Qin Zhaoyue, a hundred-year-old Soul cultivator and famous artifact refiner, dies and transmigrates into a body of 16-year-old Xi Zhaoyue, who was killed on her wedding day.

The unlucky previous owner of the body was an illegitimate daughter of an influential family and was forced to live her whole life in the orphanage.

Hundreds of years later, in such a dangerous environment, people fought against the huge beasts and finally established the glorious Sumerian civilization.

The world crumbled, and city-states collapsed; had the gods descended to condemn the people?
