In the lesson that Emperor Chongzhen taught the crown prince, he looked forward to the future, and described the scenes, such as a car that can travel day and night tirelessly, a ship that can sail automatically against the wind, someone who can fly in the sky, and so on, can walk a long, long way in a day and night.

At that time, Emperor Chongzhen shocked many people when he said it, but everyone just listened. Although it was said by Emperor Chongzhen, at most it was only doubtful.

But with the construction of the steam engine, seeing that there will be power to burn coal, some people have already believed it. Now, when Emperor Chongzhen once again came up with a good thing called "cement", which can be used to build roads, they are even more convinced that the emperor is really not just talking.

Looking at the demeanor of these courtiers in the Wenhua Palace, Emperor Chongzhen once again emphasized: "As long as the natural knowledge that I have taught can be fully grasped and applied, I can say that what you said before will be presented to the world at an accelerated pace." When the time comes......"

Speaking of this, he himself was a little yearning, and said affectionately: "...... If I go to the south to conquer in person, I only need to lead the army into the car, sleep and wake up, and I will already be in the south. Our firearms do not need to be so troublesome to reload and shoot, but as long as the trigger is pulled, the lead bullet will be continuously fired. The shells are no longer solid, but will explode when they fly out and hit the ground. And it's not just such a short distance, it's the ability to hit invisible distances. Also, our ships can no longer sail not only on the surface, but also in the water, attacking the enemy from underwater......"

Emperor Chongzhen looked forward to the future again, and immediately shocked the ministers in the Wenhua Hall again. But some of these things are really hard for them to imagine.

Finally, a governor of the Governor's Mansion of the Five Armies couldn't help but play to Emperor Chongzhen: "Your Majesty, the last general can't figure out how this boat can swim in the water, and it's not a fish!" ”

For them, this is outrageous.

When Emperor Chongzhen heard this, he immediately retorted: "Fish can swim in the water, why can't boats?" Do you know why fish swim in water? If you figure this out and imitate it when you build a ship, how can it not work? ”

"......" His words not only made the military general stunned, but also the other civil officials in the Wenhua Hall couldn't say it.

What can a fish swim in the water, both on the surface and in the water?

Seriously, these doctors really haven't thought about this question. It's like fish swim in the first place, so why is that?

Emperor Chongzhen looked at them and knew their shock, so he explained to them: "I can tell Qing and the others that the reason why fish can swim on the surface and underwater is because there is an organ in the belly of the fish called the swim bladder, which is the air sac. By adjusting the air inside, the fish can switch between the surface and the water, and the air inside also helps the fish breathe. ”

After explaining the principle, he stared at the shocked courtiers and continued: "If we make the boat like a fish, and change its buoyancy by inhaling or expelling water, will we be able to make the boat like a fish?" ”

In fact, in the Western world, such an idea has already been proposed, and it has already been put into practice. Of course, if the original history is followed, the first submarine that can be used in real combat will not appear until the American Revolutionary War. And the submarine that can successfully blow up enemy ships will not be until the time of the American Civil War.

At this time, after listening to Emperor Chongzhen's words, these courtiers in the Wenhua Hall were all shocked, and listening to the emperor's eloquent talk, it was as if they had really seen this kind of thing. And not only this, but also what kind of ships, automobiles, etc., it seems that the emperor has also seen them.

At this time, they couldn't help but think of the earth-shaking changes that the emperor had had since Taizu Tuo's dream. Therefore, they immediately attributed Emperor Chongzhen's erudition to the fact that Emperor Taizu of Heaven brought the current emperor to heaven, and after seeing the situation on the side of the immortals, there would be such an unbelievable statement.

In the Wenhua Palace, many people have made a decision. After the scattered dynasty returns home, he must see with his own eyes whether the fish has the kind of air bag in the stomach of the emperor said.

At this time, although they have not seen it, they are basically certain, absolutely there is.

While they were thinking about it, they heard Emperor Chongzhen raise his voice and emphasize again: "At this time, the Qing and others should know why I want the crown prince to take the lead in applying natural knowledge and joining the scientific expedition. I can say again that if this knowledge of nature is studied more and applied to it, it will definitely change us dramatically. When that time comes, don't say that the territory of the Ming Dynasty is now doubled, and there will be no saying that the whip is beyond the reach of the whip! ”

Speaking of which, in the end, it came back to the matter of territory, and the courtiers in the Wenhua Palace really understood, it turned out that the emperor was explaining from beginning to end why he no longer set up the Xuanwei Division, but set up a province directly under the jurisdiction of the imperial court.

Seriously, seeing that the emperor was so persistent in saying these things, Xue Guoguan's stinky problem was committed again, and he said to Emperor Chongzhen: "Your Majesty, even if the imperial court can manage those places, but those places are barbarian lands, and the production is limited, even if the imperial court can collect taxes, how much money can it have?" ”

It is worthy of being called a stone in a pit, and there is no eyesight. Just because the emperor likes to expand the territory, it's enough, you still mind the question of how much tax you can pay, isn't this unpleasant for the emperor!

In the Wenhua Palace, many people thought so in their hearts, and they were also a little gloating.

This Xue Guoguan firmly holds the position of the first assistant to the cabinet. Now that the national strength of the Ming Dynasty is thriving, from the chaotic times like the end of the dynasty, it has suddenly reached a state of prosperity and prosperity that is more prosperous than the prosperous era in history. How can Xue Guoguan have such a good opportunity?

However, they didn't expect that Emperor Chongzhen was not annoyed by Xue Guoguan's question, but replied seriously: "I believe that among you, as well as the court and the people, there will inevitably be such questions. Not to mention the south, just the north, I even want such a cold place, and I have to belong to the three tribes of Mobei, there must be some people who can't understand it, thinking that I am a great joy, for my face! ”

At this point, he paused and glanced at the ministers below.

As soon as they heard what he said, these civil and military officials below didn't have the courage to do so, and hurriedly said something like "don't dare".

Emperor Chongzhen sneered in his heart, it was really not sincere at all. However, on the surface, he did not show contempt, let alone anger, and only explained lightly: "Have you ever thought that the steam engine and the like are powered by burning coal, and the more vigorously it burns, the more power it will produce. One day, there will be something in the ground that can replace this coal, making the fire burn more vigorously. What I described before must also be achieved with a higher motivation, and it is not enough to burn coal......"

Hearing this, Xue Guoguan couldn't help but ask in surprise: "Your Majesty, but the black oil in the ground, the fierce fire oil?" ”

Oil has been discovered and used by humans for a long time, but it is only limited to places where it can be produced. However, within the jurisdiction of the Central Plains Dynasty, there are very few such things.

Later, although it was used for transportation, it was ultimately inconvenient, so it could not become the main force used for combustion. Generally speaking, it is still mainly wood, supplemented by coal, and oil is ignored.

But at this time, Emperor Chongzhen mentioned it like this, then these courtiers in the Wenhua Hall can be said to be one of the most knowledgeable people, and they can naturally associate it.

"Yes, Xue Qing is right!" Emperor Chongzhen nodded and affirmed: "It's this fierce fire oil." After refining it in the future, it can burn even more. The resulting power can make the car and ship drive fast, and the machine can fly to the sky with people. When that time comes, I can tell you that our daily lives are inseparable from this fiery oil. Gold is precious, right? And this fierce fire oil is more precious than gold! ”

Hearing him say this, these courtiers in the Wenhua Hall suddenly fell into a stupor again. It's a little unthinkable for them, is that really going to be the case?

If Emperor Chongzhen said these words eleven years ago, they would think that the emperor was crazy and talked nonsense. But now, after so many years of foreshadowing, coupled with the emperor's prestige, and the reasonable and reasonable prospect of the future for them, to be honest, although they dare not be 100% convinced, no one dares to deny that the emperor said all this!

At this time, most of them confirmed a guess more and more. is all this described by the emperor, absolutely heavenly. Otherwise, the emperor would not be so sure, and talk as if he had seen it with his own eyes.

Thinking of this, their worldview collapsed again, could it be, there must really be immortals, there must be a heavenly realm, right?

Emperor Chongzhen didn't care what these people were thinking, he raised his voice again, and emphasized loudly: "And those so-called wild places, there are actually countless fierce fire oils underground. Now undiscovered, I went to take possession of it in order to rob our children and grandchildren of resources. It is so that our children and grandchildren can enjoy the benefits brought to them by our efforts, so that they can always lead the world! ”

Speaking of this, he saw that many of the stunned courtiers below had come back to their senses, so he said solemnly and earnestly: "The matter of expanding the territory will always be in the future, because I know that there are still many places, and there are more fierce fire oil buried underneath, which can be enjoyed by our children and grandchildren for hundreds of years!" ”
