Medieval Fantasy Revival

The beginning of sword and magic sets off the curtain of a new era. The faith of the church has become true, the rise of the gods has broken the order of the old era, and the era of theocracy has come, what will happen to mankind? The figure of the outer god is looming, and terrifying and crazy knowledge is secretly spread. Those who believe in it try to corrupt everything, welcome the arrival of the "god", and return to its embrace. Will the collision of worlds lead to destruction or rebirth? It all originated from a noble lord who traveled across time after falling into the water and was almost killed by the system.
