Time flew by. A month later.
Led by the Cloud Cliff Saintess, Li Yun finally formally stepped into White Emperor City.
Arriving at this true grand main city, Li Yun was filled with shock. It truly broadened his horizons.
Though it was also a main city within the Cracked Heaven Imperial Dynasty, White Emperor City was clearly far more imposing than any main city he had seen before. Its walls were taller, its buildings more magnificent.
More importantly, after entering White Emperor City, he could sense the auras of one Martial Dao powerhouse after another. Though every one of them was doing their utmost to restrain their aura, when those individual traces gathered together, they still gave him the feeling of a vast sea of smoke and waves.
This main city simply had not erupted yet.
Once it erupted, the energy it unleashed would absolutely be on a world-destroying level.
Compared to it, the Mysterious Moon Kingdom Imperial City was not even in the same league. It was utterly minuscule.
Interestingly, according to the Cloud Cliff Saintess, this was merely the surface.
After years of effort by the White Emperor Family, the true White Emperor City was already close to being forged into an independent Cave Heaven World.
What was a Cave Heaven World?
In truth, many independent small worlds had naturally formed across the Ancient Celestial Continent, wholly distinct from the surface world. Like bubbles, they were hidden in places difficult for others to notice.
Such bubble-like small worlds were Cave Heaven Worlds.
Though a Cave Heaven was small, it had all the vital organs.
The sun still set and the moon still rose. Everything that existed outside the Cave Heaven existed within it as well, and it could even produce Heavenly Materials and Earthly Treasures unavailable beyond it.
