"Shaoqing, what are immortals, what are fairies, you should have some guesses in your heart, right?" Xiao Jingsan spread his hands. He was wearing a robe like clouds and mist, like the wind swaying a jade tree, snow wrapped in a beautiful bud, really exuding some immortal aura.
Su Ming'an looked at the fairies around him, suddenly realizing that the fairy aura on them wasn't that awe-inspiring, but merely the air of ordinary people. It was Su Ming'an and the others' reverence for Penglai Fairy Island that initially gave rise to almost a faith-like feeling towards these fairies.
In other words, Xiao Jingsan was doing the same thing as the present-day deities—making people spontaneously generate faith in gods/immortals.
There were no gods/immortals in this world. It was only the strong power of belief from many believers that turned them into real gods/immortals.
Gods are products of human faith and expectation.
