Early the next morning, the little moth was awakened by a sound of water, and saw Gu Xiaobai wading through the water to break the reeds.

"Brother Xiaobai, what are you doing?"

......Gu Xiaobai dragged a reed back to the shore with a sharp stone, and used a sharp stone to cut one end of the reed's stalk, revealing a layer of membrane inside, and then slowly twisted it, twisted the membrane into a plug, and used a straight branch to push it into it.

The membrane of the reed was ripped off the inside and pierced out from the other side.

Gu Xiaobai carefully grabbed from the other side of the reed, slowly and forcefully pulled outward, and soon, a fresh flute membrane was taken out.

Generally speaking, the flute film still needs subsequent processing and preservation, but at this time, Gu Xiaobai can't care so much.

He found a little gum from a nearby tree and glued the membrane to the flute.

There is no way, whether it is Ejiao or Bai Ji, Gu Xiaobai can't find it, so he can only make up for it.

After all this, Gu Xiaobai held the flute and gathered under the rising sun, watching happily.

Because he only had rudimentary stone tools at hand, the flute looked ugly, with a little burr around the edges, and some scorched marks remained at the end near the mouthpiece.

But this is the first time that Gu Xiaobai has made a flute with his own hands!

Bring the flute to your lips and try the tube tone first.

"Woo......" A long note came out of the flute, startling the little moth, "What...... Why is it so loud!"

Gu Xiaobai was very proud, although he didn't know what era he was in, but from the perspective of hanging the gap below him, it was estimated that it was the pre-Qin era...... Suona must not have been introduced to China yet.

Most of today's flutes are blown vertically or diagonally.

Even the flute with a flute membrane to strengthen the resonance will not appear until the Tang Dynasty.

Now that the No. 1 scoundrel of folk music is gone, of course my dizi can be the king!

With a movement of his fingers, he blew the scale, then took out the sharp stone and trimmed it slightly.

Perfect!

Now Gu Xiaobai doesn't have any tools at hand, so naturally he can't measure it directly.

But it is impossible for a physics bully to be stumped by this difficulty!

When he was making the flute last night, he tried to blow it and found the first sound hole.

After the first sound hole was made, with Gu Xiaobai's terrifying "absolute pitch" comparable to the instrument, coupled with mental arithmetic ability and flute hole formula, he accurately calculated the distance between the first sound hole and the blowing hole.

Then he used a thread removed from his clothes, and used a method similar to "finding the limit", using the original thread "half + third + quarter" to accurately determine the position of the remaining holes.

When measuring the position of other holes, Gu Xiaobai carved a line of scales on the flute by the way.

Each scale is one centimeter, and at the very end, he also carved out ten scales accurate to 1 millimeter, which is estimated to be one of the most accurate rulers of this era.

And with a precise ruler, you can measure the exact length, the length is determined, the volume is determined, the volume is determined, the mass can be determined (the mass of 1 liter of water is 1KG), the length and mass are determined, you can make accurate timekeeping (pendulum), you can accurately time, you can calculate the motion, you can calculate the motion, you can enter Newton's three laws......

Newton's three laws, are relativity and quantum mechanics still far away?

In less than two or three years, our rockets will be in the sky!

Gu Xiaobai stood by the river, holding his flute in both hands, and let out a wild laugh of "Wowhahahahaha!"

What is music? Can I eat it? Physics can make me change the world and dominate the world!

I look like I'm making a flute, but I'm actually making a ruler!

I, Gu Xiaobai, am not so easy to succumb!

How can I forget physics? Physics is my original match, and you will always be a junior in music!

Gu Xiaobai even thought about the name of the year after he became the hegemon, it was called the Physics Dynasty, as for himself, he was called the First Emperor of Physics, after becoming the emperor, both men and women, young and old, had to learn physics, take the exam once a year, and if he couldn't pass the test, he would cut off his head!

Thinking of the place of pride, Gu Xiaobai laughed.

Boom Boom Boom Boom ......Boom Guy Boom

Tyrant Gu Xiaobai is online.

Now, between Gu Xiaobai and the tyrant, only ...... is left

Started gurgling again.

Gu Xiaobai finished laughing wildly, turned around, looked at the little moth who was quietly retreating, and said, "Little moth, go, Brother Xiaobai will take you to eat fragrant and spicy food!"

A good day is beckoning!

The little moth, who had thought he was in danger, came back with a sparkle in his eyes when he heard that there was something delicious.

Gu Xiaobai took the little moth and swaggered back to the location of the bazaar, planning to use a song of Qinchuan to blow these people's liver and intestines, crying and making noise to serve food.

Then Gu Xiaobai was dumbfounded.

Under the big locust tree, two dirt roads intersect.

Under the tree, there was only one idler enjoying the coolness, staring at the two people with puffed eyes.

Other than that, there was no one in the four fields, and there was silence.

"People...... What about people?" Gu Xiaobai glared.

"Brother Xiaobai, yesterday was the ninth day of the first month, it was a set, and today it is the tenth day of the first month. The little moth said timidly.

This little girl, with her ferocity towards fish, did not leave half a cent for humans.

Gu Xiaobai: "......"

Something as old as a set...... How can Gu Xiaobai, a post-00 generation, know!

"That'...... When is the next episode?

"The ninth day of the next month. ”

Gu Xiaobai: "......"

Why is there only one episode a month?

What kind of cheating daddy era is this!

Gu Xiaobai wanted to cry.

He squatted on the ground and brushed a few questions with his memory, letting reason fill his brain, and then he held back his tears.

"Brother Xiaobai, I'm hungry ......"

Little Moth Sister, I'm hungry too......

Do you want to go back to catching fish? Roasted grasshoppers, monkeys, shrimps and crabs?

I, Gu Xiaobai, am not here, not here!

At this moment, Gu Xiaobai saw a carriage painted black coming from a distance, and there were two people holding torches in front of him.

In broad daylight, these people still have to light torches?

Gu Xiaobai felt that these people were really good at playing.

No matter what era this dream is, this is still the first car Gu Xiaobai has seen, which is even rarer than a Rolls-Royce.

A horse, a car, a royal man, and a mighty crowd of people followed.

There were men and women, old and young, and a group of children following behind, as if they were watching the excitement.

In the back of the car, there are also a few musicians, holding zhu, cymbals, small drums, flutes, and shengs, and playing music while walking.

These instruments and modern ones are plausible, and most of them are unknown to Gu Xiaobai.

The idler who was sitting under the tree saw the car coming, and immediately went up, saying auspicious words in his mouth, bowing and making gestures, begging for some food to come back, and looked at Gu Xiaobai proudly.

Gu Xiaobai looked at the idler, then at the convoy, and dragged the little moth: "Let's go, let's go over and have a look!"
