Transform into a Honkai Heroine's Life System

The male protagonist who destroys the world and loves to cause trouble the most* The female protagonist who is conscientious and lives up to her social status A sand sculpture~ In the harem novel "The Path of Immortals and Demons", the male protagonist's original eldest brother, Ling Fengge, did not cooperate with the plot and opposed the male protagonist at every turn - before the male protagonist had grown up, he was almost destroyed by this strong female protagonist. The current plot is in a mess and the world line is about to collapse. Chuan Shuju Wuhao System No. 021 Leyi's mission: ① Let Ling Fengge correct her mentality and find a heroine for the world. ② Maintain the basic line of the world and avoid plot collapse. Le Yi works hard and wants the heroine to return to her original path. While her heroine is in deep danger and narrowly escapes death, the male protagonist is stuck with her childhood sweetheart and is inseparable. Her heroine is about to die due to being sought for revenge, but the male protagonist is tired of Bai Yueguang and doesn't show up for a long time. Leyi: "..." Le Yi was also angry, no wonder her heroine was lying like a salted fish. What kind of bullshit heroine is this? Whoever wants to be a heroine should be treated as such! Le Yi felt sorry for his heroine. If the male protagonist doesn't feel sorry for the female protagonist, she does; if the male protagonist doesn't protect the female protagonist, she does; if the male protagonist doesn't love the female protagonist, she does! Le Yi sticks to the heroine every day, follows her obediently, brings her tea and water, and rides for her. By accident, she escorted the heroine to Mahadeva's place. ——The eldest heroine, she can be considered a heroine! Le Yi thought that he had retired from fame and was waiting to enjoy a wonderful retirement life, but suddenly an alarm came from Chuan Bookstore: "The system reported an error, the system reported an error, the system reported an error..." "The heroine script has been reopened, please be prepared for No. 021." "Gan!" Le Yi: There is a bug in the Chuan Bookstore system. They told me that the "female protagonist" I wholeheartedly protected was actually a man. He killed the original male protagonist. What should I do? Thanks for the invitation, of course I will be the heroine. — Ling Fengge was always fearless. His reputation was ruined by Xiao Sheng, but he didn't care; his luck was robbed by Xiao Sheng, and he laughed it off. Until that bitch Xiao Sheng took a fancy to the little girl who had been following him. Ling Fengge, who had always remained calm before Mount Tai collapsed, leveled the mountain with one sword.
