Doomsday Fortress

"I've done a few experiments before, but none of them worked out too well."    

    

Professor Cheng shook his head. His gaze was focused on Zhang Fei, causing Zhang Fei to retreat.    

    

"What's the reason?" Wang Yi frowned. If the Extracted Liquid was not wrong, the capital had already been developed and applied to humans.    

    

However, there was no progress at all, which made Wang Yi anxious.    

    

After all, only by becoming stronger would one be able to protect the gathering place.    

    

"I've already used the blood you gave me from this brother of mine to study, and it's quite effective. It's just that this brother has used up all of his blood, so …" As Professor Cheng said this, he rubbed his hands, meaning that it was very obvious.    

    

"Old man, you're going to fucking draw my blood again!"    

    

Zhang Fei couldn't help but curse.    

    

"Hehe, little brother, using your blood is because you have undergone a fusion process with a Extracted Liquid. If it was someone else's blood, I might not be willing to use it," Professor Cheng said.    

    

"You!"    

    

Zhang Fei was infuriated. Last time, this perverted old man drew a tube of blood, causing Zhang Fei to be confused for a few days.    

    

"Zhang Fei."    

    

Wang Yi winked at him, wanting to develop the Extracted Liquid, this Professor Cheng was his only hope, not to mention Zhang Fei's blood, even if he wanted his own, Wang Yi would not even blink his eyes.    

    

"Alright, alright …" Zhang Fei nodded helplessly. He took two steps forward and was about to hand his arm to Professor Cheng.    

    

But right at this moment, the dog that was locked in the cage and injected with the Extracted Liquid suddenly barked crazily.    

    

"Ao! Ao! Ao!"    

    

It didn't sound like a dog barking, but instead like the howl of a wolf. Everyone's expression changed as they hastily pulled out their weapons and looked at the dog in alarm.    

    

A few of the researchers who had been in the lab also stumbled out.    

    

"There's a change, there's a change!"    

    

Professor Cheng had an insane smile on his face. He saw that the dog's body was getting bigger and bigger, and there was no hint of zombie-like madness in its expression.    

    

"Did it work?" Wang Yi muttered.    

    

"F * ck, there's no need to draw my blood this time, right?" Zhang Fei immediately retracted his arm.    

    

However, in the next moment, the mutated dog's eyes suddenly turned blood-red. Its entire body had become almost as tall as a human. With a fierce crash, it knocked out the cage that held it captive!    

    

"Damn it, I failed again!" Professor Cheng couldn't help but curse as he stepped forward to check the situation.    

    

"Be careful!"    

    

Wang Yi's expression changed, and pulled Professor Cheng back. At this time, the failed Mutant Dog's eyes flashed with a bloodthirsty look, and fiercely crashed into Professor Cheng.    

    

Bang!    

    

Cracks appeared on the glass wall in front of Professor Cheng with a dull thud. The glass wall was even stronger than bulletproof glass, so it couldn't even withstand a single strike from a Mutant Dog.    

    

"Kill it." The experiment this time was a complete failure. Leaving this Mutant Dog behind was also a disaster.    

    

"Yes sir!"    

    

Yang Ze nodded, drew his dagger and directly entered the laboratory. Everyone only saw a shadow flash past and the crazy Mutant Dog's head was directly chopped off by Yang Ze.    

    

The body fell to the ground with a thud.    

    

"How could it have failed?"    

    

Professor Cheng scratched his head in distress, while subconsciously looking at Zhang Fei.    

    

"I'm sure you gave me too little blood to study."    

    

Professor Cheng pointed at Zhang Fei and said.    

    

"Geezer, you, what the f * ck do you still want to do?" Zhang Fei was shocked and staggered back.    

    

"Blood, of course."    

    

A strange smile appeared on Professor Cheng's face. He pulled out a needle that was thicker than the last time and slowly approached Zhang Fei.    

    

In the afternoon, the helicopter took off from the Lianfeng Mountain gathering area, flying towards there.    

    

Zhang Fei laid weakly on the helicopter. His face was pale and devoid of any trace of blood.    

    

"Hehe, Bro Fei, just be content. If Professor Cheng can use your blood to develop a Extracted Liquid, then you are our benefactor."    

    

Yang Ze said to Zhang Fei while driving the helicopter.    

    

"Get lost!" Zhang Fei could not help but curse and felt unspeakably wronged in his heart.    

    

Why do you always use such thick needles when you draw blood? Zhang Fei felt that he had lightened by at least two catties.    

    

"Alright, with your level of evolution, this little bit of blood could be recovered in a day." Wang Yi said.    

    

If it really caused irreversible damage to Zhang Fei, Wang Yi probably wouldn't agree.    

    

"Where are we?" Wang Yi couldn't help but to ask when he saw a building under the helicopter.    

    

"At the edge of the Huhhot City." Yang Ze, who was driving the helicopter, said.    

    

"Bro Yi, why is there no zombie in this area?"    

    

Zhang Fei got up and looked around, but he didn't see any zombies. When he came here, it was just that no one noticed him.    

    

However, from the looks of it, this area was indeed a little strange.    

    

Although Huhhot City had a smaller number of zombies than other large cities, that was still in comparison. Even if there were fewer zombies, there shouldn't be any left in this area, right?    

    

However, the area below the helicopter didn't have a single zombie.    

    

"What's going on?"    

    

Wang Yi couldn't help but mutter to himself. It was reasonable to say that zombies were already in groups, but when the situation wasn't right, zombies were still scattered everywhere.    

    

"Roar!"    

    

Just as everyone was puzzled, a howl came from not too far away. Everyone turned their heads in a hurry and saw a few commander Mutant Zombie leading about a thousand regular zombies, quickly rushing towards this area.    

    

"Bro Yi, wh-what's going on?" Lee Weiping asked with a puzzled expression as he pointed to the group of zombies below.    

    

"Let's take a look first, Yang Ze pulled up the helicopter."    

    

Right now, the helicopter was too close to the ground, so he didn't want to attract the zombie's attention.    

    

Yang Ze nodded and controlled the helicopter to rise slowly. Only then did it stop at a height of over 100 meters.    

    

At this distance, the noise caused by the helicopter could no longer reach the ground. Wang Yi and the others could also clearly see what was happening in this area.    

    

Those zombies, why did they run here with their lives on the line?    

    

"Roar! Roar! Roar! Roar!"    

    

Following the zombies' chaotic roaring, they approached the area under the helicopter.    

    

There was a hint of panic in the howls. Even though there were two completely different species, Wang Yi could still feel it vaguely. It was as if there was something chasing after them from behind the corpses.    

    

"Bro Yi, something's wrong!"    

    

Zhang Fei, who was using his binoculars to observe his surroundings, suddenly shouted.    

    

"What did you find?" Wang Yi's expression changed and he immediately asked.    

    

"Over there, behind the corpses, something is coming!"    

    

Zhang Fei pointed at the back of the corpses and said.    

    

"Let me see."    

    

Wang Yi took the binoculars and looked at the back of the group of zombies. He saw that in the middle of the low building, there were shadows of zombies in a fan-shaped formation, surrounding and chasing away thousands of zombies.    

    

"That's …" Wang Yi adjusted the focus of the binoculars and carefully observed the creatures that were driving away the zombies.    

    

"It's them!"    

    

Wang Yi couldn't help but exclaim.    

    

"Who?" "Is it a zombie?" Lee Weiping asked.    

    

"No, you still remember, that time after we captured the Grand Green Mountain, those two thousand deserters were killed." Wang Yi said.    

    

"Remember Bro Yi, didn't you say that Professor Cheng's failed experiments were done by him?" Zhang Fei said.    

    

Those failed experiments were actually humans, but it could be said that they were a species between humans and zombies. Wang Yi wasn't sure what they actually belonged to.    

    

"Those monsters are the ones driving the corpses away." Wang Yi said in a deep voice.    

    

"Drive the zombies away?" Are they humans!? "    

    

Lee Weiping couldn't help but open his eyes wide as he looked down. The zombies were like sheep that were being raised by the herdsmen. They were driven one by one by the monsters and arrived at the designated location.    

    

"No, definitely not human."    

    

Wang Yi shook his head decisively. He thought back to the two monsters he had encountered before. According to their performance, they definitely had nothing to do with humans.    

    

According to Professor Cheng, he had conducted more than 200 experiments, and there were also more than 200 failed experiments.    

    

Looking at the monsters that drove the zombies, there weren't many of them, only close to a hundred.    

    

"Where's the rest?" Wang Yi was confused and looked around.    

    

At this moment, the herded corpses had almost arrived at the place underneath the helicopter. Hundreds of figures suddenly drilled out from the buildings in front of them, scattering in all directions and surrounding the dead bodies!    

    

"They're all here!"    

    

Wang Yi exclaimed in a low voice. More than two hundred failed experiments had all appeared in front of everyone.    

    

"What are they doing?" "Hunting?"    

    

Zhang Fei couldn't help but mutter under his breath. From the way these failed experiments were conducted, it seemed as if they were hunting zombies. The zombies were completely surrounded.    

    

No one said another word as they watched the situation unfold with heavy expressions.    

    

An unknown creature actually drove all the corpses together for a hunt. It was enough to make everyone sigh in amazement.    

    

As the failed experiments surrounded the group of corpses, the slaughter arrived on time.    

    

"Roar! Roar! Roar! Roar!"    

    

The zombies were killed one by one by the agile and aggressive monsters.    

    

It was as if these strong zombies were like paper in front of them, weak and fragile. Even Strong Corpse s could not fight against these monsters.    

    

"Alright!"    

    

"Beautiful kill!"    

    

"Kill these bastards!"    

    

Seeing the zombies that were killed by the monsters, the helicopter began to let out a few cheers.
