In the vast expanse of the New Great Domain, Yang Kai streaked through the void with Hua Qingsi at his side.
The two of them had set out alone, with no one else joining this expedition.
Having decided to create another Star Boundary, Yang Kai naturally wasn't one to dawdle. As the Commander of the Xuanming Army, he couldn't be away from the Xuanming Domain for too long.
Lingxiao Domain had no suitable World, so he had come to the New Great Domain to search.
"There's no shortage of Worlds in the New Great Domain, but only twelve of them are habitable, and at this point they're all pretty much packed to the brim." Hua Qingsi pointed ahead as she spoke. "That's the Youlan Realm. Around a hundred domains' worth of relocated human populations have been settled there."
Yang Kai looked up and saw a blue-hued World stretching across the void ahead. It wasn't particularly large, but the scenery seemed rather pleasant.
Originally, this World had only been home to creatures of simple intelligence, but after more than a hundred domains' worth of relocated human populations had been settled here, the entire Youlan Realm had come alive, with bizarre and wonderful structures visible everywhere.
The vitality of the human race was incredibly tenacious. Though they had been torn from their homeland and cast into this unfamiliar World, it would take only a few generations before the fires of humanity had spread across the entire realm.
The Dao depth of the Youlan Realm wasn't particularly high, but it wasn't low either. Cultivating here would pose no obstacle to reaching the Emperor realm, and the World's Heavenly Bottle was sufficient to support the birth of several Great Emperors.
Yang Kai didn't linger here, instead continuing to follow Hua Qingsi on her survey.
As they visited one World after another, Yang Kai gradually gained a clearer picture of the New Great Domain's overall situation. Just as Hua Qingsi had said, twelve of its Worlds were habitable, and each had received relocated human populations to varying degrees. A few of them, having absorbed too many migrants, were growing as cramped as the Star Boundary itself.
"Are there any other Worlds?" Yang Kai asked. Creating a second Star Boundary was actually quite simple — any of those twelve Worlds would suffice. Plant a Sub-Tree, and after a few hundred or thousand years, it would naturally become a second Star Boundary.
Back then, the Star Boundary had been on the verge of destruction, and even then the Sub-Tree's planting had made it a cradle for Open Heaven realm cultivators. The twelve Worlds here were all perfectly intact, so there was even less to worry about.
But Yang Kai had his own considerations.
"What kind of World is Palace Master looking for?" Hua Qingsi had no idea what Yang Kai was planning. "Apart from those twelve habitable Worlds, there are actually three more. Two of them have rather incomplete Heavenly Daos — ordinary people could be relocated there without issue, but if martial artists lived there, their cultivation progress would likely be very slow."
"And the third?" Yang Kai asked.
"The third World has a reasonably high Dao depth, but its environment is rather unique. On top of that, Great Demons roam freely throughout, many of whom possess strength on par with peak Emperors. Without a powerful expert stationed there, it would be extremely dangerous." Hua Qingsi explained.
It wasn't as though Lingxiao Palace lacked the ability to exterminate those demon tribes — a few Open Heaven realm experts would be more than enough, and the demons would have no way of resisting. However, that was their home territory, and if Lingxiao Palace were to actually do something like that, it would be an affront to the natural order. That was why this realm had been excluded when the relocated human populations were being settled, and had simply been left alone.
But Yang Kai's eyes lit up at the words. "Let's go take a look."
Hua Qingsi promptly took the lead.
Half a day later, the two of them arrived at the periphery of a World. Hua Qingsi pointed at the enormous realm and said, "This is the one. Lord Beast Martial named it the Myriad Demon Realm. When it was first discovered, Lord Beast Martial personally ventured inside to investigate and subdued several Great Demons, bringing them out. Those Great Demons are now capable subordinates serving under him."
The reason Lingxiao Palace hadn't moved against the Myriad Demon Realm was partly because it would have been an affront to the natural order, and partly because of Beast Martial Great Emperor.
Beast Martial Great Emperor pursued his Dao through taming beasts, so a place like the Myriad Demon Realm was naturally something he was very fond of.
Yang Kai gazed out and immediately understood what Hua Qingsi had meant about this World's unique environment. The entire realm was suffused with an extremely ancient Primitive Wildness Aura. No wonder the demon tribes flourished here and Great Demons were so abundant — in this kind of environment, it would have been far harder for them not to prosper.
Yang Kai was delighted by what he saw.
He truly hadn't known before that such a World existed in the New Great Domain. It must have been discovered by Lingxiao Palace after he had entered the Ink Battlefield.
"Let's head down and have a look." Yang Kai called out and led Hua Qingsi plunging into the Myriad Demon Realm.
Inside the Myriad Demon Realm, in that very instant, many Great Demons of profound cultivation seemed to sense something and raised their heads to peer into the void. But Yang Kai had deliberately concealed his presence — how could they possibly detect him?
The Myriad Demon Realm was enormous, far larger than any of the twelve Worlds Yang Kai had surveyed. Under his Spiritual Sense sweep, he indeed detected the auras of numerous Great Demons throughout the realm, each one comparable to a peak Emperor. Such powerful cultivation, combined with the formidable physical bodies of the demon race, made for quite impressive strength.
However, the demon tribes here had no contact with the outside world, so their cultivation relied entirely on instinct. Having reached the peak of the Emperor realm, they had essentially hit a dead end.
The current cultivation path of the human race descended from the Open Heaven method passed down by Cang and the other nine Martial Ancestors — condensing a Small Universe within one's own body to break through limitations and wield even greater power.
The cultivation of the Divine Spirits centered on purifying their own bloodline — the purer the bloodline, the more powerful they became.
As for the demon race, their modern cultivation involved taking human form and following the human Open Heaven method, allowing them to break through from the Emperor realm into the Open Heaven realm.
But the demon tribes of the Myriad Demon Realm had never even seen a human. How could they possibly know to take human form? Regardless of how profound their cultivation grew, they all retained their original demon bodies. Some of those demon bodies were staggeringly massive, creating a truly spectacular sight when viewed from afar.
