Apocalypse Paradise: I'm Actually the Strongest Supplier

I am my own most reliable partner, the one who will share life and death with me. Rich or poor, healthy or not, whatever the circumstances, I will stand firmly by my own side, accepting, respecting, and loving myself faithfully until the end of the world. Xu Xiaoman, from the modern world, transmigrated here with the post-apocalyptic Peach Blossom Haven System. At first, she thought she had merely taken over a stranger's body, until she realized: how could her own body possibly contain an outsider's soul? Xu Xiaoman of the apocalypse did not learn until the second before her death that the plot had swept her along and that she was destined to meet a predetermined end. Reborn in the past, she would change her fate. In the apocalypse, she would make herself an unshakable force, both in wealth and in strength.

What predetermined ending? She would change it herself.
