The boat gradually approached the sluice bridge, and Komer couldn't help but admire the Jellyfish People's exceptional mimicry skills. Such a floating sluice, driven by telescoping wheels, was quite complicated, not commonly seen in the world of mortals, yet here it was. This type of sluice could effectively prevent enemy vessels from slipping into the Central Water Area after passing through the waterway. It was controlled by operators stationed in the towers on both sides, who were within the surveillance areas of the watchtowers and bunkers, ready to seize control at any moment, demonstrating the Jellyfish People's meticulous and cautious arrangements.
