My Yandere Junior Sister Ruined Everything

A yandere being crazy is nothing to fear. A yandere with brains is. After several lifetimes of forceful pursuit and possession, Hua Jianshang still can't have Ye Beixuan all to herself. What should she do? This time, she plans to take another path, one that will leave Ye Beixuan heartbroken and in unbearable pain! His junior sister, Hua Jianshang, is planning to destroy Yuanzhou because he ran away. What should Ye Beixuan do? He loves her, but can't stand by and let her destroy Yuanzhou, so he decides to stop her. By chance, he meets a mysterious woman named Ling. With her help, he successfully stops Hua Jianshang. What should Ling do when she loses to Hua Jianshang every time? She plans to kill her, but knows she can't do it alone. So she seeks out Ye Beixuan, pretending to help him while actually using him to kill Hua Jianshang. The truth is, Ling and Ye Beixuan's every move has been known to Hua Jianshang from the very beginning. She's even been playing along. Hua Jianshang: “Senior Brother, if you kill me and the child in my belly with your own hands, will you still be able to keep your composure? Hahahaha...”
