"Okay, this group of people is skillful enough."

"For this pipe, I have to sell it for three or five jin of money..."

"Are you robbing? Three or five jin, are you crazy? This pipe is not worth the price even if it is pure gold! You have to know that my money minting in the Tang Dynasty is only 300,000 jin per year."

"I changed my mind, so I helped sell this thing, and the name is Liulangkouzhi. Do you think the items made by the prince are worth the price?"

"It sounds so disgusting, it seems like something is coming out of my mouth..."

"Hehehe, if this is the case, it can be sold more expensively. You don't know that the big girls and wives in Jiangning City are celebrating your reputation all day long..."

Li Yu ignored him and asked Yingxue to clean up a painting table and use it as a workbench. The painting table is ten feet long and four feet wide, and it was actually made of a whole piece of nanmu.

He remembered that this was given by Li Jing on his birthday two years ago. Every day of writing and painting was written on this case. Because it was a tabletop of a whole wooden board, there were problems such as cracks and cracks, which means that there were such luxurious objects in the palace.

But now this thing is about to become the workbench of the physics laboratory, "a waste of resources."

Taining proposed three things in one breath, face fat and hand fat were actually similar. Li Yu also had a general idea, but it involved a relatively complex chemical reaction. It took a while to collect the materials. Let's put them on for a while. This lipstick lip balm is simple. I thought that the tube would be a little more troublesome, but as a result, the existence of Jin Work became easy to solve.

He ordered Yingxue to put a few lit silver frost charcoal into a small charcoal stove, and put a copper basin containing half a basin of clean water on it. Li Yu broke off two small pieces of beeswax, weighed three cents with a small rod scale, threw it into a small porcelain bottle, and put the porcelain bottle into the copper basin. At this time, the water in the copper basin was a little boiling, and the beeswax in the porcelain bottle began to melt gradually.

"This is called a water bath. Heating with water. Beeswax is sensitive to the heat. It will smell burnt when you pass by. This is something for the ladies of a family. Be sure to keep improving!"

Li Yu explained casually that Li Jingchang changed his past smile and looked carefully at this moment and listened carefully. Li Yu wanted to touch his head and praised him, "What a good student's material."

When it was basically melted, I took out a piece of linen cloth that was quickly tightened and put a bottle under it. This was about to filter it.

The beeswax we brought were all natural products, and there was no industrial pollution at all, but the debris pollen in the beehive, and even wood chips and grass sticks all have to be disposed of.

Li Jingqian's face was serious, as if the one in his hand was not the fine linen cloth, but the imperial seal. Yingxue looked funny and said, "Liulang, wait a moment, I will take something to save the effort from Baoning King."

Taking advantage of Yingxue's entry, Li Yu patted Li Jingcheng's shoulder: "You stand here and don't walk..."

After saying that, he ran aside and poured himself a cup of tea.

Yingxue ran to the outside room, brought her embroidery basket, took out a bundle for embroidery and said, "If Liulang wants to filter the beeswax residue with fine linen, this thing can save some effort."

As he said that, he took the fine linen from Li Jingqian's hand, took the tension rack, and put the fine linen on it tightly, and a simple fine hole sieve was made.

Li Jing smiled with her eyebrows and eyes, "I'm so lucky, even the people in the room are so clever."

Li Yu sighed to Yingxue, "I just want to torment him for a while, you're good. Turn your arm out. Taining got a bowl of pearls a few days ago and moistened you a little. That's the best Liaozhu, it's not cheap."

"I asked her not to give her any favors. You haven't taken any of the benefits of this guy. You've helped him. Be careful that he's sold him and he's helping him count the money?"

"You are a villain who judges a gentleman's heart. If I enjoy cherry blossoms and snow objects every now and then, I'm afraid you will turn against my uncle immediately."

"Are you poor?" Jing scolded with a serious expression and blurted out

"What does this mean? It sounds very strange. Could it be that it is written in other countries?" Li Jingchang looked confused.

"Yes, this is Tocharis..."

The languages ​​spoken by Kucha, Cheshi and other ethnic groups in the Western Regions of the Tang Dynasty are all Tocharis.

Li Jingcheng "..."

"Nephew, what does this Tochari mean?"

"Don't care about these details..." Li Yu laughed awkwardly.

Then he ignored him and put a cloth on the porcelain bottle containing the melted beeswax. After thinking about it, he put the empty bottle in a copper basin with a stretcher on it.

"Stop talking nonsense, hold on to the strap, look at it." Pour the melted beeswax onto the fine linen cloth. This is said to be linen cloth, but it is not very tightly woven, and the mesh is a bit big, just like gauze from later generations.

Li Yu said: "The weather is cold and beeswax is sticky, so you can only choose this slightly loose linen. If it is too tight, it will turn into a wax cloth. It is useful to wear it with rainproof..."

Since it was operated on the copper basin in the water bath, the beeswax did not solidify quickly, and most of them passed through the sackcloth smoothly and became much clearer.

"You, do it as I just did..."

Li Jingqiang curled his lips and had to do so. Yingxue covered her mouth and smiled.

It was at this time that the two of them really regained the innocence and curiosity of the thirteen-year-old child. Li Yu seemed to have returned to the physics experiment class in junior high school. He thought of his intimate classmates who brought starch and dripped dilute hydrochloric acid, and put it in his mouth, saying that he wanted to taste the taste of glucose...

Fortunately, the teacher discovered it early...

At the moment, Li Jingyan pouted, his hands were still shaking, and he was holding a porcelain bottle to filter beeswax. He looked somewhat similar to that careless classmate...

After filtering three times, the beeswax has become very clean, but the portion is about one-third less. Unfortunately, there is no scale measuring cup or test tube, so the dose cannot be precise. However, it is just a lip balm, so it is not as accurate as it is.

Li Yu took another porcelain bottle and handed it to Li Jingchang, "Fight the portion!"

"What's the point of calling this?"

"If you ask you to call me, you will be called. Why do you say so much?"

"Tsk..." Li Jingqiong had no choice but to do it honestly. Li Yu was so proud in his heart. "Technical monopoly is good, it's good to be happy when it comes. He made Ya dare not go west when going east, and let Ya jump off the building and not dare to walk the stairs, tsk tsk"

"Two taels and five cents."

"The attitude is good, and the child can teach you." Li Yu's ugly face was undoubtedly revealed at this moment. It was really satisfying to look at Li Jingqian's look of being dissatisfied but unable to kill him.
