[Slice of life + transmigration + alternate history + BG + BL + CB + OOC]
An accident opens a time-space tunnel. First through are Yongzheng and Kangxi, and then...
"Huh? Why did the person change!"
When the person they hauled in turned into someone else, everyone in Kangxi's and Yongzheng's courts went into a frenzy!
No one knows who will transmigrate next.
Kangxi has just returned to the palace after staying at his son's home when he pulls a notebook written by Yongzheng from beneath his pillow. Thinking it must be about matters of state, he opens it and is horrified by what he reads: What do you mean, my son is sleeping with someone from his own household?
