"Mother, my son has gone to school."

When he went to the study room door and learned that his mother and concubines would not enter the classroom with him, the eldest prince breathed a sigh of relief, bowed hastily, and then turned around and walked towards the classroom.

At first, he took about ten steps briskly and freely, showing eagerness to try. But as he got closer to the classroom, he gradually became hesitant. After all, he had never seen a "bad guy" in his entire life.

Thinking of the hatred that the masters had for him and the fierce look on Jiao Shun's face, the eldest prince swallowed unconsciously. If he hadn't thought of the queen and Concubine Wu watching him from behind, he wouldn't have hesitated in the last few steps.

how long.

Watching the eldest prince bravely enter the classroom step by step, the queen couldn't help but cover her mouth and smile.

But Concubine Wu next to her couldn't help but laugh.

Along the way, she tried several times to persuade her son to be careful in his words and actions, but she was worried that it was in front of the queen, so she hesitated and missed the last opportunity.

If the son is bewitched by those Confucian scholars and disrespects Jiao Shun in the study in front of the Queen, or even denies the New Deal...

Thinking that the emperor was not yet fully awake, she kept chanting the words "New Deal". Concubine Wu could not imagine how he would react when these words were heard in the emperor's ears!

"Sister, sister?"

Worried, Concubine Wu suddenly started to walk around. It wasn't until the Queen called her again and again that she realized what she was doing and said hurriedly: "What are your orders, Your Majesty?"

"You, you."

The queen shook her head helplessly, and immediately took the initiative to hold her ex-wife's hand and said: "Let's go to the room next to us to have a rest - I have already made arrangements. Someone will relay to us everything said and done in class later."

After a pause, he leaned close to Concubine Wu and whispered in Concubine Wu's ear: "If there is any childish talk, you and I can cover it up for him."

"Empress?!"

Concubine Wu looked at the queen in surprise, and the queen also smiled and immediately pulled her to the classroom next to her.

The words are divided into two parts.

But when the young prince came in, he saw Jiao Shun sitting at the desk playing with the Four Treasures of the Study. Except that he looked a little more fierce, he seemed to be no different from other teachers, and he felt bold at the moment.

So when Jiao Shun stood up to greet him, he first called Master Jiao, and then without waiting for Jiao Shun to return the courtesy, he rushed to say: "I dare to ask Master Jiao, this engineering science may lead people to be good and know etiquette.

Mingzhi?"

He has obviously memorized this question by heart, and talking about it is as crisp and refreshing as fried beans.

Jiao Shun couldn't help but burst into laughter when he saw this little guy looking menacing and trying to intimidate him, and he felt a lot more relaxed.

He was only afraid of meeting an ignorant child who could not explain his reasoning clearly. Now he saw that although the eldest prince was young, he was obviously more precocious than the children of ordinary families. In fact, he had exactly what he wanted.

He then smiled and said: "Of course. Your Highness, have you ever heard that 'A solid warehouse will tell you etiquette, and having enough food and clothing will tell you honor and disgrace'? If you learn engineering, you can guide the craftsmen to build better farm tools and weave cheaper and more durable fabrics.

When everyone is rich, they will naturally know etiquette and honor and disgrace - this is something that has been recognized by scholars for thousands of years."

After all, he is a six-year-old child, so he seems to understand these words, but since it is a truth recognized by scholars...

Xu Yao scratched his head and subconsciously turned around to look at a certain relative.

Seeing this, Jiao Shun also looked at the eunuch playfully.

Facing the two looks, the eunuch was obviously a little flustered. He hesitated for a long time, and finally nodded. After all, this is indeed a truth recognized by scholars for thousands of years, and he can't deny it casually.

Seeing his companion nodding in approval, the little guy was obviously a little discouraged, but he quickly regained his composure and said, "Master Jiao, this engineering..."

"Wait a minute."

Jiao Shun raised his hand with a smile and said: "Your Highness has already asked me a question, can I also ask your Highness a question?"

Xu Yao blinked his eyes in surprise, not expecting that Jiao Shun would ask him back, but after hesitating for a moment, he felt that it was fair for one person to ask a question, so he nodded and said, "Then ask."

Then he added: "It can't be too difficult!"

"It's just a simple question."

Jiao Shun's smile became warmer and warmer, and he raised his hand to signal the eldest prince to sit down at the exclusive small table. Seeing this, the companion who had been watched by the two people hurriedly put aside some enlightenment reading materials such as the Four Treasures of the Study and the Three-Character Classic.

Jiao Shun picked up a piece of paper and asked in a casual chatter: "I heard that His Highness is practicing calligraphy recently?"

Xu Yao lifted his chest and said proudly: "I started practicing last year. When I first came to study at the beginning of the year, the masters all praised me for my good writing."

"In that case..."

Jiao Shun put the paper in his hand in front of him and said, "Then please write on both sides of this paper with just one stroke."

"ah?!"

The little guy who had already picked up the pen and wanted to show off his skills was immediately dumbfounded. He looked at Jiao Shun first, then turned the paper over and over again, and finally hesitantly started to try to draw on it. Naturally, he failed without any surprise.

.

"Master Jiao."

At this time, the accompanying eunuch couldn't help but protested: "Aren't you making things difficult for His Highness? How could this be written on both sides?"

"Is this difficult?"

Jiao Shun pretended to be surprised and asked: "Could it be that other ministers can't do it?"

The accompanying eunuch was not stupid at all, and saw that he must have something to hold on to, but he would rather die thinking about it for a long time than he could think of a way to write it on both sides.

At this time, Prince Yao raised his hand and tugged on his sleeve, and asked curiously: "Can other masters also not be able to do it?"

"this……"

The accompanying eunuch looked at Jiao Shun, then at Prince Yao next to him, and said hesitantly: "Maybe, maybe not."

When Prince Yao heard this, he immediately threw away his brush: "I'm just telling you! Master Jiao is lying. Even other masters can't do it, and you still say it's a simple question!"

"Haha, but this question is really simple."

Jiao Shun laughed, picked up the paper used by Prince Yao, tore off a strip from the edge, took the paste that had been prepared by someone earlier, twisted the paper into a figure-eight shape, and glued a Möbius strip on it.

Then, under the incomprehensible gazes of everyone in the room, he picked up the brush and slowly drew an ink line on it, connecting the head and the tail.

At first, everyone didn't understand its meaning, but when they found out that the line ended up looking end to end, they couldn't help but burst into an uproar.

Because he was the closest, he could clearly see that the ink stain actually penetrated both sides. He opened his mouth in disbelief, and then subconsciously reached out to take it and take a closer look.

But Prince Yao was faster than him. He grabbed the Möbius strip with his hands, looked at it over and over for a while, and then drew a new one next to it with his pen. Seeing that it was the same as Jiao Shun's, he clapped his hands and cheered: "

Interesting, interesting! It turns out to be really simple! When I get back, I will definitely write it to my mother and concubine!"

The accompanying eunuch finally got the chance. He carefully held the paper ring and looked over it several times. He raised his head and said in confusion: "Here, how is this done?"

"hehe……"

Jiao Shun gave him an enigmatic smile. He seemed to have everything in his mind, but he didn't bother to explain it. In fact, he only knew that there was a Möbius strip, but how could he know the principle behind it?

But this doesn't stop him from continuing to pretend.

Jiao Shun stretched out his hand to pass the Möbius strip, and ordered someone to fetch a pair of scissors. Under everyone's inexplicably expectant eyes, he folded the paper ring in half, first cut a small opening, and then covered the original center strip.

The ink line was cut.

While cutting, he asked: "Your Highness, what do you think this paper ring will look like after I finish cutting it?"

"this……"

Prince Yao tilted his head and thought for a while, then looked at the accompanying eunuch again, obviously relying on him very much.

The accompanying eunuch thought that it would probably turn into two circles, but with the previous lessons, he felt that things would definitely not be that simple, so he dared not make any more lies and could only avoid the expectant gaze of Prince Yao.

When Prince Yao saw this, he could only guess: "I think it should be two circles, right?"

"hehe……"

Jiao Shun smiled slightly and immediately increased the speed of his hands. Soon the Möbius strip was cut in the middle. Then he shook it slightly and saw that the original paper ring did not split into two, but the diameter of

doubled in size.

Everyone in the room was in an uproar again, and the boy who was studying with him even widened his eyes.

The prince was only half-understood, so he clapped his hands and said with a smile: "It's fun, it's fun, I want to try it too!"

Jiao Shun naturally followed the good advice and guided him to repeat the performance.

Seeing that Prince Yao also successfully cut the small ring into a large ring, the accompanying eunuch couldn't help but secretly rejoice. Fortunately, he didn't question this as a cover-up, otherwise he would have made a fool of himself on the spot.

But how could this happen?

It's obviously just ordinary rice paper, just stuck together, so why...

At this time, Jiao Shun directed Prince Yao to cut the enlarged paper ring in the middle again. This time, as Prince Yao shook it off for the last time, the paper ring was finally divided into two.

Seeing that common sense had finally returned, the accompanying eunuch breathed a sigh of relief when he saw Prince Yao lifting one of the paper rings up, and the other paper ring was also pulled up at the same time. Only then did he realize that the two paper rings

They are actually set together!

"This, this, this..."

The accompanying eunuch could not help but be dumbfounded again.

Prince Yao was still unfinished and repeated the operation just now. Finally, holding four circles, he raised his head and asked hopefully: "Master Jiao, is there anything else fun?"

At this time, why does he care about showing off his power?

I have long forgotten all the teachings that those Confucian masters have given me over the past few days!

Jiao Shun smiled calmly: "Yes."

…………

In the classroom next door.

The queen held two paper rings connected together and marveled: "I don't know where he learned it from. It's just a piece of paper and he can come up with so many stories."

Although Concubine Wu couldn't figure out what the Möbius strip was all about, her mind was not on it and she was too lazy to think about it.

At this time, another eunuch trotted in and bowed to report: "Your Majesty, Mr. Jiao covered the cup filled with water with paper, and then turned it upside down so that no water leaked. Even if he pierced the paper with a toothpick, only a little leaked out.

"

When the queen heard this, she enthusiastically ordered: "Go get some water and ask for some toothpicks."

When everything was ready, the eunuch was kneeling down to explain the specific steps in detail. Another eunuch walked in quickly and said: "Master Jiao used a few drops of water to connect the three broken toothpicks into a pattern!"

After another moment...

"Master Jiao put a rubber pipe into the bucket, and the water in the bucket crawled out along the pipe!"

The Queen was dazzled by all the novel things, but Concubine Wu gradually frowned. While the Queen was just using drops of water to make the bent toothpicks into a star shape, she couldn't help but ask: "These wonderful and ingenious tricks."

It’s interesting, but what’s the point of learning it?”

The Queen was about to take over the rubber water pipe, but the movement of her hand froze upon hearing this, and then she raised her voice and asked, "What is Mr. Jiao doing now?"

One of the palace maids hurriedly went out to investigate, and soon reported back: "I'm reporting to you, when Master Jiao came in the morning, he had someone dig a big hole near the upper study room, and now he's leading His Highness there."

The queen immediately stood up and called to Concubine Wu: "Let's go and have a look."

"this……"

Concubine Wu stood up slowly, but there was hesitation in her eyebrows.

"Don't you, sister, want to know what's the use of learning these things? When you meet Mr. Jiao, you can ask him yourself."

With that said, he picked up Concubine Wu and walked out.

When they looked around the big pit like stars holding the moon, they saw a few rough eunuchs pouring some kind of viscous liquid into it one bucket after another.

Seeing the queen and concubine arriving, everyone hurried to pay their respects.

Only Prince Yao came forward happily, grabbed one with one hand and said: "Mother, mother, come and see, Master Jiao said that he has a way to walk over here without sinking or getting stuck.

"

Because he was the only child in the palace and was burdened with too many expectations, Prince Yao was like a little adult who had been controlled since he was a child. He rarely behaved in such a rude manner, which shows that he had a great time 'learning' in this class.

The queen smiled and touched his nose and said, "Why don't I see you so happy during class?"

"Well……"

Prince Yao was immediately embarrassed.

Fortunately, the queen just made a joke and immediately pulled him and said: "Then let's take a look and see how Master Jiao does it."

After the queen had spoken, Jiao pointed to the large hole that had been filled and said, "Who wants to give it a try first?"

Everyone looked at me and I looked at you, but in the end it was the accompanying eunuch who gritted his teeth and stood up.

It's said to be a big pit, but it's actually only two meters long, half a meter wide, and about a foot deep. Now it's filled with paste, and at first glance it looks like a huge pancake spread out on the ground.

The accompanying eunuch stepped forward cautiously, and first tried it with his toes. As expected, it sank in, and it took a lot of effort to pull it out.

With a slightly bitter look on his face, he looked back at the expectant Queen and Prince, but he could only step into the pit head-on.

As a result, he sank in at the first step, and his feet sank deeper and deeper. Finally, with the help of others, he was able to escape by throwing away his boots.

The queen couldn't help laughing when she saw this, and everyone couldn't help laughing, and then they all looked at Jiao Shun.

Jiao Shunchong raised his hand to the Queen, stood at the edge of the pit without hesitation, and then ran over the mucus as if he were walking on flat ground.

"Is it really over?"

"How come?!"

"I just touched it with my hands and it was all stuck in!"

Everyone was in an uproar for who knows how many times. Even Concubine Wu couldn't help but widen her beautiful eyes when she saw this scene with her own eyes.

"Master Jiao, teach me, teach me!"

As usual, Prince Yao was the first to come to his senses and ran and jumped over to urge Jiao Shun to teach him the secret.

Jiao Shun smiled and said: "Your Highness just needs to relax and run over from above. Remember not to stop in the middle."

After various novel little experiments, Prince Yao was now very convinced of him, and turned around and rushed towards the big pit without saying a word.

"Your Highness, be careful!"

"Be careful!"

Amidst the exclamations of everyone, they saw that Prince Yao also walked on flat ground and easily passed through those large sticky pits.

"What's going on..."

Just when Prince Yao wanted to ask about the principle again, Concubine Wu suddenly questioned: "Master Jiao, if you learn these tricks, what good will it do to your highness, the court, and the country?"
