Versatile Mage: I Have to Start over for a Forbidden Spell

As the Forbidden Curse Saint, An Shiran was invited by the chief of the American Magic Association to go to an ancient mausoleum to spy on the inheritance of higher planes. Several people unexpectedly obtained a mysterious dagger in the mausoleum against all odds. An Shiran, who thought the plan was a complete success, fell into the mausoleum at the hands of his colleagues at this critical moment. Opening his eyes again, An Shiran found that he was not dead, but had become an ordinary person who had not even awakened to magic.
