After killing all the patrolling soldiers, everyone gathered at the entrance of the institute. The hound quickly pried open the door of the research institute, Zhang Dong led everyone to rush in at once, and two passing scientific researchers were put away by Zhang Dong one by one.

Zhang Dong stretched out three fingers, then made a scattered gesture, everyone nodded, and quickly walked towards the different passages in groups of three.

The hound and Xiaoya followed Zhang Dongchao into the elevator and quickly descended to the first floor, which was where Rankel was. Zhang Dong has been to this institute twice, both of which are escorted to the battle uniform to do experiments, so he is quite familiar.

At this time, there was the sound of gunfire from upstairs, and it seemed that a small group had exchanged fire with the enemy, "Speed up!" Zhang Dong ordered, speeding up the pace of advance.

Soon, the alarm sounded, and a door next to Zhang Dong suddenly opened, and five or six soldiers rushed out from inside, but before they could react, they were killed by three people, and they didn't fire a single shot from beginning to end.

Soon Zhang Dong and the others came to a place like a prison, which was full of people, some people were conscious, shouting for Zhang Dong to save them, and some people were already dead, their eyes were empty, and they didn't even breathe.

At this time, a voice sounded on the radio of the institute: "I am Rankel, the institute has been invaded and will enter defensive mode, all scientific researchers, please stay in the laboratory and do not come out." ”

As soon as the words fell, several prison gates opened, and those "people" with empty eyes walked out, and when they saw Zhang Dong, they frantically pounced.

"Fire!" Zhang Dong immediately ordered.

The three of them all had good marksmanship, almost all of them were headshots, but even if their heads were blown out, the bodies of those people still rushed towards Zhang Dong and the others. "Get out of the way!" Zhang Dong saw that the gun didn't work, so he immediately took out the Heavenly Dao Divine Sword and greeted these "people".

After a period of sword shadows, all the "people" were cut into several pieces by Zhang Dong, and they could no longer pose a threat.

"Keep going. After speaking, Zhang Dong led the three of them and continued to walk towards the laboratory.

"Whew!" just as the three of them were approaching the lab, a wolf howl suddenly rang out.

"Woohoo!" "Woohoo!" With the first wolf howl, followed by another howl, several pairs of eyes lit up in the darkness.

Zhang Dong already had in his heart that these were werewolves like Guo Chen, but he didn't expect there to be so many. "Be careful, this is a werewolf, *bullet!" After speaking, Zhang Dong took out a *, pulled off the pull ring, and threw it over.

Xiaoya and the Hound also followed suit and threw two pieces*. Three* exploded in the midst of the wolves in an instant, and several werewolves were directly blown to pieces. "Fire!" The explosion of the * bomb also angered the remaining werewolves, and they quickly pounced on Zhang Dong and the others.

Fortunately, the rifle is more powerful than the pistol, and it can still cause some damage to the werewolves, at least there is no problem in stopping them from advancing.

The werewolf was injured and wailed in pain, Zhang Dong took out a bazooka and killed all the werewolves with one shot.

After confirming that there was no danger, Zhang Dong and the others continued to move forward, and at this time, Xiaoya suddenly called: "Captain, there is an unknown lifeform approaching outside!"

Zhang Dong took the meter in her hand and found that there was indeed something approaching, and it seemed to be very powerful.

"Roar!" At this time, that thing also appeared in the field of vision of Zhang Dong and others, this TM is completely a monster, more than two meters tall, and the parts on its body are all made of different parts of different people, just like Frankenstein in the movie.

The Frankenstein, armed with a giant axe, slammed it at the trio. The trio quickly dodged and then opened fire at the same time. The bullet went deep into the monster's body, but it couldn't penetrate it, and it didn't even affect him.

"MD!" Seeing that the bullet had no effect, Zhang Dong took out a bazooka and blew it up with a single shot, and immediately blood and flesh flew everywhere. Frankenstein had a huge crater blown up in his chest, but as if he didn't feel pain, he continued to swing his axe and slash at the trio.

Zhang Dong's face turned cold, and the Heavenly Dao Divine Sword was held in his hand, and he fought with Frankenstein. Although Frankenstein has a lot of strength, he moves very slowly, and soon his body was cut by Zhang Dong more than ten times, and one hand was also cut off by Zhang Dong.

Zhang Dong jumped up from the wall next to him and cut off his head with a sword, and Frankenstein fell to the ground.

"What the hell have these people studied? These monsters are terrifying. Xiaoya wiped the sweat from her forehead and said.

"Let's go! There's Rankel's lab ahead, be careful, maybe there's something even scarier there. Saying that, Zhang Dong installed a * on the wall.

The three of them quickly came to the door of the laboratory, smashed the lock with their guns, and kicked the door open. There was a person on the sofa in the laboratory, but it was not Rankel, his eyes were hollow, and when he saw Zhang Dong and others, his eyes instantly turned blood-red!

"Ahh

However, this werewolf was stronger than the ones Zhang Dong had encountered, and his fur was red. "Woo!" the werewolf screamed and pounced.

The three of them shot quickly, but this time the bullet had no effect on the werewolf at all, and it hit the werewolf as if it were hitting a steel plate, splashing sparks.

The three of them rolled to the side and dodged the werewolf's attack, and the werewolf ignored the hound and Xiaoya, and rushed towards Zhang Dong. Zhang Dong's eyes flashed, and a bazooka appeared in his hand. "Boom!"* exploded on the werewolf.

The werewolf got up from the ground and shook his head,* which did not hurt him in the slightest, but only burned his hair to the black. Zhang Dong's pupils shrank, what the hell is this TM, cannonballs can't be killed, and the defense is more terrifying than the master of the gods?

The werewolf pounced again, and was kicked away by Zhang Dong, smashing the wall, and the wall was smashed into a big hole. Zhang Dong felt as if he had kicked a large piece of iron just now.

The werewolf didn't have any problems, he was scared again, and opened his bloody mouth to bite Zhang Dong. Zhang Dong got to the ground, his feet against his paws, and grabbed his mouth with both hands, "Hound, *, throw it into his mouth!"

At this time, the werewolf's mouth was forcibly moved away by Zhang Dong, and the hound hesitated for a while, but still gritted his teeth and threw * into the werewolf's mouth.

I only heard a muffled sound, as if * was thrown into a jar, the werewolf's body was not damaged at all, but smoke came out of his mouth, a mouthful of blood sprayed on Zhang Dong's face, and his strength gradually decreased.

Zhang Dong let go of the werewolf and got up from the ground. The werewolf twitched a few times on the ground and died with his head tilted.
