Uncle Jiu's World: From the Start, I Beat the Drought Demon to a Pulp

I transmigrate into Uncle Nine's world, and on my very first day, I witness Uncle Nine battling a drought demon. What? Uncle Nine is no match for it? No problem, I'll trade with the System for a Five-Thunder Righteous Heaven Talisman. Bronze-armored corpses, gold-plated infant corpses, black-gold infant corpses... I'll smash them all with a single punch.
