Indian Ocean.
Inside a cave on an underwater island northeast of Cocos.
Ye Yuan had just swum past a right-angle bend.
A black shadow shot straight toward him.

And the stabbing pain from his fist.
Told Ye Yuan that he had run into serious trouble.

Some transparent objects clinging to the cave walls.
Retreated one after another when exposed to its light.
Naturally,
