In order to resist the interstellar invasion, mankind created the ultimate weapon "Jhin" - a heartless god that sealed the remnants of the ancient gods. She was injured in the battle and fell into the sea, but was picked up by the shark Wang Yuan and brought back to the abyss. He told her "The Daughter of the Sea", took her to touch the depleted star core, and taught her what pain and love are. When she learned to resist the Creator and blocked the world-destroying tsunami with her body, Yuan awakened to protect her and turned into blue foam and returned to the ocean forever. She wiped out the invaders with one thought, threw the truth of the earth to mankind, and then sank to the bottom of the sea with eternal loneliness. From then on, every drop of sea water was him, and every tide was the fairy tale that could never be finished.
