I Transmigrated to the Tang Dynasty and Became Li Chengqian's Concubine

In the seventeenth year of the Zhenguan era, modern history graduate student Su Lingwei transmigrates into Shen Wei, a concubine in Li Chengqian's household. At the time, Li Chengqian's position as Crown Prince is in jeopardy because of his leg ailment and suspicions that he is plotting a rebellion. Using her modern knowledge and way of thinking, Shen Wei offers a "two-token strategy" to help him overcome the crisis. But political enemies such as Zhangsun Wuji and Li Tai, intent on protecting their own interests, repeatedly obstruct Shen Wei's efforts to help Li Chengqian. If she fails, Li Chengqian will lose his position as Crown Prince, and Shen Wei will lose her chance to change her fate and find love. As Shen Wei pushes for reform, her status as a concubine limits her, and she struggles with complicated romantic entanglements in the palace. Her enemies also repeatedly set her up, causing misunderstandings between her and Li Chengqian. At the crucial moment in the fight for the crown, time is running out, and betrayals and schemes abound. Shen Wei must resolve the misunderstandings while facing crises such as the "witchcraft curse" and protecting both her love and her ideals.
