Was Li Yunxiang affected by hallucinations?
Wei Hongbo frowned and thought for a moment, then shook his head. "That's just your speculation. She's already dead; there's simply no way to prove it."
"Don't rush, I haven't finished yet." Wei Hongsi waved his hand, speaking unhurriedly. "Hallucinations are a typical symptom of schizophrenia, but Li Yunxiang's case is very peculiar. I suspect that perhaps there was a consciousness that did not belong to her within her. Her words and actions were influenced by that consciousness, rather than being pure hallucinations."
"Isn't that just multiple personality disorder?" Wei Hongbo asked, somewhat confused.
"No, it's different." Wei Hongsi continued to educate his older brother. "Dissociative Identity Disorder, the so-called multiple personality disorder, is usually related to severe childhood trauma and is accompanied by memory gaps during identity switches.
"But Li Yunxiang's behavior in the conference room was completely continuous. There's no sign of memory loss before or after any potential change. You can investigate her family background to see if there was any childhood trauma."
"We will definitely investigate that." Wei Hongbo frowned. "But after saying all this, are you trying to tell me you've discovered a new mental illness?"
"Of course not. I'm laying the groundwork, afraid you won't understand what I'm about to say next." Wei Hongsi said very seriously.
"Alright, then continue." Wei Hongbo was somewhat resigned.
"You've seen Li Yunxiang's resume, do you remember her educational background?" Wei Hongsi asked.
"She was a junior college graduate in landscape architecture." This was a major point of suspicion, so Wei Hongbo remembered it clearly. "Given her educational background, wouldn't it be quite impossible for her to operate that mirroring system of your company?"
"If it were just simple operation, that wouldn't be difficult. But if it's about model parsing and rendering, the difficulty becomes extremely high."
Wei Hongsi gave an example. "It's like apps on a phone. No matter how complex the functions, as long as someone teaches you, getting started and using it isn't hard. But if you had to write an app yourself to achieve a specific function you want, the difficulty is on a completely different level."
"This point is the hardest for me to understand." Not getting a definitive answer, Wei Hongbo pressed on. "According to what your Director Meng said, she suddenly 'got it' this March, her learning ability improved by leaps and bounds. Would that be enough to give her the corresponding capabilities?"
"People who suddenly 'get it' during learning are actually not uncommon, but the prerequisite is a certain degree of accumulated foundation. You can't create something out of nothing."
Wei Hongsi also avoided making a definitive conclusion, sticking to the facts. "Specifically regarding the advanced application of the Cognitive Mirroring System, at the very least, one needs a considerable foundation in mathematics and mathematical thinking. This isn't something that can be achieved overnight."
"Hmm, makes sense, very logical." Wei Hongbo rubbed the stubble on his chin.
He couldn't help but recall the painful experience of being tormented by advanced mathematics and linear algebra during his university days, and that was just the foundation of what his brother called the "mathematical foundation."
The thought then crossed his mind—could Li Yunxiang have been a commercial spy in disguise? Once her parents arrived, a DNA test would be very necessary.
Although this idea was a bit far-fetched, in Wei Hongbo's view, it was probably more reasonable than mastering mathematics in two or three months.
"Bro, you know about brain-computer interface technology, right?"
"I know a bit. Aren't there many technological achievements already commercialized?"
"If Li Yunxiang obtained knowledge, abilities, and a consciousness that originally didn't belong to her through a special kind of brain-computer interface technology, wouldn't that explain everything?"
"Huh?" Wei Hongbo looked at his brother suspiciously, seeing his serious expression, not at all like he was joking. "Does such technology really exist?"
"While there are no public reports, if it really did appear, I wouldn't be surprised at all." As he said this, Wei Hongsi felt an inexplicable surge of melancholy for some reason.
"My teacher once saw declassified files on this subject. According to him, in the latter half of the last century, both superpowers secretly conducted research in this area and had already made substantial progress. It was just that the side effects were too severe, and key technologies were difficult to break through, so those achievements could only exist in the laboratory.
"Later, after the confrontation between the two major powers ended, this type of experiment was strictly prohibited due to serious ethical and moral issues, and the related technology was never made public."
Wei Hongbo caught the hidden implication and quickly asked, "What were the side effects?"
"For example, loss of part of one's self-awareness, or severe deviations in perception of the outside world, and also triggering abnormal brain discharges, and so on." Wei Hongsi paused for a moment. "The symptoms of epilepsy are caused by abnormal brain discharges."
Wei Hongbo couldn't help but feel a stir in his heart.
Epilepsy! Wasn't that precisely Li Yunxiang's official cause of death!
Although this was all his brother's speculation, it undoubtedly could string together all the abnormalities that happened to Li Yunxiang.
"Can we find evidence?" he asked somewhat urgently.
Wei Hongsi said, "Perhaps we can. The voiceprint analysis I mentioned earlier is one path, at least it could serve as a piece of indirect evidence, right?"
Wei Hongbo thought for a moment and slowly nodded.
If two consciousnesses existed within one person's body, although there would be no difference in physiological structure and the vocal organs would be identical, under the control of different consciousnesses, differences in tone, intonation, breath, etc., would exist and could be distinguished.
"Another thing is the autopsy. If Li Yunxiang really had information implanted via a brain-computer interface, there should be some traces left on her skull or brain." Wei Hongsi said thoughtfully. "These traces might be extremely, extremely minute. You can remind Chief Xin to be sure to examine it very carefully."
Chief Xin's name was Xin Long. He was the bureau's chief forensic pathologist. Wei Hongsi also knew him and had even shared a meal with him once.
"Hmm, I'll remind him." Wei Hongbo nodded. If those traces could really be found, it might become an important breakthrough.
Wei Hongsi said, "Our company organizes annual health check-ups. Later, you can ask our Director Wu when the Environmental Maintenance Staff's health checks started. This might also explain why her learning ability suddenly improved so dramatically starting in March."
"Hmm, the material he gave includes health check records. I'll check the specific timing later. Anything else?"
Wei Hongbo felt this was useful information. Pinpointing precise time nodes would be very helpful for the subsequent investigation.
"That's all I can think of. The rest is up to you. If there's anything else you don't understand, you can ask me anytime." Wei Hongsi said, letting out a light sigh.
The task point clearly stated it was to assist in investigating Li Yunxiang's true cause of death. This was all he could do; the rest could only be entrusted to his brother and his team.
Wei Hongbo nodded silently. A moment later, he caught on. "You're working now. Do you talk to your colleagues at the company like this too?"
"What's wrong?"
"Be careful in the future. I'm afraid you'll get beaten up!"
