Battle Formation Master: From Apprentice to Battlefield Commander

【Add this to your bookshelf and get rich!! + alternate world + light fantasy + leveling up + face-slapping and taking down scum + battlefield】 Holy crap! I helped an old lady cross the street and got hit so hard I became a vegetable. After lying there for twenty-three years, I finally regain the ability to move, and now you’re telling me I’ve transmigrated into a heap of corpses on an ancient battlefield? I’ve barely celebrated getting my limbs back when someone yanks me out of the corpse pile. “A battle formation master? A living one! You’ll do!” The general puts a blade to my throat. “Form a battle array! If we can’t hold the city, everyone in it, young and old, including you, dies!” What the hell?! I’m just a slacker apprentice! Fine, looks like I’m going to drop dead all over again! 【Ding! Iron-Blooded Battle Formation System activated!】 The System is here?!!! All right! If I’m going to die either way, I’ll fight you all! Defend the city? No! I’m going to rule it!
