Qi Ling had a rough idea of what she was going to do, but many of the materials she needed were not easy to find, so what she was thinking about now was what to use to replace those materials.

She had seen a recipe before, talking about the method of making lipstick in the Northern Wei Dynasty.

That method is to make fragrant wine first, with cloves and herbs two spices, wrapped in freshly harvested, clean cotton, and then put in the wine that has been burned to a slightly hot hand in advance, with hot wine to absorb the aroma of cloves and herbs, and the climate is different, the absorption time is not the same, or it depends on the individual's grasp.

After refining the fragrant wine, take out the cotton and spices, boil the fragrant wine with fire, and then put the butter in it little by little, and put the butter once the wine boils once, so that after putting it several times, the fragrant wine will become thick.

At this time, turn to low heat, slowly add cinnabar powder, and finally add green oil, stir until cool, it will condense into a kind of red fat, this red fat is bright in color, and the aroma is rich, the coloring is uniform, unlike ordinary cinnabar powder, easy to fade.

It's just that Qi Ling is embarrassed by the dynasty she is in now, cows are not allowed to be slaughtered at will, every cow is recorded in the government, and slaughtering will violate the law, so there is no butter to be found at all.

Besides, there's no cotton here! Yes, in this dynasty, there is no cotton!

Now Qi Ling's quilt is made of animal skin, although it is also warm, but it lacks the lightness of the quilt.

Without these two key materials, Qi Ling could not copy this method rigidly, and could only change some according to the actual situation.

She pondered in her heart that when she was in school, the chemistry teacher seemed to have mentioned a few words, saying that this method of using wine to refine aroma used the knowledge in chemistry books.

What kind of knowledge is it? Qi Ling was full of efforts to recall the situation in class at that time, and only hated himself for deserting at that time and not remembering the complete words.

At this time, two words suddenly popped out of her mind like a god: extraction!

Right! It's extraction!

The teacher said that this method is called extraction, and the common extraction solutions are water, alcohol, and oil!

Yes, you can use oil yourself!

Just like women now use osmanthus oil, they can use oil to refine the fragrance of flowers.

Therefore, you can first dry the fragrant flowers, such as the wild thorn rose, and then soak the dried flowers in oil, so that the fragrance of the flowers can be collected.

After figuring out the most difficult problem to solve, Qi Ling's mind became active.

She pondered that butter could be replaced with beeswax, which had a sweet taste, so if it was used in the production of lipstick, the made lipstick would be more popular.

Qi Ling also didn't plan to use cinnabar to provide red, although cinnabar was cheap and easy to obtain, but it would be harmful to the body, so she planned to use the juice of various flowers to mix the colors herself, and in this way, she had more choices in color and could make different colors.

Finally figured out how to make lipstick, and Qi Ling casually dried the bag of wild thorn roses.

Although we have found alternative materials, we still need to purchase them one by one, so the production of lipstick can be postponed for a few days.

Looking at the sun, Qi Ling felt that it was probably noon, and it was time to prepare lunch for the person who built the house.

At this time, the door of Aunt Zhao's house suddenly squeaked, and Uncle Zhao was helped out by Aunt Zhao.

The three workshop workers next to him had already been greeted by Aunt Zhao in advance, but they didn't look up at Uncle Zhao at this time, but they didn't make him nervous.

Uncle Zhao didn't know if it was because he was going out of the house today, so he deliberately changed into a new cloth coat and shaved his beard, looking much more energetic than yesterday.

He took a few steps forward, then gently pushed Aunt Zhao away, signaling that he didn't need to be supported, and he wanted to walk alone.

Seeing this, Qi Ling walked over, still with a sincere smile, and said, "Uncle Zhao, I was going to call you, it's almost noon, I'll take you to my house to cook." ”

With that, Qi Ling made a gesture of invitation and walked straight to the front.

Uncle Zhao nodded, probably because he had a few words with Qi Ling yesterday, he was not afraid of Qi Ling, but silently followed Qi Ling to the door alone.

In order to take care of Uncle Zhao's legs, Qi Ling deliberately walked very slowly.

Finally got out of the gate, Aunt Zhao was in the yard, watching Uncle Zhao's figure moving step by step, and felt that her nose was a little sour.

After so many years, the head of the family has finally walked out of this door, does that mean that he can really be cured this time, Aunt Zhao feels that she has some expectations for the future in her heart.

Qi Ling didn't talk to Uncle Zhao much along the way, she knew that although she was not a person to Uncle Zhao now, she was also a person she didn't know very well, and talking to him more would only make him even more afraid to speak at will.

Therefore, Qi Ling just said two sentences seemingly casually, one was to praise the weather today was really good and sunny, and the other was to see a few children in the village playing and making trouble, and said that it was really lively.

Although Uncle Zhao never spoke up, he unconsciously followed behind Qi Ling, feeling as if he was being driven by her.

Qi Ling said that the weather was good, so he looked up at the sky and felt warm from the sun.

Qi Ling said that it was lively, and he watched the children laughing and playing, and couldn't help but think of Peach Blossom's cute face when she was a child.

Aunt Zhao and Gu Jinfeng's families were not far away, but the two of them walked slowly for a long time.

When he arrived at Gu Jinfeng's house, Qi Ling was about to lead Uncle Zhao to the firewood room to cook. At this time, two villagers from the backyard who came to help build the house came over, and they came to the front yard to drink water.

Seeing these two somewhat strange people, Uncle Zhao's face turned pale, and his body couldn't help shaking, only staring at the place under his feet.

He thought that these two people must open their mouths to laugh at themselves.

But when these two people saw Uncle Zhao, they smiled kindly: "Old Zhao, I haven't seen you for a long time, come to our house to drink in a few days, remember to help me cook a few more appetizers, you don't know that I miss the taste of the appetizers you made." ”

It turned out that these two people had drunk with Uncle Zhao before, and after saying this, the two of them drank water together and continued to work in the backyard.

Before leaving, he didn't forget to say hello to Qi Ling and Uncle Zhao.

Didn't laugh at yourself? Uncle Zhao couldn't believe it, he stood there dumbfounded, wondering if he was hallucinating just now.

It turns out that not everyone laughs at themselves!
