It was then that Darian had an idea. "Alright. Since that's the case, put 10% of the beast tides under his command. We can test his abilities through that. Even if he betrays us, it shouldn't be that much of an issue."

Only then did all the demon beasts in the hall agree, with one of them voicing their agreement. "That's good, then."

​​

Roan wasn't sad about the end result. If anything, he was satisfied that the demon beasts resolved this issue in such a straightforward manner. If it was the Zasfins, he would probably need to pass through many tests before he was allowed control over anything, let alone 10% of everything.

Phex immediately left after concluding that talk. Phex wanted to bring Roan together straightaway. However, Rean needed his connection with Roan to use his Dark Element. With that said, it was agreed that Roan would meet up with Phex a few days later.

Back at the topic at hand, Rean tried to use his Light Element to help Darian out. "Senior, the blood is mostly produced in the bone marrow. I'll try to use my Light Element to stimulate the marrow so that it can produce more blood. At the same time, I will use my brother's Dark Element to wash the marrows clean of any impurities. Be aware that even though I can protect them with my Light Element, you'll still feel a lot of pain. Dark Element is the opposite of Light. It doesn't stimulate Life Force. Instead, it destroys it. Besides, it's my first time using Dark Element inside the marrow, so it might turn out even worse."

Darian couldn't help but laugh out loud after hearing Rean's warning. "Hahaha! Pain? Little boy, do you have any idea how much pain this old man has been through in his thousands of years of living?" Darian then looked at Rean with a smirk before coolly saying, "Try your best."

Rean tried to hold his laugh as Roan shook his head. Sure enough, this guy had no idea what kind of pain Dark Element was capable of producing. Even the toughest cultivators and demon beasts Roan found in the past didn't last long under such pain. His Dark Element had always been an excellent tool for interrogation.

Rean finally calmed himself as he looked seriously at Darian, saying, "Since senior has said so, then I'll start."

What happened after that would forever be a stain on Darian's pride. Xaon and the other saw the old Black Tortoise crying for the first time. His expression was as ugly as it could be as he couldn't even keep himself standing up. Just ten seconds into the treatment, Rean already had to stop because the old turtle was already weeping.

Xaon quickly came to Darian's side, worried. "Se-Senior Darian! Are you alright? Did he cause you any further damage?"

Darian didn't remember when he had felt so humiliated before. "Shut up! All of you, get out of my palace."

The other demon beasts were taken aback after hearing that. "But..."

"No buts!" Darian exclaimed. "He didn't cause any damage. Get the fuck out!" Darian felt extreme pain, especially since Rean didn't have good control over this method yet. However, he could at least tell that Rean's approach had worked. No real damage was left behind. Unfortunately...it hurt like hell!

Of course, Darian was sending everyone out because he didn't want the others to see his crying face. If the entire treatment went like that, he wasn't the least bit confident that he could control his tears. 'Dark Element is terrifying!'

To be more specific, it was Roan's Dark Element that was terrifying. One must remember that a cultivator or demon beast who had control over Yin Energy could also use it to manipulate Dark Element. However, the Dark Element used by them wasn't even a hundredth as good. Only Roan's Dark Element, which was his natural affinity, could achieve that result.

Somewhat unwilling, all the demon beasts eventually made their way out of the hall.

But before they disappeared, Rean called their attention, telling them, "Wait outside until I'm done here. All of you received injuries from the battle against that so-called Fikin and his group. Don't worry. You only have normal injuries, so it'll be the same as it was with Phex. There will be little to no pain when I heal you."

Xaon and the others nodded after hearing that. In fact, they saw the results when Rean worked on Phex, so they would wait for him nonetheless.

Following that, Rean restarted his work on Darian, who kept screaming. It was quite weird as Darian showed a mix of terror and happiness on his face. Fortunately for him, Rean worked on eliminating impurities first so that the painful part would be over faster. The best way would be for Roan to concoct a pill so that the medicinal properties could help out. Unfortunately, Roan didn't have the necessary skill to make a pill that worked on a Stage Nine Demon Beast, let alone a Divine Demon Beast. The cultivation difference was just too big. That being said, Rean's elimination of impurities was far from what a pill could achieve. In any case, it was still a big help.

Rean finished the washing of Darian's marrows one day later, much to Darian's relief. In the process, Darian kept giving Rean Rank Four Spirit Stones for constant use. Rank Four Spirit Stones were rare, but it wasn't something hard to get for someone at Darian's level.

"Phew... I'm done here. Check your body, Senior Darian. See if you feel any irregularities," Rean said with a satisfied expression.

Darian wasn't crying anymore since he spent up all his tears. Otherwise, he would cry again since the pain was finally over. "It's good, it's good. I can feel it with my Spiritual Sense."

Rean nodded after hearing that. "That's good. Now I'm going to stimulate blood production with Light Element. In any case, you should be able to recover faster with your marrows cleansed of impurities. So, if the Light Element stimulation doesn't work, it won't be as if you got nothing out of it."

Darian nodded and took a deep breath, saying, "Alright, you can start now."

Rean then touched Darian's back after that as his body burst with Spiritual Energy and Light Element.
