Shen Qinghuan, a master of metaphysics in the 21st century, was struck by thunder during a ritual that changed her destiny. When she opened her eyes, she became the legitimate daughter of a sick young man who did not care for her father and did not love her mother in the palace of the Great Xia Dynasty. What's even more terrible is that this body is naturally riddled with evil spirits, and he is an unlucky guy who will not live to be eighteen years old. The only way to survive is to get close to the humanoid plug-in who possesses a huge amount of "Ziwei Emperor Qi" - the current regent, Xiao Junhe. When they first met, she rushed to his side desperately, like a kitten stealing food, desperately absorbing the purple energy emanating from his body to stay alive. The man's eyes were cold and he pinched her neck: "Woman, what are you doing?" Shen Qinghuan's face was pale, but he smiled brightly: "Your Majesty, you are leaking, I will help you deal with it, you're welcome." From then on, everyone in the capital discovered that the regent, who was decisive in killing and not close to women, had a little tail that couldn't be shaken off. She can tell at a glance which house is haunted, identify which antiques are evil, and help people avoid misfortune with just a finger. When everyone laughed at the Shen family's eldest daughter for being a loser who only knew how to hug thighs, she had already relied on "eating" evil spirits and "absorbing" purple energy to become a master of metaphysics that everyone in the capital respected. The powerful regent also changed from "stay away from me" at the beginning to holding her in his arms every night and coaxing her in a low voice: "Huanhuan, is the purple energy today enough? Not enough... I have more."
