I have a supermarket system, shocking the whole court

"The hairpin you like is 40 strings of cash, and after giving a 32% discount, it will only be strings of cash."

"This bracelet costs 60 guan, and after giving a 48% discount, it only costs guan."

"This ring costs 10 guan, and after giving a 8% discount, it only costs guan."

The shopkeeper knew the prices of all the accessories by heart. He counted on his abacus and introduced the items on the plate.

While the shopkeeper was quoting the price, Ning Ning was also converting frantically.

In Daliang's currency exchange rate, one string of money was equal to 1000 copper coins, or one tael of silver.

In terms of currency conversion, 10 taels of silver equals 1 tael of gold, but the jewelry was sold at 20 taels of silver and 1 tael of gold, which is double the price.

From this point of view, it is more cost-effective to exchange it directly for gold ingots.

However, there is another problem. The main currency in Daliang is silver and copper coins. Gold ingots are usually handed in as taxes and salaries, or just collected and played with by nobles. When they are really used, they still have to be exchanged for silver.

However, the biggest problem is not this, but the gold content of gold ingots is only 10%, which makes no sense for Ning Ning to collect them.

On the contrary, jewelry with a gold content of 70% is more cost-effective. Although the price has doubled, the gold content has increased by 7 times.

She had 100 taels of silver. After buying a hairpin, a bracelet and a ring, she had 12 taels of silver left, which was enough for her to get around on the road.

The total weight of the jewelry purchased was 375 grams. After removing 30% of the impurities, the final weight was 262.5 grams, which is equivalent to 5 yuan.

17 yuan came in all at once!

Ning Ning's mind suddenly became clear, and she immediately made the deal with the shopkeeper.

The shopkeeper didn't expect to make such a deal so early in the morning, and he even gave her an extra pair of earrings, but these were not made of gold.

Ning Ning didn't care. It was a free gift, so why not take it?

After completing the transaction, Ning Ning looked at Shang Wenqi in a very good mood: "I'll treat you to a delicious meal."

Shang Wenqi curled the corner of his mouth. Although he was disdainful, he still followed Ning Ning to a noodle stall.

"What do you want so much gold for?"

While waiting for the noodles, Shang Wenqi couldn't help but ask the doubts in his heart.

Ning Ning was stunned and blinked innocently, as if thinking about how to answer.

Shang Wenqi sneered: "You don't want to use this method to pay off your father's 100,000 taels of gold, do you?"

"Look at what you said." Ning Ning shook her head in disapproval: "First of all, my father must have been wronged. Secondly, my jewelry is really a drop in the bucket compared to the 100,000 taels of gold. If I really plan to use this trick, I will never be able to raise it in my lifetime."

"Why is that?" Shang Wenqi was puzzled.

Thinking back carefully, when she saved Si Yang, she was staring at the hairpin on her head. Last night, when she jumped into the water to save someone, she seemed to be attracted by her gold bracelet. Today, she went to buy jewelry early in the morning with the 100 taels of silver reward.

The love of money shown by Ning Ning was the most rare thing in his life.

Even the most corrupt officials in the court are not as addicted as her.

Ning Ning showed the most innocent expression in the world: "I am now a serious criminal in the court, and I have to go to the capital to seek justice for my father. I will definitely have to make all kinds of arrangements along the way, so of course I have to prepare for the rainy day. Will the nobles in the capital be interested in silver and copper coins? I can only exchange for something valuable."

There was nothing wrong with what he said, and Shang Wenqi was speechless.

At this time, their noodles were cooked and the boss served them to them warmly.

"This is the most delicious noodle in our Xingyuan Prefecture. Please have a try, my two nobles."

"You're welcome." Ning Ning thanked him quickly.

They have been eating dry food these days, so after eating this hot bowl of noodles, they feel refreshed all over.

The two had just finished eating and hadn't stood up yet when someone came over.

They subconsciously looked up and saw that it was the prefectural attendant who had sent them back last night.

"Ms. Si Yang, Mr. Chu, good morning. Our master and mistress invite you. Please honor us and move over."

"Why did your master come to us?"

"That... I don't know. You two will know once you come to my house and talk."

The attendant's words were polite, but his attitude was firm.

The two of them didn't hesitate, they got up to pay the bill and followed them.

This time when the two of them arrived at Xingyuan Mansion, they were taken directly to the main hall. Compared with the side hall last night, the treatment was like heaven and earth.

There are soft seats, fragrant tea and pastries here, and all hospitality is carried out according to the standards of VIP guests.

Ning Ning looked around without leaving a trace. After a while, the sound of footsteps and the rustling of clothes were heard outside. Then the prefect and his wife, whom she had met last night, came in.

The two of them saluted respectfully.

The prefect and his wife accepted their greetings and politely asked them to sit down.

"The main reason I invited you two to my house today is to thank you for saving my daughter. I was suddenly unable to thank you last night, so please forgive me for not being able to do so."

"You are too polite, sir. You and your wife gave us a thank-you gift yesterday. To be honest, what you gave us is far more than what we have done. We are already unworthy of it. If you continue to be polite, we really don't know how to respond."

Ning Ning didn't even use her brain, the original owner's genes automatically came up with polite words.

These polite words really made the magistrate and his wife happy.

After a while, the prefect finally got to the point: "I wonder what your plans are for coming to Xingyuan Prefecture?"

"What the prefect means is..."

"To be honest, you two left Kyoto and wandered around just to find a place to stay, right? But to tell you the truth, Xingyuan Prefecture is not where you two belong."

Ning Ning was surprised. Did the prefect mistakenly think that they were going to settle down in Xingyuan Prefecture?

"To put it more simply, there is no place in Daliang that is suitable for you two to settle down. The person who tied the bell should untie it. You should return to Kyoto and solve the root problem."

"You..." Ning Ning was a little surprised. She really didn't expect Xiao Zhizhou to say this to her.

Xiao Zhizhou showed a rare sincerity: "After all, the whole world belongs to the king. This is all I have to say. The rest can only be figured out by the two of you."

The implication was that if they had not saved his daughter by accident, he would not have said anything more.

Ning Ning lowered her eyes and knelt down.

"To be honest with you, Lord Governor, I have been thinking about what to do these days. My husband and I have indeed been freed from the music industry and have become good citizens. However, people's words are scary. Some people don't even look at the evidence, or they think that a small letter of free will becomes a joke in the face of power."

"Miss Si, be careful with your words."

Ning Ning smiled: "Now that the prefect has given me some advice, my husband and I are suddenly enlightened. Since the road ahead is bleak, we might as well return to where we were, solve the problem from the source, and start again."

"It's good that Miss Si thinks this way. My efforts are not in vain. Since Miss Si saved my daughter, I can still give her a favor."
