This book could also be called The Little White Wanderer's Diary
Kicking the celestial palace in the Ninth Heaven, beating up the phoenix, the last god alive in the world wanders from place to place, patching things up as he goes. He travels across the Four Great Continents, drinks every last drop of fine wine, draws his blade to help those in need, and wins the hearts of one NPC after another.
The protagonist shines on his own, with no male lead.
The author's imagination isn't huge, and the writing goes wherever it pleases. The text may be revised later. Just enjoy the read.
