The Salted-Fish Supporting Lady's Daily Survival

[Sweet romance + raising him from childhood + devoted to each other + age gap + seemingly innocent but secretly scheming yandere]

After Chen Ruonan died from staying up all night reading novels, a System appeared and told her: her mission was to stop the yandere male supporting character from turning evil. So she started preventing his corruption while he was still young. She saved the tragic boy who had nearly had his heart cut out by his uncle, and was later thrown into a mass grave, then gave him love and support without reservation.

When the male lead lost his spiritual core, Chen Ruonan cut out hers for him.

When the male lead was bullied, Chen Ruonan secretly helped him get even.

Chen Ruonan thought she had raised a sweet, innocent boy, but she had actually raised a seemingly innocent yet secretly scheming black lotus. Who can tell me how my little white lotus became the boss of the demon realm?
