Li Dahai's stewards were very immoral, they bought the shop next to the Wang family's business at a high price, and also put up a banner with the inscription "His Royal Highness the Prince's industry, the cheapest coal in Chang'an, the people can afford to burn it."

Those who had the money to buy coal couldn't help but be attracted by the banners and went to see what the prince's coal would look like.

Wubenfang, just before the Imperial City, the people who can live here are either rich or expensive, and naturally there is no shortage of money to buy coal.

Seeing a guest circling around the coal, the steward Lao Zhang greeted him.

"Do you want to buy coal? You can rest assured, this is the prince's property, and it will definitely not sell fakes, it is all fine coal, and it is durable to burn. ”

Wearing linen gloves and looking at the coal, the housekeeper-like guest nodded: "It's all good coal, the most rare thing is that there is no cinder, it's all lump coal, and the housekeeper has your surname?" ”

Lao Zhang said with a smile: "The villain is free from your surname Zhang, you are right, those who come to buy coal are generally used to burn coal stoves, and they are rarely used to make fires." Cinders are not resistant to burning, so naturally they will not be added to the commodity. Oh, by the way, you haven't consulted yet, right? ”

"You just call me Lao Qi, I'm Princess Changguang's housekeeper, counting, we are also a family, can the price of this coal be lowered a little more? When you let me go back, I will take credit for it. ”

Seeing that Steward Qi took out the heavy money bag in his sleeve, Lao Zhang immediately smiled: "Don't worry, His Royal Highness the Crown Prince sells things to his aunt, it doesn't matter if you suffer a loss, as long as you help us publicize it on the way back!" ”

After speaking, the two of them entered the store talking and laughing.

Compared with the overcrowded Prince shop, the Wang family's shop, which was still crowded the day before, is considered to be crowded today. Even if there is, it is because the price of coal in the prince's place is too low, and he wants to compare. After sampling and checking, they will still choose the prince's.

What made them most angry was that the cinders from the prince were not thrown away, but made into briquettes and sold to commoners.

Civilians don't care about the hard burning of briquettes and the amount of waste, what people care about is the burning resistance of briquettes, and fifty big briquettes for a penny are clearly given away for nothing!

For three days in a row, what made the steward of the Wang family sad was that no one came to his door, and even if there was, he would ask for a return. According to others, the same coal is sold so expensive, isn't it clear that he is cheating people!

"Steward, we've got to figure out a way! If it goes on like this, let's go back to our own clan, and we won't be able to escape the family law! ”

The family law of the big family is more frightening than the punishment of the official family. The punishment of the government is for corporal punishment, and unless it is a repeat offense, no one is killed. But the family's family law is loose internally and strict externally, and inferior people like them who are not directly related to the Wang family, but are just attached to work here, can only bear it honestly if they are killed, and it is useless to report to the official.

The steward of the Wang family naturally knew what the family law was, and closed his eyes in pain: "Let's reduce the price first, reduce it to the same as the prince's, and the old man will write a letter to the family, asking the family to send his direct children over." ”

The servants, who had received the steward's order, were overjoyed and immediately sent messages to the shops selling coal everywhere to lower the price together. Although the price reduction made a small profit, it was sold anyway. Coal is different from other commodities, it is only valuable in winter, and when the winter passes, there is a lot of rain in summer, and if the protection is not in place, it will be completely scrapped.

The Wang family's actions were naturally vigorous, but to their surprise, they had lowered the price to the same price as the prince's, but the customers still ignored them, and would rather queue up and buy the prince's coal.

"You deserve it! I said that the wealthy family is rich in thieves, it turned out to be a black-hearted price increase, covering his head to make money at home! Or His Royal Highness the Prince, look at it, the Wang family has changed the price! ”

"My brother is right, hmph, the Wang family is black-hearted, and the rich businessmen can't afford to sell coal, so I can only watch the poor and small households. Look at how atmospheric the prince is, although the price of coal is not low enough for us to afford, but he has made a briquette. There are a lot of them at home, and they don't worry about burning them all winter. ”

"That's it, I also heard that when the prince fell and injured his leg, it was the Wang family who preached that the prince's leg was not good. However, no one has caught evidence in this matter, otherwise, why didn't the prince ask the Wang family, but just exposed the black heart of the Wang family? ”

"Where did this old brother get the news? What's wrong with the prince's leg falling, to put it mildly, he has no legs, and I also support him as the emperor! ”

....

Dialogues like this continue to appear all over Chang'an. Under the conscious guidance of the members of the secret guard, a trend of public opinion that "the Wang family is a black-hearted person and the prince is benevolent" is taking shape.

Li Chengqian, who was in the courtyard of No. 001, saw the report sent by the secret guard, and his stomach hurt with laughter.

Throwing out a topic and mobilizing public opinion, this hand, I don't know how many people are playing in later generations, he just borrowed it, but he didn't expect it to be effective in the Tang Dynasty.

It is no wonder that Liu Bang wants to kill the white snake, and the Yellow Turban Army also wants the slogan "The sky is dead, the yellow sky should stand". The people who spend all day digging in the land like nothing more than gossip, and the behavior of "following the clouds" cannot be avoided even in such an open era in later generations, let alone now.

Although fooling the people made him feel a little guilty, if he wanted to deal with the Wang family, he could only do this.

If it is said that in the coal business, it is his strategy to find a way to make the Wang family lose money, and it is too ridiculous, and the heritage of the wealthy family is not something that can be damaged by one or two business failures. His real purpose is actually to attack the reputation of the Wang family.

Fame is a thing, whether it is the common people or the princes and magnates, they are all regarded as treasures, and as for families like the five surnames and seven wangs, it is the existence of the root of life.

"Hmph, I don't know what Wang Ying's old guy will look like when he learns that the Wang family's reputation in Chang'an is stinky!"

Throwing the secret report into the brazier and burning it, Li Chengqian decided to continue practicing his archery skills.

Damn Feng Ang obviously agreed to teach, but after entering the academy, it was like a pervert seeing a beautiful woman, and he was more attentive to learning than a student. originally decided to leave to go back a year ago, but it was delayed again and again, so that the Lingnan clan thought something had happened to him, and sent Feng Zhiyu to spy in the name of paying tribute. As a result, the one who came to inquire about the news was also trapped in the academy, and only sent the old servant back with tokens and letters to report his safety.

Although Feng Ang has no time, there is still no shortage of coaches, Li Chengqian.

Although Ashina Xue can't open a five-stone bow, her archery is very good. With her as a sparring partner, her archery skills have improved.

The cold wind blows in winter, which interferes with archery a lot, but the more such an environment is, the more you hone your skills.

After an arrow hit the nine rings, Li Chengqian blew his stiff hand and continued to shoot the next arrow.

"Eight out of ten arrows can hit the target, which is already very good, why do you have to shoot the heart?"

Exposed to the cold wind, Zhang Yun knew the snot elder, but Ashina Xue didn't care at all.

Distracted, the arrow hit the ground, and Li Chengqian looked back helplessly and said: "There is an idiom in the Central Plains called 'keep improving', do you know? Besides, if I don't practice archery well, what should you do if you look down on me again? ”

Hearing this, Ashina Xue blushed a little. When she first came to the Tang Dynasty, she really felt that the prince of the Tang Kingdom was a waste. After all, when she was a child, her father told him that the Han people only had a little courage in the generals and soldiers who fought in battle, and those in power, I was afraid that the Turkic warriors would be so frightened that they would pee their pants with a loud shout.

As for the royal family, it is even more cowardly, fighting a war will only let the generals go up, governing the country will only let the ministers do it, and they will only have to eat, drink and have fun. The crown prince, the person who will become the emperor in the future, will definitely not be much better.

However, after this period of getting along, she probably knew that what her father said was not entirely right. At least, she found that the prince of Tang Guo was not a wine bag and rice bag.

His swordsmanship is very good, it's not a showmanship at all, and his fist and foot skills are not bad, the eunuch named Zhang Yun is very powerful, but even so, he can hold on to Zhang Yun's hands for a long time. Although archery is incomparable with the Turkic warriors, looking at the way he is now engrossed, he knows that after one or two pieces, archery will be successful.

Looks have never been the point, what she admires the most is his desperate treatment of injuries. It's reckless, but it's also courage.

Unconsciously, she realized that this seemed to be the Ruyi Langjun she was looking for.

Although, this is the prince of the Han people, and he is not destined to remain friendly with the Turks.

It wasn't until the last arrow in the quiver hit the target that Li Chengqian nodded with satisfaction and told Yu Tai to send Ashina Xue back, and he planned to go to Qingque to have a look.

Originally, it was a site for experimenting with hydro and wind power, but since Li Tai joined, it has been constantly expanding. When I was researching ordinary things, I was in the Faculty of Engineering, and when I was researching important things, I went to the secret testing ground.

Wind power, in the end, is still subdued, now the giant hammer of hydraulic wind power has been sent to the Ordnance Superintendent, Ouyang Shuo of the Ordnance Superintendent came to the college to thank him after testing the performance of this thing, and wrote an excerpt to ask for credit for the College of Engineering. According to him, with these two things, Datang's armor-making and smelting capabilities can leap more than five times.

In the cold winter season, Li Tai did not spend the winter in the Wei Palace, but shrank in the laboratory of the Institute of Engineering to fiddle with iron and wood. Although, there are more than a dozen coal stoves in the laboratory ....

"Qingque, what are you doing here?"

Seeing that Li Tai was holding two pieces of iron and gesturing, and was not busy with them, Li Chengqian asked curiously.

Putting down the iron piece in his hand, Li Tai was about to get angry, and when he saw that the person who came was his imperial brother, he turned into a laugh.

"Brother Huang, you came just in time, when you were plowing in the spring, didn't you say that you can combine ploughing, sowing, and soil cultivation together, so I want to make such a plough stick.

The Eastern Han Dynasty Cui Wei has a book of "Political Commentary", saying that at that time there was a cocoon car for planting, composed of three cocoon feet, there are three ditch openers under it, when sowing, with a cow to pull the cocoon car, the cocoon foot in the flat land ditch sowing, at the same time to cover and suppress, in one fell swoop, save time and effort, its efficiency can reach nearly 20 acres of daily planting.

But I went to Sinong Temple and asked, there is this thing, but the drawings have been lost. After inferring the structure of the cocoon according to the records, I think that even if there is, it is difficult to spread it because the people still like to sow seeds by hand, and the seeds sown by the cocoon are too many and wasteful. ”

Seeing that Li Tai was talking endlessly, Li Chengqian was shocked. You must know that this kid is only eleven years old now, so he thinks about it so thoughtfully. The people like to sow seeds with their hands, and he can't be self-taught, he definitely went to the farmer's house to ask. No matter what it is, it will only be welcomed if it caters to the market demand, which I didn't expect Li Tai to understand now.

"Qingque, did you go to the farmer's house and ask? Otherwise, how do you know that farmers sow seeds by hand for fear of wasting seeds? ”

Li Tai smiled: "That's natural, since the car is going to be promoted to the people in the future, I don't ask how their opinions will come true." Don't talk about this, Brother Huang, I went back to the palace yesterday to visit the queen mother, guess what news I learned? ”

"If you have something to say, tomorrow I will go back to the palace to ask my father and queen mother to say goodbye, maybe my son will have to move back to the East Palace, even if you don't say it, I can know."

When the old gentleman was still there, he could still live here in the academy, but now that the old man is gone, as the crown prince, he must return to the East Palace as soon as possible. After all, the crown prince is to stay in the East Palace.

Seeing that the imperial brother was not hung up on his appetite, Li Tai could only continue to break the news: "The queen mother said that the candidate for the concubine has been determined for you, guess whose family?" ”

Is the concubine confirmed? If nothing else, this candidate should not change.

Li Chengqian smiled helplessly: "The eldest daughter of the secretary Cheng Suqian? ”

Hearing Li Chengqian's faint tone, Li Tai was not calm.

"The queen mother said that the daughter of the Su family was secretly received by her, and she strictly ordered me not to say it, brother Huang, how do you know?"

After confirming the conjecture from Li Tai's mouth, Li Chengqian immediately lost interest.

Although history has changed, the concubine of the East Palace is still the Su family.

However, judging from the selection of the concubines of the East Palace, including the concubines of the King of Wei, the emperor's father obviously does not want to marry a powerful and famous family anymore, and what he prevents is the dictatorship of his relatives. However, the princess still has to marry into a large family, especially a new family, which is one of the means for the emperor to win the hearts of the people and consolidate his power.

"What do you think, Brother Huang? But I also want to see what Su looks like in advance? Don't worry, my brother hasn't forgotten what you helped me, hehe, why don't we visit Su's house tomorrow? ”

Seeing Li Tai's sinister face, Li Chengqian shook his head helplessly, and said seriously: "Qingque...."

"It's good that we both know such a thrilling thing, but don't tell anyone else!"

Li Tai immediately became kind, never mentioned this matter again, but continued to drum up his own iron piece.

In order to develop a cocoon that could sow seeds in a uniform amount, he had experimented with a variety of structures.
