"Master, I've finished memorizing it!"

Fang Yizhi held his little head up and looked at Xu Mu expectantly.

Xu Mu glanced at the two fleeting figures on the window on the second floor, and his lips raised.

The reason why he asked Fang Yizhi to recite the Three Character Classic was to let them hear it.

The influence of this enlightenment book on Wang Tong is by no means less than the "Four Forms" mentioned earlier.

However, in the Three Character Classic, many things, customs, allusions, history, etc. were taught, especially after "I passed on to the Sui Dynasty, and no longer passed on, and lost the tradition", the writing was "Gaozu of Tang Dynasty, an uprising army. He eliminated the chaos in the Sui Dynasty and created the foundation of the country."

Of course, Xu Mu would not make these low-level mistakes and delete all the subsequent "prophets" history.

In addition, Su Laoquan and the Twenty-Seventh Sui story were also eliminated by him.

"Where is my reward..." Fang Yizhi reminded again in a low voice when he found that Xu Mu ignored him.

Xu Mu came back to his senses, touched his little boy's belt, and said with a smile: "Today I will teach you a way to calculate the mountains are high and far away."

Fang Yi blinked his eyes and raised the map to draw it, and he became energetic.

During the month when the lord walked, he drew topographic maps through contour lines and scales, and encountered many difficulties.

For example, the height of a mountain is extremely difficult to measure, so the data of the topographic map he drew was always not so accurate.

After discovering this problem, as soon as the lord came back, he asked him for advice.

Until today, the lord was willing to teach him again.

Xu Mu did not expect that Fang Yizhi, who was only in his early 10 years old, actually showed amazing talent and passion for learning in the topographic map production.

Immediately, I popularized a theory with him, the similarity of triangles...

"What is the similarity of triangles?" Fang Yi was confused.

On the second floor, the two people heard about Professor Xu Mu's things related to the topographic map, and even raised their ears and listened to the window.

After touching the contour lines and scales, they were amazed.

I know that this is crucial to marching and fighting.

You can give the generals enough data to estimate the speed of the march, as well as various ambushes you may encounter along the way, etc.

"This method was actually proposed by Liu Hui of the Three Kingdoms period in "The Calculation of Islands". After summarizing, he found that two triangles with similar angles have a certain proportional relationship."

Xu Mu pondered for a moment and expressed this profound theoretical point for people of this era.

Afterwards, Xu Mu personally drew two similar triangles, divided several of their sides together, and demonstrated them to Fang Yizhi.

“It’s really the same!”

Fang Yi stared wide, and a crisp and tender voice echoed outside the small western-style building.

He had a strong desire for knowledge, and he made many calculations himself and found that as long as it was a similar triangle, the ratio of the two sides' divisions would be exactly the same!

"Lord! I understand! If we want to measure the height of the mountain in the future, we just need to establish an observation point, then measure the distance between the observation point and the foot of the mountain, and build a similar triangle, and then we can calculate the height of the mountain! Similarly, knowing the height of the mountain can also measure how far we are from the mountain!"

After some explanation, Fang Yizhi, who has a scale basis, quickly understood the theory Xu Mu talked about.

He was so excited that he quickly picked up the map of Wanmincheng Mountain that he had drawn before and continued to measure.

Xu Mu nodded with a smile, letting him practice it alone, and he prepared to go to find an old house to popularize the "Three Character Classic" and "Thousand Character Classic".

At this time, the two people on the second floor were confused and looked at each other.

"Mr. Wang, do you... understand?" Lu Chu showed a confused look.

Wang Tong smiled bitterly and shook his head: "No...no..."

Immediately, the two of them looked at Fang Yizhi, the child in his early teens.

He seemed to understand...

With a desire for knowledge, the two went downstairs...

Wang Tong claimed to be a great scholar and was very proficient in mathology, but he did not hear the similar triangle of Luo Shizi for a while.

"Yizhi, what's going on with the similar triangle that the lord just said to you just now?" Wang Tong squatted down and asked in a harmonious voice.

Fang Yi straightened the two adults who didn't work. His father said yesterday that these two people were unwilling to surrender to Wanmincheng.

Therefore, he has no good feelings for the two of them now.

If you don’t work, you will eat and drink here every day.

He gave the two of them a blank look and Fang Yizhi continued to measure himself.

Wang Tong and Lu Chu were stunned. From Fang Yizhi's little eyes, they seemed to have read five words.

Don't even understand this?

Even though the two of them were very well-educated, they were depressed and slightly unhappy by a child.

"Huh? What is this?"

The question in his heart was not answered, but Lu Chu found a volume of scriptures beside Fang Yizhi.

After turning it open and seeing the content, Lu Chu was stunned and stood there on the spot.

Wang Tong stood up and came over.

It was also like he was imposed on the stamina and stood there on the spot.

I just heard Fang Yi recite it directly, but the two of them didn't hear it very clearly.

But at this time, when they saw the original text of the Three Character Classic, they were deeply shocked.

It is not only catchy, but also inspires the people from all aspects, lets them know the inheritance, the classics, and loyalty, righteousness, benevolence and filial piety.

But when they saw "reaching to Sui, Yituyu, no longer spread, lost his tradition", they rushed over and felt Xu Mu's ambitions.

Or ambition!

What does it mean to stop spreading?

Especially Wang Tong, combined with what Xu Mu said to him a few days ago, he was even more thoughtful.

The ambition is self-evident, and Xu Mu wants to end this chaotic world with his own strength!

So there is no Li Mi, no Li Yuan, no Dou Jiande and other people...

Wang Tong took a deep breath, forcibly suppressed the shock in his heart, and then continued to look down.

I have to say that the "Three Character Classic" was so full of sensation that it shocked him greatly.

It made him shake completely.

"Follow such a lord, maybe... I can really revive Confucianism and educate all the people?" Wang Tong thought so in his heart.

There are not many lords who are so ambitious, respect Confucianism, and value education...

"Sir, look, there is another article...thousand-character text behind it?"

Lu Chu interrupted Wang Tong's thoughts in a deep voice and pointed to another thousand-word words behind the Three Character Classic.

"The heaven and earth are mysterious and yellow, and the universe is vast.

The sun and the moon are full, and the sky is full of heaven and earth are surrounded by heaven…”

Wang Tong took it off and started chanting it.

While reciting, trembling.

The shock in my heart is conceivable.

Such a famous universal chapter, the lord actually... took out two volumes at a time!

...

This was naturally left by Xu Mu on purpose.

It's just to attract the two to the bait.

When Xu Mu returned from the lord's mansion building, he found Wang Tong standing alone at the door of the first floor, as if waiting for something.

He hurried forward and greeted, "Old Wang?"

Wang Tong looked solemn, as if he had made some major decisions.

From a distance, he bowed to Xu Mu and held the courtesy of his subjects.

Xu Muxin was happy and quickly stepped forward and helped him up.

"Has Lao Wang figured it out?" Xu Mu was overjoyed. You know, this is his future Minister of Education.

The most talented person in the entire era.

Moreover... he had many disciples, and he was taught by the Luoshui River back then, and countless disciples came to visit him.

In the future, those people will be prime ministers in the early Tang Dynasty.

If you kidnapped Lao Wang, wouldn’t these people be involved in his future?

Wang Tongzheng pointed at the head and said in a deep voice: "What the lord has learned is well-versed in the past and the present, and he is far-sighted and ambitious. Zhong Yan is not talented, and he is willing to work hard for the lord!"
