Beneath the Deep Strings: the Pulse of the Earth

I, Lin Shen, am an ordinary general practitioner with a hobby of caving. Until I was in a shaft 300 meters deep in the southwest, using a sonar stethoscope to hear a regular heartbeat coming from the rock every 47 hours. Medicine told me it was an auditory hallucination, geology told me it was impossible. Until that mysterious botanist Ye Xian came to me and handed me a note left by her mentor before he disappeared: "Don't look for me unless you hear the heartbeat of the earth and see flowers of flesh and blood blooming on the stones." We were forced to join forces and get into the hole where even the GPS would fail. There are no treasures or ancient tombs down there. There are only living relics that constantly revise the definition of our lives. And the first people to come down have become its latest "organs" to grow. Now, that heartbeat is getting faster and faster. It found us.
