"Yes!" Li Xiu nodded in confusion. Isn't it just a pimple? Is it necessary to make such a heartache expression?

"Prodigal son! I...I..." Mr. Ma was really angry this time, and his whole body was trembling. This was the first time Li Xiu saw him so angry.

"Uncle Ma, what's wrong with you? Isn't it just a piece of pancreas? I'll go to Chang'an to buy a piece of pancreas to pay you back!" Li Xiu was also a little surprised at this time. Mr. Ma is usually quite generous, so why would he get so angry because of a piece of pancreas?

"Buy it? Where do you buy it? Don't be too conspicuous about the panzi, but it is actually extremely complicated to make. Only the royal family and a few big families master the production method. It is said that the production is very small and I can't buy it if I have money. I only have two panzis in my hand, which was given to me by the princess. I usually don't want to use it myself, but I didn't expect it to be used by you, a prodigal son, to bathe the dog." Mr. Ma finally shouted with grief and anger at this time.

Although the royal family can make pancreatic sap, due to the limited production, it will only be rewarded to ministers for their own use. Although Ma Sanbao is also an important general, he has not been rewarded yet. If you want to use it, you can only give it to him by Princess Pingyang. This shows how precious pancreatic sap is.

"It's just a pancreas, isn't it just made of pig pancreas and soy flour? Although the pig pancreas yield is limited, it won't even be useless as a general, right?" Li Xiu asked at this time in disbelief.

"It's not that simple. I heard that many precious spices are used when making pancreas, and they are very complicated to make. They may fail if you are not careful. Therefore, the number of pancreas is very small. I usually don't want to use it for bathing myself. Only when there is a major festival, it will be used to cleanse your hands. You are better, and you actually use it for bathing your dog. I said myself, "What are you not a prodigal son?" Ma said angrily again. It was nothing to give Li Xiu a piece of pancreas, but he was so angry that he didn't know how to cherish it.

Li Xiu couldn't help but feel stunned when he heard this. He wouldn't have thought that a piece of pancreas, which was not as good as soap, was so precious. It seems that the backwardness of technology and productivity in this era is far beyond his previous estimate.

"Uncle Ma, I really didn't know in advance that pancreas is so precious, but you don't have to feel sorry for it. At worst, I will pay you one more piece of pancreas in two days!" Li Xiu explained first, and then said again and promised that it was just a piece of pancreas. At worst, he could make a piece of soap to pay Ma Master. He still remembered the saponification reaction of middle school chemistry class.

"Huh? Don't tell me, you know how to make pancreas, right?" When Ma, who was angry, looked at Li Xiu with some suspicion when he heard this, he would definitely think that if others said this, he would definitely think that the other party was bragging, but Li Xiu, the little guy, broke his expectations several times. Now he doesn't know how many skills this kid has not revealed.

"Hehe, you will know this when the time comes!" Li Xiu deliberately kept it in a silence at this time. In addition, even if he wanted to explain, Mr. Ma might not understand it, so it would be better not to say it.

Seeing Li Xiu keeping it so secret, Ma Ye laughed and cursed, and then didn't ask again and began to greet him for food. However, just after taking a few bites, Ma Ye suddenly asked in surprise: "Boy, have you finished all the eggs on your plate?"

"Of course!" Li Xiu looked at the bright plate in front of him and smiled.

"Where is the egg shell?" Ma Ye asked with wide eyes.

"The mistress has eaten!" Li Xiu said without changing his expression.

"Then why is your belly so bulging?"

"I'm overeating!"

"..." Mr. Ma was speechless. He had never seen someone so shameless after being exposed.

Although some small episodes occurred in the middle, it did not affect Ma Ye's interest. By the end of the birthday party, he was already drunk and was helped by Brother Liu, who was taking care of him, to rest. Li Xiu did not drink, so he escaped. When he left the living room, he saw Lao Qi standing outside the door. Li Xiu walked over and took out a few eggs and handed them over and said, "Lao Qi, please eat eggs!"

Looking at the egg handed in front of him, Lao Qi's face, which had always been Gu Jingbubo, obviously twitched, and then shook his head very concisely and said, "I'm injured!"

"Is it hurt to eat?" Li Xiu looked at Lao Qi with some sympathy when he heard this. It seemed that Ma Ye said that he had not eaten enough eggs before.

After leaving the Princess Villa, Li Xiu did not answer, but turned to Li's village. When they met the children in the village, they would give each egg. People in this era could give birth. Although there were only five families in the village, there were quite a few children in the village. More than twenty eggs were sent, but it was not enough. Several older children gave the eggs to their younger brothers and sisters. This made Li Xiu feel a little embarrassed and told them to bring snacks to them tomorrow.

Finally, Li Xiu came to Liu Laojia, and saw that Liu Lao and Su Niang were rinsing bamboo baskets in the yard. There were a few baskets of bean sprouts that had been raised next to them. All of these bean sprouts were to be taken to the city to sell tomorrow morning.

"Uncle Liu is busy. Is there anyone else to make things difficult for you during this period?" Li Xiu walked into the yard with a smile and greeted Boss Liu.

"Master, you are here, please sit down!" When Boss Liu saw Li Xiu coming in, he hurriedly washed his hands and asked Li Xiu to go up and down the wooden pier in the yard, and then continued, "Since you taught us a lesson for those people last time, no one has ever caused trouble for us during this period. People who buy vegetables are much more polite to us, and even Wuhou in the vegetable market has taken good care of us."

Li Xiu smiled a little when he heard this. This situation was as expected by him. After all, although Chang'an City is big, there is no secret to the circle of powerful people. Wang Junkuo's people wanted to grab the Douya business, but were taught a lesson by Ma Sanbao from the Pingyang Princess Mansion. This kind of thing is enough for the powerful people to gossip for a long time, and everyone knows that behind the Douya business is supported by the Princess Mansion, who dares to cause trouble?

"Uncle Liu, when you go to sell bean sprouts tomorrow, I'm going to buy something in Chang'an City." Li Xiu said again. Since he promised Ma to give him better pancreas, he couldn't break his promise, so he decided to make some soap, but I wonder if he could buy all the ingredients in Chang'an?

When Li Xiu heard that he was about to enter the city, Liu Lao Da agreed and asked his wife to prepare the meal. However, Li Xiu had just eaten and was still full of stomach, so he hurriedly refused and finally left Mr. Liu.

In the early morning of the next day, it was still pitch black outside, and Li Xiu was woken up by Boss Liu. Then he put on his clothes and followed Boss Liu and the others to push the bean sprouts. It took him an hour to walk outside the city gate. At this time, the sky in the east was just white, and there were many people gathering outside the city gate. After waiting for about a cup of tea, the city gate was finally opened. Those who entered the city gate on the right, those who left the city gate on the left did not interfere with each other, and Li Xiu and the others also entered the city smoothly.

After entering the city, Li Xiu and Boss Liu separated. Boss Liu was worried that he would follow Li Xiu alone, but Li Xiu knew that there were not enough people selling bean sprouts. If Boss Liu followed him, the bean sprouts would be even less than enough people, so in the end he refused his kindness and wandered around Chang'an City by himself.

Speaking of which, Li Xiu had been traveling to the Tang Dynasty for a long time, and he lived next to Chang'an City, but this was his first time to enter the city, so he was very interested in this legendary ancient capital. He now went to the legendary Zhuque Street first, but was shocked by this street about 150 meters wide. Such a wide street could be used as a runway.

Although it was early in the morning, Zhuque Street was already very lively and there were endless pedestrians coming and going. Unfortunately, there were no shops or breakfast stalls on both sides of the street, because Chang'an City strictly followed the market structure, and business can only be done in the shop or in other fixed areas, and business is not allowed in other places.

Li Xiu walked along Zhuque Street to Leyefang, then turned west and walked for a while, and finally came to the legendary West City. There are two special commercial workshop areas in Chang'an City, namely East City and West City. Among them, most of the people around East City are powerful families, so they mainly operate various luxury goods, mostly with jewelry and other shops.

The West City is more popular, and there are all kinds of things to sell here. In addition, the starting point of the Silk Road is Chang'an, and starting from the West City can easily enter and exit the city gate. Therefore, the West City is mixed with Hu and Han, Persian carpets, Indian gold jewelry, Western wine, etc., all of them can be found here.

It was already noon when Li Xiu came to the West Market. You should know that Zhuque Street alone is ten miles long, and he walked while walking, so he naturally walked very slowly. Moreover, he didn't even eat breakfast until now. He wanted to find a restaurant to eat something, but was attracted by the fragrance of Hu cakes on the street. He took out a few cents to buy Hu cakes, and ate while walking with mutton inside.

There are not many ingredients needed to make soap. The first is oil and the second is alkali, which is sodium hydroxide. This thing is very rare in nature, but it can be used to react with lime. So Li Xiu first bought some lime, and then bought noodle alkali. This thing is called Hanshi in the Tang Dynasty, and they already know how to put noodle alkali into flour, so the pasta made in this way is more vigorous and delicious.

Finally, I bought oil. Li Xiu had known before that oil was very expensive in the Tang Dynasty. Before, when he made fried bean sprouts, it was difficult to find some oil. Later, Liu Dayan went to his father-in-law's house as a butcher to get some lard. At night, the merchants were reluctant to light the lamp because they wanted to burn tung oil. Although tung oil cannot be eaten, it was also extremely expensive.

Li Xiu came to the grain and oil store and asked, and found that only vegetable oil was sold here. If you want animal oil, you can only go to the vegetable market. Moreover, animal oil is much more expensive than vegetable oil. There are not many requirements for making soap oil, so Li Xiu decided to choose cheaper vegetable oil. There are many types of vegetable oil, but there are two most common ones. One is tung oil that cannot be eaten and can only be made of lamp oil, and the other is edible sesame oil, which is abbreviated as sesame oil, which is actually sesame oil from later generations.

Because sesame oil can be eaten, it is much more expensive, and tung oil is relatively cheap, but this thing is poisonous and may cause dermatitis when contacting the skin, so Li Xiu could only choose sesame oil. When he asked about the specific price, he was shocked again. A small jar of sesame oil was so numerous. No wonder the people of the Tang Dynasty did not invent stir-fry, and it was impossible to afford it!
