Review Detail of Downery in My Fusion System: Fusing a Thousand Chickens at the Start

Story has decent op system that could be fun to read about but the author has less then 2 brain cells. Has crazy op skill he intends to keep secret, even from family. Couple chapters later shows it off in front of people trying to rob and kill him. Doesn't kill them let's them go. Now here's the major point, he didn't have to show it off, he could've used it waaaaaaaaaay before showing his face but decided the best time to use it was in front enemies that wanted to rob him and kill before letting them all go free. Cue next incident. This time he actually kills the leader but let's everyone else live but again shows off this super secret skill that could bring disaster to him and family to people he doesn't intend to kill. Fool won't tell his family openly but shows it enemies he doesn't intend to kill.
