"Bike sharing!" Shen Yu and I answered this question in unison. After saying that, the two of us looked at each other.

I took the lead in removing my eyes and unconsciously coughed dryly: "Many shared bicycles have been artificially destroyed with electronic locks, and you don't need to log in to the APP to ride directly." And the journey from school to Yao's house takes an adult male to ride in less than an hour and a half — enough time for Yao Xia to travel back and forth in one night. So that there are no traces. ”

"What about his classmates? They said he didn't come home at all. Xiao Yu was still puzzled.

Lin Ying had completely figured it out, and she explained: "I learned before, one of Yao Xia's roommates went to an Internet café outside and didn't go back to the dormitory at night, and the other two went to the library with Yao Xia to study late after dinner. After that, Yao Xia returned to the dormitory, and they switched to the study room to prepare for the exam all night. The three of them all returned to the dormitory after dawn the next day - we had fallen into a blind spot, thinking that Yao Xia had no transportation, and if he wanted to go home on a temporary basis, he would not be able to walk, so we thought that he could not go home on the night of the crime. ”

Xiao Yu suddenly realized: "I see." Worthy of the captain! ”

"What else do you have to learn?" Lin Ying patted Xiaoyu and said to Yao Yufeng, "The rolling pin is physical evidence and needs to be handed over to us for inspection." ”

"Hey, I'll get it for you." Yao Yufeng went into the kitchen to get a rolling pin.

"The package you want." Yao Xia held the plate in one hand and put the food in front of the table with the other. It's strange to say, obviously they are three women and one man, but they only ordered a single package.

"I'll just eat the salad." Xiao Yu said.

"I'll just eat chicken nuggets, Mr. Shen, I know that you lose weight, do you want to nibble on corn?"

"No, bring me a glass of boiled water." Shen Yu said indifferently.

"Let's eat a hamburger." Lin Ying handed me a big burger, and then turned back to Shen Yu and said, "You are in a very jumpy state, one day of overeating, and one day without even eating a vegetable leaf, is this healthy?" ”

"Just take care of yourself, can you?" As soon as he mentioned eating, Shen Yu suddenly became nameless.

Yao Xia has been working part-time in the restaurant for more than half a year in his spare time, watching these people chatting unhurriedly, although he thinks these people are a little weird, he still maintains a professional attitude, and said with a smile: "Your meal is ready." ”

"Hey, wait, don't go." Xiao Yu stopped him and said.

Yao Xia was stunned for a moment: "Is there anything else you need help with?" Lady. ”

Xiao Yu took out a long plastic bag from his schoolbag, and a rolling pin lay in the bag. Yao Xia saw the rolling pin, and his face changed suddenly.

"Acquaintance, huh?" Xiao Yu said as he glanced at the rolling pin.

"Who are you? Have you been to my house? Yao Xia was anxious all of a sudden.

"Look, I'm impatient before I speak, and I'll have a chance for you to speak in a while." Lin Ying took out her police officer ID and shook it, "We are policemen, you ask the boss for a leave, let's go to the café opposite to talk." ”

"It's none of my mother's business!" Yao Xia said excitedly.

"You know, if you want to have something to do with your family, I'll take you away, and you still have to talk here secretly?"

……

I devoured the burger, and then we moved on to the café opposite. SHEN YU ORDERED A GLASS OF ESPRESSO AND DRANK IT SILENTLY.

"You don't eat and drink strong coffee all day, aren't you afraid of stomach perforation?" Lin Ying asked with concern.

"Leave it to you."

"Teacher Shen, this is called weight loss, tsk," Xiao Yu said admiringly, "negative calorie intake." ”

"Yes, Yan Zhu doesn't care about others, don't straight men always persuade their girlfriends to pay attention to their bodies and drink more hot water? Alas. Lin Ying spoke again, not looking like a captain at all.

I lowered my head vigorously, not daring to look at Shen Yu, for fear that she would be angry, after all, I didn't help her stop Hua Yu from eating and drinking yesterday.

But seeing Lin Ying and Xiaoyu tease Shen Yu one by one, I really can't help but want to say a fair word and ask them to be kind: "Why don't I care about her?" I said, can you get down to business? Don't pay attention to other people's body and food all day long. ”

"Shut up, you two." Shen Yu finished his espresso in one gulp, glared at the two of them, and then turned to me again, "You shut up too." ”

At this moment, Yao Xia pushed the door and came in. This time, they really kept their mouths shut.

Yao Xia looked around and confirmed that there was no one he knew, and then he came over and sat beside me.

"Let me state first, that night, I did want to beat him hard, but I didn't want to kill him, and it didn't work out in the end."

"Can you tell us more about that?" Lin Ying asked with a serious face, not at all like the little look when she teased Shen Yu just now.

"Well, when I came back from self-study that night, I cleaned up my review materials and found that an important material for the next exam had been left at home. I thought I hadn't been home for a long time, so I was going to go home to see my mom and pick up some things.

"As soon as I saw the time, it was about to be the last train back to Yuntang Town, so I rushed out. As a result, when I changed buses, I found that the last train had just passed. Originally, I wanted to call an online car-hailing, but I thought it was a bit expensive, and I wondered if I would wait until tomorrow morning to go back.

"When I was hesitating, I noticed that there was a shared bicycle next to me, and the car was obviously broken, and the combination lock was actually left open and thrown there. I figured out that the bus stop wasn't too far from home, so I pedaled on that bike and left.

"When I got home, as soon as I saw my mother's bruises and scars, I knew that he was bullying my mother again while I was away from home. I immediately became furious, copied a rolling pin, and rushed towards the Xinyunli community.

"Shang Weimin is usually a drunken putty, and every day when he comes home after drinking, I wonder if I can intercept him halfway, anyway, what kind of way he beat my mother, I will give him a look!"

"You're taking a shortcut, aren't you?" Shen Yu suddenly asked.

"Yes, it's just those old alleys where no one lives." Yao Xia suddenly stopped when he said this, and his face changed, as if he remembered some terrifying memory.

"Then why didn't you go to Shang Weimin later, if you were there, he might not be dead." Lin Ying asked.

"Because he saw the ghost in the old alley." Shen Yu spoke naturally, as if she was also on the scene.

"Ah," Yao Xia exclaimed softly, "how do you know? Did you see that too? Could it be that you weren't there that day? ”

"We weren't there, but that explains one thing, and that's why the ghost didn't appear in the massage parlor's surveillance video." Shen Yu continued, "You were holding a rolling pin, and you originally wanted to take a shortcut and go straight to Yuntang Street, but in the old alley, you saw a faint and strange shadow in front of you. ”
