Yun Zhao, a freshman in the Department of Atmospheric Science, unexpectedly discovered that the ancient book "Essentials of Qi Min" can communicate with the "spirit of phenology". He combined with climate data to awaken the sleeping incarnation of the twenty-four solar terms - the beginning of spring is full of vitality, and the frost is freezing. In order to combat the "entropy erosion" that erodes nature, Yun Zhao teamed up with Tantai Mingjing, a genius from the Department of Geography, to build a "climate sand table" and turned the phenology records in ancient books into sophisticated tactics: Rain and Grain Rain work together to drop precise rain; Xiaomanzhong cooperates to stimulate golden wheat waves as a shield. There is no invincible individual, only the interlocking synergy of solar terms. In ecological battles with heaven and earth as the chessboard, they promoted the global construction of a "solar ecological tactical alliance" and performed a magnificent poem in which meteorological laws intertwined everything, and the latitude and longitude of heaven and earth protected vitality.
