Not long after, Qinghouer came back, followed by a ox cart with more than a dozen large sacks on it. Qinghouer personally carried the car, and there was also a middle-aged merchant in his forties on the car.

Qinghouer is a gangster leader and is familiar with all the businessmen on North Street. He directly found a large merchant who sold gray candy in North Street in Chang'an to ask for goods.

When the merchant heard that Qinghouer wanted to buy goods that were always worth a lot of money at one time, the merchant was very surprised. It was the time when sugarcane was on the market, and gray sugar was so cheap. The ordinary hawkers from him had only two cents per kilogram, and most of them were made into children's food for sale. However, hawkers bought dozens of kilograms at one time, and at most hundreds of kilograms. Qinghouer's money for a lot of money at one time was at least five hundred kilograms.

This merchant is most sensitive to business. He is willing to sell it to Qinghouer for a consistent price of 600 kilograms. His only requirement is to meet Qinghouer's owner. Qinghouer remembered Yang Tian's instructions and could not let others know the secret of buying these things. However, the merchant and Qinghouer were acquaintances. He knew where Qinghouer's home was and needed his ox cart to deliver goods, so Qinghouer had to agree to bring him over.

Without Yang Tian's permission, Qinghou'er still did not dare to take the merchant to see Yang Tian directly. When the ox cart arrived at the door, he ordered Yang Shi and Yang Miao to wait with the merchant, and he would go and report it first.

Seeing Qinghouer coming back empty-handed, Yang Tian asked in confusion: "Where is the candy?"

Qinghouer explained the situation and asked, "Young Master, do you want to meet that businessman?"

"Have you told him my identity?"

Qinghouer quickly shook her head: "Without the young master's permission, how dare I take my own initiative?"

"Okay, send him away."

"Yes." Qing Hou'er stopped asking. After going out, several people carried the candy bag into the yard and drove the merchant away. The merchant had no choice but to linger outside the yard for a while, and had to leave with confusion.

Yang Tian opened the sack, stroked the gray sugar sound, put it in his mouth and chewed it for a while, and a sweet feeling came from his mouth, but then there was a stingy feeling. There was a lot of rough fiber on his tongue. No wonder such gray candy could not be sold for price.

Yang Tian lifted the sack and poured it directly into the large water tank in the yard. In the blink of an eye, most of the sack fell down. Qinghouer and others screamed.

Yang Tian put down the remaining half sack of candy, poured the lime water that had been prepared into the water tank, stirring it hard, and the candy in the water tank began to slowly disappear.

Yang Tian looked at Sun Qing, Qinghouer and others stunned and said, "Whisk them well, and then filter them with gauze."

Yang Shi, Yang Miao and others all found it interesting, and each held a big wooden stick and started to snatch it vigorously in the water tank. Qinghouer hesitated for a moment: "Young master, add lime to the sugar, will all these sugars be destroyed?" Sun Qing also looked at Yang Tian in confusion, almost the same thing.

"You will know whether to destroy it or not, Sun Qing, go and make a fire first, Yang Qinghou, prepare gauze."

"Yes." Although their questions were not answered, the two acted according to the order.

After filtering the lime-containing sugar water, a lot of the rough fibers in the original grey sugar cubes have been removed. Several people felt aware. However, there is a strong lime smell in these sugar waters now, so it is definitely not possible to eat them. Everyone looked at Yang Tian, ​​waiting for what to do below.

The wood charcoal was growing vigorously in the furnace. Yang Tian inserted the iron tube on the furnace into the water tank. This tube was the most expensive thing in the process. It took two cents of money to make this tube just for this tube.

Countless bubbles emerged in the water tank, and carbon dioxide combined with the lime water in the water tank to produce white calcium carbonate and sink to the bottom of the water tank.

Everyone present saw this magical scene. As bubbles emerged, it was possible to see with the naked eye that there were suddenly more white substances in the water tank.

"Young Master, are you practicing elixirs?" In Qinghouer's opinion, only those gods and immortals can see such a strange scene. In order to evade taxes, when the monks and Taoist nuns of the Great Zhou were at their peak, one in ten people in the country became monks, Taoist priests and nuns. It was not until Emperor Wu took power that he deeply felt the harm brought by monks to the Great Zhou regime and ordered all monks, Taoist priests and nuns to return to secular life. The two sects of Buddhism and Taoism were weakened in the Great Zhou. However, Emperor Wu of Zhou had only been in power for five years. Although he was forbidden to become a monk in the whole country, many people still believed in the gods and immortals.

Yang Tian just shook his head and said nothing. When the water no longer produces white substances and gradually becomes clear, Yang Tian stopped inflating and ordered several people to filter the water tank again and remove the white substances.

After re-filtering, the water tank suddenly turned into clean water, and there was no more lime smell. I dipped it with my hands and put it in my mouth, and I felt a sweet smell that penetrated my tongue.

"Come on, you can taste it too."

Everyone put the sugar water into their mouths as they said, and their faces showed a sound of surprise. Qinghouer shouted first: "Young master, we are rich." The others also nodded at the same time. They could get such sweet water, even honey.

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

Everyone took out the pottery jar excitedly and started heating it. After half an hour, as the water evaporated a lot, the liquid in the pot became thicker and thicker. When it was already extremely thick, Yang Tian ordered to stop heating and wait for it to cool down slowly.

After finishing all this, it was almost dark. Yang Tian ordered several people to move all the pots back to the room, cover them with a lid, and re-emphasized the confidentiality awareness before returning to the Duke's Mansion.

Early the next morning, Yang Tian took Sun Qing to Qinghou'er's courtyard and lifted the lid of the completely cooled pot. It was already red sand candy inside. Yang Tian took out a little and let everyone taste it again. The taste was a hundred times better than the original candy cubes.

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

If Yang Tian hadn't been their master, I'm afraid everyone would have to fight to the death. However, Yang Tian looked firm and did not explain, so everyone had to do it.

This time I waited longer. After another day, Yang Tiancai asked everyone to filter the sugar water, then heat, evaporate and cool again.

On the third day, everyone was shocked when they opened the pot again. The pot was snow-white. They put the snow-white candy into their mouths with their hands, and the sweetness was not diminished, but this look was much better than the red sand sugar.
