Ancient warfare, the rise of a warlord, and a minor System that does not make its host invincible.
His family is destroyed when he is sixteen. Forced into military service, he awakens the Heroic Spirits Summoning System.
There are no crushing victories. Every battle is a grinding mill of blood. He takes each stronghold and county one at a time. One defeat wipes out his main force and destroys years of hard-won gains. It takes years of painstaking work to rise again.
From five hundred routed soldiers to a full mobilization of a million, from a ruined mountain stronghold to ascending the throne and founding a dynasty. The Heroic Spirits provide wisdom and experience, not divine weapons from the heavens. Whether holding the line in heavy armor, suppressing enemies with crossbow formations, breaking through with cavalry, or crossing the river with a navy, every battle is won through coordination between military branches and the sacrifice of flesh and blood.
In the final battle, both sides fight with a million soldiers. The Wolf Lord is slain in battle, and the casualties number in the hundreds of thousands.
This is not the story of one person cheating his way to greatness. It is the story of a group of people gritting their teeth and surviving in an age of chaos, building their realm inch by inch.
