Under the sea, Su Xiao slowly sank, releasing the Boundary Line about 10 meters, with one end connected to the wire wheel on his wrist and the other end wrapped around Speiro's arm.
As Su Xiao descended, Speiro was also dragged down towards the sea by the Boundary Line.
Speiro's eyes rolled back, his body convulsed, and he spat out a large bubble, looking extremely pained.
Su Xiao didn't rashly approach Speiro; Devil Fruit Ability Users become exhausted in seawater. In other words, every Devil Fruit Ability User is essentially a landlubber. No matter how good they are at swimming, once they enter the sea, aside from splashing around, they can't do anything, and without rescue, they'd sink like a stone in less than 10 seconds.
"Hululu..."
Speiro's hand twitched, experiencing extreme pain as seawater entered his windpipe and lungs.
