Author: Shinkou Shotou

Illustrator: Shibano Kaito

Genres: Action, Adventure, Fantasy

Translation: LightNovelsTranslations

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.

Update: v08. The volume was completed quite some time ago but I forgor.

TLDR: WN translation until around halfway through v05, then it switches to LN because the WN was discontinued. First 5 volumes aren't split because the order of the events in the WN is different.
