"Good guy, this thing is full of iron, how much does this have to weigh?"

Forgetting the big guy in front of him, Xue Rengui's eyes widened in surprise.

"Yes, Master Horse, this train has at least 100,000 catties, not to mention traveling thousands of miles a day, even if it moves, I'm afraid it will be hard, right?"

Lin Wu also raised doubts.

Before assembling it, he only thought that this must be a big guy, but he didn't expect that after assembling, it would be even bigger than he thought.

"Don't you even believe what this colt says?"

Zhao Yin clasped his hands in front of his chest and said confidently.

In fact, they are understandable for questioning, after all, the transportation in this era is very backward.

But trains can be seen everywhere in later generations, so he is also very confident.

"Uh......! It's not really, it's just that the train is too big to be driven by the steam engine in front of it. ”

Although Lin Wu knew that the train was powered by a steam engine, he was still a little skeptical.

"Then let's wait and see......!"

After Zhao Yin smiled confidently, he gave an order to the craftsmen beside him, "Add coal and water to the locomotive!" ”

It's useless to just talk about it, it's a mule or a horse, and you have to pull it out and slip it!

"Yes!"

The craftsman gave up his orders and hurriedly added the prepared coal and water to the locomotive.

After about half an hour, the fuel was fully filled.

"Start the test drive!"

Zhao Yin waved his hand and said.

However, Lin Wu and all the craftsmen looked at each other, and none of them moved.

"Let's go!"

Zhao Yin repeated it again, looking a little impatient.

"Master Pony, we don't know how to start it!"

Lin Wu made a bitter face and muttered weakly.

As soon as his words came out, Zhao Yin also froze.

The point is, I can't open it myself, it's too embarrassing!

However, he immediately thought of the universal search and hurried up to search for the driving method of the train.

Thankfully, there are driving instructions on it, but they are only instructions, and there are no specific how-to videos.

However, it may not seem very complicated!

"Come with my horse!"

Zhao Yin put away the universal search, walked to the cockpit with the craftsmen, and explained to the craftsmen according to the method he had just found from the universal search!

"Got it?"

Zhao Yin looked at the craftsmen and asked with a little weakness.

He just read it out, but in the end, the craftsman had to try it out to see if it worked!

"Got it!"

The craftsmen nodded.

They are all top craftsmen in Datang, so their receptivity is also first-class!

"Then try it!"

After leaving the craftsman behind, Zhao Yin and Lin Wu walked out of the operation room of the train.

Then, the craftsmen began to light the fire according to the method that Zhao Yin had just taught them.

But the steam train does not start when it is ignited, but it has to boil a large amount of water in the locomotive to use its power!

Zhao Yin waited outside for a long time before he saw a puff of green smoke coming out of the locomotive, "The train is finally about to start!" ”

"All step back!"

For everyone's safety, Zhao Yin motioned for the others to step back.

After all, this is the first time the steam engine has been used, and if it explodes, the consequences can be very serious.

"Start!"

As soon as Zhao Yin gave the order, the soldiers in the distance began to wave the small flag in their hands, signaling the driver in the train to start the train.

"Uh......h Woo......! ”

Suddenly, the train emitted an earth-shattering whistle, which frightened everyone, some of them were timid, and even began to tremble, even Xue Rengui, who had seen artillery and earth buds, was a little nervous, staring at the locomotive.

Of course, Zhao Yin is the exception of these people!

"The train ......! Is this going to start? ”

Lin Wu was the first to react from the fright, then stared at the train and said excitedly.

He will be a young eunuch, and he has also taken the lead in researching a lot of new gadgets, although they are all gadgets, but they have also brought a lot of convenience to Datang.

If this big guy really doesn't need external force to travel thousands of miles a day, it will definitely be a huge change for Datang!

"Click...... Click! ”

As the bearings of the train turned, the train began to move forward and gradually accelerated, like a giant monster, galloping on the tracks!

"It's ......! It's really moving! ”

Everyone exclaimed.

"I really didn't expect that this steam engine would be so powerful that it could drive this hundreds of thousands of catties of giant iron!"

Looking at the speeding train in front of him, Lin Wu sighed excitedly.

"Hurry up and get on the horse!"

Zhao Yin flew on the horse and chased the train with everyone.

This steam locomotive, when empty, has a speed of about fifty kilometers per hour, so it is still possible for them to catch up with them on fast horses.

However, no matter how fast the horse is, it will not be able to travel thousands of miles in a day, after all, it still needs time to rest and feed the forage!

If you send troops to fight, not to mention that there are fewer cavalry, even if it is all cavalry, it will not be able to withstand a long-distance attack, but trains are different, as long as there is enough fuel, it is no problem to travel day and night.

When he first attacked Goguryeo, if there was an artifact like a train, why did he delay on the road for so long?

It was precisely because he was very tired from the carriage that he decided to study the train when he came back.

What's more, now the territory of Datang is getting bigger and bigger, and it will conquer the west in the future, if there is a train to transport troops, it will be twice the result with half the effort!

"Uh......h Woo......! ”

Zhao Yin and others have been following behind the train, but because it is still in the testing stage, the track has only been laid for ten miles, and after a while, it will come to an end.

The train slowly came to a halt as the craftsmen inside the train began to brake.

"It really worked!"

Everyone cheered!

"With this train, wouldn't it be very easy to transport soldiers and grain and grass when you fight on the battlefield in the future?"

Xue Rengui couldn't help but open his mouth in admiration.

"That's right, as long as there is this train, even if it is thousands of miles away, my Datang can be reached in one day!"

Zhao Yin nodded at him.

At the same time, he couldn't help but sigh that this Xue Rengui was worthy of being a famous general of the Tang Dynasty, and he could find out anything that was helpful to the conquest as soon as possible.

"Master Horse, this train is so powerful, I wonder if it can run all the time as long as you give it coal?"

When the craftsman who drove the train came out, while praising it, he also thought of a crucial question.

Trains are very expensive, and if they are combined with endless rails, the cost is even greater, and if they can't travel day and night, it's useless to build them, so it's better to buy more horses!

"That's nature, when the carriage is built, and then the carriage of coal is brought in, it is no problem to run as far as you want!"

Zhao Yin looked at the locomotive with satisfaction, and he already thought of the freight trains of later generations.

"That's a pretty good ......!"

The craftsman looked at the locomotive again, his eyes full of yearning.
