Lu Changsheng's thoughts gradually became clear. Domain Fusion is the way forward!

Long Yun had shown him just how powerful fused Domains were. Once Domains were fused, the resulting amplification was massive, as power could be amplified by ten times with just the fusion of two Domains. If three Domains were fused together, the amplification could reach twenty times. Four Domains could bring it to thirty times, and five to forty times, and so on.

If the martial artist could fuse five Domains, that forty times amplification would be equivalent to forty layers of ordinary Domains.

Lu Changsheng was struck by a sudden realization. This was the true cultivation path for top-tier Divine Treasury experts. It was no longer about the number of Domains; what mattered was their quality—or rather, the possibility that they could be fused.

With that approach, even a small number of Domains could boost his combat power. By contrast, those who relied on many ordinary Domains often lacked depth and could easily be identified as someone not from a major sect.

This was where the foundation of sects and great families came into play. Such forces had established methods to fuse Domains. By following those methods step by step, they could steadily fuse their Domains.

Still, I can't leave out the ordinary ones. If I can comprehend them, I should. The more, the better, since it affects how fast my Mind Space expands. But at the same time, I also need to work on Domain Fusion.

Lu Changsheng thought of his Starry Sky Waterfall Domain and Waterspout Domain. These were both fused Domains, but that was all. He could only achieve two fused Domains. To fuse one more with them was nearly impossible.

Despite his level of Perception, fusing Domains from scratch remained extremely difficult for him. For that, he would need to rely on the experience and insights left behind by any seniors.

"When it comes to backing, I've got the sect behind me. The sect is a dominant force, and its foundation is no weaker than any martial sect. When it comes to Domain Fusion, the sect definitely has plenty."

With that thought in mind, Lu Changsheng headed straight to the Transmission Hall. As a true inheritor disciple, he had access to all martial arts and secret techniques stored there. Sure enough, he found records of Domain Fusion among the many texts. However, they were not classified as techniques. Instead, they were preserved as the accumulated experience of past practitioners.

These records came from generations of trial and refinement. Over time, they built up a large number of Domain combinations that could, in theory, be fused. For example, Lu Changsheng came across a fusion known as the Wind Sand Domain, formed from the Wind Domain and the Sand Domain.

The Wind Domain itself came from the martial artist's personal comprehension of wind. In fact, not every Domain related to wind counted as a true Wind Domain. Each carried a unique imprint from its creator. Unless they were exactly identical, the Domains could still not be fused.

Even if someone followed these methods step by step, comprehended the correct Intent, evolved the Domains, and brought them to Perfection, fusion could still fail. Hence, these records existed only as records of experience. They could guide, but they could not be treated as fixed techniques. Their results could not be guaranteed or replicated consistently.

I see... Domains comprehended by those predecessors can be fused into new ones. But even if their insights are recorded, no one else can recreate them exactly. There are countless variations for the Wind Domains. Everyone perceives wind differently, just like no two leaves are ever the same. Domains are the same. No two can be exactly alike. At best, what they leave behind is just a reference. If I want to fuse them, I'll have to figure it out myself...

Lu Changsheng finally understood. Now, he knew why fused Domains were so rare. Even someone like Long Yun counted as a top genius among Divine Treasury martial artists, but even after so many years of cultivation, the man had only managed to form a single fused Ice Snow Domain. That alone showed how difficult Domain Fusion truly was. At times, it really came down to luck.

"However, there are still some patterns to Domain Fusion. I just have to find them, and it's going to work out."

Lu Changsheng thought it over. He did have a method in mind, but he was not sure if it was a reliable method. Still, he had succeeded once. The method was simple—splitting Domains.

Take the Starry Sky Waterfall Domain as an example. It had originally been a unique Intent he comprehended by accident. Later, he separated it and practiced it apart as the Starry Sky Domain and the Waterfall Domain. After developing them individually, he found that they could fuse again. This gave him a new direction. It was not something he had planned, as the idea had come to him by chance.

"If this works, it might be a shortcut to Domain Fusion!"

A sharp light flashed in Lu Changsheng's eyes. If this worked, he would be opening a new path once again.

He was not unfamiliar with any of this. Back in the Divine Fortification Realm, he had already been called a waymaker for carving out a new direction in Martial Dao. That was then. Now that he had reached the Divine Treasury Realm, he could probably do it again. Of course, it was only an idea for now. Whether it would succeed still required testing.

If I want to split Domains, I first need to evolve them. And to do that, I have to comprehend Intent... so I'll start there. Hmm... And it has to be a complex Intent. The more complex it is, the more it can be broken down into multiple aspects. Once those evolve into Domains, I can fuse them, and the power will skyrocket!

He was inundated by inspiration. The Heart-Calming Pearl truly lived up to its name, and its impact on him was tremendous. His Perception was already exceptional, but comprehending Intent still required inspiration. With the pearl, his heart stayed clear and focused. Ideas came to him with ease, and it felt as if inspiration could arise in him at any moment.

"Complex Intents... and ideally, ones that can work together," Lu Changsheng murmured. Countless ideas collided in his mind. Under the influence of the pearl, inspiration surged even more frequently. New thoughts emerged one after another, almost without end.

But inspiration alone was not enough. A sudden idea could sound promising, but could it actually be put into practice? Well... hardly.

Lu Changsheng considered taking another Dao Comprehension Pill. If he entered a state of epiphany, he could capture something truly useful. With sixty-eight Five Element Beasts in hand, he could exchange them for a large number of pills. He was no longer short on those, anyway.

When he thought of the Five Element Beasts, a flash of insight crossed his mind, and realization struck him instantly.

"Five Elements..."

Lu Changsheng's eyes lit up. He thought of the Five Elements theory, where they could both complement and restrain one another. However, there was another theory that said that those elements could also complement each other. What if he first comprehended a unified Five Elements Intent and then split it apart to practice each aspect before fusing them back together as Domains?

"You know what? I'll give it a try. I'll study the five elemental powers through those spirit beasts; maybe it'll spark some inspiration," Lu Changsheng muttered. Then he moved immediately and released several Five Element Beasts.
