After Xu Yunyan shouted loudly, Li Chengdao and Li Chengqian were completely indifferent.
"Master, how could this be poison? You are taking a commission from brown sugar. Can't white sugar be extracted from brown sugar? Stop teasing us."
Li Chengqian and Li Chengdao observed quite carefully.
Xu Yunyan scratched his head, "When did your two highnesses come?"
"I've been here for a while. I went to see Master's wife first and left a maid to serve. Then I came here. I happened to see what Master was doing here."
"Hey, look at what your two highnesses said. What kind of improper behavior did my master do? Isn't it all for the Tang Dynasty to make more money?"
Xu Yunyan said this, and Li Chengqian and Li Chengdao looked at him.
"Didn't Master say that this white sugar is produced by the royal family? The white sugar you have developed can really bring benefits to the Tang Dynasty?"
Xu Yunyan's heart skipped a beat. This sugar was not given to Chai Shao for survival in the first place. It was just that the method of making sugar he provided was quite crude. The loss was relatively high and the output was not that high. Xu Yunyan was thinking in his heart. this matter.
However, although Xu Yunyan was thinking about such things here, he still said to Li Chengdao and Li Chengqian.
"You two highnesses, don't worry too much. The process of refining white sugar this time is quite simple, and the yield is quite high. It is more beautiful than the yellow white sugar of General Chai, and it will definitely sell for a good price."
When Xu Yunyan mentioned selling money, Li Chengqian and Li Chengdao looked at each other.
"Why is this white stuff so expensive? White salt is quite expensive, and this white sugar is also very expensive?"
Xu Yunyan knew that the white salt they were talking about was the kind of fine salt that the princes and ministers of their court ate, which was obtained by further processing sea salt.
As for ordinary people, most of them eat simple, unprocessed sea salt or pre-processed coarse salt, which is quite cheap.
"Your Highnesses, we can sell it to dignitaries and wealthy merchants. Both white sugar and brown sugar are extracted from sucrose. To put it bluntly, white sugar and brown sugar have similar functions. Poor people who cannot afford white sugar can eat red sugar. Yes, it’s just that the high-end market collects benefits for Datang, not to mention their costs are not high.”
"I see."
Li Chengdao and Li Chengqian finally understood what Xu Yunyan was doing and nodded here.
"It turns out that Master thought about it in such detail."
Just after Li Chengdao and Li Chengqian finished complimenting Xu Yunyan, Xu Yunyan looked at the two highnesses in front of them and bowed their hands to them again.
"Since your two highnesses are here and have brought their maids to take care of this humble wife, I can't thank you enough."
When Xu Yunyan said this, Li Chengdao and Li Chengqian hurriedly began to be polite.
"Are you praising us or hurting us? Everyone knows that Master, you are pure and have high ambitions. You don't even have a servant at home. You have to rely on your sister to do everything. The two of us apprentices didn't even think of finding two for you. This maid is really our fault. All the benevolence, justice, etiquette, wisdom and faith we have learned every day have been in vain. Now I know how to find a maid for the master, or I should wait here to make amends to the master."
When Li Chengdao and Li Chengqian said this, Xu Yunyan was also a little moved. This was the prince's grandson, and he actually accompanied him, even though he was one of their nominal masters.
However, the masters of the prince and grandson have gone to heaven and earth, and quite a few of them are famous masters. How can I be so virtuous and capable? Just a warrior.
Just after Xu Yunyan exchanged a few polite words with the two of them, Li Chengqian smiled and said to Li Chengdao.
"The two of us met the master by chance, and brought some of the cheap white sugar we made back to Grandpa Huang. Grandpa Huang knew that it was so easy to make so much white sugar, and it was even more beautiful than what my uncle made. , I don’t know how happy I will be and how I will reward Master.”
"Yes, yes, this is very good."
After Li Chengqian finished speaking, Li Chengdao hurriedly walked outside with some sugar.
"Master, let's go to Grandpa Huang to report our work first. Don't worry, this is what Master did. We will definitely get all the credit for Master and won't let Master's hard work go in vain."
After Li Chengdao and Li Chengqian said this, Xu Yunyan nodded, "Okay, then it's all done."
After Li Chengqian and Li Chengdao left, Xu Yunyan couldn't help but feel a little moved when he saw the maid they left here caring for Mei Jingjing.
"I am also a fool. Even though I am seriously ill, I can still arrange for others to go out and choose two maids to take care of Mei Jingjing, right? Why didn't I consider it?
Is it because I don't realize that this is the case, or is it my later thoughts that are causing trouble here? But this time I was really wrong. "
After saying this, Xu Yunyan walked into the room and looked at the two people who were lying quietly for Mei with sweat on their foreheads.
Seeing the two people's meticulous work, Xu Yunyan said to them.
"The two girls are busy. Letting the two of you take care of my wife so hard is really a burden on the two girls."
The two girls couldn't agree with what Xu Yunyan said. There was a difference between superiority and inferiority, so they could only do this.
After Xu Yunyan said these words, the two people hurriedly put down what they were doing and stood up to salute.
"This slave has met the Marquis."
After they said this, Xu Yunyan remembered.
"Yes, I am now a Marquis, a very high title, and the next level up is a Duke."
Xu Yunyan clapped his hands casually, "You don't have to be so polite. You are here to help me. I should do this."
Xu Yunyan said polite words, and the two girls looked at each other here, and everyone could see the message in the other's eyes.
"I didn't expect that the high-ranking Marquis, General Yunhui, who was a third-rank official and had great military achievements, could be so kind. Although he is not a high-ranking official in Chang'an City, such a young Marquis is so kind to the two emperors' grandsons. Your closeness will definitely be indispensable for your success in the future, not to mention being so kind to others, thinking about it, he is the best choice for a wishful husband."
Xu Yunyan ignored the strange looks the two girls looked at him, and said to them again with a fist in his arms.
"Thank you, two girls, for taking care of me here. I happen to have something to do, please."
Xu Yunyan said such an inexplicable sentence again and left quickly. He just saw that Mei Jingjing was very hot, but he felt distressed when he saw her.
Saltpeter ice production must be put on the agenda as soon as possible.
To make ice from saltpeter, you first need to collect saltpeter.
Xu Yunyan shouted when he had a plan.
"Zhang Hong!"
Zhang Hong quickly came to Xu Yunyan again.
"General, don't you know what your orders are?"
"Zhang Hong, I have a mission for you. Find me a large amount of saltpeter."
"Ah, saltpeter? What is this?"
Zhang Hong was a little confused at this time. He didn't know what the saltpeter was.
"This, this...that, that..."
Seeing Zhang Hong struggling here, before Xu Yunyan could ask, Zhang Hong gave up.
"General, is this saltpeter an ore or something special?"
Hearing Zhang Hong's question, Xu Yunyan immediately began to explain here.
"Indeed, this saltpeter is a kind of material. The most common place is the white powder in the corner of the stable."
"I know what it is. Fire saltpeter is fire saltpeter, right? An accelerant for igniting fires?"
"So this is called fire saltpeter. Then go get me some and see if it is the same thing as the saltpeter I mentioned."
Xu Yunyan suddenly realized.
"Okay General, I'm going to get it now, but this stuff smells quite strong. What are you going to do when you get up?"
"Does it smell very strong?"
A question mark flashed over Xu Yunyan's head, which was invisible of course. Here he looked at Zhang Hong in confusion. Zhang Hong saw Xu Yunyan looking at him in confusion and spoke cautiously.
"It must have been very smelly in the stables mixed with the smell of shit and urine."
Hearing this, Xu Yunyan thought for a moment, "You're right, this is it. Go and collect it for me. The more you can collect, the better."
Zhang Hong felt a little embarrassed at this moment.
"My Lord General, can we change it to something else? The smell of collecting this saltpeter is quite strong. Is it really suitable?"
"Is there anything suitable or inappropriate? Didn't you just say that you could find something for me as long as I said it? How can I explain it now?"
Regarding Zhang Hong's reluctance, Xu Yunyan was ready to use his identity to suppress him.
