The giant Spiky Turtle was swimming deep into the sea. Han Sen hung onto to creature, using its large body to avoid the scary shockwaves as they went. When he reached an area outside of the effective radius of the shockwaves, he let go of the turtle. He looked over his shoulder and saw many Spiky Turtles swimming deep into the sea around them.
Han Sen was afraid he might have swum too deep. He didn't want to escape from the shockwave, only to become food for the xenogeneics that lurked in the depths of the sea. So, he didn't dive any further.
While Han Sen floated in the sea, he saw a familiar face approach. It was Xius, the Gana.
She was different from the Gana sisters that Han Sen knew. Xius wasn't one of the Gana nobility, and she was strong.
Han Sen frowned, but he did not abandon his place. Going upwards would take him back to where the dual-wielding turtle and the Dragon God fought. Waiting here seemed like his best option.
