Ma Guanghua was first surprised by Cao Wu's sudden back-to-back with him, then his heart was weak, and then he became even more angry because he was actually weak-hearted.

He knew in his heart that this band had won glory for the school, and it was a sweet spot in front of the school leaders, and he couldn't clean it up.

But he just couldn't contain his jealousy, and the feeling was like a poisonous snake that kept biting his heart, but he selectively ignored it.

I am a teacher, I am concerned about the learning of students, I am in charge, what am I afraid of?

The-for-tat clash didn't last long, and ended with the bell ringing at the end of class.

After class, Batu came to persuade Cao Wu not to be angry with Lao Ma.

Cao Wu doesn't know as much as Lao Ma, and they don't take care of it.

He's just a little weird, they don't seem to offend that guy, right? Why has that guy been very opinionated about the Black Hole Band, especially himself, since last year, and he doesn't seem to offend him, right?

However, what he doesn't know is that there is a kind of person in this world who will feel offended as long as you don't circle around him and kneel and lick him.

Let's find a chance to mention it to Principal Zheng and help Class 13 change the class teacher!

In the afternoon, Huang Lie suddenly came to the school to find Liu Jingshu and went out to meet him, Liu Jingshu came back and found Cao Wu with a serious expression, and said, "Cao Wu, my grandfather suddenly fell ill and said he wanted to see you." ”

"Sick, see me, what's going on?" Cao Wu was a little puzzled.

"I don't know, can you come home with me after school?"

"Okay, I'll talk to my family. ”

After school, he came to Liu Wanxiang's house with Liu Jingshu, and as soon as he entered the house, Cao Wu saw the old Yuan Tou, the old coppersmith who Liu Wanxiang entrusted him to make live cores.

Old Yuan Tou was sitting in the living room and smoking, when he saw Cao Wu coming in, he hurriedly got up and said, "Xiao Cao, it's good that you're here, you have to believe me, this matter has nothing to do with me." ”

"What the hell is going on?"

Huang Lie's kid was a stuffy gourd, and he didn't say it clearly, and Liu Jingshu didn't know what the situation was, only that his grandfather suddenly fell ill, and he was anxious to see Cao Wu.

Old Yuan Tou sighed, pointed to the bedroom and said, "You still have to ask Lao Liu!"

In the bedroom, Liu Wanxiang was lying on the bed with a towel on his head, and when he saw Cao Wu and Liu Jingshu coming in, he struggled to sit up.

Cao Wu hurriedly stepped forward to help him, and asked, "What's wrong with you?"

"Xiao Cao, I can't help you!" Liu Wanxiang grabbed his arm, ashamed: "I didn't do what you asked me to help do, what can I do?"

"Don't worry, you say slowly, what's going on?"

"The patent for the suona live core has been applied!"

"Requested?"

Cao Wu was stunned for a moment, and then wondered a little, Liu Wanxiang had checked in advance and determined that there was no live core in the patent for suona accessories, and there was no such thing in the world, so he would want to help him apply for a patent, but now he was suddenly applied, there must be something wrong with it.

"Have you seen who the applicant is?" Cao Wu asked, could it be Mr. Guo who appeared?

"I saw it, it's ......" Liu Wanxiang suddenly felt a little embarrassed, he gritted his teeth, or said: "It's Guan Zhijun, I asked Lao Yuan Toutuo to ask him about the suona live core, he is the president of the Civic Music Association, and he visited Istanbul, so I thought of asking him, but I didn't expect ......"

Cao Wu frowned, in fact, he didn't care too much about all the invention patents, as long as he could bring Mr. Guo's hard work back to life.

But if it was because of him that this patent fell into the hands of a thief who sold his reputation, then he would never allow it.

I still blame myself, I didn't pay too much attention to this matter, so I would be taken advantage of by the villain.

"You don't blame you for this, you relax, your body matters. Cao Wu comforted.

Hearing him say this, Liu Wanxiang was even more upset, smashed the fist bed hatefully, and regretted: "It's all my fault! I knew that it would definitely be wrong if I didn't issue the certificate for so long, but I never thought that the patent could be stolen!"

Cao Wu comforted him, but also some doubts, the patent office is a national institution, the management is quite strict, the relevant processes are submitted by the computer system, a series of leadership reviews, and the counter is monitored everywhere, so it stands to reason that the risk of patent loss is very small.

But this is what happened, and he can only find a way to solve it.

"Don't worry, if there is a problem, we will solve it. Cao Wu thought for a moment and asked, "How did you find out that there was a problem with the patent?"

"That time, you handed me the materials before you went to Beijing, and I went to the patent office to file an application as soon as possible. However, after submission, it takes a month before the preliminary review can be conducted. ”

"I waited for a month, went over to ask, and they said that this invention needs to find more than three senior experts to come to review and evaluate, and the current suitable experts have not been found, and they need to wait for another month. ”

"I waited another month, and after that, they still said the same thing, and I felt that something was wrong. Yesterday, I asked someone to check it for me, but I found that the CNIPA had accepted the patent application, and it had entered the substantive examination stage, and it would be authorized in a maximum of one month, so I knew that something was wrong......

Cao Wu listened quietly, frowning and thinking, he had roughly understood that this should be someone inside the patent office.

That Guan Zhijun's energy is so great, can he actually put his hand in the patent office?

Cao Wu didn't know, but he knew that this matter had to be dealt with as soon as possible.

However, just when he asked Niu Li to help contact a lawyer for consultation, a news item was published in the major paper media in Xiangcheng, "The President of my Civil Music Association Invented the Suona Living Core, and the Millennium Musical Instrument Has Been Improved".

The article introduces in detail the structure and principle of the living core, focusing on Guan Zhijun's invention ideas, and also mentions that Guan Zhijun has applied for the Ministry of Culture's Science and Technology Progress Award, and once he wins the award, it will be a great progress in the domestic folk music industry.

You must know that in the decline of traditional paper media, the audience of paper media has become major public institutions, government departments, and folk music associations in various cities.

The folk music association, which has not had a new movement for many years, was shocked by this invention, and the suona, which has not changed greatly for thousands of years, can actually change the performance method and blow semitones, which caused no less shock in the folk music circle than the movement caused by Liu Xiang in the sports circle after Liu Xiang won the championship.

Even the Music Association took the initiative to speak out and expressed praise and support for this.

Guan Zhijun became famous.

However, Cao Wu could see from this slightly hasty report that the guy was preemptive.
