In the Name of God: Kill God!

In his previous life, a lonely young man with rich knowledge died of internal conflict. In this life, he was entrusted by the gods, grew up in a vulgar way, and was ready to go into another world. He started all kinds of wonderful adventures in order to eradicate the final boss! (The protagonist has a big gift package at the beginning, but it is not a brainless novel. The villains almost all have brains, so this is a story where the protagonist develops secretly and finally saves the world. Thank you for watching!)
