Su Xiao is a hunter who crosses countless worlds and is reborn through one quest after another, bound by a blood-soaked pact struck on a night of beheadings. His ruthless blade cuts across the seven paradises, leaving heads scattered behind him, until his name turns into a symbol of terror. Killing has become routine and life or death barely registers, yet the death of his parents stays with him. A gray gentleman smiling darkly under his hat, strange totems rising out of corpses, and the crushing power of an ancient god in the dark slowly expose what really happened that year. Hunting down the true culprit, taking up the legacy of the law's extermination, and bringing the elements back into balance become the fate he cannot escape. The action fantasy pairs a grim, violent hunter with a mystery rooted in his past.
