In a world where the strong are respected and families control everything, martial arts and power are intertwined.
The protagonist is a "wasted son-in-law who comes to visit" and is looked down upon by the entire city.
No one knows that he is the only descendant of the Hidden War Temple, who rules hundreds of domains, and is titled "The Strongest in the Human Race"!
Three years ago, he concealed his identity and became his son-in-law. Three years later, a word came from the temple:
"The Lord of God returns to his throne and slaughters the city by himself!"
