"Are you sure this is the killer's blood?" Hou Xiaoyong had already taken off his gloves and took out his phone.

The captain didn't care about the order of the forensic team, but if they found the killer's blood and didn't inform the captain, they would be in trouble.

Jiang Yuan glanced at Hou Xiaoyong and demoted him again.

A forensic technician actually said such unprofessional words. He overestimated him with a level of 0.8. It was unfair to other technicians in Longli County.

Jiang Yuan was not like a vampire forensic expert who could lick a drop of blood and read the killer's ID, blood type, interests, and sexual orientation...

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

Jiang Yuan admitted, "All I can say is that this blood stain is quite special. It is highly likely to be the blood of the killer or a witness, but it could also be the blood of the victim, Zhang Hong. We'll have to do a DNA test. The blood stain DNA should be available soon."

It could take several hours to obtain a regular DNA result, but using blood stains and scabs for DNA amplification could yield results in three to four hours.

Hou Xiaoyong, a level 0.6 forensic technician, slapped his forehead and said, "Got it," before quickly calling the captain.

"Let's continue," Jiang Yuan said, not interested in the captain of the criminal investigation team in Longli County.

He was just a big ox borrowed from the neighboring county, not getting any good food or massages with music. He just had to do what a big ox should do.

It was up to the big ox to please the production team leaders.

Of course, the local big oxen in Longli County cared a lot about the production team leaders. They became enthusiastic and actively participated in the work.

"We'll search this area now," Jiang Yuan continued to operate according to the method of reconstructing the crime scene.

A single blood stain was not reliable enough. Theoretically, if there was one blood stain, the probability of finding another blood stain from the killer was quite high - Jiang Yuan believed that the blood stain they had just found should belong to the killer.

There were no signs of a third person at the scene, so a blood stain that did not belong to the victim was likely to be from the perpetrator.

It can be hard to make great work when its stolen from "p𝑎wread.com".

As for where the perpetrator's blood stain came from, Jiang Yuan first speculated that it was likely from the perpetrator using their own fists.

Using their own body to strike the other person was a more cathartic expression compared to using a weapon.

But it could hurt their hands.

In movies, only handsome guys had unbreakable fists. If you weren't handsome, it was easy to injure your hands when hitting someone.

Fists were harder than cheeks - Jiang Yuan was referring to the bones, not the skin.

Jiang Yuan looked and made notes wave after wave.

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

Hou Xiaoyong, who was elected by the masses, suggested, "Dr. Jiang, since we have found another person's blood stain, should we be more meticulous in the next examination?"

"Okay," Jiang Yuan agreed.

Then, he took another item and quickly made a note before waving his hand to move on to the next batch.

Hou Xiaoyong reminded, "Shouldn't we take another look?"

"What... do you want to see?" Jiang Yuan asked Hou Xiaoyong in return.

Hou Xiaoyong cautiously said, "I was just thinking... personally, I think if we spend more time looking, we might have a higher chance of finding something."

"That's not a bad idea," Jiang Yuan looked deeply at the level 0.5 forensic technician and said, "In that case, come with me."

Hou Xiaoyong looked back and saw that the technicians who had just urged him had turned their heads.

Hou Xiaoyong cursed silently, "Unreliable," and could only follow Jiang Yuan to the item they had just uncovered.

"What can we tell from this cast-off blood stain?" Jiang Yuan asked Hou Xiaoyong.

Hou Xiaoyong was stunned for a moment and whispered, "Didn't we just discuss this..."

"We said it could be caused by a blunt object, right?" Jiang Yuan guided him patiently.

Hou Xiaoyong nodded.

Jiang Yuan continued, "Besides being caused by a blunt object, what else could it be?"

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

Being a big ox in the production team, it was nice to take a break.

Hou Xiaoyong wanted to wait for the captain to come over and see him and the others working hard, so he had to rack his brains and said, "It can also indicate the force used."

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

"I... I don't remember," Hou Xiaoyong said.

"You can determine left or right," Jiang Yuan said softly.

"Yes, that's right. So the perpetrator is right-handed," Hou Xiaoyong nodded repeatedly and even used a professional term, feeling relieved.

"Okay, now what can we tell from the shape of these blood stains?" Jiang Yuan continued to pursue.

Hou Xiaoyong was once again at a loss, like a computer crashing.

What could he tell? He had returned everything he could tell to his teacher. Did he still need to ask?

Jiang Yuan patiently explained to him, "First, pay attention to the size of the blood. Because blood of different weights will have different distances when cast off..."

"Secondly, it's also the reason why I pay special attention to cast-off blood stains. It's easy to find cast-off blood stains from the perpetrator. Think about why."

"Well, it's because the perpetrator's hand was bleeding, and when they moved, it was easier to cast off blood. That's why I asked you to pay attention to the shape..."

Under Jiang Yuan's explanation, Hou Xiaoyong's eyes gradually glazed over.

He had never been a good student in learning, let alone Jiang Yuan's rapid output of so much information... too much.Finally, Jiang Yuan paused for a moment, picked up a glass of water, and moistened his throat.

Then, he looked at the turban shell in his hand and said, "This blood stain has been observed for quite a while, it should be considered meticulous now."

"Meticulous, indeed." Hou Xiaoyong quickly nodded, then moved his feet, saying as he walked, "I'll go see if the captain has arrived yet..."

He finally understood that he had misspoken earlier, and had been lectured by Forensic Jiang, he could only passively accept it.

Unfortunately, he couldn't outsmart Jiang Yuan, he could only endure.

Compared to being praised by the captain, studying was much more terrifying, he thought.

Dawn was breaking.

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

"Sorry for the delay." Hou Lejia didn't enter the crime scene, but stood outside, shaking hands with Jiang Yuan repeatedly, then making polite conversation.

Jiang Yuan's hand was gently squeezed, neither too hard nor too soft, he took it as a wrist exercise.

The pleasantries were over.

Hou Lejia then said, "The blood samples Forensic Jiang collected last night...or should I say this morning, have been urgently sent to Qinghe City. We should hear back soon. How about we grab something to eat while we wait for the results?"

"Sure." Jiang Yuan was not shy.

Although the crime scene had not been completely processed, it was too large. Given the current manpower, it would not be possible to finish in a week.

Police officers, after all, still needed to live.

Hou Lejia and his team understood this. They had initially taken Jiang Yuan for granted, but now they realized how valuable he was, and Hou Lejia had moved beyond his initial narrow-mindedness.

"Have the boss bring over some pork intestine and stomach chicken." Hou Lejia called over Hou Xiaoyong and made careful arrangements.

Hou Xiaoyong accepted the task with full confidence. Everyone is confident when they do what they are good at.

The pork intestine and stomach chicken was served in a clay pot, still steaming hot.

The boss seemed to know how to handle things, personally riding an electric tricycle, bringing folding tables and chairs, chopsticks, and other items.

A few dozen meters away from the yard, across from another food cart, they set up the tables and chairs, placed the clay pot of pork intestine and stomach chicken in the center, and arranged the dipping sauces around it.

Pork intestine and stomach chicken was a famous dish, with the pork stomach providing a rich soup, and the chicken adding its own flavor. Sprinkled with a generous amount of black pepper, it combined a variety of tastes with a spicy aroma. It could hold its own against any other dish.

If there was any shortcoming to the pork intestine and stomach chicken as a standalone dish, it was that the texture was slightly lacking.

But with the addition of pork intestine, this flaw was instantly remedied.

The lid of the pot was lifted.

The rich aroma wafted out.

Everyone's stomachs started to growl.

They took off their police uniforms, their lower halves clad in shiny, oil-slicked police trousers, and gathered around the clay pot.

Hou Lejia picked up a cup of tea and said with a smile, "I apologize for the simple conditions today. I would like to propose a toast to Forensic Jiang Yuan with tea instead of wine..."

Jiang Yuan stood up and raised his cup, taking a sip in response, then he started eating without saying a word, just like a typical technical worker.

"Sword Comes"

Jiang Yuan knew in his heart that his master, Wu Jun, had only had a few meals in the cafeteria with the city bureau's forensic team. He shouldn't expect too much, just do his job well.

However, Hou Lejia showed his adept social skills, laughing and building relationships, talking about his good relationship with the "Yellow Crocodile", sharing some interesting stories between the two counties, and thanking Jiang Yuan for his help.

If there had been alcohol on the table, Hou Lejia could have easily gotten Jiang Yuan drunk.

After Jiang Yuan had eaten his fill, he picked up his tools and asked, "Captain Hou, I think I can finish the blood stain analysis soon. After a rest, I would like to go and do the autopsy with my master."

Hou Lejia was a bit surprised, "You can finish so soon?"

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

Hou Lejia understood that this was a typical case of picking and choosing tasks. If it were his own technician...

Oh, this wasn't his own technician.

Hou Lejia pondered for a few seconds, thinking it wasn't a bad thing. After all, Jiang Yuan had found a unique blood clot.

Hou Lejia changed his perspective and said, "The autopsy should be done by now, there was nothing unusual, so we need to focus on breaking through from the crime scene..."

"I'll check the autopsy results first, and report to my master." Jiang Yuan said, eating his pork intestine without even lifting his head.

Everyone at the table understood Jiang Yuan's meaning: If you want to give pointless orders, I won't do it.

Hou Xiaoyong shifted his buttocks, suddenly feeling a little happy. The captain was also being rebuked, so it seemed reasonable and normal for him to be rebuked.

Hou Lejia heard the dissatisfaction in Jiang Yuan's words, but he slapped his forehead and said, "Look at my memory, I've been thinking about useless things all day. You haven't even done an autopsy with your master yet, I'll arrange it right away."
