Serial killer in the cultivation world

John was a 25 year old man before he died.
How or why is not relevent.
The truely important part is that he reincarnated in a cultivation world.
He was gifted, or cursed, with a system.
If who you are is randomized in our world, he was able to chose who he would be in his next.
The thing is, he had to be a killer.
His life, from there on, became lies.
Forced to kill and bound by the chains he put on himself, his life became a slasher.
The system rewarded killing and fear, but he paid it no mind
For he had long became a killing machine.
