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 exploration holes in the frozen soil of Northeast China, the Alxa Gobi, the Taihang Mountains fault zone, the folded mountains of western Sichuan, and the karst caves of Yunnan. He drilled into the core of the earth day after day and carefully recorded the stratigraphic data and construction parameters. 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, it suddenly became empty. It 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.
