A boy born to a noble family led a tragic life and in the end met a tragic death. The next time he opened his eyes he was in a world that resembled a VRMMO he played in his dreams. The inhabitants were ignorant even to the most basic concepts — concepts that would be considered common knowledge in a game — and kept on fighting inefficiently.
In this world our protagonist armed with his game knowledge acquires the strongest job class there is –the Sage — and proceeds to become the world’s strongest.
