The Gods Have Arrived: I'm Really Not Tang Sanzang

P.S. No female lead. The first few chapters are more slice-of-life, with the story picking up in Chapter 5.

Chen Yi only went out to grab breakfast, but a mentally ill man kept shouting "Master" at him and even said he would send him to the Western Paradise. Deeply moved, Chen Yi couldn't let the man's kindness go to waste, so he sent him straight to a mental hospital, where he'd have room and board.
