The county magistrate's new concubine was ill, and Eucommia ulmoides was ordered to treat her, but she died in front of the bed. His adopted daughter Du Ruo seeks the truth and clears the air of suspicion. The clues all refer to old events in Kyoto.
The old events in Kyoto are full of power and conspiracy, and shadows are emerging. What's the secret behind Eucommia ulmoides? Is it a secret in the world, or a source of disputes in the court? Is it a coincidence that the concubine got sick, or is it the result of a conspiracy?
Du Ruo explores in the fog, and is startled every step of the way. However, everyone I met kept secrets; the things I investigated seemed to be near but were actually far away. Every time I get a certificate, I fall deeper into confusion.
The secrets of Kyoto are like an arrow on a string, ready to explode. Can Du Ruo clear the clouds and see the sun in the midst of danger, solve the mystery of Eucommia ulmoides' death, and uncover the shocking secrets of Kyoto?
Intention: perseverance
