Demon-Hunting Genius Mage - Chapter 68

Reborn into the world of Yugioh, it's natural if my goal is to become the best duelist!

Zhang Ye was originally a mundane college graduate with aspiring dreams to become a star, but unfortunately has below average looks and height. However one day, he woke up and suddenly found himself in a parallel world!

“When the old gods are forgotten, they do not die—they wait.”In the year 1025, the Viking Age wanes.Iceland bows to Christ. The Althing governs by law. And the gods of old fade to whispers.But in the far Westfjords, something stirs.Vetrulfr, a former Varangian captain and exile, returns from the East with foreign gold, forgotten warcraft, and a hunger no man can name.He comes not in peace, but to raise Ullrsfjörðr from ash and ice; building walls, carving runes, and waging war on behalf of a dying faith.From Reykjavík to Aachen, rumors spread: a ghost walks the North once more. Some call him the son of Ullr. Others, a wolf-cloaked demon.But all will know his name.and when the Valkyries call, he will answer.

He became a teacher at the best magic academy in the empire.
