In the era of interstellar navigation, mechas are the sharp blade for the survival of civilization, and the dust-covered fragments of ancient history contain the secrets to subvert the galaxy. Ling Yuechuan is an ordinary researcher at the Federal Mecha Research Institute. During an unexpected archaeological exploration, he discovered a mecha core engraved with ancient characters in the ruins of an ancient civilization buried deep in interstellar dust. Those symbols from the ancient earth can actually resonate with the energy system of the interstellar mecha, unlocking ancient technologies banned by the Federation. When the ancient history that has been silent for thousands of years intersects with the smoke of interstellar war, he has to control a mecha that incorporates the wisdom of ancient civilization. Amid the suspicion of the Federation, the covetousness of interstellar pirates, and the prying eyes of alien civilizations, he gradually uncovers the secret relationship between ancient history and interstellar civilization. Using the mecha as a boat, he searches for the answer to the survival of civilization in the gap between the galaxy and ancient history.
