Bound to the Love System, the Yandere Sister Is Out of Control

After traveling to the world of cultivating immortals, Gu Mingxuan bound a golden finger. However, the golden finger that was supposed to help him get rid of his sister's "yandere crisis" was brought to the wrong system. In other words, I want to improve other people's favor in front of the yandere! ? … Gu Mingxuan was about to knock on the door when he suddenly felt an extremely cold gaze behind him. He turned his head stiffly and saw Jiang Ruoxi standing in the distance, with the corners of his mouth raised slightly, revealing a smile that was familiar but made his scalp numb. "Brother, what are you doing?" She asked softly, her voice soft, like a coquettish kitten, but there was a suffocating chill in her dark eyes. Gu Mingxuan suddenly broke out in cold sweat, and said with a dry smile: "Ruoxi, I, I was just walking around casually." "Oh~ Really? But why, I feel like my brother is avoiding me?" "Brother, you won't... Go behind my back and have a good relationship with someone again, will you?" She tilted her head, her eyes gradually darkening. Gu Mingxuan's palms were covered in cold sweat, and his heart was filled with despair: "It's over, Tongzi, save me!" … Many years later. Jiang Ruoxi: "Husband, why are you back so late?" Gu Mingxuan: "What!" Jiang Ruoxi: "Oh~ I won't ask anymore. Husband, don't get so angry." Also known as "Strategy for the Empress, I'm Trying Crazy on the Edge of Death"
