Different World Reincarnation as a Sage

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 embarks on a quest to become the world’s strongest.
