Treat everyone in the inn well, Qin Shaochu left here, returned to the Qin Mansion, saw Duan Si just at home, and asked Duan Si to help him buy the caustic soda, Duan Si nodded, and left the Qin Mansion, and when Duan Si left, Qin Shaochu accompanied Xuanxuan to play in the courtyard.

In the afternoon, Duan Si bought back the items Qin Shaochu needed, "caustic soda" Qin Shaochu nodded, said to Xuanxuan, and then found it in the house, "Cup, soup spoon, wooden chopsticks, medicinal wine, vegetable oil, ......etc."

Coming to a small room, Qin Shaochu put these things on the table and began to make them.

Qin Shaochu first poured the water slowly, the water dissolved the caustic soda, then put the water and caustic soda in a container, and then kept stirring, and it didn't take long for the water to become transparent. Foam and heat appeared. ”

Then add the oil while stirring, and when the caustic soda is completely dissolved, gradually put the oil in while stirring. Blend with a blender for fifteen minutes.

Seeing this, Qin Shaochu poured in the medicinal wine, continued to stir carefully, stirred for a while, and waited for the red wine to be completely and evenly distributed. At this time, the liquid began to thicken gradually, and Qin Shaochu stopped.

At this time, Qin Shaochu took out an iron box that he had found in advance, opened a small hole in it, injected this ye body into it, and then sealed the small hole.

Seeing that it had been completed, Qin Shaochu breathed a sigh of relief and opened the door, Xuanxuan saw Qin Shaochu walking out, so she hurriedly ran over, saw Qin Shaochu had an iron box in his hand, and said curiously: "Brother, what is it at this time?" ”

Qin Shaochu smiled slightly, "At this time, the secret, Xuanxuan, you will know the day after tomorrow." ”

Hearing that her brother didn't say anything, Xuanxuan was a little disappointed, "Okay, brother, you have to show me tomorrow." ”

"Well, okay"

Qin Shaochu found a big box, put the tin box inside, and then returned to the yard.

On the third day, Duan Qiuyue came to Qin Shaochu's house, Xuanxuan saw that Sister Duan was coming, so she hurriedly grabbed her; "Sister Duan, let's go, let's go find my brother."

Duan Qiuyue looked at Xuanxuan's anxious appearance and was very curious, "Xuanxuan, is there something wrong with you?" So anxious to find your brother. ”

Xuanxuan pouted and said, "Sister, I, I saw my brother holding a small box the day before yesterday, I asked him what it was, but he didn't tell me"

Duan Qiuyue smiled slightly when she heard Xuanxuan say this, and at the same time became more curious in her heart.

Xuanxuan came to Qin Shaochu's door and couldn't wait to knock on the door: "Brother, brother, are you awake?" ”

Qin Shaochu opened his eyes and heard Xuanxuan's shouts outside, so he said, "Xuanxuan, wait for my brother, get up immediately." ”

After a while, Qin Shaochu opened the door and saw Duan Qiuyue also standing at the door, "Qiuyue, you're here." ”

Duan Qiuyue smiled, "Hmm"

Xuanxuan hurriedly said at this time: "Brother, brother, what is the box you took that day, Xuanxuan wants to see it." ”

Qin Shaochu smiled and said, "Okay, my brother will take you to see it immediately." ”

Letting Xuanxuan stay in the courtyard with Duan Qiuyue, Qin Shaochu walked in front of the big box, took out the tin box inside, and found a knife and came to Xuanxuan's side.

Immediately, he slowly cut open the tin box with a knife, and a small yellow piece appeared in front of Xuanxuan and Duan Qiuyue, Xuanxuan looked at the small yellow piece, and asked curiously: "Brother, what is this, is it to eat?" It smells so good. ”

Qin Shaochu shook his head and said, "Xuanxuan, this is not for eating, this is for use,"

Xuanxuan was disappointed when she heard that it wasn't for food, "It's not for food, what's the use?"

Qin Shaochu touched the little yellow piece, found that it was a little hard, nodded, and then asked his subordinates to bring a basin of warm water, and the knife gently cut on the little yellow piece's body, dropping some fragments.

Qin Shaochu wet his hands in the water, and took these fragments in his hands, and suddenly foamed on his hands, Xuanxuan saw this and opened her eyes.

Duan Qiuyue also saw this bubble, and her eyes widened.

Looking at the expressions of the two, Qin Shaochu smiled slightly, and after a while, Qin Shaochu cleaned his hands in his hands and brought them to Xuanxuan's side, "Xuanxuan, do you smell it, is it fragrant?" ”

Xuanxuan's head approached Qin Shaochu's hand and sniffed: "Brother, it's really fragrant" "I, I want it too, I want it to be fragrant on my hand."

Okay, after speaking, Qin Shaochu also washed his hands for Xuanxuan, Xuanxuan smelled the aroma on her hands and smiled sweetly

Duan Qiuyue looked at the happy appearance of the two of them, and said, "This, what is this?" ”

Hearing Duan Qiuyue's question, Qin Shaochu smiled and said, "Qiuyue, this thing, I call it soap," "You also saw it, this soap can be used to wash your hands, face, and body." ”

When Duan Qiuyue heard this, she nodded and said, "We in Chang'an also have something that can be used to wash our bodies, which is made of natural honey locust mashed and mixed with spices."

Qin Shaochu nodded and said: "Qiuyue, I know that thing, but it's not as convenient as my soap, you see my soap, you can take it with you at any time, it can be said to be a must-have item for home travel."

Duan Qiuyue thought for a moment and nodded, "Indeed, your soap smells very fragrant, and it is easy to listen to on your body, but will you sell it?" ”

Qin Shaochu shook his head, "Qiuyue, I don't plan to buy it for the time being, you have also seen it, my soap has not completely hardened for the time being, and I will have to wait for at least half a month,"

Duan Qiuyue was a little disappointed, "Oh, okay then. ”

Looking at Duan Qiuyue's appearance, Qin Shaochu understood Duan Qiuyue's thoughts in his heart, and held Duan Qiuyue's hand, "Qiuyue, although I don't sell this soap for the time being, I can give this soap to you." ”

When Duan Qiuyue heard this, she was originally a little disappointed, but she suddenly got better, looked at Qin Shaochu and hurriedly said, "This is what you said." ”

"Of course, what's yours is mine, what's mine is yours, we're a family."

Hearing Qin Shaochu's words, Duan Qiuyue blushed and hummed quietly.

Duan Qiuyue left Qin Shaochu's house in the evening, watching Duan Qiuyue leave, Qin Shaochu came to the room where soap was made that day, and after thinking about it for a while, Qin Shaochu began to do it.

was busy until the second half of the night, Qin Shaochu made seven pieces of soap, looking at these seven pieces of soap, Qin Shaochu nodded with satisfaction, and after these boxes were placed, Qin Shaochu returned to his room.

Early the next morning, Duan Qiuyue came to Qin Shaochu's house and asked Xuanxuan, Xuanxuan smelled the fragrance on Duan Qiuyue's body, and said: "Sister, you are really fragrant, you used the one that my brother gave you, incense...."

Duan Qiuyue hugged Xuanxuan and said with a smile: "Xuanxuan, it's soap, my sister went back and used it last night, it's very fragrant."

Xuanxuan nodded heavily, "Well, it's very fragrant." ”

"Hee-hee, is your brother up?"

Xuanxuan shook her head, "I heard from them that my brother went to bed very late last night, so he hasn't gotten up yet."

Duan Qiuyue nodded, "Okay then, let's wait for him to wake up in the courtyard,"
