Arc 16The Great Sea Lung
Yang Yi uncovered and defeated the Fishman Great Sage, then captured a Great Sea Lung Larva and brought it aboard the Nightmare Star. As he struggled with a recurring nightmare, he and Su Na used the Dream-Entering Potion, leaving Su Na stranded in a crystalline landscape and beginning to develop the same disease affecting its inhabitants.
- Yang Yi explored Cook Island with Cui Xiya, discovered it was a Great Sea Lung, and found an inhabited interior where Fishmen carried out a cruel transformation ritual.
- Yang Yi confronted the Fishman Great Sage, Kurich, destroyed the ritual, and pursued him as he regenerated and tried to escape.
- Su Na subdued Kurich with her awakened Witch Form, and Yang Yi found that the Great Sage was an experimental sardine created by the Crimson Witch, Bell.
- Yang Yi and Su Na discovered a Great Sea Lung Larva and recovered supplies from the village chief’s hidden storeroom, while Yang Yi began suffering from dreams that left him seemingly dead as he slept.
- Yang Yi returned to Cook Island, pulled the larva from its chamber during the Great Sea Lung’s violent breathing cycle, and brought the sedated creature aboard the Nightmare Star.
- Yang Yi gained experience from the larva’s processed brain matter, fished up crystal diamond ore, and drank a Constitution-Strengthening Potion that gave him a new ability.
- Yang Yi traded a Great Blasphemer statue for a Book of Pure White, sold brain matter, and agreed to enter his dream with Su Na using the Dream-Entering Potion.
- Su Na entered a white landscape of falling Crystal Particles, found crystalline plants and a transformed human, and developed crystalline disease as she searched the island.
