[Currently updating: Socially Anxious and Transmigrated into a Torture Novel as a Hostage Prince. If you're interested, feel free to add it to your favorites.] Ji Zhan has recently become obsessed with a fictional character in a book. The man is breathtakingly handsome, but cursed with a terrible fate. His childhood was full of hardships, and as the villain, all he can do is make way for the male lead. Ji Zhan dreams of holding him close and shielding him from suffering, so he can remain forever bright and carefree. When Ji Zhan opens his eyes again, he has arrived in the world of the book. He sees little Rong Li being beaten and rushes to the rescue. Just as he saves little Rong Li and reaches out to pinch his cheek, he jolts awake in bed. Ji Zhan: “Holy crap!” After that, he dreams about Rong Li several more times. He thinks they are just dreams, until one day he really does transmigrate into the book, becoming Ji Zhanbai, the godson of the greatest powerhouse in the cultivation world. As the biggest beneficiary of connections in the whole book, the male lead is his underling, the female lead is his sister, and every great immortal-world powerhouse is either his godfather or his real father. Ji Zhanbai declares: “Who dares stop me from saving the person I want to save?!” Everyone looks at Rong Li, protected behind Ji Zhanbai: “Come out here if you've got the guts!” Ji Zhanbai: “You come over here if you've got the guts!” Everyone trembles. “You think we're afraid of you?” Ji Zhanbai raises an eyebrow. Everyone flees in panic. “Yes, you, you exactly! We're just keeping our distance!” Rong Li smiles warmly. “Master, you're so good to me.” He smiles as if nothing could trouble him, but Ji Zhanbai gets a chill. You can repay me if you want, but I don't want your body! Rong Li carries him away with a smile. “For such a great kindness, I can only repay you with myself. There is no other way.” Ji Zhanbai: “...” Betraying one's master and ancestors! Betraying one's master and ancestors! Rong Li: “Once, Master protected me and saved me. From now on, this disciple will stay by your side forever. Anyone who dares to bully you will pay a hundredfold.” A black-hearted, possessive, jealous, sweet-talking top X a gentle, beloved master who has less than zero emotional intelligence Theme: No matter what difficulties you face, always persevere and embrace the sunshine.
