Assassin training

My name is Scott Black I was taken into the black family when I was 8 they were a rich and powerful family of assassins as soon as I was taken in they started my training at first it was pain training they electrocuted me broke bones anything as long as it wouldn't leave permanent marks once I was used to that they gave me a serum that healed any skin they cut or burned so there was no scars then continued my training with wiping cutting punching burning etc they had taken other kids before me the youngest was 15 and the oldest was 19 but they broke and killed them selves so they decided to try and get someone younger so they picked me they found me on the streets

When I turned 10 they had already taught me fighting techniques acting politics first aid weapons information gathering how to torture parkour lock pick and hundreds of languages sneaking killing escaping and lots more I also learned dancing instruments strategy coding hunting animal tracking hacking and more for fun in my free time when I turned 13 I was already the best assassins in the family so they decided to adopt me officially most people in my position would probably hate my family for the pain and training but not me I loved my family more than anything so when they we're all killed on my 20th birthday I took revenge I found out it was revenge for a billionaires son who we assassinated for being a rapist and throwing money around to make it disappear so before I left I gave the families money to charities it is around 100 billion I knew I wouldn't come out of this alive
