Fantasy: I Turned on Infinite Defense

As strong as you are, I can control the field. A frustrated boy traveled through a fantasy world and successfully awakened the infinite defense system. I heard you are good at fighting? Sorry, it doesn't work for me. The Holy Lord is here in person? Just stay somewhere cool. Lord of all things? Sorry, you don't have a chance to show off to me. What? I heard you want to kill me? Do you think I care about you? Everything can be laughed off, but if you bully me, I'll beat you until your own mother doesn't recognize you. This novel and its characters are purely fictitious.
