After forcibly erasing the old man's imprint from the blade and pouring his immense magic power into it, a scene that slightly changed Qin Fengming's expression appeared before him.
The azure blade merely flashed with azure light a few times before becoming dim once more.
At the same time, the immense magic power Qin Fengming had released suddenly shook and was forcibly repelled by the blade. It seemed the blade's capacity for magic power was limited, as it became instantly filled.

His expression sank. After a brief moment of thought, he waved his hand, and the azure blade transformed into a streak of azure lightning, shooting rapidly toward the hard stone wall before him.
"Poof!" A muffled sound rang out. The three-foot-long blade was like a needle sinking into soft tofu. As azure light flashed, the blade instantly vanished into the wall without a trace.
Only a fine crack slightly over an inch long appeared on the hard stone wall.
