Consecutive Falls

Why was it the Foreign Realm invading the Celestial Realm, and not the other way around?

This was because their heaven and earth was superior, and they also had a larger number of elites who possessed a more powerful battle prowess. Thus, they were the invaders.

"However, the essence of the different heaven and earth are the same," Ling Han remarked after carefully mulling over it.

Compared to the Celestial Realm, the Foreign Realm had one more Regulation—darkness.

When the Regulation of Darkness was unleashed, it would cause one to enter a state of wild frenzy. At the same time, it would also strip one's vision and divine sense. It was an extremely powerful Regulation.

The Celestial Realm didn't possess this Regulation.

During this one month, Ling Han didn't do much. He simply spent tens of thousands of years in the Black Tower to extract a sliver of Regulation of Darkness.
