"How long does it take ......?"

Li Er seemed a little surprised, "I really hope I can get on this train now and travel around Datang!" ’

"It will take a long time to build the railway, but the steam engine in this locomotive can work now!"

Looking at Li Er's regretful expression, Zhao Yin smiled.

The steam engine was the first of the industrial age, and with it, many other machines could be invented!

"Virtuous nephew, what else can this steam engine do besides driving trains?"

The eldest grandson Wuji asked suspiciously.

"It can also be used to mine ore and coal, much faster than manpower!"

Zhao Yin gave a simple example.

"Uh-huh......! This is good, now that Datang's steel plant has been established, it needs a lot of coal! ”

Wei Zheng nodded repeatedly.

"And there's more......!"

Zhao Yin smiled and gave examples to the ministers, "The steam engine can be used for weaving, pumping water, irrigating farmland, and so on!" ”

"Good!"

Hearing that the steam engine could be used to pump water, Li Er was very happy.

Fields are the foundation of the people's survival, if water can be pumped to irrigate the farmland, Datang will no longer have to worry about spring drought!

"Not only that, but you can also build a steamship, just like a train, and you don't need any external force to sail on the sea!"

Zhao Yin gave another example.

If it weren't for the fact that the Tang Dynasty did not have ships capable of crossing the ocean, how could the Japanese Kingdom come to provoke?

Moreover, if the steamship is really developed, the transportation capacity is not to be underestimated, and the cost is lower than that of the train, and the time is relatively short, after all, the ship does not need rails.

"Is it okay to just have coal and water?"

Li Er's eyes looked at Zhao Yin.

"That's right!"

Zhao Yin nodded affirmatively.

"If we can really develop a steamship, wouldn't it be faster for me to transport goods from north to south in Datang?"

Dai Xuan was immediately overjoyed.

"Virtuous son-in-law, start developing steam ships now, as long as the ships are built, we will wave the Japanese country and include it in my Tang Dynasty territory!"

Li Er has always been attached to the Wa Kingdom, if nothing else, because they proclaimed themselves emperor.

"Yes!"

Zhao Yin arched his hand at him.

This idea coincides with what he was thinking in the Pony Mansion.

Normally, a steamship is no less useful than a train, and sometimes a steamship is more useful than a train, especially in warfare.

This steel fortress driving on the sea will definitely become a nightmare for Western countries.

"I've seen the speed of the train, I don't know about your steamer?"

After hesitating for a moment, Li Er still asked.

There are also boats in the coastal areas of Datang, but these boats are too backward, and when traveling, they are limited by the weather, and they will be easy when the wind is downwind.

"Traveling thousands of miles a day shouldn't be a problem."

Zhao Yin pondered for a moment before he said slowly.

The steamships he studied were built after years of experience in later generations.

Even if the current technology is not very mature, he still dares to guarantee this speed.

"Not bad!"

Li Er calculated in his heart, if it is at this speed, from Chang'an to Yangzhou, I am afraid it will only take a few days, and if it is according to the previous speed, I am afraid it will take more than a month at the earliest.

"Your Majesty, there is one thing that you did not think of is that steamships do not need railways, so this will save a lot of money."

Dai Xuan hurriedly told what he thought of.

You must know that when the railroad was built, his heart was dripping blood every day.

If it weren't for the train's performance that amazed him, he wouldn't have supported any other proposals.

"You know, there are many waterways in the south, which are suitable for the development of steamships, but not in the north, there are not so many waterways, so the railway is the first choice."

Zhao Yin looked at Dai Zhou with a look of disdain, this old boy just wanted to save money, and he was reluctant to invest a dime, so he wanted to empty the white wolf here.

"Railways and steamships, I am determined to succeed, and we must perfect these two things in the shortest possible time."

The benefits that trains can bring are obvious, and in the same way, steamships are also indispensable to Datang, so he directly ordered it.

Although the soldiers of the Tang Dynasty have just triumphed, the treasury is not only not empty, but it is more abundant than in previous years, which is entirely because of the appearance of Zhao Yin.

Especially his whimsical plans, seemingly chaotic decisions again and again, can often be powerful.

This was the case with the Seven Great Families at the beginning, as were the surrounding countries, but now the threat no longer exists, the people live and work in peace and contentment, and Datang has reached an unprecedented tranquility.

However, they all know that Datang still can't relax, because overseas forces are still eyeing here.

"Your Majesty, there will be reaps only if there is investment, otherwise this money is just waste paper."

Li Er's decision still made Zhao Yin very pleased, an emperor, if he didn't even have this vision, then his country would not be stable for long.

"I still believe what the horse said, otherwise, Datang will still be worried about the lives of the people!"

After Zhao Yin finished speaking, Wei Zheng couldn't wait to stand up and add.

said that it was a supplement, but this old boy clearly came to hold Zhao Yin's stinky feet.

Of course, this is absolutely understandable, and now in Datang, waiting for such an opportunity, he is definitely not the only one, and it will not be the last.

Originally, Li Er planned to take another round of the train, but was stopped by Zhao Yin, seeing that the sun was about to set, waiting for the locomotive to be transported back, and he didn't know when it would be.

In desperation, Li Er could only reluctantly return, and on the way back, from time to time he did not forget to urge everyone to build the railway as quickly as possible, and there was no room for error.

The next day, early in the morning, Zhao Yin ordered someone to sort out the cost data of the railway and send it directly to Dai Guan's house.

Although the current railway of Datang is much simpler than that of later generations, the efficiency is still very slow.

Dai Xuan took the information and watched it carefully, not daring to be sloppy.

Li Er has already mapped out the route, which is from Chang'an to Luoyang.

Thanks to the Beijing-Hangzhou Grand Canal, Luoyang has already become the leader of the trade in goods in the south, and compared with other cities, I don't know how much more prosperous.

If there is no Zhao Yin's appearance, I am afraid that Chang'an will not know how many times behind there, and it can be seen from this how much His Majesty attaches importance to Luoyang.
