Nobody mentioned the Black Death Outbreak Technique, the mutant ability he had learned.

He simply took another opportunity to visit the Underground Labyrinth, delving into its seventh layer!

This place was already considered deep within the Underground Labyrinth, well beyond the influence of the military and the Professional Guild.

It was filled with various demon creatures, monsters, Fallen Ones, and even rumored to be inhabited by foreign races.

He did not share what had happened there with anyone but instead kept his lips tightly sealed.

In the following days, other high-level Professionists sought to venture into the seventh layer of the Underground Labyrinth, but what awaited them was a desolate expanse.
