Lin Ye, an introverted and taciturn graduate student in the Department of Physics, unexpectedly received a mysterious diary made of frozen soil crystal fiber at the funeral of his mentor Professor Zhou Mingyuan. The diary records mysterious events on the frozen soil of the Far North in 1969, as well as a girl named Ashue. Axue is the last guardian of the ice civilization. She used her life to seal the cracks that were about to awaken, and Professor Zhou Mingyuan was the survivor who was rescued by her.
In order to fulfill his mentor's last wish, Lin Ye took his diary to the Arctic scientific research station "Aurora Station", only to find that the space-time chaos caused by the melting of permafrost was devouring everything. In the process of deciphering the secrets of the diary, he gradually uncovered Ashue's true identity, and also understood Professor Zhou's unfinished waiting and regrets throughout his life.
When the crack opens again and the old tree of memory breaks out of the ground, Lin Ye must use modern science as the key to complete Axue's unfinished protection. He finally stabilized the crack, but forever lost the possibility of "meeting across time and space" with Ashue.
At the edge of the crack, a blue bud miraculously grows. It is the fire of civilization left by Ashue and is also a signal of the arrival of spring. Lin Ye inherited A Xue's will and became the new guardian. He would return to Aurora Station every spring to water the bud with melted snow water.
This is a story about protection and inheritance, as well as a story about regret and hope. On the extremely cold frozen soil, they spent their lives interpreting the gentleness and determination of "when the snow melts, you have to plant flowers."
Concept: The novel uses the science fiction setting of "cracks in the frozen soil" to tell the story of the commitment and watchfulness of two generations of scientific researchers to "Axue", a guardian of different time and space, and expresses the theme of "protection and inheritance". The work is based on Lin Ye's inheritance of the last wish of his mentor Zhou Mingyuan, showing the responsibilities and responsibilities of human beings in the face of unknown civilization and ecological crisis, and emphasizing the value of "not everyone can be remembered, but everyone can be the light of others." In the interweaving of science fiction and emotion, the novel conveys awe for nature, civilization, and life, as well as the eternal yearning for hope and spring.
