• Cheng Tian and Cao Min boarded the ship, and Old Han directed them to check the captain’s quarters for clues.

• Old Han and He Xisong revealed the Waterspout and the Gyarados guarding the Temple of the Sea, including a level 45 Gyarados near Wailord.
• Cao Min identified the Gyarados Horde and Waterspout as the two obstacles, and Cheng Tian proposed provoking the Gyarados while Wailord broke through under Protect.

• Milotic strengthened its Protect with a surge of Water energy, and a terrifying black whale phantom appeared behind it, frightening the Red Gyarados and Old Han's Greninja.
