Infrastructure masters in the red building

"Yes!" The staff member did not forget to ask the Lord before leaving, "That rumor in the palace..."

"The appearance is indeed similar," the third prince thought for a while, "but in terms of character, even if the rumors are true, he will only be able to perform his unique skills for ten days after returning to the palace."

"There are too many young people like this in the world. They are good at being strong but not soft, and they use straightness instead of bending. Such a mind will not last long."

"It would be a miracle if I still flatter and get along with such a person who doesn't suit my temperament." The third prince couldn't help laughing when he thought of this, "If the old man knows, I'm afraid he will think again I'm forming a faction. One thing more is worse than one thing less, anyway, the affairs of Taoyuan Village have already been settled, let the second and fourth brothers help him to deal with this matter!"

The third prince laughed when he said this, and immediately looked like a breezy moon.His staff also laughed along with him very jokingly.

But Jia Fang was regretting that he had a bad cramp and wanted to participate in such a boring "talk" program.

At this time, the sun had already set to the west, and the talk meeting at Ruyiju had just started.In front of every "guest" present was a pot of tea and a plate of finer things.There is no harm without comparison. Jia Fang tasted this tea, and finally knew what grade of famous tea was the "Scaring Fragrance" that he tasted in "Zizaitang" just now.

But during the banquet, everyone's attention was not on the tea and fine points - this was a "clear talk meeting" imitating the celebrities of the Wei and Jin Dynasties, and it was divided into subjects and guests.A scribe who claims to be the "master" sits in the center of the Ruyiju hall and puts forward his own opinion on a certain issue, that is, makes an argument; the people sitting around are all "guests" who question the master's argument.The two sides answer each other, you come and I go.

If a matter is debated to the point where everyone is at the end of their minds, the issue is considered exhausted.The attendants of Ruyiju will hand out a round of counting chips, and select one of the guests who have drawn a special kind of counting chips as the "host", and start all over again.

The form itself is not a problem, but the questions that everyone argues with each other are really boring, and the discussions are all about metaphysical issues, such as "Is everything in the world born from 'existence' or 'nothing'? If it was born from 'existence' , what was before the 'being'; if it was born in 'nothing', where did the 'nothing' come from", or "the wind blows the flag, is it the wind or the flag?"①

and so on.For a moment, it made Jia Fang miss the half-cup of tea discussion with the third prince just now—those are issues related to state affairs, and Jia Fang believes that the truth will always become clearer and clearer.

But how did he know that this "clear talk" is to talk about topics that have nothing to do with state affairs.Discussing how to govern the country, how to strengthen the military and enrich the people, who has made outstanding achievements, is called "common talk", and it is not within the scope of this debate.

The more Jia Fang listened, the more bored he became, and he almost wanted to get up and leave.Unexpectedly, at this moment, the third prince came out of the inner hall of Ruyi Ju, and sat down beside Jia Fang.

Jia Fang couldn't leave for a while, but the scribes who debated in the field became more energetic.

The third prince sat down, held up a cup of freshly brewed tea at hand, put it down after smelling it for a while, and said to Jia Fang with a smile: "How many of us are brothers, the second brother is best at this, and the fourth brother doesn't like this place the most, eldest brother If you come here, you will probably knock over the tea table with one punch—”

Only then did Jia Fang realize that this was the prince of Jian Guo, the fourth prince who had a stuttering problem since he was a child, and the eldest prince who had been leading troops to fight.

Those who didn't know thought that the third prince was just messing around.

Jia Fang sighed softly: Who would have thought that bringing the fourth prince here...isn't it really a bully?

"...Fifth Brother doesn't talk much, but every time he speaks something astonishing, he can kill the other party with just one utterance." The third prince continued.

It was only then that Jia Fang remembered that there was still a "five princes" in this world. Although he was the fifth, he was actually the cousin of these princes.

"I don't know how Zifang will behave when he comes here today." The third prince said, the smile on his face seemed to have faded a lot.

"Everyone, we're going to discuss another topic today, which is—'Qi'."

gas? ——Jia Anxin thought, I'm going to be pissed off by this kind of unnutritious "wonderful flower theory", it's true.

"Everyone, a while ago, one of the audience once made a high-level comment, saying that we usually look at the colorless and invisible 'Qi', but it is actually very heavy——"

Jia Fang's eyes lit up, he raised his head, and saw a scribe standing on the main seat at the moment looking at Jia Fang with a sneer on his face.It turned out that this was the time for the handover of the "host and guest".

The first thing Jia Fang thought of was the fourth prince. From this point of view, it was the fourth prince who publicized the conversation he had had in the refugee camp on the East Road.Could it be that he recommended himself to Ruyijuli?

But he immediately remembered what the third prince said just now, that the fourth prince didn't like this place the most.That person doesn't like to talk too much, so how could he have the time to spread the word?

Then, it should be the one next to you.Jia Fang turned his head and saw the third prince smiling warmly, reaching out to pat him on the shoulder, his eyes full of encouragement.

Jia Fang was silent for a moment, stood up, strode to the middle of the hall, made a four-way bow, and reported his family name: "My surname is Jia, my name is Fang, and the character is Fang. It is true that 'Qi' is colorless and invisible. , but with quality, there is also pressure."

He specifically said "mass" instead of "weight", but not many people should understand.But everyone else understood the words of weight and pressure, and Ruyi Curie burst into laughter.

"This is really a joke."

"Qi... If it's heavy, why don't I feel it?" Someone waved his hand and fanned it in the air: Mingming fanned it very easily and freely.

"Yeah, it's so heavy. I'm so heavy every day that I can't straighten my waist!"

"Help me, I'm about to be crushed to death!"

"Ha ha ha ha--"

"The one surnamed Jia... I seem to know which family he is from. No one in his family has ever stood proudly on the throne of Ruyiju—"

"Don't mention it, the old Jia's family still has something to say about their knives in battle. If they want to sit down and explain the truth... let's wait for a few more generations to talk about it."

The words actually hurt Jia Fang and Rongning's two houses, but it's not surprising that Rongning's two princes have either led the army or been in charge of the defense of the capital since Jia Yan and Jia Yuan's generation.There are also many martial arts among the children, and it was not until Jia Jing and Jia Zheng came here that the atmosphere of joining the army gradually changed.

It would be too "fake" to ask Jia's family to learn to talk about Laozhuang.

"This is a child, you don't know the rules of talking, right?" Someone finally reminded Jia Fang that he might be a beginner.

"What's wrong with the rules? Don't you mean 'don't talk about state affairs' when you talk about it?" Jia Fang laughed loudly, overshadowing the humble comments. "I didn't talk about the national economy, nor did I talk about people's livelihood. I talked about 'qi'."

After Jia Fang finished speaking, he folded his arms and raised his eyes to the sky—the ceiling pattern of Ruyiju is very beautiful. He hadn't noticed it before, so he just admired it carefully at this time, and waited for the people around him to say enough.

His disdain for the people around him really annoyed many scribes in Ruyi Juli.Then someone yelled: "Make an argument, make an argument first, you say 'qi' is heavy, come up with your arguments first, why?"

In this short period of time, Jia Fang had already figured out how to make an argument, so that these idle literati who only knew how to discuss the Tao of Laozi and Zhuangzi could see what the real "theory of all things" is.

He folded his arms, and waited until everyone else had said enough, and then said loudly: "I have a way to prove it!"

"Then prove it!"

Jia Fang then ordered someone to bring in a candle, "Don't want the high-quality smokeless wax, but smoke it." He told the attendant.

After a while, a white candle with candle tears still hanging on it was really delivered, and it seemed that the people from Ruyiju even specially tested it for him.

Jia Fang ordered people to light the white candle.At this time, it was getting late, and all the lights in Ruyiju were lit up, and every room was bright.After the white candle was lit, a puff of black smoke rose slowly.

"Have you seen it? This is the proof." Jia Fang said.

The scribes around were all blinded, and even the third prince sitting below couldn't help but look confused: "What kind of proof is this?"

"It's very simple. Do you see that the smoke is going up?" Jia Fang said, "This is because the air near the candle flame has been heated, so it goes up."

"What does this prove?" Someone immediately retorted from below.

"The hot air goes up because it is 'lighter' than the surrounding air!" Jia Fang laughed.

"Even if it's lighter than other places, what do you prove—"

As soon as he said this, the speaker suddenly got stuck.

Being "lighter" than other places proves that the air is "heavy", otherwise there is no difference in weight.The person who spoke just now regretted his slip of the tongue, and couldn't help but let out a soft "pooh".

Applause gradually erupted in Ruyijuli, and someone praised: "Young Master Jia, at such a young age, you have quite grasped the essence of this debate."

Jia Fang shook his head quickly and said, "I have another way to prove it to you. Qi has weight and pressure. Using it can help us accomplish many things—"

Unexpectedly, the person who kept retorting just now came back to his senses and shouted loudly: "No, it is 'smoke' not 'gas' that goes up! Smoke is not gas."

The wind direction of Ruyi Juli suddenly turned, there was applause, laughter, and whistles, congratulating each other together.The focus of this group of nonsense is that Jia Fang has just extended the word "light" to "weight" to prove his point of view, but now the "smoke" produced by burning candles and Jia Fang need to be certified. The difference between the "Qi" of the other party indirectly proves that the other party's point of view is not valid.

A white horse is not a horse, and smoke is not gas.

Purely from the point of view of verbal and word games, both sides argued very well.

But Jia Fang was very dissatisfied: I really didn't come to participate in the wonderful show!

What he really wants is to use empirical evidence to prove some easily misunderstood phenomena—if one day everyone stops talking and does experiments by hand, will this society still be what it is now?

Jia Fang immediately smiled and said, "Go and get a piece of high-quality smokeless wax!"

The attendant of Ruyiju looked interesting, and responded, and went back and forth, and actually came back with a precious white candle.

"If you don't smoke wax, you won't be able to see the smoke rising." Someone from behind reminded Jia Fang loudly.

Jia Fang immediately smiled and said: "Don't worry, I will let your seeing be believing! By the way, who of you can call my worthless boy in."

It was not Zhao Cheng who went out with Jia Fang today, but Li Qingsong.He should be in the gatehouse of Ruyiju, mixing with the servants and book boys of other scribes.

Jia Fang called Li Qingsong to come in, whispered a few words into his ear, and he still didn't forget to hand Li Qingsong his purse together with the copper plates and broken silver inside.

"Everyone, be safe and don't be impatient. Let's wait for a while, and I will let everyone's seeing be believing." After Jia Fang finished speaking, he secretly called the attendants of Ruyiju and asked them in a low voice about the tea he drank in Zizaitang just now. , is there any more.

The attendants of Ruyiju didn't dare to be the masters, so they turned around and asked the attendants of the third prince, and the words naturally reached the ears of the third prince. It is to know the good and the bad, and know whether the tea is good or bad.

So the third prince shook the folding fan, and the attendants really went to pour tea for Jia.However, the third prince silently admired him in his heart. This kid is quick-witted, but it's a pity that his character... and he had already taken a step ahead, leading an army in the matter of Taoyuan Village——

In fact, thinking about it now, maybe I could have gotten along better with him.

When Jia Fang drank tea, ate snacks, and refreshed himself, Li Qingsong came back, returned the purse to Jia Fang, and said, "It only cost ten big coins."

The rest of the people pricked up their ears, and when they heard it, they all thought, what can ten big money buy to prove Jia Fang's point.Jia Fang took over a bamboo frame and a wad of tissue paper from Li Qingsong.

——What is this?

Jia Fang inserted the precious white candle directly in the middle of the bottom of the bamboo stand, where the two bamboo sticks intersect.Seeing that it was not stable, he asked for some cotton thread, and tied the bottom of the candle to the bamboo frame tightly.

Then he propped up the bamboo raft frame, stretched out the pre-pasted tissue paper, and stretched it on the bamboo raft frame.

At this time, others have already seen what it is in his hand, and someone said: "Kongming Lantern!"

"Yes, it is the Kongming Lantern!"

Anyone who has seen this kind of lamp that slowly rises into the night sky has already pictured in his mind what it will look like when it rises into the sky-as if, indeed, it can explain something.

"The smokeless wax I used, you won't regard the gas inside after burning as 'smoke' anymore?" Jia Fang laughed.

As he said that, he took the lead to go outside, came to the courtyard of Ruyiju, borrowed a fire, and lit the white candle on the lamp.

The outdoor weather conditions are very good, the night sky is clear and clear, and there is no wind.

Jia Fang held the Kongming lantern and felt the hot air overflowing from the lantern.He said loudly while waiting, "This is the proof."

While talking, the Kongming Lantern in Jia Fang's hand was about to move, Jia Fang slowly stretched his arms and opened his hand lightly, and the Kongming Lantern rose slowly in the air.

"This experiment can prove two things at the same time. First, the whole Kongming lantern, together with the air inside the lamp belt outside, has weight; second, the surrounding air produces buoyancy on the Kongming lantern, which makes the Kongming lantern Lifting into the air. The buoyancy generated by the lift is just a kind of pressure produced by the 'air' on the objects inside. This pressure exceeds the gravity of the lamp, and the lamp lifts into the air."

Jia Fang didn't care that the people around him half understood what he said, and he didn't care that Li Qingsong was staring at him with reverence.

"Everyone, if you can make a move instead of talking here, you can confirm many unanswered questions. Why not do it?"

What he said was arrogant, which caused a lot of whispers among the literati.These people don't like others to say that they are "empty talk", and they want others to say that they are "elegants". Jia Fang's words are heartbreaking, but it is hard to refute.

"Okay, everyone, I have answered your questions, and I have done the experiment, and now I am going to chase the Kongming lantern."

Someone asked Jia Fang why he wanted to chase him.

"Safety first, be careful with candles!" Jia Fang explained, "Theoretically, when the candles in that lamp burn out, the lamp will slowly come down. But occasionally, candles will ignite the lampshade. Accidents are easy to fall on houses. So I have to follow-"

Safety and fire prevention are certainly a reason, but the real reason is that Jia Fang wants to take this opportunity to leave this "clear talk", he really doesn't want to waste time here anymore.

Tu Xingsun can escape from earth, ordinary people can escape from urine, and Jia Fang can "escape from light".

So Jia Fang took Li Qingsong, one master and one servant, and hurriedly bid farewell to the master.

"Everyone, there is a saying in "Rituals", 'Extending knowledge lies in investigating things, and knowing things after learning'. Lu Fangweng also said, 'What you can learn on paper will eventually become shallow, and you must do it yourself if you know it'. More hands-on, less empty talk, everyone We will definitely find that the world is not exactly what we imagined it to be.”

After Jia Fang said this sentence, he took Qingsong out of Ruyiju without looking back, closely followed the Kongming lanterns that were slowly marching in the sky, and followed all the way out, leaving behind a large group of stunned scribes.

These scribes looked at each other, and finally someone asked: "What this young man said, could it be... Investigating things to know?"

"This is what the rebellious imperial prisoner Xiang Fengyi mentioned..."

"That's enough, that's enough, this young man didn't mention Xiang's sinner, he was just talking about "Li"?"

"But that means, that means... more hands-on, less empty talk, isn't that, isn't that... what that person said?"

A group of scribes guessed and guessed, and frightened themselves instantly.Even the third prince frowned when he heard it in the dark: Xiang Fengyi——

Jia Fang didn't know that he had violated the taboo of everyone. He and Li Qingsong chased the lamp from the west of the city to the east of the city. Only then did they find the broken lamp and completely eliminated the fire hazard.

Standing in the middle of the street, the master and servant were surprised to find that there were crowds of people around him.Someone was shouting: "Go, go to the East Gate Pagoda—His Royal Highness made a bet with someone to do...do something there, experiment, yes, it's a new word, experiment!"
