What he has is not ordinary ears, these are a pair of super ears that can hear ants yawning. Everyone thought he was incompetent. The only effect of his talent was to strengthen his hearing, so he was imprisoned in a high tower sealed by a barrier and became a "tower otaku". However, don't underestimate this otaku, his life in the tower is not just about playing games and ordering takeout. He discovered that his ears could not only hear, but also "eavesdrop" on magical chants. He was simply an "eavesdropper" in the magical world. Not only did he secretly learn the magic of the world, but the chants of the gods in the sky became his "ear welfare". He accidentally mastered the legendary super magic and became a secret "magic world celebrity". More than ten years later, Als finally decided to walk out of the tower, but he knew nothing about the outside world and had little understanding of his own superpowers.
