"——Okay, let's go back to the topic just now." Lou Wuchen saw that the children had gradually calmed down, so he clapped his hands and continued the lecture, "Muyu, what did I just say?"

The boy was stunned for a moment: "Teacher, teacher, he said that 'number' can describe all things..."

"Well, very good." Lou Wuchen nodded, "Do you have any questions?"

"...Teacher, I don't quite understand." Mu Yu hesitated for a moment, and then asked boldly with Lou Wuchen's encouraging eyes, "You said that everything can be described by 'numbers', but a horse is four inches

If you don’t have the vision and the measure to make a piece of cloth, how can you use numbers to describe it?”

Good! Lou Wuchen cheered to his students in his heart. This question came at the right time. The timing was so good that Lou Wuchen almost suspected that Mu Yu had asked for it himself: "This question is very interesting. We can now

Let’s give it a try—Muyu, come here, this is the ruler, hold it.”

Then, Lou Wuchen picked up a branch that he had folded outside during class and handed it to Mu Yu: "Here, use a ruler to measure it and break off two feet from this branch."

Mu Yu followed the instructions and broke off a two-foot branch and handed it back to Lou Wuchen. Lou Wuchen nodded, raised the branch and showed it to the children, "Look, everyone, this is a two-foot-long branch."

The branches——”

"—Now, I divide it into five identical parts."

Lou Wuchen snapped his fingers, and the children didn't even notice the fluctuation of spiritual energy. They saw that the branches were all broken into five pieces. Lou Wuchen put the five broken branches together and showed the neat ends to the children.

He handed it to Muyu and said, "Muyu, please measure it. How long is each section?"

"...back to teacher, four inches."

"Well, that is to say, even if there are no inches, we can still use the two 'numbers' of 'two' feet divided into 'five' parts to describe this length. Are you right?"

Seeing Mu Yu and the children nodding, Lou Wuchen continued: "Of course, in fact, the concept of inch itself is derived from 'ten' parts divided into 'ten' feet, so the length of several inches itself represents

It can be measured with a ruler..."

"What about the others? Yes

Isn’t it true that everything can be expressed by numbers? Let’s try it. Who is willing to come this time?”

After the children looked at each other for a while, several children stood up at the same time.

"Ah, it seems that everyone is getting more motivated. Not bad, let's do it one by one." Lou Wuchen asked the children to line up and let the first child stand up first, "Muyu, measure Xiaoxia's height.

.”

Mu Yu followed the words and walked towards the first child with a ruler, but then turned around with a grimace: "...Teacher, I can't measure it. It's more than four feet, but less than an inch..."

"It's okay, that's all." Lou Wuchen secretly used a magic trick to measure the child's height, which was four feet, seven minutes, six cents and nine cents, or 4.0769 feet, which means...

Lou Wuchen took out a long rope that was also prepared in advance and handed it to the children behind Xiaoxia: "Here, you take this rope, pull it straight from the soles of Xiaoxia's feet to the top of his head, and then lower it straight from the top of his head.

Repeat this thirteen times...yes, that's it, now the rope is thirteen Xiaoxia's length."

"Now, straighten the rope and measure it. You can take a few more rulers to see if the length of the rope is fifty-three feet."

The children were a little commotion, and the children in the audience also came over one after another, and started playing lively with a long rope in the large square. Some shouted at the other end that it was not straightened, and some shouted at the people around them.

Whisper to get him to align... After a while, the children's chirping discussion suddenly quieted down, and everyone turned around and looked at Lou Wuchen with surprise.

"——Teacher!" Xiaoxia ran over and shouted, "It's really fifty-three feet! Thirteen me am fifty-three feet tall!"

“Could it be that everything can really be represented by ‘numbers’?”

"Well, the school I just mentioned thinks so. As for whether the idea that everything is number is correct or not...that's up to you to prove it."

Lou Wuchen smiled and said something that the children did not understand.

——I hope my Hippasos can appear among you.

At noon, Lou Wuchen stopped teaching and rang the bell in his hand.

"...Okay, that's it for the morning class. After class, come with me to the cafeteria for dinner."

Then, Lou Wuchen led the children to a big house next to the square: "After entering, wash your hands at the door first, then each person will take a dinner plate and a pair of chopsticks, and line up in front of the window in order..."

The appearance of the house made the children feel very fresh. There were rows of long tables and chairs in the very open hall. At first glance, it seemed that there was no end in sight. It had an extraordinary momentum. There were several rows of tables and chairs lined up on one side of the hall.

There are counter-like windows, and in each window there is an aunt in white clothes and white skirt, with pots of steaming food in front of her, which makes people appetite at the sight of them.

The initial situation was a bit chaotic, and the children were not sure what to do at first. However, under Lou Wuchen's arrangement, the order he wanted was quickly formed. The children lined up in an orderly manner on the yellow line drawn

In the long area, people carrying iron plates divided into several compartments walked to the window one after another and asked the lady inside the window to scoop the food into their own iron plates.

The child who got the meal first was a little embarrassed. After Lou Wuchen signaled several times, he sat down on the bench with an iron plate and started eating. The children who followed gradually relaxed and naturally found their own places.

The familiar children sat together and chatted while eating. Lou Wuchen didn't plan to eat at all, but looking at the meal prepared as a demonstration on the plate, he smiled bitterly and found a corner in the large canteen.

He put down his plate and sat down.

The long-lost freshness of rice and the rich aroma of vegetables hit Lou Wuchen's face. The familiar style of the iron plate in his hand, which he personally designed and the familiar pattern of ginkgo leaves, made Lou Wuchen feel dazed for a moment, and his vision suddenly blurred.

Got up.

"...Teacher, are you crying?"

Lou Wuchen recovered from his momentary trance, looked at Zhang Zhaoqing who had sat down at some point in front of him, smiled and said, "Teacher is not crying."
