Looking for Truth Through Clumsy Writing

She just wrote the petition, but she saw through a murder case that even the government couldn't figure out. In the third year of Yongning in the Great Zhou Dynasty, there was a case of floating corpses in Linjiang River. The government arrested Mr. Accountant. The evidence is conclusive and the case is ironclad. But a girl who was writing the petition stood by the river, took a few glances, and said, "That's not right." The corpse's clothes were dry - it was not drowned. The belt is tied with a mandarin duck knot - a troupe's technique. The nails were clean—someone had washed them. Her name is Gu Zhuo. She grew up eating food from hundreds of families and made a living by writing letters for others. She didn't want to get into trouble. But the weird knot around the waist of the corpse was the one she recognized - Mandarin duck knot. The mandarin duck knot used to tie belts in the troupe. It means being in pairs and staying together until death. But why is there this on a dead person? "Sir, the lady can help you look at this case. But there is one condition." "What conditions?" "Don't ask about folk girls' past." One is a girl who writes petitions among the people. She has poisonous eyes and a calm mind, and can see things that others cannot see. One is an official of Dali Temple in the capital. He is very powerful, but he is helpless because of the case. They shouldn't have met, but they were tied together by a floating corpse. Suspicious clouds on the river bank, the missing bronze mirror, strange happenings in the old house, and unsolved cases in the capital—— Every case hides an unspeakable past. Every time she breaks the situation, she reveals the past that she doesn't want to mention.
