Chapter 136: Very Reasonable

"Are you sure it's the perpetrator's bloodstain?" Hou Xiaoyong had already taken off his gloves and taken out his phone.

The captain wasn't worth waking up for something like the order of scene investigation, but if the perpetrator's blood was found and the captain wasn't notified, then he could just wait to be chewed out.

Jiang Yuan glanced sideways at Hou Xiaoyong and downgraded him again.

For a scene investigation technician to say something so unprofessional—calling him lv0.8 was really overestimating him; it was unfair to the other technicians in Longli County.

He, Jiang Yuan, wasn't like those vampire forensic doctors who could lick a bloodstain and read out the perpetrator's ID number, blood type, hobbies, and sexual orientation...

In fact, even vampire forensic doctors couldn't do that, because Europeans don't have ID numbers.

Jiang Yuan stated frankly:

"I can only say that this bloodstain is quite special. There is a high probability that it is the blood of the perpetrator or an eyewitness, but it could also be the blood of the victim, Zhang Hong. Let's do a DNA test and then we'll see. Bloodstain DNA should be fast."

Ordinary DNA might take several hours to produce results, but using bloodstains and scabs for DNA allows for direct amplification, and results can be out in three or four hours.

Hou Xiaoyong, the lv0.6 scene investigation technician, slapped his forehead, said "That makes sense," and hurriedly called the captain.

"Let's continue." Jiang Yuan had no interest in the Longli County criminal police captain.

He was just a "big beast of burden" borrowed from the neighboring county; he hadn't eaten any fine forage, nor had he been massaged with music playing, so he would just do what a big beast of burden should do.

Currying favor with the production team leader wasn't something a big beast of burden needed to do.

Of course, the local big beasts of burden in Longli County still cared very much about the production team leader; they became excited and actively participated in the work.

"We'll scan this side now." Jiang Yuan continued to operate according to the method of reconstructing the scene.

A single bloodstain was still not very safe. Moreover, theoretically speaking, the probability of having one bloodstain and then another perpetrator's bloodstain was relatively high—Jiang Yuan believed in his heart that what they had just found should be the perpetrator's bloodstain.

There were no signs of a third person at the scene, so a bloodstain that wasn't the victim's was naturally very likely to be the perpetrator's.

As for where the perpetrator's bloodstain came from, Jiang Yuan first guessed that it was very likely the perpetrator started using their own fists.

Using one's own limbs to strike the other party was a more venting way of expression compared to using a weapon.

It just hurt the hands a bit.

Fists that don't break in movies belong to handsome guys; for those who aren't handsome, hitting people easily breaks the skin on the hands.

Fists are harder than cheeks, but that refers to the hand bones, not the skin of the hands.

Jiang Yuan watched wave after wave and made records wave after wave.

At this time, the technicians from Longli County started to become dissatisfied.

Hou Xiaoyong, who had been elected by the masses, suggested: "Wu Wu Fa Yi Jiang, since we've now discovered another person's bloodstain, shouldn't the subsequent examination be a bit more meticulous?"

"Okay." Jiang Yuan agreed.

Then, picking up another piece of an object, Jiang Yuan still made records quickly and waved his hand to start the next batch.

Hou Xiaoyong reminded: "Should we take another look?"

"Look at... what?" Jiang Yuan asked Hou Xiaoyong in return.

Hou Xiaoyong said cautiously: "I was just thinking... personally, wouldn't the probability of discovery be higher if we looked for a longer time?"

"That thought isn't wrong." Jiang Yuan looked deeply at this lv0.5 scene investigation technician and said: "In that case, come with me."

Hou Xiaoyong looked behind him; the several technicians who had just instigated him all turned their heads away.

Hou Xiaoyong cursed "unreliable" under his breath and could only follow Jiang Yuan to the pile of objects that had just been uncovered.

"What can we see from this cast-off bloodstain?" Jiang Yuan asked Hou Xiaoyong.

Hou Xiaoyong was stunned for a moment and said in a low voice: "Didn't we just talk about this..."

"We just said it might have been caused by a blunt object, right?" Jiang Yuan guided him patiently.

Hou Xiaoyong nodded.

Jiang Yuan added: "Besides being caused by a blunt object, is there anything else?"

Hou Xiaoyong didn't answer, and Jiang Yuan waited patiently for Hou Xiaoyong.

Being a big beast of burden for the production team, it wasn't bad to be able to rest for a while.

Hou Xiaoyong wanted to wait for the captain to come over and see them working hard, so he could only rack his brains and say: "It can also show the force."

"Anything else?" Jiang Yuan asked with a smile.

"This... I don't remember very well."

"It can determine left or right." Jiang Yuan said softly.

"Right, right, right, so this perpetrator is right-handed." Hou Xiaoyong nodded repeatedly, even saying a professional term, and let out a sigh of relief.

"En, continue to look at the morphology of these bloodstains; what can you see?" Jiang Yuan, however, was relentless.

Hou Xiaoyong was stunned again, like a computer that had crashed.

What could he see? Everything he could see had been returned to his teachers. Did he have to ask more?

Jiang Yuan then explained to him in detail:

"First, you pay attention to the size of the blood, because blood of different weights travels different distances when cast off..."

"Secondly, the reason I pay special attention to cast-off bloodstains is that it's easy for the perpetrator's bloodstains to appear within them. Think about why?"

"En, it's because the perpetrator's hand is bleeding, and when they move, it's easier to form cast-off blood. This is also the reason I asked you to pay attention to the morphology..."

Under Jiang Yuan's narration, Hou Xiaoyong's eyes gradually began to glaze over.

He had never been a good student who was good at learning, let alone the fact that this time, Jiang Yuan had outputted so much in one breath... it was too much.

Finally, Jiang Yuan paused slightly, picked up some water, and moistened his throat.

Then, Jiang Yuan looked at the nautilus in his hand and said: "Looking at this bloodstain for so long, it should be considered meticulous, right?"

"Meticulous, meticulous." Hou Xiaoyong nodded hurriedly, then moved his feet, walking while saying: "I'll go see if the captain has arrived..."

He finally understood that he had said the wrong thing just now and had been outputted by Wu Wu Fa Yi Jiang, so he could only passively accept it.

Yet he couldn't beat Jiang Yuan, so he could only endure it.

Compared to being praised by the captain, studying was far too terrifying. Forget it.

The sky was slightly bright.

Hou Lejia, the criminal police captain of Longli County, had just arrived.

"Sorry, sorry." Hou Lejia didn't enter the crime scene; he just shook hands with Jiang Yuan multiple times outside and then exchanged cordial greetings.

Jiang Yuan's hand was gently squeezed and shaken, not too hard or too soft, so he just took it as exercising his wrist.

The polite part ended.

Hou Lejia added: "The bloodstains that Wu Wu Fa Yi Jiang... should be called last night, have already been sent to Qinghe City on an expedited basis. I estimate there will be news soon. Shall we eat something first and wait for the results?"

"Good." Jiang Yuan wasn't one to stand on ceremony.

Although the crime scene hadn't been completely processed, the scene was too large, and with the current manpower, it would be impossible to finish in a week.

Police personnel still had to live.

Hou Lejia and the others actually understood this. Before, they just didn't feel bad about using a big beast of burden from someone else's house. Now that they discovered Jiang Yuan was surprisingly easy to use, Hou Lejia transcended from his initial narrow-minded thinking of using him up all at once.

"Have that boss send over a few portions of pork intestine, pork stomach, and chicken." Hou Lejia called Hou Xiaoyong over and arranged it carefully.

Hou Xiaoyong accepted the order and left, full of confidence. Everyone is confident when doing what they are good at.

The pork intestine, pork stomach, and chicken were delivered in a clay pot, still steaming hot.

The boss seemed to know how to do things; he rode an electric tricycle himself, bringing folding tables and chairs, chopsticks, spoons, and the like.

On the side of the street, dozens of meters away from the courtyard, and seven or eight meters away from another fried rice food truck, several people set up the tables and chairs, placed the clay pot of pork intestine, pork stomach, and chicken in the center, and put the dipping sauce for it all around.

Pork stomach and chicken was already a famous dish; the pork stomach soup was extremely fresh, and the chicken soup was also fresh. Sprinkling a large amount of black pepper on it both balanced the flavor and brought a super fragrant spicy taste. Facing any single dish alone, it could be said to be quite a contender.

And as for eating pork stomach and chicken as a dish alone, if there was any shortcoming, it was that the texture was slightly inferior.

From pork stomach and chicken to pork intestine, pork stomach, and chicken, this flaw was instantly alleviated.

The lid was lifted.

A rich, fresh aroma wafted out.

Several people felt their stomachs growling.

Everyone took off their police uniforms from their upper bodies, their lower bodies in shiny police trousers, and sat around the clay pot.

Hou Lejia raised a cup of tea and smiled: "The conditions are simple today. I'll use tea instead of wine to thank Wu Wu Fa Yi Jiang Yuan..."

Jiang Yuan stood up to raise his cup, drank a little in cooperation, and then buried his head in eating, really like a dull technical person.

"Sword Coming"

Jiang Yuan understood in his heart that his master, Wu Jun, had only mixed a few cafeteria meals with the city bureau's forensic doctors, so he shouldn't think too much and just get the job done.

Hou Lejia, however, showed his smooth side, laughing and building relationships, saying how good his relationship with "Huang the Crocodile" was, telling a few interesting stories between the two counties, and then thanking Jiang Yuan for coming to help, and so on.

It was fortunate there was no wine on the table; otherwise, Hou Lejia could have sweet-talked Jiang Yuan into a daze.

After Jiang Yuan was full, he simply brought up the case and asked: "Captain Hou, I estimate I can finish the bloodstains here in a while. After a rest, I want to go do an autopsy with my master."

Hou Lejia was a bit surprised: "Can you finish so quickly?"

"The DNA on the objects will probably take a week or two to wipe, but I don't think it's of much significance." Jiang Yuan answered very directly.

Hou Lejia heard this and understood; this was a typical case of picking and choosing work. If this were his own technician...

Oh, this wasn't his own technician.

Hou Lejia pondered for a few seconds and felt it wasn't a bad thing. Regardless, the person had found a unique blood scab.

Hou Lejia changed his angle and said: "The autopsy should be finished, there's no situation, so that's why we need to focus on breaking through from the scene side..."

"I'll take a look at the autopsy situation first, and I still need to report to my master." Jiang Yuan was eating pork intestine and didn't even lift his head.

Everyone present understood Jiang Yuan's meaning: If you try to command blindly, I won't do it.

Hou Xiaoyong shifted his butt again and suddenly felt a little happy. The captain had also been rebuffed; being rebuffed himself now seemed very reasonable and very normal.

Hou Lejia heard the dissatisfaction in Jiang Yuan's words, but suddenly slapped his forehead: "Look at my memory. My brain, thinking about useless things all day long. You came over and haven't done an autopsy with your master yet. I'll arrange it, I'll arrange it right now." ===== CHAPTER 137 =====
