Spoiling my mistress and swallowing my dowry? After my rebirth, I changed my marriage to a powerful

Gu Shaoyu only saw the people running towards a grocery store, and he suddenly became interested and followed them.

On Dongcheng Commercial Street, there is an old grocery store with only one storefront.

There was a dazzling array of goods inside, and on the opposite side, in the open space where the carriages were originally parked, there was a pile of saltpeter.

The price of saltpeter was originally 5 taels of silver for 100 jin, but a servant stood at the door and shouted, "Saltpeter, 100 jin 25 taels of silver."

The price has increased fivefold.

The strange thing is that the price of saltpeter has increased fivefold and everyone is scrambling to grab it!

All customers did not pay for the goods at the door, but entered the shop, handed in the money in exchange for a delivery ticket, and then picked up the goods at the roadside.

It is obvious that the goods were brought in temporarily and have not been put into the warehouse. They can be picked up directly from the roadside.

With this business, even the storage fees are saved.

Gu Shaoyu and Nanxing watched from the side. Everyone took their carts and sold out all the saltpeter piled in the empty lot in half a day.

Many people crowded over to the shop and asked, "Do you have any more coupons? Please sell us some more."

The other party said impatiently: "There is no more today. We will open at 9:00 am tomorrow morning and more will be shipped in. Everyone wait."

Even the genius Lord Gu couldn't understand it.

In addition to the usual medicinal uses of saltpeter, he also remembered that Tu Qianyue used it to make ice. Could it have other uses?

He saw a young man buying a whole cart of saltpeter, looking as happy as if he had grabbed a gold nugget, and asked politely, "Young man, what are you buying saltpeter for?"

The young man looked at him and said with a smile: "Of course it works!"

What is the use?

People don't say.

He said to Nanxing, "Come over tomorrow at 9:00 p.m. and buy 100 kilograms to see what they are doing."

As soon as they left, the grocery store started selling tickets again, saying that the owner had obtained a new batch of goods.

"We'll only have one batch today, and we won't sell them anymore once they're sold out."

25 taels of silver for 100 jin, grab it!

The next day, Gu Shaoyu went to court early in the morning. His Majesty had not yet arrived, and everyone was whispering in the waiting area.

Gu Shaoyu went over and listened, and heard the words "saltpeter" and "ice making".

"What are you talking about?" he asked gently.

When everyone saw that it was him, they all smiled and said, "There are a few grocery stores selling saltpeter on consignment, starting at 100 kilograms. Anyone who buys more than 200 kilograms will receive a secret recipe for making ice."

"My wife asked the housekeeper to buy several hundred kilograms of ice yesterday. She got the recipe for making ice and made it last night. It froze in the middle of the night and it was very cool."

"Yes, yes, I also bought several hundred kilograms in my house."

……

Gu Shaoyu then understood why those people had to go in to pay and get a delivery ticket. He originally thought it was for ease of management, but it turned out that there was a secret operation to give away secret recipes.

No wonder when he asked the young man yesterday, he was unwilling to tell him.

After some calculation in his mind, he realized that there might not be so much saltpeter in the entire capital city.

"Do you know where the saltpeter came from?"

"It seems that the merchant caravan of Prince Jing brought it from Tibet."

"This time, the prince's fleet brought a shipload of saltpeter. I heard that it was fully booked as soon as it landed."

Saltpeter came from Tubo, the recipe also came from Tubo, and there was also a formal way to get them in.

Everything works seamlessly.

Nanxing, who was asked to buy 100 kilograms of saltpeter, was now squeezing in the grocery store to buy a ticket.

When paying, the recipient said, "Hey, buy 200 kilograms. If you buy 200 kilograms, you will get the secret recipe for making ice for free. If you buy more, you will also get the recipe for making ice products for free."

Nan Xing hesitated for a moment, and the people next to him immediately pushed him aside: "I'll do it."

The man paid 100 taels of silver, took 4 small cards, a secret recipe, and 400 kilograms of saltpeter, and left happily.

Soon the word came out from the shop: "Don't queue up any longer, the saltpeter has all been sold out."

Nanxing quickly bought the last 200 kilograms and also got a secret recipe. When he came out of the store, he saw a luxurious carriage in the distance and four majestic guards.

Xie Zhaozhao's servants Moyan and Guanyan also came in to buy.

"Moyan, the saltpeter in it is sold out." Nanxing kindly reminded.

Mo Yan said happily, "I paid the deposit a long time ago. They delivered the goods to your house. I am here to settle the balance."

Xie Zhaozhao did not get out of the car. He spoke a few words to Nanxing through the curtain and then returned home with the servants.

What Nanxing didn't know was that Mo Yan and Guan Yan went in, one to settle the accounts and the other to block the crowded crowd behind.

What he handed over were silver bills, and what he got back... were more silver bills!

Gu Shaoyu returned home after court and looked at the saltpeter and ice-making recipe that Nanxing had bought. The words on the recipe were engraved from a template and were a little blurry.

No matter how smart he is, he can't find out whose handwriting it is.

He asked Nanxing to do an experiment in a wooden barrel. The recipe was real and could really make ice.

After a night of hard ice, he felt the hardened ice and realized that Gu Chengyan and Tu Qianyue's plan to turn their fortunes around by making ice had been completely shattered.

In the whole city, there are less than ten thousand families who know how to make ice, but there are definitely hundreds of them, including some wealthy families.

For example, the Xie family has mastered the secret recipe for making ice. They have plenty of money and shops. Even ten thousand Gu Chengyans and Tu Qianyues cannot compete with them.

Soon, vendors selling ice products appeared on the street, and those exquisite smoothies and popsicles sold like hot cakes.

It is said that the families in the capital who got the secret recipe went everywhere to look for saltpeter. All the saltpeter within a 500-mile radius of the capital was collected. Even if the price was five or ten times higher, they would still buy it.

It was two or three months later that the transport ships of Prince Jing's Palace urgently went to Tubo and other countries to import saltpeter. By that time, the weather had already turned cold, and those who had saltpeter on hand had made a fortune.

On the day when the saltpeter was sold out, Yuanyuan's cousin sent several cartloads of saltpeter to the Xie Mansion.

At the same time, he gave a box to Xie Zhaozhao.

That was the money from selling saltpeter, a total of more than 62,000 taels. After deducting the cost, the net profit was more than 50,000 taels.

Xie Zhaozhao took out five thousand taels and gave them to Dongqin, asking him to give rewards and gifts to all those who had helped him.

If there is no benefit, who will work for you?

Dong Qin resolutely refused to accept it, saying: "These are all the young lady's ideas. I am just an errand boy and have not done much. What the young lady has given us is already rich and prosperous, which we cannot earn in several lifetimes."

Xie Zhaozhao insisted on giving it to him, saying, "Dongqin, you should buy the three shops under the overpass and put them under your own name. They are prosperous shops, so you can rent them out or pass them on to your children and grandchildren. In addition, you should temporarily leave Kyoto and go to Baiyue."

Dong Qin was stunned: "Miss, are you asking me to leave the capital forever?"

After all, he had offended Lord Gu and the Crown Prince, so there was no guarantee that they would not investigate him.

"No, I have big plans for Baiyue." Xie Zhaozhao said with a smile, "Dongqin, don't you want to go back to your hometown to seek revenge?"

Dong Qin was stunned for a moment when he heard this, then he knelt down and said, "Thank you, Miss."
