Transmigrate to the Great Yu Flood-Control Era and Lead Human Civilization Forward

I transmigrated with an entire university library and became an obscure shaman serving Yu the Great.

On the day Yu the Great succeeded in taming the floods, it wasn't him the people knelt before, but the holy mountain of knowledge behind me.
