Feng Lan was a Princess of the Dao Wind Imperial Family, and as such, knew what Celestials were. The same could be said for Guang San, who was the clan head of a prominent alchemist family.
Both of them knew of the higher realm that existed, as well as the beings who stood above immortals.
Beings of great power, whose mere presences could shake the entire Rust Sky World. Normally, most of them would never even get to hear the word Celestial, but there were a few that had the fortune of seeing them too.
Princess Feng Lan was one of them, and had attended the Immortal Court with her family where she had witnessed a Celestial. She still remembered the power they had, and how they could erase immortals as they wished.
It was a realm that she knew was too distant for her to even think of.
Even her father, the emperor of the Dao Wind empire, might not reach it if the fates did not allow it.
