I'm a Low-Key Killer

Killer is a special and low-key service industry. In a plane crash, a top killer was blasted to ancient times by thunder and was reborn. He gained tremendous power as the thunder and lightning washed his marrow and cut his bones. Although he insists on adhering to the low-key professional ethics of a killer, in the face of various provocations, should he continue to keep a low profile and protect his ethics, or should he rebelliously go up front and trample or even obliterate his enemies in a high profile? Life is composed of countless choices. What is his choice?
