Everyone was resting by the lake, but they couldn't calm down. Soon the topic turned to those gentlemen again.

The teaching method of Zizhu Academy is very terrifying, and the collection of Zizhu Academy Library is also very terrifying, which everyone can understand.

However, the existence of those gentlemen really shocked them, and they were the ones that everyone cared most after they came to their senses.

Those non-human beings.

Tonglan felt very comfortable listening to everyone's words.

It's so fun to tease these people, I didn't have this opportunity in the past.

Ning Changqing walked to Tonglan and sat down, and smiled and said, "We are really eye-opening today!"

After hearing this, Tonglan was a little hesitant about how to answer.

Ning Changqing didn't wait for her to answer, but just asked with a smile: "Is the old man in the library the one on the list?"

"Do you know?" Tonglan thought for a while and said, "I have never lost anything in the school, thanks to him!"

"With him here, who can steal things here?" Ning Changqing confirmed the guess in his heart and smiled bitterly.

It was indeed him.

Such a character actually works as a janitor in Zizhu Academy...

He let out a long sigh and spoke again: "What are you all learning?"

"Chinese, mathematics, chemistry, physics!" Tonglan calculated with only four types of fingers.

There are so many aspects involved in libraries, such as sociology, psychology, architecture, poetry, medicine, education, materials, agriculture, philosophy, law, manufacturing, economy... there are too many.

Thinking of this, Tonglan felt that her academic courses were no longer heavy.

If you want to learn everything... even those perverts with swords on their backs can't do it!

Ning Changqing became interested and asked, "What are these? Can you tell me in detail? I am very interested."

Tonglan raised her eyebrows, a little impatient.

However, seeing that these people brought so much fun to themselves, they pressed their eyebrows down and said in a calm voice: "Chinese is to learn literacy, mathematics is to numerology, you also have to learn the "Journal of the Conclusion"? It is similar to the "Journal of the Conclusion".

As for physics, the various phenomena in the nature of the world, the structure of matter, the interaction of matter, and the laws of matter movement."

Ning Changqing interrupted Tonglan and asked, "The material you mentioned..."

"Everything between heaven and earth cannot be touched, as long as it actually exists, it is all in it.

Whether it is the soil, stones, trees, flowers, plants, birds and beasts, the breathing air, the clouds and lightning in the sky, the ice and snow on the peaks, they are all in it."

Ning Changqing listened to the other person's words and looked shocked.

The students around who were attracted by this conversation couldn't help but say, "Isn't this the Great Way of Heaven and Earth?"

"I did say that back then." Tonglan thought about it carefully, "It's right to say that."

In the eyes of others, it is the Great Way of Heaven and Earth, and in the eyes of these students of the Zizhu Academy, it is divided into different things.

Silent.

Learn the great way between heaven and earth?

"It's not as powerful as you think." Tonglan was so thin-skinned that she explained: "For example, why did the fruit on the tree fall? It doesn't fall into the sky? Instead, it falls vertically?"

"Because the earth is below?" someone asked subconsciously.

"Then why did it fall below?" Tonglan asked back.

Everyone: "..."

Few people have thought about this kind of natural problem.

"Why?"

"This is what we learn." Tonglan said lightly, without any explanation to everyone.

This question seemed very simple to her, but the people in the academy began to scratch their ears and faces. Why? No one asked before but he didn't think so. At this time, someone raised it, but said halfway, as if he was tickling his heart with a feather.

"My friend, I am also very curious. I hope you will give me some advice!" Ning Changqing couldn't help but say.

Tonglan then explained: "The earth has gravity! There is gravity between any object in this world, which is one of the several fundamental forces in the world."

When everyone heard the words "one of the fundamental forces in the world", they suddenly felt unaware of the severity.

Even the people chatting were not chatting, and they all gathered behind Tonglan to listen to her talk.

"Since any object in the world has gravity, why is it not sucked into the tree, but fell to the ground?" Xue Yuanpei asked with a cold face. Although he didn't understand it very much, he immediately found the flaw in Tonglan's words.

"The size of gravity is related to the mass. The earth has the largest mass, so it will fall to the earth." Tonglan thought about it and did not say that the world was a sphere. After all, this is just what the book said, but it only said that the earth has the largest mass, so the gravity generated is also the largest.

Seeing that everyone still didn't understand, Tonglan asked back: "Why is this world circling around the sun?"

Everyone in the academy immediately became confused: "Isn't it that the sun rises in the east and sets in the west?"

Tonglan was suddenly stunned. She suddenly realized that there were many things that could not be explained to these people.

If you want to explain, those three days and three nights are not enough.

Finally, I gave up with some headaches: "If you have learned physics, you will know. It's too troublesome for me to explain this to you."

I don’t know who suddenly spoke, “You might be fooling us, right? Otherwise, why can’t you explain it?”

The scene was silent in the moment.

Tonglan's face suddenly became cold. She flashed into the air, looking for the place where she was just talking, and wanted to step on it.

Girl, I kindly explain it to you, but you actually question me?

"Miss Tong calms down, it's just a heartless word." Cao Gui barely kept up with Tonglan's speed, blocked Tonglan and smiled bitterly in front of him.

"Is that... I can't explain it myself..." The scholar who had just spoken said in a low voice again, very dissatisfied in his tone.

Tonglan's face suddenly turned ashen.

"You are too ignorant, so it's too difficult to explain to you!" Tonglan said in a contemptuous tone with anger in her heart.

Many students from Xiaojiang Academy also showed anger.

Xiaojiang Academy is one of the five major academies in Izumo, and they are the best among the academies. Wherever they go, they will not be treated with courtesy?

You demoted everyone to ignorance with just one word, but you couldn't tell me why, how can you convince everyone? How can you not be angry?

"You should tell me, is it because we are ignorant or you are just false!"

"I don't have much knowledge, but I have a bad temper."

Hearing everyone's words, Tonglan felt anger almost erupting.

Since childhood, who has questioned himself so much?

Besides, I would tell them to them with kindness, otherwise I wouldn't bother to pay attention to them.

Unexpectedly, they were questioned as nonsense.

Tonglan's delicate little face was ashen, and she was almost furious and her hair was floating.

"Shut up!" Ning Changqing shouted in a deep voice.

He clasped his fists at Tonglan and said, "My friend, I am only half a foot away from entering the coffin. I can see everything. However, these students are all young people and are full of energy. If you offend me, please don't blame me."

Then he changed his voice: "But if my friend doesn't explain, I'm afraid these disciples are not convinced and think that my friend's false words will not only affect my friend, but also the reputation of Prince Zhao."

Tonglan's chest was undulating a few times, and she stared at everyone fiercely.

I was extremely angry and had to suppress my anger.

At the same time, I also know that if I don’t explain it to everyone, I’m afraid there will be gossip about what happened to Zizhu Academy.

But it is not easy to explain.

Not to mention anything else, the world is just round, and I have to argue with them for a long time.

After a few twists in his mind, he said in a worrying tone: "Have you ever seen a boat going out to sea and return to sail? If you haven't even seen this, then it would be useless to explain it to you much."

"I've seen it." I immediately said.

Izumo and the sea are around the sea, and half of the twenty people have seen them.

"What will the last thing you can see after the ship goes out to sea? What will the first thing you see when the ship returns?"

"Mast!" Many students thought about it and said immediately.

"That's right!" Tonglan raised her head and looked at everyone with a look of looking down.

"Why are the red moon and yellow moon sometimes round and sometimes curved? Have you ever noticed it?"

"Is this related to what you just said?" Although everyone didn't know the reason, they immediately raised objections.

"Of course there is." Tonglan said proudly.

"Don't you always know about the moon in the dark, right?" The moon in the dark is the scene when some of the two moons overlap, usually once in about ten years.

When the moon is dusk, the two moons overlap, and the moon is also missing.

And due to the time period, this process is very clear.

Compared with the moon I usually see, it is actually very obvious.

Ning Changqing suddenly remembered an interesting thing he had heard when he heard Tonglan mentioning the moon. He looked up and stared at Tonglan and asked, "What do you mean is this world round?"
