In 1998, the rainy season in Nanzhou was extremely long. A dismembered female body was found in the back hill of Nanzhou University. The deceased was Shen Nianqiu, a graduate student in the Chinese Department, 23 years old. New police officer Chen Mo took over the case, but found that everyone on the campus was silent, the surveillance was damaged, and the investigation was stopped by his superiors as soon as there was progress. Shen Nianqiu said something before his death: "If I don't answer the phone, don't believe anyone else's version." When Chen Mo insisted on pursuing the investigation, a car from the police station crashed into him on a rainy night. He opened old case files and found that another female student's case was solved "accidentally" at the same place ten years ago. The retired detective told him: "Every rainy season, people disappear." The rain is getting heavier. The truth is right in front of you, but the person who reveals it may become the next name to disappear.

A city that has breathed under the water for three thousand years. They are the only ones who can hear its heartbeat. In 1930, on the eve of the Central Plains War. When Zhong Wujiu, an assistant professor at Peking University of Technology, returned home for the funeral of his father who died suddenly, he unexpectedly found a bronze tube deep in his father's ear canal - an artificially implanted device. During his lifetime, my father seemed to be more than just an antique shop owner. He soon discovered that his father left behind an unfinished underground drawing, marking a super project under the Luo River that spanned the Zhou, Han, Wei and Tang Dynasties - the "River Map Array". It is not a mausoleum, but a functioning urban foundation built using acoustics and hydraulics. Once it collapses, the entire Luoyang will be swallowed up. What was even more strange was that Zhong Wujiu began to hear things that ordinary people could not hear: the vibrating sound of metal, the resonance of stone slabs, and the pulse of underground water. And he is not alone. Miners can "see" underground cavities with the sound of hammers, female scholars can knock out the original position of stone slabs in the city, and painters can hear music from thousands of years ago when restoring ancient paintings. They are marginalized people who are troubled by "geophonia", but it is these "defects" that spell out a complete lifeline map of the city. An "inspection team" of American acoustic experts followed closely, coveting this resonance technology. Zhong Wujiu must gather the other six "earth listeners" before the system collapses and the enemy succeeds, to rewrite the city's fate of destruction. --Those who "early listen" listen to the pulse of the earth and bear the weight of civilization.
