Long Xiao had observed the battle between Pang Jian and Li Chu through other means.
In that battle, Pang Jian sacrificed his Immortal Primordial Spirit Body and pierced Li Chu's waist with the sharp edge of the Origin Demon Sword, proving to the world that he, a being of the Immortal Realm on Earth, also possessed the combat strength of a True God.
