The beef jerky was completely dried after four days of drying. This is due to the good weather these days. The sun is not only fierce, but also the sunshine is long. The annoying clouds have never come to cause trouble. In addition, there is always wind in the valley, which is two days shorter than Yun Zheng expected.

The Liang family was still the same as trustworthy, sending some linen, salt, needles and iron pots, but what made Yun Zheng happiest was the ten-pin Jiaozi.

At this time, Jiaozi could only be used in Shu. Shu was a place with less copper. The worst quality of copper coins in the Song Dynasty was Shu. However, the commercial trade here was very developed and a large amount of copper coins were required to be circulated. Therefore, poor money and iron coins were flying all over the sky, and merchants were very annoyed, so Jiaozi came into being. However, this thing can only be used in Shu now. After going to Tokyo Bianliang City, it can be exchanged in shops opened by giant merchants in Shu.

Not only does he save money without interest, but he has to pay a considerable fee. Yun Zheng, who is very unaccustomed to doing this, looked at Liang Qi's pride and had to shut up obediently. As long as it is a merchant that can open Jiaozi, it is definitely a well-known and reputable merchant in Shu. The prefect of Chengdu Zhang Yong only allows sixteen businesses to issue Jiaozi, so Jiaozi is better than copper coins in many cases.

When Yun Zheng saw Jiaozi for the first time, he felt a strong criminal impulse in his heart. Jiaozi's pattern was composed of wooden figures in the house and made of patterned borders. The graphics were complex and it was not easy for counterfeiters to imitate. In addition, "the auxiliary household letters were stamped, each with secret titles, and the ink was first tied in the ink" multi-color overprinting: For safety and anti-counterfeiting, red, blue, black and other colors have been used to cover the pattern patterns and official seals. This is about the beginning of the two-color and multi-color overprinting.

Looking at the rough color pattern on it and the huge Liang sign, and then looking at the secret seal of the Liang family, Yun Zheng wanted to get some paper and print Jiaozi himself. Only fools would use the year, month and day as the secret seal of Jiaozi. Although the year, month and day were changed to the name of "Tai Sui", and then torture, conflict, defeat, and harm, and these fates of Tai Sui were violated to determine the year, month and day, and finally, choosing a person's birth date and eight characters to embed it into it became the secret seal of the Liang family.

Yun Zheng looked at the sun with Jiaozi. The papers were opaque. Liang Qi smiled and said, "This is Jiaozi that my father personally opened. You can exchange it for copper coins or silver when you arrive in Chengdu."

Yun Zheng nodded and put Jiaozi in his arms, looked at Liang Qi and sighed, "I'm too familiar with you, it's hard to start."

With one sentence, Liang Qi's pretty face turned red, and he beat Yun Zheng twice and said, "Bah, who do you think I am!"

"Who cares who you are? I mean your Jiaozi. This is a life-threatening thing for your family. You dare to do such shoddy work? Do you think I can't find a craftsman who carved out the wooden figures? Or do I can't count the number of rafters on it, or do you think I don't know what color printing is? There are sixty Tai Sui, which is indeed a lot, but there is one Tai Sui corresponding to the birth date and month. Even if your family uses the Tai Sui method to get seven more, so what? Just find out who is using this year, and then do a simple math problem and you can solve it, and then you can create the same Jiaozi.

It will take half a month to go from Doushaguan to Chengdu Prefecture, so your family wants to reconcile the accounts, at least half a month later. I strongly suspect that your family is a reconciliation in a quarter, and it takes so long to get away with the last copper coins of your family."

Liang Qi's legs were soft and her butt sat on the ground. She didn't even know about these things. She couldn't see any blood on her face. She only pointed her finger at Yun Zheng and kept saying: "You, you, you..."

He asked the bacon to help Liang Qi up and sit down, poured him a cup of tea before saying, "Depending on how you looked just now, did you even have the intention to silence me if you killed me?

That's right. The fate of your whole family is maintained on this piece of paper. If I were replaced by me, I would kill people, and I would kill them completely. There are more smart people in this world. In the eyes of others, your family's Jiaozi represents a few cents of money, but in the eyes of some good people, it represents endless fun. Through meticulous thinking, decoding, and precise mathematical calculations, it can be solved.

Don’t think that there is no such boring person in the world. There is one person standing in front of you. You are so stupid. You still take all the responsibilities on yourself. Why don’t you pass on this risk to the lord? As long as the person who saves the money is secretly deposited, it is good to do so. Once the person’s money is taken away by someone else with fake lords, the person who saves the money can’t withdraw the lords, and you can’t keep it well.

This idea is worth at least 1,000 yuan, and I don’t want your family’s money either. You just need to go to the furniture store in Doushaguan to buy the most expensive set of furniture. Grandma’s, such a good thing is not something you care about.”

Liang Qi ran away, and the mule cart was urged by her as if it was about to fly. This time she was really scared.

Yun Er stood on the steps and watched Liang Qi fleeing in a panic and said to Yun Da: "Why don't you know how to be more pityful? You just talk nonsense. We have done this before. We wanted to break your bank password. But after experimenting several times, but it was unsuccessful. Your computer password was not broken. This matter is not as easy as you thought. There are sixty Tai Sui. Take it into the equation. Do you plan to solve it with your hands? You can't exhaust you!"

Yun Da rubbed his nose and said to Yun Er angrily: "It is because of you that I have no favoritism for all thirteen or fourteen-year-old children. You are not only in trouble, but also in danger."

Yun Er said quietly: "Even if you want these troubles in the future, no one will bother you."

Yun Zheng felt so sad in one sentence, yes, those children were just a little naughty, but they were actually rare good children, smart, honest, and perhaps a little kind.

Shaking his head and driving these bad feelings out of his head. Today is an important day. Lai Ba is coming to Woniu Shi to receive goods. I heard that this time he organized a total of ten people, each carrying a hundred kilograms of goods to trade with the Tubo people on the other side of the mountain. This was discussed by Lai Ba and Tsashi. When they arrived there, Tubo people would come to greet them.
