413 Detective Shirong?

Shirong stood in front of the Fourth Barrier and furrowed his brows.

"Huh… so it took the Immortal Crystal Armament a month to disable just one of the barriers…" Shirong muttered to himself. "No… wait. That's not it, this barrier is stronger than before." He added, after noticing the thickness of the barrier and the complexity of the runes.

'Seems like each layer is different and will take longer for the Immortal Crystal Armament to unravel it.' Shirong thought.

After pensively staring at the barrier for a minute, Shirong shook his head.

"So what if it takes even longer for the Immortal Crystal Armament to unravel the next layer? I got plenty of time!" Shirong said with determination.

"But… there are more places to explore at least." Shirong said while looking to his right and left.
