My System & My Academy of Superpowers

The zombies approached Ryan with furious expressions and aggressive movements. 

"Come! I am ready!" Ryan shouted.

In response to Ryan's sound, the zombie in front galloped towards him, mouth wide open. Ryan gritted his teeth and began running towards them. 

Ryan raised his fist and landed a hard punch in the zombie's face. Blood spilled all over Ryan's face and clothes. He threw the zombie away and turned around.

He ran away from the zombies. "Boil!" the blood of the first zombie started boiling. In just a few seconds, it was boiling at a high temperature. 

Of course, the zombie's body was already destroyed from the inside out. A smile appeared on Ryan's face when the zombies behind hesitated a little.

"Let's go!" He charged forward again. 

< Revenger zombie kills: 1/29 >

Cracked open a zombie's jaw and used the skill right away. Ran inside between the group of zombies. In five seconds, Ryan punched five zombies.

"Boil!" Ryan commanded after getting out of the ground with a few zombies behind him.

The zombies he punched were the ones who were standing in the center of the group, when their bodies blasted away it took two more zombies with them. 

'It's working.' Ryan grinned, 'I wish I had a weapon though.' After his hunk mode was deactivated, his demonic katana also disappeared. 

Ryan elbowed a few zombies behind him, threw them away, he constantly felt a stinging pain in his whole body. 

'Damn, this will never end.' When he was killing the first 80 zombies, it was a new experience for him. He was enjoying killing them, he was angry at Ainz and wanted revenge. 

He didn't focus too much on killing the zombies; all he wanted was Ainz's head. But now that he was asked to kill the remaining 29 zombies… it was troublesome.

He had gotten used to the zombies quite a lot. They were not able to kill Ryan but Ryan was easily able to kill them.

< Zombie bites: 40/5 >

Yeah, thanks to his System. If it was not for his System, Ryan would have been turned into a zombie 40 times by now. Zombie bites were not infecting Ryan at all.

'A massacre. That is the only way I could end this quickly.' Ryan thought. But there was no way he could make a massacre happen here.

He doesn't have any manpower like Jackie or Tye. he doesn't have any guns either. No guns, no men, nothing. A blast could be enough to take the zombies down but…. Nothing to make a blast either.

"This is getting troublesome," Ryan muttered as he punched another zombie.

< Total Revenger zombies kill: 15/29 >

'Argh! 14 more!' he quickly calculated the remaining zombies, 'Still man, I can't believe I am doing this. I mean…. I never thought I would be smashing zombies' heads one day in my own Academy. This is sick.' 

Although it was an evolved world, a world where everybody had their own superpowers which would happen in movies, anime, drama, fantasy stories, etc was happening for real here, Ryan never thought mythical creatures would become a reality too.

Devon made it pretty clear that mythical creatures were the first ones to exist on the planet, even before the humans with superpowers came into existence. 

Ryan gained a mysterious Ring which turned out to be an RPG System. He soon meets vampires. To his surprise, things just don't end there.

All of the students in his dormitory turn into zombies overnight. An in-Academy zombie apocalypse broke out. At last, he meets werewolves too. 

And now here he is, smashing the brains and boiling the blood of numerous zombies. Why? Just to gain Exp and level up quickly to grow strong. 

"Ouch," Another zombie lept itself forward and grabbed a bite of Ryan's shoulder, "Pete?" He turned around to find someone who was not Pete. 

In disappointment, Ryan grabbed the zombie by its neck, swung it around, smashed the zombie on the wall.

"Die," Ryan muttered while squeezing the zombie's neck. Blood started pouring out of the zombie's neck, "Boil!"

< Blood Storage: 0/150 >

'Huh?' Ryan let go of the zombie, the zombie landed on the ground sliding against the wall. The hot blood boiled the zombie's brain from inside. 

"What is the meaning of this?" Ryan used his skill recklessly to end the zombies but he forgot one thing…. His Ring wants blood.

"Fuck, are you serious?" Ryan was out of his blood store. All left with him were his blood level and HP. 

'How can I be so dumb?!' Ryan grabbed another zombie by its neck and threw it on the ground. Its head blasted in million pieces with its hot blood.

'How can I forget the simple basics?!' Ryan cracked another zombie's head. Its brain popped out, Ryan smashed the brain with his leg.

"This Ring. It wants blood!" Ryan furiously started hitting zombies around him. Without the little consciousness of what he was doing, Ryan just kept hitting whoever came in the diameter of his attacks.

'The stronger the skill is the more blood the Ring will need. I totally forgot it.' Ryan regretted using his skill so recklessly. 

Ryan continued using his skill: blood fist continuously without stopping. Hitting every zombie with the diameter of his attacks.

Ryan didn't stop until he received this message from the System"

< Revenger zombie kills: 28/29. Kill the last zombie to gain random rewards >

"28? Only one remaining?" Ryan came to his senses. He was panting hard, gasping for breath. 

Ryan lifted his head to look around. It was a total mess. Blood, brain, parts of body, limbs, fingers, eyeballs everywhere. 

"What have I done?" Fear spread over Ryan's face when he realized he might have made a mistake.

Ryan kicked every dead body looking for Pete's body, 'I didn't kill him, did I?' Ryan kept looking all over the floor, going through every corpse. 

"It's not here…." After Ryan didn't spot Pete's body, he figured out what must be the case, "Only one zombie is left to kill, Pete's body is not here… which means. The last remaining zombie is Pete!"

He was somehow relieved that Pete was not killed by him… yet.
