"Xiaobai, when did you learn the whistle?"

In the laboratory, Zhao Xingsheng's eyes widened, looking at Gu Xiaobai like an alien.

This kid, since he participated in the primary selection of the school song competition more than a month ago, has only been a long time, and he has already rushed towards the strongest male vocal.

Although Gu Xiaobai's alto has evolved enough to beat most of the alto singers, Gu Xiaobai's high vocal range is the most gorgeous, powerful, and shocking.

Zhao Xingsheng will never forget the first time he heard Gu Xiaobai soaring high notes, and Gu Xiaobai soared directly to C6.

But compared with Gu Xiaobai's direct whistle G7 this time, he almost touched C8 at the highest, compared with the highest whistle of this piano keyboard, Gu Xiaobai is two octaves higher!

Is this still human?

Of course, the way of vocalization is different, two octaves higher cannot be simply superimposed, and it is impossible for humans to produce such a high voice with their vocal cords......

But......

Where did Xiaobai learn?

When did you learn it?

Gu Xiaobai smiled, and then Zhao Xingsheng saw the books in front of Gu Xiaobai.

Introduction to Modern Acoustics, Applied Acoustics, Physical Acoustics......

Suddenly something seemed to be understood.

But I can't believe it, wait, isn't it......

"I saw the sound principle of the organ whistle pipe two days ago, and found that it was all in a single-ended closed tube, and the air flow hit the edge edge of the sound, so I tried it......" Gu Xiaobai said.

And then ...... Just learned?" Zhao Xingsheng was at a loss.

"No, I've been practicing for a long time. Gu Xiaobai said.

You've been here for a long time, how long?

Zhao Xingsheng didn't want to ask at all.

He felt that every time he was with Gu Xiaobai, he would be hit.

Even if you're a top student, you're too much!

Then, Zhao Xingsheng saw the thick stack of books in front of Gu Xiaobai, and suddenly realized a problem:

Could it be that I can't sing well because I haven't learned acoustics well?

No, I just overthought it...... No matter how good my acoustics are, I can't sing like this!

Zhao Xingsheng was crazy, chaotic, and crazy.

The system is at the bottom level, sighing deeply, and deleting the "super high range vocal skills" in the follow-up rewards, so far, except for the "upper vocal range +8" and "primary vocal skills", he has not sent out any of the other vocal skill rewards, and they have all been deleted by himself......

Other people's systems will release a task if they are fine, rewarding this skill and that skill.

The host is happy, and the system is happy.

But what about his host? This hasn't taught anything, and he's almost running through the question bank.

He's exhausted.

Why? Why?

Mom, what kind of difficulty did I choose, am I hell?

No, you can't develop in the field of vocal music anymore......

You have to change the direction, is it a variety of instruments, or is it ......

Wait, haven't you been hyping this lately? The system suddenly had an idea.

Over there, Zhao Xingsheng decided to end the topic: "Xiaobai, I heard that you plan to take the graduate exam?"

"Hmm...... It's going to be a test this week. Gu Xiaobai continued to look down at the book.

"Have faith? Wait...... What? There's an exam this week?"

Isn't it the next school year?

"Hmm......" Gu Xiaobai said.

Dongyuan University has a three-semester system for undergraduate students, and there are various internships and practical courses every summer, which is much less than the summer vacation at other schools.

And the master's students of Dongyuan University...... Fewer holidays.

Other schools, if they hadn't been caught by their mentors, they would probably have been on vacation at this time, but the graduate students of Dongyuan University have just reached the middle of the exam season, and now is the time to be sour.

A few days ago, Senior Xia Cong called Gu Xiaobai and said that his tutor brought "Introduction to Modern Acoustics" and "Applied Acoustics", and he also asked another tutor with "Physical Acoustics", who could accept Gu Xiaobai to take the exam this year.

Zhao Xingsheng was puzzled: "If you take the exam this year, what about the class hours and attendance?"

The two teachers said that they could make up for it after the school hours, and they could just take the time to make up for it during the summer vacation. Gu Xiaobai said.

"Is this okay?" Zhao Xingsheng always felt that there was something in the middle, let students take the exam, and then make up for the time, not that it could not be operated, but to fill out a complex form to apply to the school, and the general teacher was too late to excuse himself......

Zhao Xingsheng scratched his chin, thoughtful, and then asked, "When is the exam?"

"Tomorrow, the day after tomorrow and Saturday. Gu Xiaobai said, "Just before the start of the summer semester, end the exam." ”

After Gu Xiaobai sang the chanting version of "Yanyan" last time, he still didn't reach the resonance level that could start the trial.

However, Gu Xiaobai no longer has time to go to the wedding, so he can only put these things aside for the time being and focus on his studies.

After all, Gu Xiaobai has to take three acoustic-related courses in a row!

As he was talking, Gu Xiaobai's stomach gurgled and it was almost noon again.

Gu Xiaobai's brain is like an 8-cylinder engine, with super high energy consumption and fast hunger.

"Alas, I miss Senior Brother Xiao Su so much......" Whenever he is hungry, he has to sigh.

After Senior Brother Xiao Su left, no one gave him food in the laboratory.

"I miss him too, and now I don't have any coolies to use...... Luckily, I recruited another graduate student. Zhao Xingsheng spoke like a negative scumbag.

Gu Xiaobai felt that it was not worth it for Senior Brother Xiao Su for a second.

"Okay, hold on a little longer, and then go to the cafeteria to eat and sing!" Zhao Xingsheng said.

Gu Xiaobai sings in the cafeteria every day, and unless he conflicts with his studies or leaves school, he can't move.

But it's definitely a good habit, and it's better to go to the cafeteria every day to eat and sing than to be bored in the lab all the time to review.

"...... on the Internet" Zhao Xingsheng wanted to ask Gu Xiaobai's opinion on the development of things on the Internet, but after saying half a sentence, he paused again: "Forget it, you can study." ”

Gu Xiaobai didn't care about this.

On the Internet, Ji Bai has a new moth.

The definition and rights protection of plagiarism is a protracted and thankless task, and Gu Xiaobai doesn't seem to care too much about the so-called plagiarism, after all, Zhao Xingsheng knows that Gu Xiaobai does not regard "Yanyan" as his original.

But Ji Baici became more and more arrogant, and publicly announced on the Internet that he wanted to write songs with Gu Xiaobai.

"I participated in the 'Light Wheel Project' original singer competition in Yuncun, Gu Xiaobai, if you have the guts, dare to come and write songs with me?

Zhao Xingsheng felt that Ji Baiju probably received an advertisement for Yuncun's 'Light Wheel Plan', and used Ji Bai to promote his 'Light Wheel Plan', and wanted to fool Gu Xiaobai over.

But...... Never mind.

Jumping clowns, ignore it.

If any cat or dog shouts in the air, Gu Xiaobai has to agree, won't there be even time to study?

......

At one o'clock in the afternoon, in front of the laboratory building of the Department of Physics, two middle-aged professors and Xia Cong got together.

A slightly bald professor said: "Xiao Xia, how is Xiao Bai's revision? The exam is tomorrow, you contact Xiao Bai, let's find a place to answer Xiao Bai's questions." ”

"Yes, whether you can deceive Xiaobai depends on today, ......

The other, bald-headed, let out a villainous laugh.
