Lin Lan's phone suddenly rang, she was stunned and said: "it's president Wu's!"

"Take it!" Liu Cheng nodded.

Lin Lan gave a "um" and then picked up the phone, "headmaster Are you back? "

"Well, I'm in the office. Where are you now?" Said the other end of the phone.

"I'm on the side of the teaching building. I'll come back in a moment!" Lin Lan said.

"Well, come here as soon as possible. I have something to tell you!" The voice on the other end of the phone was very urgent. It was obvious that the man was worried.

"All right!" Immediately, Lin Lan hung up the phone and said to Liu Cheng, "there's president Wu..."

"You go, but be safe!" Liu Cheng said, he took out three silver needles from his body and handed them to Lin Lan, "take these three silver needles. If there is any danger, remember to throw them directly. They can save you!"

Lin Lan some, "really so serious?"

Liu Cheng laughed, deliberately ease the atmosphere, "it's not so exaggerated, but now is a special period, take this thing, just in case!"

Lin Lan nodded solemnly, pinned the three silver needles on the clothes, and then went down.

Cheng Haofeng watched Lin Lan leave, also want to follow in the past, but was stopped by Liu Cheng.

"Don't run around," Liu Cheng said with a frown. "I have something else to ask you!"

"What for?" Cheng Haofeng to him or always a little more timid, "I didn't provoke you!"

"Hey," Liu Cheng said with a smile, "it seems that you really love secretary Lin. don't miss any chance to get close to him!"

Cheng Haofeng raised her eyebrows. "Secretary Lin is sexy and beautiful. She is almost the most beautiful woman in the whole school. All the boys in our class regard her as their dream lover!"

"Ha ha, I didn't expect her to have such great charm. I'm really surprised," Liu Cheng said with a smile. "But do you know that people have boyfriends?"

"I know, it's just a waste," Cheng Haofeng said with disdain. "I've seen that man several times. He's a heavy smoker. I really don't know where secretary Lin sees that guy!"

Liu Cheng didn't expect that when Cheng Haofeng mentioned Lin Lan's boyfriend, he was so disdainful. He couldn't help laughing and said, "even you look down on him, but do you know that man was the dream lover of many girls in his early years?"

"Just him? Are you teasing me? " Cheng Haofeng seems to have heard a big joke, "it's really a dog day. When I think of secretary Lin sleeping with that spicy chicken every night, I feel sick. It's really a flower on the cow dung!"

Liu Cheng almost laughs and claps his hand on Cheng Haofeng's head. "What do you think of in your head, are you all grown up?"

"Well, Mr. Liu, I can't beat you, but you're beating me. I'm really fighting with you." Cheng Haofeng said.

Liu Cheng suddenly felt that this rich man was a bit cute, especially compared with his previous arrogance and desperation. He said with a smile, "well, if you don't start, I ask you, is there any relationship between you and Chen Qingqing beyond the boundary of friends? I've seen her picture. The little girl is very beautiful, too! "

Cheng Haofeng immediately waved his hand, "although Chen Qingqing and I often go home together after school, our relationship is not bad, but there is really nothing between us, we are not the type we like each other!"

"Oh? Do you like secretary Lin's sister Liu Cheng asked.

Cheng Haofeng face slightly a red, did not deny.

"What about Chen Qingqing?" Liu Cheng asked.

"What she likes is the kind that is more mature and has more prestige outside," Cheng Haofeng explained. "We students are not her food at all. Mr. Liu, if you have more prestige, maybe she is interested in you!"

Liu Cheng's heart moved, "did Chen Qingqing have a boyfriend?"

Cheng Haofeng said without thinking, "yes, and I have seen that man once!"

"Oh?" Liu Cheng immediately came to the interest, "who is that man? After Chen Qingqing died, where is he now?"

Cheng Haofeng frowned slightly and said, "sometimes I really don't understand these women. Secretary Lin, for example, looks good and has a good career. But my boyfriend is so weak. Chen Qingqing is a good student with good grades, but he just likes a little jerk!"

"Punk? Do you mean the person Chen Qingqing likes is a little gangster Liu Cheng is a bit surprised. He has seen Chen Qingqing's picture before. She looks pretty and is definitely a beauty. Besides, Lin Lan said that the girl's academic performance was good all the time. It can be said that she should be a little goddess in the class.

"Yes, it's a bar near the school. It's a resident singer. He's just a gangster. I don't know what Chen Qingqing likes about him!" Cheng Haofeng some hate iron not into steel said, "and heard that Chen Qingqing died, the guy did not show up, and even his news can not be heard!"Liu Cheng's interest is growing, "can you contact that guy, I'd like to see him!"

Cheng Haofeng is not stupid, and he is very smart. As soon as his brain turns, he immediately asks: "Mr. Liu, do you doubt Chen Qingqing's death and..."

He did not finish, Liu Cheng did not point out, just said: "if you can find it, help me find it, if not, I will let the police to find it!"

"Good!" Cheng Haofeng nodded, "give it to me!"

"By the way, does Chen Qingqing have any habits?" Liu Cheng asked.

"Well..." Cheng Haofeng thought, "she usually likes to write diary, before also advised me to write, but I am too lazy!"

"OK, take me to Chen Qingqing's house first!" Liu Cheng immediately decided, "a lot of people will write down what they dare not say or do in their diaries. Maybe we can find some other clues there!"

"Good!" Cheng Haofeng nodded, "do you want to go now?"

"Go Liu Cheng said, directly with Cheng Haofeng downstairs, before leaving, he quietly in the upstairs cloth a micro array.

After leaving the school gate, Liu Cheng and Cheng Haofeng drove straight to Chen Qingqing's home.

Half an hour later, they knocked on Chen Qingqing's door.

When opening the door was a middle-aged woman, Cheng Haofeng came forward to say hello and said: "Hello, aunt. This is Mr. Liu who is responsible for investigating Qingqing case. The leader sent someone down!"

Then he said to Liu Cheng, "Mr. Liu, this is Aunt Chen, Qingqing's mother."

The sadness on the middle-aged woman's face was hard to hide, but she still pretended to laugh and said: "Mr. Liu, Xiao Feng, please come in first!"

Liu Cheng nodded with a smile, "Hello, Ms. Chen, we have mastered new clues recently. We feel that Qingqing is not a simple suicide, so we want to have a deep understanding. Can you take me to her room?"
