Datang: Wrong start into the bridal chamber, the bride is Jinyang

The servants outside did not dare to neglect, so they hurriedly went out to find two pieces of iron, and delivered them to Li Yuanxiang.

Seeing this, Fang Jun smiled and said: "This attempt is not accurate enough. Why don't we go outside to test it. Stand higher, let the time last longer, and let your highnesses take a good look, which piece will land first?"

"Afraid you won't succeed? Let's go outside for an interview!" Li Yuanxiang said, and immediately got up and walked outside.

When Li Zhi saw it, he couldn't help frowning, and said to Fang Jun: "Master Fang, this method...doesn't the heavy one hit the ground first?"

Fang Jun laughed, and said, "This...it's hard to say! Go over and have a look later and you'll find out! Come on, let's go and have a look too!"

Li Zhi hesitated for a moment, and could only laugh: "Okay! If the heavy ones didn't hit the ground first, it would be very interesting!"

After he finished speaking, he walked outside.

There are many attics near the South Study Room, and he found a taller attic right away. Li Yuanxiang asked someone to climb up to the third floor with an iron block, and then said to Fang Jun: "Fang Changshi, you should keep your eyes open to see what is going on. Which one hits the ground first? Ah Fu, let go!"

"Yes!"

The servant named Ah Fu released the iron block at the same time, only to hear a slap, and the two iron blocks still fell to the ground at the same time.

At this moment, except for a few people who hid in the south study and did not come out, everyone who saw it couldn't help but exclaimed.

"Why is it still like this?"

"Why is it still like this? What kind of magic is this?"

"His Royal Highness Feng, isn't your iron block right?"

The people discussed and said.

Li Yuanxiang gritted his teeth immediately, still couldn't believe it, and said, "Ah Fu, try again!"

"Yes!"

The man named Ah Fu ran down quickly, picked up the iron block, and then let go of his hand.

Everyone held their breath and watched, only to hear a slap, and the two pieces of iron fell to the ground at the same time again.

Now, with a swipe of the floor, almost everyone turned to look at Fang Jun.

Fang Jun laughed, nodded and said with a smile: "Everyone has seen it! It is not the heavy objects that fall to the ground first! Therefore, today we need to talk about the first principle of heaven and earth, the first way of heaven and earth. That is, the same height, let go at the same time, then almost all objects will fall to the ground at the same time! There is no difference in weight, only difference in size!"

"So, this is what we are going to talk about today, Daoyi!"

Chapter 111 Pandora's Box Is About to Be Opened

Everyone immediately looked at him and looked at each other.

"Regarding this matter! I am somewhat confused, so I have done many tests! But the results of each test tell me. The same object, regardless of other factors, no matter how heavy or how big they are, It landed at the same time!"

Fang Jun continued to look at them and said, "Therefore, we have a lot of questions? Why did they fall to the ground at the same time? Why didn't the heavy one hit the ground first? If this is the case with iron? Is it the same with wood? We are also the same? What does this mean?"

"Fang Changshi, I think what you said is wrong! The same is not the case with iron and feathers! As we all know, iron must be much faster than feathers!" Li Yuanxiang said.

Fang Jun laughed, looked at him and said with a smile: "Does His Royal Highness Feng know why a feather is slower than a block of iron?"

"This one……"

"This young slave knows! Of course it's the wind!" Li Zhi said.

"Yes! It's the wind!" Li Yuanxiang also nodded hastily.

Fang Jun laughed immediately, and said: "So, what we just talked about is Dao Shengyi, and this is Dao Sheng Er, there is wind! Now I will ask His Royal Highness Feng a question, if there is no wind, the same place, the same time , two feathers of different sizes fall, which one is faster?"

"This……"

Li Yuanxiang's eyes widened slightly.

"Naturally, we still land at the same time!" Fang Jun said with a smile: "We can continue to do a lot of tests. But we must pay attention to the need to use the same object. Different objects are naturally different. Because there is wind, there are others……"

"How strong is the wind? How much does it affect the objects? This is Dao Sheng Er. Let's not talk about this today! Come with me! Let's go back first!"

Li Yuanxiang, Li Zhi and the others looked at each other, frowned, their faces were a little dignified, they didn't say much, and followed Fang Jun back to the South study.

Here, there are three people, Li Zhen, King of Yue, Li Shen, King of Ji, and Li Min, King of Shu. They did not participate in Fang Jun's messy affairs.

Fang Jun didn't bother to pay attention to them, he took out the white cloth and wooden board that had been prepared, took out the charcoal, wrote a few words on it, and said: "So, now we have come up with an answer, that is, in the case of the same objects Now, in the absence of wind interference, the falling time of the object is the same! It has nothing to do with the weight of the object! Do you agree?"

"This one……"

Everyone looked at each other and nodded.

But someone said: "Fang Changshi, what's the use of you talking about this? Even if the time of whereabouts is the same?"

Fang Jun glanced at the person and found that it was Ji Wang Li Shen, so he said: "Of course it is useful! Since all objects fall at the same time, can we calculate and prove that there is a force pulling us down? And this force has nothing to do with how big or how heavy we are? Even the falling speed of a huge object is similar to that of our falling object!"

"Can we still deduce it. Everything in the world is the same, whether it is a person or other objects?"

"Fang Changshi, how can this be generalized? You need to know about other items..."

Li Yuanxiang wanted to continue to say something.

But Fang Jun waved his hand to interrupt him and said: "We all know that when we jump off, we will fall down, and if the ruler is loosened, it will fall down. It is the same if there is an apple here. If it falls, it may hit the apple. His Royal Highness, your head! But no one can explain why we must fall down? Instead of flying towards the sky?"

"It doesn't matter whether it's the theory of ghosts or gods, or anything else! Let's put it aside for the time being. Today, we will first prove one thing, that is, in the absence of wind interference, without considering the different situations of objects. Now, the falling speed and time of all objects are the same! Exactly! Right or not?"

Everyone frowned suddenly, their faces full of solemnity.

Li Zhi also stared at Fang Jun and fell into deep thought. He had heard Fang Jun talk about this a long time ago, but he hadn't talked so deeply before.

"I still have questions!" said a prince.

"Say!"

"The iron block and the feather..."

"I've already said, don't consider the wind, don't consider the different objects!" Fang Jun said, feeling that this group of children is really difficult to explain, and continued: "The same object, the same time, we just did the test."

Ji Wang Li Shen sneered again: "Even if it is true, so what? Fang Changshi, what are you going to talk about?"

Fang Jun glanced at him and said: "Today I will give a lecture, nothing else! What I can talk about is to teach you how to look at problems, how to understand everything in the world. How to understand the Dao of the world!"

"Ji Wang Li Shen, what I'm talking about today is that objects fall at the same time. There is a reason for this, and we don't know exactly how! But we can sum up some things."

"So what?" Ji Wang Li Shen continued.

"No way! It's just... if we can sum up these things and understand how the Dao works inside! Then we can fly to the sky!"

Li Shen was taken aback, startled.

Fang Jun continued: "I don't know if His Royal Highness Ji Wang has thought about it? Why can Kongming lanterns fly into the sky? This year's Mid-Autumn Festival, I have seen countless Kongming lanterns flying into the sky, and Jin Wang Jinyang and I have made several. You know, it Why can it fly? And we can't?"

"This one……"

Ji Wang Li Shen frowned.

"So, we came up with another Daoyi! That is, objects can fly into the sky, and we can fly into the sky too! It's just that we don't know or understand it for the time being, so we can't fly!"

Fang Jun said: "I don't know if everyone has thought about it? If we make the Kongming Lantern big enough, can it also take us to the sky?"

Li Zhi, Li Shen, Li Yuanxiang and the others couldn't help being stunned for a moment, their eyes widening.

"How, how is this possible?"

Li Yuanxiang exclaimed.

"Why is it impossible?" Fang Jun stared at him and said, "Since Kongming lanterns can fly by hanging candles, why can't you take us to fly?"

"This this……"

Everyone looked at each other in blank dismay again, many of them had widened their eyes, their breathing became short of breath, their faces were in disbelief, as if they had seen a ghost.

Even Shu Wang Li Yin raised his head!

Seeing this, Fang Jun couldn't help but nodded.

Not too difficult to teach!

He continued: "Of course! There are still many problems to be solved! That is, how big a Kongming lantern is needed to fly with us? Will we die if we fly up and fall down! But my son-in-law believes that, If the Kongming Lantern is big enough, unimaginably big, it will definitely be able to take us to the sky!"

"This, is this really okay..." Li Yuanxiang said with wide-eyed eyes.

"It seems... that's true... Logically speaking..." Ji Wang Li Shen frowned, his face full of solemnity.

"If it's big enough..."

Seeing that everyone has quieted down, Fang Jun couldn't help but understand, and continued to smile: "So, at this time, we have derived Taosheng [-] from Daosheng [-]: that is, we can also fly into the sky. We don't necessarily We will fall! There is a force pulling us down, as long as we get rid of this force, then we can fly to the sky!"

"Ghosts and gods, we don't necessarily have to land!"

"Of course! Now we have more questions: What is the name of this force that is pulling us? How big is it? Are all objects the same size? If it is the same size, can it be proved Is there a reason to follow, rather than invisible?"

"The simultaneous landing of the iron block test just now is based on this!"

"As long as we find out this power, and then use objects like Kongming lanterns to get rid of it! So, does that mean we can fly into the sky?"

"His Royal Highness, do you think this is useful?"

Li Shimin, are you afraid?

After finishing speaking, Fang Jun thought mischievously!

Pandora's box is about to be opened!

Chapter 112 The Difficulty Is How to Knock

There was a lot of discussion in the South study.

Everyone has seen Kongming Lanterns before, but everyone didn't think about it that much, and they didn't dare to think about it. However, Fang Jun's pointing it out at this time really made Li Zhi and others frown.

The iron blocks falling to the ground at the same time may not have that deep feeling, after all, what is the use of falling to the ground, but when it comes to Kongming lanterns, everyone can't help thinking about something.

"Fang Changshi, is this really okay?" Li Zhi asked.

Fang Jun glanced at him and shrugged: "I don't know if it is possible. But what I know is that it may be possible! We need to find a way to confirm whether it is possible! We can find it through different tests The law of the law, find its traces. If you find it, it is the great way!"

"And if it's not possible, then what are the reasons? We need to find these reasons and find out the rules. Then we can sum it up!"

"As long as we find these unacceptable reasons and eliminate them one by one, then it will be fine naturally!"

"That's what Kongming Lantern is all about!"

Li Zhi frowned: "Is there such a saying?"

Fang Jun nodded and said: "Well! Of course, if you want to fly, there are still great difficulties. For example, the wind is very strong above, and you will die if you fall! Kongming lanterns are made of paper, and they are easy to crack. It’s very big. If you want to do it, you need to find out one of them, and then solve it! This is a way to think about the problem after all!”

"Fang Changshi, can you make it?" Li Zhi continued to ask.

"Me?" Fang Jun was stunned, and said with a smile, "I can't do it!"

The others were taken aback, Li Yuanxiang curled his lips and said, "Since you can't do it, how dare you say it?"

Fang Jun smiled and said: "There are many reasons why I can't do it. One is that it is not good to use paper, which is too easy to tear. And if it breaks and falls, it will be death! It is very dangerous! It is not good to use cloth, as far as I know At present, there is no kind of cloth available. If you are interested, you can try to make a bigger Kongming lantern, and tie a chicken or a duck!"

"Of course! These are very dangerous. You must be cautious and cautious when doing this! Well, these are digressions, let's leave it alone for today!"

In the Tang Dynasty, it was simply unrealistic to make hot air balloons. This required the research of densely stitched linen, but there is no such linen now.

Almost all sackcloth is now handmade, not only is it easy to tear, but also leaks air, even silk is useless.

If you want to make a hot air balloon, you must first develop a linen cloth that is resistant to high temperatures and has dense stitches. This did not appear until the Song Dynasty, and the industrial level of the Tang Dynasty was still too low.

Of course, Fang Jun didn't say no, he just let them think for themselves. Anyway, the problem has already been thrown out, so it won't be wrong to think about it.

These princes and princes have a lot of money, and they are idle when they are idle.

Naturally, there is not much time for a class, and Fang Jun finishes it quickly.

After asking the question, he didn't bother to pay attention to these princes and princes, and walked outside with the book, leaving a group of people looking at each other in blank dismay.

"Maybe we can really try it!"

"Just try it with a chicken or a duck!"

"But what Fang Yiai said is also reasonable, if you go up and fall down, you will die!"

"Proceed with caution..."

Several people became excited, as if they wanted to see if this was the case?

Seeing this, Fang Jun found Li Zhi and said, "This matter is too dangerous. Don't allow people to go up and try it easily. You can use other objects. If someone goes up, you have to stop them!"

Li Zhi nodded and said, "I'll know naturally. But Fang Changshi, do you still have the Dao Shengyi you mentioned?"

Fang Junle thought for a while, and said with a smile: "I don't really understand this either. But what I know is that you need to look more, think more, and observe more! The doorway, the law, can respond to all changes with the same!"
