"If you can become the master of the Nine Heavens Profound Mansion, you will have complete control over it, allowing you to enter and exit at will. As for your question about whether a hegemon who has ascended to the Ninth Heaven can leave the mansion, the answer is yes—at least until the core inheritance space is opened. Once that space is opened, the path through the nine levels of ascension is revoked," A-Jiu replied.
"I see. Senior, I still have many questions about this mysterious realm—this Nine Heavens Profound Mansion. For instance, it is said that all Laws of Heaven and Earth are sealed off to ascendants on the Seventh Heaven, and that merging the power of two Most Powerful Chaos Supreme Treasures can break this seal. Is that true?"
"Indeed. The cultivators who survived and escaped the Nine Heavens Profound Mansion in the past achieved it through that very method. However, no being has managed to do so for over ten billion years. Of course, if you become the master of the Nine Heavens Profound Mansion, you could rewrite the laws of every level, naturally lifting the seals on the Laws of Heaven and Earth. But in my view, the difficulty of passing the nine trials of inheritance is far greater than that of merging two Most Powerful Chaos Supreme Treasures. Regardless, now that the inheritance space has opened, the old path of ascending through the nine levels to escape is gone. Therefore, merging those two treasures would be meaningless," A-Jiu said.
