Chapter 3291

Besides Wu Feiyan, the only ones in the Poqinghui who could truly threaten Ye Chen were probably these three great elders.

Once he confirmed the facial features of the three great elders, Ye Chen gained great initiative; he dared not say he would take the offensive, but at least he could avoid them.

Lin Waner also breathed a sigh of relief for Ye Chen; she felt that with the AI model, the Earth Net, and the facial features of Wu Feiyan and the three great elders, Ye Chen's safety was now greatly assured.

Having evaded Wu Feiyan for over three hundred years, her obsession with revenge had grown increasingly faint; if she were to choose, she would prefer Ye Chen and Wu Feiyan to live peacefully without interfering with each other, so she would not have to worry about Ye Chen falling into danger someday.

During the time she had known and interacted with Ye Chen, she had developed a strong reliance on him; setting aside their mutual life-saving experiences, just this feeling of having no secrets and absolute trust was something she had never experienced in her hundreds of years, and the more so, the more she cherished the present.

Thus, while Ye Chen was on the phone with Li Yalin, she spoke up: "Ye Chen brother, if we only grasp the facial features of Wu Feiyan and the three great elders, we might still not be able to rest completely at ease; if they disguise themselves, our early warning system might fail."

Ye Chen said: "This probably cannot be easily solved."

Lin Waner hurriedly said: "Inspector Li, could you let the AI learn how to judge a person's identity through their expression, gait, and habitual posture and small movements? I feel everyone's walking posture and habitual movements, when carefully analyzed, must differ; many can disguise their appearance and alter their features, but it is hard to constantly abandon one's behavioral habits; if the AI could determine whether two people are the same person through their behavioral habits, then Ye Chen brother's safety would be even more assured!"

Li Yalin on the other end of the phone pondered for a moment, then said: "Miss Lin's idea is not impossible to realize; as you said, everyone's behavioral habits are different, and careful analysis can certainly discern them, but we humans are intelligent beings with logical thinking and recognition abilities; this recognition work can be easily done by humans, but the AI would need extensive learning; I can try to train it, and as for how to train, I may need to think it over carefully."

Lin Waner's bright and kind eyes turned up and down, then she immediately said: "Inspector Li, I have an idea I don't know if it's mature; would you like to hear it?"

Li Yalin said: "Miss Lin, please speak."

Lin Waner said: "You can first have technical staff write a program to let the AI analyze surveillance footage from the data center, so that through this footage and the staff in it, it becomes proficient in assigning complete and accurate body outlines to moving human bodies, down to clearly distinguishing the movement trajectory of each finger, then let the AI carefully analyze the movement trajectories of all outlines, based on facial recognition ability, to deepen its understanding of the same person's behavioral habits; once it understands the behavioral habits of everyone in the data center, then let all staff wear masks or cartoon masks while working normally, and let the AI, based on their bodily behavior, match each person individually to see who they are, and check the accuracy rate of its analysis."

Saying this, Lin Waner added: "The initial accuracy rate probably won't be too high; this still requires our technical staff to continuously optimize code and logic, and also optimize the capture methods, striving to raise the success rate above 95%; if it can achieve a 95% correct identification rate in the data center, we will expand the sample, choose a gate at Ou Su City airport, and let it learn the behavioral habits of tens of thousands of people, mixing in one of our people among them, so the AI can find our person from among these tens of thousands, to see what accuracy rate it achieves; if it also reaches above 95%, then basically there is no problem; of course, if we can give it more samples, even better; the more samples it learns from, the richer its accumulated experience, and the more effective the algorithm will be; if it could cultivate fiery eyes and golden pupils, just by glancing at someone's walking back, it could match that person to someone in the database—that would be perfect."

Li Yalin remained silent for a long time, then couldn't help but ask: "Miss Lin, did you study computer science?"

Lin Waner said: "No, I studied archaeology..."

"Archaeology..." Li Yalin clicked his tongue, then sincerely said: "Miss Lin, why don't I recommend you go to the American UCI to study criminology? Their criminology program is the best in the entire United States, and I feel you were born for this field."

Lin Waner, upon hearing Li Yalin mention the school and major, smiled with a hint of deep meaning and said: "Inspector Li, you flatter me; I really don't want to deal every day with all kinds of sinister and cunning criminals; archaeology is still simpler."

Li Yalin said: "Miss Lin not joining the police force is truly a pity; this field lacks people like you the most."

However, he also knew that Lin Waner's identity was mysterious and her background was certainly great, definitely not someone he could persuade, so he stopped discussing this issue further and simply said: "Miss Lin's method just mentioned should be quite reliable; I will now arrange technical staff to earnestly try it; if successful, it will greatly assist global police criminal investigations."

Saying this, Li Yalin added: "However, this demands too much computing power, and the cost is too high; it will likely be difficult to popularize, but our computing power is abundant, so implementing surveillance and early warning for a certain group of people should still pose no problem."

Lin Waner said: "The pace of improvement in computing over these years is such that saying it's like the Big Bang is not an exaggeration; perhaps the computing power issue will be resolved in a few years."

"That makes sense." Li Yalin laughed: "Then I won't worry about my colleagues worldwide; believe it won't be long before they can also receive doubled computing power."

Afterwards, he said: "Miss Lin, Mr. Ye, there's nothing else; I'll seize the time to implement Miss Lin's idea as soon as possible, striving to put it into use at the fastest speed!"

Ye Chen looked at Lin Waner, gave her a thumbs up, then said to Li Yalin: "Okay, Inspector Li, you go ahead with your work; we'll contact you again if we have matters."

After hanging up, Ye Chen couldn't help but ask Lin Waner: "Miss Li, Inspector Li wants to recommend you to study at that university and major; you wouldn't have already studied it long ago, would you?"

Lin Waner has lived so many years, having earned who knows how many degrees; idly studying a criminology major would not be strange.

Lin Waner, upon hearing Ye Chen's question, laughed and said: "I have studied the school, but not the major."

After saying that, Lin Waner specifically explained: "The UCI Inspector Li mentioned is the Irvine campus of the University of California; the predecessor of the University of California was the California College; I was a student in the first cohort of California College, and also the first Chinese student."

Ye Chen nodded with an expression of no surprise, laughing and saying: "I just guessed you must have some connection with this school."

After saying that, Ye Chen asked her: "By the way, which year did you study at that California College?"

Lin Waner thought for a long time, uncertainly said: "It's been a long time; I also don't remember clearly, but it was before the Civil War, because after the Civil War broke out, I left North America."

Saying this, she hesitantly said: "It should be 1854 or 1855..."

Ye Chen couldn't help but cough twice, embarrassedly saying: "Cough cough... I knew this matter would be very ancient, but I didn't expect it to be this ancient..."

Lin Waner laughed: "Young Master may think it's ancient, but even at that time, I was already over two hundred years old, and it was around that time when the United States gradually established many state universities; I was truly bored, so I enrolled in some schools to study a bit; since my appearance has never changed, I dare not study too long at university, only able to finish courses as quickly as possible, then move to another place and find another university, merely treating it as a pastime during my flight."

Saying this, Lin Waner added: "By the way, in this school's historical archives, there is a photo of the first cohort of students and teachers; I am in it, but that photo is too old, its clarity insufficient; I estimate Young Master would not recognize me even if he saw it."

Ye Chen, with curiosity, searched for this university's website; in the historical introduction on the site, he indeed found the photo of the earliest batch of students; a photo from over a hundred years ago had already blurred and yellowed, yet Ye Chen still, among many men dressed in very Western style, found Lin Waner's figure; in the photo, Lin Waner appeared rather petite, and with the overall yellowish tone of the photo, she also seemed to carry a hint of Native American maiden.

Ye Chen could recognize Lin Waner also because she had told him she was there; otherwise, just looking at the photo, he truly could not discern anything.

After carefully examining this group photo, Ye Chen surprisingly asked her: "Did this school have only a few female students in total?"

"Yes." Lin Waner said: "Back then, men and women were still very unequal; women's social status was not high, nor did they receive much attention from their families; those who could attend university were indeed few."

Saying this, Lin Waner leaned in to look, pointing at a middle-aged white man in the photo to Ye Chen and said: "This person was a highly respected professor at the school at that time, and also one of the university's joint founders; but in fact, he was an orphan I adopted and raised in Britain; when I brought him from Britain to North America, my public identity became his adopted daughter; later I went to Japan, and he helped me write a recommendation letter, enabling me to study in Japan."

Ye Chen couldn't help but sigh: "Miss Lin's life is truly rich and colorful."

Lin Waner laughed: "Young Master, you are destined to attain longevity in the future; then you too will be able to feel that rich and colorful life."

Ye Chen shook his head: "Social progress is too fast; later, even if I live forever and never need to hide from Wu Feiyan's pursuit like Miss Lin did back then, at that time I would have to strive to hide from the whole world, imagining Miss Lin back then wandering the world with different identities, integrating into these places' lives—such possibility no longer exists."
