Zhu Huan's Wei Zi Novels

Returning pearls during the Yongzheng period (unfinished, more to chapter 1 12): The emperor has had a hard time these days, and going to hell is actually a debt. It's a pity that it's hard for dad to do it, and he has to wipe his son's ass when he dies. Hey, just clean it up. Who knows that in the blink of an eye, the male body becomes a baby girl. But if you can't resist, you can only adapt, but don't dress up as your son's illegitimate daughter. Listening to my son's foolishness in infancy and thinking about his hard work in his last life, this day is impossible!

There are several characters who belong to Dai Ziwei in Yongzheng, so I can't remember clearly.
