After reaching the water's surface, they still needed to queue. The couple in front of them were local residents of the undersea world, but not from the Underwater Imperial Capital. They were from other vassal states of the undersea world. According to them, the spiral slide of the Underwater Imperial Capital was the most fun, as it's the only one that goes directly from the sea surface to the seabed. In the amusement parks of other vassal states, the spiral slide doesn't have such a long route.
Xia Siyuan, curious and engaged in conversation with them for a while, gained a lot more knowledge about the undersea world.
On the surface was a super luxury cruise ship. Even if other boats passed by on the sea, they probably wouldn't guess the cruise ship's purpose, as it's solely for tourists to ride the spiral slide from the sea surface.
Xia Siyuan and Lin Hanfeng were currently on the cruise, at the very top level, with the blue sea and clouds drifting across the sky.
