Datang: The prince of salted fish was overheard by Li Er

Li Yougang was about to sit down and have a chat with the teachers, when Sakura came to report that His Majesty was coming.

[What is Li Erlai doing!The start of school today is messy enough, and he's here to add to it. 】

Although he had some opinions in his heart, the arrival of Li Shimin made Li You leave the teacher's office and come to the living room.

"My son, I have met my father, the elder brother of the prince."

This time, Li Shimin also came with Li Chengqian.

During the recent period, Li Chengqian's performance was as good as ever, which made Li Shimin very happy.

After the court today, Li Shimin took Li Chengqian to watch the fun again.

"You'er, you don't need to be too polite. We're going on tour in low clothes, so just pretend we don't exist, and we'll just watch the ceremony in the corner."

Hearing what Li Shimin said, Li You felt relieved.

Soon, the opening ceremony was ready, and the students also entered the school playground in an orderly manner.

And in the stands on the side of the playground, there are the parents of the students who are sitting and watching the ceremony this time.

When Li Shimin quietly appeared in a corner of the stands, he found many familiar faces.

"Wuji, you're here too. Huh? Xuanling, Keming, why are you two here?"

"Aren't all of your children not on the enrollment list?"

Li Shimin asked in surprise.

Fang Xuanling hurriedly said: "Return to Your Majesty, my two sons missed the exam because they were not in the capital, but Kong Jijiu said that at most half a year, new students will expand their enrollment, and they will still have a chance at that time."

"How can we not be in such a prosperous age?"

Du Ruhui: "What Xuanling said is absolutely true!"

In fact, these two people were just curious. Li You had brought them too many surprises in the recent period.

In addition to the already well-known salt prison in Chang'an, Li You's shadow was also found in the big change of blood at Honglu Temple, flood control in Guanzhong, and the education reform of Guozijian.

Especially Kong Yingda's attitude towards Li You that day surprised them even more.

So today they all mixed in.

After all 82 students and Princess Changle entered the arena, Li You stepped onto the temporary stage.

After playing, Li You glanced at the audience, but saw many different emotions.

There are those who look forward to it like Li Anren and Feng Baobao, those who are curious like the Cheng brothers, and those who are as affectionate as Changsun Siyi.

Of course, apart from these, more people still look nervous. They think this is a new opportunity, but they don't know what kind of touch it is.

In the end, Li You noticed some unusual expressions.

He understood that there must be descendants of aristocratic families among the 82 students today, and Li You had expected that these people would come to Xinxue to make trouble.

But there were a few people who looked like they were watching the show, and Li You suddenly thought that perhaps today's opening ceremony would not end so peacefully.

Thinking of this, he glanced at the school gate, and immediately saw a few sneaky people looking around.

【Hmph, you still want to make trouble. If the elites from Shence Mansion and Jinyiwei hadn't gone to Hexi, I'll arrest you all! 】

Although he knew that someone might make trouble, Li You didn't panic at all and walked out.

"Good morning, classmates."

Li You's voice was not loud, but it was strange that everyone present could hear it very clearly.

"I know that many of you have no concept of new learning, and you don't know what you are here to learn."

"Actually, I can't tell you this question. What I teach here is the basic knowledge. What kind of height you can reach depends entirely on you."

"You are the first batch of students. You will study for half a year. After half a year, if you want to go back to the second hall and the sixth school, I will never stop you."

"In addition, Xinxue also belongs to the Imperial Academy, so students don't have to worry about the future."

After Li You finished speaking, he immediately dispelled many people's doubts.

It's only half a year, even if you haven't learned anything in the new school, it's not too wasteful.

After Li You finished speaking, he asked Kong Yingda, the Guozijian Jijiu, to speak on stage.

After Kong Yingda came to the stage, he said with a smile: "I'm very happy, you are all here today!"

There was nothing wrong with the content of this sentence, but after he finished speaking, Kong Yingda was slightly taken aback.

Compared with Li You just now, Kong Yingda's voice was too low.

Kong Yingda thought it was because the venue was too big, so he opened his voice and said, "I have high hopes for Xinxue, and I hope you will work as hard here as before."

This time, Kong Yingda had raised his voice to the highest level, but it still couldn't compare with Li You's voice just now.

At this moment, Kong Yingda stopped in embarrassment.

He still has a lot of things to say, but if he keeps shouting like this, he feels that he can't bear it.

Li You, who was in the audience, saw Kong Yingda's embarrassment, and hurriedly stepped onto the stage, pulled Kong Yingda to the rear right, and said in a low voice.

"Kong Jijiu, stand in this position and speak, so you don't have to use so much force!"

Kong Yingda looked down and drew a circle on the ground, which was obviously Li You's mark.

Although a little confused, Kong Yingda tried to use her usual class voice.

Sure enough, this time he used the same voice, but the effect was completely different.

The sharp-eyed things in the audience saw the change of position just now, and they were immediately curious.

After Kong Yingda's speech, Li You came to the stage to introduce the courses and future teachers one by one.

Finally, Li You asked: "Everyone, do you have any questions? No problem, everyone will start preparing for class!"

At this time, the sharp-eyed classmate immediately asked, "His Royal Highness, when Kong Jijiu was speaking just now, his voice was very low at first, but I saw that you adjusted his position and his voice became louder."

"That is why ah?"

Hearing this classmate's words, the other students also thought of what happened just now, and immediately began to whisper in the audience.

"Yes, I noticed it just now, and I thought I had heard it wrong."

"This thing is amazing, is it Taoism?"

"My father said that it is very likely that the King of Chu was taught by an immortal to have such a big change."

Li You signaled everyone to be quiet, and then said: "Everyone don't need to think too much, this question is actually not difficult."

"Have you seen the drums around the playground and on my stage?"

"It's the drums that are the reason!"

"These drums are not actually for beating, but for amplifying sound."

"And the principle of sound amplification is one of the things you will learn in the new school in the future."

These drumheads are smooth enough to echo better.

Therefore, these big drums are placed on the playground and on the stage, and the sound waves of the people on the stage are transmitted to the drum surface for rebound, and the sound will continuously fluctuate back and forth in the drum surface.

In this way, the more it spreads, the more students below can hear it clearly.

Of course, because of the angle of the sound waves, only specific locations can exert the effect of sound amplification.

As soon as Li You said this, there was another uproar below.

None of these students thought that they would learn something like Taoism in the new school.
