In her previous life, she was the only daughter of General Gu Yan and the eldest daughter of the Gu family. She had a noble status but a soft temper. She mistakenly believed in Xie Yan's promise of "a pair for life" and told him all about the Gu family's defenses, connections in the court, and even her father's hidden worries about the imperial power. She thought it was a good match, but in fact it was a trap - Xie Yan was a dormant chess piece of the Xie family. She used her hands to dismantle the Gu family's power, and then helped the Xie family to completely overthrow their relatives on the grounds that the "Gu family collaborated with the enemy".
On the day the city was broken, she was locked in the Gu family ancestral hall by Xie Yan himself. She watched her clan members being massacred, and her father called her "idiot" before he drank poison and committed suicide. Xie Yan stood in the firelight and handed her a glass of poisonous wine: "Nian Sheng, the Gu family is blocking the road. You and I... Are on different paths." When she drank the poisonous wine, she dug her nails into her palms and swallowed the blood mixed with the poisonous wine: "Xie Yan, if there is an afterlife, I will make you Xie's family, pay with blood, and I will make you... Feel the pain in my heart today!"
