As Vaan absorbed the divine energy crystals and circulated them through his body in sync with the system, his refinement speed doubled. At the same time, his energy cultivation quickly soared at a speed that would only make energy cultivators turn green with envy. After all, while the system had shown a gradual process, he did not even stay in the Energy Gathering Realm for three breaths before advancing to the next realm. Due to his already sturdy body, he had practically skipped the first realm of energy cultivation. Nevertheless, it didn't end there. Shortly after entering the Spirit Condensation Realm, his cultivation continued to soar to the next realm with seemingly endless momentum. Within a few minutes, the gate of the Revolving Core Realm was forced open. The accumulated energy in his Lower Dantian had regained its original solid state. Although it seemed like a pointless process since he transformed solid divine energy into gas, only to turn it back into a solid state again, the Revolving Core in his Lower Dantian was completely different from the original divine energy crystal. After all, the Revolving Core completely belonged to him. On the other hand, the divine energy crystal belonged to someone else from the past. Even if it entered his body as it was, he would hardly have any control over it. That was why it had to be broken down and refined. In the process of circulating the divine energy throughout his body, he was wiping out its residual will and replacing it with his own. Only energy with his will was his to control freely. Nevertheless, the divine energy crystal in Vaan's hand was quickly depleted within minutes. All of its divine energy was absorbed, refined, and assimilated with his Revolving Core. Vaan took out the next piece of divine energy crystal from his Heaven-Swallowing Space and continued to cultivate. The middle stage of the Revolving Core Realm... The late stage of the Revolving Core Realm... The peak stage of the Revolving Core Realm... It took an instant to enter the Energy Gathering Realm, several breaths to enter the Spirit Condensation Realm, and several minutes to enter the Revolving Core Realm. However, entering the Heaven Ascension Realm took Vaan more than an hour. Although it was much slower than the earlier realms of energy cultivation, Vaan had no complaints about the speed. After all, according to some of the fragmented memories of his past life, most cultivators from desolate realms would spend at least a decade in the Energy Gathering Realm, two decades in the Spirit Condensation Realm, and half a century in the Revolving Core Realm. As for the Heaven Ascension Realm, many cultivators from these desolate realms would take at least a hundred years to reach it. Of course, the main problem for their slow progress was the scarcity of spirit energy in their desolate realms. However, even in the higher realms, reaching the Heaven Ascension Realm in one hour was very rare. No doubt, Vaan had the system, his powerful bloodline, and overwhelming talents to thank for such an achievement. After reaching the early stage of Heaven Ascension Realm, Vaan ended his cultivation and shifted his attention back to the Everlasting Blood Mantra. Perhaps due to the fragmented memories of his past life, he felt rather familiar with his energy cultivation. Thus, it didn't take him much time and effort to gain complete control of 'This should do...' Vaan thought after several energy circulations. After successfully refining his first origin blood, Vaan had no doubt the Everlasting Blood Mantra was a supplementary technique for energy cultivation. However, Vaan didn't expect the first type of blood essence he drew from the blood bottle to possess a strong ancestral bloodline. He thought the bottle of a hundred different blood essences collected was something Hecate had done casually on short notice. Was that not the case? Or was it just a coincidence? Nevertheless, Vaan didn't look into it too deeply. He continued to cultivate the Everlasting Blood Mantra with the remaining blood essence in the bottle. 'Dark Fae God Bloodline...?' Vaan was surprised.
