The Female Protagonist's Immortal Cultivation System

My younger sister and I bound ourselves to Systems together. She chose the Leading Lady System, while I chose the Beloved by All System. But the Leading Lady’s missions were too difficult. After failing several times, her cultivation declined, and she became cannon fodder on the front lines when the beast tide struck. I worked hard and successfully completed my missions, making the leader of the Hehuan Sect give up his other lovers and pledge himself to me for life. As she lay dying, my sister clutched me resentfully. “Why do I have to struggle until I’m a complete mess and still get nothing, while all you have to do is please men to get everything you want?” We died together, then were reborn together. This time, my sister snatched the Beloved by All System first and sneered at me. “Big Sis, how hard can it be to seduce men? If you can do it, so can I!” I smiled. I’d wanted to choose the Leading Lady System all along!
