Records of Strange Things in Tiandu

My name is Xu Xiao, a policeman who died accidentally during a mission. At this time, my soul and body came to the Tang Dynasty world and became Xiao Zhenbang, Di Renjie's first disciple. One day, His Majesty secretly summoned me. Because the Tiandu Chao Gang was in chaos and the enemy troops were watching eagerly. Your Majesty was young and the Princess of Tiandu had limited abilities, he asked me to go to Tiandu to solve strange ghost cases, stabilize the court situation and restore peace to the world.
