Awakening of Supernatural Powers, Confessing Love to the Front Desk at the Beginning

The portal to another world quietly opened, and Sky Blue Star became the site for their conquests. The local creatures have become heretics that need to be eliminated, and a supreme god emerges to end this chaos. And the story takes place after the chaos. (This is my first time writing a book, and it's a serious one. The first 30 chapters are quite confusing. I suggest you skip reading if you see something you don't like. After that, it gradually becomes ok. This is just my personal opinion)
