After rebirth, Concubine Hua Nian Shilan, with the deep hatred and desolation of her previous life as a cold palace drinking poison, gave up her obsession with the emperor's favor and decided to start a peaceful life - to protect the Nian family and stay away from the power and intrigues of the harem. She changed her past arrogance and domineering attitude and took the initiative to extend an olive branch to Shen Meizhuang and Zhen Huan. The three formed a solid sisterly alliance and joined hands to fight against the hypocritical and vicious Queen Ulanara. From resolving the crisis at the Queen Mother's birthday party, to cleverly maneuvering to avoid trouble for her brother Nian Gengyao, to uncovering the Queen's conspiracy to poison the Queen Mother and helping herself ascend to the throne, Nian Shilan has taken every step of the way, but always sticks to his true heart and does not love power. She implemented a new policy in the harem to appease people's hearts, and even gave birth to the prince Honghui smoothly. After that, the three sisters worked together to uncover the counterattack plot of the remnants of the Uranala clan, and helped Nian Gengyao successfully surrender the entire family. As time went by, the emperor died, Honghui ascended the throne as emperor, and Shilan became the queen mother in that year, sharing a family relationship with Zhen Huan, Meizhuang, and An Lingrong. In the end, she passed away peacefully surrounded by family and friendship, completing her stable life away from disputes.
