Ten Years in the Empty Chamber, He Regrets Too Late

Prime Minister's wife Shen Wan Yue was poisoned by her husband Gu Heng's white moonlight Lin Qingyan and died with hatred. Her soul witnessed everything that happened after. Gu Heng personally requested an imperial decree to demote Lin Qingyan from wife to concubine so he could welcome her back as the legitimate wife, and intended to move her out of the ancestral grave, causing his father to be humiliated and collapse. Just as the coffin was dug open and Gu Heng personally inspected the seal of chastity symbol, causing a uproar, Shen Wan Yue suddenly opened her eyes inside the coffin, reborn with ten years of misplaced devotion and the truth. Having returned from nirvana, she is now completely awake, no longer enduring, and begins to plan every step.
