Song Ci, a widower and apprentice in Kaifeng Prefecture, found half an official seal during the autopsy at Daxiangguo Temple. This double tiger talisman belonged to Li Chongxun, the privy envoy who was executed twenty years ago. What's even more bizarre is that the other half of the official seal is embedded in a secret room in Song Ci's father's study. That night, my father died suddenly. Before he died, he wrote in his blood on the "Resolution of Wrongs": "Don't trust the prime minister." When Song Ci found the same gold foil as the Prime Minister's Mansion in his father's throat, the footsteps of pursuers sounded outside the door.
