Mahwa

Looking for this manhwa where mc is godlike through an app (i think or a system) and he's able to give blessings and prayers. I know there was a part where he gave rice for food and rain for a drought? (Ants mightve been involved) ik there mightve been a girl who was a devout follower.
It's somewhat like nebula civilization in that sense.
It is not the japanese manga where he realizes npcs are real.
