Cliff and Rakahn moved cautiously through the dark tunnel, their footsteps echoing against the rough walls. The flickering torchlight barely illuminated the path ahead, forcing them to proceed with utmost care.
Suddenly, Cliff stopped, straining to listen. A faint but distinct sound resonated: the beating of a heart. It was the same rhythm as before.
Before he could focus on it, the heartbeat abruptly stopped, as if someone had deliberately cut it off. A heavy silence filled the tunnel, broken only by the sound of water dripping from the walls.
Cliff turned to Rakahn, concern etched on his face. "Do you think Kido could deliberately stop his own heartbeat?"
Rakahn pondered before replying. "I don't know his abilities well. But as a master swordsman, he might have learned to control his body with precision."
