CHAPTER 1268: CHAPTER 1195: PRACTICAL ASSIGNMENT

The hot water spout, through a clean non-bent straight flexible pipe, sprayed slightly hot clean water, turning Jiang Yuan’s skin bright red.

Being too tall poses such issues in a fixed-temperature shower room: either adapt or sit down. But considering that the stool might have been stepped on by short-statured people afraid of the cold, the only option was to bend over.

In Jiang Yuan’s mind, images replayed like a revolving lantern of the just acquired physical and chemical analysis (Level 5).

Similar techniques are usually presented as criminal physical and chemical identification at the police academy. Academician Lou clearly wasn’t particularly proficient in this field, providing the most general and comprehensive physical and chemical analysis. The real value of this thing somewhat exceeded expectations, enough to support Jiang Yuan in independently establishing a relevant testing center.

Of course, regarding the monetization of knowledge, physical and chemical analysis might not be as lucrative as cryptography, as computer-related fields have overwhelmingly outpaced other disciplines. However, in terms of applications related to criminal fields, the value of physical and chemical analysis is extremely high, and it could nicely compensate for Jiang Yuan’s shortcomings in the field of criminal science.

Especially since modern people have become increasingly elusive. Forget women committing violent murders—such cases have become fewer—men have become more reluctant to resort to blatantly aggressive acts, preferring the use of thallium or pufferfish toxins instead. In these subtle types of cases, having the support of physical and chemical analysis would undoubtedly make the cases easier to crack.

Jiang Yuan took quite a long shower, came out, used a bit of cologne, and changed into a new set of clothes.

"Senior brother, you look really handsome." Miao Ruixiang, already clean, regained composure from the initial shock of the "mentorship under substitute" situation, followed closely behind Jiang Yuan, throwing in a couple of compliments, then whispered, "Senior brother, don’t you think it makes sense for me to study a bit of biology? Surely, there’s no need to tackle those physical chemistry papers."

"Give it a try, do as much as you can." Jiang Yuan lightly reassured his junior brother, and added, "Bring the test papers over when you have them, and we’ll work on them together."

Miao Ruixiang hesitated: "You’re going to do them too?"

"Yeah. It’s been a while, time to get familiar again." After saying this, Jiang Yuan added, "Help me get in touch with Director Wan, book two hours at the physical and chemical laboratory, I need it."

Director Wan, Wan Baoming, is the director of the Changyang City Criminal Science and Technology Center. The physical and chemical laboratory in Changyang City is of top-tier caliber—more than sufficient practice.

Miao Ruixiang was puzzled, scratching his head as he agreed. He thought after graduation there would be a completely different world awaiting, but he hadn’t expected to find the difference to be this extreme after joining the Ningtai County Criminal Police Team.

...

Physical and Chemical Laboratory.

Upon hearing that it was Jiang Yuan who needed it, Wan Baoming actively coordinated and quickly found a slot for him.

Yu Wenshu also concernedly called over, asking, "Jiang Yuan, if you encounter any problems, feel free to come to me. I am entirely on your side."

He was worried there might be issues with the previous case. To Yu Wenshu, this was expected. After handling so many cases, how could Jiang Yuan not make a single mistake? As the saying goes, "the more you do, the more mistakes you make"; in the detective line of work, even more so. For someone at Yu Wenshu’s level, making mistakes is not frightening; the key is how to handle the aftermath.

Jiang Yuan didn’t understand these things, nor did he catch the underlying meaning of Yu Wenshu’s words, casually responding, "No issues for now. I need to work with Wei Shikan on some questions."

Yu Wenshu’s expression turned a bit more serious: was it time to use Wei Shikan’s background?

Despite this, Yu Wenshu still maintained a stern facade and said, "Jiang Yuan, just remember, for anything at all, you can come to me. I’ll help wherever I can, and even if it’s difficult, I’ll find a way to assist. Don’t shoulder everything alone."

Jiang Yuan sensed something amiss, hesitating slightly as he said, "There’s really no major issue; I mainly want to train Wei Shikan a bit."

"Huh, is that so?" Yu Wenshu said a couple more unsure words, and after ending the call with Jiang Yuan, indulged in thought, eventually dialing Huang Qiangmin’s phone.

At times, even the sly and fierce crocodile is useful.

Jiang Yuan had no idea of the intricacies the old detectives were contemplating. In the physical and chemical laboratory, after getting acquainted with various instruments, he was soon joined by Miao Ruixiang and Wei Shikan.

"Let’s start with the papers." Jiang Yuan didn’t even give them time for small talk, instructing Wang Chuanxing to hand out test papers to the two.

"You can look at books but no checking phones. Chuanxing, you’ll be in charge of invigilation and grading." As Jiang Yuan spoke, he also sat down, picked up a test paper identical to Miao Ruixiang’s, and started reading.

Miao Ruixiang and Wei Shikan exchanged glances, both feeling a bit hopeless.

Wei Shikan, always direct, slumped and said, "Master, why can’t we just directly learn the technology? What’s the use of all these theoretical things, especially after having graduated? Who’s still doing papers? Master Shishu might be okay since he just graduated, but I graduated a while ago, and I never really did much paperwork back in school..."

Jiang Yuan ignored him, putting down the paper to pick up a pen and start writing without pause.

He had his advantages and wasn’t in a position to reprimand Wei Shikan. Now doing the papers, it was to confirm his own capability. However, if Wei Shikan wanted to learn the technology, he’d have to follow his plan.

Simply training a bit and nurturing a Level 2 image investigation specialist was a breeze for Jiang Yuan, but it held no meaning. Anyone willing to work hard, strive, and persist, along with a bit of opportunity—preferably a smidge of talent—and under time and practice, could possibly reach Level 2.

Currently, Jiang Yuan possessed several Level 5 and Level 6 image investigation techniques. To pass on this skill set, fundamental mathematical skills were indispensable.

Wei Shikan was poised to become an excellent technical expert. He was interested in solving cases, could handle the frontline work, and his family background was decent, freeing him from worries. All that remained was mastering mathematics, relatively simpler compared to other challenges.

This was certainly more promising than those who studied for a few years only to aim for management roles or job transfers.

Of course, the probability of Wei Shikan failing to grasp it all was also steep. However, Jiang Yuan would only raise his lower limit, without interest in securing it.

Wei Shikan felt somewhat aggrieved. Watching Jiang Yuan’s nimble penmanship on the test, he couldn’t help but feel discouraged.

Throughout his life, though he had endured more bitter experiences than an icy Americano, Jiang Yuan’s demeanor was rare to encounter. He had to admit, he’d rather...

"Check the answers." Jiang Yuan finished the physical chemistry paper, handing it over to Wang Chuanxing.

Aroused from his doze, Wang Chuanxing looked at the time, surprised, "Already done?"

"Just trying out the paper." Jiang Yuan provided a reason, then picked up a set of math papers and began working.

Wei Shikan tilted slightly, observing Wang Chuanxing marking Jiang Yuan’s test paper with a red pen, checking each correct answer.

When Wei Shikan saw Wang Chuanxing comparing it with the answer sheet, he realized everything corresponded perfectly, all correct.

Suddenly feeling impressed, Wei Shikan found the previous Jiang Yuan quite admirable, urgently imagining how if he did this, or that, or like this, his father wouldn’t shout, "Dragons beget dragons, phoenixes beget phoenixes, and mice spawn tunnel-diggers!" every day, as he used to.

"This one." Jiang Yuan, completing the math paper, casually handed it to Wang Chuanxing.

A single set of papers, done in less than ten minutes—something not even a regular math whiz could achieve.

Just like Shing-Tung Yau remarked, many math problems are more akin to mathematical games, not discussions of mathematical issues.

However, the skills Jiang Yuan acquired from the system were different. Though it might not possess such creative power, nor particularly suitable for academic research, it included everything from mainstream ideas of the discipline to random academic games, omitting nothing.

"Full marks!" Wang Chuanxing, having graded Jiang Yuan’s papers, immediately gave a thumbs up.

"Good. Keep on invigilating." Jiang Yuan was satisfied too, for as the saying goes, "Master math, physics, and chemistry, and fear nothing in the world." Now, with proficiency in all three, he could easily calculate the shadow area of a criminal on paper.

Wei Shikan watched Jiang Yuan tinkering with the lab equipment again, decisively set his mind, and delved into tackling math problems.

Despite having faced more bitter challenges than enduring an iced Americano, Wei Shikan had rarely encountered an attitude like Jiang Yuan’s, and he couldn’t help but feel a slight desire to back out.

Turning to his side, Miao Ruixiang, who had recently graduated and had studied diligently, managed to write a couple of answers. Noticing Wei Shikan’s blank paper, he chuckled, saying, "Shishu, it’s okay, your master allows you to look at the books; you can learn and apply it now. Try solving a few, don’t force it. Math is something you either know or don’t."

Feeling suddenly enlightened, Wei Shikan stood up and said, "Shishu, you’re right!"

With that, he turned to Jiang Yuan, saying decisively, "Master, I’d like to study independently for a few days to brush up on my basics. After that, I’ll return to continue learning!"

With those words, Wei Shikan left the room.

Miao Ruixiang was momentarily stunned, then glanced at Wang Chuanxing, whispering, "Cannot handle it?"

Meanwhile, Wei Shikan grabbed his phone, a determined look on his face, and said, "Mom, I need a tutor for math, someone good at linear algebra."
