章 416: Chapter 420: Return to the Creeping Shadows

Agatha instantly retracted her hand, looking at her fingertips with an unsettling suspicion.

However, the nun accompanying her, who was closest to her, had already witnessed this strange scene. The nun immediately widened her eyes in surprise, "Gatekeeper, your hand just now..."

Agatha frowned. For the moment, she did not know what was going on. Just then, one of the guardian warriors stepped forward, prudently lifted his combat staff, and knocked on the stone wall, which appeared no different from the surrounding ones.

The staff struck the stone wall, producing a crisp sound, but nothing changed on the wall.

The guardian turned his head, nodded gently at Agatha, then mustered the courage to step forward and touch the stone wall directly with his palm.

Nothing happened; the wall remained a wall.

"It's just a wall," the guardian frowned. "But just now…"

Agatha said nothing, merely stepping forward in silence, reaching out her fingertips toward the wall once more.
