Northern Border God of War Chu Lan, in order to investigate overseas criminal forces, conceals her identity and returns to the Chu family in Jiangcheng to trace her ancestry. Unexpectedly, the Chu family parents and fake daughter younger sister Chu Yin not only do not engage in wealthy family infighting, but instead shower her with ultimate favoritism and fierce protection. However, the Gu family and Lin family, supported by the Japanese Black Dragon Society, repeatedly launch murderous attacks against the Chu family in order to seize the top genetic editing technology chip left behind by Chu Lan's grandfather, even severely injuring the Chu family parents and causing Chu Yin to become deaf. Filled with righteous fury, relying on her heaven-defying martial prowess and Northern Border Commander identity, Chu Lan summons a fleet of excavators to crush the wealthy family conspiracy and purge the internal traitors.
