Turned into a Little Girl, I Just Want to Cultivate Immortality, Stop Picking on Me Every Day

[Gender-bending transformation + yandere + everyday life + System + gender swap + cultivation + an invincible protagonist who grows stronger + an adorable little girl] Ji Yue used to be an ordinary male college student, until staying up all night grinding away at a game caused him to die suddenly. But that was exactly what led to his reincarnation! He also gained the strongest cultivation System! The unexpected part was that he had reincarnated as a girl, and would never grow any taller, remaining a little girl forever. On top of that, Ji Yue now had a yandere older sister. As a result, she got bullied almost every day... “Just you wait. When I grow up, I’ll pay you back a hundredfold!” But reality was so cruel, and Ji Yue realized she couldn’t beat her awful older sister at all. “Ahhh, I’m going to cultivate immortality! Stop bullying me every day now! O-or else I’ll use magic!” “Hehe, go on, give it a try~” Ji Yue’s sister, Li Xiaoxiao, replied.
