After some exchange, Duan Mingyuan had figured out the situation of the Mechanical Star's Royal Court.
The Chancellor had been bought by the Shanqi Commerce Association years ago, with the purpose of uncovering the secrets of the Mechanical Star's treasure. Yet, although the empress trusted him, she never disclosed the treasure's secrets to anyone.
The scepter, forged by the first great craftsman, possessed secrets only known to the successive heirs to the throne.
The Chancellor conspired with the doctor, plotting to seduce the ailing empress into a "Soul Swap" ritual to search her memories.
The doctor was an agent of the Chamber of Commerce, and the equipment was also provided by them.
