Forced to Become the Immortal Lord's Dark Moonlight

As the old saying goes, Heaven has nine levels, and those who dwell in the Ninth Huaxia Heaven are immortals. When an immortal is banished to the mortal realm, they become an exiled immortal and forget all about the Ninth Huaxia Heaven. They must cultivate the immortal path anew to return, and without someone to guide them, they may never make it back. Zhan Yuan was one such exiled immortal, and the imperial preceptor of the mortal realm. Before she could even figure out how to cultivate anew, her soul was shackled and sealed, and she was pierced through the heart by ten thousand arrows. An accident gave her a second life, and she retained everything from her past as an exiled immortal, yet somehow could not remember that man's face. Who was it in her previous life that wanted her forever condemned to the pillar of shame, unable to find salvation? Since she could still enter the cycle of reincarnation and be reborn, she would hunt him down. Alive, she'd destroy him; dead, she'd dig up his grave!
