The asteroid Apophis, known as the God of Destruction, has finally arrived, bringing severe cold and, at the same time, loneliness. This book is the sequel to the previous one "Xue Ying Gusu Shangguan's Diary".

The asteroid Apophis was discovered at the beginning of this century, and it visits Earth every seven years. It will be close once in 2022, come again on April 14, 2029, and come again in 2036. Scholars from various countries began to pay attention to the possibility of Apophis hitting the earth. Some said it was one percent, and some said it was one in 100,000. Although it is smaller than the asteroid that hit the Gulf of Mexico that caused the mass extinction of the dinosaurs tens of millions of years ago, its potential threat to humans is still frightening, so it was named Apophis, the god of destruction in Greek mythology. Years of tracking studies have shown that the probability of it hitting the Earth in 2029 is very low, but several Americans, Norwegians, and Chinese do not believe such calculations, and they are quietly preparing.
