First Blood and the downfall of the Kalades Base

The tunnel was dimly lit and even worse guarded.....after a distance of 20 meters I hear someone's footsteps..they come my way..I silently pull out a silenced pistol and hold it ready just in case because I originally want to test out my martial arts on these poor guys..but better safe than sorry...I see a corner 15 meters before me ..I calculate that I can reach there in 15 seconds...it is to long , so I sneak a little bit closer to the corner till I was only one meters away from it.....the steps come closer...I think he will gets in 10 seconds in my reach but I'm to inexperienced to exactly say it because for this training I deactivated my domain to sharp my other senses....he arrives in my reach in 5.....4.....3...2...1...I jump around the corner while in a crouching position. I get right in front of him within half a second and punch him with full force in the stomach, this action takes his breath and prevent him from screaming.He bows front over which allows me to grip his throat an shatter it within my grip only to punch him on the side of his head which knocks him out...now he lies on the floor....completely harmless...why should I kill him? Isn't it enough already?.....AHHHhhh fuck it with this I grip his head and turn it around...I can hear and feel how his neck breaks and his life leaving his body...I really hoped that I would have hesitate more than I have done but I looks like killing isn't going to affect me much.....I pull the dead body around the corner and begin to loot him.After that I sneak further in the base......after five minutes I see a door...I stand before the door and slowly open it..behind the door is a wide open space with a little more than twenty people inside..they drink an eat while laughing together.....they put all there weapons and ammunition on a table....I take the gun from the dead member of Kalades and check the ammunition that I have...I have eight magazines ..it should be enough to destroy the ammunition of the guys down there..after that I can take them on in close combat.....I let the door open enough to take aim at the ammunition but saw something even better ....under the table I can see a box with grenades.....I now aim on the box and pull the trigger..the shot halls trough the room and I take cover next to the door which got thrown away from the explosion in the room....I wait ten seconds then I rush in with the gun on my back.....most of the people inside the room are dead and splatted across the room....the small number of people that survived thanks to the distance or there Quirks are in a confused stat of mind and didn't notice me as I rush to the one that looks like he got away the best..in this case it is a middle aged man with small scratches on his body and torn clothes..beneath the cloth I can see a metallic shine...looks like his Quirk can transform his skin in metal.....I arrive in front of him and punch him in the face because it wasn't covered in metal at the moment..the punch throws him of balance but he quickly covers himself in metal from head to toe....I begin to puch him in a fast rhythm not leting him any time to rest..my hands hurt and are damaged but I don't care...after one minute I analyzed him and found that he is weak and only has his Quirk..with that said I spin around and begin to clean the others out..some of them collected there toughs enough to react to my attacks but couldn't change much....I punched them hard an fast in the head..one after one after the other lost there consciousness till only the metal guy remains he tries to run..but did a big mistake he though I would only attack close range so he doesn't have his Quirk activated right now which I use to quickly take the gun from my back an shoot him in the head...then I walk over to a piece of a table leg and take it...with the table leg I walk over to the unconsciousness Kalades members and stab them trough the head with the table leg.
