Li Yuan and Li Tai quickly walked to the four-wheel transport truck and walked back and forth around the transport truck several times.
Qin Ming adopted the trailer design of later generations for this four-wheeled transport vehicle. The four wheels were not equipped with carriages, but with a trailer specially used to carry goods.
Compared with later generations of trucks, apart from the fact that they were mostly made of wood and powered by horses, the difference in style was not particularly big.
Of course, the difference here is not big, that’s what Qin Ming thinks!
Li Yuan stroked his gray beard and said with some disappointment:
"Four wheels? Someone has thought about making a carriage like this before. Although it can indeed carry a lot of cargo, it will make the carriage difficult to turn."
After speaking, Li Yuan patted Qin Ming's shoulder and comforted him:
"But the style of your carriage is quite novel. As long as the carriage of the original carriage is changed like this, it might be able to carry a lot of goods."
Qin Ming smiled at Li Yuan.
"Grandpa, would you believe me if I said that I have solved the steering problem of the carriage?"
Li Yuan was stunned when he heard this and turned to the problem. Is the problem solved? How is this possible?
In order to quickly transport food and grass to the counter-rebellion army, the Ministry of Industry also proposed the idea of building four-wheeled carriages to improve transportation capacity.
But as a result, hundreds of craftsmen gathered together and failed to solve the steering problem of the four-wheeled carriage for days and nights, and finally had to give up.
Now this kid in front of me actually said that he solved the steering problem of the four-wheel carriage?
Such an understatement?
"Brother Ming, do you know what you are talking about?"
Qin Ming smiled and nodded, and then said to Zhang Fangzhu beside him:
"Rokuro, please ask someone to drive it, just to test whether this carriage is up to standard."
Zhang Liulang bowed and said:
"Yes, sir."
After speaking, Zhang Liulang walked up to a strong man and whispered a few words. As he spoke, he stretched out his hand to point to Qin and Ming.
After hearing this, the strong man bowed his hands to Qin Ming and others, then walked to the carriage and jumped on it easily.
"Sir, please stand a little further away. The younger one has to drive."
When Qin Ming heard this, he quickly pulled Li Yuan and Li Tai to stand under the eaves.
After a while.
Li Yuan looked excitedly and took Qin Ming's hand and asked:
"Amazing! Amazing! Brother Ming, how did you do it? If the court uses such a carriage to transport grain and grass, it will be twice the result with half the effort!"
In fact, Qin Ming had drafted the design of the four-wheeled carriage last year. After all, the two-wheeled carriage running on the official road was too bumpy.
Just because he didn't go to Chang'an many times in the past, Qin Ming never put the building of a four-wheeled carriage on his agenda.
A few days ago, after he came up with the idea of building an engineering vehicle, he immediately told Li Chun in detail how to solve the steering problem of the four-wheel carriage.
Later, after repeated verification by Li Chunhe and craftsmen from the Institute of Engineering, this four-wheel transport vehicle was finally built.
After briefly explaining the steering principle of the four-wheeled vehicle with Li Yuan and Li Tai.
Qin Ming smiled and said to Li Yuan:
"Grandpa, after I have built dozens of transport vehicles in my house, I will have someone build a four-wheeled carriage specifically for you, so that your rides will not be as bumpy as before."
Li Yuan felt warm after hearing this, took Qin Ming's hand, and gently patted the back of Qin Ming's hand with his right hand.
"Okay, okay, okay, my dear grandson is ready."
After hearing Qin Ming's words, Li Tai's eyes lit up, he looked at Qin Ming eagerly and said:
"Brother Ming, how about building one for me when the time comes? I am willing to buy it from you at a high price."
Li Yuan reached out and gave Li Tai a big bag.
"At such a young age, they are greedy for enjoyment. Have the royal heirs become corrupted to this extent?"
"In this case, as a member of the Li family in Longxi, I must go to Zongzheng Temple when I have time."
Li Tai broke into a cold sweat when he heard this. He had really lost his mind just now.
How could he say such a thing in front of his grandfather? If he really had to go to Zongzheng Temple for this, or even mention it to his father.
I have to shed my skin even if I don’t die!
Thinking of this, Li Tai quickly bowed and begged for mercy:
"Tai knows he was wrong, and I ask my grandfather to forgive Tai this time."
Qin Ming looked at the old man and the young man speechlessly, thinking that he must not let these two people get together again next time.
He tugged on Li Yuan's sleeve and changed the topic:
"Grandpa, what I just showed you is a truck. There is a yard next to it that is specially built for road rollers. Can I take you to see it?"
Li Yuan said doubtfully:
"Road roller? What is it for?"
Qin Ming explained:
"The road roller is specially used to compact the road surface. With it, there is no need for manpower to compact the road surface."
"Oh? Is it so magical? Take grandpa to see it."
Qin Ming stretched out his arm to signal Li Yuan to go to the east yard.
"Grandpa, please come this way."
Li Yuan nodded slightly, and then walked towards the side yard first.
Qin Ming pulled Li Tai, who was standing there dumbly.
"Artai, why are you standing there in such a daze? Why don't you hurry up and catch up?"
"Oh, okay, okay."
.......
Qin Ming took Li Yuan to visit the car-making workshop for an hour before returning to the Qin Mansion.
As the second-in-command of the Roads and Bridges Department, Li Tai will preside over the groundbreaking ceremony for Chang'an City tomorrow together with the third-in-command Ma Zhou.
So after Li Tai left the workshop, he took his followers and left.
After Qin Ming sent Li Yuan back to the small courtyard, he rested for a while in the study and then asked the maid to find Yang Zijun and Mao Tu.
The weather has been getting warmer and warmer recently. Unconsciously, people in the backyard gradually changed out of their thick down jackets and put on underskirts.
Today, Yang Zijun was wearing a bright red long-sleeved fairy dress and a cloak embroidered with plum blossoms, and her whole person was full of fairy spirit.
So when Yang Zijun appeared in front of Qin Ming, wearing a gold walking stick on his head and veil covering his face, Qin Ming was stunned for a moment.
It's just that Yang Zijun's outfit is so good-looking, as if she came out of a comic.
"Zijun, weren't you still wearing your down jacket this morning? Why did you change your makeup now?"
Yang Zijun's face turned red when she heard this. Of course she dressed up deliberately to go to the greenhouse with Qin Ming to see the rice.
Just when she was about to say what she had planned for a long time.
Maotu, who was wearing a skirt next to him, said with a smile:
"Sir, isn't my lady very beautiful dressed up like this? She is dressed up... ah!"
Yang Zijun's little feet under her skirt stepped on Mao Tu's instep and glared at Mao Tu.
"Maotu, don't talk nonsense."
When Maotu heard this, he was about to open his mouth to refute, but his foot hurt again, and his little head immediately drooped.
Yang Zijun then turned his head and said to Qin Ming with a red face:
"Sir, don't listen to Mao Tu's nonsense. I just thought it was hot in the greenhouse, so I changed my clothes like this."
Qin Ming suddenly realized what he said.
I see!
