Eyes are a delicious part of an animal, but they are more suited to the locals.
Just as many people in the Northwest find fish eyes disgusting but think cooked sheep eyes are incredibly delicious, in the Southeast, many people find fish eyes to have a unique flavor but find sheep eyes completely unacceptable.
Similarly, there are pig eyes and cow eyes, which are different from fish eyes and sheep eyes. They all have a bursting sensation and taste better when roasted.
Especially cow's eyes, which are four times the size of pig's eyes, are often boiled and then grilled. Moreover, cow's eyes are actually fatter than pig's eyes, and when grilled, they taste similar to Chinese-style fatty pork belly or the strip of fat on the sirloin side of a Western-style steak.
If we were to use the common marketing phrase "This is the most active cut of meat on a cow," then the meat around the cow's eye is indeed the most active cut of meat on a cow—no meat understands movement better than me!
However, the beef eyes grilled by Zhang Limin, or rather, the beef eyes grilled by the chef from Pingzhou that he found, were only so-so in Jiang Yuan's opinion.
Jiang Yuan didn't need to explain anything; he only took a few bites before stopping, which was enough to explain his actions.
Zhang Limin had come to support the front lines with orders from the provincial government. Upon seeing this, he couldn't help but ask, "Is the taste not to your liking?"
Jiang Yuan replied honestly, "Yes. I usually eat my dad's grilled beef eye. I might not be used to the Pingzhou style, but that's okay, it doesn't matter. I usually eat mostly meat and vegetables anyway."
“I didn’t understand.” Zhang Limin slapped his forehead. “I’ve been listening to the stories the chef from Pingzhou told me. Um… could I have my uncle’s phone number? I want to ask him how to roast it and how to season it.”
"This...no need, it's too much trouble for you," Jiang Yuan said apologetically.
"It's alright, it's alright. Whatever we do is the same, as long as we do it well." Zhang Limin said sincerely, "Give me a call, and I'll organize the chefs to learn together."
Jiang Yuan tried to refuse twice, but couldn't get out of it. In the end, he had no choice but to give out his father's phone number amidst Zhang Limin's fiery enthusiasm.
Zhang Limin rushed out.
Jiang Yuan turned around and said to the people at the table, "I'm really sorry..."
"It's nothing, it's the least we can do." The Pingzhou people present waved their hands naturally: "The main problem is that we can't drink during the battle, so he couldn't even do something to show his appreciation. He was so anxious. If you give them something to do, they'll feel at ease."
"Same as alcohol withdrawal syndrome."
"If I had just passed out, I would have been fine, but now there's nothing I can do but get some food or something. And you know what, it's just not quite strong enough."
As they talked, each of them grabbed a piece of rib meat, touched it to each other, and began to chew.

evening.
Similar to previous campaigns, experts who wanted to rest were considered off work, while those who volunteered to work overtime could return to their seats and continue comparing fingerprints.
Meanwhile, the criminal investigation team officers are on high alert, ready to make arrests at any time based on the experts' findings.
Jiang Yuan also returned to his seat.
Even a high-ranking department head like him was grilling cow eyes. Regardless of whether he grilled them himself, at least the bowl containing the cow eyes was brought in by him. As a guest army that wasn't providing free support, Jiang Yuan felt that S should at least compensate him with a few more criminals to make it reasonable.
Taking advantage of the quiet of the night, Jiang Yuan deliberately chose a murder case and began to carefully analyze it.
The fingerprints came from a body found three years ago. The body was already badly decomposed when it was discovered, but the windproof jacket on the body was of good quality, allowing investigators to collect some fingerprints.
Because the deceased had defensive wounds on his upper arm, and the wounds were concentrated on his chest and abdomen, all on the front, and there were traces of blood splattered at close range on his clothes, the forensic doctor in question believed that there was a possibility of entanglement with the murderer. In addition, the identity of the deceased could not be confirmed, which made it more cost-effective to identify the fingerprints on the deceased's body.
Jiang Yuan reviewed the case file and agreed with the conclusions in the forensic report.
Especially the bloodstains at close range, it couldn't have been sprayed on the deceased himself; it could only have been the murderer's knife-wielding hand that got covered in blood and then, while continuing to swing the knife, flicked it back onto the deceased.
The bloodstain also indicates that the murderer and the victim were very close at the time, suggesting that they may have been entangled.
Although the severe decomposition of the body made DNA extraction impossible, the fingerprints on the windproof jacket could indeed have come from the murderer, or at least from the deceased or a close relative.
This provides a good foundation for fingerprint identification. Of course, it's still not as good as the fingerprints used in standard fingerprint tests, but it's still quite good.
Jiang Yuan then pulled back the fingerprint, first tried to label it once, then ran the fingerprint database again, scanning the top 20 candidate fingerprints, and then stopped.
If Jiang Yuan were still at the level of someone participating in a fingerprint competition for the first time, he would only have two options left, both of which would be tedious methods. One is to label the definite feature points as accurately as possible, labeling seven if possible, six if not, or even five.
Next, the database is run using the identified feature points, and the list of candidate fingerprints is expanded to try comparing 50, 80 or even 100 fingerprints to see if there are any with high similarity when comparing them in reverse. Then, the suspects are specifically analyzed and screened.
The second, less sophisticated method, which is the most commonly used, is to repeatedly try to label feature points, and even guess at some vague feature points, to see if any results can be obtained.
Back then, Jiang Yuan only possessed LV3 and LV4 fingerprint identification skills, with his most powerful LV5 skill being image enhancement. Now, fingerprint identification has been integrated and upgraded to LV6, and the newly added image recognition and analysis LV5 is more comprehensive than image enhancement...
So, Jiang Yuan only tried a few times and quickly determined that... this path was blocked.
At the very least, it's an extremely difficult path of probability, and it might take two or three days to squeeze out even a tiny bit of a chance from the brute-force methods.
After a moment's thought, Jiang Yuan took out his phone and called Liu Zhuangshi, saying, "I saw a case and want to collect evidence. Is that possible?"
Liu Zhuangshi, who was already soaking his feet at home, looked up at the dark night outside the window and said, "Great, no problem. Send me the case number, and I'll have the people in the evidence room report in right now."
The evidence room's working hours are relatively fixed; usually, it's a 9-to-5 schedule. But today, Jiang Yuan made a request, so it's not a normal day.
Jiang Yuan pondered for a moment and then said, "I estimate that we will also need to use the criminal investigation laboratory. We need a high-resolution microscope and a physics and chemistry laboratory."
“No problem, I’ll get the criminal investigation team on duty,” Liu Zhuangshi said without a shred of pity.
"See you later," Jiang Yuan said, ending the call.
Liu Zhuangshi's feet were soaking in hot water. He hesitated slightly and began to do some reading comprehension: Jiang Yuan said "see you in a while." Logically, he should have said that he was going to meet the people in the laboratory and the evidence room. However, he might also have implied that I would be there in a while.
Liu Zhuangshi thought about it again: Right, Jiang Yuan is working overtime, and I'm at home soaking my feet and getting ready for bed. If word got out, people would definitely call me inhuman. So, Jiang Yuan actually assumes I should behave like a decent human being?
Sensing Jiang Yuan's deeper meaning, Liu Zhuangshi didn't hesitate any longer. He pulled his foot out of the bucket and called out, "Wife, I have to go to work."
"Now? I think you don't want your hair anymore!" His wife rushed over and slammed a cup of ginseng tea on the table. "Find your own clothes."
"I'll find it myself, I'll find it myself." Liu Zhuangshi quickly picked up the ginseng tea, slurped it down, put on his clothes, and ran outside.
meeting room.
Zhu Huanguang looked at the fingerprints and suddenly saw Jiang Yuan get up to pack his things. He glanced at the time, smiled, stretched, and prepared to chat with him for a bit on the way.
At this moment, two police officers walked in, each carrying a box of evidence, and went directly to Jiang Yuan to report.
Zhu Huanguang was taken aback, but simply stepped forward.
He wasn't the only one who was curious; several people gathered around.
Jiang Yuan didn't try to hide anything. He opened the evidence box on the spot, found the windproof jacket, and said, "I'm going to take out a few more fingerprints."
"Huh? Should we pick it up now? It might be too difficult to pick it up now."
"This material... must be difficult to obtain."
“If fingerprints were taken before, everything that could be damaged has already been damaged.”
The people present were all experts in their respective organizations, so they naturally offered their opinions.
Jiang Yuan nodded slightly and said, "I'm planning to try out some new technologies or something."
"You still have time to research new technologies?" Zhu Huanguang was the first to express his surprise. He often followed the cases Jiang Yuan handled, and putting aside the specific difficulties and the amount of experience required, the sheer number of cases exceeded that of most people. Under such circumstances, where would he find the time to develop new technologies?
Jiang Yuan had no way to explain, nor did he need to. He simply said, "I guess this is some progress made during the investigation. I don't need to take complete fingerprints. My idea is to take several incomplete fingerprints, merge them, and then compare them in the database. Maybe that will lead to some discoveries."
Level 6 fingerprint analysis, plus a temporary +1, becomes Level 7, which is the world's top-level fingerprint analysis method. You tell me, isn't this technology new or not?
