Death... and me

Rean immediately took all his Fallen Light Star Fragments out after that. At the same time, Roan also brought out the enormous door made of Life's Nemesis Rock. Each of the two had way more Light and Dark Element material than they needed, but at the very least, they wouldn't risk running out of them during the breakthrough.

Kentucky and Celis were a demon beast and a plant, respectively, so they didn't follow the same cultivation mechanics as the humanoid races. They didn't need catalysts at all. As long as the energy was enough, they could break through.

[Alright, now follow the steps. Unlike body cultivation techniques, you won't refine the materials in your body. Instead, you'll be using them as catalysts for the Elemental Transformation. You need the Light and Dark Elements in the materials you have to strengthen the Light and Dark Elements you'll use. That's why they're called catalysts. They can increase a certain type of reaction without changing it themselves, at least not permanently. In this case, they will make it easier for the Elements to be fused with your bodies.]

[Channel the Divine Origin Energy through the Fallen Light Star Fragments and the Life's Nemesis Rock. Then, absorb it and spread it through your meridians. In your cases, you always need both Dark and Light Element to progress, so you'll need to exchange these elements again. Obviously, you will have to use the catalyzed Elements this time around.]

Rean and Roan nodded in response and followed Sister Orb's instruction. Then again, they already had the entire process memorized. In any case, it was always better to have her telling the steps.

With that, Divine Origin Energy was poured on the Elemental Materials before Rean and Roan gathered the surrounding Light and Dark Elements into them. Thanks to the number of materials they had in their hands, it worked just fine, making it possible to catalyze as much Dark and Light Elements as they needed. That's why they had to have at least a certain amount of those materials. If there wasn't enough, the Elemental Transformation would be too slow, ending in failure before even starting. They needed a constant influx of catalyzed Dark and Light Elements for it to work.

[Good. Once the catalyzed Light and Dark Elements fill all your meridians, let them meld before spreading it through the rest of your bodies. Your dantians are already Light and Dark Element, so they have no need for this transformation. All that will happen to them is that they'll be able to hold much more Divine Energy once the breakthrough is made. The real change will be in your ability to control the Elements because of the change in your bodies. It's not wrong to say that your own bodies would turn into Light and Dark Element materials themselves.]

Kentucky and Celis just looked as the twins worked on their breakthrough. They were already at the door of Stage Eight and only needed Rean and Roan to finish their side. Once that was done, they would immediately break through. 'The cultivation process of humanoid races is so annoying sometimes...'

The Dark and Light Elements then spread through the twins' bodies, ultimately reaching every single corner.

Sister Orb was satisfied to see that. [Very good! Sure enough, the Yin Yang Cultivation Manual is just perfect. No side effects have been found so far. Now then, this is the important part. At the moment, the catalyzed elements are only present in your entire body. You need to use it to transform the body by absorbing those elements into your own cells.]

Hearing that, the twins began to absorb the catalyzed elements, which were present in huge quantities due to the catalysts, into their cells. In the Realm of Gods, they didn't call it cells, though. Instead, the Elemental Transformation Manuals said to absorb the Element into their life essence. However, the end result was the same. It was just that even the Realm of Gods didn't know the concept of what a cell was. It could also be said that it was one of the advantages Rean and Roan had while being on Earth in their previous life. Other cultivation manuals simply couldn't beat the Yin Yang Cultivation Manual.

Eventually, the transformation began to happen. More and more Light and Dark Elements passed through the Fallen Light Star Fragments and Life's Nemesis Rock, entering the twins' bodies. Those two materials were also quickly losing their own elemental properties due to the process. The composition was still the same, though. It's just that Rean and Roan probably wouldn't be able to use them anymore if they failed.

Eventually, every single cell in the twins' body seemed to gain a new component. From one perspective, it looked like some new chromosome or something similar. Fortunately, all the cells accepted that new part as if it was supposed to always be there from the very start. It was exactly that thing that marked the success of their breakthrough into the Elemental Transformation Realm. As soon as the last cell in their bodies gained that new elemental component, the twins' cultivation skyrocketed.

Divine Origin Energy entered their bodies like torrents while the Light and Dark Element materials lost their purpose. They were not needed anymore. At the same time, Celis and Kentucky's cultivation also rose together with the twins.

Finally, a huge burst of Divine Origin Energy came from the four guys at once while their cultivation stabilized at the Initial Stage of the Elemental Transformation Realm, or the Initial Stage Eight.

Rean and Roan then opened their eyes and sighed in relief. Everything went smoothly in the end. Sure enough, they felt no barrier or anything like that.

"You..." Well, they forgot about the guy who saw all of that, though. "All four of you broke through at the same time! How's that even possible?!" Hurio was obviously shocked by what he had just seen.

Rean smiled in response. "Does it matter? The important thing is that we succeeded. By the way, how's your cultivation? You're also in the Peak Stage of the Saint Realm, after all."
