Gratitude to Mokumokuren, Eyes Covering the Ground! The Strange Promotion Battle at the Labyrinth's Deepest Point!

"Wait."

Just before stepping into the shadow cast by the cave, Uesugi Tetsu suddenly stopped.

He took Yongming's Headlamp from his storage pack and handed it to Tamamo, who was still wearing the yellow little safety helmet in the middle of the group.

"Tamamo, put this on."

There couldn't possibly be light sources all the time in the depths of the cave. Even flames maintained by Onmyōjutsu risked suddenly going out.

A headlamp that could illuminate hidden demons and remain lit indefinitely was undoubtedly an excellent tool for exploring the labyrinth.

Tamamo acknowledged him, stuffed the two black bricks she had been holding into her pockets, then skillfully put the headlamp on her head and checked the straps several more times to make sure they were secure.

At the same time, Uesugi Tetsu silently transformed into a Four-tailed Fox incarnation.

Then, without anyone noticing, he avoided them and unfolded the Mirage domain.

Mokumokuren could make people hallucinate and alter their perceptions, using that as a fulcrum to disturb their minds and even drive them insane.

As a talent of the same kind, Mirage would certainly have a considerable suppressive and weakening effect on it.

After stabilizing the Mirage domain, Uesugi Tetsu did not put on the enhanced Brahma Mask around his waist. If he could still rely on the Jade Heart Art and Spirit Accumulation Technique to blend into the team for now—

once the Brahma Mask appeared, he would undoubtedly expose his abnormality to an unknown number of Mokumokuren.

Most things in the labyrinth were unknown. Uesugi Tetsu was in no hurry to reveal too many of his trump cards.

Yagyū Shion turned his head doubtfully. He felt that something inexplicable had changed around them, but he couldn't say exactly what it was.

He glanced at Uesugi Tetsu again.
