The second year after Wu Zetian ascended the throne was a time of great turmoil. Luoyang City, known as the "City of Gods", is bustling and picturesque, day and night. However, behind this magnificent city, there is an unsolved darkness.
Late one night, a scream came from an imposing mansion in the south of the divine capital city, piercing the calm night sky. The owner of the mansion, Shen Xu, the Minister of Rites, was found dead in the study early the next morning. The death state was horrifying, his eyes were wide open, a short sword was stuck in his chest, and the desk was soaked with blood. There is also a blood book left on the desk, which reads: "Blood debts must be paid with blood."
Wu Zetian was furious after hearing the news and ordered the minister of Dali Temple to quickly investigate the case. However, several days passed without any progress in the case. Rumors spread, some said it was a ghost seeking life, others speculated it was a power struggle. Just when Dali Temple was in dire straits, the Queen personally issued an order and ordered the world-famous Di Renjie to supervise the case.
When Di Renjie received the order, he was sitting alone in his study, writing and fidgeting with the sandalwood in the incense burner. The green smoke curled up, as if there was a hint of mystery. He raised his head, cupped his hands to the eunuch who delivered the order and said, "I will live up to the Queen's trust."
