When Zhou Yu, a modern astronomy enthusiast, was observing the Leonid meteor shower, he was drawn into the vortex of time and space by the strong light, and exchanged bodies with the female official of the Heavenly Prison of the Yuan Dynasty, Zha Layi'er Yue'e. In modern times, Yue'e relied on her superb astrological skills to accurately predict the fall of meteorites, causing a sensation in the astronomical world overnight. In the Yuan Dynasty, Zhou Yu used modern astronomical knowledge to correct the fallacies of the Qintianjian calendar, and unexpectedly discovered the conspiracy of powerful officials to use the "revelation of the Immortal Heaven" to plot rebellion. The two gradually discovered that the "Revelations from the Heaven of Immortality" that Kublai Khan was searching for were actually astrological signals left by aliens. The "Astrological Records" secretly stored in the Qintian Prison even recorded the secrets of alien visitations. Finally, a rare solar eclipse comes and the two souls return. Yue'e hid the "Star Record" under the White Tower of Dadu. After Zhou Yu returned to his throne, he wrote down this adventure, but it was regarded as a fantasy novel by the world.
