Mahavairocana

"Once one's cultivation reaches a certain level, one can remain imperishable even as heaven and earth decay."

Mahavairocana said:

"It's just a pity that I am still far from such a realm. Therefore, we must protect this heaven and earth where we dwell and cannot let it be destroyed. For this reason, Yellow Emperor Xuanyuan and I have fought these demons."

"Although we won in the end."

"But the price was a terrible one."

"You've seen the state of the God Realm. In that battle, countless gods perished, and the Demon World collapsed and fell outright."

"But as far as I know, after the battle between demons, monsters, humans, and gods, the Demon Realm had already collapsed, and the God Realm fell along with the Demon World. If the God Realm still exists now, does that mean the Demon Realm does too?"

"Your understanding is too one-sided."

Mahavairocana said:

"That battle indeed caused all the major realms to collapse. But a dark power is manipulating the Demon Realm. This power possesses the ability to heal, causing the Demon Realm to continuously repair itself."

"If Nüba had not guarded the gateway to the Demon Realm, it might have been completely restored long ago and returned to the mortal world."

Mahavairocana paused when he reached this point, then sighed:

"Nüba is a goddess of the Heaven Realm. Her Divinity and flames are the natural nemesis of demonic energy. If not for her, we would probably have decayed and perished long ago."

Only then did Ding Ling learn of Nüba's greatness. He could not help feeling a trace of admiration and asked:

"Senior Nüba told me to make a trip to the God Realm, saying that a god would teach me the Devil Subduing Method. Were you the Buddha she was referring to?"
