Cultivation of Immortal Heroine System

My sister and I bound the system together, she chose the heroine system, and I chose the heartthrob system. But the heroine's mission was too difficult. After many failed missions, her cultivation level declined and she became cannon fodder on the front line when the beast tide came. I worked hard to successfully complete the task, and made the head of the Hehuan Sect give up other interests for me, and be with me for the rest of my life. Before my sister died, she reluctantly pulled me, "Why should I have to work in vain and get no benefits, while you only need to please men to get everything you want!" We died together and were reborn together. In this rebirth, my sister chose the heartthrob system first and sarcastically said to me, "Sister, isn't it just about hooking up with men? I can do whatever you can do!" I laughed because I originally wanted to choose the heroine system!
