Delivery boy Chen Jin received an order from a fire scene on a rainy night and picked up a black stone that was inscribed with the history of human despair. When he discovered that negative emotions could turn into blazing flames, he was dubbed a "serial arsonist."
On the way to escape, the paralyzed old man used his last fire to guide him, the suicidal girl sang happy birthday in the ashes, and the policewoman who was chasing him had a human bone lighter on her waist.
It wasn't until Chen Jin ignited himself and rushed into the core of the eternal night that he discovered that all the dreams that died, the engagements that were canceled, and the souls that were dried up in 996 were the nourishment for higher civilizations to select "cremators".
