At the age of twenty, life came to an abrupt end. Lin Xiaxi never thought that a seemingly accidental drowning would be the end of his life.
Turning into a wandering spirit, he stood in front of his dilapidated new grave, watching the false grief of his uncle and aunt, the only remaining relatives in the world, and listening to the intriguing hidden story behind "compensation". His parents disappeared when he was seven years old, and he was left to live under the shelter of others and suffered a lot. Now he died in an unknown manner. The overwhelming injustice and unwillingness made it impossible for him to go to the underworld safely.
However, what Lin Xiaxi didn't know was that what happened to him was no accident. Behind him, the mysterious "Yin Patroller" from the non-human world is quietly watching, evaluating his obsession and potential. The secret origin of his Lin family ancestors and the extraordinary resilience of his soul fire have made him a "special observation object" in the eyes of certain beings.
From the ignorance of the wronged soul to the insight into yin and yang, Lin Xiaxi's life in the underworld is doomed to be thorny and secret at every step. Not only does he want to find out the truth about his wasted death and pursue the mystery of his parents' disappearance, but he also wants to earn his place in this unpredictable netherworld.
