Their requirements were simple: clarity and accuracy. If they couldn’t produce results, they said nothing, merely accepting it as their own inadequacy.\u003C\u002Fp>\n\u003Cp>Jiang Yuan’s standards were vastly different, because he knew exactly what he was capable of achieving. For fingerprints destined for comparison or database entry, his requirements were naturally far higher.\u003C\u002Fp>\n\u003Cp>But the most crucial point was that Jiang Yuan could provide clear, actionable solutions to obtain crisp fingerprints.\u003C\u002Fp>\n\u003Cp>Several field investigators hadn’t received such “instruction” since leaving school.\u003C\u002Fp>\n\u003Cp>Take ninhydrin, for instance—it should be the most commonly used technique, taught in textbooks and classrooms, and routinely applied at countless crime scenes.\u003C\u002Fp>\n\u003Cp>It’s a chemical reaction with a complex mechanism, but in effect, the ninhydrin method clearly reveals latent fingerprints on light-colored paper, documents, and even wooden surfaces. It’s an excellent, powerful solution.\u003C\u002Fp>\n\u003Cp>Yet in real crime scenes, criminal investigators rarely used this method.\u003C\u002Fp>\n\u003Cp>Without exaggeration, the most common, most frequently used, and often the only method employed in most field investigations was powder development.\u003C\u002Fp>\n\u003Cp>“One brush solves everything” was the daily reality for most criminal investigators.\u003C\u002Fp>\n\u003Cp>And they didn’t even bother switching powder types.\u003C\u002Fp>\n\u003Cp>The technicians on today’s field investigation were all from the Criminal Science Unit. Occasionally, they still used ninhydrin and 502 fuming—but today’s full-scale deployment was why so many technicians were out in the field.\u003C\u002Fp>\n\u003Cp>Normally, for minor cases, responding officers and police station personnel would simply lift fingerprints on-site and enter them into the database, yet many of them had no idea how to use ninhydrin or 502 fuming.\u003C\u002Fp>\n\u003Cp>In fact, due to infrequent use, even the Criminal Science Unit’s technicians weren’t very proficient with ninhydrin or 502 fuming.\u003C\u002Fp>\n\u003Cp>This was easy to understand: if a person walks the same route to work every day and always arrives without issue, why change routes unless some unexpected event blocks the path entirely?\u003C\u002Fp>\n\u003Cp>The technicians of Ningtai County operated exactly this way: if a fingerprint could be lifted with powder, they used powder—no exceptions.\u003C\u002Fp>\n\u003Cp>They didn’t even bother switching powder types.\u003C\u002Fp>\n\u003Cp>Only when dealing with non-smooth surfaces, textiles, or fingerprints that powder simply couldn’t reveal—and only if those prints were critical—would a technician resort to ninhydrin.\u003C\u002Fp>\n\u003Cp>It was like avoiding detours during wind and rain: as long as the road wasn’t washed out or completely blocked, they never changed course.\u003C\u002Fp>\n\u003Cp>Previously, the task of analyzing fingerprints fell to Yan Ge and Wang Zhong; now, it was Jiang Yuan.\u003C\u002Fp>\n\u003Cp>Jiang Yuan was like a company demanding punctual attendance and relentlessly reducing commute time. For field technicians to meet his standard, choosing the right method became vital.\u003C\u002Fp>\n\u003Cp>More importantly, everyone was willing to reduce their “commute time”—or rather, willing to cooperate with Jiang Yuan to improve the quality of database entries.\u003C\u002Fp>\n\u003Cp>In criminal science, this was a martial arts manual: the foundation for survival and self-improvement, a tool to elevate both work and self. Doing work was doing work—most people still preferred to do it well.\u003C\u002Fp>\n\u003Cp>But anything worth doing well always carried some difficulty.\u003C\u002Fp>\n\u003Cp>Take ninhydrin: anyone who’d spent three or four years in police academy could confidently declare, “I know this well.”\u003C\u002Fp>\n\u003Cp>But ask them: “What’s your standard ninhydrin formula?”—eight out of ten would fall silent.\u003C\u002Fp>\n\u003Cp>Only technicians like Wang Zhong, who had actually used ninhydrin, could effortlessly recite: “One gram of ninhydrin and one hundred grams of anhydrous ethanol. We used acetone more often before, but now regulations are stricter—we can’t get much acetone anymore…”\u003C\u002Fp>\n\u003Cp>Jiang Yuan responded without mercy: “Add ether.”\u003C\u002Fp>\n\u003Cp>“Huh? A formula with ether? Add… sixty grams?” Wang Zhong, trying to recall the formula on the spot, clearly didn’t remember clearly.\u003C\u002Fp>\n\u003Cp>Jiang Yuan said: “Use two grams of ninhydrin, then 33.5 grams of anhydrous ethanol, then 66.5 grams of ether. The latent print you’re developing is on a polymeric surface—adding ether will make it dramatically clearer. Your earlier one-to-one-hundred ethanol formula works fine on paper, but it won’t work well on polymeric surfaces.”\u003C\u002Fp>\n\u003Cp>“My mind’s gone blank—I learned this formula before,” Wang Zhong slapped his forehead. He’d studied it, but after years of never using it, the details had vanished.\u003C\u002Fp>\n\u003Cp>Wang Zhong immediately mixed the ninhydrin solution and brushed it onto a kraft paper bag.\u003C\u002Fp>\n\u003Cp>Jiang Yuan opened his mouth slightly but made no further demands.\u003C\u002Fp>\n\u003Cp>Ninhydrin development took one to two hours, but there were ways to speed it up. Still, time was ample, so Jiang Yuan saw no need to nitpick.\u003C\u002Fp>\n\u003Cp>With no further questions, Jiang Yuan selected non-smooth surfaces and began working himself.\u003C\u002Fp>\n\u003Cp>Criminal investigators traditionally assumed fingerprints were found only on smooth surfaces. Or rather, given their skill level, simply clarifying fingerprints on smooth surfaces was already difficult enough.\u003C\u002Fp>\n\u003Cp>Jiang Yuan pulled a glue gun from his field kit.\u003C\u002Fp>\n\u003Cp>He sprinkled powder onto the surface of a vintage LV monogram handbag, raised the glue gun, and sprayed a thick, viscous liquid with a hiss, then heated it with a hairdryer.\u003C\u002Fp>\n\u003Cp>Several nearby field investigators stared, dumbfounded.\u003C\u002Fp>\n\u003Cp>“We have this equipment?” the field investigators wondered, baffled.\u003C\u002Fp>\n\u003Cp>“Found it in storage,” Jiang Yuan said, holding the glue gun and moving around confidently. “Probably bought as a complete set.”\u003C\u002Fp>\n\u003Cp>“Of course—everything’s bundled now…” The field investigators looked helplessly resigned, suddenly realizing they knew nothing about their own department’s inventory.\u003C\u002Fp>",989,"2026-06-20T18:55:00.150Z",1,"Qwen3-Next 80B","778e9e6f97fea1cc13bf9ab9fd9aae08d69a9015a3b66968530e8f6ea29f2793","the-nation-s-forensic-medical-examiner-chapter-80","the-nation-s-forensic-medical-examiner-chapter-78",1000,"https:\u002F\u002Fnovelzhen.com\u002Fimages\u002Fcovers\u002Fthe-nation-s-forensic-medical-examiner-cover.jpg"]
