A Lifetime's Lanterns, Returned to the Heavens

In her past life, she married Prince Lu Mingqing and helped him ascend the throne, only to end up with her entire clan slaughtered and a brutal death. When she opened her eyes again, she had returned to the day before their wedding—the day Lu Mingqing was cheating on her with her half-sister. This time, she married the dying Regent instead. She cured his poison; he shielded her from harm. A powerful pair, they plotted step by step, outwitting the hypocritical villainess, killing the traitorous scumbag, and vowing to take back everything she lost in her past life—including the empire itself.
