Pei Muwan slowly said, "Nanny Yi is a famously kind person who has never gotten angry with anyone in her life, and I haven't heard of her having any enemies."
"Furthermore, Nanny Yi's social interactions were extremely simple; she barely ever left Yunyi Tower."
"Who stands to gain the most from her death? I can't think of anyone."
... Centurion Song said, "The investigation into Nanny Yi's social relationships is detailed in the dossier. Her maternal family, her friends, her former neighbors—all her relationships were thoroughly investigated. Fang Qian took 5 Squad Leaders and over 50 men under his command and spent half a month investigating these relationships, yet they failed to uncover anything useful."
Lu Zhenghai opened the dossier. Sure enough, the investigation into Nanny Yi's social relationships was extremely detailed.
He read for a long time, and indeed, there were no suspicious points.
After a long while, "Can the murder weapon be reconstructed?" Lu Zhenghai looked at Centurion Song.
"Fang Qian already had someone reconstruct the weapon based on the shape of the wound on Nanny Yi's abdomen. The reconstruction revealed a very ordinary, foot-long short sword, the kind that is everywhere on the market," Centurion Song said helplessly.
This truly is a baffling cold case. Investigating for a month and finding absolutely no clues—it's unprecedented.
You should know that Fang Qian is a famously skilled investigator, even within the Embroidered Uniform Guard!
"Nanny Yi was assassinated on the street. Were there no witnesses?" Lu Zhenghai asked again.
"No." Centurion Song's voice grew slightly louder: "So many people were coming and going, and it happened in an instant. We truly couldn't find any witnesses. Even Nanny Yi herself didn't see what the killer looked like, let alone anyone else."
Lu Zhenghai continued to flip through the dossier.
Centurion Song and Pei Muwan also remained silent, neither speaking nor urging him, just waiting patiently.
A full half hour passed. Lu Zhenghai closed the dossier. "If we can confirm the information in the dossier is correct..."
Centurion Song said solemnly, "To ensure accuracy, Banner Commander Fang even checked every single piece of information multiple times!"
Are you kidding? This is a case concerning the Grand Tutors Residence. Who would dare not take it seriously?
"If it is confirmed to be accurate, then I believe only two possibilities remain."
"Young Master Lu, tell us..." Pei Muwan's emotions clearly showed a slight fluctuation—it was anticipation.
"The first possibility is that a crazy person, mentally disturbed, committed a random killing, and Nanny Yi happened to be the victim. The second possibility is that the killer wanted to kill Miss Pei but couldn't, so they killed someone who was very important to Miss Pei."
Pei Muwan's beautiful face paled slightly. "A random killer? If there really was such a disturbed person, similar cases to Nanny Yi's would definitely have occurred recently within the Imperial City, but they haven't. Therefore, the killer murdered Nanny Yi because they couldn't successfully kill me?"
Lu Zhenghai stared at Pei Muwan. "So, Miss Pei, please try to recall: have you offended anyone? Preferably someone you offended within the last six months. If not, extending the timeframe is also acceptable."
While Lu Zhenghai questioned Pei Muwan, he was thinking about the [System intelligence] in his mind.
Sujin Pavilion? Judging by the name, it's probably a shop selling clothes or fabric.
What exactly does a shop like this have to do with the Grand Tutors Residence case?
He couldn't figure it out, so he decided to personally go to Sujin Pavilion to take a look.
"Miss Pei, take your time thinking. I need to go out and look for clues."
As Lu Zhenghai spoke, he walked toward the door.
Zhou Hu quickly followed him out.
Centurion Song cupped his hands toward Pei Muwan. "I will go take a look too."
Pei Muwan nodded. Judging by her expression, she was still deep in thought, considering people she had offended in the last six months.
After leaving the Grand Tutors Residence.
"Good job, Young Master Lu, that's impressive!" Centurion Song patted Lu Zhenghai's shoulder. "That idiot Fang Qian investigated for a month and never considered that the killer was targeting Pei Muwan..."
"It's not certain yet, but the probability is high. After all, a simple Nanny isn't worth such an elaborate assassination."
"Where are we going now? Are we going to Tongfu Restaurant?"
"Yes, let's go to Tongfu Restaurant first."
Lu Zhenghai said with a smile. He certainly wouldn't dare run straight to Sujin Pavilion; that would be too strange.
Don't treat ancient people like fools. If he accidentally exposed the existence of the [intelligence system], that would be bad.
Anyway, Sujin Pavilion wasn't far from Tongfu Restaurant.
After asking at Tongfu Restaurant, he would then go to some shops nearby to inquire.
He would just ask questions like, "Did you see Nanny Yi that day?" or "Do you know Nanny Yi?"
By asking around, he could gradually approach Sujin Pavilion.
Although, once he reached Sujin Pavilion, he would definitely have to interrogate them intensely—much, much more detailed than questioning other shops—which would still look very strange.
But at least the strangeness wouldn't be so obvious; it was much better than heading straight for Sujin Pavilion without a word.
The whole afternoon passed.
Lu Zhenghai and the other two first went to Tongfu Restaurant to ask for clues, but of course, they found none.
Afterward, Lu Zhenghai followed his plan, inquiring at shop after shop, gradually moving closer to Sujin Pavilion.
This felt like searching for a needle in a haystack, Centurion Song thought.
Could such a clumsy method of searching for clues really yield results?
But thinking of Lu Zhenghai's stunning performance in the case of Gao Shihan's death, he decided to indulge Lu Zhenghai's whim for now; it was only one afternoon, after all.
Before long, it was evening, and the sky was already getting dark.
Finally, they reached Sujin Pavilion.
Walking into Sujin Pavilion, Lu Zhenghai realized he had guessed wrong.
He had thought this shop sold clothes or fabric.
But in fact, it was a tailor shop.
The proprietress greeted them with a beaming smile, "Three officers, is there something I can help you with?"
