29 Buddha's Eye
Fang Chengjin continued, "Xia Yi has shoe covers in her shoe cabinet. If what she said is true, she lives alone most of the time, so why would she prepare shoe covers there? We should first investigate who has been in contact with Xia Yi during this period. We should go to the property manager to question them and, if necessary, retrieve the surveillance footage."
Zhou Yun nodded.
The two quickly returned to the security office and explained the situation to the person in charge, who then retrieved the surveillance footage from the 12th floor corridor over the past month.
After reviewing the month's worth of surveillance footage, the three of them found nothing. They noticed that Xia Yi was always alone, as she rarely went out, and when she did, she always carried an umbrella. It was already six o'clock in the afternoon, and dusk was approaching.
The security guard who was originally on duty outside came in with a boxed lunch. It was obvious that he was taking a break from his shift and eating. The monitoring room was small, and the security guard was eating alone on a chair next to it. The supervisor smelled the food and couldn't help but scold the security guard. He, as the leader, hadn't even eaten yet, and his subordinate was already eating. Besides, there were police officers handling a case nearby.
The young security guard immediately put away his lunchbox, came over, and said apologetically, "Captain, I'm sorry, what are you looking for?"
The team leader frowned. "Who has the resident in Building 7 with the eye injury been in contact with? By the way, you're usually out there monitoring the area, do you remember who?"
The young security guard leaned closer to the screen and exclaimed in surprise, "I recognize her! This homeowner has poor eyesight, and I often help her open the gate to the outside fence. She also has an older sister!"
Upon hearing this, Zhou Yun and Fang Chengjin exchanged a glance, their eyes lighting up.
Zhou Yun: "The information that Captain Lin sent didn't mention that she has an older sister!"
Fang Cheng looked at the security guard and asked, "Sister? Are there any security cameras?"
The security guard nodded. "Yes, yes, I remember that day she was about to fall, and I went to help her. A pretty girl also came up to help. I asked her a few questions, and the girl said she was her older sister who had come from afar to visit her."
As the security guard spoke, he pulled up old videos, up to two months ago.
Fang Chengjin: "Enlarge the video."
The security guard pressed the expansion button, and soon, the girl's face appeared in a not-so-clear but still discernible outline.
Zhou Yun sensed something was off from the security guard's words, "Where did her sister come from?"
The security guard scratched his head, then suddenly turned to look at the two of them. "Yes, Hong Kong Island. Just like you, we came here by ferry from there!"
Fang Chengjin suddenly interrupted, "Wait, let's go back to two minutes ago."
Xia Yi's older sister came over to help Xia Yi up, and Xia Yi stood side by side with her sister behind her.
Zhou Yun glanced at it. "Is something wrong?"
Fang Chengjin: "Look at Xia Yi's arm, it's slightly raised. This is clearly a defensive gesture. She doesn't want this so-called older sister to touch her at all."
Zhou Yun watched it a few more times and finally noticed this detail in the blurry part of the video. "So, the relationship between these two sisters is not ordinary."

"Xia Xue, Xia Yi's older sister, was a student at the same university as Xia Yi, and even her senior. Coincidentally, Xia Xue's sister majored in chemistry, was skilled in various chemical reagents, and after graduation joined a chemical plant, where she is currently a senior technician..."
Zhou Yun looked through the messages sent by Team Leader Lin, picking out the important information as she read it aloud to Fang Chengjin.
Fang Chengjin was standing in the room where Jiang Huai had the accident, smelling the scent emanating from the room.
The smell lingered. It was initially thought that the smell would disappear after the murder weapon was taken away by the colleagues at the station, but unexpectedly, the smell continued to linger in the room where the crime occurred.
Just now, Fang Chengjin called Zhou Yun to re-examine the crime scene. As soon as he entered the room, Fang Chengjin smelled that odor.
In the quiet villa, Zhou Yun's indifferent voice occasionally rang out in the air, along with the sound of her tapping on her phone screen and... the faint fragrance emanating from her seemed to wash away the filth of the crime scene.
Fang Cheng ignored these smells and focused intently on searching for the scent of oranges at the crime scene...
The first thing they noticed was the doorknob. Fang Cheng paused briefly at the doorway, then reached out and tried to grasp it. The scent was coming from the inside of the handle, indicating that the murderer had gripped it from the inside...
We can imagine that this person was someone the deceased knew. After opening the door and seeing the person, the person invited the murderer in, then turned around and went upstairs by himself. The murderer then closed the door himself.
Then... Fang Chengjin walked up the spiral staircase of the villa step by step. He deliberately walked close to the handrail, but found that there was no fragrance. Then he walked all the way to... the second floor, the crime scene.
"Xia Xue's company and subsequent work had no connection with Jiang Huai. In fact, she was their senior, and I didn't see any interaction between them in the messages sent by Captain Lin."
Zhou Yun looked up from her phone screen, puzzled. Things seemed to have fallen into another layer of confusion. She followed Fang Chengjin upstairs, only to find him standing at the top of the stairs instead of going any further. The moment she looked up, she almost bumped into him. Through Fang Chengjin's thin shirt, a strong muscle line was visible on his back.
"Furthermore, Captain Lin couldn't find out what grudge her sister had against her. The people he sent to stake out Xia Yi's old home only found out that Xia Yi's parents had passed away, supposedly due to a car accident, leaving an inheritance for the two of them. According to the neighbors, the two sisters seemed to have a decent relationship, but the family favored the younger sister more."
The air fell silent. Fang Chengjin did not give any response, as if he was deep in thought.
"What's wrong?" Zhou Yun couldn't help but ask him from behind, because he was standing at the top of the stairs and Zhou Yun couldn't come up either.
Fang Chengjin's gaze fell on the sofa.
I initially thought the aroma was from the cups, but I didn't expect it to be on the sofa too.
Fang Chengjin quickly walked to the sofa and bent down to carefully smell the genuine leather sofa.
At this moment, in Zhou Yun's eyes, he looked like a... police dog?
Zhou Yun quickly suppressed her wicked thoughts and strode to the sofa. Had she discovered something? She was about to bend down and smell it when Fang Chengjin scolded her.
"Do not move!"
Zhou Yun's back stiffened, and she dared not move for a moment.
Fang Chengjin brushed past her nose, approached Zhou Yun, and lowered his head in front of her.
Zhou Yun couldn't help but swallow.
"Step back." Fang Cheng frowned.
"Huh?" Zhou Yun subconsciously took a step back.
Why? Can't she smell it too?
Fang Cheng thought to himself: Zhou Yun's fragrance is getting stronger and stronger, so strong that he can't smell the sofa at all.
Fang Cheng sniffed the sofa like a police dog, and finally straightened up, satisfied.
"Now I know why the house smelled like the killer."
Zhou Yun listened attentively.
"Her (his) hand."
Hands? Zhou Yun raised an eyebrow.
Fang Cheng closed his eyes, and a scene unfolded in his mind.
"The murderer's hands smelled sweet. First, he touched the doorknob, then went up the stairs without holding the handrail, so the stairs didn't smell. Then he came to the sofa, sat down, and his hands unconsciously touched the sofa leather. Then there was the glass of poisoned water, and the poison powder was put into the water from his hands."
Zhou Yun listened, then had other questions: "What did the murderer use as a weapon to poison the victim?"
Fang Cheng suddenly turned around, staring at Zhou Yun like a cheetah, as if he wanted to devour her. His gaze was so fierce that Zhou Yun couldn't help but take a step back.
Fang Chengjin strode over and took Zhou Yun's hand.
Zhou Yun was startled and instinctively tried to break free.
Fang Cheng uttered aloud: "Fingernails."
Nails? Zhou Yun paused, her gaze falling on her fingers. The fluorescent pink cat-eye manicure was now sparkling and translucent.
This manicure was done a few days ago by Xiao Pan, who dragged her to the night market. As a police officer, she usually never gets manicures, but Xiao Pan, being a young girl, likes them, so she was forced to get one. She had no choice but to pick a color that wasn't too bright.
Zhou Yun suddenly understood. "You mean... the poison is hidden in the nail polish?"
Before Fang Chengjin could even nod, Zhou Yun immediately made another connection, "Then the murderer can only be a woman, and only women use things like manicures frequently. I'll call Captain Lin right away to investigate Jiang Huai's female friends!"
Fang Cheng gently pressed down on her hand as she was about to make a phone call. "There's no need."
Zhou Yun was surprised, "Why?"
Fang Chengjin: "Jiang Huai's interpersonal relationships are very simple. I have seen the personal information that Captain Lin collected about her before. Since she got married, she has been completely devoted to her married life with Zhou Yiming, running between the company and home. The only female friends she can contact are her family members. I now feel that there is no need to investigate Jiang Huai, but there is one person we can investigate."
Zhou Yun raised an eyebrow, a sudden thought flashing through her mind: "Zhou Yiming, Jiang Huai's secretly married husband!"
Fang Chengjin's lips curled into a slight smile. "Why?"
Zhou Yun frowned. "Intuition."
She couldn't explain why, but she found it very strange.
Fang Cheng bluntly asked, "Tell me, how many girls actually like Zhou Yiming?"
