The Male Lead's Path to Darkness

As the only white fox on Lianqi Mountain, Bai Yin was raised from the moment she became conscious to believe she was destined to become powerful and restore Lianqi Mountain to its former glory. But... she's a half-tailed fox. She doesn't even have a whole tail, and transforming into human form is a problem. How is she supposed to become powerful? Then one day, for no apparent reason, Bai Yin was sent away. The formidable fox mother waved goodbye to her through tears. "Study hard under the Immortal's tutelage. Once you've learned enough, you'll be able to stomp on the spirit foxes from other mountains..." But after spending several centuries together, Bai Yin discovered that the Immortal had turned evil! Wasn't he an Immortal? How did he become a demon? QAQ The male lead starts out an Immortal and later becomes a demon. The female lead is an adorable little fox. One-on-one romance, sweet and doting, happy ending. All names, place names, and official titles are made up. Please don't nitpick.
