Chương 814: Silverstar Sand

Under Han Li's gaze, the flying dagger struck the stone wall, emitting a blinding white light.

Sensing this, Lu Weiying's expression slightly changed. He waved his hand and immediately withdrew the flying saber.

Han Li focused his gaze and saw that there was a faint knife mark that was about an inch deep where the flying knife had struck. There was a faint silver light emitting from the knife mark.

"This is…" A trace of surprise appeared on the old man's face. He hastily took a few steps forward and carefully examined the saber mark.

After a short moment of observation, the old man's voice began to tremble. "Silverstar Sand? There is a Silverstar Sand mine in this stone wall?"

Hearing the words "Silverstar Sand", Han Li's expression changed drastically. He also walked forward and reached out a finger to gently touch the saber mark, carefully appraising it.
