Looking for novels where Gods have to rely on their churches and faith and the MC cultivates to become a God and has his own church. Already read: Lord of the Mysteries Pivot of the Sky
Experimental Log of the Crazy Lich. Late chapters of Warlock of the Magus World. Later chapters of The Tutorial Is Too Hard.
Throne of Magical Arcana has both faith and magic based systems similiar to Lord of the Mysteries. Written by the same author. MC is of the magic based system Spoiler but in the later chapters he has also researched the power of faith.
