After the whole family was executed, Shen Qingci lost his hair and changed his appearance, transforming into the "sick" young eunuch Su Xiaochen, and sneaked into the East Palace carrying the head. She has only one goal: to kill her enemies and overturn the Shen family's case! But the master she serves is the biggest joke in the whole capital - Xiao Jingyuan, the deposed prince who is suffering from mute disease, whose mother and concubine were humiliated, and who was abandoned by his father. Everyone said that the prince was weak and could be bullied, but Shen Qingci discovered something was wrong when he checked his pulse for the first time. This person has a calm personality and deep internal strength. How can he look like a useless person? Before she could test him, the "mute" prince, who couldn't even make gestures in front of everyone, forced her into a corner in the middle of the night, and rubbed her Adam's apple with his fingertips. There was no sign of weakness in his eyes, which were clearly a bottomless cold pool. "Su Xiaochen, your poison skills are pretty good, do you want to... Take a gamble?" From then on, she became the knife in his hand, and he became the shield behind her. She was poisoning, revealing secrets, and fighting against powerful officials in the previous government; he was playing dumb, forbearing, and setting up killings behind the scenes. Shen Qingci thought that his acting skills were flawless and he just waited for his revenge to be avenged before retreating. Unexpectedly, one day there was a palace change, and she was exposed in red makeup. She was about to run away, but she was picked up by the man who had been "paralyzed" for many years and put him in his arms. A low and hoarse voice boomed in her ears: "Mr. Su, you have cured Gu's poison. Where else do you want to run?" It turns out that hunters often appear as prey. He had never been mute, just as she had never been a eunuch.
