Ze'Chion's Power; Xiao Answers the Summons

The floors beyond that were guarded by the Four Dragon Kings, Besta—one of the Labyrinth Administrators—the Storm Dragon Veldora, and Azhdaha.

Moreover, every floor boss from the Seventy-Second Floor to the Seventy-Ninth Floor was one of the tails of the Nine-Headed Beast, Nine Demon Luo.

After hearing Ramiris's explanation, Rimuru's eyes grew increasingly vacant.

Could it be that the Great Underground Labyrinth's combat strength was, perhaps, possibly greater than that of the entire Demon Country Federation?!

Had the Demon Country Federation unknowingly become this powerful already?!

After deliberating for a moment, Rimuru could hardly just move Adaman to Ze'Chion's floor. If she moved Ze'Chion or Xiao to the Sixtieth Floor, then what difference would there be between this labyrinth and one with only sixty floors?

Rimuru then summoned all the floor bosses in the latter half of the Great Underground Labyrinth, even calling over Xiao from the Ninetieth Floor.

As she looked at Ze'Chion, Yapitto, and the others, all radiating powerful auras, Rimuru's face was filled with unconcealed shock.

You really never knew until you saw it for yourself—Rimuru was utterly stunned.

She had thought Adaman and Alberuth were already monsters through and through, but after seeing Yapitto, Nine Demon Luo, Ze'Chion, and the rest, Rimuru felt she had been far too conservative!

Damn it! These guys were the real monsters!!!

Every single one of them was at the Demon Lord Seed level. They were not newly evolved Demon Lord Seeds, either, but had already reached the limits of that realm. They only lacked an opportunity to advance into Awakened Demon Kings.

Yapitto and Nine Demon Luo were fine. Although the two of them were absurdly powerful, Rimuru could still accept that much.

But, but... tell me, what the hell was this?!

This being radiating dangerous power from head to
