The three of them quickly arrived at the center of this area, leaning against many alloy platforms on the wall, with many zombie corpses fixed on it. The computer next to each platform records detailed data of these zombie species in detail.

From ordinary secondary biochemical ghosts to biochemical ghosts, swift ghosts, dark night ghosts, greedy ghosts, invisible ghosts, gun-holding ghosts, sniper ghosts, and red biochemical ghosts, Hulks, and Wu Yi have seen them here, and they also indicate the advantages and disadvantages and special abilities of these zombies.

Just as Wu Yi was carefully checking the shrinking zombie corpses, Zhang Qiang suddenly shouted excitedly: "Come and see what this is."

Wu Yi hurried over and saw what Zhang Qiang was referring to. This was a refrigerated storage cabinet made of special materials, with ten red potions placed side by side.

Gene enhancement agent type II: Black Iron 3. Add six points of all attributes after use. Usage requirements: Injected with gene enhancement agent type I. Note: The magic agent developed by Noren Company based on the ghost virus, so it can increase the resistance to ghost viruses after use and can be immune to infections of most elite-level biochemical ghosts.

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

Wu Yi nodded, and he immediately opened the storage cabinet, with magical potion approaching.

"Well, Brother Wu Yi, Doctor, can I get three potions? I have two friends. If they can survive... I want to strengthen the two potions for them." Zhang Qiang said embarrassedly.

"Hehe, I have three companions waiting for me to meet. I also need to get three more potions. Doctor, please take the remaining three potions. I will take advantage of this. If there is any gain in the future, I will get a little less. It's okay." Wu Yi said.

The doctor smiled and nodded and said, "I have no objection."

"Of course I have no objection." Zhang Qiang said with satisfaction.

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

With the dual-held gun skill, Wu Yi will get a great bonus for his attack power and shooting speed when holding the black and white double stars.

While the three of them were happily enjoying the pleasure of strengthening their bodies, because the three of them took the precious potion in the storage cabinet without authorization and activated the security of the intelligent system. The lights on the walls turned into strange red and flashed wildly, making people know at a glance that the situation was not right.

The alloy wall suddenly cracked, and a thick robotic arm pushed out a large row of closed cultivation tanks from it. The three of them were stunned by the amazing incident.

A large stream of gas ejected from the cultivation tank, and then the bulkhead was opened with the roar of the machine, revealing the things inside. This row of cultivation tanks was filled with alien zombies, more than a dozen hulks, red biochemical ghosts, and dozens of self-destructive ghosts. Wu Yi also saw that the center of the wall was a giant cultivation tank. Just by his body size, you can imagine that there was definitely a big guy inside.

After being exposed to fresh air, many sleeping zombies were awakened and opened their eyes one after another.

"How could there be so many mutant zombies? There are more than a dozen Hulks alone." Zhang Qiang only felt a dry throat, and cold sweat instantly covered his whole body.

"Run!" Seeing so many advanced zombies awakening, Wu Yi realized the danger. He shouted at the other two, and then ran towards the original path first.

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

"Close your eyes!" Wu Yi reacted very quickly and raised his gun to shoot. Two special bullets, one white and one black, were shot out, and a dazzling white light burst out.

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

"Kill!" In a simple word, the three of them shouted together. After using gene enhancement potion, the three of them made great progress in their marksmanship. Taking advantage of the few seconds when the ghost holding the gun was blinded, the three people with a deep sense of crisis performed at a high level. Their shooting skills were extremely accurate and their headshot rates were very high. They quickly gathered fire and killed these obstacles.

However, just after this short delay, the figure of a self-destructive ghost appeared behind him. The three of them could only fight and retreat while fighting, and did not dare to let the self-destructive ghost catch up like this.

When they retreated to the first floor, the three men's defense was already in danger, and several self-destructive ghosts were less than ten meters away from Wu Yi at the end.

"It's time!" Wu Yi raised his hand and burst out with a sudden sound of thunder. The bursting bullets enveloped the self-destructing ghost. Zhang Qiang and the doctor also threw out the high-explosion grenade at the right time, causing a large amount of damage.

At the same time, suffering such a fierce blockade, several self-destructive ghosts' health dropped to the critical point and stood there to choose to self-destruct. The flesh and blood of these self-destructive ghosts turned into the most terrifying weapons and spread out, affecting a large group of self-destructive ghosts behind them. Other self-destructive ghosts were also severely damaged within the overlapping range of the explosions and chose to self-destructive.

This was a big scene. After causing a chain reaction, the self-destructing ghosts were constantly affected by the fish. Wu Yi even saw a self-destructing ghost suffering multiple self-destructing damage at the same time. Before she could react to the self-destructing explosion, she was blown away to the point where the body was blown away.

In a few seconds, the large group of self-destructive ghosts were wiped out and killed the two Hulks who rushed the most urgently. A large number of souls could be absorbed by the elves, making it moan happily during the communication of consciousness with Wu Yi: "What a delicious soul."

However, the crisis of Wu Yi and the other three had not been resolved. Several injured Hulks started to go wild and quickly narrowed the distance with the three. When they fled to the square outside the research institute, these Hulks were already scarred, but they also delayed the speed of the three, and more pursuers appeared behind them.

"Go over there!" Wu Yi pointed to the passage when he came in. The doctor and Zhang Qiang entered one after another. He used his thunder to continuously repel the Hulk, blocking all the Hulk like a mainstay for a while.

After delaying for enough time, Wu Yi burst out with all his strength and quickly caught up with the doctor and Zhang Qiang's footsteps. The three of them rushed into the elevator in a mess.

The elevator door slowly closed, and several Hulks who were running wild appeared in sight. Wu Yigang put three bullets on Tian Leizi and had to pull the trigger to repel the Hulk who rushed to the nearest.

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