Chen Zhengtai smiled and said, "Your Majesty, there are six cars hanging in this car, and this car carries 70,000 kilograms of goods."

Seventy thousand...

Li Shimin was shocked.

Every pound of the Tang Dynasty was about 600 grams.

This 70,000 kilograms is equivalent to forty tons.

Forty tons, which seems not much in later generations, is just a cargo that a heavy truck can carry. But in this era, it is an unimaginable existence.

If a person needs to consume one kilogram of food a day, such a truck of goods can provide 70,000 people and horses with the Tang Dynasty with full in one day.

The load capacity of ordinary carriages is relatively pitiful. For example, the load capacity of the carriage in the Ming Dynasty was about 200 kilograms. In the Tang Dynasty, although four-wheeled carriages appeared, the load capacity could increase by 400 kilograms. Because of the repair of wooden rails, the carriage was lighter, and the carriage volume could reach six or seven hundred kilograms.

Then... the load capacity of this train is equivalent to one hundred horse-drawn carriages.

Of course... Since it is a load-carrying train, of course I don't expect it to be fast. In fact, its speed is similar to the speed of a horse-drawn carriage running wildly on wooden tracks.

But for Chen Zhengtai, the more powerful thing here is not just that!

So Chen Zhengtai said: "This 70,000 kilograms of goods... is worth the load-bearing of a hundred carriages, but a hundred carriages require at least one hundred coaches, and this steam train only requires only five people to make it run. In addition, the horse needs to rest for an hour or two, and also needs to feed the forage. When the groom is tired, he needs to rest and sleep. However, this steam train only needs to add coal and water in the middle, and can run continuously. Now the speed is fifty every hour.

It seems that there are not many, but if it continues to run, it can travel 600 miles in one day, and it only takes more than two days to reach Shuofang. Even if it goes to Xining, if the railway line is built, it will be within four or five days. In the future, it will be directly built from Chang'an to Xining. This time can be shortened to three days. Within three days, starting from Erpigou, 70,000 kilograms of people and goods can be transported to Shuofang and Xining. Your Majesty... This... is the greatest effect of this car."

Li Shimin was completely shocked at this time.

Seventy thousand pounds...

Three days, you can walk two thousand miles!

What if there were ten such cars, what if there were hundreds?

So... this is so convenient than horses. Because both people and horses need to rest, both people and horses have physical limitations. Not to mention, the load capacity of people and horses is very limited.

"Your Majesty... Think about it, my Guanzhong goods can be delivered to Xining, the farthest one at any time. After packing and departing, the treasures of Xining can be delivered to Guanzhong within five days, not only goods, but also people. As long as Xining has something to do, once it is attacked by the enemy, the Tiance Army can quickly arrive in Xining with countless guns, cannons, food and grass within seven days, and then quickly enter the battle. Your Majesty is the person who leads the army. I think it is better to know more than me, the reason why the troops are fast before they move, and the soldiers are more powerful. In this way, where is the border of my Tang Dynasty? As long as the Tang Dynasty is willing, anywhere is the border of my Tang Dynasty, and any military horse can be used as reinforcements."

Li Shimin only understood a little about economic role after listening to Chen Zhengtai’s words.

But in fact, Chen Zhengtai doesn’t need to explain the military role, Li Shimin already knew it.

In the past, the most difficult thing in combat was not to fight, but to raise and dispatch the food of countless people. A hundred thousand troops had to be requisitioned in advance for hundreds of thousands of civilians to transport grain and provide assistance.

But now... if I had this, would it take several years to win the world? I, Li Shimin, have this... Who can match the world?

Li Shimin opened his tiger eyes and couldn't help but say excitedly: "This kind of magical thing is worth tens of millions of coins, even hundreds of millions of coins."

This is his feelings!

At this time, Li Shimin touched the steel structure of the coal stove room. This dark, heavy and thick thing rubbed in Li Shimin's palm, and felt an indescribable feeling.

"How to park this car?" Li Shimin suddenly remembered such an important question.

"This..." Chen Zhengtai said: "For the time being... there is no brake device installed yet, so... the stove stopped and the car stopped."

Li Shimin: “…”

Chen Zhengtai immediately ordered, and the strong men immediately stopped adding coal to the furnace.

Sure enough... After the steam continued to spew, the steam began to become thinner, and the steam train screamed. The train's speed became slower and slower. In the smoke, it finally slid to the last bit of strength and stopped steadily.

When he stopped, the car shook again, and Li Shimin was not firmly in his foothold and staggered.

However, he obviously didn't care about this. When he looked back, he saw Zhang Qian still had a pale face, holding the steel pipe tightly, and laying on the deck, so scared that he didn't move.

Li Shimin couldn't help but look at Zhang Qian with contempt, then he looked at Chen Zhengtai and said, "Who made this car...?"

Chen Zhengtai said: "There are not only two people who made this car. There are too many parts and various skills involved in this car, and they are all the result of collective efforts. However, the one who undertakes this huge project is Erchen's secretary."

"secretary……"

Li Shimin suddenly remembered that Chen Zhengtai seemed to have a secretary. Zhang Qian once reported that when Chen Zhengtai was at home, he always liked to run into the study, and said that this person... It is said that he was Chen Zhengtai's closed disciple. Oh, yes, that case leader... Li Shimin's memory suddenly became clearer and clearer.

Li Shimin said, "I remember he was just a little girl."

At this time, a fair-skinned man stood up from behind Chen Zhengtai and saluted Lee Shimin: "Your Majesty, the civilian girl is indeed a woman."

The train was just now, and Wu Qi boarded the train, but he was wearing men's clothes, and at that time, no one paid too much attention to such a person who looked like a follower.

Li Shimin looked at Wu Xi and felt familiar. Then he laughed and said, "I never thought that you were here too. Did you make this car?"

Wu Qi hurriedly said: "The young lady is the disciple of his teacher. All the ideas of this steam locomotive were proposed by his teacher. The young lady was just Xiao Gui and Cao Sui, who acted according to his teacher's instructions. Moreover, there were hundreds of people from the institute around him who worked together. How could it be said... this was made by the young lady?"

Li Shimin felt it was reasonable, so I just said it.

He glanced at Chen Zhengtai. Chen Zhengtai...at least one thing is good, but he doesn't take credit. If it were someone else, if he had any credit, he would have been broken long ago. Why would he be so humble?

Li Shimin looked at Wu Yu deeply. He always felt that Wu Yu was not simple, and... he seemed to remember that when Wu Yu was on the train, he always stuck to Chen Zhengtai at any time. At the beginning, he only felt that it was narrow-minded and unable to use it, but now if you think about it carefully, you know what kind of complacent relationship between them is.

When Li Shimin thought of his son-in-law doing such a thing, he felt a little unhappy.

But after careful consideration, I am many times better than Zhengtai in doing such a thing, and there are 3,000 beauties in my harem.

So... my mood became a little calmer again.

But he still said with a stern face: "Wu Xi."

"The girl is here."

"In any case, this is also a great achievement. If the country has this thing, how can there be a reason for the future to be unrestrained? I never expected that there would be such a magical thing in the world... In any case, this car was also made by you uploading it. This contribution... is quite a big deal. I have heard that you are a loyal and kind person, right?"
