Outside the lecture hall of the university, a bus with black windows was parked not far below the steps.

At this time, from the modified exhaust window on the top of the bus, a stream of gas was rushing out, making a whirring sound. In the air intake on the other side, the shutters had been opened to the maximum, and there was a hissing sound of air intake.

Like a poisonous snake spitting a letter.

But none of this can compare to the sound coming from inside the bus.

Its sound is constantly changing, the sound is even and delicate, like the sound made by holding a hand over fine sandpaper, but it also seems like there is a melody inside that changes periodically.

Next to it, Jiang Wei led several security personnel to pull out the cordon. A group of people stood outside the three-meter line, like a group of geese that were killed at the first glance. They all stretched out their necks, tilted their ears, and asked.

Listen attentively in the same posture.

Just like an experienced driver can judge the speed of the vehicle by listening to the sound of the engine and know whether he should jump out of the car, an experienced astronaut can basically make a basic judgment about the engine as long as he hears the sound of the engine.

At this time, this sound dazzled many people.

"The sound quality is really good, smooth, stable and delicate. If this engine is installed on something, it will be very smooth and comfortable..." A professor who works on NVH was dazzled by the sound.

"What kind of thing can be mounted on such a small engine? It can't even push a helicopter!" This is a pragmatic party.

"Flying car?" This is a curious baby.

"It's a single-soldier aircraft." It's a bit related.

"That stuff is all nonsense and is of no use now." This is to deny the pessimist party.

"You say that again to 'Master Yun'?" someone said.

"I don't think this thing needs to be mounted on anything. If I get one, I will tie it to my bedside and listen to the sound and sleep well..." He Shisong quickly changed the subject.

Nowadays, Master Yun is still a taboo subject.

He was 100% sure that "Master Yun" was definitely related to Gu Xiaobai, but this child could appear in different places at the same time as "Master Yun", which made He Shisong himself a little confused.

But as soon as these words came out, everyone nodded.

"This engine really has a novice style..."

Whether it is reducing the noise emitted by propellers, reducing the probability of underwater ships being discovered, interfering with marine life, or other noise control research, it all belongs to a specialized discipline - noise and vibration control.

It is a very important subject in the industrial field.

This involves a "sound quality" issue.

For humans, even noise has different qualities and brings completely different negative feelings to people.

There are even some noises that can bring people pleasant enjoyment. For example, the roar of a high-displacement engine can make many people's adrenaline levels soar, making them want to hear it again, like an addiction.

An excellent engine runs smoothly, has a consistent sound, and provides instant feedback to the driver. It is a very important part of the driving experience, so many people find it difficult to drive electric vehicles.

Many people say that in a high-end car, even the sound of closing the door sounds high-end, which is also an important manifestation of "sound quality".

To put it simply, the field of sound quality is divided into three levels.

The first level reduces the sound level and eliminates abnormal noise and abnormal vibration.

The second level improves the sound quality.

The third level is to design the "sound DNA" unique to each brand.

In other words, when you hear the sound, you will know which company's product it is.

The engines created by Gu Xiaobai, whether in water or in the air, have the complete brand of Xiaobai and have the properties of "instrumental instruments".

Just from the sound quality of the engine, it has been achieved to the extreme.

After all, this was Gu Xiaobai’s original major.

As a musician with extremely sensitive hearing, if the sound quality is not good, Gu Xiaobai himself is afraid that he will go crazy.

Moreover, Gu Xiaobai went one step further on the basis of improving quality.

"This engine sounds like Xiaobai's handiwork. Maybe one day Xiaobai can use it to play other music." This is an expert in ship power. He is the first person who has ever seen Gu Xiaobai.

The propeller produced by the "Black Square Formula".

At different rotational speeds, the propellers produced by the black square formula emit sounds of different frequencies, as soft as humming. In the sea, they can even attract whales to follow them.

The Chinese scientists craned their necks and shook their heads when they heard it. It was only in the testing stage, and it was already making people think a lot.

Many of them have already begun to get close to He Shisong, but Gu Xiaobai can't reach them. If they build a good relationship with He Shisong, they might even be able to touch this mini turbofan.

Next to them, experts accompanying KAI and researchers from local universities wanted to put their necks together, make a long neck, and stick their heads to the window.

How come such a good thing doesn’t belong to us!

What method should be used to keep Gu Xiaobai in Korea for research?

Can our university attract Gu Xiaobai with a teaching position?

He Shisong is thinking about asking Xiaobai to dismantle his precious helicopter after returning!

Dismantle it immediately! Dismantle it immediately!

After dismantling it, I immediately started researching the new turboshaft engine with Xiaobai!

Isn’t it a waste to use such a good thing on such a mini turbofan?!

Everyone had their own ideas, and the discussion was lively outside the bus.

Then the question comes again: "What will Xiaobai put this thing on?"

They didn't know that Gu Xiaobai himself was also struggling.

Now that the engine is built, what should it be installed on?

At this moment, Gu Xiaobai's cell phone rang.

The call was from Hao Fanbai.

Just like every kid who gets high and gets a phone call, Gu Xiaobai's first reaction is: "You are so annoying..."

It's so annoying to be on the phone while I'm testing new toys!

Hao Fanbai is used to it. When did I call you and it didn’t bother you?

I help you govern the country, help you hold concerts, help you travel through time and space, and I want to report something to you. Do you still find me annoying?

"You still think I'm annoying, why don't you care about the Hua Liu concert?"

"No matter what, just take responsibility." Gu Xiaobai was about to hang up the phone.

"It seems that Sir, you have enough money to buy aircraft, enough money to do physics experiments, and enough money to make toys. You don't need me to help you make money in the future?" Hao Fanbai did not hesitate to expose the scars.

Gu Xiaobai took a look at his car.

Some people may not believe it, because it is a special material and ultra-high-precision processing. Gu Xiaobai was in a hurry. The parts of this car cost tens of millions in total.

Not to mention the manpower and material resources spent coordinating these materials and processing equipment.

If it weren't for Gu Xiaobai, anyone else wouldn't be able to get it if they had the money.

"What do you want me to do?" Gu Xiaobai was reluctant.

"I'm short of someone to sing the finale, come and sing a song."

"No!" Gu Xiaobai shook his head repeatedly.

Are you kidding me? I don’t want to go singing! I haven’t finished playing with my toys yet!

"Then help me make up a song!" Hao Fanbai said, "I'll find someone to sing it."

"...Okay...what song?" Gu Xiaobai resisted and felt aggrieved.

""The Lord in the Clouds"."

"Ah?" Gu Xiaobai suddenly thought of the witch who missed Tao Zi, "No!"

Hey, this guy actually came after him?

"Then you can sing a song casually." Hao Fan said calmly, "With you here, I won't worry about being overwhelmed."

"Then... I can just make it up casually." Gu Xiaobai gave in.

"Young master is wise!" Hao Fanbai flattered him gently.

How did a generation of wise ministers subjugate a tyrant?
