Hu Qingyao is a fox demon who has been practicing for thousands of years. Although she has not read any books about sages, she thinks she can be the founder of this world. Good news: She decided to hide her demon body and transform into a chivalrous woman walking around the world, experiencing human love and hatred. Bad news: Although she is smart, she is also a fool. She always offends the villain because of her "smartness" and is chased all over the street. Until she met Lu Chen by chance - a wooden knight who carried a heavy sword and was not very good at turning. As his name suggests, Lu Chen is as calm as a rock. He only fights head-on when it comes to fighting, but he is always upright. Not only does he help her fend off pursuit, but he can also always help her "make up her lies" with a sincere face when she sets up a trap to deceive others. Hu Qingyao: "Why are you helping me?" Lu Chen scratched his head and smiled honestly: "Master said that when the road is rough, draw your sword to help. Seeing you being bullied, I can't help it." Hu Qingyao looked at the silly man in front of her and thought: Although this man is stupid, he is easy to deceive and use. Why not take him home and become the husband of the village? As a result, there is a strange combination in the world: a vixen full of bad intentions, and a single-minded knight who specializes in dealing with all kinds of dissatisfaction in the world. Only later, when Lu Chen discovered the true face of the person beside his pillow, he was silent for a long time, silently put away his sword, and poured Hu Qingyao a cup of hot tea: "... The fox ears are exposed, keep them away so that no one can see them."
