I'm Truly Delicate and Sweet, but I Pretend to Be Useless

Bian Yang looks pure and delicate, but she's actually high-maintenance and difficult to care for. Each meal must be precisely 158 grams: one gram more gives her indigestion, and one gram less gives her low blood sugar. Her caretaker, A Si, finds her too much trouble and sends her to be cared for by her ancestor from three hundred years ago, along with a thick stack of Bian Yang's care instructions. The ancestor, Qiao An, has just turned eighteen and is so worried that handfuls of hair are falling out. Good heavens! How can a poor orphan like me afford to take care of her? To make money, Qiao An secretly signs up for the Empire's famous deadly reality show, Seven Days on the Edge. If she can survive seven days, she'll win a huge cash prize. The moment she boards the show's transport, she sees Bian Yang in a seat. Bian Yang: Surprise! Qiao An: What the hell is surprising about this? But quitting the show comes with a hefty penalty, and Qiao An has no money, so she can only grit her teeth and do her best to survive with her granddaughter. The moment delicate, weak Bian Yang appears, the audience in the livestream room decides she won't survive the first night. Sure enough, that night, contaminated creatures randomly select a "lucky" room. As it happens, the lock on Bian Yang and Qiao An's door is broken, and the creatures charge right in. Audience: See? She's about to die! The next moment, black flames ignite on the contaminated creature that has just stepped through the door. It manages a single scream before the flames burn it to nothing. Audience: !!! An ability user! Bian Yang softly praises her: Qiao Qiao, you're amazing! Qiao An: ??? What? What am I supposed to be amazing at? This ability has nothing to do with me! One comment from Bian Yang makes everyone believe Qiao An has awakened an ability. Because of her, no one dies during this season of the show, leaving the production team with a huge loss. Someone kidnaps Bian Yang to control Qiao An, then cuts off one of her little fingers. The pain curls Bian Yang's lips into a slight smile. Her blood hits the ground, and black flames instantly erupt. Hearing several screams from within the flames, Bian Yang sighs with satisfaction. "Fun." The flames return to her body, turning into a new little finger. People soon discover that Bian Yang cannot be killed. Hurting her only makes her stronger. The Empire's imperial family, battered by turmoil, needs Bian Yang's power. She ignores the princes' advances and seeks out the sickly crown prince. "If I help you take the throne, how will you repay me?" Looking at the ambition in her eyes, the crown prince replies, "I won't live another ten years, and you'll become the Empire's first empress to ascend the throne." Ten years later, Bian Yang becomes emperor. The granddaughter rises to glory, and the ancestor ascends to heaven. Qiao An becomes the Empire's youngest chancellor. Everyone knows that a chancellor must never refuse to do what they're told, or the emperor will step in and wipe them out in one fell swoop. Reading guide: 1.
