which was undoubtedly a blow to morale. As for why the mother zombie was abnormal just now and suddenly attacked him, it can be known in Chen Ye's next slightly surprised words.

"There's actually a mind-controlled mutant creature here."

As the voice fell, Chen Ye immediately fell into the next exploration plan. If you want to explore the entire biochemical laboratory smoothly, you must have the powerful hole card of the mother zombie. If you don't get rid of the mutant creature that can use the mind control skill, then the mother zombie will not be able to control it normally, and it will only be a burden to summon it, which will not only delay but also be rebelled by the mutant creature.

And the mutated creature that can only use mental manipulation skills is at least the existence of the mother body of the eighth-level awakening period, and even the ninth-level awakening period is unknown. The existence of this level is not a big problem for Chen Ye now. At this time, the biggest problem he faced was how to save as much ammunition as possible and safely avoid the siege of the dense zombies outside the door, and then find the location of the mentally controlled mutant creature.

Therefore, Chen Ye did not plan to open the door and fight the screaming zombies outside the door face-to-face, or shoot and kill them with a Type 92 pistol. Although the Novice Village base exchanged the Evolutionary Nodule for a base number of 92 pistol ammunition, one base number is only four magazines, and based on the 15 rounds of the Type 92 pistol, he is now only 60 rounds. And these 60 bullets are used to deal with the final boss, and they can't be extravagant on those mobs.

The strong lamppost on the Type 92 pistol moved quickly in the room, and finally stopped on the skylight in the center of the room, and Chen Ye couldn't help but be happy. I thought to myself: "The ventilation duct should run through the entire basement, responsible for the ventilation of the room, and walking through the ventilation duct by yourself can not only effectively avoid the zombies outside the door, but also explore the entire biochemical laboratory, and by the way, solve the mutant creatures that can only use mind control skills." ”

Chen Ye thought as he began to move the seats in the room and place them under the skylight, preparing to build a platform into the ventilation duct. Fortunately, the room he was in was relatively tidy, and there was not a single mutant creature, so his construction work went so smoothly, and soon a platform was built.

Although the violent impact sound from outside the door was breathtaking and terrifying, for Chen Ye, who had half of his body drilled into the ventilation duct, the violent impact sound was like a cloud of smoke, and he was not afraid.

With the secret thought in Fang Cai's heart, Chen Ye began to crawl up the entire ventilation duct, missing room after room under him, looking at the zombies who were sighing and wailing under the skylight, he would have an inexplicable sense of security in his heart.

However, an hour later, when Chen Ye ran through the entire ventilation duct in the basement, he came to two most crucial conclusions.

The first conclusion is that his current location should be the first floor of the biochemical laboratory, because from the furniture arrangement of all the rooms, it can be seen that this is only a collective dormitory for biochemical researchers. The biochemical experiment area should be under the collective dormitory, and Chen Ye designated it as the second floor of the biological laboratory, and if you want to enter the second floor of the biochemical laboratory, you must open the still shiny metal door. As for the method of opening the metal door, you need to gather three electronic access cards, and Chen Ye now only has a green electronic pass card in his hand, and there is still a red and white electronic pass in his hand.

And the second conclusion, which was also very wrong for Chen Ye, was that the mutated creature that could use the mind manipulation skill was actually somewhere in the researcher's dormitory where he had just entered the ventilation duct.

PS: Thank you for the VIP reward of the book friend 'it's okay to keep a low profile', and I would like to express my gratitude tomorrow.
