Not long after, the green monkey returned, followed by an ox cart with more than a dozen hemp bags on it, and the green monkey set up the cart himself, and there was a middle-aged businessman about forty years old in the car.

Qing Monkey is the leader of the gangsters, and he is familiar with all the traders on North Street, so he directly found the big merchant Jia who trafficked gray sugar on Chang'an North Street to ask for goods.

Hearing that the green monkey wanted to buy the goods for the same money at one time, the merchant was surprised, this is the time when the sugarcane is on the market, the gray sugar is cheap and terrible, from him the general hawker wholesale is only two pennies a catty, most of them are made into children's food for sale, but the hawker buys dozens of catties at one time, at most hundreds of catties is great, the green monkey buys the consistent money, at least five hundred catties.

This businessman is the most sensitive to business, and he is willing to sell it to the green monkey at the usual price of 600 catties, and the only requirement is to meet the owner of the green monkey. The green monkey remembered Yang Tian's instructions and couldn't let others know the secret of buying these things, but this businessman and the green monkey were acquaintances, knew where the green monkey's house was, and needed his ox cart to deliver the goods, so the green monkey had to agree to bring him over.

Without Yang Tian's permission, the green monkey still didn't dare to take the merchant to see Yang Tian directly, the ox cart arrived at the door, he instructed Yang Shi, Yang Miao and the two of them to accompany the merchant to wait, and he went to report it himself.

Seeing the green monkey coming back empty-handed, Yang Tian asked suspiciously, "Where is the sugar?" ”

The green monkey explained the situation and asked, "Childe, do you want to meet the merchant?" ”

"Did you tell him who I am?"

Qing Monkey hurriedly shook his head: "Without the permission of the child, how dare I make my own decisions." ”

"Alright, send him away."

"Yes." The green monkey no longer asked, and after going out, several people carried the sugar bag into the courtyard, and drove the merchant away, and the merchant had no choice but to leave after wandering outside the courtyard for a while.

Yang Tian opened the sack, stroked the gray sugar sound, put it in his mouth and chewed it, and suddenly a sweet feeling came from his mouth, but then there was an astringent feeling, and there were many rough fibers on his tongue, no wonder such gray sugar could not be sold for money.

Yang Tian lifted the sack and poured it directly into the big water tank in the courtyard, and in the blink of an eye, most of the sack fell, and the green monkey and the others all screamed.

Yang Tian put down the remaining half-sack of sugar cubes, poured the lime water that had been prepared into the water tank, and stirred it vigorously, and the sugar cubes in the water tank began to slowly disappear.

Yang Tian looked at Sun Qing who was stunned by the side, and the green monkey waited for the others: "Twist them well, and then filter them with gauze." ”

Yang Shi, Yang Miao and the others all found it interesting, and each took a big wooden stick and began to twist it vigorously in the water tank, but the green monkey hesitated: "Childe, add lime to the sugar, won't all these sugars be destroyed." Sun Qing also looked at Yang Tian suspiciously, almost the same way.

"You will know after you can't destroy it, Sun Qing, you go and make a fire first, Yang Qinghou, you prepare gauze."

"Yes." Although their questions were not answered, the two men complied.

After filtering the lime sugar water, a lot of the rough fibers in the original gray sugar cubes have been removed, and several people have realized it, but now there is a strong lime smell in these sugar waters, and it is definitely not possible to eat them, everyone looked at Yang Tian, waiting for what to do next.

The charcoal is thriving in the stove, and Yang Tian inserts the conduit made of iron sheet on the stove into the water tank, which is the most expensive thing in the process, and it costs two times just to make this conduit.

Countless bubbles bubble up in the tank, and the carbon dioxide combines with the lime water in the tank to form white calcium carbonate, which sinks to the bottom of the tank.

Everyone present saw this miraculous scene, and as the bubbles bubbled out, the water tank could be seen with the naked eye that there was suddenly a lot of white substance.

"Childe, are you practicing Dan?" In the view of the green monkey, only those immortals and other people can see such a spectacle, in order to avoid taxes, the Great Zhou monk Daonu was at its peak, the country has one-tenth of the people to do monks, Taoist priests and nuns, until Emperor Wu took power, deeply felt the harm brought by the monks to the Great Zhou regime, ordered all monks, Taoists, nuns must all return to the world, Buddhism and Taoism in the Great Zhou only weakened, however, Emperor Wu of Zhou was in power for only five years, although the country banned monks, many people still believe in the flow of immortals.

Yang Tian just shook his head and said nothing, and when there was no more white substance in the water and gradually became clearer, Yang Tiancai stopped inflating and ordered several people to re-filter the water tank and remove those white substances.

After re-filtering, the water tank suddenly turned into clear water, and there was no longer that lime taste, so I dipped it with my hand and put it in my mouth, only to feel a burst of sweetness through the tip of my tongue.

"Come, taste it too."

Everyone put the sugar water into their mouths according to the words, and their faces showed a look of surprise, and the green monkey shouted first: "Childe, we have made a fortune." The others nodded at the same time, and they could get such sweet water, even honey.

"Well, take out the clay pot, fill it and heat it up to evaporate the water."

Everyone took out the clay pot in a hurry and began to heat it, half an hour later, with the evaporation of a large amount of water, the liquid in the clay pot became thicker and thicker, and when it was already extremely thick, Yang Tiancai ordered to stop heating and slowly wait for it to cool.

After finishing all this, it was almost dark, Yang Tian ordered a few people to move all the clay pots back to the room, cover them with lids, and re-emphasize the sense of secrecy before returning to the Guogong Mansion.

Early the next morning, Yang Tian took Sun Qing to the small courtyard of the green monkey, and lifted the lid of the clay pot that had been completely cooled, and there was already red sugar inside.

But before they could sigh, Yang Tian ordered them to pour all the sand sugar into the water tank, pour in clean water, mix well, and put crushed charcoal into the water.

If it weren't for Yang Tian being their master, I am afraid that everyone would have to oppose it desperately, but Yang Tian looked resolute and did not explain, so everyone had to do it.

This time the wait was longer, and after another day, Yang Tiancai asked everyone to filter the sugar water, and then heated, evaporated, and cooled.

On the third day, everyone was stunned when they reopened the clay pot, the clay pot was snow-white, and they put the snow-white sugar into their mouths with their hands, and the sweetness did not decrease, but this appearance was much better than the red sugar.

Yang Tian looked at the stunned crowd and said proudly: "See, this is the real sugar, without any impurities." ”
