[System + Transmigration + Ancient Political Intrigue + Equally Matched Leads]
Other people coast through quick transmigration. I work a 996 schedule, serving emperors to keep myself alive.
With a diagnosis of ALS and only three months left to live, I bind myself to the Emperor-Raising System.
The System's rules are simple: transmigrate through ten ancient worlds and help someone become emperor. Clear one world, and I get one more day to live.
I think it's a technical job: use intelligence analysis to help a prince from the Cold Palace seize the throne, veterinary skills to help a prairie wolf cub win the position of khan, and letters hidden in ginkgo leaves to conspire with a puppet emperor in a coup.
Wait, am I here to work, or to embark on an epic romance spanning ten different eras?
