Drilling Work Notes

Thirty-eight-year-old Ye Shen has been working in the field of geological drilling for sixteen years, and he keeps seven heavy work notes in his hand. In the past few years, he has traveled all over the country, drilling reconnaissance drilling in the northeastern permafrost, the Alxa Gobi, the Taihang Mountains fault zone, the folded mountains in western Sichuan, and the karst caves in Yunnan. He drilled into the core of the earth day after day and carefully recorded the stratigraphic data and construction parameters. The secret triangular marks on the edge of the notebook are the unusual and suspicious points he privately noted: sudden drilling speed, strange mud, inexplicable noises at the bottom of the hole, and artificial debris appearing out of thin air in the rock formations. These strange underground things that cannot be written into a formal report have become unsolved mysteries in his heart. The ZK-17 borehole in Daxinganling fourteen years ago has been a long-standing problem for him. When the drill bit reached 132 meters in the frozen soil in winter, the drill bit suddenly became empty and accidentally penetrated the secret underground military base of the Japanese invaders buried deep in the mountains and forests. Concrete fragments and rusted steel bars came out with the mud. The dull and decaying smell of the confined space was still fresh in his memory. For safety reasons, the borehole was finally sealed with grouting, and the truth behind the ground was sealed, leaving only half of the unfinished record in the notebook. Nowadays, the deep investigation site of Qingfengling is stirring up trouble again. The 347-meter-deep granite core shows smooth artificial sections that are impossible to form with natural rocks. The familiar old smell reappears, and the dusty past is reawakened. The book uses handwritten narratives, rejects supernatural stories, and relies on realistic scenes of hard-core geological drilling to connect stratigraphic anomalies in various places over the past sixteen years. An old drill captain opened the dusty notes and explored downwards again, uncovering the history and underground truth buried by time under the mountains and rivers.
