My name is Renn, and I am a down-and-out knight who doesn't even have a family crest. Baron Wald collected black money from the enemy, deprived me of my military exploits, and left me and hundreds of serfs on the front line as a human shield to attract firepower. Faced with the butcher's knife of the heavy infantry, I chose not to pretend to be a grandson and directly led the bankrupt serfs to mutiny! I taught the serfs to use a pitchfork to stab the lower third of the armor, and to use physical quagmire tactics to counter-kill the supervising team. Taking advantage of the darkness, I led people to set fire to the granary in the inner city. I led this group of "mud-legged men" to smash the baron's plate armor with an anvil and heavy hammer, and hanged him on the city wall in public. Facing Duke Lionheart's three thousand elite crusade, I dug out the ruins of the ancient empire and made a three-bow crossbow and the first version of black powder. When the sky-shattering explosion exploded in the heavy cavalry phalanx, pure-blood nobles across the continent began to tremble under my cannon and beg for mercy.
