In the 17th year of the Republic of China, at the mine disaster relief site in northern Anhui, when I, Su Qingyuan, was holding a medicine box to rescue the refugees, I met Shen Yanzhi, who was holding a geological hammer to investigate the mining disaster. In addition to the rock formation data, his exploration diary also contained my unsent love letter. But the shadow of an old mining case struck, and half of the diary he left behind suddenly disappeared. In the past ten years, I have changed from a volunteer to a social worker, taking my diary to trace the truth - every mining site has secret marks he left, pointing to the power and money transactions behind the mining disaster. When I finally found him, he appeared as a "suspect in the mining case." It turns out that his disappearance was to protect me from the murderous intention, but there has been ten years of time and blood-stained evidence between us, and even reunion has become a luxury hope on the edge of a knife.
