Chapter 737
After getting off the bicycle, the craftsman quickly came over and asked, "Ma'am, how did you manage to ride on two wheels? How did you manage to control it with one hand? Is there any trick to riding this?"

Yun Yiyi was asked these three times, and she was a little confused: "Wait, come one by one."

"Ma'am, why can this bicycle walk on two wheels? And it won't fall down when riding it?" The craftsman thought for a while and raised this question first.

This is the most confusing point for craftsmen. How can the two wheels not fall over?
He was puzzled.

Yun Yiyi was immediately at a loss for words.

Why the bicycle does not fall down is still an unsolved problem even in modern times!

Scientists of all dynasties have studied it for hundreds of years, but so far no one can perfectly explain this problem.

There are some possibilities.

One is the gyroscopic effect, which most people agree with. It says that when the front wheel of a bicycle turns, its centrifugal force will help keep itself balanced, just like when a spinning top is twitched, the top will stay around its axis. The inertia in the direction of rotation is the same.

The second is the centrifugal force effect.

The idea is that when the bicycle is tilted to one side, the rider will turn the front wheel to the same side, and because the front wheel is turned at an angle, the bicycle will travel along the circumference of the tilted side, and the centrifugal force will be outward from the circumference at this time. It will straighten the bike.

There are other points of view, and Yun Yiyi does not intend to explain them to the craftsman.

After all, according to the laws of physics and the like, the ancients would not understand them.

Yun Yiyi cleared her throat, and replied flatly: "This is a theology bestowed by God, and you and other mortals cannot discover it."

Anyway, if it doesn't make sense, it's right when it comes to theology.

The craftsman immediately looked at her with reverence. He didn't understand any theology, he only knew the first two gifts from heaven.

Since Madam said it was a gift from God, then this question can no longer be asked, as it would be blasphemy to ask again.

Then, he asked again: "Then madam, how did you manage to control it with one hand?"

The craftsman was very nervous watching from the sidelines. It was already surprising that he could ride, but it was incredible that Yun Yiyi could still control it with one hand.

Yun Yiyi sighed: "As long as the skill is deep, the iron pestle can be ground into a needle. This is very simple, and it will come naturally with more practice."

The craftsmen's admiration for her is like a surging river.

"Madam, can you teach the villain how to ride?"

"This is very simple, you first hold the front of the car, and then step on it with one leg..." Yun Yiyi said, demonstrating.

The craftsman rubbed his hands and followed the drill excitedly.

"Touch!" A loud bang hit the ground.

Yun Yiyi looked at him.

The craftsman looked innocent: "Madam, I really don't blame me, I stepped on it."

Yun Yiyi supported her forehead: "Your posture is wrong, you should step on this lightly."

As she spoke, she supported the front of the car, and lightly stepped on her right foot: "Just like this, push your left foot harder, try it."

The craftsman quickly took over the bicycle. Following Yun Yiyi's example, he stepped on his right foot first, but his left foot couldn't get out for a long time.

"Step on it." Yun Yiyi said.

The craftsman gritted his teeth: "Madam, I dare not!"

Yun Yiyi: "How can you ride if you don't get up, move faster, and then sit up."

The craftsman did some mental work for himself for a long time before stepping on it, and with a bang, he was hit by the car and fell to the ground!

"Help him up quickly." Yun Yiyi exclaimed.

The guards hurriedly lifted the car, and helped the person. Fortunately, he escaped quickly, except for some small bumps, there was no damage.

The craftsman covered his right cheek, quite embarrassed: "Madam, this is really hard to ride!"

Yun Yiyi sighed silently: "You should give up cycling, this is not suitable for you."

"Ma'am, it would be great if this wheel is a little more stable, so it won't be so small that it can't be grasped." The craftsman said distressedly.

"Stable?" Yun Yiyi suddenly had a flash of inspiration.

How do some modern children who can't ride a bicycle but want to ride a bicycle handle it?

Isn't it just installing two small wheels on the rear wheel?

Let the rear wheel have a point of support, so that it will be stable whether you can ride it or not.

Yun Yiyi hurriedly said: "Bring the paper, I figured out how to do it."

As soon as the craftsman saw her expression, he knew there was help, and hurried to the house to take out paper, pen and ink.

Yun Yiyi slowed down, took out the brush and drew the outline of the bicycle first.

"Ma'am, this has already been made." The craftsman frowned slightly.

"No hurry, let me add two more strokes." Yun Yiyi calmly dipped in ink, and added two more small wheels on both sides of the rear wheel.

After finishing the painting, she blew on the still wet ink, and then handed it to the craftsman: "Do you think it can be stabilized now?"

"Madam is really ingenious! Adding these two wheels will surely stabilize them, and let the young ones make two more wheels." The craftsman stroked his beard.

"Go." Yun Yiyi said.

As she said that, she pushed the bicycle out again, and said to the maids and guards, "Who wants to try?"

"Servant, servant wants to try." The servant girl raised her hand.

Although she was afraid of falling, she wanted to try the feeling of riding.

Yun Yiyi smiled gently: "Don't be afraid, I'll watch for you."

The servant girl nodded and bravely walked in front of the bicycle.

"This place needs to be pushed up with your feet first." Yun Yiyi pointed to a place and said, "Otherwise accidents will easily occur."

The maid clenched her fist and took a deep breath before taking the bicycle.

Yun Yiyi patted her on the shoulder: "It's okay, it's very simple, just follow my instructions."

The servant girl looked straight at her, her eyes full of trust: "I believe in madam."

"The hem of the skirt needs to be tied up first, so as not to get caught in the wheels while riding, and the clothes will be torn." Yun Yiyi's words were not alarmist.

She had seen such cases before, if she was not careful, she might overturn.

The servant girl was taken aback by these words, and quickly got up to check her binding method, and after making sure that she would not be thrown out, she looked at Yun Yiyi: "Madam, I'm ready."

"Well, you stretch out your right foot first, step on it first, don't shake your left foot, keep it steady." Yun Yiyi walked to the other side and looked at her, pointing to a position.

The servant girl stabilized her mind, followed Yun Yiyi's guidance, and stepped on it first.

"Is that so? Ma'am." The servant girl asked tentatively.

"Yes, then, you have to relax, step up with your left foot, and then sit up immediately."

Seeing that the servant girl was about to fall, Yun Yiyi hurriedly supported her to avoid a fall.

The servant girl patted her chest: "I scared the servant to death."

"It's okay, do it again, I won't let you fall." Yun Yiyi calmly withdrew her hand.

The servant girl nodded, and did it again, this time with Yun Yiyi's support, she actually sat on it.

Yun Yiyi was afraid that the seat would be too high to sit on, so she asked the craftsman to make it shorter.

"That's it, step up, don't be afraid, watch the road ahead!" Yun Yiyi slowly let go.

"Ma'am, did you see me riding?" The servant girl didn't dare to turn her head, her eyes were bulging and staring at the front, as if she was afraid of bumping into something, her whole body was stiff.

Yun Yiyi watched her ride slowly from behind: "I saw it, it doesn't matter if you slow down, pay attention to the front!"

The servant girl felt that her heart was almost in her throat, her whole body was tense, and she couldn't control her hands and feet.

"Ma'am, ma'am, where should I ride!" The servant girl almost held her breath.

"Left, look to the left, there are few people there, remember to turn the front of the car with your wrist!" Yun Yiyi trotted to the front of the servant girl to show her the way.

"Ma'am, I dare not move."

"Don't be afraid, try harder, you've already ridden a certain distance, are you still afraid of turning?" Yun Yiyi encouraged.

As soon as the servant girl heard about it, she couldn't help but look back, and when she turned her head, her wrist lost a little strength.

"Be careful! Look ahead."

The servant girl turned her head quickly, and she saw the big garden in front of her at a glance, and she was about to bump into it!
"Ma'am, why stop here!" the servant girl yelled in fright.

"Do you see the two brakes in front of the front of the car? Hold them tight, hurry up!" Yun Yiyi was afraid that she would hit her, so she called a few guards to go up, and if she hit it, she would hold the car first.

The servant girl tried her best to calm down, and with all her strength, she held the two front brakes.

And the garden was only a foot away from her, and she didn't dare to look at it, fearing that she would be bloody from being hit.

There was only a sharp friction sound, and the bicycle stopped safely.

The maid opened her eyes and saw a group of guards supporting the bicycle beside her.

"Come down, you did it." Yun Yiyi said with a smile.

The servant girl lowered her head, and saw that she was just a step away from the garden.

If it weren't for the guards supporting the bicycle, she probably fell down.

"Ma'am! This servant is scared to death!" The servant girl patted her chest in fear.

"Don't be afraid, you did a good job. Just now you held the brake tightly. If you step off with one more foot, you can get off the car. Although you only hold the brake, it is already very good to be able to do this." Yun Yiyi comforted her.

She has taken a big step and is only one step away from success.

Compared with craftsmen, she is really doing a good job.

"Look at the back, you have ridden such a long distance, there is nothing to be afraid of." Yun Yiyi encouraged her to turn her body and look at the back of the bicycle.

The maid opened her eyes wide and couldn't believe it: "Ma'am, did I really ride such a long distance?"

"If you don't believe me, ask them!" Yun Yiyi pointed at the guards.

The guards nodded sharply: "Madam is right, we have all seen it."

"Ma'am, I really did it!" The servant girl covered her face excitedly.

She turned out to be able to ride like a lady.

She didn't expect that she could ride such a long distance. This was something she had never imagined, like a dream.

"Ma'am, I want to try riding again. I was too nervous just now, and I couldn't get off the bike. This time I will definitely be able to." The servant girl let out a foul breath.

With the previous experience, she will not panic so much when she encounters obstacles this time.
