This "War God" title was given by the players, symbolizing supreme glory.
War God Lei Su, the first player to advance to Sword Saint, held the top spot on the Swordsman rankings for three consecutive years without ever dropping out of the top three. Back then, Blue Feather was far inferior. In this life, Blue Feather might just be able to compete with War God Lei Su.
In his previous life, War God Lei Su was always a mythical figure. The most memorable video for Nie Yan was during the Hilton Stronghold siege. War God Lei Su single-handedly duelled a level 260 Lord Skeleton King. At that time, he wielded the Swordsman's Divine Artifacts—two War God Crow Swords—and donned the War God Set. His strength was simply outrageous.
When Nie Yan was assassinating Cao Xu, it was the prime of War God Lei Su, a time when barely anyone in Conviction could rival him, except for a handful of individuals.
