As for how Chen Ye determined the location of the mutant creature with the mind control skill, it was related to his exploration of the entire first layer of the biochemical laboratory. After nearly two hours of crawling through the ventilation ducts, he had a preliminary idea of the general layout of the first floor of the biochemistry laboratory.

The biochemical laboratory on the first floor is roughly composed of four sections, the armed guard station, the general staff area, the researcher recuperation area, and the special personnel villa area, which is also interspersed with some entertainment and medical facilities. Each plate is covered with an astonishing number of infected zombies, among which the zombies in the special personnel villa area have the highest awakening level, most of them are elite monsters in the ninth level awakening period, and the rest are mother mutant creatures.

In the room in the plate, Chen Ye found that except for the room that he entered first, which was the most tidy, there were 3 to 4 zombies in the rest of the rooms, and they were filled with a faint bloody atmosphere. And he didn't find any mind-manipulating mutant creatures in these rooms and aisles, which had to make him wonder where the mind-manipulation would be, and then he thought of the neater room he had entered in the first place.

The mutant creature with the ability to control the mind has become a big problem for Chen Ye at this time, and if it is not solved, then there will be no room for the mother zombie to exist. Therefore, in any case, it is necessary to clear the major problems in the heart first, even if it is to use the Type 92 pistol.

However, as soon as Chen Ye climbed back to the ventilation duct of the previous researcher's residence, a crisp sound of a wardrobe opening suddenly sounded, which couldn't help but make him stop, followed by slow and lengthy footsteps, coming from far and near.

When Chen Ye heard this, he immediately turned off the night glare and infrared sight on the Type 92 pistol, and then cautiously crawled to the skylight. At the same time, the right hand turns back to the back to remove the normal bow, and the left hand pulls out a functional arrow from the quiver, then winds the arrow and removes the special coating pouch from the arrow. In this series of actions, Chen Ye was extremely cautious, for fear of making a little noise and startling away the spirit-controlled zombie. Then he poked his head out and looked out under the skylight.

The field of vision begins to adjust to the darkness, and the things under the room take on a blurry black shadow. At this moment, the sound of hurried footsteps suddenly appeared under the skylight, and a black shadow also stood and flashed.

Sou!

Seeing this, Chen Ye instantly pulled the trigger of the bow and crossbow, and the winding arrow immediately shot out, and the sound of the arrow tearing the flesh sounded. I have to say that Chen Ye is lucky, and luck is particularly important when he hits the target just by feeling without any crosshairs.

Immediately after being attacked by the arrow, the shadow let out a low wail, and then jumped to his feet and grabbed his hand towards the skylight, trying to attack the attacker. However, the height problem can only make the tip of its hand just touch the edge of the sunroof.

After Chen Ye heard the subtle sound of arrows entering the flesh, he was overjoyed, and quickly put down the ordinary bow and crossbow, raised the 92 pistol, and the strong light at night was turned on, and the thumb-sized light flew out, and in the blink of an eye, it fell on the jumping mutant creature.

It was a female zombie, dressed in a neat white pajamas, with a decaying face and pale skin like most zombies. The arrow smeared with [Lizard Marrow] stuck in its right shoulder, and the number of red wounds at 8 points per second floated above its head. Chen Ye threw an identification technique downward, and the attribute book of the female zombie was immediately generated.

Monster Name: Mother Mind Zombie (Level 9 Awakening Period)

HP：2000

MP：400

Attack: 235-270

Defense: 200

Speed: 10

Jump: 2.0

Skill: Mind Manipulation LV3 (Skill Description: You can manipulate the mind of mother-level zombies below the ninth level awakening period, and the number of controls is 3.) ）

Description: One of the first researchers to flee after a virus leak in a biochemical lab. However, the virus lurks in the researchers' bodies silently, and even the finished vaccine cannot resist the erosion of biochemical viruses, which have completely mutated.

......

"Sure enough, it's mind manipulation!" After Chen Ye checked the attributes of the mother's mind zombie, he sighed secretly in his heart. He then turned on the infrared sight, and when the red crosshair landed on the opponent's head, the trigger clicked.

Bang! 350！

The pitch-black muzzle flashed a rare light, and the disemboweled bullet flew towards the mind zombie at a speed of 160 meters per second, and an iron-red line of fire suddenly appeared in the thumb-sized strong lamppost, which flashed and disappeared at the center of the opponent's eyebrows.

Bang! 236！

At this time, Chen Ye used the Type 92 pistol to shoot a single burst shot, and quickly pulled the trigger again one second after the first bullet was discharged, and the interval of one second was the time to pull back the slightly deviated crosshair, so that the second bullet could fly along the trajectory of the first bullet. Often, after the impact of the first bullet, the target's body will hesitate in place for a second. Therefore, after the next second, the second bullet arrives as scheduled, and the target will hesitate again. With proper marksmanship, it's easy to lock monsters in place.

Of course, a sharpshooter with precise gun control can easily do this. This style of play in CSol's biochemical mode is called 'Dead Shot'. The firearms and weapons provided by the system can best embody the 'fixed body shooting', if it is a light company sniper in the sniper rifle family, it is difficult for the rest of the weapons to achieve this effect. However, since Chen Ye can use a Type 92 pistol to shoot a 'fixed corpse', this is enough to show that his gun skills are extraordinary.

After firing two bullets in a single shot, Chen Ye stopped and turned off the night glare and infrared sight, and then, he sat at the mouth of the ventilation duct and waited, waiting for the [Lizard Marrow] to have a total of 1440 points of continuous damage effect, which is why he would stop after firing two bullets, saving bullets is one of the compulsory subjects for every gunman.

......

About three minutes later, a painful wail was heard, announcing the end of the mother's mind zombie. Chen Ye also turned on the night bright light at this time, shining on the fallen corpse and the two golden lights faintly flashing under the corpse, and then jumped down and groped beside the corpse.

Equipment Name: A-Rank Urban Combat Shoes

Rank Required: Soldier

Defense: 35

Speed: +1

Enhancement: Speed Mastery +1 (Note: Speed Mastery +1, which increases speed by 0.5 meters per second.) ）

Durability: 130

Description: One of the A-level city transfer .......

Chen Ye looked at the black military shoes in his hand, and was overjoyed, he didn't expect to encounter the A-level urban combat suit parts here, and the attributes were surprisingly gratifying, not to mention the 35 points of defense, the most important thing was the speed increase value of 1.5 meters per second. I couldn't wait to replace it, pulled out the attribute interface, and the speed had soared to a sharp value of 11.6 meters per second.

"Not bad!" Chen Ye couldn't help but exclaim. Then crouch down again to pick up another item.

Item Name: Evolutionary Nodules I (Advanced)

Description: The devouring virus that gradually condenses in the brain of mutant creatures, and players can exchange this item for corresponding gold coins and supply equipment in the base.

"That's not bad, at least 6 gold coins, or a base bullet." Chen Ye praised again and again.

The two pieces of equipment left by the mother mind zombie in the ninth-level awakening period made Chen Ye very satisfied. However, what satisfies him the most is that after successfully killing the Mind Zombie, he can summon the Mother Zombie to fight together. For Chen Ye, that potential and powerful hole card is used to destroy the mutated creatures on the first layer, and it is especially important to burst the electronic pass card that opens the door of the second layer of alloy.
