The red-eyed being immediately gave up on fighting as it hastily rushed back to the chamber it came from. At the same time, it seemed to have used some skill that sealed the Underworld Energy its body was using, preventing itself from leaking any more of the energy. Of course, it was just a stopgap solution. If one looked closer, one would be able to see that the being's body was still breaking apart, albeit at a much slower pace.
Frin and Duran looked at each other and nodded before both of them rushed in the being's direction. With such a golden opportunity right in front of them, they wouldn't let it pass that easily. Of course, the being's retreat gave Frin enough time to recover. That was why he was able to follow the being with Duran after the amount of damage he received.
The red-eyed being arrived back in the chamber as it used its power to assemble all the shattered glass it could see. From the looks of it, the being was already used to doing such a thing. Plus, it activated a formation it had prepared ahead of time, which blocked the chamber from the outside world.
Eventually, a few of the souls that Rean saw floating in the chamber turned into energy that was sent into the glass container that the creature assembled. Only then did the being's body stop breaking apart and slowly recover.
Of course, the being wasn't the least bit happy about that. "Twenty Stage Nine Demon Beast Souls! Twenty! How many years did it take me to get this many? What happened to the core? Why did it suddenly stop sending me Underworld Energy? No one was supposed to enter that place!"
*Boom, boom, boom...*
Suddenly, the being heard the sounds of combat coming from outside. Obviously, it was Duran and Frin trying to break the protection the being put in place. "Hmph! Even if there were thirty experts at your level outside, they still wouldn't be able to break into my chamber."
The being was still fuming in anger, knowing that this was the result of Rean's group. 'Then again, just how did they enter the floor where the core was? It should be impossible for anyone at the Transition Realm or below.' Of course, since the creature only thought about the Transition Realm in his mind, he didn't receive any punishment from the heavens.
Unfortunately, he didn't know about Rean's abilities, eventually thinking to himself, 'Forget it. I need to recover my body first. Otherwise, I'll have nowhere to go anymore.' The being completely ignored the sounds of combat coming from outside as it focused on the Stage Nine Demon Beast Souls floating around it.
Each time one of those souls disappeared, the creature felt pain in his heart, knowing that it shouldn't have been used for this. 'Just how long will it take until I get more of them?' That's the only thing he could think of at the moment.
Outside, Rean and Roan were still on the floor with the World Beast Formation's core. After all, Rean only made a one-way entrance, not the other way around. "Do you think the guys are fine outside?"
Roan nodded, saying, "They should be. From what I could see in that demon's performance, his entire power was coming from this core. The same could be said for those demon beasts outside. At this point, they should have disappeared by now. Frin and Duran shouldn't find it too hard to deal with it unless that demon decides to sacrifice everything to kill them. In other words, that means using his own reserves of Underworld Energy. If I were him, I would have retreated the moment we cut off his supply of Underworld Energy."
Rean was surprised to hear that. "So, you're really going to call that a demon?"
Roan looked at Rean and said, "That's the only thing I can think of anyway. I have never seen one in my past life. I've only heard of them through records. However, he does fit the descriptions. Perhaps the demons that don't exist on the other side of the universe anymore stayed here when the universe was divided in two. Of course, this is just pure speculation."
Rean agreed with Roan on that part, saying in response, "Well, if you think that's the case, then it must be. Let's leave it aside for now, though. We need to head out and check the situation."
Suddenly, Sister Orb's voice echoed in their minds, telling them, "Just head inside the Soul Gem Dimensional Realm and use the Circuitry Teleport Formation."
The twins didn't expect to hear that. "Shouldn't it be blocked at the moment?"
[It only blocks access to it when there's danger. Roan said that the demon retreated while all the other demon beasts linked to this core disappeared. If that really is the case, there shouldn't be any danger left, right?] Sister Orb explained.
Rean and Roan had to admit Sister Orb's reasoning made sense. "That's true." Soon after...
*Vup! Vup!*
Rean and Roan disappeared from the floor with the core, appearing straight inside the Soul Gem Dimensional Realm. At the instant they appeared, Rean could not help but say, "Well, guess it worked."
"That means the system considers the actual situation in the formation building and the outside world to be completely safe," Roan added.
Rean and Roan didn't waste time and immediately stepped on the Circuitry Teleport Formation. Following that, they fed it a few Spirit Stones before ordering Sister Orb to teleport them above. As always, there was no way to choose where one would appear. Nevertheless, the twins simply used enough Spirit Stones to teleport in a specific direction. It wasn't as precise as a real Teleport Formation, but that was enough.
Outside, the twins appeared in mid-air and started to fall straight away. Well, they were both at the Nascent Soul Realm, so such a fall wouldn't even scratch their bodies.
*Bang, bang!*
The twins fell on the floor before looking around, with Rean saying, "I can feel Kentucky. Let's go after him. As for the World Beast Formation, we can head back to the floor with the core once we resolve things outside."
Not too long after, Rean and Roan joined Kentucky, who seemed to be quite exhausted. Only then did they take Celis and the rest to head where Frin and Duran were.
