There is a group of people who seal one fragment of their soul into a life ledger, their spirits never dispersing. They ferry ghosts across, heal troubled hearts, and speak not of right and wrong, but of cause and effect.
As the saying goes: “A lifetime spent crossing the road between yin and yang; half a step from right and wrong, grudges and gratitude fading at dusk.”
And after I inherited the ancient contract from my grandfather, I named it the Ghost Doctor Sect!
