The interstellar tunnel has just opened, but it has been dusty for eternity. Xingyuan, an interstellar archaeologist, was trapped in the legend of his family's lost ancient tomb and embarked on his first journey through time. He never expected that at the other end of the tunnel was a tomb palace left behind by an ancient civilization, with the secret history of galaxy migration inscribed in the deep stone walls. Xingyuan is eager to solve the mystery of the demise of his tribe, but on the way to visit the tomb, he encounters the illusion of time and alien mechanisms. Every step of the way approaches his own beliefs and fears. Deep in the tomb, Xingyuan and the tombkeepers of the strange star tribe started a life-and-death battle - to protect the past or to pursue the unknown? When the stars and tombs are intertwined, and fate echoes that of ancestors, Xingyuan must struggle to choose between the truth and sacrifice. The interstellar tunnel is not only a journey through space, but also a confrontation between the soul and history.
