After Jiang Wan gave the order, he put aside the affairs at hand for the time being.

Although Gangneung City and Gong'an County are only separated by a wall, they are very different.

Public security is a new county of Xuande Gong, the city is small and the walls are short, and it can even be said that it is basically a large military camp at the beginning.

With the continuous changes later, the displaced people were attracted to reclaim the wasteland, and the sloppy military camp gradually became the current small county town.

Sun Qian had planned the city for the public security at that time, but the subsequent development of events was almost beyond everyone's expectations.

A small light curtain unfolds in the air, and through this thing, we know the rise and fall of thousands of years, develop craftsmanship, and correct ourselves.

Nowadays, Jingzhou has Bashu in the north and Hanzhong in the west, and Jiangling's goods are more endless.

Jiang Wan once lamented that Jiangling may be the strongest city in the world, but now he laments that this city seems to be a little small.

This year, the wharf outside Gangneung City has been expanded twice, especially since October, and the number of cargo ships coming and going from Gangneung City has suddenly increased.

Jiang Wan is now in charge of Jingnan affairs, and he naturally knows this:

It was mentioned in the official documents of Yizhou that after obtaining the method of making sugar, Kong Ming promised heavy profits and personally led the gathered people to open up fields for planting sugarcane in Nanguang.

This batch of sugarcane began to be harvested in September, and Chengdu's sugar production has more than tripled.

Chengdu official market began to sell cane sugar in large quantities, which quickly flowed into Jiangling, and was then brought to Jiangdong by Jiangling merchants.

As a result, a large number of merchants moved when they heard the wind, and thousands of merchant ships in Jiangdong went upstream, all eager to get this sweet thing to sell.

There are also countless spies mixed in, wanting to find this method of sucrose.

Jiang Wan sighed:

The victory in the Battle of Jingxiang was not congratulated by Sun Hou in person, but when he heard that there was sucrose, he couldn't wait to spill Sun's secret agent.

Sun Hou, think about it, otherwise you can donate Jiangdong to do business?

However, these merchants stopped when they arrived at Gangneung, not because they were afraid of the turbulent water ahead, but because they saw the notice posted by Jiang Wan in Gangneung City.

It should be said that Mi Zhu and Liu Ba had long expected this situation, so they opened an official market in Jiangling City to sell cane sugar.

It is also because of the opening of this official city that the prosperity of Gangneung City has been raised to a higher level, and the wharf outside the city has more than doubled.

Jiang Wan happened to run into Zhou Qun when he went out, so he simply took Zhou Zhongzhi out for a walk.

Zhou Qun's ancestral home is Langzhong, in addition to being quite accomplished in astronomy, he is also Liu Zhang's nominal teacher, so he seems to be quite a gentleman.

Now Zhou Qun deals with the affairs of Liu Zhang's General Zhenwei Mansion in his spare time, and when he is busy, he will also help Jiang Wan to deal with Jiangling affairs.

As for General Zhenwei's mansion, another person named Changyu is usually very busy, and he has to constantly run inside and outside to contact those miserable surnames who were bullied by Liu Bei's "tyranny", unite in one place, and only bring Prime Minister Cao Cheng's army to recapture the land that belongs to them anyway!

Zhang Yu is happy about these things, and therefore calls himself Liu Zhang's confidant, he is too lazy to pay attention to Zhou Qun, who has no sense of existence, and he will not care about what Zhou Qunping does.

"Gongyan is so Yaxing today?"

Zhou Qun, who was dragged away, was slightly curious.

"It's just a little emotional, and I invite Zhong Zhi to travel with me."

Jiang Wan laughed, slowed down after leaving the mansion, and asked:

"Is the golden ticket on General Zhenwei's mansion enough?"

This golden ticket is a new thing that Liu Ba made.

Now that Yizhou is stable, there is naturally no need for such an urgent strategy as 100 dollars, but referring to the currency, Liu Ba has a new idea.

Nowadays, if merchants want to buy cane sugar in Gangneung, they can only exchange materials for golden tickets, and then use the golden tickets to buy what they need in the official market.

The golden ticket was commissioned by Liu Ba Kong Ming to secretly set up a paper workshop in Chengdu, in which the papermaking method of later generations of Xuan paper was mixed with leather paper, doped with hibiscus petals as the main material, supplemented by several unknown auxiliary materials, and finally made a special paper with a special color, gorgeous appearance, smooth feel and excellent toughness.

After a few months of making this special paper, the secret paper mill secretly removed it again, and handed over the paper-making recipe to Xuan Degong to seal it personally, so as to ensure that no one could imitate the paper for several years.

After cutting it, the book is inked with gold powder, and then stamped with the seal of Xuande Gong, so that it is a golden ticket, and you can buy special products such as sugar, sugar, Shu brocade, and cloth.

The materials collected by the official city of Jiangling City with golden tickets were also all exported to Jingbei.

Liu Zhang, as General Zhenwei, was also given a part of the golden ticket by Liu Bei, which was used as a reward for the previous list, so that Liu Zhang could use it in exchange for sucrose.

Zhou Qun smiled and said:

"No matter how much General Zhenwei squandered sucrose, he was only one person, and the gift from Xuande Gong was completely sufficient."

Jiang Wan nodded, and in his opinion, it should be the same.

After all, the lord is not greedy for Liu Zhang's private treasury, and with his strong financial resources, there is no problem at all to live this life comfortably.

The two walked slowly along the street, looking at the scenery and chatting about some interests outside of official duties, such as arithmetic.

The promotion of arithmetic was not easy, so Kong Ming and Liu Bei chatted and chatted, and finally decided to promote it among the officials first, and not to force it for the time being.

But Jiang Wan has seen the light curtain and knows the importance of arithmetic, Zhou Qun himself has a certain attainment in astronomy, and he has a good foundation in arithmetic, so the two talked very happily for a while.

But soon the two saw someone with better arithmetic skills:

A group of businessmen squatted at the gate of the official market and tried to calculate what kind of materials to exchange for golden tickets.

This requires calculating how much a golden ticket is about, and then taking into account the size of the charter ship and the daily cost of different materials, and then calculating the money paid for the laborers and the price at which the golden ticket can be exchanged for different places.

The two of them looked at it with interest for a while, and then they were driven away by the merchants.

"Arithmetic is really the study of application."

Jiang Wan patted the head of the city wall and sighed.

There was no need for him and Zhou Qun to eavesdrop on the trade secrets of the merchants, and it happened that the official market was near the city gate, so they simply went up to the city wall to walk.

Zhou Qun stood aside, and instead of lamenting how arithmetic was, he brought up another topic

"Gongyan is worried?"

At this time, there were no outsiders on his side, so Jiang Wan said directly:

"There will be another war tomorrow, and Zhongzhi can go back and inform General Zhenwei."

Zhou Qun stretched out his head to look at the bustling Jiangling below, and he couldn't see the precursor of war at all:

"Where?"

Jiang Wan overlooked Gong'an County from afar, just as Jiangling City under his feet has become a strong city in the world, and Gong'an County has also become a skillful county.

Under the pen of Mrs. Huang, the county is full of water-powered eight-ox crossbows along the coast, and all kinds of raw materials are piled up in the east of the county, adjacent to the west workshop of Gong'an County, and the small high chimneys of the blacksmith workshop are closely adjacent.

This is a kind of city scenery that Jiang Wan has never seen before, but he also knows that the masters of the public security county are now staying in Jiangling City, and they generally do not leave the city easily unless necessary.

This order was given by Jiang Wan himself, in order to prevent a sudden sneak attack in Jiangdong, and if he wanted to rejuvenate the city of Gong'an......

"Where?"

Jiang Wan looked in the direction of Jiangxia in the east, and was a little absent-minded for a while:

"Guanzhong, Jingbei, here, Jingnan, the war is going on together."

Zhou Qun returned to General Zhenwei's mansion and, according to Jiang Wan's order, informed Liu Zhang of the news in its entirety.

I thought that General Zhenwei would be shocked, but I didn't expect him to just impatiently reprimand:

"Why did it stop? Don't stop playing music and dancing! ”

So the dance and music in the hall continued as usual, and the trace of murderous aura brought back by the news brought back by Zhou Qun quickly disappeared invisibly.

"This news is of little concern to General Ben."

Liu Zhang shook his head, leaned on the couch, the expression on his face was very calm, he was really enjoying it with his heart:

"Remember to tell Yu Nanhe completely."

"Just say you didn't hear it."

Nanhe is the word of Changyu.

Zhou Qun sighed, only thinking that Changyu should not be idle for the New Year.
