Heir to the Demon Realm

Once upon a time, there was a little demon lord. He died, then "came back" to life. To uphold justice, he joined a group of righteous cultivators to fight the boss, only to discover... Huh? Wasn't the boss they were supposed to defeat... himself? His long-lost sister: Bro, I've fallen for your master. Help me win him over. His dad, just woken from a long slumber: Son, when are you going to rule the mortal world? His once aloof subordinate: I'll slaughter everyone in the mortal world to avenge you! The little demon lord: ...I just want world peace. OTZ Pre-release 1: You Don't Have to Save Me Bai Yu has a secret: He knows everyone's secrets. His younger sister dozes off in class because she secretly works part-time as a magical girl at night; His childhood friend, who's a little too effeminate, has the soul of a girl and isn't secretly in love with him. He's just trying to fulfill the KPI for his Harem System by collecting affection points; The ordinary guy next door is constantly getting possessed; And the fortune-teller, Blind Xu, outside the market really is a half-immortal who failed his tribulation. Bai Yu: ...I often feel like I don't fit in with you all because I don't have a secret identity. One day, a transfer student joins their class. Tall and long-legged, with a rebellious look and eyes that regard everyone as if they're already dead. But when he sees Bai Yu, his eyes suddenly light up. During PE, a basketball hits Bai Yu on the head. Several boys hurry over to apologize, but the transfer student kicks them all to the ground. Holding Bai Yu protectively in his arms, the transfer student says fiercely, "No one protected him before, but now I'm here. I won't let you hurt him again!" The boys: "..." Bai Yu: "..." A character card appears above the transfer student's head: Xuan Feng, a transmigrator into a book, objective: Save Bai Yu. Bai Yu: ? The principal: "Next, let's welcome Bai Yu to the stage to receive his award." Xuan Feng glares. "Hmph. What a despicable villain, trying to humiliate you in front of everyone." His younger sister: "Bro, have you seen my lipstick?" Xuan Feng: "Hmph, your evil half-sister is always coveting your things." His childhood friend: "Meet me after school so we can compare answers." Xuan Feng grabs Bai Yu's hand, his eyes red with fury. "That scumbag's already involved with your half-sister. He doesn't love you! He's just using you!" Bai Yu: "..." Maybe you should stop trying to save me. Pre-release 2: The Young Master and His Bodyguard Xiao Heng used to be a low-ranking figure in the martial world. After accidentally transmigrating to the 21st century, he used his inner strength to become a bricklaying champion who ruled the construction site, easily earning tens of thousands a month. Xiao Heng happily calculated that he could buy a house in two years and start a family in three. A wife, children, and a cozy home were just around the corner. Who could have guessed that after he accidentally rescued a handsome, well-dressed man one day, his carefully planned perfect life would begin to go off the rails? Xiao Heng at first: Hah, there's no way I'd fall for a man this fussy. Xiao Heng later: He's actually great! As the heir to the Song Group, Song Jingyu lives a life of luxury, looks down on everyone, and naturally expects to have the best of everything. That should include the perfect lover. Perhaps a brilliant new star in the business world, perhaps a dazzling movie star, or perhaps an upright and refined university professor... He eagerly awaits the match fate has in store for him. But the perfect lover never appears. Instead, Song Jingyu ends up trending three times, each time linked to the same construction worker who barely finished school: The first time, the worker saves him; The second time, his lifesaver becomes his personal bodyguard; The third time, he marries his bodyguard. Song Jingyu's response: Oh wow, how exciting. Theme:
