The entire biological institute is enclosed by an aluminum alloy fence more than five meters high, with barbed wire with blades on the top, high-voltage warning signs on the wall, and the only entrance is the gate.

Just as he approached the door, Zheng Dong keenly felt that there were not only a few guards behind the gate, but the nervous breathing of dozens of people, but the security guards on the watchtower showed a careless look.

Surely there is something wrong with this strong contrast?

Zheng Dong took out his mobile phone and dialed Shu Shao's phone, "When you get to the door, turn the camera inside the gate for me." ”

"Roger!"

His mobile phone clearly shows the situation inside the gate, at the entrance, not ordinary security guards, they are all veterans about thirty years old, from the location of the ambush, the firepower configuration, it can be judged that they are battle-hardened mercenaries.

The walkie-talkie was tuned to 03, Zheng Dong called the other team members, "1, 3, 6, 7, sniper group, we will pick up the enemy immediately, the enemy has an ambush, pay attention to the surrounding situation, 4, 5 support groups pay attention, 5 grenades are fired continuously, coordinates 03---15---09, block the enemy who goes out, start!" ”

------With the firing of 5 grenades in a row, the mercenaries in ambush in the courtyard were dizzy by the sudden grenade, scurrying around, looking for cover again, and more than a dozen people were blown to the ground.

Through the camera controlled by Shu Shao, Zheng Dong's mobile phone was like a live broadcast, and among these people, he saw a familiar figure, Ryunosuke. As soon as the bombardment stopped, he stood in the courtyard and shouted, directing the remaining mercenaries to rush to the door.

"At the door, armor-piercing/anti-personnel shells, two, random shots, I'm in." After a brief order, Zheng Dong lurked near the door.

The headphones were connected to the phone, and he said to Shu Shao: "Help me open the door inside, the route." ”

“Okay。”

As soon as the gate opened, the mercenaries seemed to know the location of No. 4 and No. 5, and the first person to rush out accurately covered the fire on the hill, and at the same time, due to Zheng Dong's early warning, a grenade exploded accurately in the crowd, Zheng Dong got up and ran to shoot, and the two people on the entrance watchtower were knocked down instantly.

Another grenade, extended shot, fell into the courtyard, the mercenary who followed closely was blown up, Zheng Dong ran as fast as the wind, and when he swept past those people and corpses, he saw Ryunosuke, frowned vigorously, and saw the aura behind him.

Half is white, half is light blue, I have seen it on the mirror in the bathroom, although I have a halo, but only one-third of the halo is light blue, and the rest is still white, so Ryunosuke is equivalent to the middle stage of light blue, and he is still in the early stage of light blue.

In terms of strength, he is obviously lower than Ryunosuke at present, Zheng Dong has no problem fighting two Ryunosuke in the past, why does his strength improve so quickly, Zheng Dong thought about it, and couldn't help but speed up his pace, before getting the sample, he couldn't fight with him. Taking advantage of the explosion dust that had not dispersed, he quickly rushed to the main building.

"Open the door." Zheng Dong said in a low voice, he can't take care of Ryunosuke, it's best not to find him, otherwise the longer the delay, it is very likely that something will happen.

Shu Shao controlled the camera from a distance, and saw Zheng Dong's actions clearly, when he arrived at the door, the electronic lock code of the door was cracked and opened smoothly, as soon as he entered the room, the door behind him was immediately closed.

The two cooperated very tacitly, rushed to the door, opened the door, closed the door, and went straight to the warehouse, there was no conflict in the middle, his body moved too fast, neither the patrolling security guards nor those R&D personnel noticed that he had come.

Arriving at the warehouse, there were only two guards in the corridor. Zheng Dong slowed down, pretended to pass by, and suddenly attacked when he passed by them, knocking the two of them unconscious with a punch and a hand knife, and the warehouse door was opened by Shu Shao's remote control.

Successfully entered the warehouse, Zheng Dong made a difficulty, a row of vertical freezers against the wall were samples, and in the face of thousands of reagents, Zheng Dong anxiously asked: "Which number should I use?" ”

"Wait a minute, I'm reading their experiment report, I can't enter the database in advance, otherwise they will find out, the network will be disconnected, and the data will be sealed, now I read the report, the report has more than a hundred pages, it will take about 3 minutes, there are security guards in the corridor approaching, you have to drag them."

"Okay, 3 minutes." Zheng Dong took two assault rifles and four magazines from the doorman, and checked that he had fourteen pistol magazines, four high-explosive grenades, stun grenades and smoke grenades given by No. 4 and No. 5.

The warehouse was unusual, containing potions and all the experimental samples, the institute alarm sounded, and the corridors on the east and west sides were crowded with security guards probing their brains.

The exchange of fire began with a high-explosive grenade on Zheng Dong's left and right, and the violent explosion caused a large area of cracks in the surrounding explosion-proof glass walls, Zheng Dong did not dare to throw the grenade again, and operated two assault rifles, fired cross-fire, suppressed the opponent's fire, and the surviving security guard was forced to retreat to the corner of the corridor.

At this time, Zheng Dong shot at the enemy attacked by the probe, and as soon as he found that they were showing signs of collective charge, he fired with an assault rifle. When the ammunition was counted, there were two plus four magazines on the rifle, 180 sub-rifle cartridges, fourteen pistol magazines, nearly 200 pistol cartridges, and it seemed that there was sufficient ammunition.

As soon as the guns rang out, the ammunition was consumed extremely quickly, and the special assault rifles, with one strafing shot, consumed half of the magazine's bullets. Thanks to Zheng Dong's accurate shooting, except for strafing, the pistol bullets were not missing, one shot at a time, and the opponent was gradually unable to attack, and the two sides were deadlocked.

Time passed minute by minute, and three minutes seemed to be three years later, Zheng Dong ran out of rifle bullets, and there were still five magazines left for pistol bullets.

"The best sample number is ZL528, freezer No. 4, and other samples and agents can be destroyed." Hearing Shu Shao's voice, Zheng Dong breathed a sigh of relief.

He turned his pistol into bursts, firing seven or eight shots on the left and right, and then threw out a smoke bomb to create the illusion of escaping, and the gunfire rang out on both sides, and then he returned to the warehouse, found Freezer No. 4, found the numbered tray, and found that there were three red reagents in it, all of which were removed and put into an aluminum ice box, and put in a backpack.

Knocking down all the freezers, he found a large barrel of alcohol, opened the lid, lifted it and poured it all over the various reagents scattered all over the ground.

He threw out another smoke bomb, the corridor was full of smoke, Zheng Dong aimed at the door of the warehouse, and shot at the explosion-proof glass with his intuition, the bullets almost hit a point, and soon made a relatively deep hole.

When the smoke was about to clear, he pulled out a high-explosive grenade, threw it into the hole, and hid aside.

There was a loud bang, and the explosion-proof glass wall opposite was splashed with debris, revealing the outside space, and at the same time, he took out the lighter and lit the alcohol in the warehouse, and a large number of reagents quickly ignited a raging fire, Zheng Dong rushed to the opposite side and drilled out of the hole in the blasted glass wall.

As soon as it came out, it was a huge camp, fenced with barbed wire, reinforced concrete, and the camp nameplate also marked the good defects. The monsters locked up in the barbed wire camp of the defective product can be clearly seen, and the nameplate of the defective product is marked with the infected. He understood, and fled to the camp of live samples.

There were two patrols and some R&D personnel between the camps, and after seeing Zheng Dong, the patrol team immediately opened fire, and within a range of twenty meters, Zheng Dong quickly took action, pulled out his left hand with a gun, and his right hand with a mace, almost instantly killing all the patrol security guards.

Before killing the last security guard, Zheng Dong secretly screamed badly, the security guard he had just killed had exhausted the last bullet in the pistol magazine, and there was a security guard on the other side, who had already raised his gun to aim, locking him in the middle of the crosshairs, and he was about thirty meters away, and it was too late for him to change the magazine or throw out the black dragon mace in his hand.

He roared wildly and rushed towards the security guard, however, the other party's trigger was not pulled, and Zheng Dong pierced him in the chest.

Looking at the slowly falling corpse, he found that he had actually broken through, and the teleportation attack range that could only be at twenty meters before, but now it had expanded to thirty meters, could it be because of Immortal Master Chen's transmission? Other than that, there is no plausible explanation.

While he was rejoicing in progress, a man within the glass wall was on the verge of rage.

Ryunosuke has been commanding the battle, after all, he is also flesh and blood, and Zheng Dong's accurate marksmanship makes him very jealous. Seeing that he ran into the camp of live samples, he was completely disgraced, and he had a plan, and said with a cruel smile: "We are about to test the combat effectiveness of these samples. ”

He picked up the walkie-talkie and said viciously: "I order, open the door of the defective camp and release half of it." ”

The person in the central control room asked in surprise: "Sir, that's more than fifty, and our R&D personnel are still inside." ”

"Put."

In the central control room, Dr. Ito sat in a chair, he heard what Ryunosuke said just now, and the security guard who answered the phone looked at him and asked for his instructions.

A young man who looked about the same as him, was a little taller, but did not have a beard, walked up to him and said, "Brother, let me go, clean up this Chinese man, simple." He crushed the teacup in his hand, turned it into powder, and scattered it all over the ground. If Zheng Dong could see him, he would be able to immediately recognize that the person who provoked Zheng Dong in Lu Yujie's Daoist Hall was this person.

"No, release defective products." Ito waved his hand.

Zheng Dong suddenly saw the gate marked with the inferior camp open, and rushed out more than fifty people, in fact, they could no longer be called people, their eyes were gray, and the skin of their whole bodies was also gray and white like that of dead corpses, so they could only walk slowly.

After coming out, they roared, made a "whine" sound, dragged their feet, and pounced on the R&D personnel who were hiding in the field.

Resident Evil!

Zheng Dong's first reaction, when he was staying at home with Du Haiming, he was either watching a movie or playing a series of Resident Evil games, but he didn't expect to see it with his own eyes today, pushing a magazine into the pistol, and he shot an infected person.

He was only knocked back by the impact of the bullet, and then staggered towards him.

Raise his hand and shoot the infected in the head, he falls to the ground on his back, no longer making any movement, it seems that he will die by hitting the head as in the game.

What happens if they bite? Zheng Dong just had this question in his heart, and a person who was knocked down and bitten to death staggered to his feet.
