Zhang Yu's Cave-Heaven Production Line (Thanks to "DannySheng" for sponsoring a League Leader)

After suppressing the frenzied Corpse Parts production line before him and extracting the Grotto-Heaven Power within it, Zhang Yu discovered that he could control this mountain of flesh.

As he took control, he also received information transmitted from inside the flesh mountain, learning more about the frenzied Corpse Parts in the current Illusionary Realm.

"Can the frenzied Corpse Parts in the Factory Area be subdued as long as they are suppressed and their Grotto-Heaven Power is extracted?"

Zhang Yu thought, What was this? Pokémon? Digimon?

Sensing Zhang Yu's thoughts, Zhan Xian said, "This should be an extension of technology related to Grotto-Heaven Divine Beasts—or rather, Mountain-Protecting Divine Beasts." Zhang Yu's heart stirred. "Mountain-Protecting Divine Beasts?"

He recalled that the history of Immortal Dao Technique he had read did indeed mention that Sects in ancient times possessed things called Mountain-Protecting Divine Beasts.

Zhan Xian continued, "So-called Mountain-Protecting Divine Beasts began as merely breeding Demon Beasts in captivity. As the practice gradually developed, Immortal Dao Technique emerged that linked Demon Beasts to a Sect's Spirit Veins, even its Luck, ultimately cultivating Mountain-Protecting Divine Beasts."

"This technology developed rapidly during wartime. Especially after being combined with Cave Heaven Technology, it gave rise to Grotto-Heaven Divine Beasts."

Zhang Yu knew that Grotto-Heavens were like the independent space he possessed, and in ancient times, they were also called Secret Realms.

Many of Kunxu's Sects had once established their own Grotto-Heavens, created Secret Realms, and even relocated their entire mountain gates inside them. Zhan Xian said, "Simply put, it means using a Grotto-Heaven's enhancement to make Demon Beasts stronger while placing multiple restrictions upon them, so that they can guard the mountain gate."

Looking at the frenzied Corpse Parts production line before him, Zhang Yu said, "This doesn't look like a divine beast."
