[Western Fantasy + Multiple Races + Invincible Protagonist + Continent of Gods and Demons + A World of Myriad Clans + Decisive and Ruthless]
God has two hands: one is the Church of Light, the other Satan's dark power.
Through threats and temptations, they seize the faith of the entire continent.
But one person came along and turned the whole continent upside down.
From then on, gods and demons were forbidden to tread here. I rule this continent.
An angel descends, and I snap its wings to make soup.
A demon descends, and I break off its horns to make beads.
Don't mess with me. I'm in an extremely foul mood...
