Li Shimin, who was walking in front, suddenly staggered. He heard everything Su Cheng said just now, and he was stunned.

At that time, he felt that even if Su Cheng had finished laying the rails, he would not make much money by placing the steamed car on the rails. He would have to pay back the money for the year of the monkey and horse month.

Because he thought Su Cheng had only one steam car, but he didn't expect that if Su Cheng laid four rails, it would mean that the round trip would not conflict, which means that the round trip could be departed at the same time.

Moreover, after departure, you can continue to depart again.

Since Su Cheng can build a steam car, it is okay to build another twenty steam cars.

Twenty steamed cars don’t have to be fed, don’t have to rest, and they set off continuously...

How many people travel between Luoyang and Chang'an every day?

Countless!

Are they willing to take a new steam car that can be reached in the daytime or choose to take a horse-drawn carriage, and the ox carriage took several days to arrive in Chang'an?

There is no doubt that I must have chosen to take a steam car!

Therefore, there is no problem with Su Cheng's calculation. Although Su Cheng calculated based on the most perfect situation, the difference will not be very large.

If you recruit people and get goods, you will definitely have one million coins a year!

One million trump card every year, you can make a profit in one or two years, and then you can get one million trump card every year.

One million steadily, one million steadily every year. It was just now in front of him, and it was within reach, but he pushed it out!

Who persuaded him just now!

It's Wei Zheng!

It’s all Wei Zheng’s fault that he missed countless millions of coins!

Not only Li Shimin heard it, but Cheng Yaojin, Changsun Wuji, Fang Xuanling, Wei Zheng and others all heard it, and they were all confused.

They didn't have that many of them before, but now after Su Cheng's careful calculation, they suddenly realized that this was a huge profit!

Cheng Yaojin, Changsun Wuji and others were very jealous. Although the investment was a bit large, it was nothing compared to profit. This is a good industry that could make steady profits and could be passed on stably.

Princess Changle also thought of this. Although there are many industries that make money in her family, who would think there are too many industries? Of course, the more industries, the better. After all, she still wants to have more children for Su Cheng and let Su Cheng grow more.

Princess Changle was very happy, not only because her family could have a strong industry, but also because her father and a group of ministers just now felt that the steamed car made by Su Cheng was flashy.

However, now, the steamed car made by Su Cheng has proved that it is not only magical, but also very practical.

Princess Changle showed a charming smile on her face and asked with a smile: "Father, what's wrong with you? Are you okay?"

Li Shimin just felt weak because of his shock, and immediately stood firm and waved his hand and said, "Of course I'm fine, I just had a bad place."

Princess Changle stepped forward excitedly, held the hand of her mother, and said softly: "Father, you just agreed to issue an order to allow us to lay the railway tracks from Chang'an to Luoyang, so you can't regret it!"

Li Shimin coughed dryly and said, "I'll talk about it later!"

Princess Changle shook her mother's hand and said angrily: "My mother, look, the father has clearly agreed. The father's words can't go back on his word, right?"

After listening to Su Cheng's analysis, Empress Changsun herself was a little dizzy. It was so exciting that even she was very moved, let alone the emperor.

She knew the emperor very well, and she was one million yuan a year, and even the emperor was very jealous.

My daughter is outgoing, Empress Changsun smiled and said, "Your father loves you and Su Cheng the most, will you treat you couple badly?"

Li Shimin walked straight into Liangyi Hall, and Empress Changsun followed Li Shimin into Liangyi Hall without leaving, and a group of important officials followed closely behind.

If they had just regarded steaming cars as a novelty before, now they have realized the importance and strength of steaming cars.

Su Cheng was very calm. After all, the technology of the steam engine is in his hands. Although he briefly introduced the principles of the steam engine to Li Shimin and a group of important officials, it was not so easy to manufacture it.

After all, it has been many years since the steam engine was born to its continuous improvement and development.

Li Shimin sighed: "I heard that Su Cheng built a steamed car, so I was very excited. I didn't expect that the steamed car was more powerful than I imagined! Su Cheng, you know the most about steamed car. You might as well tell me how to use steamed car."

"Emperor Yang of Sui mobilized countless people to build the Grand Canal, why? Because transportation is so important for a country. This Grand Canal is the lifeline of the country!" Su Cheng slowly came to the map.

The Grand Canal connects north and south, and transporting grain and goods is much more convenient than taking land. Although Emperor Yang of Sui built the Grand Canal and suffered countless casualties and injured, Li Shimin and Fang Xuanling all understood how important the Grand Canal was to the court.

"So, we should not limit our attention to Chang'an and Luoyang, but build the railway continuously, and the railway can become the second lifeline of the country!"

As he changed his mind, Su Cheng changed his mind and said: "Compared with the Grand Canal, railways have more benefits. It is very simple to build. Compared to digging a canal, nailing the railway tracks to the ground is too simple, and there is no need to mobilize the people!"

"While steaming cars are faster, and they carry more cargo than riverboats! More importantly, the railway can be built anywhere, centered on Chang'an, south, east, west, and north, all of which can be done!"

"Transport food, supplies, and even troop transport. Steaming cars can travel more than a thousand miles a day and night. What does this mean?"

As Su Cheng kept talking, Li Shimin and the ministers began to breathe rapidly, and their eyes became shiny.

They understand the significance of this very much, which is even greater than that of the Grand Canal.

Steaming cars does not need to rest, they are fast and load more, which is faster and easier than transporting them with horse-drawn carts!

Seeing that Li Shimin and others were so excited that they were about to faint, Su Cheng stopped and gave them some time to calm down, and then continued to talk.

"Of course, it is not something that can be done overnight to pave the railway to the Tang Dynasty states, but you can first choose a few most important lines to start repairing, and then slowly improve it."

"Of course, the most important thing is that the railway is so important, it is best to build it by the court and completely take it into the hands of the court. After the railway is built, you can make money through operation, and then use the money you earn to continue to build the railway. This cycle will not be a heavy burden for the court."
