A piece of starry sky emitting space-time fluctuations appeared before Lin Yuan as he closely observed the area ahead.
"Is this one of the three hundred and thirty-three entrances to the Xuanhuang Secret Realm?" Lin Yuan thought to himself.
The reason why human civilization did not monopolize the Xuan Huang Secret Realm was precisely because there were simply too many entrances to this secret realm.
Over three hundred in total.
And they were scattered throughout the universe.
For instance, within the Human Civilization Territory alone, there were nineteen Xuan Huang Secret Realm entrances.
"The Main Universe is vast and endless, and this 'vastness and endlessness' refers not only to its size but also to its myriad Spatial Layers,"
"Within countless Spatial Layers, it's possible for small worlds to be born, attached to the Main Universe, and these are the origins of the Cosmic Secret Realms."
