"Not in a hurry!"
Chongzhen waved his hand, looked up at the sky, and said calmly: "Since I have finished watching the flying thunder cannon and the effect is very good, then this trip has been successfully concluded. It is my turn next."
After saying this, without waiting for everyone's reaction, Chongzhen said to Cao Bianjiao: "Go and bring the gifts I brought, and let me show you this treasure."
"Xu Aiqing, please send an order to the sergeants patrolling around the valley. If they see anything for a while, they are not allowed to do anything. They will treat it as if they didn't see it!"
After the emperor said this, everyone remembered that the emperor had brought gifts. They were attracted by the power of the flying thunder cannon and temporarily forgot about it.
After waiting for about a quarter of an hour, Tao Dayong drove the carriage into the valley with four or five people, and stayed aside quietly, waiting for orders.
"Tao Dayong, let me show it to you!"
"yes!"
After Tao Dayong responded, he called on several craftsmen to start moving things from a carriage.
Folded cloth, stove, rattan stove, hemp rope, copper kettle...
Seeing the things that the craftsmen moved, the officials were a little confused, but the craftsmen assembled them in an orderly manner.
After about a stick of incense, the hot air balloon was installed.
I saw the man named Tao Dayong adjusting the stove, then holding the fire folder close to the mouth of the stove, and spurted out a stream of flames without any warning, scaring everyone's hearts.
Huhu...
The flames rose, and the ball sac slowly expanded. After a few breaths, a huge ball hung in the air.
I saw a huge five-clawed golden dragon painted on the surface of the huge ball. The huge dragon head looked down at everyone. The suspended ball and golden dragon gave people a great sense of oppression.
This golden dragon was specially painted by Chongzhen for the purpose of shocking.
In the midst of everyone's astonishment, Tao Dayong jumped into the basket and moved his hand. The flames sprayed became bigger again, and the golden dragon began to rise. Everyone's eyes also lifted as the golden dragon rose.
In a few breaths, the golden dragon disappeared from everyone's sight, and the huge ball was only the size of a millstone in everyone's eyes.
But for the sergeants patrolling the mountain, the pressure was greatly increased, because they happened to encounter the golden dragon hanging on the hot air balloon.
"Dragon, dragon... Lord Qianhu, I saw a golden dragon!"
"There really is a dragon, and it flew up with a person!"
"Shut up, be quiet, and don't look!"
The leader, Qianhu, swallowed hard and scolded angrily, but he still took a sneak peek.
The huge black sphere was like a sky full of black clouds, and the golden dragon seemed to have torn the void apart, leaning out from the black clouds and clawing hard at the ground with its front paws.
On the ground, looking at the petrified people, Chongzhen coughed a few times, waking everyone up.
Everyone who woke up looked at each other with confusion in their eyes.
"T-Teacher, fly, fly!"
"Um!"
"And he flew into the sky with someone else!"
"Saw it!"
"Teacher, this must be..."
"Be quiet, the teacher is not blind!"
Listening to Sun Yuanhua's shouting, Xu Guangqi had a headache from the noise and cursed angrily,
Then he stared at the hot air balloon in the sky, his eyes full of doubts.
For example, what kind of device is that fire-breathing device?
What is burning? Why do you do it right away?
How long can you keep the large Kongming Lantern in the sky with what you carry?
Why can you take people into the sky? What's the height?
What is the meaning of flying into the sky?
…
His doubts and curiosity also represent everyone's doubts.
After a while, Chongzhen said with a hint of joy in his voice: "Everyone, do you want to go to heaven and have a look?"
"Your Majesty, I want to go to heaven and see!"
"Your Majesty, I want to go up and have a look!"
While everyone was looking at each other, the curious voices of Bo Jue and Sun Yuanhua came out.
Seeing the curious expressions of his two disciples, Xu Guangqi stretched out his hand and slapped each of them, and said angrily: "What are you going to do? Is it time to go to heaven now? When Your Majesty is finished here, we will have plenty of opportunities to go to heaven!"
"My lords, after we have finished our research here, if you want to go to heaven, you can come at any time. I promise to meet your heavenly requirements!"
The six cabinet ministers looked at each other with wry smiles.
This is true, but it feels awkward no matter how I hear it. Is this sending them to heaven? Just send them away directly.
"Everyone, is this gift of mine okay? Is it an eye-opener?"
Is it okay?
It's just great.
My horizons have been opened to the sky.
The emperor's action was indeed extraordinary.
Xu Guangqi said in a deep voice: "Your Majesty, I am not sure about the principle of this, but it should be the same as the large Kongming Lantern. Does it have a name?"
"hot air balloon!"
"hot air balloon?"
Seeing that everyone was very surprised, Chongzhen added: "The principle of flying is to heat the air in the sphere, so it is called a hot air balloon.
You see, when heating, the balloon slowly inflates. When the flame becomes smaller, the balloon becomes smaller. This process is called thermal expansion and contraction of gas..."
"Thermal expansion and contraction?"
Chongzhen explained casually, and everyone seemed to understand but Xu Guangqi exclaimed, frowning, and mumbling something.
Chongzhen was very curious after seeing this scene, but he did not urge him. After a while, Xu Guangqi seemed to have come back to his senses.
"Your Majesty, I have heard of the term thermal expansion and contraction, and I also know the principle!"
Without waiting for Chongzhen to ask, Xu Guangqi continued: "I heard it from Matteo Ricci, and this term was not proposed by him. It seems that it was proposed by his good friend in Thailand (Italy).
It seems that the theory of calling, calling...gayue is not yet complete, and I didn't pay much attention to it when I said it. "
"Is your name Galileo?"
"Yes, yes...that's the name! Does your Majesty know it?"
This time it was Xu Guangqi's turn to be confused. Matteo Ricci died before the emperor was born. He must have never been in contact with Ricci, and the emperor had never been abroad. How could he know the name Galileo.
Xu Guangqi was confused. Chongzhen was even more confused than him. After being confused, he became excited.
Galileo was an absolute boss, a figure who had been taught in history textbooks and Chinese language textbooks, such as the experiment of "two iron balls falling to the ground at the same time" in the Leaning Tower of Pisa, but he really couldn't remember what era this boss lived in .
He has experienced multi-disciplinary research throughout his life and is known as the father of modern physics. He is not only awesome in physics but also in mathematics.
Such a big boss must come to Ming Dynasty or send someone to Italy to study.
But now is not the time to talk about this. Chongzhen suppressed the excitement in his heart and said softly: "Okay, the specific reasons cannot be explained for a while. The key point is why I personally study hot air balloons?"
