Chapter 9 Low-key Development
……

"Awen, what happened just now?"

At the door of the pharmacy, Mr. Zhu Jiu, who saw what happened just now, asked Wu Wen.

Wu Wen briefly recounted what had happened.

As a person from the lower class, Jiu Ye had no idea about the conflicts between those people at the top. He just felt that Wu Wen received the reward from the prince, which was a great favor from heaven.

"Your Highness is truly kind. This silver cake is enough for us to use for a year."

After expressing his feelings, Master Zhu Jiu took Wu Wen to the grain, oil and grocery store to buy daily necessities.

"Shopkeeper, what's the price of corn?"

Just when Jiu Ye was buying corn, Wu Wen saw maltose being sold on the counter with the price marked on a wooden sign next to it.

The cut, dark sugar cubes cost ten cents each.

The frosted sugar in a porcelain bottle was almost as expensive as silver, one ounce of silver for one ounce of sugar.

"My goodness, the price difference is too big."

Just as Wu Wen was secretly complaining about the two prices, an idea suddenly popped up in his mind.

They are both sugar, but there is such a big price difference between the two. Why not buy some brown sugar yourself, refine it into white sugar, and then sell it to make a profit from the difference?
The more he thought about it, the more he thought it was feasible. Wu Wen said to the waiter beside him, "If I buy a lot of brown sugar, can you give me a discount?"

"How much can you buy?" the waiter asked.

"I want... ten dollars." Wu Wen answered while thinking.

"If you want ten dollars, I can give you two cents off."

"You don't have much less, so how about ninety cents?"

"This is not possible..."

Just as Wu Wen was bargaining with the waiter, the other side's shopkeeper and Master Zhu Jiu came up to them at the same time.

"Awen, you want to buy some candy? Ten pieces are too many. You can't finish them. If you want to buy some, just buy one." Master Zhu Jiu advised.

"Sir, if you buy ten pieces, I can make the decision and charge you five cents less. Too much is really not acceptable." The shopkeeper on the other side also said with a smile.

"Master Jiu, I bought this candy for other uses." Wu Wen whispered beside Master Jiu.

Then he said to the shopkeeper: "Then wrap it up for me."

"okay!"

Hearing this, the waiter immediately responded loudly and started packing things quickly.

"Sir, your candy."

Pay in one hand and deliver in one hand.

After buying everything else, Wu Wen and Zhu Jiuye left.

When the two passed by a butcher's shop, Jiu Ye stopped and bought a piece of pork to improve their meal.

Afterwards, the two did not stop and hurried back, finally returning home before dark.

"Ouch, I'm so tired!"

After putting down his things, Wu Wen started to make a fire and cook without taking a rest.

First, blanch the pork you bought in boiling water. I have never seen such a big piece of meat before, so it can be considered a luxury today.

However, Wu Wen soon stopped laughing.

Because the pork was so smelly, putting it in boiling water felt like boiling urine, and the smell was so pungent that he could hardly open his eyes.

"Ugh~"

"Oh my god, how can I eat this?"

Wu Wen really felt like throwing it away along with the pot.

At this time, Master Zhu Jiu smelled the smell and came over. He looked calm and said, "The meat is almost ready. Take it out and cut it into slices and you can eat it."

"What? Just eat it like this?" Wu Wen looked at him in disbelief.

"Yes, why haven't you eaten pork before?" Seeing his strange expression, Master Zhu Jiu asked in confusion.

Wu Wen smiled awkwardly. Of course he had eaten pork before, and he had also eaten boiled pork slices like this, but he had never eaten pork as smelly as this. How could he eat it without using spices to suppress the taste?

But Wu Wen could only think about precious things like spices.

It seems that I won’t have this blessing.

Take out the pork cooked in boiling water from the pot, cut it into slices with a knife and arrange them.

Finally, clean the pot carefully and add water to cook rice porridge.

While eating, Wu Wen watched Jiu Ye eating the boiled pork slices with relish and couldn't help swallowing his saliva.

"Eat!"

Seeing that he hadn't moved his chopsticks, Jiu Ye looked at him curiously, then pointed at the white meat on the plate and said to him.

"No, no, I don't like eating meat. Master Jiu, if you like it, you can eat as much as you want. This is all yours."

Wu Wen drank the rice porridge in the bowl with a guilty conscience.

Seeing how strange he was, Jiu Ye didn't ask any more questions and continued to pick up the pork and put it in his mouth to chew.

After dinner, we cleaned up and went to bed to rest.

Lying on the bed, Wu Wen first looked up through the window to admire the night view of the sky.

Then, as soon as I closed my eyes, a picture of a small courtyard at night emerged in my mind.

Everything in this courtyard is stored information transformed from Wu Wen’s memory.

In the center of the courtyard, there was a figure standing. Under the moonlight, he slowly moved his body and practiced Crane Fist.

"It's almost done. With more time to polish it, this Crane Fist will be basically finished."

The night passed.

The next day, Wu Wen got up to the sound of birds singing outside the window.

After practicing boxing with Master Zhu Jiu, Wu Wen did not sort out the medicinal materials, but took out the brown sugar he bought yesterday.

Wu Wen planned to use the yellow mud decolorization method to refine brown sugar into white sugar.

The yellow mud decolorization method is actually a very advanced skill.

Although it sounds simple, it seems that the impurities and pigments in brown sugar can be removed by the adsorption of yellow mud to obtain white sugar.

But in fact, this process is much more complicated than imagined.

When Wu Wen was surfing the Internet in the past, he saw many bloggers trying to use the yellow mud decolorization method to turn brown sugar into white sugar, but they all failed without exception.

So Wu Wen went to look up some information and found that these people did not really understand the principle of yellow mud decolorization and started to try blindly. How could this be successful?
The yellow mud here is not ordinary yellow mud. The yellow mud used in sugar making is actually yellow clay, which is alkaline.

The yellow mud water is not just mud. The correct way to make yellow mud water is to add water to the yellow mud and stir it, then clarify it and take the supernatant as the yellow mud water.

Wu Wen put brown sugar into the pot, added an appropriate amount of water, then lit the fire and started heating while stirring constantly.

When boiling sugar, you must pay attention to controlling the heat. Do not overcook it, otherwise it will easily become gelatinous, lumpy, or even turn into caramel.

The key to making sugar is stirring. By constantly beating, bubbles are produced in the syrup, increasing the contact area with the air, so that the water in the sugarcane juice evaporates quickly.

Wu Wen made a funnel-like device using a clay pot and prepared a bundle of straw.

He inserted the straw into the mouth of the funnel with the tip of the straw facing down and the roots of the straw facing up, and then poured the boiled and concentrated syrup from the roots of the straw, letting the syrup stick to the straw.

Then, he began to pour yellow mud water on it, trying to increase the contact area between the syrup and the yellow mud water as much as possible until the syrup was completely melted.

Afterwards, Wu Wen kept stirring the mixture of yellow mud water and syrup.

As the stirring progressed, some impurities floated up along with the foam.

He continued stirring until the foam was fine and lumpy, then scooped out the impurities.

The remaining liquid is allowed to settle naturally.

After a period of sedimentation, Wu Wen took out the supernatant for evaporation and crystallization.

In the end, what you get is sugar as white as snow.
