When Cao Yun arrived in Yuejing, he still came by a carriage, but when he left, the Ming Dynasty's rail car finally built all the way from Zhengyang to Yuejing, which made the Ming Dynasty use rail carriage to completely connect Changyang, Zhengyang, Shayang, Yiyang, Wuling and other places. The way back was Wuyi, and he could take a rail carriage all the way to Wuling. In the past, even a scout rode a fast horse, it took half a month to get there, but now it only takes a few days.

Accompanied by the railcars were stations along the way and camel horses kept next to the stations for replacement. People didn't have to get off the bus, and they could all be solved by eating, drinking, and urinating. Cao Yun knew what this meant.

As long as Qin Feng thought, he could transfer the garrisons spread across these places to the front line as fast as possible in a short period of time, without having to assemble a huge army in a certain place.

For example, when Qi State gathered large-scale troops in Changning County, the logistics pressure was extremely high, and the daily consumption was astronomical. Ten percent of the food and grass transported from various places to Changning County when they set off. After transporting to the local area, half of it would arrive was quite good, because the villagers also had to consume it on the way.

This is basically not a problem for Ming people. The huge and fast transportation capacity of rail cars can quickly transport materials to the front line without any slight consumption.

Sitting in the VIP room of Yuejing City Railway Station, looking through the window at the tracks made of cars parked on the tracks below, Cao Yun's heart was filled with worries.

Unlike the stations he saw in other places, this station in Yuejing City is built quite high-end, atmospheric and upscale. In addition to the ordinary waiting room, there are also VIP rooms specially prepared for VIPs.

An official walked in and whispered a few words in Quan Yun's ear. Quan Yun nodded, walked to Cao Yun's side, and smiled and said, "Your Highness, Your Majesty has a moment to arrive. It's really a coincidence that today, Zhong Zhen, the governor of Yong County, arrived in Yuejing. Your Highness knew that Yong County, as our Ming Dynasty, was in great responsibility on his shoulders. When Your Majesty met Zhong Zhen, he would inevitably exceed the scheduled time. I would forgive my guilt and forgive me!"

Cao Yun shook his head and said, "Your Majesty is taking the time to see Cao Yun off in his busy schedule. Cao Yun is flattered and feels guilty. How dare he still have any complaints?"

"Thank you for your understanding of Your Highness!" Quan Yun said.

"Shoushou Quan, I just saw them hanging a carriage behind them. The things they put into it did not seem to belong to us." Quan Yun pointed below, and station personnel dressed in blue work clothes were throwing bags of things into the carriage, which did not seem to be any valuable thing.

Quan Yun glanced at it and smiled and said, "Oh, this is a letter."

"Letter?" Quan Yun raised his eyebrows.

"Yes, communication between places was quite troublesome in the past, especially ordinary people who wanted to send a letter to relatives and friends in other places, there was basically no other way except for the requestor. However, with the opening of the rail car, this matter was solved. Now, as long as you write the letter and send it to the designated location, special people will sort and pack the letters according to different locations, and then transport them to various places with the rail car. After arriving at the place, the local area will be left.

The people distributed these letters to the letter recipients. Yuejing City is the largest city in the Ming Dynasty, with a large number of foreign populations, so this letter is particularly more. However, the yellow cloth bags you just saw are all letters from the soldiers. His Royal Highness knows that we have many garrisons in Yiyang, Wuling and Taoyuan, and many of them are Yuejing people. The soldiers are always serving away from their relatives and being able to read their family letters is a great comfort for them."

"What a genius idea." Cao Yun exclaimed. "I don't know if that person could come up with such a trick!"

Cao Yun laughed: "It's not actually a trick, it's just another way to make money. It's just a way to make money, but it also makes the people convenient. His Royal Highness, this is not free. Each letter is charged different fees according to the delivery location. In addition to paying the salaries of those distributors, there are also some savings, which can be regarded as making up for the income of the court. Now our Ming Dynasty railcar is a money-losing product."

"Loss money?"

"Of course you lose money." Quan Yun smiled and said, "This track car has huge investment and consumes a lot of operation. For example, Yuejing to Shayang, Zhengyang, or Changyang Baoquan, you can naturally achieve a slight surplus, but you can lose money to Yiyang Wuling and other places. Although you don't make much money to deliver letters, no matter how small the mosquito legs are, it's still meat!"

"I'm afraid this mosquito leg is not small? In addition to adding more people to sort and deliver it, the rail car is basically just on the way, with not much cost, but if there are enough letters, the daily income will be quite considerable. In the past year, I'm afraid it's not a small amount." Cao Yun pondered.

"This business has just started recently, but let's take a look. It's still mainly promoted in the military, making money is still secondary, and it is mainly to alleviate the soldiers' homesickness." Quan Yun said with a smile.

This business, which was called postal service in the Ming Dynasty, is certainly not as simple as Quan Yun said. In fact, this is a business proposed and organized and implemented by Tian Zhen, the deputy commander of the Eagle Nest. The people in charge of this business are also the personnel of the Eagle Nest. The purpose of the Eagle Nest is to build an intelligence network across the country as the postal service is spread across the country. This new business that can greatly facilitate people's livelihood will inevitably be fully deployed in the foreseeable future.

Of course, only a few people know this inside story. Quan Yun has too much power to oppose Eagle Nest from the bottom, but because this business can not only increase fiscal revenue, solve the employment of more people, but it can greatly facilitate people's exchanges with each other, but it can't find too many reasons to oppose it.

But deep down, he thought that in the future, he must convince His Majesty to take this work back from the hands of the Eagle's Nest and set up a separate department.

In Quan Yun's view, since letters can be mailed in this way, then some other things can naturally be mailed in the future. This will be a promising undertaking and can involve all aspects of all walks of life. Of course, now, the layout of Eagle Nest also has its advantages, that is, it will not encounter too much resistance and can quickly arrange each node.

Now he is naturally deeply hiding this little thought in his heart and will not speak to others.

"Sure enough, life is full of knowledge and can be made everywhere!" Cao Yun sighed. "This trip to the Ming Dynasty, Cao opened his eyes and made a great effort."

"It's a pity that the prince saw it, but it doesn't mean that the Majesty of Daqi saw it." Quan Yun said quietly: "The prince is probably full of difficulties in implementing some of the Ming policies in Daqi."

Cao Yun's eyes flashed and he smiled and said, "As long as it is good, it can always be promoted. He does not change it based on the likes and dislikes of some people. For example, this postal service. As long as he knows its benefits, ordinary merchants can also develop it. Our Daqi does not have the track car of the Ming Dynasty, but there are always other ways to replace it."

Quan Yun laughed: "Your Highness the Prince should not underestimate this matter. There are quite a few manpower and material resources required. If it were not for the court, in Daqi, only those wealthy families would have the financial resources and means. Is this another way to make money that Your Highness the Prince found for them?"

Cao Yun closed his mouth and stopped talking. No matter what moment the Chief Cao assisted, he would never forget to sow discord, but he had to admit that what he said was the truth.

Long live a cry came from outside. Cao Yun and Quan Yun turned around and looked at the door at the same time. Emperor Qin Feng of the Ming Dynasty arrived.

The door of the VIP room was pushed open and Qin Feng appeared at the door.

"I've seen Your Majesty." The two bowed to the ground at the same time, but the others in the room all knelt down.

"No need to be too polite, get up." Qin Feng waved his hand and walked to Cao Yun, "You will be late, please don't be surprised by your prince."

"It is Cao Yun's glory to be seen by Your Majesty. How could he say something strange?" Cao Yun bowed and looked at the person behind Qin Feng. Although he was wearing the costume of a civil servant, he had a sharp look on his face. Just looking at wherever he stood, he knew that he was a soldier. He must be Zhong Zhen, the county magistrate of Yong County. This person was a senior general of the Qin Thunder Army, and Cao Yun also heard of it.

Qin Feng was indeed unconventional in his employment. As for Yongdu, the Ming Dynasty controlled most of the central key areas of Qin, he dared to use a person who had fought to the death with him. Not only could Min Ruoying not compare with him, but even Emperor Cao Tiancheng of the Great Qi Dynasty, how could he compare with him? Thinking that the Emperor of the Great Qi Dynasty was increasingly suspicious of him, he couldn't help but feel sad.

"What I regret most most is that I cannot compete with His Highness the Prince on the battlefield. I will never meet again. Qin Feng is reluctant to let go. No matter what, I will come and send you a trip." Qin Feng said loudly.

Cao Yun smiled bitterly. As Qin Feng said, he was afraid that he would not have the chance to command the army in the future. Originally, Emperor Qi was full of suspicion about him and had to retreat. Now this suspicion will only be even worse.

"It is Cao Yun's misfortune to not be able to fight against Your Majesty on the battlefield, but it is also Cao Yun's luck. I have rarely lost battles in my life, but I don't want to lose my moral integrity in my later years and be defeated by Your Majesty on the battlefield."

Qin Feng smiled and shook his head: "If there are people in this world who are concerned about leading troops to fight, His Highness the Prince is ranked first and not facing His Highness the Prince is a pity for me, but for me, the Ming soldiers, it is lucky."
