Numbers One and Two are codenames given by Austin to the Dragon Vein Attendants for convenience in the army.
As Dragon Vein Attendants who have half-stepped into the domain of extraordinary power, they naturally don't receive the same treatment as ordinary soldiers. In previous battles, they mostly played the role of leading the vanguard. One could say the army behind them mainly centered its tactics around supporting their combat.
Soon, the troops split into three groups: one large and two smaller ones, according to Austin's orders.
"Attack!"
Without much delay, Austin directly ordered the army to attack.
With the strongest frontal force to crush the enemy, then the left and right wings strike forth, completely breaking the enemy's morale. Leaving one side open in a three-sided encirclement, offering an escape to dissuade desperate resistance from the enemy, would eventually lead them to flee backwards in defeat.
