Doomsday Fortress

Lee Hu couldn't help but shiver, mainly because he really didn't feel safe in this situation. His hands and feet were fixed, and beside him stood an old man with a weird smile on his face.    

"Don't worry, this is made of the special steel used to make rifles. No matter how strong you are, don't even think about getting away."    

Professor Cheng revealed a smile that would make anyone who saw it tremble with fear. He then opened the alloyed box on the side and took out the Extracted Liquid and the syringe.    

Lee Hu struggled hard when he heard that. The two handcuffs were unusually strong and did not show any signs of breaking.    

"Bro Yi, will anything happen to Brother Hu?" Yang Ze, who was on the side, couldn't bear to look and whispered.    

"He has Fourth Level Evolutionist. Theoretically, he would not be infected by the zombie virus, but …"    

Wang Yi hesitated. Honestly speaking, Wang Yi had some doubts about Professor Cheng's Extracted Liquid.    

"Pu ci!"    

Before he could finish, Professor Cheng had already inserted the needle into Lee Hu's arm. Immediately after, he injected all the Extracted Liquid in the needle into the arm.    

"No …." "Nothing much …"    

Lee Hu only felt a wave of pain, but his body didn't have any reaction after that.    

"Don't be anxious, the Extracted Liquid will take some time to fuse with your body." Professor Cheng said.    

"Geezer, I'm afraid this game of yours is not ineffective …" "Ugh!"    

Lee Hu's voice suddenly paused, then his eyes suddenly widened as his eyeballs became bloodshot.    

"Ah    

Lee Hu couldn't help but howl. His entire body seemed to have been struck by lightning as it trembled. The blood vessels on his arms burst out and he could feel that the blood in them was flowing faster.    

"Professor Cheng, Lee Hu, he …"    

Wang Yi couldn't help but ask.    

"Relax, this is a normal phenomenon. When Extracted Liquid is injected into the body, it needs to be fused with the blood in the body to improve the body's constitution. It is normal for there to be some slight pain." Professor Cheng said lightly.    

"Are you sure this is a minor pain?"    

Yang Ze couldn't help but raise his eyebrows and point at Lee Hu, who had a hideous face on the bed and was hanging up in the air with both of his hands shaped like eagle claws.    

Everyone could feel that Lee Hu was in extreme pain.    

"Cough, cough …" This pain depends on your physique. The more intense your performance is, the better the effects of the Extracted Liquid. " Professor Cheng coughed awkwardly and quickly explained.    

"F * ck, if anything happens to him, laozi will be the first to kill you." Yang Ze cursed angrily. Of course, these were just angry words.    

Finally, after about 10 minutes, Lee Hu's body stopped struggling. He fell onto the bed as if he had no more strength left.    

"How is it?" Wang Yi hurried forward and looked at the pale Lee Hu.    

Luckily, even though Lee Hu looked weak, there weren't any changes. He was still a human, not a zombie or any other species.    

"I... "I'm fine …" Lee Hu shook his head. Although the pain was sudden and intense, it was only pain. Lee Hu didn't feel anything else.    

"Brat, you are the first person in our gathering area that has gone through the transformation of a Extracted Liquid." Professor Cheng came forward and said with a smile.    

Although Zhang Fei had also used Extracted Liquid before, it wasn't something that was produced with a concentration of Lianfeng Mountain.    

"F * ck, geezer, since you're in so much pain, why don't you tell laozi that you did it on purpose?"    

Looking at Professor Cheng's face that looked like he deserved a beating, Lee Hu could not help but curse. He suddenly raised his arm and grabbed Professor Cheng's collar.    

Ka-cha! *    

A crisp sound surprised everyone.    

The handcuffs made of the special alloy were torn apart by Lee Hu.    

Lee Hu was also stunned. He let go of Professor Cheng's collar and stared blankly at his hands.    

"How is it? Do you feel that the power in your body has increased by a lot? "    

Professor Cheng tidied up his clothes and said.    

Lee Hu hesitated for a moment before he exerted force with his other hand. Crack! The other handcuffs were also broken.    

"That's right, although he's still in the Fourth Level Evolutionist, but in terms of strength, he's already close to becoming a level 5 evolved human." Wang Yi nodded and said.    

Wang Yi was the only one with the right to speak. After all, Wang Yi was a level 5 evolved person, so he was familiar with the power of a level 5 evolved person.    

Lee Hu had just broken through the Fourth Level Evolutionist a few days ago, so it was very normal for his strength to crash into the Fourth Level Evolutionist. But now that he used the Extracted Liquid, he was actually infinitely close to becoming a level five evolved person.    

"Lee Hu, come down quickly, I want to try the Extracted Liquid too."    

Yang Ze said with his eyes beaming.    

To be able to raise his strength, who wouldn't want to?    

It was Yang Ze's turn to lie on the sickbed. After Professor Cheng changed the syringe, he injected the Extracted Liquid into Yang Ze's body.    

However, Yang Ze's reaction was not as intense as Lee Hu's. It was just that there was a slight pain, but no other feeling.    

Even when Yang Ze got out of bed, he still looked confused.    

"Are there any improvements?" Wang Yi asked.    

"Bro Yi, I-I feel like my speed is a bit faster, but it doesn't feel like much."    

As Yang Ze said this, he waved his fist hard, causing a series of whistling sounds.    

"What's going on? Why is Lee Hu's improvement so big, but there's no obvious change in Yang Ze? "    

Wang Yi frowned and said.    

"He's a fourth-level Adept, and Lee Hu is an ordinary evolved person. The two are not on the same level in the first place, and the Extracted Liquid's effect is that great, it's the same for everyone. Lee Hu could feel the obvious increase in strength, and it was also because he was not as strong as Yang Ze, that caused the two to have different results." Professor Cheng said.    

"What you mean is, if you replace him with someone weaker, the improvement will be even more obvious?" Wang Yi said.    

"Right... Professor Cheng nodded. Although he was a bit crazy, he was still very professional.    

"Alright, let's change to a lower level one …" Wang Yi waved behind him, and a Second Level Evolutionist soldier immediately walked over.    

Since he had already done the previous two experiments, it proved that the Extracted Liquid was absolutely safe, so there was nothing to worry about. The soldier just laid on the bed, and after being fixed up, Professor Cheng injected the Extracted Liquid into his body.    

"Ah ah ah ah ah!    

Once the Extracted Liquid was injected in, the soldier immediately cried out in pain.    

"Bro Yi, this kid's reaction is much better than Lee Hu."    

Yang Ze said while rubbing his chin. With such a huge reaction, after he fused with the Extracted Liquid, he might even be able to become a Level 3 Adept.    

A whole level higher could be said to be fast.    

"That's not right." However, Wang Yi shook his head. No matter how effective the Extracted Liquid was, it shouldn't have cried out so miserably, right?    

When he looked at his body again, his skin was bulging, as if there was something underneath that was about to come out.    

At this moment, the soldier's arms suddenly exerted force, and he broke free from the two handcuffs.    

"Quick, retreat!"    

Wang Yi growled and immediately pulled Professor Cheng back. In this laboratory, Professor Cheng was the weakest, so naturally, Wang Yi's first protector was him.    

However, after the soldier struggled down from the bed, he didn't rush to attack anyone, but stood on the spot, his eyes suddenly glowed with a red light, at the same time, two sharp fangs appeared from his mouth, his skin also started to change in an instant, the muscles on his body suddenly expanded and split, his pair of sharp claws were like steel blades.    

"What the f * ck!"    

"Old Man Cheng, what kind of monster are you f * cking creating?!"    

Lee Hu couldn't help but exclaim in surprise. He almost had a heart attack from the scene before him.    

A good soldier changes his mind, and he isn't a zombie of any kind.    

It was as if an ordinary zombie had been strengthened.    

"Kill it!"    

Although he was previously a soldier, now that he had become a zombie, Wang Yi definitely couldn't let him go out alive.    

"Yes sir!"    

Lee Hu let out a low growl. He hadn't used his newly upgraded physique yet, so he wanted to use this zombie to see how much he had improved.    

Roar!    

After this soldier transformed into a zombie, he didn't have any hesitation. The bloodlust in his heart was triggered, and with a whistling sound, he charged into the crowd.    

Bang!    

Lee Hu stood up and kicked the zombie's chest.    

One person and one corpse retreated, but the zombie hit the iron bed behind it. With a "kang" sound, the bed was twisted, and Lee Hu was able to stabilize his body after taking two steps back.    

Wang Yi was surprised at the side. Although Lee Hu had Fourth Level Evolutionist, his strength and speed had both increased after the improvement from the Extracted Liquid, and he was nearing level 5 evolved person.    

Even the most powerful Mutant Zombie in the group of zombies, its claws, might not be Lee Hu's match. However, this zombie was able to withstand Lee Hu's kick without much damage.    

It could be seen that this zombie that was transformed by the Extracted Liquid, although its appearance was similar to normal zombies, its strength was probably lower than the current Mutant Zombie!    

"Geezer, take a look at what you just did."    

Yang Ze couldn't help but ask.    

"I-I don't know what's going on either."    

Professor Cheng was on the verge of tears. He had finally succeeded twice and failed the third time, and the most important thing was that these Extracted Liquid were all produced in the same batch. If there was a problem with it, then there should be a problem with it.    

"Roar!"    

After being kicked back, the zombie's bloodshot eyes stared closely at it. It roared and once again charged forward.    

"Damn, you f * cking know how to fight."    

Lee Hu cursed. This zombie was probably the strongest zombie that Lee Hu had ever encountered.
