Chu Mingcheng dove down to the entrance of the cave and firmly held onto the fishing line, preventing it from touching the rocks at the entrance.
Now with a support point, it was not easy for the sea eel to continue escaping deeper into the cave.
When the strengths were equal, it all came down to endurance in a tug of war.
Originally, the sea eel had the advantage, as terrain was on its side, and humans cannot stay underwater for long.
Moreover, the rate of physical exertion when holding one's breath underwater is unprecedentedly fast.
But this sea eel was unlucky, for it encountered a person who was exceptional.
Normally, Chu Mingcheng could move freely underwater for two hours; even if his oxygen consumption increased now, he would still last at least an hour.
Moreover, even if he couldn't outlast it in physical strength, Chu Mingcheng also had life conversion to recover.
Encountering such a person, one could only say it was fate for the sea eel.
