The three of them quickly reached the center of the area, leaning against the walls of a number of alloy platforms, on which sensational fixed many zombie corpse specimens, and the computer next to each high platform recorded the detailed number of these zombie varieties in detail.

From ordinary secondary biochemical ghosts to biochemical ghosts, swift ghosts, night ghosts, greedy ghosts, stealth ghosts, gun-wielding ghosts, sniper ghosts to red biochemical ghosts, and Hulks, Wu Yi has seen all the types of zombies here, and the strengths, weaknesses and special abilities of these zombies are also marked.

While Wu Yi was carefully inspecting the shrunken zombie corpses, Zhang Qiang suddenly shouted excitedly, "Come and see what this is." ”

Wu Yi hurriedly walked over and saw what Zhang Qiang was referring to, which was a refrigerated storage cabinet made of special materials, and there were ten red potions side by side in it.

Gene enhancement agent type II: black iron three products. Adds 6 points to all stats after use. Requirements: Injected with genetic enhancement agent type I. Notes: The magic potion developed by Nolan on the basis of the ghost virus, so it can increase a small amount of resistance to the ghost virus after use, and can be immune to most elite-level biochemical ghost infections.

Zhang Qiang said excitedly: "Haha, this time it is developed, and it can be strengthened again, and it is easier to deal with zombies." ”

Wu Yi nodded, he immediately opened this storage cabinet, and the magical potion was close at hand.

"That, Brother Wu Yi, Brother Doctor, can I take three potions, I still have two friends, if they can survive, I want to strengthen the two potions for them." Zhang Qiang said with some embarrassment.

"Hehe, I also have three companions waiting for me to rendezvous, I also need to take three more potions, doctor, you take the remaining three potions. I've taken advantage of this point, and I'll get a little less if there's anything I gain in the future, so it's no problem. Wu Yi said.

The doctor smiled and nodded, "I have no opinion." ”

"Of course I don't have a problem with that." Zhang Qiang said with satisfaction.

The three of them quickly finished dividing the spoils, Wu Yi took four potions, and the other two took three, and they both chose to use them on the spot.

While the three of them were happily enjoying the pleasure of strengthening their bodies, because the three of them took the precious potions in the storage cabinet without authorization and activated the guard of the intelligent system, the lights on the walls turned into a strange red, and they flickered wildly, making people know that the situation was wrong at a glance.

Seeing that the alloy wall suddenly cracked, and a thick mechanical arm pushed out a large row of closed cultivation tanks from inside, the three of them were stunned by this astonishing change.

A large stream of gas erupted from the cultivation tank, and then the bulkhead was opened in the roar of the machine, revealing the contents inside, this row of cultivation tanks were full of xenomorph zombies, more than a dozen Hulks, red biochemical ghosts, and dozens of self-detonating ghosts, Wu Yi also saw that the center of the wall was launched a giant cultivation tank, just by that size, you can imagine that it was definitely a big guy inside.

After coming into contact with the fresh air, many of the sleeping zombies were awakened, and they opened their eyes one after another.

"How can there be so many mutated zombies, there are more than a dozen Hulks alone." Being stared at with blood-red eyes by so many terrifying monsters, Zhang Qiang only felt a dryness in his throat, and cold sweat instantly covered his whole body.

"Run!" Seeing that so many high-level zombies were waking up, Wu Yi realized the danger, he yelled at the other two, and then took the lead in running towards the original road.

After being awakened by Wu Yi, the doctor and Zhang Qiang hurriedly followed, and when they ran to the entrance of the area, Wu Yi saw a row of gun-wielding ghosts with submachine guns.

"Close your eyes!" Wu Yi reacted quickly and raised his gun to shoot, and two special bullets, one white and one black, shot out, bursting out with a dazzling white light.

Zhang Qiang and the doctor tacitly obeyed Wu Yi's reminder, and after closing their eyes, they could still feel the dazzling light shining on their eyes.

"Kill!" A simple word, the three of them shouted together, after using the genetic enhancement potion, the three of them have made great progress in their marksmanship, taking advantage of the few seconds when the ghost with the gun was blinded, the three people with a deep sense of crisis played at a high level, their marksmanship was extremely accurate, and the headshot rate was very high, and they quickly set fire to kill this group of roadblockers.

However, it was only a short period of delay, and the figure of the self-detonating ghost appeared behind him, and the three of them could only fight and retreat, not daring to let the self-detonating ghost catch up like this.

When they retreated to the first layer, the defense line of the three of them was already in danger, and several self-detonation ghosts were less than ten meters away from Wu Yi, who was at the rear.

"It's time!" Wu Yi raised his hand and a spring thunderbolt burst out, and the bursting bullet shrouded the ghost of self-explosion, and Zhang Qiang and the doctor also threw out a high-explosive grenade at the right time, causing a large amount of damage.

At the same time, they were subjected to such fierce resistance, and the health of several self-detonating ghosts dropped to a critical point, and they stood in place and chose to self-destruct. The flesh and blood of these self-detonating ghosts turned into the most terrifying weapons and exploded, affecting a large group of self-detonating ghosts behind them, and other self-detonating ghosts in the overlapping range of the explosion were also severely injured and chose to self-detonate.

This can be regarded as a big scene, after causing a chain reaction, there are constantly self-detonating ghosts being harmed by pond fish, Wu Yi even saw a self-detonating ghost being injured by multiple self-explosions at the same time, and before he had time to react to the self-explosion, he was blown up to pieces.

In a matter of seconds, this large group of self-detonating ghosts was completely wiped out, and the two Hulks who rushed the most quickly were killed, and a large number of souls could be absorbed by the elves, making it moan with pleasure in the consciousness exchange with Wu Yi: "What a delicious soul." ”

However, the crisis of Wu Yi and the three of them has not been resolved, and several injured Hulks have started to run wild, quickly closing the distance between them and the three of them, and when they fled to the square outside the research institute, these Hulks have been scarred, but they have also delayed the speed of the three people, and more pursuers have appeared behind them.

"Go over there!" Wu Yi pointed to the passage when he came in, and the doctor and Zhang Qiang rushed in, and he used the heavenly thunder to constantly repel the Hulk, blocking all the Hulks like a mainstay for a while.

After delaying for enough time, Wu Yi burst out with full speed, and soon caught up with the doctor and Zhang Qiang, and the three wolves rushed into the elevator.

The elevator door slowly closed, and several Hulks in a state of rage appeared in the field of vision, Wu Yigang gave Tian Leizi three bullets, and had to pull the trigger sharply to repel the Hulk that rushed to the nearest one.

The moment the elevator door closed, Wu Yi saw a huge green figure appear in the passage, and the ground was shaking with its pace.

"Boom!" After the elevator door closed, a Hulk in a violent state crashed up with huge kinetic energy, and the elevator doors made of alloy were knocked into a small piece, and the entire elevator shook violently, crumbling, and there were electric sparks flashing on the elevator buttons, if the elevator was damaged, Wu Yi could only give up the doctor and Zhang Qiang, and escaped using the wind step alone.
