The reason why Muku was lucky enough to be the first to reach a kill count of ten in a world of guns was because of three things. First, kills by guns weren't counted by whatever being that was acting behind the scenes. Second, although there were people who were more skilled than him the whole world over, they might not have had the courage to fight the beasts they faced, faced beasts that rendered their skills useless(not all of them were killer dogs after all) or didn't come across ten beasts to kill quick enough. But the main reason is, he was just lucky.
...
Muku found himself surrounded by darkness. His body felt sore all over but he couldn't open his eyes. He felt that someone or something was dragging his body somewhere but he couldn't hear any sounds.
Suddenly he felt a burning pain in his lower abdomen. He could feel a sphere forming there. And for some reason he knew what was going. It was the formation of a mana core...
[Mana core formation complete. Unusually High affinity with telekinesis and metal element detected, requirements for Legendary Specialisation met. Legendary Class, Devine Metal Warlock awakening...]
With the familiar voice saying unfamiliar things, Muku's body felt more than numbness this time. His whole body felt like it was burning all over and yet he couldn't even open his lips to scream. Making the whole experience even more unbearable. After what felt like a lifetime of suffering but was only five minutes, the burning sensation stopped.
When he was about to sigh in relief in his mind.....
[Reward Ultimate ability: Law of Nihility, generating...]
With that statement, he braced for pain, yet nothing happened. Before he could be happy he was suddenly attacked by the worst headache possible. It was so painful that he was a hair's breadth away from having his mind break. Along with the headache strange information he understood nothing of was being implanted in his mind. As soon as his the information was done being implanted, the pain stopped and he completely went unconscious.
.....
A few minutes back....
The girls was shocked to see their teacher collapse with no warning like that. All their minds went blank for a few seconds not knowing what to do.
"Shit!, someone grab his hand and lets drag him to the room. More dogs should be coming soon!." Layla was the first to regain her wits but from the suprise curse, the others knew that she was just as panicked as the rest of them. She just suppressed it because she knew they didn't have the time, which the others admired. They quickly did what she said.
And as if trying to prove her right, the remaining ten dogs on the seventh floor quickly made their way up the stairs. Drawn in by the scent of blood spreading in the air.
....
The girls had already reached the room and closed the door. Then suddenly Muku's body started twitching like crazy while sweating buckets.
"W-what's going on with him?, is he going to". Emily had already lost her cool, tears sliding down from her pretty golden eyes. Was asking no one in particular seeing Muku's state, but still hoping someone who'd tell her that he'll be fine. Before she could finish speaking though, Jade whose green eyes were also a bit puffy and red covered her mouth.
Before Emily could ask her why she covered her mouth, she heard it. The growls of the killer dogs as they fought over the five bodies of their allies. Hearing the sounds, she felt all the strength in her body disappeare and even forgot to remove Jade's hand from her mouth who had also frozen in place.
Even Layla couldn't stay calm anymore, her body shaking with fear. It seems all their courage up to that point was because they had teacher Muku with them. Then suddenly, out of everyone else's suprise, Chloe stepped forward. She held her axe tightly while facing the door, getting ready to receive any dogs that came.
Well obviously this was a dumb idea. But to the other girls, it gave them the motivation they needed. They all grabbed their axes and stood beside Chloe.
"Thanks for that Chloe". Jade said as she stood beside her.
"Huh?". Chloe was confused, not knowing what she had done.
"Nothing, lets focus on this for now". Jade said again with a smile, she couldn't help but like Chloe more after realising that she didn't even know what she had done.
Of course, Jade's weird actions only confused Chloe even more. She looked at the other two girls for some answers but even they smiled at her without saying anything.
With their attention on the door, the girls failed to notice that Muku's condition seemed to have stabilized. Even one of his fingers twitched a bit, with a faint energy being drawn into his body, his lower abdomen to be exact.
....
Close to ten minutes later...
Bang! Bang! Bang!....
It seemed the killer dogs had finally finished with their cannibalistic meal. They finally noticed the human scent close by, the poor table that was blocking their way with no back up from the humans , was soon banged out of the way.
Tap...tap...tap...tap
With the dogs so close by, even the girls with their semi awakened or even normal senses in Chloe's case, could hear them approaching.
When the multiple footsteps reached the door, they stopped. The area descended into complete silence, making the girls even more tense. Their breathing became a bit unstable and more audible.
Bang!!
As if waiting for the girls to be on edge before attacking. The door was blasted open, one dog after the other speeding into the room. Seeing this scene, the girls all had one thought....
{We're dead}
The leading dog was about to bite Chloe's head off after knocking away her axe. She didn't have enough strength to make it cut deep so it basically bounced off. The other girls didn't have enough time to react and help her because more dogs were coming and aiming at them.
Chloe seeing the giant head getting closer and closer to her, she closed her eyes. Hoping it will be as painless and quick as possible. Though deep down she knew it was definitely going to be the most painful experience of her life. And likely the last as well.
Woosh!
"Howl!!"
Suddenly she felt a slight breeze pass by her ear followed by a pained cry from a dog.
She couldn't help but open her eyes, what she saw confused her greatly. At her feet the dog was dead with a silver sword embedded deep into its skull.
"Howl!!" × 9
Before she or anyone else could react, a blurry figure passed by her and the other girls from behind. Followed by nine cries of pain from all the dogs who had made it into the room. The principal's office was large after all, especially after the removal of the giant table. And they stood a bit of distance away from the door, giving all the dogs enough room to enter.
By the time they came to their senses, all the dogs where on the floor howling in pain as their legs had been cut off. And right at the middle of them, great teacher Muku stood facing away from the girls with a bloody sword in his hand.
"Finish them off". Teacher Muku said without turning back, continuing to stand there, maybe trying to look cool. Which to the girls in that moment, he definitely did.
