Qin Ming and others were filled with admiration when they heard Duan Lun's ambition!
After hearing this, several craftsmen stood up one after another, bowed their hands to Duan Lun respectfully and said:
"We are willing to ride for the minister and help him fulfill his wish!"
Duan Lun laughed loudly when he heard this and said:
"Okay, okay, okay!"
Li Chengqian looked at this scene with relief.
After Duan Lun and others calmed down a little, Qin Ming took them to the place where the road was being built.
After everyone walked for a while on the cement road, King Li Tai of Yue suddenly frowned and asked:
"Brother Ming, I discovered that there are neat gaps at regular intervals on this cement road. Is this an unintentional move during road construction, or is it intentional?"
Upon hearing this, Qin Ming turned around and explained to Li Tai with a smile:
"This gap was left intentionally to prevent thermal expansion and contraction from damaging the cement pavement."
Li Tai became even more confused when he heard this, and asked with wide eyes:
"What is thermal expansion and contraction? Why have I never heard of this word before when I read poetry and books?"
When Li Chengqian and others heard this, they also looked at Qin Ming.
Qin Ming then remembered that there was no such theory these days, and looked at the curious eyes of everyone.
The corners of his mouth twitched and he began to explain the principles of thermal expansion and contraction.
"Thermal expansion and contraction refers to a phenomenon. This phenomenon is that everything in the world will grow larger when it is heated and shrink when it is cooled."
"It's just this kind of enlarging and decreasing. Different things become larger and smaller in different proportions. Some are visible to the naked eye, and some are invisible. I call this phenomenon thermal expansion and contraction."
Everyone looked disbelieving when they heard this, and Li Tai was full of doubts.
"How is this possible? According to your statement, doesn't it mean that the palaces and houses are bigger when the weather is hot than when the weather is cold? If this is true, how come the king and the ministers didn't notice it?"
Qin Ming thought for a while and said:
"I have just said that some things are visible as they become larger and smaller, and some are invisible."
Li Chengqian also seemed to be interested, so he interrupted and asked:
"Brother Ming, what is visible? What is invisible?"
Qin Ming had an idea and thought of the floor tiles in the Zhuque Gate, so he smiled and said:
"Of course there are visible ones, such as the floor tiles laid in the palace. Have you ever noticed that the gaps in those floor tiles are larger in winter than in summer?"
"Also at the joints of the fences in the corridor of the main hall, the gaps are also larger in winter than in summer? These are actually phenomena of thermal expansion and contraction."
At this time, Qin Ming saw that several craftsmen in the crowd had thoughtful expressions, so he pointed at them with a smile and said:
"If you don't believe it, you can ask these craftsmen. They have been involved in this kind of work for a long time. They should know it best. Otherwise, why would they deliberately leave gaps when laying floor tiles?"
After hearing this, everyone looked at the craftsmen from the Ministry of Industry, expecting to get answers from them.
Several craftsmen looked at each other, and one of the older, middle-aged craftsmen took a step forward, bowed respectfully to everyone, and said:
"What the man from Qin County said is true. When laying floor tiles or constructing the mortise and tenon structure of the house, I will follow the experience passed down by word of mouth and deliberately leave a gap."
The middle-aged man even looked at Qin Ming with respect as he said this.
"In the past, I only knew that if you didn't do this, the pavement and the tenon joints would be easily damaged, but I didn't know exactly what the cause was. But now I suddenly understand after hearing what the Qin County man said."
After saying that, the middle-aged man walked up to Qin Ming, bowed respectfully and said:
"A great talent from Qin County! I, Zhang Tao, would like to thank the male from Qin County for your guidance."
Seeing this, the other craftsmen quickly bowed to Qin Ming.
Qin Ming smiled and helped the man up, and said with a smile:
"Master Zhang is too praised. You already understand this truth. I just thought of words and explained it."
Duan Lun walked to Qin Ming, patted his shoulder and said with a smile:
"My nephew, please stop being modest! There are many scholars in Chang'an City who have never read my nephew's masterpieces! Especially the short and long poem about Lantern Festival, Thousands of Flowers and Thousands of Trees Blooming on an East Wind Night..."
"What's more, the engraving of your "Three Character Classic" has been completed and printing has begun. It is estimated that in a few months, the entire literary world of the Tang Dynasty will know your name!"
Li Chengqian and Li Tai nodded frequently.
Li Tai even patted Qin Ming on the shoulder and said:
"Brother Ming, you are now the most popular person in Chang'an City. By the way, I will hold a poetry gathering next month. Brother-in-law, you must come then!"
Qin Ming nodded when he heard this.
At this moment, Li Chun pointed to the construction site in front and said:
"Sir, we are here."
After hearing this, everyone looked forward.
.......
noon
Qin Ming finally led a group of people to see the entire construction site, and then led Li Chengqian and others back.
Several craftsmen from the Ministry of Industry wanted to stay at the construction site, so Qin Ming left Li Chun there.
On the way back home, the group even made a special trip to the rice greenhouse.
After entering the greenhouse, Qin Ming immediately saw Yang Zijun and Mao Tu taking notes in the greenhouse.
Yang Zijun was also very happy to see Qin Ming. She smiled and said to Qin Ming:
"Sir, are you back?"
Qin Ming nodded, and then introduced the people around him to Yang Zijun one by one.
Yang Zijun was just stunned for a moment, and then he bowed to everyone in a polite manner.
Li Chengqian and Li Tai were very familiar with the name of this lady of the Yang family.
These days, they often hear sister Changle mention this woman.
Not only is she a math genius, but she is also the concubine of Qin Ming Academy.
They looked at Yang Zijun in front of them, who was wearing a red dress and a veil, with only a pair of pink and phoenix eyes exposed, and couldn't help but sigh in their hearts.
[Sure enough, she is a rare and wonderful woman in the world! It's a pity that the identity is a little different! 】
Li Chengqian cupped his hands and said:
"So you are the Yang family's wife! I often hear the emperor's sister talking about you."
Yang Zijun nodded calmly when he heard this, and then said to Qin Ming:
"Sir, if nothing happens, Maotu and I will go back home first."
Qin Ming nodded when he heard this and said:
"Well, let's go back. Be careful on the way."
Upon hearing this, Yang Zijun took Maotu and left the greenhouse.
After leaving the greenhouse, Maotu said with some doubts:
"Miss, why don't we go back with the young master?"
A hint of sadness flashed through Yang Zijun's eyes, as if she didn't want to dwell on this topic anymore, she said:
"Because someone's stomach is really noisy, and I'm afraid it will affect the young master and them talking about business."
At this moment, there was a gurgling sound from Maotu's stomach.
She chuckled, took Yang Zijun's arm and said:
"Thank you, miss."
