Chapter 91

During this period, Ji Zhixing valued Jian Yi highly, a sentiment shared by Yi Yan, Deng Yi, and others.

"Thanks to you! The experiment has been able to progress so quickly."

"If only I had met you sooner, I could have succeeded in researching photonic chips much earlier."

"You're incredibly skilled at analyzing such a complex model with such precision!"

One after another, words of praise poured from Ji Zhixing's mouth as if they were free, raining down on Jian Yi.

In this research institute, besides Zhu Ren, Deng Yi and Ji Zhixing had known each other the longest. He never knew that Ji Zhixing was so good at providing emotional value to people.

Zhu Ren looked relieved; Ji Zhixing had finally matured after leaving the school.

As a boss, you can be stern, approachable, serious, or even unreasonable. But if you want to save money and get your employees to produce twice the results from one unit of food, you must know how to provide emotional value, making your employees feel that their efforts are worthwhile, recognized, and respected.

Why not make employees happy to do more work, and get a few words of praise for free?

Although Deng Yi found Ji Zhixing a little strange, Jian Yi did indeed deserve the praise.

For example, when Ji Zhixing asked Jian Yi to analyze the DGCNN high-energy particle classification model, he actually thought of using a K-dimensional tree (KDTree) to replace the K-nearest neighbor (KNN) algorithm. This not only solved the problem caused by the different sizes of the nearest neighbor points, but also allowed for sampling of the convolutional network feature map from different angles.

Ji Zhixing asked Jian Yi to find a way to solve the problems of loss of local edge information and spatial information in particle jets. He only took two days to come up with a point cloud representation method in three-dimensional space. By utilizing the disorder and permutation invariance of point clouds, he restored the spatial characteristics of particle jets.

There are too many such examples. Deng Yi sincerely believes that Jian Yi is another person, after his teacher, Ji Zhixing, and Yu Zhuli, who makes him feel that his intelligence has been crushed.

Therefore, it's not entirely incomprehensible that Ji Zhixing values ​​him so much and praises him so frequently, contrary to his usual behavior.

Moreover, Jianyi's brilliance lies in the fact that he can always find suitable mathematical tools to calculate the results that many people can only obtain through exhaustive experimentation. How efficient and how much less equipment is required!

When Deng Yi asked Jian Yi how to cultivate this extraordinary thinking, Ji Zhixing chuckled softly with his back to them.

If Jian Yi could truly calculate it himself, why would he need to go home and "relax" every day? His secret contacts must involve a brilliant mathematician or an entire high-end laboratory assisting him. Geniuses are, after all, unruly and difficult to tame, so the latter is more likely.

Obtaining data through experiments, then working backward to find suitable mathematical tools, isn't particularly difficult. In Jian Yi's case, he found the right mathematical tools solely through his own intellect, and then derived results that were exactly the same as his experiments.

That channel shaped a genius mathematician in this way, an experimental assistant so outstanding that no boss could possibly do without him.

Although Ji Zhixing knew that Jian Yi's identity was unusual, he really couldn't bear to lose such an assistant. Keeping Jian Yi was equivalent to finding an "extra" laboratory for his research institute - the workspace, high-energy particle collider and other instruments, and experimental staff were all free!

Ji Zhixing was having a great time exploiting the data, and kept delaying dealing with Jian Yi, which made Fang Shou a little worried.

"Isn't this too risky? What if our research gets stolen?"

"No." Ji Zhixing was confident that he could dance with wolves like this. "For example, I need the constraint calibration relationship within the new parameter range, but the task I gave Jian Yi is to verify the steady-state combustion plasma physics process, alpha particle fusion, ITER design total fusion power, and so on."

Fang Shou lowered his head in deep thought, his brows furrowed.

Seeing that he still didn't seem to agree, Ji Zhixing was about to tell him again how much experimental time and money Jian Yi had saved him when Fang Shou looked up.

"What...what did you mean by that?"

Ji Zhixing: "Let me give you another example."

He thought for a moment and said, "For example, if I want to develop a special kind of bread, I roughly know that I need several ingredients such as oil, eggs, and flour. Jian Yi is the supplier. Just for oil, I need dozens of kinds of cooking oil such as peanut oil, sunflower oil, olive oil, sesame oil, and soybean oil. Just for eggs, I need more than a dozen kinds of eggs such as chicken eggs, duck eggs, goose eggs, quail eggs, and ostrich eggs. The same goes for other ingredients."

Fang Shou couldn't help but think to himself, "Are you in the grain and oil wholesale business? Oh no, I mean data wholesale."

Ji Zhixing continued, "And most importantly, I have the recipe in my head: which eggs, which oil, what proportions, steps, and temperature to use to make the bread. Do you think Jian Yi could steal my bread recipe just by looking at the delivery slip?"

“That’s definitely not possible.” Fang Shou understood. “So, apart from the kind of eggs and oil you want, the rest are actually unnecessary and should be thrown in the trash, right?”

Ji Zhixing nodded: "That's right."

He felt a little guilty even when he thought of using a dozen pieces of food as an example—it was such a waste! But since it wasn't his equipment or manpower that was being messed with, he figured the waste was fine.

“But…” Fang Shou thought for a moment and then became a little worried, “What if they try them one by one?”

“Exhaustive search? That’s exhausting. Let me calculate…” Ji Zhixing scrolled through his fingers, his mind racing. “Given the unique and vast nature of the experimental data, even if a whole research team tried day and night, it would conservatively take a thousand years.”

Of course, this approach isn't entirely risk-free. But considering the money and time saved, the benefits far outweigh the risks. It's not too late to deal with Jian Yi once he starts "kneading the dough."

Ji Zhixing made no attempt to hide his high regard for Jian Yi. While Jian Yi appeared reserved, she felt increasingly smug.

Deng Yi and Yu Zhuli were once both students at Yan University and had even worked together for a period in the photonic chip project. Although he admired Jian Yi's abilities, he was more emotionally inclined towards Yu Zhuli. He was somewhat worried about Yu Zhuli; after taking two weeks of leave, Yu Zhuli had taken another two weeks, and he wondered if it would be extended further. When he returned, would there still be a place for him in their team?

...

get off work.

Chien Yi lives in Dongsheng Community, 6 kilometers away from the research institute. As a PhD graduate of only 6 years, she obviously can't afford to buy a house, so she rents this house.

He took out his keys, opened the door, glanced disdainfully at the cheap sofa and coffee table in the living room, and turned to walk into the bedroom. He had specially decorated the bedroom; it was stylish and, moreover, very safe.

He walked to the table beside the bed and scanned all the corners of the table with his eyes.

The strand of hair caught under the mouse was still in its original position, there were no fresh fingerprints on the keyboard covered in a thin layer of dust, and the sensors embedded in the monitor were glowing red as they were charging... Everything was normal.

He pressed and released the power strip button on the table, repeating this several times before finally crouching down and reaching under the table to fumble for the switch. The computer screen lit up, the desktop a classic Windows blue. Jian Yi entered a 13-digit password, the computer shut down and restarted, this time the desktop turned green.

He then pulled a USB key from the pillowcase, plugged it into the host, entered the password, and waited for ten minutes before a dialog box popped up.

Jian Yi started typing: "Calculate the multiplicity distribution and transverse momentum distribution of the final-state particles in the jet, as well as the velocity and pseudovelocity of the final-state charged particles. (model.zip)"

A dozen minutes later, the other side must have finished reviewing the model data and sent over a question.

"Why are the models so messy every day, and sometimes even contradictory? Are you sure you have real data?"

When questioned for the first time, Jian Yi panicked for a moment and quickly explained, "It's absolutely true. I've been in the same workspace as him the whole time. The reason we've been doing so many models lately is because he said he's hit a bottleneck and wants to try all sorts of possibilities."

"You'd better believe it! I'll give you the results in three days."

Thinking of the news she heard today, Jian Yi couldn't help but type urging, "Can you hurry up? I heard Yu might be back in two weeks."

The period of Yu Zhuli's absence was the best opportunity for him to take over, gain Ji Zhixing's trust, and get closer to the core of the research. However, Ji Zhixing still valued Yu Zhuli more, and would mutter to himself from time to time, saying things like, "If Yu Zhuli were here, he would have done this or that already." He had to be more efficient.

The other person's words were extremely impatient: "Do you think this is like ordering pizza! It takes 48 hours to do experiments in shifts, and then we have to work backward from the results to make the whole mathematical process look impeccable. If you were as good as Yu, we wouldn't have to go through all this trouble!"

Jian Yi glared at the screen. "Hmph! Look down on people like that!"

Because his English wasn't very good, the person sent to contact him was Chinese. Ugh! So rude!

Three days later, Ji Zhixing praised Jian Yi for the data he provided and then gave him a new task: "You did a great job. There may be some personnel adjustments in the institute in a while, so don't let me down."

Jian Yi instantly understood Ji Zhixing's implication: this meant he would be formally included in the core group! He was overjoyed and even more eager to complete the new calculation task as soon as possible to increase his importance in Ji Zhixing's eyes.

Having finally made it to the end of the workday, Jian Yi ran off without wasting a minute.

After returning to his dormitory, Ji Zhixing went to the system laboratory as usual to verify the part of the data that Jian Yi had submitted that he needed.

Generally speaking, an experiment is not conducted only once; it is necessary to produce the same result twice or more to eliminate the interference of errors.

Now he does it himself once, and the "external" lab does it once, verifying both in parallel. It's both efficient and cost-effective! Ji Zhixing gave a thumbs up to those "employees" he had never met.

However, an accident still occurred.

It was a morning when Ji Zhixing was inspecting a phase of the underground laboratory project at the construction site when he received a barrage of urgent calls from his director.

"Something's happened at the lab building! Jian Yi is a spy!"

Ji Zhixing was shocked: "Ah! How..." How could it have been exposed so quickly?

Once Jian Yi is exposed, he can no longer use him as if nothing is wrong.

Upon arriving at the laboratory building, Zhu Ren, looking worried, greeted them: "Quick! He's upstairs, get him under control!"

"How did you find out?" Ji Zhixing asked. Jian Yi should have been very cautious.

Zhu Ren said, "He sneaked into your office while you were away, and the eavesdropping device he was carrying triggered the infrared alarm as soon as it was turned on." Zhu Ren was still shaken by the piercing alarm sound. "The alarm was really loud, and Jian Yi was immediately subdued by Fang Shou and Deng Yi."

Ji Zhixing didn't expect Jian Yi to fail at this hurdle. This infrared alarm system was brought over by Professor Gao Xiao through Deng Yi. It was said to be the latest research result of a certain unit, and a set was specially set aside for him. He never thought it would actually come in handy.

Upon going upstairs, they found Jian Yi bound hand and foot and thrown on the ground, with Fang Shou looking somewhat embarrassed and Deng Yi looking indignant beside her.

The incident happened suddenly, and Fang Shou hesitated for a moment, fearing that arresting Jian Yi would jeopardize Ji Zhixing's plans. However, Deng Yi, unaware of the situation, ran wildly upon hearing the alarm and encountered Jian Yi rushing out of the office in a panic. He immediately flew into a rage and pounced on her, giving her a good beating.

At this point, they have no choice but to make the arrest.

Ji Zhixing nodded to Fang Shou, indicating that it was alright. In fact, he had originally planned to expose Jian Yi next week, but he didn't expect Jian Yi to expose him earlier. Moreover, since he intended to use eavesdropping devices, he might have other methods in the future, so he had to be on guard.

Ji Zhixing looked at the tiny listening device, no bigger than a fingernail, and couldn't help but sigh regretfully. His "unofficial" laboratory, his unpaid employees, were gone...

When Jian Yi saw Ji Zhixing arrive, she initially wanted to offer an explanation, but upon seeing the undisguised regret on his face, she immediately realized what was going on.

"You used me!!" Jian Yi looked at Ji Zhixing in disbelief.

Ji Zhixing felt a little uncomfortable under their gaze. He touched his nose and said, "This... how can scientific research exchange be considered exploitation..."
