[Xianxia world + Strong alliance + Transmigration between ancient and modern times + Feel-good story] The Three Realms are engulfed in a war. The parents of Long Shijun, a young woman of the dragon clan, sacrifice themselves to seal away her powers and memories, then send her to live among mortals. She is adopted by the Fang couple, who come from a family of traditional Chinese medicine practitioners, and given the name Fang Yuning. Dongfang You, the demon lord and tiger beast, is wounded in the war and hides in the Longqian Forest to recover. One day, Yuning goes up the mountain to gather herbs and comes across a white tiger caught in a trap. Unaware that it is the demon lord in his juvenile form, she rescues it and takes it home to raise. In his tiger form, Dongfang You guards Yuning day and night. Later, Yuning learns that the white tiger is the demon lord who drove her dragon-clan parents to their deaths, and she cannot forgive him. Xuancheng, the supreme ruler of the immortal realm, is false to his face and true to his heart. He tries several times to seize the dragon bones, but the demon lord sees through him each time. In the end, Xuancheng sets up a blood sacrifice to all living spirits. Dongfang You and Long Shijun sacrifice themselves, and their souls pass through several cycles before arriving in the modern era. Long Shijun’s soul enters the body of Lin Shining. Three months before the college entrance exams, she sets up a little study room in the Crown Nightclub to prepare, eventually helping the original owner take control of the Lin Group. In the process, she becomes entangled with Dongfang Xiuyuan, president of the Dongfang Group, only to discover that he is the resting place of Dongfang You’s soul...
