(Not a harem, not brainless, not systematic)
This is an era where all races are competing for hegemony. The human race has the God of Wisdom who controls wisdom and deduction, the demon race has the Nine-tailed God who controls change, and the Mods have the Hell Demon God who controls conquest and plunder. Each race has its own god. For thousands of years, all races have lived under protection and demarcation. All races are intertwined. In this world, everyone can become a god, and I have traveled to this world.
Intention: The road to becoming a god
