Who Let Him Become a Shaman? If He's a Shaman, Then What Am I?

[Farming + Slow-paced + Traditional fantasy + Semi-primitive] This is a world where the civilization of immortal cultivation has been lost, a world in its most primitive state. Here, there are shamans, mutated creatures, totem warriors, shamanic script, shamanic bone tiles, and shamanic power. Mo Shangyu transmigrates into the most respected shaman of a small tribe, even though he has never learned a single shamanic art from the previous shaman. But when he looks at the shamanic script before him, he freezes. Why would he need to study this? It’s just like elementary-school math problems. He can learn it with a wave of his hand. Carving shamanic bone tiles comes just as easily. How can this all be so simple? Things that take others three years to learn, Mo Shangyu masters in one night. Shamanic script that others spend a lifetime studying, Mo Shangyu masters in one night. “Will someone tell me who made him the shaman?!”
