An Undocumented Cultivator? Even a Sliver of My Soul Must Live Well

[The journey of a fragment of a soul as it struggles to survive, establish itself, and explore the cultivation world] There are battles as well as peaceful days, warmth as well as danger. No female lead. The protagonist has Nascent Soul-level combat strength from the start. He’s good at fighting and decisive in killing, with a normal personality and a bit of a cheeky streak. He’s genuine and true to himself.

The protagonist was an unlucky modern-day man who was reduced to a remnant soul and couldn’t be reincarnated. A kind underworld customer-service agent sent him to the cultivation world as a soul fragment of a powerful cultivator, where he spent 120 carefree years lazing about. But then the cultivator unexpectedly died. How can he, as a soul fragment, protect himself and continue roaming the cultivation world?

(The male lead has many friends, but no romantic pairing of his own.)
