Humans and ghosts have different paths. In order to draw a clear line between life and death and suppress and conquer the undead spirits that disturb the human world, the King of Hell opened a special school for ghost officials to study, called: Underworld cram school. Choose a soul with a certain soul weight from a group of ghosts and train them to become outstanding ghost officials.
Ghost officials can freely enter the human world and the underworld. After Lin Yi died, his soul drifted to the underworld. He drank the soul-breaking soup handed over by Meng Po and participated in a game called Hundred Ghost Gu. The winner was the official and the loser died.
It's so easy to be a ghost official. To stand out from the crowd of ghosts, you must first endure the loss of arms and legs, in case your body is eaten by other ghosts.
The so-called soul weight reaches the standard. Lin Yi knew from the moment he joined the game that he had to swallow ghosts and use other people's souls to add to his body. In order to survive, Lin Yi bit ghosts when he saw them...
Between life and death, the memories of the past life came back. The ghosts of the two lives entered the ghost world. In the previous life, they proved the truth for the master and fought against the 'God Realm' with their own bodies. They ended up in a state of despair. I thought I could be an ordinary kid after reincarnation, but I didn't know that the involvement with the previous life continues to this day~
