    Finally someone couldn't help but asked aloud.

    This person is Li Jing, because he still bet with Li Shimin!

    At this moment, everyone's eyes were on Lin Xuan.

    "This is a steam train!"

    Lin Xuan looked around and announced proudly.

    "This thing is a magical thing that can make a hundred thousand troops reach Yanmen Pass within a day!"

    "After it is started, it can travel up to 320 miles within an hour!"

    Li Jing said in astonishment: "What?!"

    "320 miles per hour!?"

    Li Shimin's eyes widened, with a look of astonishment on his face, "Twelve hours in that daywouldn't it be possible to travel three or four thousand miles?!"

    Yuchi Jingde on the side said in disbelief: "How is this possible?!"

    "Flying three thousand miles a day?"

    "Am I dreaming?"

    Lin Xuan smiled slightly.

    "You are not dreaming! It is indeed in reality! You heard it right!"

    "This steam train can travel three thousand miles a day, it is absolutely true!"

    "One day is enough to drive from Chang'an to Yanmenguan."

    Lin Xuan said happily.

    Li Shimin's eyes turned to Li Jing, and he said triumphantly with a half-smile: "How?"

    "Duke Wei, have you already lost?"

    "The Azure Dragon King can't tell lies, the data he gave can stand the test!"

    "If you don't believe me, we can verify it right away!"

    The voice just fell.

    Li Jing touched his nose, and said helplessly: "Since Your Majesty has said so, it must be true what the Azure Dragon King said"

    "The facts are right in front of our eyes, and the future general can't have the slightest doubt."

    This Lin Xuan directly took out something beyond his cognition, which made him want to refute, but he didn't know where to refute!

    "Well, the last general is willing to be the vanguard. As long as I can contribute to the Great Tang, I, Li Jing, will not care if His Majesty asks me to take up any position."

    "Wait a minute." Li Shimin said suddenly.

    "Your Majesty, the 'steam train' invented by King Qinglong, how many people can it carry at one go?"

    Li Jing asked curiously.

    "Also, how much raw material does it need to consume once it starts?"

    "But I don't believe it. It doesn't take much to drive such a huge monster That must be a huge number, and we may not even be able to bear it?"

    Li Jing speculated with a face of course.

    As soon as this remark came out.

    Lin Xuan was slightly taken aback when he heard the words.

    Unexpectedly, a military general like Li Jing would be a bit ahead of his time, knowing "energy conservation"?  !

    "Yes, to start this train, the energy required is massive."

    Lin Xuan responded lightly.

    "Why do I call it a steam train?"

    "As the name suggests, it needs to boil water to maintain its power!"

    "Actually, boiling water is just a process. The real key is the water vapor obtained from boiling water"

    "This water vapor can move the piston and make the train run."

    "However, you may not understand this."

    "Anyway, all you need to know is that it relies on the water vapor obtained from boiling water to propel it forward."

    "And in this world, what boils water the fastest? And the most efficient? It is naturally coal."

    "So, the energy it needs to consume is coal!"

    "I explain it this way, can you understand a little now?"

    Lin Xuan explained eloquently.

    The voice just fell.

    "Coal?!"

    Li Shimin frowned slightly when he heard the words, and said with a puzzled expression.

    "As far as I know, there is such a thing as coal, but it is not an easy task to get it out"

    "There are not many coal mines in Datang."

    In Datang, coal has not yet entered the public's field of vision, and it has not yet entered the homes of ordinary people at all.

    Most people still use firewood to light fire.

    In fact, even in later generations, coalAfter the charcoal resources are sufficient, not many ordinary people will use coal, and most people still burn wood for fire.

    The large-scale use of coal is mainly in industry.

    But now, there is no industry at all, so where does coal need to be dug?

    "Not much? That's because you didn't go to find out, and you don't have the need to do so!"

    Lin Xuan said calmly.

    "Our Datang's coal resources can be said to be the most abundant in the world!"

    Lin Xuan said proudly.

    Thinking of those local coal bosses who casually become upstarts in later generations, what Li Shimin said at this moment seems a bit ridiculous.

    Datang has no coal?

    Then there are not many places in the world that have coal resources!

    Li Shimin frowned when he heard the words, shook his head, and said in a helpless voice: "But even if there is, it may not be an easy task to mine this coal"

    "During winter, charcoal is indeed burned in the palace for warmth."

    "It's not easy to get the charcoal out. Some of it was picked up in caves. I collected coal a few times and buried many people to death!"

    They don't even think about mining coal now, but there is indeed a little demand.  (Remember the site URL: www.hlnovel.com
