Traveling Through a Different World, the Companion Device Is Actually the Key to God

(Daily, funny, supernatural, campus. Except for the God Key, there will be no Honkai elements in the early part of the book) My name is Po Xiao. I woke up in the Abyss the night before. I traveled to a different world. The only difference between this place and the earth is that there is a companion device. Normal people only have one companion device, but I have 12! What can I do in a peaceful world? Of course it's barbecue! Wait, what is this? Holy shit! How come even the false god Otto was revealed! So I'm still falling apart?
