Ethan Wei, the number one martial arts master, leads the border army in a three-year campaign, driving out foreign enemies and earning the title "Northern Sacred Marshal". To the outside world, Nigel's origins are unknown. Four years ago, guided by a mysterious person, he became Xia's number one martial arts master in one fell swoop. Since then, he has risen rapidly, sweeping away foreign enemies and becoming the veritable God of War. He is also highly valued by the head of state and several military ministers, and can be regarded as a national treasure-level general. But he has been quietly investigating his own background.
