Reborn the Holy Sword of Light to Scare Away the Devil at the Beginning!

When the modern liar traveled through time and became the Holy Sword of Light, he found that he had... No fighting ability? It doesn't matter, the fear value system tells him: the more afraid the enemy is, the stronger you are. A tentative slash caused the great sage of the demon race to be seriously injured and comatose; fear accumulated time after time, and the potential of the holy sword gradually awakened. This is a sword that thrives on the fear of its enemies, and a liar that thrives on wit and caution. The future of the alien continent hangs on the edge of his sword.
