In the first year of Zhenguan, Lin Suyu, the niece of Prime Minister Wei Zheng, entered the palace to be drafted. She was very good-looking and was chosen by Li Shimin, who favored her even more. She had been alone since she was a child and had no intention of fighting in the harem, but she aroused the jealousy of others. After repeatedly giving in, she still refused to settle the matter. Showing her arrogance and unruly nature, Suyu finally turned into the scheming concubine Ling in the muddy waters of the harem. After defeating a crowd of jealous people, Suyu lost his flesh and blood, and the frustrated Suyu was thrown into death row. Faced with the successive changes, Suyu finally made up his mind to regain favor. After facing the news of his father's death, the bad news of infertility, and the struggle all the way, he also lost the love of his life. He looked back and thought about the past and laughed, and finally hanged himself in the room after seeing through the world of mortals. Li Shimin couldn't bear it, so Suyu was removed from the history of history and watched over a past without traces.
