Hidden Dragon Island was surrounded by mountains. Its coast was covered with dense rapids. Under the surging waves were strange and jagged rocks. The only wharf on the island was to the north, which was located between two steep leeward ranges which extended into the sea. The terrain was pretty precipitous.
The waterway entering the wharf was a winding path. The mountains on both sides of the waterway were covered with karst caves of different sizes which were formed due to weathering, water erosion or special geological composition. Half of the karst caves were immersed in seawater. As a response to the crashing of the waves, weird and chilling noises drifted from the inside of the karst caves like the growls of monsters.
Not until the passenger liner moved forward in the narrow and twisting waterway for about 500-600m did Zhang Tie see a large space and caught sight of the 100m long small wharf and some buildings on Hidden Dragon Island.
