"What is this?" Cao Ding looked dizzy.

"crystal sugar."

"crystal sugar?"

Xiao Zhang hummed.

During the three days he was in the palace, he used the sucrose at home through heating and refining methods, and finally extracted these rock sugars.

The main reason is that the technology of this era is too backward, otherwise, it would be more refined and whiter.

"I'm going to sell these as seasonings. Let's see how much this stuff is worth."

Cao Ding hissed, took a piece of rock candy and put it into his mouth.

"Oh, so sweet."

As soon as he took the rock candy into his mouth, Cao Ding was so shocked that his eyes widened.

"Idiot, where did you get this stuff? It tastes much better than caramel."

Xiao Zhang chuckled: "Of course I made it myself. Just tell me, can this thing be sold for money?"

"Yes, I can't guarantee anything else. The princes and nobles in the capital have a lot of money. Even if you sell this small bag for a hundred taels of silver, someone will want it."

Xiao Zhang was stunned for a moment: "One hundred taels of silver? Isn't it too high?"

Grandma's, one hundred taels. This is ancient times. Needless to say, the purchasing power of ancient times. This pack of rock sugar only costs seven or eight yuan. Even including the raw material sucrose, the cost of this thing is no more than three coins.

This has doubled hundreds of times. I am not dreaming.

"I don't study well, so don't lie to me."

"Why did I lie to you? How much do you still have?"

"There are still four or five packets at home."

"If you take it with you when you go to the Guozi School tomorrow, I can sell them all to you on the spot. Believe it or not?"

Xiao Zhang felt a little itchy: "Forget tomorrow, just go home with me now. I'll leave it all to you."

"No, I'm not full yet."

Xiao Zhang didn't care about this. He pulled Cao Ding and stood up: "Eat whatever you want. This stuff is just like pig food. Come on, follow me home and I'll make something delicious for you."

"You can throw it away, what you make is worse than pig food."

The two bickered and went out. Before leaving, Xiao Zhang did not forget to take away the money on the table.

All the way to the palace, when they saw Xiao Zhang coming back, the servants quickly caught him.

"Your Majesty, you are back."

"Well, is the old man at home?"

"My lord, he has gone out to do some business."

Xiao Zhang breathed a sigh of relief, as long as he was not at home.

Otherwise, if the old man finds out about what he learned in Guozi today, he will have to whip himself.

"Follow me."

Xiao Zhang said this and led Cao Ding all the way to his bedroom.

"Idiot, your teacup is quite unique."

When Cao Ding saw the water cup Xiao Zhang used to make a beaker on the table, he immediately started making fun of it.

Xiao Zhang was not in the mood to argue with Cao Ding at the moment, but went to dig out the packets of rock candy under the pillow and handed them to Cao Ding.

"Well, they're all here."

Cao Ding picked one up and looked at it through the window, as if appreciating a gem.

"How much do these cost?"

"It should be about a thousand taels."

"If it sells, I'll give you half of it."

Cao Ding immediately returned the rock candy to Xiao Zhang: "Then I won't sell it."

Xiao Zhang was anxious: "Why did you change your mind? Are you too young?"

Cao Ding looked at Xiao Zhang angrily: "Idiot, am I, Cao Ding, this kind of person in your heart? If I were greedy for money, I would tell you that these things are worthless and then sell them on my own. Then they all belong to me.

In his pocket."

"Well, what did you just say..."

Cao Ding sighed and patted Xiao Zhang's shoulder with his hand: "You idiot, you are different from me. In addition to the monthly money my father gives me every month, my elder brother also gives me some occasionally. It's not easy for you to do this.

If you order something good, how can I share your money again?"

Xiao Zhang was moved by Cao Ding's words.

This is a good person.

One thousand taels was not a small amount in ancient times. It was enough for an ordinary family to last for thirty to fifty years.

Even if they split it half and half, it would still be a lot. Cao Ding actually refused to take such a large sum of money even if he said he didn't want it. This friendship is closer than that of real brothers.

Thinking of this, Xiao Zhang couldn't help but feel a little moved in his heart.

After a brief moment of emotion, Xiao Zhang returned to normal and looked at Cao Ding with a serious expression: "Okay, if that's the case, then I won't give it to you. The brothers said this a little bit. Well, let's wait until I start this business.

How about your 30% share?"

Cao Ding was a little embarrassed: "This is not good."

"That's it. If they are brothers, don't say anything else. Otherwise, I will find someone else to help me sell it."

"No, no, no, it's just me, it's just me."

When he said these words, Cao Ding sighed inwardly.

I don't know where these rock candy idiots bought good things from, but they don't have many if you think about it.

If such a treasure is asked to be helped by others, there is no guarantee that they will have any ulterior motives to deceive him.

As a brother, if I don't stand up at this time, who else can help the idiot?

With this in mind, Cao Ding agreed.

"Brother, in the near future, when the two of us are mentioned in Beijing, four words will come to mind."

Cao Ding asked weakly: "Is there no learning and no skills?"

"Go away, you are as rich as a country."

After saying that, Xiao Zhang picked up a piece of rock candy, his face was all wet.

…

After staying at the Xiangdong Palace for a while, Cao Ding left with Bingtang. Before leaving, he left a bold statement that he would return with a thousand taels of silver tomorrow morning.

After Cao Ding left, Xiao Zhang sat in his bedroom and laughed innocently.

He seemed to have seen the scene of Yinzi waving to him.

At any time, money is the most important thing.

Many of his current ideas to change the world are due to lack of money to put them into action.

"In addition to rock sugar, you can also try to make other condiments. Well, you can also try to make wine, which can be a huge profit. Since you want to transform, let's start with food and drink. Otherwise, there is no motivation."

While muttering something in his mouth, Xiao Zhang found a piece of silk, wrote and drew on it, and listed various chemical formulas.

In the hall of the palace, King Xiangdong returned home with a tired look on his face.

Butler Hu San immediately poured a cup of strong tea.

"Has that idiot come back?"

"Go back to me, Sir, His Royal Highness has been back for more than two hours."

"Go and call him."

"Master, what happened?"

It's okay if I don't ask. But when I asked, King Xiangdong became very angry.

"His Majesty just summoned me to the palace, why do you think it was? This little bastard beat Lu Boming in the Chinese Academy of Sciences. I'm so angry. I can't get rid of my anger without beating him. Go and call him over.

.”

When the housekeeper heard this, he trembled and thought, "His Royal Highness is in trouble again."

He promised with his mouth, but he hesitated with his feet.

Xiao Zhang usually doesn't have any airs about servants like them, and everyone in his family also likes Xiao Zhang.

Now that Xiao Zhang is going to be beaten, will the housekeeper be happy?

While the housekeeper hesitated, King Xiangdong stood up impatiently: "Forget it, I'll go by myself. I can't wait any longer."

As he spoke, King Xiangdong walked towards Xiao Zhang's bedroom in the backyard, pulling out his belt as he went.

Seeing this, the housekeeper let out an ouch, stamped his feet, and hurriedly chased after him.
