History is as vast and deep as the ocean, filled with unpredictable possibilities. At times it is calm and tranquil, at other times, waves sweep over it. Countless warm currents surge beneath the sea, flowing toward a perhaps predestined faraway place. The civilizations of various ethnic groups move forward in the lightless deep sea. They follow the currents, waiting for encounters they know nothing of.
Only a fish that has traversed through time, falls from the distant sky into the water. It sees the path of the future clearly, struggles forward with all its might, desperately squeezes to the front of the school, and finally becomes a young leader. It searches for new directions, explores new possibilities, and leads the school behind it towards a brand new uncharted path!
