The Cosmic Secret Realm is a cheat for comprehending the Universal Laws, but it evidently has its flaws. Once the laws within a Cosmic Secret Realm are fully understood, there will be no more Universal Laws to comprehend!
Ying Yue encountered such with the Giant Spirit God before!
At this point, to continue understanding new laws, one must step out of the Cosmic Secret Realm and find a new one!
Unfortunately, Cosmics Secret Realms are extremely rare. Even in top-tier divine-grade civilizations like the Xuanyuan God Clan, only a select few are qualified to use them!
Marquis immortal grade, King Immortal, can use various Cosmic Secret Realms for free, while ordinary immortals must pay expensive fees.
Sadly, Thunder God and others, being ordinary immortals, can't afford it!
"Tens or hundreds of Hun Yua annually? That's too expensive!"
