When Wang Xijun heard Li Yan mention the reward, hesitated and said, "Your Highness, you have found someone who knows how to make glass, but something went wrong..././"

"Oh, what's the problem?" When Li Yan heard that the person who could make glass found it, he was immediately shocked. The bottle and mirror of the perfume she gave to her mother before were all made of crystals, not only yields

Very low and extremely expensive. The perfume he produces now can only be stored in opaque porcelain bottles, and mirrors cannot be produced in large quantities. So Li Yan was very eager to make glass, you must know that glass

Products are a good thing. They can not only be used as mirrors, bottles and other daily necessities, but also into chemical instruments and various optical instruments, such as telescopes, glass windows and other things that Li Yan wants to make the most.

Hearing Li Yan's question, Wang Xijun sighed and told the situation of the person who knows how to make glass. No one in the Tang Dynasty could fire glass, although the local glass and glass firing process was very

Similar, but if you want the glass craftsmen to burn glass, it is not something that can be done in a short time. However, it doesn’t matter if there is no one in the Tang Dynasty. There are many Hu people in Chang'an City, and many of these Hu people are from Central Asia.

In Persia and other places, there is one of the origins of glass, so Li Yan believed that some of these Hu people would definitely know the skill of firing glass, so the main object of the reward was these Hu people.

Sure enough, shortly after the reward was issued, a Hu merchant came to apply for the job. However, unexpectedly, the Hu merchant himself did not burn glass, but he had a slave who had worked in a local glass workshop in Persia before.

In the past ten years, I have been very proficient in the materials and firing of glass.

Wang Xijun didn't care about slaves or not, as long as he could burn glass, he was very generous and wanted to exchange the reward of thousands of guan coins for Hu Shang's slaves, but he didn't expect that the other party was not only greedy, but also very smart. He said that the reward of thousands of guan coins

It is only required to provide technology for firing glass. If he only gave him a thousand mondays, he could ask the slave to provide the technology for glass, but the slave was still his. If he wanted both technology and slaves, he would definitely come out again.

One thousand guan is the price of this slave itself.

Wang Xijun became popular at the time of hearing this. Although what Hu Shang said sounded very reasonable, a mere slave costs 1,000 guan. This is obviously a blackmail. People who specialize in selling slaves in Chang'an City are ordinary slaves.

Only a few cents of money, the most expensive Kunlun slave is only a few dozen cents of money. I have never heard of any slaves that can be sold for more than one hundred cents of money, but now this Hu merchant is actually a lion. A slave actually costs 1,000 cents of money.

, What is this not blackmail? Of course, Wang Xijun could not agree, but Hu Shang's attitude was also very firm, so the matter was stalemate now.

After listening to Wang Xijun's statement, Li Yan measured it in his mind. Although as long as there is glass firing technology and the craftsmen are left to study, it will definitely be able to burn glass, but the manpower and material resources are definitely spent on it.

Qianguan. In addition to the time delayed, the cost is even higher. So from the cost perspective, it is definitely worth spending Qianguan to buy a slave who is proficient in glass firing. After all, as long as this person is there,

The materials are suitable. You can make the glass in the shortest time. But when you think of spending 1,000 guan to buy a slave, Li Yan also felt a little depressed. It was not because he felt sorry for the 1,000 guan of money, but because he watched it as a pit.

But I still have to jump down. This feeling of being cheated is really unpleasant.

Li Yan is not a person who is willing to suffer losses. When he rolls his eyes, he thinks of a good idea. He smiled wickedly and asked Wang Xijun to tell Li Yong about this. Then he asked Li Yong to talk to the Hu Shang. When Wang Xijun heard this, he immediately understood.

Li Yan meant, laughing at Li Yan for being shameless. Who doesn’t know that Li Yong’s temper is so full of temper in Chang’an? If Hu Shang dared to ask for a random price from him, Li Yong would definitely let the other party know what a playboy in the Tang Dynasty is?

However, Li Yan was still a little worried about Li Yong's ability to do things. He wrote a letter to him personally, telling him that he could be fooled and that it would be fine to hit people, but the slave must be obtained intact. If he did it, he would do it.

After this, the glass factory he opened will give him 10% of his shares for free.

"Your Highness, it's okay to forget the fireworks last time, but this time you even want others to intervene in glass. Do you know how much profit this percentage of shares is?" Seeing that Li Yan wanted to give it to Li Yong Yisheng in his letter

Shares, Wang Xijun said with heartache.

"Haha~, you little money fan, why haven't you forgotten the fireworks until now?" Li Yan looked at Xijun's heartache look, and intimately reached out and scraped her nose.

"How could I forget it? That's fireworks. During August Day, you didn't see how many people rushed to buy it as soon as the fireworks were launched? But you are fine. Not only did you not produce it yourself, but you also didn't even register a patent.

, It was actually given to the general in the palace as a prisoner, and he didn't want a penny, you..." Wang Xijun had long been used to Li Yan's frivolity, but when he said this, he looked heartbroken and almost pointed at Li

He scolded him for being a prodigal son with his nose.

"Hehe, why do you have only money in your mind?" Li Yan rubbed Xijun's head with great difficulty. Although he was smiling on his face, his heart hurts, but there was no way. He would give him gunpowder sooner or later.

Heat weapons will develop sooner or later, and the formula of gunpowder must be kept confidential. He doesn't want to pass the formula of gunpowder to several surrounding countries. If they create any new weapon, it will be the Datang in the end.

The army suffers?

But the fireworks were specified by his emperor's father, and Li Yan wanted to keep the gunpowder formula confidential, but if the fireworks were put in his house for production, it would definitely not be kept confidential. After all, craftsmen were all used to help.

There is no word for trust. It is not safe either. Li Yan didn't want to fall asleep one day, and suddenly he flew into the sky with a loud bang.

So Li Yan thought about it for a long time, and finally he finally thought of a solution, which was to find Yuwen Hu, the master of the supervisor, to provide him with gunpowder formula and fireworks production methods, and to provide him with craftsmen who already produced fireworks.

and workshops, so manpower and venues are not a problem. In addition, as a government agency in the palace, it is not very difficult to keep confidential. Therefore, they are left to produce fireworks. In order to solve Li Shimin's request, they can also keep confidential.

The only disadvantage is that Li Yan can't make a penny on fireworks.

Everything has its advantages and disadvantages. It is necessary to keep it confidential and not delay production. It always costs a little! Li Yan can only use this sentence to comfort himself and Wang Xijun, although Xijun really wants to know why Li Yan insists on using gunpowder

The formula is kept confidential? Unfortunately, Li Yan just didn't say it, but she had no choice but to give up.

After reporting these things, Wang Xijun no longer stayed. It was enough for her to be busy for a long time when dealing with the Wang family in Taiyuan and the expansion of perfume production. She could also use this busyness to make Li Yandao.

I forgot about the marriage. Although Xijun never had any extravagant expectations for the position of the princess, whenever I saw the lively scene of lights and decorations in Prince Liang's Mansion, I couldn't help feeling aroused in my heart, and sometimes even my eyes were astringent.

Just after Wang Xijun was sent away, Li Yan picked up the Three Kingdoms and was about to continue watching, but the servant came to report that his uncle Duan Lun, who was the Minister of Works, had come again. Li Yan did not dare to neglect and was preparing to change his clothes and go to the front to greet him.

But unexpectedly, Duan Lun couldn't wait at all, so he actually asked his servant to take him to Li Yan's study.

"Haha~ Liulang, I'm so happy!" Duan Lun shouted at Li Yan with a smile as soon as he came in. His old face turned red with excitement, and even his beard was raised high.

When Li Yan saw the other person's appearance, he immediately guessed a rough idea and said with a smile: "Haha, Liulang congratulations to uncle, finally researched the steel filling method. If you have made such great achievements in your office, you will definitely let it go.

My father is very happy, and with the curved plow that was presented by your hand a month ago, I believe it is not an exaggeration to be named a prince in the future."

"Where is it? This is all the reward for worshipping Liulang. Thanks to the theory you proposed, let alone the curved plow, it was completely created by you. I have also taken advantage of you.

!" Duan Lun said hurriedly and modestly. He was really convinced by Li Yan now. Not to mention the newly developed steel filling method, the invention of the last time the curved plow surprised him and all the officials of the Ministry of Works.

.

Last time, Duan Lun was very dissatisfied because the steel filling method provided by Li Yan was just a theory. Finally, Li Yan agreed to him and gave it to Duan Lun as compensation. So a few days later, Li

He brought the bell plow that had been made by the department and demonstrated to them the use of this new type of plow. As a result, this plow that was flexible and extremely labor-saving. The animal power immediately caused Duan Lun's

Pay attention to.

After that, Duan Lun immediately ordered the craftsmen to imitate it and sent it to a farm near Chang'an for trial. As a result, the user responded unanimously that this new plough was much stronger than the previous straight plough. As long as it was properly operated, one person could even have more than one season.

After several acres of land were opened, Duan Lun finally felt the truth and presented the Quyuan Plough to Li Shimin and asked for great promotion. As an emperor who attaches great importance to farming, Li Shimin was also very happy to see the effect of the Quyuan Plough. Now

Different from the next year, Duan Lun, Li Yan and a number of officials from the Ministry of Works have also been awarded a lot of rewards.

Just now, the steel filling method has been completed. When the steel production of the Tang Dynasty increases several times in the future, Duan Lun's name will leave a strong mark in the history books. Duan Lun also thought of it.

This is why Li Yan is so enthusiastic about this.

Seeing Duan Lun so happy, Li Yan happened to have something to ask for him, so he smiled and said, "Uncle, look at my nephew who spared no effort to help you. Now I happen to have something difficult to ask for you. You see
