Legend has it that there is a "Guixu Treasure House" hidden under the deep sea, which not only contains a large number of treasures, but also can fulfill a wish of "reunion". In order to find his father who has been missing for many years, diver Jiang Che formed an expedition team and embarked on a journey into the deep sea. Among the companions are a wise and courageous navigator, a scholar proficient in ancient writing, and a mysterious woman Shen Lan with an unknown purpose. During the voyage, they encountered strange ocean whirlpools, legendary deep-sea monsters, and other treasure hunters. What's even more surprising is that Jiang Che discovered that the logbook left by his father was highly consistent with the secrets of Shen Lan's family - Shen Lan's ancestors were the clansmen who guarded the treasure house, and the treasure house's wish to "reunite" required sacrificing the blood of the guardians. When the expedition team finally arrived at Guixu, Jiang Che faced a dilemma: to wake up his father, or to prevent the tragedy of the Shen Lan family from happening again.
