Amidst the shouts of several craftsmen on the ground, the firewood on the hot air balloon was extinguished, the hot air balloon lost its lift and gradually fell to the ground.
Zhang Guanghang, the Minister of Justice, looked at the hot air balloon that could rise and land at will, as if he were seeing a god, his expression was a little dazed.
Zhang Guanghang was sent by the emperor to commend Li Zhi. Li Zhi went to the south of the Yangtze River and killed Qian Qianyi, Zhang Shenyan and other national traitors. The emperor issued an imperial edict to praise Li Zhi.
Li Zhi had Han Jinxin inquire about the news and found out that Zhang Guanghang had also spoken a few words for him at the court, so he warmly entertained Zhang Guanghang and even let him see his hot air balloon.
After Zhang Guanghang saw the hot air balloon, he was very surprised and even lost his temper. This is not surprising because in this era, flying to the sky is an impossible dream. Because it is impossible, flying to the sky is often associated with religious beliefs.
Whether it is the flying gods of Taoism or the sky-controlling Arhats of Buddhism, being able to ascend to the sky is a kind of power of the gods.
However, in Li Zhi's case, a few ordinary craftsmen actually relied on the power of technology to fly into the sky that only belongs to gods.
Taoism was the state religion in the Ming Dynasty. In Taoist mythology, all the palaces of the gods are in the sky. As long as you can fly high enough, you can see the gods. When this hot air balloon flies, can it fly so high that it can reach the sky?
, chatting about home affairs with King Tota, and playing chess pieces with Tai Shao Laojun?
This made Zhang Guanghang surprised, surprised, and even a little scared.
As for the generals and officials under Li Zhi, although they were also surprised by the magic of hot air balloons, they were not surprised because they had followed Li Zhi for ten years and had seen all kinds of ingenious inventions.
Zhong Feng looked at the hot air balloon with a smile and said, "Master Guo, this hot air balloon is not safe or not. Zhong Feng, I also want to go up and take a ride!"
Li Xing spat: "Zhong Feng, you also want to fly into the sky? Do you think you will become a god if you fly up?"
Zhong Feng replied: "Li Xing, don't think that I, Zhong Feng, have never seen this hot air balloon. I stood by and watched when the Duke was drawing the drawings for those craftsmen. I know the principles of this hot air balloon better than you."
Hearing that Liaodong Commander Zhong Feng understood the principles of hot air balloons, Zhang Guanghang cheered up and hurriedly raised his ears to listen to Zhong Feng's explanation.
Zhong Feng coughed and said: "The Duke made it clear at that time that this hot air balloon uses the principle of thermal expansion and contraction. The flame is hot and can heat the air, making the air expand and become lighter. When the air becomes lighter,
When the cavity of the hot air balloon is filled, the entire hot air balloon becomes extremely light and can naturally float in the air due to the pressure of the atmosphere."
Hearing Zhong Feng's explanation, many of the old people under Li Zhi understood and nodded in agreement. These old people had been following Li Zhi for a long time and had more or less learned some basic scientific knowledge from Li Zhi, so they could naturally understand Zhong Feng's explanation.
But Zhang Guanghang was dumbfounded. Monk Zhang Er was completely at a loss as to what "air", "thermal expansion and contraction" and "air pressure" Zhong Feng mentioned.
Zhang Guanghang thought for a long time, and finally asked Zhong Feng: "Mr. Zhong, will this mortal fly so high that he will scare the gods in the sky?"
Hearing the words of Zhang Guanghang, the Minister of Justice, Li Zhi almost laughed out loud, but finally managed to hold it back.
Zhong Feng was stunned, and for a moment he was a little unsure. The Taoist belief in the Ming Dynasty was very popular, and several emperors themselves were Taoist priests who made elixirs to seek immortality. In the concept of Ming people, there must be gods in the sky. Even people like Zhong Feng were stunned.
In this way, Feng learned some basic scientific knowledge from Li Zhi, and did not give up his belief in gods. However, mortals ascended to the sky with the help of hot air balloons, which seemed to break the immortals' privilege of flying into the sky.
Zhong Feng hesitated and said: "The Duke of Guo is a god-like figure, and the gods in the sky must know it. When we work under the Duke of Guo, even if we disturb the gods, we will definitely be forgiven."
Zhang Guanghang nodded frequently when he heard Zhong Feng's explanation. Everyone trusted Li Zhi's power. Since Li Zhi was taught knowledge by Taoist priests from the seaside gods, he naturally had some connection with the gods in the sky.
Li Zhi was speechless when he heard Zhong Feng's messy explanation, and finally couldn't help laughing.
Li Zhi secretly wondered if it was time to start basic science education. But now Li Zhi's territory is hungry for new intellectuals, and the grassroots talents trained by the school are in short supply, and are being suppressed by officials at all levels, courts and tax bureaus.
Divide. Li Zhi really doesn’t have time for students to study physics and chemistry, because that will prolong the time for students to become officials.
However, Li Zhi wonders whether basic science education can be carried out among young children and craftsmen. If a group of craftsmen master basic science, Li Zhi's workload can be reduced. In the future, if Li Zhi invents any inventions, he will draw the drawings and give them to the craftsmen.
They, craftsmen can rely on the knowledge they have learned to make it.
Li Zhi was thinking there, and the hot air balloon had landed on the ground. In the cabin made of bamboo, Qi Liu, the head craftsman of the plate armor forging workshop, and four other craftsmen came out and bowed to Li Zhi with their hands raised.
"I've met the Duke, I've met all of you adults!"
Li Zhi smiled and patted Qi Liu's shoulder and said with a smile: "Qi Liu, what material is your hot air balloon made of?"
Qi Liu was patted on the shoulder by Li Zhi, and he was a little excited and said: "Master Guo, according to the drawings you gave us, we initially tried to sew a hot-air balloon with canvas. However, the hot-air balloon made this way leaked and did not fly.
Get up. We finally used tanned pigskin to make a balloon and successfully flew it."
Li Zhi walked to the hot air balloon, looked at it, and said with a smile: "How many times have you flown? Is it safe?"
Qi Liu replied: "I have flown more than thirty times recently, once every few days. There has been no accident."
Li Zhi nodded and suddenly said to Zhang Guanghang: "Master Zhang, I will fly up with you to have a look!"
Zhang Guanghang was stunned for a moment, his face flushed with excitement, and he asked nervously: "Can I fly?"
Zhang Guanghang regretted saying this. He felt like he was acting like a country bumpkin. After all, he was an official from the capital, so why did he act like a fool who didn't understand anything in a small city like Fanjiazhuang?
Li Zhi waved his hand and shouted: "Come on!"
In the envious eyes of everyone, Zhang Guanghang trotted into the cockpit with Li Zhi. Qi Liu laughed and burned firewood in the burning iron barrel. The hot air inflated the deflated pigskin balloon little by little.
Amid the exclamations, the hot air balloon took off and took Li Zhi and Zhang Guanghang into the sky.
Qi Liu and another craftsman vigorously shook the propeller behind the cockpit in the cockpit, trying their best to control the direction of the hot air balloon.
This kind of propeller has limited wind power and can only be used when there is no wind, such as today. If there is strong wind, it is better not to take off the hot air balloon.
The hot air balloon gradually flew up into the sky, reaching about a hundred meters above the ground. Qi Liu reduced the intensity of the fire, so that the hot air balloon no longer rose, but floated in mid-air.
Zhang Guanghang seemed a little afraid of heights, and his face turned pale as he stood in the cockpit. He mustered up the courage to stand on the edge of the cockpit and looked down, and saw Fanjiazhuang at his feet. After two expansions, Fanjiazhuang formed a right angle like building blocks at his feet.
Shape. Factories are dotted throughout the city, and horse-drawn carriages transporting raw materials and goods come and go.
Zhang Guanghang looked at the blue sky above, then at the city below, shook his head, and praised: "It's really a magical method." r
