Dressed as the Vicious Sister of the Male Protagonist of a Harem Novel

I didn't add QR codes randomly, and I didn't write long comments or talk nonsense. Who would have thought that Jiang Yuan would actually travel through time! Just travel through time, it doesn't matter. But what happened to the vicious sister of the hero Jackie Chan Aotian who traveled through time? It's okay, the most important thing in life is to be aware of current affairs and be a hero. But that cute system, why do you issue all these tasks with all kinds of weird punishments? In desperation, Jiang Yuan, who originally wanted to hug the male protagonist until the end, left her father who regarded her as his treasure and went out to practice alone. Before he could get any results from his training, he heard the news that his father asked him to join the Xingheng Sword Sect... Listening to Tongzi asking her to choose one of the two, Jiang Yuan had no choice but to listen to her father's arrangement. But who will tell her why this senior brother of the Xingheng Sword Sect is the beauty she just made fun of? Listening to the other party's words about bringing her own dowry and leaving with her, Jiang Yuan was helpless. She really couldn't compare... The evil sister who likes fluffy vs. The villain who is fluffy and has a dark heart
