As the top killer of "Netherworld Pavilion", Shiqi only knows three things in his life: First, obey orders. Two, perform tasks perfectly. Third, the life and death of the task target has nothing to do with her. This mission is a bit strange. The organization ordered her to sneak into the East Palace to protect the rumored to be frail and out of touch with the world, His Royal Highness Li Yan. Protector? This is much harder than killing someone. Seventeen's first reaction was: trouble. Li Yan is even more trouble within trouble. She was hiding in the dark, but he wanted to call her to him and hand her a plate of freshly made sweet-scented osmanthus cake with a smile. "I know you're here. It's cold. Eat something warm." She blocked the poisonous arrow for him, but he nervously checked her wound first, frowning, feeling more sad than he was injured. "Your hands are more important than Gu's life." She looked violent when she killed, but he would wipe the blood from her cheek and say warmly: "Thank you for your hard work. From now on, Gu will be your scabbard." Shiqi didn't understand. She is a knife without emotion, a chess piece that can be abandoned by the organization at any time. But this man was like a little sun, stubbornly trying to warm up her thousand-year-old ice. When the organization's killing order collided with the instinct to protect him, Shiqi wavered for the first time in "obeying orders". Should she follow the organization that raised her, or should she protect the only warm sun in the world? This time, she wanted to choose where the blade went.
