One slash.
Two slashes.
Three slashes.
Ye Jian's strongest techniques followed soon after, each more powerful than the last.
Yet the results were exactly the same.
The room remained perfectly unharmed.
Not even a shallow scratch appeared anywhere on the surface.
Ye Jian slowly lowered her sword, her expression filled with disbelief.
"Just what kind of material is this room made out of?!" she exclaimed in shock.
Even defensive treasures rarely possessed such durability.
And yet this entire room appeared to be built from that very same terrifying substance.
A sudden thought flashed through her mind.
Without hesitation, Ye Jian turned away from the room and walked a few steps down the hallway.
She raised her sword again and struck a random corner of the corridor wall with all her strength.
"Ding!"
A sharp metallic sound rang out.
The impact traveled up her arm like a shockwave.
Ye Jian froze.
