As spiritual qi revives and rifts descend, martial arts become humanity’s last line of defense in protecting its cities.

From the school arena to the front lines of city defense, from Rift No. 4 to the battlefield among the stars, Lin Ran grins and draws his blade: Who says a good-for-nothing can’t defend the nation?
