The protagonist Chu Potian was originally an undefeated god of war who had guarded the northern border for thirty years. He was jealous of the imperial court because of his outstanding achievements. In a key battle, he was cut off from food and aid by treacherous officials in the imperial court, and the entire army was wiped out. He was seriously injured and fell off a cliff, but accidentally traveled to a modern city and became a useless son-in-law who was kicked out by a wealthy family. At this time, the family he protected in his previous life was facing the crisis of genocide - strong enemies on the border were pressing on the border, and the family was leaderless. And his status as son-in-law in this life is exactly the "abandoned son" of the family that is about to collapse. When the two identities are intertwined, the protagonist arrives powerfully as a deposed son-in-law, starting a counterattack that spans two realms and crushes all directions.
