In his previous life, Zhou Mang was sold by his adoptive parents to be matched in a ghost marriage, ultimately ending in a tragic death by execution. Reborn in 1970, he awakens the divine sign-in system, possessing a portable space and an invulnerable body. Facing his blood-sucking adoptive parents forcing him to marry into a family to exchange for a bride price, Zhou Mang plays along with their scheme, tricking the villains into suffering the consequences of their own actions. Breaking free from the covetous plotting of the Li family relatives, he proactively signs up for the Northeast Barren Gully Production Brigade. Relying on extraordinary martial skills to crush evil people, miraculous medical arts to save the dying and heal the wounded, and becoming a forest ranger, he angrily rebukes all kinds of villains who trip him up, while also encountering the kind-hearted and beautiful Huang Xiaoyun, curing her foolish younger brother, and ultimately winning the beauty's heart. In the hard seventies, Zhou Mang carves out a thriving and counter-attacking life.
