In the afternoon, the sun was shining in the back mountain of the palace, with birds singing and flowers fragrant. The important craftsmen of the palace gathered here.

......

An hour ago, Prince Kang brought his concubine Zhou Li and Princess Yongming with him, and Shiyu arranged a grand reception.

Prince Kang probably said something to his grandmother seven. This time the meeting was obviously much more restrained than yesterday, probably about his identity and other things.

Li Xingzhou didn't care too much, and brought Gillian and Shiyu to entertain the couple warmly.

Then Zhou Li prepared to show them her family-born glass making technology in the back mountain.

She just brought a bucket of delicate river sand, a small white bag, a peculiar iron pipe, and several small deep ceramic furnaces, brown, cylindrical, and very deep.

Li Xingzhou personally brought something to her, and everyone came to the kiln in the back mountain. The weather was very good in early spring, and there were many people present.

Zhao Si was still trying to improve his cannon, while Qiuer was focusing on the manufacturing of the steam engine, so she didn't come.

Zhurong was in charge of these kilns, Tien Niu, Guan Zhong and other craftsmen rushed over curiously after hearing the news and came to watch. The kilns in the back mountain were Zhurong's general managers, graphite crucibles for firing steel, jade bottles for producing general brews, and porcelain bottles for perfume.

This job is not only stable, but no longer has to think about catching work like before. It also has a lot of work. The business in the royal family is good, so they have endless work to solve the problem of eating for dozens of people from all over the Zhu family.

The most important thing is that the royal family has slowly regarded Zhurong as their own person. Every time the manager holds a "round table", he will call him, which makes him feel more belonging.

After a while, Zhu Rong used charcoal to make a fire at Zhou Li's instructions, and then, in the eyes of everyone, fixed the cylindrical small furnace with a black iron tripod to the charcoal fire.

Li Xingzhou suddenly remembered something and leaned over and asked in a low voice: "Grandma Seven, so many people are watching... It's okay." After all, this is a family-born craft or a glass-making technique, which is extremely secretive. Many people don't like to be seen by outsiders.

Zhou Li shook her head: "It's okay, my skills are useless in the royal palace. I just hope someone can inherit this skill."

Li Xingzhou nodded and smiled, "They are all the most powerful craftsmen in the royal palace."

Zhou Li said as she saw that the ceramic stove was almost the same, so she added fine sand to one of them, then added some white powder, and stirred it evenly with a clean wooden stick.

Everyone was watching attentively, including King Kang and Princess Yongming. Li Xingzhou stretched his neck and whispered curiously: "What is this white thing?"

Before Zhou Li could answer, Yue'er next to her rushed to say, "Your Majesty, you're sour."

"Sothelial?" Li Xingzhou was puzzled. He had never heard of this thing.

Yue'er hugged his arm and explained to him happily in a crisp voice: "It's something you usually use to wash clothes."

Li Xingzhou was still a little confused, but to be ashamed, he was a seven-foot man. After two years in this world, his clothes were washed by Yue'er and Qiu'er, and he took care of them all. He was really ashamed...

This life is so depraved, but... I like it very much.

Zhu Rong laughed and added: "Your daughter is a daughter-in-law, it's normal for you to not understand those things. This alkali is not expensive. It's so much to buy and sell on the market, it's cheap, and it's easy to use whatever you wash. However, the price has grown by 20% or 30% this year, and I don't know what's going on."

Zhurong said that everyone saw it, which also aroused King Kang's feelings: "Yes, I'm also surprised. I don't know how much I used this thing since I was a child, so why has the price increased this year?

There are many people in my house. No matter how cheap the goods are, the more you buy, it will not be cheap. The 20% or 30% increase is not a small amount of money.”

When they heard these interesting things about life, they were like chatting about family matters, they actually felt like an old man next door.

But he still doesn't know what this "spoon alkali" is.

Yan Shen, who happened to be resting next to him, returned to the palace from the military camp today, came over and took a look: "Prince, why don't you ask General Di about this thing, he must know a lot."

"Why?"

"Because the military also needs a lot of syringe, he took a lot of syringe in Luzhou last time. Now it is used in the military every month, not just washing and washing." Yan Shen said.

Li Xingzhou's curiosity suddenly came up, "What else can I do?"

Yan Shen shook his head and spread his hands in a daze, saying, "I don't know, I just care about training the army, and Di Zhi is in charge of major military affairs."

"Is he in the palace?" Li Xing asked,

"Here, I'm back with me." Yan Shen nodded.

"Why didn't I see him?"

"I don't know, after the prince and the princess came, he suddenly said something was wrong, so he went to the backyard to help Mr. Zhao test artillery." Yan Shen didn't think so much, and he didn't know how to speak without any restraint. As expected, Princess Yongming next to him heard this and his face turned bad.

Li Xingzhou opened his mouth and wanted to say this, but finally waved his hand and said, "Go and find him."

Yan Shen nodded and hurriedly called Di Zhi.

Li Xingzhou understood that Di Zhi was avoiding his sister-in-law Princess Yongming.

After a while, Di Zhi came and bowed to everyone. Li Xingzhou then asked about "sigh-alkali".

He asked, and everyone looked over.

When Di Zhi saw that everyone looked at him, he bowed and said, "Prince, this thing is used to make skins in the army."

"All armors in the army require leather, but the leather collected from hunters cannot be used directly. We call them raw leather. They need to be processed with oral alkali to make mature leather. This kind of leather can be sewn into armor. The repair of armors in the army also requires leather, so a large amount of oral alkali is also required."

After hearing Di Zhi's words, Li Xingzhou suddenly realized and had some speculations about the ingredients of "salpalmic acid".

"Just Zhurong just said that the price of oral alkali has risen this year. Do you know what's going on?" he continued.

Di Zhi smiled and said, "Prince, although this thing is produced in Jingguo, it is not much. It is originally agglomerated, like mineral deposits, but it is mostly exposed on the ground, and it is usually only available in places where water accumulation is accumulated in the northwest.

Most of them are white or gray-white blocks. The ones you can buy on the street are processed and cut into regular cubes. The purest cubes used by the princess are then crushed into powder. They look like salt, and they are almost pure white as snow, with the best quality and the most expensive."

Everyone was obsessed with listening and felt like they were eye-opening.

"I didn't expect you to know so much." Li Xingzhou laughed. Di Zhi was his subordinate after all, so he gave him a face.

Di Zhi just bowed his hand and continued, "Prince, my subordinates happened to see the origin when they were young, and in addition, they wanted to manage the entire army, so they used a lot.

Most of the places where the pulp alkali in our country are in the upper reaches of the Huai River, but more pulp alkalis are bought from many Tubo tribes in the northwest and the Liao Kingdom in the north, especially the merchants from various Tubo tribes. There are no people using pulp alkalis in their place, but they found that they could sell them for money by bringing them to Jing Kingdom.

So every year, many Tubo merchants even have nothing to do, collect lipid blocks, carry them to Sichuan and Sichuan, and then buy a businessman in Jingguo for money to survive.

There are also many mineral deposits of lipid alkali in the northern part of the Liao Kingdom, and they will also be sold to Jing Kingdom. Therefore, this year, the Liao Dynasty wars were in chaos, and Liao merchants could not transport lipid alkali to the south, so the price of lipid alkali naturally increased."

"So that's the case." Prince Kang nodded.

"I just said that my wife at home had complained to me several times, but I didn't know how to tell him. Now General Di has agreed that he will teach her a lesson when he goes back tonight." Zhu Rong laughed.

Listening to Di Zhi's statement, Li Xingzhou had some guesses about what this scent is, or its main ingredients.

On the other hand, after about half an hour of baking, the sand with fine powdered oleate in Zhou Li's ceramic furnace began to become viscous, and then slowly turned into a dark red semi-liquid state!

Zhurong, Tieniu, Yue'er and others stretched their necks and widened their eyes!
