In Lin Chuan's view, in order to increase the output of Yizhou's production base, it is not only necessary to build more post stations, but also to expand existing post stations.

Because the transportation function of the post station is only incidental, in order to improve the transportation capacity of the Yizhou post station, it is necessary to strengthen the transportation capacity of the post station.

And to strengthen the transportation capacity of the post station, there are no more than two points.

One was to add more horses and wagons to the station, and the other was to increase the importance of transportation in the station.

What the horses Xianbei people have, especially the horses that are not as good as war horses, are best used to pull carts.

Lin Chuan sent a letter to the shopkeeper Zhao of the Youzhou branch the next day, asking him to mobilize a group of horses in Youzhou and send them to Yizhou.

At the same time, Lin Chuan also sent a letter to Cheng Yu in Youzhou, the head of the town, explaining the situation of calling the horses.

Then Lin Chuan began to think about how to explain to Cao Cao the importance of building and expanding the post station.

After careful consideration, Lin Chuan decided to start with the function of the post station and the importance of the production base.

After making up his mind, Lin Chuan began to write letters to Cao Cao, explaining the importance of the new post station and the expansion of the existing post station in Yizhou.

There is also the need for the cooperation of Xiahoudun, the current head of Yizhou, to allocate a group of manpower for the newly built post station.

Lin Chuan and Xiahoudun got along well, so he didn't worry about the manpower problem of the post station.

After Cao Cao agreed to Yizhou to build a new post station and expand the existing post station, it was not too late to talk to Xiahou Dian.

After Lin Chuan finished writing the letter in the study of the Hou Mansion, he called a guard and sent him to Yecheng to deliver the letter.

After receiving the letter, the guards did not dare to slack off, and set off to Yecheng to deliver the letter on the same day.

Five days later, Yecheng Wei Palace.

Cao Cao was discussing with Jia Xu the letter sent by Yu from Youzhou.

What Cheng Yu said in his letter is the matter of Xianbei and Dawei mutual markets.

Xianbei Kebi Nengbu and Budu Root and Dawei have been trading with each other for two years.

In these two years, both the Kobi Neng Department and the Gado Root have gained great benefits.

First of all, the subordinates under their command can eat the grain traded from the Great Wei Market.

Foods such as potatoes, sweet potatoes and corn that are easy to preserve and make you feel full are very popular with Xianbei people.

One of Kebineng's favorite dishes now is potato stew.

Since the opening of the mutual market, there have been some changes, that is, commodities other than salt, iron and grain do not need to be settled with war horses. Especially after the mass popularization of cotton and cotton cloth, cotton clothes and quilts can also be exchanged for fur cattle and sheep.

The Xianbei tribesmen traded a lot of good things in the Great Wei Mutual Market with cattle, sheep, furs, and various herbs, and the quality of life was greatly improved.

The current Xianbei tribes not only have cotton clothes to wear, but some tribal leaders also use glass cups.

It is the first time for these Xianbei people to live such a happy life, and now they are fully supporting Xianbei and Dawei Hushi.

Great Wei also obtained a large number of war horses from Xianbei, and the Youzhou Iron Cavalry has expanded by 10,000 people in the past two years, and Cheng Yu is also very happy to maintain the mutual market between Great Wei and Xianbei.

This time, Cheng Yu sent a letter to Cao Cao, hoping that the Hanzhong Chamber of Commerce could provide more goods for Youzhou, so that he could trade more fur medicinal materials with Xianbei, as well as iron farm tools produced by the Hanzhong Chamber of Commerce.

After Cao Cao and Jia Xu read Cheng Yu's letter, they were also surprised by the speed of development of the mutual market.

"Lord Wei Wang, this Xianbei man has exchanged 10,000 war horses with Great Wei in the mutual market in just two years, which is really unexpected!"

Jia Xu said in surprise to Cao Cao.

10,000 war horses is indeed not a small number for the Xianbei people, you must know that the training of war horses and the horses are very different.

War horses not only have to go through long-term training, to ensure the combat ability of war horses, but also to feed the war horses, and need special personnel to take care of them.

Now all the Xianbei tribes add up, there are about 800,000 people, and these 10,000 war horses may be the limit that can be taken out in two years without seriously affecting Xianbei's strength.

Cao Cao saw that the Xianbei people traded 10,000 war horses through the mutual market in two years, which was also beyond his expectations.

However, Cao Cao was not very surprised, he smiled and said to Jia Xu:

"Wen He can know that my Great Wei now has 1.7 million households and a population of 10 million, and the Xianbei tribes together are only 10% of the population of Great Wei!"

"They just have 100,000 more war horses, how can they help me Dawei? It's better to exchange the war horse for some salt, iron, and grain! ”

When Jia Xu heard Cao Cao's domineering words, he couldn't help but laugh and said:

"What Lord Wei said is extremely true! Xianbei can continue to exist, but it's just because my Great Wei is developing rapidly, and I can't care about killing them, hahaha! ”

Cao Cao and Jia Xu looked at each other and laughed, both unhappy in their hearts.

Next, Cao Cao said to Jia Xu:

"Wenhe, Zhongde wrote to say that he wanted the Hanzhong Chamber of Commerce to increase commodity production, and it seems that he has to talk to Mr. Lin about this matter."

"Lord Wei Wang, as far as I know, in the past two years, the Hanzhong Chamber of Commerce in various parts of Great Wei has developed rapidly, and a lot of production bases have been built, but I didn't expect that this product is still not enough!"

Jia Xu said with emotion.

Cao Cao thought for a while, and felt that it might be that the Xianbei tribes were already inseparable from the mutual market, let alone the goods of the Hanzhong Chamber of Commerce.

Then Cao Cao wanted to send a letter to Lin Chuan, telling him to mobilize more goods from the Youzhou branch.

didn't wait for Cao Cao's letter to be sent, Lin Chuan's letter arrived first.

Cao Cao and Jia Xu felt that Lin Chuan might have the ability to predict the future, after all, Lin Chuan was still a disciple of the Immortal Family.

After the two read Lin Chuan's letter together, they couldn't help but laugh at the same time.

"Mr. Lin really has the ability to predict the future, this king and Wenhe just mentioned today that the goods of the Hanzhong Chamber of Commerce are in short supply, but I didn't expect Mr. Lin to write to say the solution!"

"The Marquis of Hanzhong is worthy of being a disciple of the Immortal Family, and he directly solved this problem for Lord Wei, hahaha!"

Cao Cao and Jia Xu both said very happily.

Then the two carefully studied Lin Chuan's letter, and agreed with Lin Chuan's proposal to add and expand the post station.

So Cao Cao went on to reply to Lin Chuan, and the letter also mentioned what Cheng Yu said about mobilizing goods from the Youzhou branch.

After replying to the letter, Cao Cao and Jia Xu were in a good mood today, and they had a few drinks together in the evening.

At the same time, the shopkeeper Zhao of the Youzhou branch received a letter from Lin Chuan.

After reading the letter, Shopkeeper Zhao went directly to Cheng's Mansion to visit Cheng Yu.

"Shopkeeper Zhao, let this matter go, the Marquis of Hanzhong has already greeted me."

Cheng Yu knew that Shopkeeper Zhao came to the door for the sake of horses, and said directly to Shopkeeper Zhao.

So after the shopkeeper Zhao left the Cheng Mansion, he immediately began to raise horses.

Linchuan, who was far away in Hanzhong, also began to mobilize materials such as cement and red bricks from the production base in Hanzhong to prepare for the construction and expansion of the post station.
