Adorable Disciple, Bewitching Imperial Preceptor

They say the Imperial Preceptor of Donghuang has a face as flawless as jade and eyes like bright stars, like a god descended to earth. They say the Imperial Preceptor of Donghuang has boundless magical powers and can shape the fate of the realm with a wave of his jade-white hand. They say the Imperial Preceptor of Donghuang wears a silver robe, with long, dark hair cascading like a waterfall, and a bewitchingly beautiful face. Yet the Imperial Preceptor took the unruly Ninth Princess as his disciple. He descended to the mortal world to undergo trials, with no set date for his return. As long as he remained in Donghuang, he would protect her. The arrogant and domineering Eldest Princess bullied his little disciple. With a quick calculation, he saw that her fate clashed with His Majesty's, so he promptly arranged for her to marry a prince from another kingdom. The young marquis, a notorious womanizer, tried to take advantage of his little disciple. The Imperial Preceptor had His Majesty marry him off to the promiscuous daughter of the prime minister's concubine. A handsome man set his sights on his little disciple. The Imperial Preceptor gave him a cold glance. The Ninth Princess's fate was too strong: ordinary men simply weren't suited to her. Everyone knows the Imperial Preceptor always takes his little disciple's side. What! This lord is an immortal who never ages or dies. The little girl didn't know any better. She asked the handsome man before her to hold her, and from then on she toddled after him, sweetly calling him Master. Master, A Jiu wants a hug. How had Feng Qi, who'd kept his dignity intact all his life, ended up losing it all to this shameless disciple? [Demon Lord] The little disciple stroked her chin, staring wide-eyed at the handsome man before her. “Master, this big sister is so pretty.” The Demon Lord looked at the sweetly smiling little girl. “Since you think I'm pretty, why don't you come with me from now on?” The little disciple snorted. “This princess doesn't need a big sister. I only want to stay by my handsome, wise, and peerless Master's side.” The Demon Lord was speechless. He was the mighty Demon Lord, so how had he lost to that fortune-telling Imperial Preceptor? Is that so? A certain man smiled. Who else could ever handle her? [Phantom] In the dark of night, a man in red stood alone, apart from the world. “Xiao Jiu, have you forgotten me?” You shouldn't have forgotten me. Then I'll punish you with nightmares, night after night, until the day you remember me. A prince of a different surname died young, yet returned as a phantom to haunt her dreams each night. Xiao Jiu, my Xiao Jiu, I've already fallen into hell. I won't let you ascend to heaven in peace with someone else. A devoted, one-to-one romance with no angst and plenty of affection. Welcome!
