Tomb Robber: in This World, My Family Is a Bit Ruthless

Jiang Shijie woke up in the troubled times of tomb robbery and fusion, and became the patriarch of a declining family. He set a rule: Starving to death is a small matter, but genocide is a big deal. Since we can't survive on the ground, we have to look for a way underground. When he discovers that the entire village is built on a huge "yin house", he leads his family on a journey to devour the tombs and change their fate against the will of heaven.
