(Dual transmigration + strong female lead + comedy + strong male lead + golden finger + System + occasional soul-swapping between the male lead and supporting male characters + scheming male lead + devoted husband) Jian Qingqing transmigrates to a place called the Seven Northern Kingdoms, also known as Great Qin. The people there revere cultivation and the pursuit of immortality. Everyone has a protective disc in their body bearing a special mark, which keeps their spiritual roots from being damaged.

When she learns that her eldest sister’s fiancé, Prince Zhongqin, has returned from the battlefield blind and crippled, her father forces her to take her sister’s place as the bride. And so the story begins...
