Emperor Chongzhen stood up, walked to the edge of the drawing, and then said to the prince: "Don't underestimate the use of this force, I can tell you."

When Zhu Cilang heard this, he immediately showed a sense of being cautious.

When others heard this, they held their breath, thinking that the emperor would say something else.

Emperor Chongzhen pointed to the drawing and said, "Look, if this force can be used like this, he can use fixed force to smash things. This can be applied to forging, or other aspects that require heavy force to smash things..."

Hearing this, many people, especially those civil officials, couldn't help but look at each other. It turned out that the emperor was so grand and mysterious, and he used it to teach the prince. In front of so many people, it turned out that it was just a craftsman's job? At most, this kind of thing was called a blacksmith, so that's almost the same, right?

After all, those who were involved in military and national heavy weapons did not have a special feeling. But at this time, they were actually blacksmiths, so they were speechless.

Although Emperor Chongzhen had issued an order to give craftsmen different titles to distinguish skills and identities, the craftsmen's low status has never been changed at once.

Therefore, even when Zhu Cilang heard this, his face showed a hint of contempt.

Emperor Chongzhen saw it and suddenly withdrew his hand and said to him: "Do you think this is a minor path? As the prince, you don't need to care about this?"

"My son, don't dare!" Zhu Cilang was shocked when he heard this, and he quickly bowed and responded.

It’s also a blessing that he is a flower in the greenhouse, otherwise it would be impossible for him to show his expression if he thinks in his heart.

After hearing this, Emperor Chongzhen did not blame him, but said to him: "Don't underestimate the relationship between blacksmiths. Dig out iron ore from the deep mountains, melt it into iron and steel, and then make it into swords, guns, armor, cannons, and cannons, and cannons, and cannons, and cannons, and even use it for houses, bridges, etc. I can tell you clearly that there is a big measure of whether a country is strong or not, which is whether the country's steel production is high enough and whether the steel utilization level is high enough. If the Ming Dynasty wants to be strong, it must pay attention to everything related to this iron!"

Zhu Cilang may not feel deeply about Emperor Chongzhen's words, but the important officials and generals of the court were shocked. The civil officials naturally thought about people's livelihood, while the generals thought about military affairs. Not to mention, the use of steel is indeed very important.

In fact, they also had this understanding in the past. However, they did not have the ability to clearly raise the steel-related things to such a high level like Emperor Chongzhen. Think about it carefully, isn’t that the case!

Not to mention the distance, we will talk about the war with Mongolia. Why did the Mongolians basically not have much threat to the Ming Dynasty? It was because the Ming Dynasty imposed an embargo on Mongolia and other items. So much so that they did not have enough iron materials to make arrows. Many bows and arrows were ground by bones. In this way, how could such bone arrows pose a threat to the Ming army soldiers wearing iron armor?

"My son has written it down!" When they were all thinking about it, Zhu Cilang responded to the emperor.

After hearing this, Emperor Chongzhen did not look at how much attention the prince would pay after listening to it.

He then reached out and pointed to another set of pictures and said, "Look, this force can also be used for the wheel. This is even more useful. If it can be done, you can tie a rope to the wheel to pull things that are difficult to pull by human power, or in places where people are inconvenient, such as mines, pull things out and lift water up, and it can also be used for water conservancy irrigation, etc."

Speaking of this, Emperor Chongzhen suddenly raised his voice and continued to say to the prince: "It can also be used on the vehicle! Think about it, put this thing on the vehicle, the force is connected to the wheels, so that it can rotate. In this way, there is no need to pull the cattle and horse, and the vehicle can move forward by itself. In this way, this kind of car does not need to eat or drink, just burn the fire directly, tirelessly and fearlessly at night. What do you think?"

"..." Zhu Cixuan was stunned when he heard it. If he could not think too much about the previous things and could not shock him even more, then the vehicle that could only walk around would definitely shock him.

Not only him, but others, were also stunned. Can there be such things in this world?

After a while in the courtyard, a sound suddenly sounded in the crowd, a little bit small, but he was speechless and came back to his senses and shut up immediately. However, everyone present heard this sound clearly.

"Wooden ox and horse..."

Emperor Chongzhen also heard that the wooden ox and flowing horse should actually be a means of transportation such as a wheelbarrow or a human-powered one. Therefore, he said casually: "This thing is many times stronger than the wooden ox and flowing horse. Have you ever thought of anything?"

Hearing the question, Zhu Cilang came to his senses, stared at the picture carefully, and then said a little awkwardly: "Father, son minister... son minister is stupid!"

It was really because Emperor Chongzhen said too much, and he couldn't keep up with him. He knew that even if he said it, he probably couldn't keep up with his father's idea, so he simply admitted this.

After hearing this, Emperor Chongzhen guided him and said, "Look, if the force is strong enough, can it pull more than one car, but two cars, three cars, or ten cars, or hundreds? And it keeps pulling day and night. As for the speed, if it is not fast enough, I will find a way to make him faster. Then will the transportation between the southeast, south, west and north of the Ming Dynasty be much more convenient in the future? For example, if I want to lead troops to attack Liaodong, I will sleep with the soldiers on this car and arrive in Liaodong. Will it save time, effort, worry, and a lot of costs?"

"..." Emperor Chongzhen's words were too exaggerated to everyone in the courtyard. Is this possible?

Even a madman dare not think so, right? The imagination triggered by a teapot is so exaggerated?

These people would rather believe that the Jade Emperor was going to descend to earth than believe that the scene described by Emperor Chongzhen would really become possible!

Emperor Chongzhen looked at them all stunned. For some reason, he seemed to feel a little enjoyable in his heart, so he continued casually: "Also, if this thing is loaded on the ship and drives the paddle wheels of the ship to roll, will it have a very big effect like a vehicle, greatly changing the shipping of the Ming Dynasty? Do you still need to care about the direction of the wind when applied to warships..."

"..." Everyone continued to be speechless, is that okay?

The passage from Emperor Chongzhen's later shocked Zheng Zhilong, the pirate king. If there really was such a ship, it would not be affected by the wind direction, and if it could drive very quickly, then who would be the opponent of the Ming Dynasty on this sea?

At this time, he suddenly felt that the emperor said that the Ming flag would be flying at the end of the sea, because he had thought of this before?

I don’t know how long it took, but before Zhu Cixuan came to his senses, the chief assistant Xue Guoguan spoke first and said in a trembling voice: “Your Majesty, can this... really be done?”

When they heard the voices, almost everyone came to their senses. They all stared at Emperor Chongzhen, their eyes unblinking and their ears were erect, for fear that they would not be able to hear the emperor's answers clearly.

If the words that Emperor Chongzhen said just now were what the emperor said before the time travel, probably many ministers would advise the emperor not to think about it. If this words were said by ordinary people on the street, they would probably be called crazy.

However, this is what Emperor Chongzhen said today. Since the end of the eleventh year of Chongzhen, Emperor Chongzhen has shown extraordinary means since Taizu asked his dream, and his wise and powerful force are definitely not blown up. His current prestige is at its peak. Especially since he can guess what others are doing and what they want to do from the details, who would not admire the Ming Dynasty for such meticulous ability?

Now, he said this. Although people, including Xue Guoguan, found it incredible, they did not dare to insist that this was impossible!

After hearing this, Emperor Chongzhen said to Xue Guoguan with a smile: "I said I can do it, do you believe it? Instead of thinking, it is better to do it directly and practice it to see if it can be done. You can first verify whether this is possible from the perspective of knowledge, and then do it. When encountering difficulties, you think about solving the difficulties..."

Speaking of this, he saw Xue Guoguan and many others, and seemed to have a look of disappointment. He knew that the reason why they did not get a positive answer from him.

In response to this, he had to raise his voice and immediately said firmly: "I can also tell you clearly that this can be created. However, there will be many difficulties, but as long as it is created, our Ming Dynasty will have earth-shaking changes!"

After Emperor Chongzhen said this, the courtyard was still very quiet. Most people couldn't help but show a look of yearning on their faces. Is it really the day that they were created?

Suddenly, after Zhu Cilang came to his senses, he showed a eager look and said to Emperor Chongzhen: "Father, my son wants to give it a try!"

At this time, if the father agrees, even if those civil servants use the Four Books and Five Classics, the learning of the saints to suppress him will be useless. For a child who is only fifteen years old, it seems very interesting and fulfilling to create such things. His interest will naturally be aroused immediately.

After hearing this, Emperor Chongzhen ignored it, but walked to the next place of the object, pointed to Kongming lantern and said, "You should know this Kongming lantern, right?"

"My son knows that I have let it fly." When Zhu Cixuan heard this, he had to put down his previous request first and answer.

Others heard that because of the example of the teapot, most people knew that the emperor must have an incredible statement about Kongming lanterns. It is impossible to say that Kongming lanterns will fly to the sky with people, right?

Thinking of this in their hearts, they were curious about the conversation between the emperor and his son.

Emperor Chongzhen nodded and said to the prince: "Did you ever think that if this Kongming lantern is big enough, can it fly to the sky?"

"..." Hearing this, the people around him couldn't help but feel silent. Sure enough, the emperor was really thinking this way!

This time, Zhu Cilang was not as shocked as the teapot, but immediately said the truth: "I have never thought about it before, but when my father mentioned it, I thought it seemed that it was OK!"

Others nodded in their hearts, but they were still curious and didn't know what the emperor would say. They always felt that it would not be that simple for the emperor to mention this.

Sure enough, Emperor Chongzhen said to the crown prince: "Do you know what the reason is?"

"..." Zhu Cilang was stunned for a moment, a little unaware of how to answer, and finally had to say, "After ignition, it will float up and float to the sky."

"Why does it float after ignition?"

Faced with the father's questioning, Zhu Cixuan scratched the back of his head and said in confusion: "The turbid air is falling, and the clear air is rising?"

"..." This time, it was Emperor Chongzhen's turn to be speechless.

Forget it, don't ask that. Anyway, few people in this era will know it. So he said to the prince: "The air is like water, with buoyancy. If the goose feathers can float in the air for a long time and slowly fall, while the iron blocks and other things will drop rapidly, it is because the buoyancy of the air is too small. After igniting the air, the air expands under heat, and you can temporarily imagine that water turns into steam, and it will be easier to hold up the Kongming lantern. This is why the Kongming lantern will rise in the air."

When he said this, everyone was listening carefully. I have to say that the emperor's statement opened their eyes.

"Use this principle to make an object, heat it up, and the force of the rise can bring people to the sky. Then lower the temperature slightly and let it slowly fall like a feather, so that people can also land safely." Emperor Chongzhen said this, looking around, and finally looked at the prince and continued, "But what I really said is not just a Kongming lantern. You need to think about it and do it. I can tell you clearly that one day in the future, people will definitely be able to fly in the sky!"

After saying that, before the prince came to his senses, he took a few steps forward, picked up the bamboo dragonfly, spun it casually, watched the bamboo dragonfly fly up, and then said to the prince: "Look, this is another way of flying. So, what is the reason for this way of flying? Can you use this principle to make better things and take people to fly?"

After saying these things, Emperor Chongzhen slowly walked back to his position and sat down, looking at the dazed prince and said, "The things I just said are actually all the things I have explored in the Agricultural Department and the Kaiwu Department. You see, if you can understand and apply them, it will definitely change the Ming Dynasty and make the Ming Dynasty stronger. As the prince, you should know what you should guide? How to grasp the future direction of the Ming Dynasty and how to go in the future?"
