Golden Sakura
Father is a seven-tailed white fox, and Mother is a five-tailed flame fox.
By all logic, with those two rolling the genetic dice, the worst child they could get should be a six-tailed fox. But Mother has given birth nine times, and each baby is a single-tailed earth fox.
The two of them think their cultivation simply isn't strong enough, so they train even harder.
The truth is, every child Mother has given birth to is a nine-tailed fox. It's just that Father's subordinate, Oscar Brown, switches them at birth and strangles them to death.
I'm the unlucky idiot who's died nine times.
By the tenth time, I cry and scream that I'm done. The Heavenly Way is so sick of me kicking up a fuss that they say they'll help me solve the problem.
I expect them to just strike Oscar and those fox cubs with divine lightning. Instead, they grant Father the ability to perfectly comprehend baby language.
When I open my eyes again, Mother is crying to Father while holding a scrawny, dark-furred earth fox. "Darling, it's all my fault. Our child only has one tail again."
Meanwhile, Oscar has hidden me in his sleeve. He's about to take me away to be disposed of.
In my panic, I shout in my mind, [Father, save me! Your subordinate switched me! I'm in his sleeve!]
Father, who is gently comforting Mother, freezes. He looks toward Oscar, who looks shifty, and says, "Stop right there. What's that in your sleeve?"
