Yan No.1 Middle School.

In the quietest classroom on the top floor of the teaching building, apart from the sound of the teacher lecturing at the podium, there is only the rustling sound of flipping pages and the sound of pen tips rubbing against paper as writing.

The sound of the next class reading an English text came through the wall, covering up the whispers of a few boys in the corner of the last row:

"...The news from Chenghua is absolutely reliable."

"So He Qianjian just rushed out of the school like that?"

"It's so tragic. I was the last one to know that my birthday party was cancelled. I can't stay in school anymore."

As they were whispering to each other, the class came to an end. The head teacher packed up the lesson plan and said with a smile: "The first round of review is over today. We will start the second round of review tomorrow. At the same time, all courses unrelated to the main course will give way to the main course, including your clubs and the work of some students in the student union..."

——Ding-ling-ling.

The teacher paused, waited for the bell to ring, and then said, "So this physical education class will be your last in high school. Students, cherish it. get out of class dismissed!"

For a moment, there were cheers and wails mixed together, and almost all the students stood up, except for a few boys in the back row who still huddled together.

Chen Xu's height has increased rapidly since the beginning of his senior year. In just over three months, he has grown from just 1.7 meters to 1.82 meters. Every time he changed positions, he moved back a little, and finally moved from Jiang Chen's side to in front of Luo Ze. He heard them talking in the back during class, but didn't know what they were talking about. It was the last physical education class, and Luo Ze was still able to sit still and didn't rush out.

Chen Xu bumped Luo Ze's desk with his stool: "What are you talking about? It's the last physical education class, why don't you rush to play basketball?"

"Tsk." Luo Ze said without raising his head: "Stop making noise, I'm chatting."

"If you keep gossiping, you'll become a gossiper." Chen Xu fished out the basketball from under his desk, turned around impatiently a few times and said, "Are you leaving or not? If not, I'll leave first."

"You go first..." Luo Ze waved his hands like chasing chickens away, and moved closer to the person who was speaking: "Then what do you think is going on with the He family? There must be a lot of party invitations for rich people, and those who are going to He Qianjian's birthday party must be well-known figures. They must give an explanation."

Shen Xu, who had already walked two steps away, turned around and leaned over: "Who are you talking about?"

"He Qianjian." A boy said, "He's the one who's always below Jiang Shen in the joint exams."

"He Qianjian from Chenghua?" Chen Xu was lying on the table with the ball in his arms, and he became interested: "What happened to him?"

"he……"

…

"Jiang Zi, Jiang Zi!" Chen Xu sat down at the table in front of Jiang Chen, "I'll tell you some gossip!"

Jiang Chen didn't even raise his eyes and said casually, "What gossip?"

"He Qianjian, Min Di's brother, is celebrating his birthday with you tomorrow, did you know that?" Shen Xu leaned over and said, "For some reason his birthday party was cancelled, and he was so angry that he ran away from school. I heard he even smashed a phone."

Jiang Chenbi paused: "What's going on?"

"I don't know." Chen Xu touched his chin and chuckled twice: "Do you think Brother Min knows about this? Although he is his biological brother, their relationship is so bad. Do you think if I tell Brother Min about this, will he be happy or not?"

Jiang Chen had several guesses in his mind, but he couldn't figure out what they were. Tomorrow was the day he officially turned eighteen. Regardless of whether the He family canceled He Qianjian's birthday party because they knew something, he had the absolute freedom to choose.

"Jiang Zi?" Chen Xu waved his hand. Seeing Jiang Chen staring at the formula on the draft book thoughtfully, he said with a sigh, "What kind of problem can make our Jiang Shen so obsessed? He has been calculating for so many days without a break. Come on, you continue to be obsessed with the formula. I'll go down first. After I find Brother Min, I'll go to the stadium. See you at the stadium."

Most people in the classroom had left. Jiang Chen took out his cell phone from the drawer and went to the rooftop on the other side of the corridor.

"D? We haven't been in touch for a long time since our last cooperation ended. What do you want from me?"

On the empty rooftop, the whistling wind made Jiang Chen's voice a little vague: "Help me find out why the He family canceled He Qianjian's birthday party. This matter has caused a big fuss. I believe you can give me an answer within ten minutes."

"You really think highly of me." There was a few low laughs from the other end: "But in order not to disappoint the big-spending old customers, I must do my best."

After hanging up the phone, Jiang Chen turned around and leaned on the railing to watch his classmates playing basketball on the playground. When he saw Shen Xu hit a three-pointer, he jumped up and hugged Luo Ze next to him, with a faint smile on his face.

In less than five minutes, the bell rang.

"Did you find out?"

"I'm sorry, this matter has indeed caused a big stir, but the cause has not been found yet." The voice on the other end became a little deeper: "Now almost everyone is speculating on the reason why the He family canceled the banquet. The information is too mixed, and it is difficult to purify the truth."

"The He family is now a solid block and has not leaked any information. There is no movement from He Yanjun, He Yanya is still in the laboratory, and there is nothing unusual about He Yanfeng's Tuanan Group. But what is suspicious is that He Yanfeng and his wife took their little daughter, who was supposed to go to cram school today, to the He family's old house early in the morning and have not come out until now."

"I guess this should be a family affair of the He family. It is very likely that it happened suddenly, but it has a significant impact on the He family."

Jiang Chen pursed his lips, remained silent for a moment, and said calmly: "I understand, the money will still be deposited into your account, thank you."

"No thanks." The other side laughed and said, "No reward without merit, this message is just a token of appreciation from an old customer."

"Thank you."

Jiang Chen put away his phone, turned around and went downstairs. As soon as he reached the playground, he saw the monitor Tang Qixun running over breathlessly, "Director Liu asked me to ask you to go to the principal's office."

Jiang Chen: "Do you know what it is?"

Seeing his calm appearance, Tang Qixun could not help but push him towards the office building. "I don't know, but it must be something important. Director Liu is very anxious and has come out to look for you several times. You better hurry up, otherwise he will come out all the time and we won't be able to play freely on the playground."

Jiang Chen clicked his tongue and turned around to ask, "So you're using me to reload your bullets, right?"

"How can I do that?" Tang Qixun laughed innocently. "This is the last PE class, and everyone wants to relax. When Director Liu comes out, couples don't dare to hold hands. For the happiness of the brothers, you have to make a sacrifice."

Before they reached the office building, Jiang Chen and Tang Qixun ran into Director Liu. Director Liu ran over to Jiang Chen as soon as he saw him and said anxiously, "Where have you been? I can't find you. Come with me."

Jiang Chen was dragged by Director Liu to the door of the small meeting room in the office. He calmed his breathing and said to Jiang Chen in a low voice, "When you go in later, just talk as usual. Professor Xiang is also in there, don't be nervous."

"Grandpa Xiang?"

"Yes." Director Liu patted Jiang Chen on the shoulder and smiled: "Okay, go in."

The door of the conference room opened, and five people inside, one sitting and four standing, all looked over here.

"Student Jiang Chen, come in quickly." The principal came over, smiled kindly at Jiang Chen, turned around and said to the two people, one sitting and one standing, "We'll leave first."

The middle-aged man standing said, "Thank you for your help."

The principal smiled and patted Jiang Chen on the shoulder: "Perform well."

Jiang Chen nodded slightly, his eyes swept across the epaulettes of the middle-aged man standing by the window and the two young soldiers beside him, and landed on Mr. Xiang.

The door of the conference room closed again. Xiang Lao waved to Jiang Chen and said with a smile, "Xiao Chen, this is Major General Wu from the 17th National Defense Research Institute of the military."

The middle-aged man glanced at him with his dignified eyes. Jiang Chen raised his eyes, polite but not evasive, and smiled: "Hello, Major General Wu, I am Jiang Chen."

"Hello, Jiang Chen."

After saying hello, Wu Shao pulled out a chair, gestured to Jiang Chen to sit down, and said straight to the point: "I learned from Mr. Xiang that you independently developed an image processing system, and I wanted to find out more about it from you."

Jiang Chen sat down calmly and said, "What does Major General Wu want to know?"

"Its military use." said Major General Wu.

Jiang Chen smiled and said, "When developing this system, I did consider its multiple uses, including military and medical uses, but before I answer you, I would like to ask a question."

Major General Wu: "Speak."

"Are you coming to me this time for the country or in a personal capacity?"

"In my personal capacity," Major General Wu said, "but after understanding your system, I will decide whether to report it to the National Military Research Institute based on the situation."

Jiang Chen nodded slightly, then smiled and said, "Major General Wu, please forgive me for not being able to discuss with you the image processing system I am currently researching. As a scientific researcher, it is my responsibility to protect my research results. I hope you can understand."

Major General Wu paused, his tone difficult to discern: "Little friend, do you think you are already a scientific researcher?"

Jiang Chen smiled: "What do you think a scientific researcher is?"

"At least you can produce certain results." Major General Wu said, "So I came to you today to confirm whether you can become an excellent scientific researcher."

"I already am."

The young man raised his eyebrows slightly and spoke in a calm tone. Although his words sounded arrogant, they did not make people feel bad. Instead, they made people feel that he was full of energy and made people feel convinced.

There was a trace of surprise in Major General Wu's eyes, but there was a hint of smile on his lips: "How do you prove it?"

"If you use the name of the country, I can prove it at any time."

"In that case." Major General Wu stood up, turned around and walked directly out the door: "Then prove it to me."

The two soldiers who had been standing at the door saluted, and when Major General Wu walked out, the young soldier who was half a step behind quickly gave Jiang Chen a thumbs up and followed him.

Mr. Xiang stood up, pointed at him, and said with a smile: "You are really amazing, let's go."

Jiang Chen smiled and supported Mr. Xiang until they got into the low-key SUV at the school gate.
