Revenge of the Dragon Lady

Lin Jun traveled through time inexplicably, and it was not unacceptable to change from an aunt in her twenties to a young lady of ten when she opened her eyes. But the beautiful sister who claimed to be my aunt told me while vomiting blood, "Your father's family destroyed your mother's family, your father killed your mother, and you have to avenge your mother. You have to hide your identity as a girl, otherwise you will be in big trouble...". "What's the trouble?"... My aunt turned into a bubble and disappeared. She may have died. "Ahhhhh one by one!!!" I originally thought it was just an ordinary time-travel novel, which was just an old saying at most. Why did I add a bloody revenge setting like "my dad killed my mom". Also, my aunt turned into a bubble. Is this a biochemical injury or a fantasy world? Aunt. Explain things clearly before leaving - one by one! !! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
