Daqian's soul died. The loser prince Lu Chen was demoted to guard the Scripture Pavilion due to his mediocre talent. He became an abandoned son guarding the old files. The powerful people silenced him and his brothers betrayed him. In a desperate situation, he awakened the file deduction system and was bound to the forbidden palace attic. Anyone who entered the cabinet with hostility would have their cultivation level reduced by 90%. He devoured blood and essence to break through. He overturned a century-old unsolved case while talking and laughing, and controlled the life of the court. Only when his former enemy stepped into the territory did he realize that this loser had already become the god who judges all living beings.
