High Martial: Reborn, I Only Seek the Supreme Path

(A brainless power fantasy, so please don't think too hard while reading. The protagonist is ruthless and decisive. You can decide whether there's a female lead.) Lin Yu, an orphan, was conned into joining a shady company and eventually died from working overtime. He transmigrated into another world, into the body of someone with the same name, and finally woke up to the pursuit of supreme immortality.
