Li Xiyue said, "Of course! In this day and age, people think that electronic watches are advanced and stylish, while mechanical watches are considered not high-tech enough!"
"They'll realize later that mechanical watches are still valuable in the end!" Mi Bao said.
Li Xiyue had Mi Bao set up a spatial passage, through which she returned to her home.
By the time she got home, the sun had long since set.
Cheng Xiaohui waited for Li Xiyue at the door of her house. This child was always causing her so much worry. She was afraid that something had happened to Li Xiyue again.
Li Xiyue waved to her mother from the alley entrance.
Cheng Xiaohui finally felt relieved when she saw her daughter come into view.
She waved to her daughter as well.
A ray of the setting sun shone on Cheng Xiaohui, bathing her in a reddish glow.
Looking at Cheng Xiaohui, and at the neighbors washing vegetables and cooking in the alley, Li Xiyue felt the scene was as beautiful as an old photograph…
She walked up to Cheng Xiaohui and said, "Mom, why did you come out to wait for me again? I'll be back after I've finished my business!"
Cheng Xiaohui said, "I can't rest easy until I see you come back. Come in and eat."
Li Xiyue linked arms with Cheng Xiaohui and asked, "Mom, what are we having for dinner tonight?"
Cheng Xiaohui said, "I made you sweet and sour pork ribs! I also cooked a pot of rice and stir-fried some potatoes with chili. How is it? Is it something you like?"
Li Xiyue nodded and said, "These are all my favorite foods, Mom. Your sweet and sour pork ribs are the best, so delicious!"
Cheng Xiaohui said with a smile, "Your dad loves this the most too! I made a lot today, so you two can eat as much as you want! Um..."
Li Xiyue noticed that Cheng Xiaohui paused halfway through her sentence and asked, "What's that?"
Cheng Xiaohui said, "I made way too much sweet and sour pork ribs today. Even if you two eat as much as you want, you still can't finish it. Why don't you take some to Teacher Du?"
She asked her daughter tentatively, afraid that her words might upset her.
Li Xiyue said, "Mom, why do you always think of him when he's the best? He's not your son."
Cheng Xiaohui said, "He is indeed not my son, but what if he is my son-in-law?"
Her voice was soft. Li Xiyue had always disliked Du Jingshan. Although she was eager to bring them together, she was afraid of upsetting her daughter. So she spoke the last sentence very softly, so softly that Li Xiyue could barely hear it.
But Li Xiyue's exceptional hearing allowed her to immediately catch the second half of Cheng Xiaohui's sentence.
Countless dark lines slid down her forehead; in their area, there's a saying that a son-in-law is like half a son…
Mi Bao said, "Your mom is fixated on Du Jingshan. I'm also wondering, what's so great about Du Jingshan?"
Li Xiyue said, "It's probably because he doesn't have any bad points, so my mom thinks he's pretty good. Never mind, let's not talk about him anymore. Anyway, I'm not going to deliver it!"
She and Cheng Xiaohui walked into the living room.
Li Wenbo had already set the food on the table. When he saw his wife and daughter come in, he quickly served his daughter rice.
Cheng Xiaohui's sweet and sour pork ribs were Li Xiyue's favorite dish. Before she knew it, Li Xiyue had eaten too much. What was even more unexpected was that a whole bowl of sweet and sour pork ribs was completely gone, even though she and Li Wenbo tried their best.
Cheng Xiaohui sighed as she looked at the few pieces of sweet and sour pork ribs left.
She said to Li Xiyue, "Alright, there's not much left to give away, so don't try to eat more and stuff yourself!"
Li Xiyue sucked her fingers and said, "Mom, what are you saying? I definitely didn't eat more because I was afraid you would send the ribs to Du Jingshan. It's just that your cooking was too delicious!"
Cheng Xiaohui said, "Okay, I got it, alright? Go wash your hands and go to bed, it's already dark!"
Li Xiyue obediently got up and went to the kitchen to fetch water to wash up.
She rubbed her stomach, which had been craving raw food. Was she eating too much today because she didn't want to send ribs to Du Jingshan, or because the food was so delicious?
Actually, she couldn't tell either way; it was probably due to both reasons!
After washing up, she greeted Cheng Xiaohui and went back to her room to sleep.
She returned to her room and immediately locked the door, then asked Mibao to set up a spatial passage for her.
She and Mibao went directly to the police station's evidence section through the spatial passage.
This contains evidence from various cases.
Li Xiyue walked around the room and accurately located the case file and evidence of Lao Sun's case.
She took out a pair of rubber gloves, skillfully put them on, opened the file folder, and watched as evidence was poured out.
She opened the envelope and pulled out the blank paper. It really was a blank sheet of paper, as clean as her face!
Li Xiyue frowned slightly and said, "What's going on? He couldn't possibly be so bored as to write a letter without a single word in it and then hide it in a secret compartment like a treasure?"
Mi Bao said, "Maybe he didn't have time to write it, and he didn't even know when he would die."
Li Xiyue said, "It's precisely because he didn't know when he would die that he should have written the letter in advance, right?"
After thinking about it for a while, Mi Bao realized that this logic seemed to make sense!
It said to Li Xiyue, "Is there another possibility that the words might disappear over time?"
Li Xiyue shook her head slightly. "Even if the ink quality was poor in this era, this wouldn't happen. At most, it would just get damp and the writing would become smudged!"
She held the blank sheet of paper, completely baffled.
Mi Bao said, "How about we have the space system analyze the paper's composition to see if it's any special kind of paper?"
Li Xiyue held the paper, looking at it from left to right, but couldn't see any difference between it and the others. However, she had no other choice but to put the paper into her space and let the system check its composition to see if it was a special paper.
After the system finished analyzing the ingredients, Li Xiyue was surprised to find protein in the ingredient list.
Honeybee was also surprised. It said, "How can there be such a high protein content on paper? That doesn't make sense!"
Li Xiyue said, "This is definitely not scientific. Such a high protein level is not right!"
"This isn't silk paper, where would it get such a high protein content?"
But she looked at the paper from left to right and there was nothing on it. Where did the protein come from?
Honey asked, "What foods contain protein?"
Li Xiyue said, "The highest protein sources are eggs or milk..."
When she mentioned milk, her eyes suddenly flickered.
She said to Mi Bao, "I've got it! There must be milk in this paper!"
She brought the paper close to her nose and sniffed it carefully.
Although it's unclear when the letter was locked in the secret compartment, a careful sniff reveals a faint milky scent on the paper...
