When Zhu Bajie rode a donkey and rushed to Xue Shao's mansion, Shangguan Wan'er was about to board the carriage and be escorted back by the moon slave.

Seeing the fat Zhu Bajie climb down from the not tall donkey, Xue Shao couldn't help laughing, "Good skills!" ”

"Let Xue Gongzi laugh, I'm a lowly eunuch who can only ride a donkey and dare not ride a horse!" Zhu Bajie's eyes narrowed with laughter, and he bent down to bow to Xue Shao.

"What are you here for?" Xue Shao asked.

Zhu Bajie subconsciously glanced at Shangguan Wan'er's car, and smiled, "It's nothing, it's nothing!" I was ordered by His Highness to come and see, has the prince ever returned home? ”

Xue Shao saw his treacherous expression and knew it in his heart, it seemed that Zhu Bajie had made a special trip to Shangguan Wan'er, it can be imagined that Princess Taiping was quite worried about letting a beauty like Shangguan Wan'er stay alone with me for too long.

It's human nature. A little man and woman in love, who is not like this?

Zhu Bajie straightened his waist after the salute, inhaled the cool air with a "hiss" in his mouth, and reached out to cover his waist and hips.

"What, you still sprained yourself riding a donkey?" Xue Shao asked with a smile.

"No......" Zhu Bajie grinned bitterly and whispered: "The little one is ineffective in handling things, and he was punished with a few lashes by Her Royal Highness the Princess." ”

"Come on, get a bottle of medicinal oil for this Zhu Gonggong." Xue Shao commanded.

The servants of the house immediately agreed to go. Xue Shao and Yuenu are both good at martial arts, and it is common for them to have bruises and sprains. Yuenu had a dose of Shaolin secret recipe obtained from his father-in-law, and brewed a medicinal oil to treat bruises, and the effect was very magical.

"Ouch, how dare you do this!" Zhu Bajie was a little flattered and bowed to Xue Shao again.

Xue Shao patted him on the shoulder with a smile, "What mistake did you make, the princess wants to punish you?" ”

"It's not a big deal, it's just that when the princess went out of the palace to play, the villain was careless and forgot to bring the pancreas. After arriving at the Hibiscus Garden, Her Royal Highness wanted to bathe but did not have osmanthus pancreas, so she was punished. Zhu Bajie squinted his eyes and said with a smile, "It's okay, I'm used to it!" ”

Pancreas? Isn't it just soap?

Xue Shao's heart lit up, I have this thing in my house, and I also use it when I take a bath. I usually don't pay much attention, but I remembered when I heard Zhu Bajie talk about the term "pancreas". In the era of the Tang Dynasty, soap was a luxury, not something that ordinary people could afford. Because to make soap in the Tang Dynasty, "pig pancreas" must be used, and this material is not much after all, so the production of "pancreas" is extremely scarce. Scarcity is expensive, and "pancreas" are generally only affordable for the rich.

But I'm a science student, and I've studied biochemistry for two years, and the experiment of "saponification reaction" is something that middle school students can master. Isn't it a little too easy for me to make soap? …… And there's no need for pig pancreas at all!

When he was young, the servants in the house took the medicinal oil and handed it to Zhu Bajie.

Zhu Bajie thanked him for a while, and said in a low voice: "Why didn't the prince go to serve Her Royal Highness the princess earlier?" His Royal Highness is ...... to the prince Quite a miss! ”

Xue Shaoha's smile, this Zhu Bajie is also deeply sophisticated in the world of "reciprocating with peaches".

"You might as well report to the princess, just say, I miss the princess very much. I was supposed to visit overnight, but I was too busy preparing a mysterious gift for Her Royal Highness, so I had to go again tomorrow. Xue Shao smiled mysteriously and said, "Don't say that I asked you to entrust you, you have to go to great lengths to find out about it, do you know the way?" ”

"Xue Gongzi is really a good person, Bajie is very sincere!" Zhu Bajie knelt down with a thousand thanks,"

If his son is reprimanded, he will never give up! ”

It is a trivial matter to be punished just now, and it will be difficult to live if you are disgusted by your master in the future. There are thousands of eunuchs in the province, and it is just a matter of thought for the Taiping Duke to find someone to replace him or even bury him. Now let him offer a piece of news that can make Princess Taiping happy, it is just a flirtatious little joke for Xue Shao and Princess Taiping. But for Zhu Bajie, it may be related to the life and death of honor and disgrace in the second half of his life!

"Go ahead!"

"Farewell Childe!"

Xue Shao walked to the kitchen with a smile on his face, he hadn't played a chemistry experiment for a while, so he practiced his skills today!

As soon as he walked to the second courtyard and passed by the servant's room, Yu Hongye walked out of the room of the moon slave and stood on the edge of the corridor to worship, "Meet Xue Gongzi!" ”

"Hey, when did you come?" Xue Shao was a little stunned, "Why didn't the moon slave tell me?" That girl, it's really getting more and more silly! ”

"Autumn leaves have been here for a long time." Yu Hongye smiled and said, "Just because Childe is busy, Hongye begged the Moon Slave girl not to disturb Childe." Anyway, the red leaves are not a big deal, and it is just right to see Childe now. ”

"Oh, you're here to deliver something." Xue Shao remembered.

"Exactly, Childe might as well come and take a look." Yu Hongye raised his hand and pointed to the Moon Slave's room, where there were two large boxes.

Xue Shao went in and took a look, two hundred bras, colorful and violet, really dazzling and eye-catching.

All pure workmanship, every stitch is quite delicate and fine; The materials are all expensive Jiangnan high-grade silk and eight silk, such a silk bra is in the 21st century, and it will also be a luxury level!

"Very good." Xue Shao was full of praise, "It's really hard for you!" The timing of the delivery is just right, I'm going to see Princess Taiping tomorrow! ”

Yu Hongye sighed with relief, "Childe is satisfied, and Hongye is a little relieved." ”

"I'll take care of the rest. Don't worry, I absolutely want to make bras popular in Chang'an and the world! Xue Shao smiled confidently, changed his words, and said, "It's not unjust that you have waited so long for this trip today." Come with me, I'll teach you another way to make money today, faster than this bra! ”

"Oh?" Yu Hongye's eyes lit up, "What kind of objects do you need, Hongye will buy them immediately!" ”

"Nothing." Xue Shao smiled slightly, "I just need you to keep your eyes open and watch!" ”

Xue Shao took Yu Hongye and called the cook and two servants who were meticulous and neat, and came to the kitchen together. There may not be many other big families like Xue Fu, and the reserves of firewood, rice, oil and salt must be very sufficient. Xue Shao asked people to take out two large urns of lard, a whole tank of salt, and a few buckets of grass ash burned from the stove kang and lime water used in the construction of the house.

These things are the main materials used to make soap.

Everyone didn't understand what Xue Shao meant, and of course Xue Shao wouldn't explain it to them. He asked the servant to bring two new large iron pots, washed them repeatedly, and built two earthen stoves in the patio and set them up. Then a fire was lit to melt the lard in a cauldron, and in the other cauldron soaked the grass ash with filtered well water and added some lime, repeatedly filtered to remove the dregs, and then heated to obtain the "grass and wood lime mixture", and the alkaline aqueous solution was obtained. Although the purity is not too high, it is more than enough to make soap, and it is not a sophisticated chemical experiment.

The melted lard and the plant ash mixture are mixed together and have to be simmered for a long time to allow them to fully react chemically.

The cauldron was boiled, and the aroma of lard wafted throughout Xue Mansion. Xue Shao blasted all his subordinates away, and personally took a stirring stick and stirred slowly in the pot.

"Childe, what are you doing here?" Yu Hongye did not express his doubts until now.

"In the middle of the night, I'm hungry." Xue Shao smiled and said, "How about we stew a pot of moon slaves to eat?" ”

"Huh?" Yu Hongye was stunned.

"Uh......" Yuenu, who had just turned the corridor and walked to the side of the patio, heard it, and the whole person was stunned.

"Now that they're all back, why don't you come to help?" Xue Shao glanced at the moon slave and said with a smile.

"Yes, Childe." The moon slave came over in response to the promise, and was very surprised: Childe's body is getting stronger and stronger, and this hearing and hearing sense is becoming more and more sensitive day by day!

"Is there anything else to do, I'm here to help!" Yu Hongye is naturally not lazy.

"Yes." Xue Shao said, "You go and get a pen and paper and record each step in detail." There are also some very important points and techniques that I have dictated for you to record. ”

"Good!"

"Childe, what is this going to do?" The moon slave asked curiously while stirring the stick.

"Didn't I tell you?" Xue Shao said with a smile.

The moon slave's neck shrank, "The moon slave is not delicious, sour!" …… Also、Let's eat demons! ”

"You're righteous. Aren't you afraid that the demon will bite you? ”

"She dares!" Yuenu's face turned red, and she scolded in a hateful whisper, "I'll screw her to death!" ”

Yu Hongye took a pen and paper, and Xue Shao described in detail the small steps of this invention and the proportion of various raw materials, and Yu Hongye recorded it in detail. asked questions from time to time, and Xue Shao answered them one by one.

After a long night, Xue Shao simply asked someone to bring a tea set, and let Yu Hongye show his talent to make tea to drink. The breeze is blowing and the moon is in the sky, and the two beauties are laughing and chatting together, and it is not difficult to pass the time.

For a long time, the night was dark. The mixture in the cauldron was finally boiled to a suitable extent, and Xue Shao asked someone to move the cauldron down and put it aside to no longer heat it. In addition, the saturated concentrated brine that had been mixed earlier was poured into the cauldron.

Gradually, a layer of solids precipitated from the mixture, sodium shard fatty acids - this is not the main body of soap.

Interlacing is like separating mountains, these chemical principles are as simple as a ninety-nine multiplication table to Xue Shao, but for people in the Tang Dynasty, even a smart person like Yu Hongye is still completely confused.

After some time, a large amount of sodium hard fatty acids was resolved to form a soft coagulated solid, floating above the surface of the water. Xue Shao took the paint and the spices (ancient perfumes) that Lantian Gongzi loved to use, and added a little bit of each to the sodium hard fatty acid to modulate the color and increase the fragrance. Then skim it out of the pot, rinse it with strained warm water to remove some of the excess chemicals that are not fully reacted, and then put it in a clean basin to let it cool naturally.

"Pancreas?!" The moon slave cried out in surprise, she had seen too much of this thing in the Xue Mansion, but only then did she recognize it.

"That's right." Xue Shao smiled slightly, "Miss Yu, have you remembered everything?" ”

"This ...... I don't think I used pig pancreas! Yu Hongye was surprised.

"Not at all." Xue Shao smiled and said, "So, this is the secret recipe!" The secret ingredient to make a lot of money! ”.
