The Primordial Spirit Brand is entrusted here, protected by the Saints of the Fire Cloud Cave. Even if killed, one can be reborn through this Primordial Spirit Brand.

Fortune is exceedingly mysterious; even if great fortune converges, without a supreme treasure to suppress it, fortune will eventually leak away, much like a mortal's lifespan, ebbing away gradually.

The Fire Cloud Cave is a sacred land of the Human Race, and one can use the Cave's power to suppress one's own fortune to slow its loss.
