After death, a soul that does not disperse but loses its intellect becomes a “Thought Soul.”
A Thought Soul absorbs energy, condenses a soul core, and ascends to become a “Ghost.”
Bytian accidentally falls into a sinkhole during the day, makes a pact with Du, a special ghost residing in a Tang sword, and transmigrates into a supernatural version of Growing Through Life that he has never seen.
To stay alive, Bytian has no choice but to go to school and practice swordsmanship by day, then hunt down Thought Souls and evil ghosts by night, collecting negative-energy particles and converting them into Netherworld particles to prolong his life.
