• Diablo watched Ze'Chion and sensed that the insect-type monster had been born to restrain him.

Meanwhile, Nine Demon Luo and her illusion beasts nearly wiped out the Imperial soldiers on the Great Underground Labyrinth’s Seventy-First through Eightieth Floors, revealing her strength to Rimuru, Benimaru, and the others.

• Azhdaha agreed to Xiao’s request, leaving Veldora and Ramiris shocked.

Xiao asked to face the Empire's army, and Azhdaha agreed after reminding Veldora and Ramiris that the Great Underground Labyrinth could revive him.

• Mo Li withdrew his aura after Rimuru gasped that she could not breathe, and Rimuru collapsed across his thigh in her slime form.
• Mo Li told Rimuru that he was angry because Xiao had ignored his instructions and put his life at risk.

Mo Li brought Ramiris, Veldora, and Azhdaha to the control room to question them about removing traps from the Eighty-first through Eighty-ninth Floors.

• Azhdaha realized Xiao was risking his life to grow stronger and prepared to bring him back.
• Mo Li stopped Azhdaha and let Xiao continue because it was his choice.
