[Western Crossover] I Wish to Become an Immortal

The heroine cultivates immortality, and when she transmigrates, she's completely lost. Her golden finger... please refer to the line above. The heroine's worldview is in shambles. As for the CP... the idea is still in my head, and I haven't stitched it together yet. 1V1, let's flirt. A few notes about the heroine: 1. She cultivates immortality, but please don't think of her as Chinese. She speaks a language no bird can understand. Just imagine her living on a vast, fictional prairie; 2. After the heroine transmigrates, her abilities work like a rechargeable battery. When she's fully charged, she's at the Nascent Soul stage; when the power runs out, she's just an ordinary person. Or imagine her mana bar; 3. What can someone at the Nascent Soul stage do? Well, whatever the plot requires, but she won't be stronger than Doctor Strange;
