Under the churning dark purple thunderclouds, towering waves as high as a hundred meters are like crystals

Under the churning dark purple thunderclouds, a hundred meter high wave rises like a crystal mountain range, with its tip condensed into a vortex resembling an ice cone. A 19th century wooden exploration ship was thrown towards the wave peak, with a 45 degree tilt and a broken mast burning with a faint blue ghost fire. In the depths of Langgu, giant octopus tentacles faintly appear, with glowing ancient civilization runes embedded on their suction cups, forming an energy vortex with golden lightning striking from the clouds. On the deck in close range, the boatswain is using a curved knife inlaid with rubies to cut off the glowing seaweed wrapping around the steering wheel. His pupils reflect the second moon slowly rising on the horizon, with blood red cracks covering its surface.
