A scientific research ship sails to the deep sea to carry out exploration tasks. A teenager on the ship accidentally fishes out a strange-shaped mysterious triangular pyramid from the dark deep sea. This seemingly ordinary ancient pyramid hides traces of a prehistoric civilization 60 million years ago, and can emit mysterious waveforms across time and space, with a shocking unknown power. The teenager and his mentor join hands to try their best to decipher the secret of the pyramid. During the process, they unexpectedly have a dialogue with the guardians of the ancient civilization across time and space. As the deciphering deepens, the secrets sealed for tens of millions of years are slowly revealed—the rise and fall of the four prehistoric countries, the cruel resource plunder, and the thrilling interstellar war are all closely linked to this deep-sea pyramid. A small pyramid connects the civilization fate spanning tens of millions of years, and an ancient puzzle about survival and game is waiting for them to uncover the final answer.
