Li Qinwu tossed aside the unsharpened greatsword in his hand, picked up a water flask, drank several liters, and gave his assessment:
"Genpei, your fundamentals are solid, but your sword is too peaceful. It lacks an edge.
"This may have something to do with what your father taught you. Your sword only kills those who deserve to die. It lacks brutality."
