I Come to the End in the Name of Fox Fairy

[Time Travel] + [World Destruction] + [Refreshing Article] + [Explosive] + [Explosion] + [Weird] I was born different from others. In the leap June of the year I was born, 19 new children were born in the whole village, but I was the only girl. Every year on the ninth day of September, I lose a layer of flesh all over my body like a snake. Yes, not only the skin but also the flesh, until the age of nine... I thought I could finally be like a normal person, but I didn't expect that the ninth day of September would come again and I would grow a blood-red tail... Unbelievable things happen one after another... Strange memories are revived little by little... Is my old self returning to reality? Or is the real me reincarnated in the past? Which one is real? How should I break the situation if it's true or false? Can you help me?
