At the foot of the mountain on the south side of the Hengling Mountains is Tongxi Middle School. This is a campus founded in 1903, and its motto is "scientific, serious, realistic, and motivated".

When the school was opened, students attended classes in the temple hall. It is rumored that when Zhu Yuanzhang planned to attack Jinling, he was stationed in the temple; After being called the emperor, he came to the temple to offer incense. As a result of his interest, he also wrote a poem:

In the past, the battle was busy, and the ambitions of Longxing and Fengyang were high.

If you don't think about it, you have to offer this peace incense.

Nowadays, the world has changed, the poems are difficult to verify, and the temples are nowhere to be found. Instead, there are teaching buildings, laboratory buildings, dormitory buildings and grassy stadiums...

Cheng Yong, the captain of the Criminal Investigation Brigade, arranged the work of each group, and then drove Wu Tianfang to Tongxi Middle School to find Chen Mingming, the director of education?

"Director Chen, it's all on vacation, and I'm still here to trouble you?" Cheng Yong got out of the car and shouted hello as he walked to the Academic Affairs Office.

"It's okay, it's okay. I'm on duty today, aren't you - busy too? A balding man of about fifty years old stood at the door of the office and smiled and replied:

"Air conditioning inside, cold outside! Hurry inside! ”

"Teacher Chen-" Wu Tianfang shouted:

Chen Mingming was his homeroom teacher for three years in high school, he was very naughty when he was studying, and Mr. Chen was very strict with him, otherwise he would have asked himself - it would be difficult to be admitted to the Jiangnan Police Academy.

After graduation, he would invite a group of old classmates to have dinner with Mr. Chen every winter and summer vacation, laughing about the past and talking about the future. It is because the relationship between teachers and students is very deep!

At 7 o'clock this morning, he saw Cheng Da and heard that the task was to go to Tongxi Middle School to investigate Liu Guanglan's daughter Yuan Shanshan?

He immediately thought of his homeroom teacher ...

"Director Wu - come on! I haven't seen you in half a year. Director Chen was a little excited:

He was proud that his students could become police officers and become leaders. Usually it is called "Tianfang", but today it is different - students come for business?

"I was going to invite you to get together during the 'winter vacation', but I didn't expect to draw the Criminal Investigation Brigade to help-" Wu Tian put in the door and introduced:

"This is Cheng Yong, the captain of the Criminal Brigade, and 'Cheng' next to He."

"Oh - I've seen it on TV... Young - it's better to be busy. Director Chen took out a disposable paper cup and wanted to make tea—

"Teacher-you sit, I'll soak-" Tianfang snatched the paper cup.

"Director Chen, I am also a graduate of Tongxi Middle School in the -93rd class (1). You taught me math for a month? Cheng Yong recalled.

"It's been almost 20 years - Captain remembers!" Chen Mingming said thoughtfully:

"In that class of mathematics, (1) class was taught by Mr. Ye... Should it be when he takes 'marriage leave'? I don't remember exactly. ”

"Mr. Chen has taught so many students and taught math well - we all thank you!" Wu Tianfang finished making tea and sat down.

"Like you in my class, after graduation - and the connection, I was impressed! Cheng Da? I've only been teaching for a few days - I can't remember. Director Chen looked at the two capable young men with pity, touched the shiny brains, and sighed:

"I'm old... You are so good, you have to do a good job! ”

"Teacher, you are a master of mathematics in Tongxi Middle School, the older you are, the more valuable you are!" After Wu Tianfang finished speaking, he felt inappropriate - added:

"We are trained by you, we can't give you 'shame'!"

"'Old' is the law of nature, and I don't teach just for the money – let it be. Wu Suo, you said on the phone: Do you want to know a male student in high school, named 'Li Gang'? I looked it up from the computer and found that there is one in class -7. The homeroom teacher is Mr. Huang Qiwen – who does not live in the school. I'll call him..."Chen Zhizhi Zhengse said, picking up the microphone on the desk:

He had a chance to be promoted to "vice-chancellor" in the second half of the year, only because he was 10 days over the selection criteria - he was not shortlisted ...

Teacher Huang promised to come to school within an hour.

Cheng Yong and Wu Tianfang temporarily bid farewell to Director Chen and walked to the stadium—

"When I graduated in '93, the hillside outside the courtyard wall was bare—" Cheng said:

"After our class had a 'New Year's Day party', we took bamboo and wood, and rushed there like crazy - we lit a bonfire... It's been a whole night! ”

"Cheng Da, that-you guys are wild enough! I'm 3 years later than you, Sven is more. After we finished the college entrance examination, we ran to Kala-OK, but - it was also an all-nighter. Tian Fang laughed.

"I used to talk about 'big changes in five years', but now it's the same every year! Just now, Director Chen said that he is old, and I feel that I am 'old'. Alas-" Cheng Yong rubbed his red eyes and took a breath:

He is not only worried about the "headless disappearance case" in front of him, but also thinking about the upcoming New Year, how can he "pay New Year's greetings"?

"What are you sighing? Zhang Ju's 'seat' - not reserved for you yet? Tian Fang smiled and looked at the captain and said:

He has seen the first two criminal investigation captains "Niu Meng and Zhang Zhengyi", who were promoted to deputy directors in charge of criminal investigation step by step, and he naturally thinks that Cheng Yong will be promoted in the next step!

"Can't solve the case? Also talk about the 'seat' of the finches... It's still cold outside, let's go back to the Academic Affairs Office-" Cheng Da walked back and continued:

"Brother, you talked to Liu Guanglan about the 'Yuan Butcher's suicide' back then. After we find her through Ms. Huang, or will you talk? ”

"Okay. You probably don't know—I talked to her once—" Wu Tian slowed down, and then told him about "Liu Guanglan's theft of Wang Daohan's handbag"...

"So, after her husband died, Liu Guanglan did not live with Jin Shorty, but went to Jianshan to work, and even married a businessman, and almost entered the 'detention center'?" Cheng Yong frowned and hissed:

This woman is not simple—

She has a relationship with Ning Yuanfu, Yuan Mingjun, Jin Honglei, Wang Daohan and other 4 men, except for her husband, the other three layers of "intimate relationships" are indescribable and unclear? And can you actually think of it - design to force lovers to comply?

Could it really be that she "murdered" Ning Laizi...

Wu Tianfang's mobile phone rang, and after he answered, he immediately said:

"Cheng Da, Director Chen said: Teacher Huang has arrived, waiting for us in the office of the mathematics grade group; He's got something going on at school - he's going to be busy. Let me tell you that. ”

"Good. Hurry up-" Cheng Yong took a step, and said as he walked:

"Tianfang, Li Gang is suspected of fighting, don't tell Teacher Huang more about it? The point is - Liu Guanglan mother and daughter? ”

"I understand-" Wu Tianfang trotted to follow:

In the morning, Cheng Da asked him to figure out how to approach Yuan Shanshan without showing the mountains and without dew? He went to the police network to check, and accidentally searched for a record about "Yuan Shanshan"—

Last night, there was a public security case in which Li Gang assaulted others, and Yuan Shanshan was an eyewitness at the scene. He checked the file and found that Yuan was a classmate of Li. Li Gang took Yuan Shanshan to eat at the food stall, and the two young men at the next table looked at Yuan twice, and the two sides fought.

The materials of the conversation were talked about by the police officers of the Ji'an Police Station, which was relatively rough. The host police had planned to notify the school this morning? Fortunately, Cheng Da contacted the law firm - the news was blocked in time...
