Back in seclusion Yang Rai went. He went into his small sealed world bead. Though he thought the name was getting a little out of proportion. In this world he was capable of having Emperor Realms. But that was a name change that would likely not matter in the end. Yang Rai began studying the world's fruits while a larger stockpile was developed. He noticed that these fruits contained a literal world within them all flowing at various different rates. The mid rank fruits were marginally faster than the Low rank fruits. However he noticed that none of the fruits were even 10 times faster. This must mean my Artifact at least in terms of energy is comparable to either a peak mid rank fruit of high rank fruit. Perhaps even better than that. I wonder…
He spent 5 years investigating the fruits, nothing extra special was discovered about them. Maybe he needed to see the world tree for himself to comprehend any further mysteries behind them. So he put them away for now. Thinking about it any longer wouldn't give him any benefits. Only wasted time. That is the one thing he can absolutely not stand. So he began raising his glyph ranks again. This time when he raised his rank it took 3 sets of Rank 1 Resources. Nothing else worked. He spent 20 more years doing this. He was burning through resources like nobody's business. Though he is the only person who could have even managed it. He finished ranking them all up to T7 R3. He went through nearly 15 Million sets of rank 1 materials. Had he not sped the world's time up this would not have been so easy to accomplish.
Yang Rai was hopeful that he could manage to synthesize rank 6 Materials. However he was not expecting it to be easy by any means. His abilities were legendary but even still rank 6 resources were quite an amazing thing all on their own. I mustn't think this way or I'll never achieve the peak. I have to do this because I require 9 resources for each seal and I'll have 81.
Yang Rai had the 81 sets of rank 5 resources prepared in a meticulously perfect formation. He took a deep breath and began the art of resource fusion. Right away he could tell this would be quite a lot of effort on his part. The sheer amount of energy was just insane. Keeping it in check was difficult. Yang Rai during this had a breakthrough genius level Idea. He began to use space principles to guide the energy directly to where it needed to go. This change drastically reduced the strain on him. The fusion art started to flow so smoothly that Yang Rai knew this work. Now it only took time to finish.
The days pass and into weeks. A whole month passed but Yang Rai successfully fused the resources into a set of 6th rank. Yang Rai had also taken note from this experience that going above rank 6 might be an incredibly difficult time. It might even be better to focus on making his Artifacts world flow faster so he could have enough time to pull it off. It was after all a legendary feat to be able to make these things so easily.
Yang Rai took the remaining rank 5 materials he had performed the fusion multiple times over and over again. Then Condensed a rank 6 tree. It took 9 sets of rank 6 resources to condense this tree. He was already prepared this time and designated all of the glyphs he would use. He planted the tree in place to see just how drastic of a pull it had. He wasn't surprised this time. He had now seen sufficient levels to distinguish the differences in pull between ranks. The glyphs were planted into the tree. Yang Rai had successfully created a rank 6 tree.
