Death... and me

As confused as ever, Roan finally asked again. "So, what will it do?"

Rean then pulled Roan above the formation before he threw a few Spirit Stones into the spaces made for them in the formation. The formation then began to react with the original formation under it while Rean explained, "The World Beast Formation takes blood from demon beasts from over the entire world. Obviously, the blood can't come here by land. The formation below us was part of the series of formations responsible for teleporting the blood once it was dragged from the demon beasts into the ground."

Rean then looked at Roan with a smile as he asked, "So, where do you think the blood will pass first to make the World Beast Formation increase the demon beasts' strength?"

Roan understood what Rean meant, muttering, "Through the core..."

Rean nodded. "Exactly. Thanks to the Spatial Circuitry Formation Runes, I was able to hack into the simpler spatial runes of the formation below us. Now I'm using its teleport destination as the destination of my own. Obviously, it's right inside the level below. The core's level."

As soon as Rean finished talking, the formation finished charging up with his Spirit Stones and flashed with a silver light as Rean and Roan disappeared. In the very next second, the twins reappeared on the floor below.

"Look there!"

Immediately, they found the core of the formation. It was transparent, so it was possible to see inside. Blood of demon beasts passed through it in a flash before more blood arrived right after. Rean and Roan already knew the destination of the blood, the Blood Lake.

However, Roan was the first to notice some symbols on the core's shell that he had never seen before. They shone with Underworld Energy nonstop. Not only that, at the very center of the core, a dark cloud floated. All the demon beast blood passed through it before they were sent to the Blood Lake. However, that dark cloud seemed to be losing strength as time passed. It's just that it was too slow. At that rhythm, it would take at least a few hours before the dark cloud disappeared.

Neither Rean nor Roan needed to think too much to understand that the dark cloud was the Underworld Energy stored by the red-eyed being. "So that's where his energy is coming from. As I thought, coming here was the right choice. I just hope we arrived in time," Roan said as he took his White Star, ready to cut the core to pieces.

However, Rean immediately put a hand in front of him to stop Roan. Obviously, Roan found it strange. To prevent the waste of more time, Roan used his Soul Connection with Rean to ask, 'What is it? Is there some sort of formation trap?'

Rean shook his head as he told Roan, 'No. That guy wouldn't be able to make a formation inside this place even if he wanted to. The balance of energy here is perfect, and any new formation would put everything in disarray.'

'Then, what are those symbols on the core? Aren't they formation runes?'

Rean shook his head, saying, 'I don't know what they are, but they definitely aren't runes. Most likely, they're something from the underworld you talked about. They are full of Underworld Energy as well, aren't they?'

Roan nodded, saying, 'Yes. One more reason for us to destroy it straight away. Frin and Duran won't hold for long if they haven't died already.'

Rean shook his head after that. 'There's no need. Those symbols over the core aren't runes. However, I can tell that they are very fragile, even more fragile than the runes. Just use your Dark Element the same way you did to stop the Underworld Energy from invading your soul. I believe you can destroy them without affecting the core.'

Roan was surprised to hear that. Nevertheless, he immediately nodded and moved to the core. As Rean mentioned, the balance of formations in this place didn't allow for more of them. Because of that, there were no defensive mechanisms in place. Rean believed that was the reason why entering the last level of this building was so hard. If not for the spatial cheat runes of the Circuitry Formations, he was sure they wouldn't get here for a very, very long time.

Roan's hands touched the symbols and immediately felt them invading his body, especially his soul. However, as an ex-Death Spirit, he only snorted in front of that. The first time he fought against it was because he didn't know it was, after all. Now that he knew, even a thousand times more of this energy would be useless if it wasn't used to attack.

In a second, Roan already drove the energy out of his body as his own Dark Element blasted against the symbols. The symbols then began to break apart one by one, eroded by the Dark Element's power. In the end, Dark Element could destroy almost anything.

Outside, Frin and Duran had already reached their limit and knew that they would die anytime soon. The opponent was simply too strong and seemed to have an infinite amount of energy. Kentucky, Gulan, and Red were no better. Celis was definitely the worst one out of them, as his human tree body seemed to have withered a thousand years.

Eventually, the balance broke, and the demon beasts passed by their blockage. Frin and Duran tried to fight them back, but the red-eyed being injured them every time they spent a moment to deal with the demon beasts.

*Bang!*

*Arrghhhh!*

Finally, Frin made a huge mistake and crashed against the ground. The red-eyed being also made sure that Duran wouldn't arrive in time to help Frin either as he already moved to give the final strike...or so he tried.

*Crack, crack, crack...*

Suddenly, the being's body began to literally...break apart! "WHAT?!"

At the same time, it felt its connection with the Underworld Energy it had stored in the core disappear completely. "Impossible!"

That wasn't all. As soon as his body began to break, all the demon beasts around started to contort in pain. It was then that the demon beasts' bodies began to transform into specks of red lights, just like the ones Rean's group had killed so far. Frin, Duran, Kentucky, Celis, and Red looked at that in dismay. Nevertheless, they could guess who made that happen. "What did those twins do this time?"
