When the longsword collided with the Kylin Phantom, a stifling sound suddenly erupted from within Fall Demon Cliff.
Fang Lin stood right at the edge of the cliff, bearing the brunt of it, and felt an invisible force assaulting his mind, causing his form to waver unsteadily for a moment.
"Not good!" Fang Lin immediately sensed something ominous, as the sound coming from below Fall Demon Cliff had such a profound impact on him.
Boom!!!
The intense conflict erupted, the Kylin Phantom dimmed, and the longsword was sent flying back into the hands of the man in green.
"What is this sound?" The man in green also heard the noise from beneath Fall Demon Cliff, a sense of irritation involuntarily rising within his heart.
Both men, as if by unspoken agreement, refrained from striking again, seemingly wary of the entity lurking below the Fall Demon Cliff.
