However, white sugar is more valuable than brown sugar, and Li Xiao also needs to purify and decolorize.

The method used by the Tang people was to decolorize the yellow mud, but the technique was relatively simple, and the method used by Li Xiao was the method that only started in the Song Dynasty.

The same is decolorized with yellow mud, but the Tang people use the mud cover method, the operation first heat and evaporate, concentrate to a viscous state, and then pour it into a funnel-shaped tile bowl, seal the lower mouth with straw in advance, after two or three days, the lower mouth of the bowl is sealed by crystallized sugar.

At this time, the bowl is put on the pot, and the syrup is evenly pressed with yellow mud cake, and then the yellow mud gradually penetrates into the syrup, and gradually precipitates to the bottom after absorbing various colored substances, so the plug grass is set out, and the mud gradually drip into the pot below with the sugar density, after a considerable time, the decolorization process is completed, the adobe is removed, and the upper and middle parts of the bowl become the best white sugar, and the bottom is still black brown sugar.

This decolorization process has been used until the Song Dynasty, it is said that in the Song Dynasty, there was a sugar craftsman in Quanzhou because of the rain wall collapse sugar sugar, and later dug out the sugar from under the collapsed wall, but found that the brown sugar turned into white sugar, after research, then found the yellow mud decolorization method.

This method is simpler than the previous drip method, adding an appropriate amount of yellow slurry directly to the syrup, so that the decolorization effect is better, better white sugar can be obtained, and the efficiency is also greatly improved.

However, this method has not been discovered for a long time, and it is true that not every craftsman dares to do this kind of thing by mixing yellow mud directly into the precious syrup, and if it were not for the unexpected discovery later, I believe that this method would not have appeared so quickly.

Li Xiao transferred the yellow mud and water to the yellow mud, and after repeated debugging, he obtained the yellow mud with the most appropriate proportion, and took the neutralized and clarified syrup and mixed it with the yellow mud.

Watching a can of good syrup water slowly covered with yellow mud water is indeed a little distressing.

After mixing the yellow mud, what you need to do is to wait, wait for the yellow mud to absorb the various colored substances in the syrup and then slowly precipitate to the bottom.

After a long wait, Li Xiao left the space directly and returned to the bedroom.

It was a long time in the space, but it didn't take long outside. When I opened the door, it was still noisy and lively outside, and the women had already begun to grind yellow noodles with millet, preparing to make yellow nests with noodles.

Xue Wu arched his hand, "San Lang is admirable." ”

"What is there to admire, they are actually also affected by my Li family, otherwise they would not have been without overnight food, and they will not leave when my Li family is in trouble, take care of my family for me, and now that I am back, I naturally have the obligation and responsibility to repay them. As the saying goes, the grace of a drop of water is reciprocated by a spring, and no matter how much I do now, it is nothing. ”

"Affectionate and righteous, a manly man." Xue Wu gave up his hand again.

"Love is worth a thousand gold, and there is no faith and no righteousness." Li Xiao said indifferently.

"Just now I heard the Zhuang Shangren talk about your family, this Zhang family is indeed a bit excessive, I can't imagine that a local tyrant in the countryside can be so lawless, people can't stand it, a certain has some relationship in the official face, if Brother Tai doesn't mind, I am willing to help." Xue Wudao.

Li Xiao was a little moved when he heard this, he had already seen that this Xue Wu was not simple, riding a war horse, leading a veteran, and he was not ostentatious, he was definitely not a nouveau riche tyrant, he must be a nobleman.

At the feet of the Son of Heaven in Chang'an, there are many nobles, and it is normal to meet someone casually, such a character, if you want to help him, it is really a matter of raising your hands to deal with a small local tyrant like the Zhang family.

However, Li Xiao didn't agree immediately, why should others help him.

Besides, this Xue Wu came suddenly, and the real purpose is not clear.

"At the beginning, the Zhang family calculated step by step, and the things were done very strictly, not leaking, but I am afraid that there are no flaws, even if it is said in the official face, there is not enough evidence, but I am afraid that it will not be easy to get it." Li Xiao said.

Xue Wu just smiled, "There is no impermeable wall in the world, no matter how tightly it is done, there will be flaws, as long as you check, there is no problem that cannot be found." Especially for such a small local tyrant in the countryside, there is a way. ”

Li Xiao smiled, what Xue Wu said was also reasonable. The difference in identity is too great, and people will drop ten times with one force.

"If Gorou can really help, Li San is grateful."

Xue Wu shook his hand, "Don't rush to thank you, it's no problem for me to help you, but it's conditional." Remember the bet I made to you earlier, don't you have nothing to bet on? In this way, if you can take out the whiter frosting candy, then you will win the bet, what about me, I will naturally admit the gamble and lose, and then I will personally come forward to help you solve the Zhang family, and how about giving your Li family a fair? ”

"If I can't take out the sugar, can Xue Gongzi help it?"

Xue Wu looked taken for granted, "If you can't take it out, that's a liar, why should I help a liar?" ”

"Okay."

"And when are you going to get the whiter frost?"

"Today."

·······

On the road outside the village, the little overlord Zhang Chao rushed over with a large group of household servants.

"Fence me off, don't let anyone go."

·······

Lijiazhuang chickens fly and dogs jump!

"San Lang, it's not good, the little overlord is here."

"We're surrounded."

Several dealers looked panicked, and the name of the little overlord was arrogant and murderous, and it was still very famous in the small place of Lanxi.

"Don't be afraid, I'm here." Li Xiao frowned, the conflict with the Zhang family would happen sooner or later, but he didn't expect it to come so soon.

Da Biao had already picked up two pig-killing knives and rushed over, "Damn, who ate the bear's heart and leopard gall and dared to come here to make trouble?" ”

Tie Zhu and others also rushed over with long sticks, everyone had rebelled in Jiangnan, joined the rebel army, and even fought with the official army.

With Li Xiao's backbone, and seeing Da Biao's bravery, the other Zhuang men also calmed down a lot, and those with hoes and shovels each copied the guy and followed Li Xiao.

"Hahaha!"

The little overlord Zhang Chao broke in with a group of swaggering people, and when he saw Li Xiao standing there, he couldn't help but let out a smug laugh.

"Isn't this Brother Li from Yangzhou, I thought that Brother Li had already taken the money back to Yangzhou, I didn't expect you to be here, and even more unexpectedly, you are still my old acquaintance. I really didn't recognize you before in five years. ”

He swaggered up and stared at Li Xiao left and right, "Don't say it, now that you look at it like this, the more you look at it, the more familiar you become, it's really Li San, damn it, Lao Tzu really didn't recognize it for a while." ”

"Li San, you shouldn't come back, what do you say you came back, you might as well die outside. Today, your Grandpa Zhang is going to let you see with your own eyes how I avenged you for breaking my leg back then. My Zhang family not only took away your Li family's property, but today, I will also arrest your wife and your sister-in-law back as concubines. Even this ancestral grave of your family, I will level it. ”

Li Xiao stepped forward.

"Zhang Chao, Hugh is rampant, do you think there is no king law in this world?"

"Wang Fa? In this Blue Creek, my Zhang family has the final say! Here, beat this Li San to death with a stick, and catch those two little girls back for me! ”

"Hahaha!"

An abrupt laugh interrupted Zhang Chao's arrogant words.

"It's so ridiculous, I can't imagine that there are such arrogant people here, in the dignified land of Gyeonggi, at the feet of the Son of Heaven, it's really ridiculous." Xue Wu said with a sneer on the side.

Zhang Chao glanced at him, "Which crotch is not clamped, and such a thing as you came out?" ”

Xue Wu was stunned and furious!
