Shen Qingci, the descendant of a modern family of medicine and poisoners, traveled through time after a plane crash and became Su Qingci, the fat eldest daughter who was poisoned in the Prime Minister's Mansion of the Dasheng Dynasty. The original owner was poisoned by Aunt Liu for eleven years, weighing 280 kilograms, her meridians were sealed, and her mother was ill in bed.
She awakened to the Nine Heavens Spiritual Ruins - a portable space with spiritual springs, spiritual fields, and bronze alchemy furnaces. Relying on the Lingxu Formation Fire, she regained her poison-healing skills, detoxifying and counterattacking at the same time. Lingquan detoxifies, silver needles unblock meridians, and alchemy refines the body—reborn within three months.
On a full moon night, Ye Chenyuan, the young master of the God Clan covered in blood, climbed over the wall and fell into the side courtyard. He has been under the God Eclipse Curse of the Dragon Clan for twenty-two years, and is said to not live until twenty-five. He also has a political engagement with a princess of the Feng Clan. The two made a deal: she would detoxify him, and he would protect her.
Going all the way north from the Prime Minister's Mansion, she discovered that she was involved in more than a simple revenge - a power game between the six major divine clans that spanned a century. The Dragon Clan's secret chess infiltrated the northern territory of the Ye Clan, the earth's marrow veins, and even the death of her maternal great-grandfather, all on the same chessboard.
She has to cure more than one poison - there is also a dead end that spans six clans.
