Chapter 129: Who Has Been Here?

Grey Blade moved through the villa.

All around was deathly still, pitch black, as if his entire figure merged into the darkness.

He made not a single sound.

Grey Blade's eyes swept over every corner of the villa.

Suddenly, he looked in a certain direction, the corners of his mouth curving into a smile.

It was an ordinary wall, seemingly no different, but when he knocked on it, it felt solid.

Yet, Grey Blade did not walk away; instead, he continuously caressed the wall, from top to bottom, from left to right, until he pressed hard on a certain spot.

Clearly seamless, that small section of the wall collapsed inward like a separate brick.

The next moment, accompanied by a faint clicking noise,

the unremarkable wall in front of Grey Blade slowly opened, revealing a deep metallic passageway within.
