"This guy is big, but how can he pull people and goods?"

Li Er questioned.

At the beginning, this kid said that he could carry the army, but he observed for a long time, and he didn't see where he could fit so many people.

"This is just a locomotive, and there are many carriages behind him, which can carry people and goods!"

Zhao Yin gave a brief introduction.

"And how fast can this train go?"

After listening to his explanation, Li Er also understood a little.

"If it's empty, it's about 200 miles a mile a month!"

Zhao Yin secretly calculated in his heart and reported a number.

The speed of the steam train is about 50 kilometers per hour, that is, 100 miles per hour, and an hour is 2 hours, so it is definitely not an exaggeration to travel 200 miles per hour.

"Is it okay to travel thousands of miles a day?"

Li Er groaned for a moment and said excitedly.

"If you load cargo, it will affect the speed of ......!"

Zhao Yin thought for a while and continued: "In about five hours, you can reach thousands of miles away!" ”

"Really?"

Hearing this, Eldest Sun Wuji's eyes widened in surprise.

"If it's really as the horse master said, if you send troops to fight in the future, you won't have to worry!"

Wei Zheng, Fang Xuanling and others also nodded again and again.

Although they didn't know what the train was, they immediately realized that it was a good thing when they heard that it could carry people and goods and run so fast.

"Hehe, the colt is really powerful, and he can actually study tireless horses!"

The eldest grandson Wuji was immediately overjoyed.

"Quick, let me see how fast this big guy runs, haha......!"

Li Er waved his hand, and he couldn't help but be curious.

"Yes, we want to open our eyes and see how amazing this train really is!"

The eldest grandson Wuji also chimed in.

None of them have ever seen a train, no matter how good Zhao Yin says, it is not as enjoyable as watching it once!

And Zhao Yin originally planned to send someone to invite Li Er, but since he came by himself, he also saved himself trouble, so he immediately ordered the craftsmen just now to return to the cab.

And the craftsmen are also very happy, this kind of big guy, they are the first time to open, looking at the envious eyes of other craftsmen, a sense of accomplishment is born!

With the experience of the last time, the craftsmen already seemed to be familiar with the operation this time, and after a while, the train began to smoke columns!

"Your Majesty, we have to step back, this steam engine is about to start working!"

Zhao Yin stretched out his hand and pushed Li Er back.

"What? Is this train dangerous? ”

Li Er seemed a little surprised and asked in shock.

"Well, this steam engine has just been developed, and it is the first time it has been installed on a train, so it's better to be careful!"

Zhao Yin nodded.

Hearing this, the eldest grandson Wuji and others hurriedly came to persuade Li Er to retreat, this is the son of heaven of Datang, if something really happens, Datang will be in turmoil!

"Uh......h Woo......! ”

By the time they reached a safe area, the train had already whistled, startling Li Er and the ministers.

"Good guy, not only is this thing huge, but it's also so loud? No wonder the Wannian County Order mistook it for a giant beast! ”

Li Er looked at the train that started slowly and said with a smile.

"It's moving, Your Majesty, this thing really moves!"

Cheng Yanjin pointed to the train excitedly.

Although Zhao Yin had already told them the principle of train operation just now, they were still shocked to see that this behemoth could run on its own.

"Horse, this train seems to be a little slow!"

Wei Zheng looked at the train that had just started and asked suspiciously.

"It's good for such a big guy to walk on his own, how fast can you expect it to run?"

Without waiting for Zhao Yin to speak, Wei Chigong stood up and replied with a displeased face.

"Don't worry, the train needs to speed up slowly, just wait and see!"

Zhao Yin explained confidently.

With his words, everyone stopped making a sound and quietly watched the train gradually increase in speed.

"Get on the horse, let's chase the train!"

Watching the train gradually move away, Li Er commanded the people behind him.

So, the group quickly turned on their horses and ran after the train.

"This guy is really fast!"

Li Er excitedly followed behind the butt of the train and clamped the horse's belly.

Unfortunately, the tracks were only ten miles away, and after a while, the train began to slow down.

"That's it?"

Li Er, who hadn't enjoyed it yet, listened to the sound of brakes from the wheels and said unsatisfied.

"This section is only used by the son-in-law to test the train, so the construction is relatively short, which is also to save His Majesty money!"

Zhao Yin smiled.

"This train is such a good thing, it can run so fast with just some coal, and it is tireless!"

Li Er rode to the side of the train, looked up at the huge locomotive, and said this with emotion.

"You can build railroad tracks, it's too expensive!"

The head of the household department was the first to think of the problem of cost.

"It's okay...... this!"

Li Er was still immersed in the shock brought by the train, and continued: "My Datang now has a rich treasury, and this bit of railway track can still be repaired, if the railway can be repaired to the northern Xinjiang, it will be much more convenient to control it!" ”

"Your Majesty is right, the train can travel thousands of miles a day, and it is indeed an artifact for transporting supplies!"

Seeing that the emperor had already nodded, Dai Xuan no longer dissuaded, after all, it was not his family's silver, he was just managing it on his behalf.

In addition, this train does not have other disadvantages except for the high cost.

"Well, the railroad tracks need to be repaired, and the trains need to be built!"

Li Er made a decision immediately.

"Your Majesty is wise! With the train, I will definitely go further! ”

The eldest grandson Wuji also praised it at the right time.

"It's really an old yin, and the sycophants are loud!"

Cheng Yanjin glared at him with disdain.

"The old man is just talking about things, what? Do you think this train is bad? ”

The eldest grandson Wuji's face was pulled, and he crossed his waist and asked.

"Okay, what's wrong? It's just that we don't have your sycophants! ”

Cheng Yanjin was holding a big belly, still with that disdainful look.

"Okay, don't make any noise, this matter is settled!"

Li Er can't wait to build the railway now.

"Your Majesty, where do we go first?"

Zhao Yin thought for a moment and asked a crucial question.

At present, trains have just come out, and there are not many people who can build railways, so it is impossible to build two railways at the same time.

"This ......! I have to think about it! ”

One sentence stopped Li Er.

"Don't worry, Your Majesty thinks slowly, building a railway is not a day's work, it will take at least a few years!"

Not to mention that he is in the technologically backward Datang, even in the later generations, it will take a long time to build a railway.

Therefore, he said that a few years is not an exaggeration at all.
