My Spiritual Bond Will Travel Through

The protagonist originally thought that he was just a kid king in a small town, longing to go to the big city, but his spiritual bond was very weak and could only be used once in his life. He longed to become a strong man, and was tempted to use a vicious spiritual summoning spell to use this mentality. He accidentally summoned the otaku on the earth. The two souls accidentally merged to form a new spiritual bond, and he became stronger step by step. This novel and its characters are purely fictitious.
