The depth of the sea was not too deep, only 300 meters, but for non-Ocean system superpower users, rescuing people at a depth of 300 meters still required a lot of effort.
Xie Shi'en used his space movement ability, making the rescue operation faster.
It wasn't long before the inflatable lifeboat was filled with Black Iron Dwarves, and the Black Iron Dwarves who came up afterwards could only cling to broken planks and float.
Apart from the drowning Black Iron Dwarves, some were also trapped inside the sunken ship.
The ship was indeed at the bottom of the sea, and most areas inside the ship were filled with seawater, but there were still some places with air left.
Additionally, the magic shield released by the Dwarf Wizard among the Black Iron Dwarves was preventing seawater from flooding in, preserving most of the bridge.
The Black Iron Dwarves were also rescuing each other; those who couldn't swim to the surface were dragged to the ship's bridge.
