My Whole Family Was Exiled, but the Peerless Female Emperor Recruited Me as Her Imperial Preceptor

I woke up one morning to find myself the eldest son of a Vice Minister of Revenue. A political rival had framed my family, and we were all about to be exiled. The male lead had been scared to death, while I, a modern doctoral student who had dropped dead at the office from staying up late every night, had arrived in this era in the body of that spoiled young master.

From the start, my family was being confiscated. Why was I so unlucky? Other people transmigrate and get a golden finger. Why couldn't I transmigrate into an emperor? A prince? A crown prince? At worst, a young imperial grandson. Good heavens, what kind of joke are you playing on me?

System? Little System? Great System?

After confirming that I had neither a golden finger nor a System, I could only rely on knowledge from the 21st century to change my family's fate.
