Renegade Immortal: I Become Wang Lin's Master and Ascend to Godhood

(After watching the anime, I became a huge fan of Wang Mazi, and that inspired this fanfic. Fellow fans, please go easy on me. You can also think of him as a different Wang Mazi, so there's no need to tie him too closely to the original.) Fang Zhiyi hatched from an egg. She doesn't know who her parents are. But she is a cultivation prodigy. Other people cultivate day and night and struggle just to reach Foundation Establishment. Fang Zhiyi eats and plays her way into the Deity Transformation realm. Others can only envy her. Still, Fang Zhiyi finds it a little boring being on her own. If she's bored, she might as well join a sect for fun. So Fang Zhiyi joins the War God Hall and takes on a sweet, innocent disciple named Ma Liang. But… Fang Zhiyi realizes that after her disciple returns from the Outer Realm Battlefield, he's become a completely different person? … Wang Lin's perspective: That possession went well. I got a demigod master for free.
