The ancient mountain god was the master of sealing all filth a hundred years ago. He used the Taoist temple as the eye of the formation and the godhead as the lock. He ended up with his memory broken and his incense cut off. Nowadays, he lives in modern cities under a pseudonym, collecting incense by receiving supernatural commissions, and he charges whatever he wants - a stick of incense, a copper coin, a sincere "please" will do.
"A Taoist temple does not have to be on a mountain, it can also be in a person's heart."
"The human heart will never be extinguished, and the incense will never be extinguished."
