Shen Luo's expression didn't change as he raised his hand. In front of him, a crimson light emerged, emitting a crisp sword hum from the Pure Yang Sword Embryo, which then blasted out a sword light several feet long, darting out like a horse in full gallop.
The path of the sword light left surges of red light ripples. The approaching ghosts were hit by the light, and they immediately shrieked and howled as if they were being scorched by a raging fire. They all tried to dodge in different directions.
However, the alley was too narrow, leaving them very little room to dodge. They huddled together in a chaotic mess, unable to retreat in time.
The crimson sword light pierced through everything, going straight into the alley. As soon as it entered the alley, it immediately twisted and turned, darting back and forth like threading a needle. Within a few breaths of time, it dispersed all the ghosts, leaving behind only a series of muddy traces.
