"yes!" Li Xiu nodded blankly, isn't it just a pancreas, is it necessary to make such a distressed expression?

"Loser! I...... I ......" Ma Ye was really angry this time, and his whole body was trembling, this was the first time Li Xiu had seen him so angry.

"Uncle Ma, what's wrong with you, isn't it just a pancreas, I'll go to Chang'an to buy a piece and pay you back another day!" Li Xiu was also a little strange at this time, Ma Ye, who is usually a very generous person, how could he be so angry because of a piece of pancreas?

"Buy? Where do you go to buy it? Don't look down on this thing, but in fact, it is extremely complicated to make, only the royal family and a few big families have mastered the method of production, and it is said that the output is very small, and I usually can't buy it with money, I only have two pancreas in my hand, or the princess gave it to me, usually I don't even want to use it, but I didn't expect to be used by you, a loser, to bathe the dog. Ma Ye finally yelled with a sad and angry face at this time.

Although the royal family can make pancreas, but due to the limited production, it is only supplied to the royal family for its own use, and occasionally it will be rewarded to ministers, although Ma Sanbao is also an important general, but has not been rewarded, and he can only be given to him by Princess Pingyang if he wants to use it, which shows the preciousness of pancreas.

"It's just a pancreas, isn't it made of pig pancreas and soybean flour, although the production of pig pancreas is limited, but it's not so much that even you, a general, can't use it?" Li Xiu asked in disbelief at this time.

"How can it be so simple, I heard that pancreas are made with a lot of precious spices, and the production is very complicated, and it may fail if you are not careful, so the number of finished pancreas is very small, usually I am reluctant to use it when I take a bath, only when I encounter a major festival, it will be used to clean my hands, you are good, even for the dog to bathe, I said, what are you not a loser?" Ma Ye said angrily again, it was nothing to give Li Xiu a piece of pancreas, but he was angry that he didn't know how to cherish it.

Li Xiu couldn't help but feel stunned when he heard this, and he wouldn't have thought that a pancreas that was not even as good as soap would be so precious, and it seemed that the backwardness of science and technology and productivity in this era far exceeded his prior estimates.

"Uncle Ma, I really didn't know that pancreas were so precious in advance, but you don't have to feel distressed, it's a big deal that I'll compensate you in two days!" Li Xiu explained first, and then reassured that it was just a piece of pancreas, and it was a big deal that he made a piece of soap to compensate Ma Ye, and he still remembered the saponification reaction in middle school chemistry class.

"Huh? Don't tell me, you even know how to make pancreas, do you? Ma Ye, who was originally angry, heard this, but glanced at Li Xiu with some suspicion and said, if others said so, he would definitely think that the other party was bragging, but Li Xiu, the little guy, broke his expectations several times, and now he doesn't know how much ability this kid has not revealed.

"Hehe, you'll know that then!" Li Xiu deliberately sold a pass at this time, and even if he wanted to explain, I was afraid that Ma Ye would not understand, so it was better not to say it.

Seeing that Li Xiu was so secretive, Ma Ye also scolded with a smile, and then did not ask any more questions, and began to beckon him to eat vegetables, but just after a few bites, Ma Ye suddenly asked with some surprise: "Boy, have you eaten all the eggs on your plate?" ”

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

"What about eggshells?" Ma Ye asked with wide eyes.

"Little three eaten!" Li Xiu's face did not change.

"Then why is your belly so bulging?"

"It's over!"

"......" Ma Ye was speechless, he had never seen someone who was so brazen after being exposed.

Although there were some small episodes in the middle, but it did not affect Ma Ye's interest, and when the birthday banquet was over, he was already drunk, and was helped down to rest by Liu Xiaoge, who took care of him, Li Xiu did not drink, so he escaped, when he came out of the living room, he saw Lao Qi standing outside the door, and Li Xiu walked over and took out a few eggs and handed them over: "Lao Qi, please eat eggs!" ”

Looking at the eggs handed to him, Lao Qi's face, which had always been unwavering, twitched obviously, and then shook his head very concisely: "It's hurt!" ”

"Hurt from eating?" Li Xiu looked at Lao Qi with some sympathy when he heard this, it seems that Ma Ye just said that there were not enough eggs to eat before, and he couldn't believe it at all.

Leaving the princess's courtyard, Li Xiu did not answer, but turned around and went to the Li family Zhuangzi, and when he met the children in the Zhuangzi, he would give each person an egg, everyone in this era can give birth, don't look at the five families in the Zhuangzi, but there are many children in the Zhuangzi, more than 20 eggs are sent, it is not enough, several older children have given eggs to their younger brothers and sisters, which makes Li Xiu a little embarrassed, and tells them to bring them snacks tomorrow.

In the end, Li Xiu came to Mr. Liu's house, and saw that Mr. Liu's wife and Su Niang were all in the courtyard with bamboo baskets, and there were several baskets of bean sprouts that had been sent to the city next to them, all of which were to be pulled to the city to sell tomorrow morning.

"Uncle Liu is busy, is there anyone who will embarrass you again during this time?" Li Xiu walked into the courtyard with a smile and greeted Boss Liu.

"You're here, Lord, please take a seat!" 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 courtyard, and then continued, "Since you helped us teach those people a lesson last time, no one has ever troubled us during this time, and the people who usually buy vegetables are also much more polite to us, and even the Wuhou in the vegetable market has taken good care of us." ”

Li Xiu also smiled a little when he heard this, this situation was also expected by him, after all, although Chang'an City is big, but for the circle of the powerful, there is no secret at all, Wang Junkuo's people want to rob the bean sprouts business, but they were taught a lesson by Ma Sanbao of the Pingyang Princess Mansion, this kind of thing is enough for the magnates to gossip for a long time, and even everyone knows that the bean sprouts business is backed by the princess's mansion, which one who is not long-sighted dares to find trouble?

"Uncle Liu, call me tomorrow when you go to sell bean sprouts, I'm going to Chang'an City to buy something." Li Xiu spoke again, since he promised Ma Ye to give him better pancreas, he couldn't break his promise, so he decided to make some soap, but I don't know if he can buy all the materials in Chang'an?

Hearing that Li Xiu was going to enter the city, Boss Liu also agreed, and then asked his mother-in-law to prepare the meal, but Li Xiu had just eaten, and his stomach was still supporting, so he hurriedly excused himself, and finally left Liu Lao's family.

In the early morning of the next day, it was still dark outside, Li Xiu was woken up by Boss Liu, and then he got dressed and followed Boss Liu to push the bean sprouts, and walked for an hour before coming to the city gate, at this time the eastern sky was just white, and there were already a lot of people gathered outside the city gate, and after waiting for about a cup of tea, the city gate was finally opened, those who entered the city went to the right side of the city gate, and those who went out of the city went to the left side of the city gate, the two sides did not interfere with each other, and Li Xiu and they also entered the city very smoothly.

After entering the city, Li Xiu and Boss Liu separated from them, originally Boss Liu was not worried that he was alone, so he had to follow Li Xiu, but Li Xiu knew that the people who sold bean sprouts had not been enough, and if Boss Liu followed him, then the people who sold bean sprouts would be even more insufficient, so in the end he refused his kindness and wandered around Chang'an City alone.

Speaking of which, Li Xiu has traveled to the Tang Dynasty for a long time, and he lives on the edge of Chang'an City, but it is the first time to enter the city, so he is also very interested in this legendary ancient capital, and he went to the legendary Suzaku Street first, but was also taken aback by this street about one hundred and fifty meters wide, such a wide street can be used as an airstrip.

Although it is early in the morning, Suzaku Street is already very lively, and the pedestrians are flowing endlessly, but it is a pity that there are no shops or stalls selling breakfast on both sides of the street, because Chang'an City strictly follows the structure of the market, and business can only be done in the square or other fixed areas, and other places are not allowed to do business.

Li Xiu walked along Zhuque Street all the way to Leye Fang, then turned west and walked for a while, and finally came to the legendary West Market, Chang'an City has two special commercial square areas, namely the East City and the West Market, and most of the people who live around the Middle East City are powerful families, so they mainly deal in all kinds of luxury goods, and most of them are jewelry and other shops.

The West Market is more civilian, there are everything sold here, plus the starting point of the Silk Road is Chang'an, and it is convenient to enter and exit the city gate from the West Market, so the West Market here is mixed with Hu and Han, Persian carpets, Tianzhu gold ornaments, wine from the Western Regions, etc., all can be found here.

It was already noon when Li Xiu came to the West Market, you must know that Suzaku Street alone is ten miles long, and he is walking and strolling, so he walks very slowly, and he hasn't even eaten breakfast until now, he wanted to find a restaurant to eat something, but he was attracted by the smell of Hu cakes on the street, and immediately took out a few pennies to buy a Hu cake, which was sandwiched with mutton and eaten while walking.

There are not many materials needed to make soap, the first is oil, the second is alkali, that is, sodium hydroxide, this thing is very rare in nature, but it can be generated by the reaction of flour alkali and lime, so Li Xiu first went to buy some lime, and then went to buy flour alkali, this thing is called cold stone by the Tang people, and they already know how to put flour alkali into flour, and the pasta that comes out of this way is more strong and delicious.

The last is to buy oil, Li Xiu knew before that the oil in this era of the Tang Dynasty is very expensive, before he made fried bean sprouts, it was difficult to find some oil, and then Liu Dayan went to his father-in-law's house as a butcher to come to a little lard, and the villagers were reluctant to light the lamp at night, because they wanted to burn tung oil, although tung oil could not be eaten, but it was also very expensive.

Li Xiu came to the grain and oil store and asked, and found that only vegetable oil is sold here, and if you want animal oil, you can only go to the vegetable market, and animal oil is much more expensive than vegetable oil, and there are not too many requirements for oil to make soap, so Li Xiu decided to choose cheaper vegetable oil, and 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 used as lamp oil, and the other is edible sesame oil, referred to as sesame oil, which is actually sesame oil in later generations.

Because sesame oil is edible, it is much more expensive, and tung oil is relatively cheap, but this thing is poisonous and may cause dermatitis in contact with the skin, so Li Xiu can only choose sesame oil, and when he asked about the specific price, he was startled again, a small jar of sesame oil is so much, no wonder the people of Datang did not invent stir-frying, this is simply not affordable!
