A world where magic-wielding elves and their centaur subordinates reign as the "Dominant Species."

All other races are scorned as "Inferior Species," living under unjust rule and exploitation.

Liam, a young boy born and raised in a remote village, is one such "Inferior Species." However, his humble daily life comes to an end when the capricious violence of the Dominant Species reduces his family, his home, and everything he knows to ashes.

On the brink of despair, Liam awakens. It is not a power of sword or magic, but another kind of strength—the memories of his previous life as a "military strategist," cultivated as a professional soldier and specifically a military bureaucrat, encompassing science and technology, modern military doctrine, jurisprudence, and economics.

The weapon he now wields is "knowledge," a vast and dangerous power unknown in this world.

Not for revenge, but to forge with his own hands a nation where all people are equal under the law, one that will never again yield to injustice.

Flying shuttles will dismantle existing industries,

finance will reshape economies,

dams will foster cities,

machine guns and howitzers will shatter the pride of knights,

chemistry will overpower the miracles of spirits,

weapons of mass destruction will even be employed,

and law will negate all authority and power lacking the trust of its citizens.

This is the founding chronicle of a man who, though branded a "Demon King," nonetheless establishes a superpower where science and human rights flourish, and various peoples coexist—a record of both his merits and his sins—a record of a liberal, independent nation born from a pitiful man who was too rational, too ruthless, and suffered more than anyone from his own actions.
