Chapter 143.4 : Infiltrating Proxia Empire

（What the………………. heck is this place?　A training field?　Or, an arena?）

It had an arena-like circular structure. With the ceiling fully open, the moonlight shined down on it. The place where Rio was standing at right now was above the audience room. The neatly evened out wide ground spread below him.

（Well, there might be no soldiers guarding this place. There’s no need for me to investigate the inside structure of this place.）

Rio lost interest and was about to turn around and leave when――,

「!!!!! ? 」

Rio, whose senses had been raised to the maximum with spirit arts since the beginning of the infiltration, sensed a faint sign. The next moment, Rio was already moving closer to the source of that sign.

He practically jumped from that place in panic. ――,

「Hou, so you sensed the faint sign that was left when I hid in the dark huh? Excellent! You’re the sole intruder who has managed to come this far within the barrier. My name is Nidol Proxia. The emperor of this empire. Welcome to my castle, O insolent intruder.」

Standing there was the self-proclaimed founding emperor of the Proxia empire―― A rock-like man with a bright smile on his face.
