I was a gentleman in ancient times

Everyone didn't know why, and they didn't know what kind of mystery Wei Su was playing.On the contrary, those who had listened to the lecture before were shocked, knowing that this must be a surprise prepared by Wei Su.

Not long after, I saw a few servants bring up a few things, a bulging one made of cowhide sewn together like a ball, and a few small stone bumps.

Wei Su took the ball in his hand and weighed it. It wasn't heavy, and it wasn't as round as he imagined.

Wei Su didn't talk nonsense, and started to demonstrate directly, "If this is where we stand..."

Before the words were finished, everyone laughed, "How can such a ball stand up to people, fooling people, right? Isn't talking too much? Hahaha!"

Wei Su raised his head, not annoyed, but narrowed his eyes slightly, "What if we magnify this ball tens of millions of times? People are like ants, can they still stand? Or imagine inversely, putting an ant Can it stand on it? Do you know what is under its feet?"

"This..." It makes sense when you think about it. The faces of those who laughed just now were a little hot, and some people still refused to admit defeat, and said stubbornly: "Hmph! How can people be compared with ants?"

"In my opinion, looking at the entire universe, there is no difference between humans and ants." Wei Su said lightly.

Wei Su didn't intend to argue too much with such a stubborn person.He continued his explanation, "Why do things fall to the ground instead of flying into the sky. You can see, this little thing in my hand, as long as I let go, it will fall to the ball no matter which direction it is in."

After finishing speaking, the small iron lump in his hand was absorbed by the ball the moment he let go.

"Huh?" Everyone clicked their tongues. How did this happen?

Mr. Gongsun was thoughtful, and after careful observation, he hesitated and said: "I heard that there is a kind of kindness stone, which can be attracted by iron. Could it be that there is that kind of kindness stone in this ball?"

Wei Su nodded, "Indeed, there is a kindness stone in the ball, so the iron stone will be attracted by the ball. In the same way, whether there is such a material attraction in the invisible places under our feet can attract everything on the ground. Stones, fruits, leaves... everything in the world will only fall to the ground, is it caused by its suction?"

"But you can't see or touch the things underground, so how can you tell that they are attracted by the things below?" Chu Yan stroked his beard, "Do you want someone to dig it up and have a look?"

"True digging is impossible, but conclusions can be drawn through the law." Wei Su raised the ball in his hand to the sun, pointing to the sunny side, "Look, facing the sun is daylight, but it can't be illuminated below." The place where the sun is is the night. When it is turned around, day and night alternate, and it goes round and round, endlessly."

"Absurd! Absurd! How can this make sense?" Mr. Gongsun shook his head again and again, "This statement is really unbelievable. I really don't agree with this statement. If we don't agree with each other, we will leave!" go.

Seeing this among the students, most of those who could not understand stood up and left their seats one after another. These people were all shocked by Wei Su's words.Such a view is completely different from what they have always believed since they were young. How can they believe it?It's like something that has been believed to be true for a long time, and someone suddenly said that it is not like this, but an unexpected existence. Doesn't this shatter people's three views?

This kind of nonsense, if they listen to it any longer, it will be an insult to them.

Some people left in a hurry, and some people saw this situation, their hearts were shaken, and they didn't know whether to leave or stay for a while, so they simply looked at the situation before talking.

Seeing that more than half of the people had left, Tao Jin became anxious, what... what's going on?This lecture is not over yet, how can I give a lecture when everyone is gone?

Xie Zhuo glanced at the gentlemen in front of him. Except for Mr. Gongsun, the others were so calm about this situation that they didn't even move their fingers.It seems to be to see how Wei Su handles such an unexpected situation.

"What's the rush? Let's go if you want, they're much cleaner after leaving, no matter what, there are more people than the last lecture, right?" Xie Zhuo said very indifferently.

Tao Jin thinks about it too, he can count on ten fingers in his first lecture.Anyway, even if everyone left, he wouldn't leave. Thinking about it this way, he felt more at ease.

Xun Qi looked around, feeling a little anxious, how could these people leave without saying anything?Can't you consider other people's feelings?

Instead, Qin Zhan tugged at his sleeve and shook his head at him.

"Hmph! A group of villains, villains who have fallen into trouble!" Xun Qi complained angrily, hoping that Mr. Wei would not be influenced by these people, after all, there are other gentlemen still there.

All of a sudden, there were only a small group of people left on the field. Wei Su's expression didn't change at all, and he continued his lecture calmly without being affected at all.

Wei Su's calm attitude fell into the eyes of all the gentlemen, and they couldn't help but secretly nodded in appreciation. It is very rare to be able to stay calm in the face of danger at such a young age.Even old guys like them would not be able to be as calm as Wei Su.

"Of course, this is just my opinion, my humble opinion. Everyone may agree or not. The so-called harmony without difference, seeking common ground while reserving differences, can develop and progress. This is the reason why Yingyang Academy can stand forever and is sought after by scholars all over the world. The reason. I am very glad to be here and see with my own eyes the scene of a hundred schools of thought contending and a hundred flowers blooming, and everyone is working hard for their beliefs.”

This is also one of the reasons why Wei Su dared to put forward this controversial theory, the good learning atmosphere of Yingyang Academy.Even if it is absurd, as long as there is a certain truth, you can put it forward according to your own ideas, and it is very possible to form a school of theory after hard work.

Now it is not like thousands of years later, Confucianism is the only one, and hundreds of schools are dismissed.Anyone who has such absurd thoughts will be regarded as a monster, and will be suppressed if they show their heads.

Huangfu Yong laughed and clapped his hands and sighed, "A hundred schools of thought contend, and a hundred flowers bloom. Isn't this not the original intention of a holy master? You can do this, very good, very good!"

With Huangfu Yong's affirmation, those who were worried before were finally relieved.There were also people who were thoughtful, Wei Su's words seemed to open a new door for them.Perhaps, going in this direction is also a very good path.

Although I don't know where the road leads, and I don't know how rough the road ahead is, but a brand new road has given many people curiosity and want to find out.

"The things I put forward today may seem unbelievable now, but if there is no idea, then there is no direction. I am just a humble forerunner, and I hope that some people will follow this direction. A hundred years, a thousand years, Even thousands of years later, later people will have great achievements."

Wei Su told his ambition, he just wants to ignite a spark, as long as this spark can be preserved, who knows if this spark will start a prairie fire in the future?

The students who are sitting now can continue to listen, which means that there is such a glimmer of hope, doesn't it?

Lectures will continue, Wei Su stopped talking about those profound and mysterious things, in order to improve the enthusiasm of the students, he simply started a small scientific experiment.

"Someone suggested turning stone into gold before, and here I want to tell you that this is impossible. But everyone knows the method of freezing water, but do you know the method of igniting fire with ice?" Wei Su smiled and threw out an absolutely impossible possible problem.It almost blows up the people below.

"What? Fire with ice? How is that possible?"

"It's absolutely impossible, Mr. Wei thinks we are stupid?"

"The words can't be so absolute. Mr. Qian Wei pointed out that water is ice, didn't anyone think of it?"

"That's right! Didn't Mr. Wei say that? Real knowledge comes from practice, don't you know if you try it? You can see such a scene with your own eyes today, and you can scare a lot of people by telling others after you go out, right?"

The people below talked a lot, some didn't believe it, and some looked forward to it, just waiting to see how Wei Su ignited the fire with ice.

Over there, Wei Su had already prepared a convex lens made of a large piece of ice, and he didn't see how he moved. After a while, a pile of dead grass next to him was smoked and flames burst out.

Everyone stretched their necks and kept their eyes fixed. When they saw the flames, they couldn't sit still.

"Ah! Sure enough, it caught fire."

"My God! How is this done?"

"It's really unimaginable. Could it be that there was help from ghosts and gods?" Obviously there was no one around the haystack, let alone something that ignited the fire. Where did the fire start?Except for ghosts and gods, they can't imagine other reasons.

Even the gentlemen showed expressions of astonishment, Wen Liang and the others couldn't wait to go over and check it out. He turned around the fire several times, yes, it was really burning, and besides the dead grass, he didn't find any ignition source at all. things.

He shook his head in disbelief, "How did this happen?"

The last time Wei Su's water was iced, there is still a trace, that is, Wei Su threw saltpeter into the water to freeze it, but now, there is no clue, no one is near the haystack, even Wei Su is standing. Far away, not even a step closer.

He paced back and forth, unable to figure it out.

"Do you have any ideas?" Wen Liang asked the other people directly, wondering if they had discovered anything.

Everyone else shook their heads, their faces full of disbelief.Even if they are well-informed, they have never seen such a strange thing.Today, Wei Su let them see it.

Wei Su smiled lightly, the ice cube in his hand had already melted into a puddle of water.After taking the handkerchief from the servant and wiping his hands, he sat down on a chair beside him and took a sip of tea.

Everyone discussed to no avail, and finally Qiqi looked at Wei Su, and Chu Yan asked first: "How did you do it? It seems that it is against common sense and impossible. But we I’ve seen it with my own eyes, and I don’t believe it.”

"You really didn't expect the reason?" Wei Su was lazy and speechless, "But I clearly explained it very clearly from the beginning."

This... did he say anything?no?

"Hahaha!" Wang Ziqi laughed and slapped his thigh, "I know, I know!"

Everyone looked at him, Wei Su nodded to him, "Prince Qi might as well talk and listen."

Xun Qi stood up triumphantly, "Mr. said at the beginning that the fire was lit with ice. I think the source of the fire is related to the piece of ice in Mr.'s hand. I don't know if it is true or not?"

This is what Wei Su said at the beginning, and everyone knows it, but how the ice ignites the fire is still a mystery.They only saw Wei Su tossing and turning the ice cubes, so what did it have to do with the fire?

Wei Su nodded, knowing that no one would be able to guess the reason, so he stopped playing tricks, "I did use that piece of ice as a medium to ignite the fire."

"How can it be done?" Wen Liang asked anxiously.

"Because there is not only ice, but also the sun!" Wei Su pointed to the sky.

Everyone looked at each other in blank dismay, getting more and more outrageous, what does this have to do with the sun?

Wei Su smiled, "Everyone has seen it too. The ice in my hand was facing the sunlight just now, and the sunlight was focused on a certain point through the ice. I call this point the focal point, and the temperature of this focal point is enough to ignite dead grass. gone."

"How is it possible? It's not like I haven't seen it before, and I've never seen something that can be ignited by shining the sun." Wang Ziji shook his head and said, how can this explanation convince the public?

"Ordinary ice cubes can't do it, but the ice in my hand has a different shape called a 'convex lens'. Only such a convex lens can focus the light to one point." Wei Su explained, reaching out to the servant He made a move, "I made a few more here, and everyone who is interested can take a look."

Everyone couldn't wait, and sure enough, there were several ice cubes of different shapes in the ice bucket.Unexpectedly, it is such a thing that can be ignited by borrowing sunlight.What is in Mr. Wei's head?Such a weird way can also be thought of.

Chu Yan also took a piece of ice, and did something to the sun just like Wei Su did just now.Sure enough, I saw a light spot on the ground, and mapped the light spot to a combustible object, and soon there were fireworks.

Now, no one dared to question Wei Su's words anymore. The seemingly complicated and impossible things turned out to be so simple and so interesting after Wei Su's eloquence.They have gained a lot of knowledge, but it is a pity that the group of people who left earlier missed such a wonderful experiment.

Many people became interested and made up their minds that they would definitely come to listen to Mr. Wei's lecture next time.
