Xia Jinyu stopped a taxi at the school gate and told the driver an address that Mu Zi was not familiar with.

Along the way, Mu Zi silently looked at the night speeding by outside the car window, thinking about the messy thoughts, and unconsciously came to the door of a community that looked quite upscale.

Entering the gate, passing through a rectangular fountain square, through several green paths full of flowers and plants, two people stopped in front of a 35-story building. Xia Jinyu said to Mu Zi: "This is it." You memorize the house number, and after school tomorrow night, you can just take the car by yourself. ”

Mu Zi nodded, and then followed Xia Jinyu into the building and took the elevator to the 21st floor. Walking to the door of the No. 2 household, Xia Jinyu took out a key and handed it to Mu Zi, "You take this key first, and then return it to me when you don't want to live here." ”

"Thank you, I'll keep it safe." Mu Zi said and opened the door with the key. A dull air came over me, mixed with the smell of dust and decoration materials.

"This house hasn't been taken care of for a long time, and it smells a little bad." Xia Jinyu casually turned on the downlight in the living room, feeling a little sorry. "You should settle for a moment tonight, and it should be better to open the windows for ventilation."

"It's okay." Seeing that Xia Jinyu was so polite, Mu Zi waved his hand again and again, "You don't have to care about this little thing." ”

Xia Jinyu smiled, threw the heavy schoolbag on the ground, and then took Mu Zi to familiarize himself with the structure of the whole house.

This is a four-bedroom, two-living room and two-bathroom house with an area of about 130 square meters. The walls are painted in the color of cheese, with sober wallpaper and simple wall decorations, which looks warm and cozy. In addition to the various wardrobes, shoe cabinets and cabinets installed during the renovation, as well as the sanitary ware in the toilet and bathroom, there are only a few finished pieces of furniture in the whole house. Like the tempered glass coffee table and fabric sofa in the living room, the solid wood double bed in the master bedroom, and a black desk in the study, there is nothing more.

Because no one has cleaned it for a long time, a layer of dust has fallen in the room. When a person passes on the floor, they leave a faint row of shoe prints.

After Mu Zi walked around the house for a while, he asked Xia Jinyu curiously, "Why is this place so empty?" Is your family not planning to move in? ”

Xia Jinyu explained: "This house was originally bought by my parents when my brother graduated three years ago to marry his wife. As a result, a few years have passed, and my brother doesn't even have a girlfriend, so the house has been empty here. ”

"Where does your brother live now?"

"Single apartment, he doesn't like to live alone in such a big house."

"Yes...... Mu Zi said a little apologetically, "I'm really sorry, the new house was inhabited by an outsider like me first." ”

"It's fine." Xia Jinyu waved his hand and said half-jokingly, "Anyway, he won't be able to find a girlfriend for a while." When he gets married, the family will definitely buy him a new house again. I guess it's going to be sold. ”

The two sat on the sofa and chatted for a while, and Xia Jinyu told Mu Zi some more things, telling her to lock the door when she slept and not open the door to strangers. If you need help, just call him at any time.

After Xia Jinyu left, Mu Zi opened all the windows for ventilation. The neighborhood is very quiet, the evening breeze rustles the leaves, and the grass downstairs is full of insects.

Mu Zi used the rag in the bathroom to simply sweep the dust in the house, and then took a comfortable hot shower in the bathroom. By the time all this was done, it was already half past eleven o'clock in the evening.

Because there was no bedding on the big bed in the bedroom, and the mattress on it had not been opened, Mu Zi could only sleep on the sofa in the living room for one night. Even so, she felt much more at ease than going back to her own home, across the street from the house where the two people had just died.

She sat on the sofa and took out everything in her schoolbag and put it on the coffee table, ready to study. Suddenly, a white envelope fell out of a pile of rolls. As soon as he saw that thing, Mu Zi's heart, which had just been a little calm, became sad and tangled again.

She involuntarily picked up the envelope and pulled out the letter again.

"Muzi, you bad woman, give me back my Xiaoyan." This short but murderous sentence seemed to have magical powers, and every time Mu Zi read it, she felt as if her heart had been pierced by something, and the pain was so painful that she could barely breathe.

"Xiaoyan, I'm sorry, I didn't mean to......" Mu Zi clenched her fists tightly, and the edges of the letter had been crumpled and deformed by her. Where the hell are you? I miss you so much, please come back soon...... "tears" dripped down the letterhead, dripping on the bright red letter, blurring the red ink stains.

Mu Zi was immersed in sad memories, and the past was surging towards her like a tide. However, just as she was about to slowly fall towards the abyss of memory, a rapid and powerful knock suddenly sounded outside, blocking all the emotions that Mu Zi had just surged up.

Mu Zi came back to his senses, quickly wiped away his tears, and walked towards the door suspiciously. I wondered who would knock on the door so late? Could it be that Xia Jinyu is back again?

"Who?" She asked cautiously, peering out the door. At this look, she was instantly stunned, because the person standing outside the door was not Xia Jinyu, but his brother Officer Xia Shi.

"I'm Summer Time." The man outside the door replied.

Mu Zi froze for a few seconds, then slowly opened the door and pretended to greet Xia Shi easily, "Good evening, Officer Xia." ”

Xia Shi said "um", which was a response to Mu Zi, and then strode into the living room, looked around, and asked, "Where is Jin Yu?" Have you already gone back? ”

"yes, left an hour ago. Are you looking for him? ”

"No, I'm not looking for him." Xia Shi said and handed a large plastic bag to Mu Zi, "I happened to pass by here when I got home from work, and I will bring you some water and food." ”

"Thank you." Mu Zi gratefully took the plastic bag in Xia Shi's hand, opened it and took a look, it contained various snacks such as biscuits, cakes, chocolates, as well as milk, mineral water and drinks. Unexpectedly, this rough-looking man was actually so careful, and Mu Zi's heart suddenly felt warm. She put the bag next to the coffee table and said to Xia Shi, "Your work is really hard, you only got off work so late." ”

"It's not because of last night's case." Xia Shi replied with a wry smile. Recalling his experience this day, and thinking that he would continue to handle cases with Gu Song from now on, he felt very tired.

Mu Zi asked with interest, "Officer Xia, is last night's case any eyebrows?" Do you know who the murderer is? ”

Xia Shi shook his head, he really didn't want to talk about it anymore. He looked at Mu Zi's delicate and clean face, and his brows couldn't help frowning. "Muzi, did you cry just now? Did Xia Jinyu's kid bully you? ”

"Huh?" Mu Zi was taken aback, and hurriedly reached out to touch his eyes. There is still some heat around the eye sockets, and the traces of crying must still be obvious. "No, I just remembered some unhappy past, which has nothing to do with Xia Jinyu at all."

"That's good." Xia Shi breathed a sigh of relief, "If he dares to bully you, you will ......" Before he finished speaking, Xia Shi's eyes were attracted by the printing paper spread out on the coffee table.

Mu Zi followed Xia Shi's gaze and "chuckled" in his heart. But it was too late to hide it, Xia Shi had already taken the piece of paper in his hand. The words on the paper and the traces of tears made Xia Shi wonder. He looked at Mu Zi's slightly red and swollen eyes again, and asked seriously and seriously, "Are you crying because of this?" What exactly is written on this? ”

Mu Zi was a little flustered for a while. She didn't know where she got the courage, so she snatched the letter back from Xia Shi's hand and replied in a panic, "No, it's nothing." The ...... that my classmates jokingly wrote"

Xia Shi certainly didn't believe this answer. He stared at Mu Zi intently and asked again, "What the hell is going on?" ”

"It's really nothing!" Mu Zi yelled impatiently, and then realized that his reaction was too abnormal. She turned away, dodging Xia Shi's sharp gaze and said, "It's just a boring prank between classmates, you don't need to take it to heart." I'm sorry, Officer Xia, I'm going to study, please go back. ”

The drastic change in Mu Zi's attitude made Xia Shi feel inexplicable, but he was not angry with Mu Zi. He thought he was too careful, after all, what was a girl of this age thinking, and how to get along with her classmates, he was not completely able to understand it.

The two of them froze in place for a moment, and Xia Shi said to Mu Zi: "Okay, I'll leave now, and you can rest early for a while." With that, he turned and walked towards the door.

Listening to the footsteps of Xia Shi gradually moving away, Mu Zi never looked back. Her heart was struggling violently. Do you want to stop him? Do you want to keep him? This was a once-in-a-lifetime opportunity, and she couldn't let Xia Shi just leave.

Just as Xia Shi opened the door, one foot had already stepped out of the door. Mu Zi suddenly turned around, plucked up his courage and shouted, "Officer Xia, please wait!" ”

Xia Shi turned his head, looked at Mu Zi's somewhat red face, and asked in surprise, "What's wrong?" Do you have anything else? ”

Mu Zi nodded, waved the piece of paper in his hand and said, "Don't leave yet, I have something I want to ask you for help." ”

Xia Shi raised his hand to look at the time, retreated back into the room, and gently closed the door.
