When Lin Xiao's incarnation stepped out of the Door of Space, he immediately felt countless beliefs, emotions, and obsessions tightly enveloping his avatar. With a wave of his hand, he summoned a Divine Shield to block out all these distracting thoughts.
These beliefs, emotions, and random thoughts arose from the consciousness of his followers. As he ascended to Medium Divine Power, amalgamating all the Godhood and strength he possessed, he naturally attracted these thoughts. Upon entering Starworld, this sense would be exponentially stronger. The more powerful he was and the more followers he had, the more such consciousness waves would become diverse and numerous.
This is why Deities, upon losing their Divine Power, would so easily fall into Starworld and ultimately meet their demise.
His entrance into Starworld this time proved fortunate; he discovered no active Star Realm Beings around, let alone Divine Aberrations.
