The King of Hell wants you to die at the third watch, but the ghost doctor will keep you until the fifth watch.
He was originally a down-and-out son-in-law whom everyone despised, but after a car accident he inherited the ghost doctor's unique skills.
Things in the world are unpredictable, but he still feels that life is worth living after all kinds of hardships. Acquiring the peerless inheritance of ghost medicine is to be able to heal the people you want to heal and save the lives you want to save.
Don't ask for a hanging pot to help the world, but ask for a clear conscience.
