Yue Ye and Gui Zhiguang each put Xia Yu on one leg and lifted him high.

Zhang Tieniu followed them, with a snare drum tied to his waist.

Parading in front of the sergeants of the Right Army, at this moment, Xia Yu is the hero in their minds.

What Li Yuanba can do, Xia Yu has also done, which means that there is one more fierce general in the right army.

When Xia Yu went back, it was already twilight, Su Lang took Xia Yu's hand and entered the house, and asked mysteriously: "Xia Yu, how much do you guess our toilet is sold?" He held out a finger.

Xia Yu guessed: "One hundred taels? ”

Su Lang shook his head.

Xia Yu: "One thousand taels? ”

Su Lang shook his head again: "Ten thousand taels!" ”

Xia Yu exhaled a cool breath.

Su Lang said with a smile: "Even I didn't expect that there were so many people purchasing toilets in Jinyang City, and the cost of the toilet was only one tael, I found someone to put all kinds of ornaments on it, and each ornament was different, and those rich and noble families flocked to come, selling each for a hundred taels." ”

Even Xia Yu didn't expect Su Lang to be so flexible in business, and it took effort and manpower to decorate the decoration on the toilet, and the calculated ingredients were only ten taels.

Xia Yu thought for a while and said, "Uncle, your current consumer group is concentrated in the rich, and the consumer group is a little thin. If you can sell a toilet to the poor, even if a toilet bowl earns them a tael or two, it's good. Do the math, if 10,000 poor people buy toilets, doesn't that mean that we also earn enough 10,000 taels? ”

Standing up, Su Lang paced around the room, his eyes lit up, and affirmed: "Xia Yu, your idea is really good, why didn't I think of it?" ”

In modern times, this is just a business model called "small profits but quick turnover", but the ancient people did not have such an advanced business concept.

Xia Yu smiled slightly, sat down and drank tea with Su Lang.

Su Lang asked Su Yuexin's attitude towards Xia Yu, and Xia Yu was noncommittal.

Su Lang sighed with emotion: "Yuexin was grown up by watching me when I was a child, my eldest brother is like a father, except for her temper. Who is good to her and who is not good to her, she knows in her heart. ”

"How can I tell you, you have to be more patient with this girl." Su Lang concluded.

Xia Yu nodded in agreement.

"By the way, tomorrow I'm going to Chang'an to do business. Uncle Li also wanted me to go to Chang'an, on the one hand, the wealthy families gathered there, and on the other hand, the news from Chang'an City could be fed back to them. Su Lang's tone was tinged with sadness and tiredness.

It's good to do business anywhere, but it's like a bird floating around, and you can't take care of your home.

It is no wonder that for the ancient people who liked stability, merchants were the lowest status, and even the girl's family was reluctant to marry a merchant.

Xia Yu suddenly remembered that he fell asleep on the washboard yesterday, and the mobile phone reader was running automatically, so he took it out in the morning and took a look at it, and extracted a heavenly lock.

The so-called heavenly machine lock is actually a yin and yang seal. The yin and yang seal is stamped on the paper, which is clearly a seal, and another seal will appear after it is stained with water.

Xia Yu vomited in his heart that this thing was useless, and at this moment he was chatting with Su Lang, and suddenly thought of one thing, that is, during the period of the late Sui and early Tang Dynasty, there was no paper money at all, and there was no money bank.

So he took out the Tianji lock from his arms and said to Su Lang: "Uncle, I will give you a profitable business." ”

He asked Su Lang to take a piece of paper and put a seal on it with a heavenly lock, and Su Lang looked at the seal on it inexplicably.

Xia Yu took out another cup of water and dripped it on the seal, only to see that the original seal disappeared, revealing a new seal.

Su Lang was amazed.

Xia Yu asked, "Our Su family has shops all over the country, right?" ”

Su Lang nodded and said, "Except for some extremely remote markets, there are no shops, and they are basically all covered. ”

Until now, he was still confused, unable to connect the business store with the heavenly lock.

Xia Yu reminded Su Lang: "Uncle, now every merchant who travels abroad must be carrying a lot of property, if they encounter robbers on the road, then they can only hand over all the property, and everything will be in vain." What's more, their lives are very likely to be in danger because of their belongings. ”

When he was about to say more, Su Lang suddenly came to his senses: "You mean, we can use the thing with your strange seal as a credential. Merchants on the trade route only need to take this voucher and go to our Su family's shop to ask for an equivalent amount of property, and that's fine. That's a really good idea. ”

"Yes, we can also keep the merchant's property in our Su family's shop and charge a certain amount of interest every day. In this way, the circulation of gold, silver and jewelry is very convenient, and we can also earn more money with their money. ”

The brain replenishes the real money and silver circulating in the various shops of the Su family, Su Lang's brain is full of gold and silver property, Xia Yu gave him a great business opportunity, there is no one before, and there is no one after him.

Not only that, Su Lang added: "If the wealth in a certain shop is too full, we can also lend the money to some merchants who have no money to do business, so that we can avoid the covetousness of some snitches, and we can make another profit from it." ”

Talking to smart people, sure enough, there is no need to waste too many twists and turns, Xia Yu thought about it carefully, and was shocked in his heart, isn't this the prototype of the bank.

Su Lang took out a pen and paper and recorded all the words Xia Yu just said, what they said was just the initial idea, and if they wanted to put it into action, they had to be filled with all kinds of details. He thought about it carefully, and completely forgot that there was a Xia Yu in the room.

The door was pushed open, and Su Xun was about to come in with a wine in his hand.

Xia Yu gave Su Xun a gesture and signaled not to disturb Su Lang.

Gently closing the door for Su Lang, Su Xun was wearing a suit of armor and took Xia Yu's hand: "I'm looking for you, but I can count on finding you." My good brother-in-law, did you tell Li Laosan what you promised me? ”

Xia Yu said: "I said it." Didn't you go to the army to report? ”

"Hey, I don't have something to do in the past two days, so I'm delayed. When you go to the barracks tomorrow, remember to call me. ”

"Okay, no problem."

Xia Yu was about to leave, but Su Xun grabbed him: "You are in such a hurry to leave, why don't you accompany me to drink two glasses?" ”

As soon as he mentioned drinking, Xia Yu was cowardly, he drank more yesterday, who knew that there would suddenly be a woman's handkerchief in his pocket, causing him to kneel on the washboard for a night.

Thinking of Su Yuexin's angry look, Xia Yufei also ran away: "Yuexin is still waiting for me to go home, and I won't drink with you second uncle." ”

"If you just don't drink, then don't you sleep underground?"
