Wanted Across the Three Realms

How on earth did she, the mighty Demon Lord, end up being hunted across the world by the Immortal Clan? Liu Xia sat in a tree, resting her chin in her hand as she pondered this for a long while. As for the answer... she wasn't entirely sure herself. Perhaps she should start at the beginning and sort things out? The Immortal Clan has an Immortal Lord named Ying Zhi, son of the Immortal Emperor and lord of the Three Mountains Court. Yet he cannot overcome his tribulation. Having failed to attain the Dao, he even tried to get in through the back door and visit the Buddha Lady, but she turned him away for being too cold-hearted. He is missing parts of his three souls and seven spirits, and lacks the full range of human emotions. In short, he's a pretty ornament in the Celestial Realm. In Beiyuan, there's a demon lady who rules the Demon Clan. She spends all day shouting in the Heavenly Court, “I want land!” and “I want people!” They say she wants land because Beiyuan's soil is growing barren and its climate harsh, making it impossible for her people to live normally. As for wanting people... “R-report to the Immortal Emperor! Immortal Lord Ying Zhi has been... has been captured by that demon woman from Beiyuan!” After the Demon Lord fell into the mortal realm, she planned to live off others and wait for death. By chance, she got caught up in a case involving “alien demons” stirring up chaos in the human world. To uncover the truth, Liu Xia concealed her identity and enrolled in the Three Realms Academy, launching a new career as a class mentor. In other words, the Demon Lord of the Lower Realm has found a new job. But why is that strange new teacher named Shang Shi acting so odd? And what's with these unruly brats? She's the mighty Lord of Beiyuan, not a babysitter!!
