Chapter 239: The Self-Cultivation of an Undercover Agent

The course lasted until evening; throughout the process, everyone was laughing happily. Usually at seminars and the like arranged by the bureau, everyone just goes through the motions.

But very, very few actually learn anything.

Chen Fan, on the other hand, really taught everyone something.

"For example, when reconstructing a scene, what we use most are fingerprints, footprints, and blood analysis."

"① The convergence area of the bloodstain and its source;

② The type and direction of the force that caused the bloodstain or blood spatter; ③ The mechanism that produced the blood spatter; ④ Helps understand how the blood adhered to the evidentiary item;

⑤ During the blood spatter, the positions of the victim, the criminal, or the wounding object at the scene; ⑥ The possible movement and direction of movement of the victim, the criminal, or the wounding object after the blood spatter; ⑦ Supports or does not support the statements of the accused and/or eyewitnesses; ⑧ Serves as an additional indicator for inferring the time of death; ⑨ Whether it corresponds with other laboratory and pathological examination results."

Chen Fan wrote rapidly on the blackboard.

"So what about fingerprints? The angle of force, the strength of force, the direction of force? We all find it tricky, right? This requires someone with a professional physics background to handle."

"Like this, for example, like this."

Chen Fan picked up a stick and began to gesture.

Everyone nodded one after another.

The corridor here had long been packed with people — not just the corridor, even the aisles inside the room were standing-room only.

"Here the footprint, combined with the fingerprint at this spot — I should have been gripping it like this. Let me demonstrate for you."

Chen Fan went inside the room, then pulled on the wall, and after that picked up the stick, charged over, and struck down.

Then he immediately pinned the person to the ground and went at it with the stick.

Old Song rubbed his own head; he now suspected Chen Fan was settling a personal grudge under the guise of official business.

At this point Chen Fan said, "At this moment, there should be some fiber debris on my backside — the resistor would definitely brush against it with their leg — so we just prioritize checking this area."

"I get up, panicked, my hands fall to the ground, I sit on the floor, dazed, reflecting, terrified."

"Then I just ran, and I took the weapon with me — that's the last bit of self-protection I could think of."

Someone directly gave a thumbs-up and said, "Damn, that's brilliant."

Everyone looked at this person. The person in charge stood up and said, "This case was handled on my end. I watched the surveillance — it's identical, completely identical, even the breathing, even the gaze. Chen Fan, your acting seems pretty impressive, doesn't it."

Everyone burst out laughing. Chen Fan said, "Cut the 960-insults, will you."

Huh, how is that even an insult? Everyone was rather puzzled.

Chen Fan continued, "I'm a fresh-faced pretty boy — how could my acting possibly be any good?"

Hahahahaha.

Everyone laughed uproariously.

In the evening, a few bigwigs put together a table of drinks and told Chen Fan he had to have a few tonight.

Chen Fan and Old Song, finding it inconvenient to refuse, agreed.

The cameraman followed along too. In the words of those bigwigs, it didn't matter — film away, we walk upright and sit straight, film whatever you want, what's wrong with eating a bit, are we not even allowed to have a meal?

"Eat without worry — this money is from my bonus, I have my own money."

"Stop bragging, Old Zhang — that's your wife's family that has the money."

"So what? My wife has money, that means I have money."

Everyone laughed. At the dinner table, eating and drinking, they shared the cases they had experienced over the years.

Chen Fan sat to one side listening.

"You guys are livestreaming a variety show, right? Let me tell you an interesting case. Back then — it should be ten years ago — I handled a case. At the time, a person was shot and killed by someone at the market."

Everyone was stunned. Good lord, that case was no small matter.

"Right after it happened, everyone heard the sound, so our side went to investigate. As it turned out, ballistic analysis was useless, and the forensic examiner didn't detect any gunpowder residue either. I looked at the surrounding environment at the time."

"Then I brought out the police dog, using blood and the like as a trail. The police dog actually found something — it was a steel pellet."

Holy shit.

A steel pellet?

Everyone looked at the police officer speaking.

The audience was all stunned.

The officer continued, "Surprising, right? I was surprised too. But I was thinking at the time, what kind of steel pellet? Then, my kid was playing with a slingshot back then, and I noticed the steel pellet was identical. So I went to ask the popcorn vendor next door, and the popcorn side said that yes, one had indeed popped off at the time."

?????

Holy shit.

Everyone felt rather speechless. Actually, the person popping popcorn felt even more speechless — a disaster out of nowhere.

"Is it strange? In the end, this case didn't involve much compensation either, after all, it was an unintentional mishap, and the other party had given advance notice, telling everyone to be careful — but it just happened to occur at that one-in-a-million probability."

Someone here took a sip of wine and said, "Let me tell you something, Chen Fan — help me make a decision."

Chen Fan listened.

"I have a friend…"

Everyone looked at this officer and sighed helplessly.

They knew what it was about.

"He was my informant. When we closed the net at the time, this person wasn't there. The traces left at the scene — there's a lot of fresh blood. I have absolutely no idea what to do now. I've been searching for three years."

Three years.

A full three years.

Chen Fan said, "What do you want me to do?"

"I just want to know — look at this photo — can you give me a lead?"

Chen Fan took the photo. The photo was already fairly old. Chen Fan looked at the fresh blood on the photo and said, "Mm, this area here is a shot to the arm — the person didn't die. Don't worry."

?????

This works too?

Everyone looked at Chen Fan.

"The blood in a human body actually comes in many colors—light red, dark red, vivid red, and so on. Strip out the oxidized components, and given how quickly the officer took the photo, I could tell it was blood from near the arm, not from the internal organs, so the person is fine."

The officer instantly snapped to attention, the listless officer suddenly alert, and said: "Not dead. Then why didn't you contact me for three years?"

Everyone worried it was something else—an informant is, after all, an ordinary person, and an ordinary person can easily fall into crime.

Chen Fan said: "No, don't worry. You can keep pursuing it, or think back over the places before, try hard to remember—he must have been leaving you clues."

The officer looked at the photo and said: "Reason?"

"Just one footprint; the rest of the footprints are meaningless. From this person's footprint I could tell that he had been shot at the time, but he fell to the ground, then crawled back up, and after that, kept walking forward. An injured informant who keeps moving forward—there is only one reason: he discovered something even more important, more important than the case you've been watching."

At the banquet table on site, everyone fell silent. The crowd, who had been about to drink, one after another set down the cups in their hands.

"This case is tracking drug dealers. Recently the same kind of drug has shown up on my end, so we should be able to find this person."

"Something that was used to drug people? That's my specialty—leave it to me. Give me the drug to analyze, and I can work out the environment and origin for you."

????

No, wait—useless knowledge is starting to pile up, why does it feel like my brain is actually growing?

"Are we still eating, then?"

"Pack it up, take it back, and wrap this case up on the spot. Chen Fan is here, we can't waste it. If Chen Fan believes in this person, then we believe too."

Everyone got up at once, got in the car, and headed for the dedicated office.

Someone brought the drug over, and Chen Fan began running the analysis on his end.
