After circling Li Yuanjia's carriage several times, Li Shimin's heart was filled with curiosity.
When Li Shimin found out that Lao Shiyi was riding in a carriage all the way, he felt a little unhappy.
However, he also knew that the boy hardly went out on weekdays and his riding skills were quite poor, so he didn't plan to ask anything at first, but then he heard that the carriage Li Yuanjia was riding in was very weird, with four wheels speeding along the road.
It could also be easily controlled, which made the emperor feel a little curious.
There are always good things in Prince Han's Mansion, and he knows this very well.
And more importantly, Li Shimin knew that although his younger brother was low-key, his words never contained any moisture. So for him to say that two-wheeled carriages will become extinct in the future, I am afraid that the four-wheeled carriage in front of him
It really has an amazing secret!
From ancient times to the present, everyone has been using two-wheeled carriages, but this does not mean that four-wheeled carriages have never been built. It is just that it is large and bulky, and secondly, the steering problem is always difficult to solve.
So no one is interested.
But Li Yuanjia’s carriage seems to have been solved?
After circling the carriage a few times, Li Shimin did not ask about the things that made him feel new, but looked at Li Yuanjia first: "Eleventh Man, take me up and have a look!
"Okay, second brother."
Seeing that he seemed to be in a good mood, Li Yuanjia did not call him "Your Majesty" and directly used the title "Second Brother".
Without further ado, Li Yuanjia took the emperor directly onto the carriage, opened the curtain and got in.
As soon as he entered, Li Shimin narrowed his eyes and was quite surprised that the space inside the carriage was larger than he imagined. It was not crowded at all for two people to stay in it, and...
"This...you actually prepared bedding in the carriage?"
Sitting in the carriage, patting the quilt under his buttocks, Li Shimin looked weird and said with a smile: "Others participate in winter hunting by riding horses, and are exposed to wind and sun along the way, but you will enjoy it...
The wind can't blow, and it's much warmer than outside, so you'll suffer a lot less pain along the way!"
He never imagined that Li Yuanjia would make a carriage compartment look like a small bedroom, with thick mattresses and a thick quilt on top! In addition, there were thick curtains hanging around it.
, making the car much warmer than outside, and Li Er felt the warmth as soon as he entered.
So after being surprised, Li Shimin became even more unhappy!
I was riding a horse out in the cold, but how could you, half-lying on such a comfortable carriage?
This is simply unreasonable!
Of course, Li Yuanjia also noticed the change in the expression on the second child's face, and with a sudden thought, he quickly said: "Second brother, I'm not just riding this carriage specifically for enjoyment!"
He knew that Li Shimin was not easy to fool, and he did not dare to deny that he wanted to enjoy himself.
So after hearing this answer, the emperor raised his eyebrows and said with a strange smile: "Oh? Then tell me, why did you take out this carriage this time?"
"Well..."
After solemnly pondering, Li Yuanjia said seriously: "Second brother, I originally asked people to make this carriage because it would be of great use if it was done! If used properly, it can bring a lot of benefits to the Tang Dynasty.
Woolen cloth!"
Regarding what he said, Li Shimin did not comment. He just smiled and then asked: "Okay, tell me, what are the benefits of this carriage?"
"First of all, of course it is more comfortable to ride."
Patting the wall of the carriage, Li Yuanjia smiled and said: "Because of the four wheels, the carriage can be made larger, which makes it more spacious inside and more comfortable to ride... Of course,
The larger the carriage becomes, the heavier it becomes, so this carriage requires at least two horses to pull it. If you want to run faster, you can use four key horses at once like my brother..."
When he said this, Li Yuanjia couldn't help but feel happy about his identity again.
The emperor drives six, so as a prince he would definitely not dare to use six horses, but there is no problem at all with four horses. If an ordinary citizen dares to use four horses at a time, he will probably be punished.
.
After listening to Li Yuanjia's words, the emperor nodded.
This point was right in front of him. He could understand it just by looking at it. It was easy to understand, so Li Shimin raised his eyebrows and said, "What else? Go on!"
If that were the case, the emperor's interest would not be very great.
For Li Shimin, nothing is as convenient as riding a horse. Even if he needs to ride a carriage, it will only be for a short time and a short distance. There is no point in riding more comfortably.
"Another benefit is, of course, the load capacity."
Taking a deep breath, Li Yuanjia's expression became serious: "Second brother, with this four-wheeled carriage, it can not only carry people, but also transport goods! I have tried it before,
If it is used to load cargo, this carriage can hold at least 400 kilograms of cargo, and there is no problem at all pulling it with two horses! If it can be improved better in the future, maybe it can pull more!"
As he said this, Li Yuanjia was certain in his heart that the improved carriage would be able to pull more!
"Oh? Four hundred pounds?"
After hearing what he said, the emperor finally became a little interested.
From ancient times to the present, transportation has always been a major problem for the imperial court, especially for the Tang Dynasty. The lack of food in the north has almost become a worry for the emperors. Even with the Grand Canal built by the former Sui Yang Emperor at the expense of the world,
It can only ensure that food is delivered to Luoyang. It is still difficult to supply Chang'an, a huge city.
Therefore, every few years, the emperors would take the Tang Dynasty Central Committee to Luoyang and stay there for a year and a half, in order to relieve Chang'an's food supply pressure.
So when he heard that this carriage could pull four hundred kilograms of goods, Li Shimin naturally became interested.
However, after seeing the slight change in expression on his face, Li Yuanjia felt a little panicked and coughed twice quickly: "Ahem, but... Second brother, although this four-wheeled carriage is good, it needs to be like what I just said.
In this way, the theory that two-wheeled carriages will become extinct in the future may not be realized for the time being."
"Oh? What do you mean?"
After listening to Li Yuanjia's words, the emperor immediately frowned and glared at him with dissatisfaction.
Li Shimin would naturally be very unhappy when a bucket of cold water was poured on him just after he had gained some interest.
But no matter how unhappy he was, Li Yuanjia didn't dare to let him misunderstand that this kind of four-wheeled carriage could be promoted on a large scale and solve the current transportation problems. In that case... not just in case, but definitely not possible, wouldn't it be
The crime of deceiving the emperor?
So after pondering for a moment, Li Yuanjia said seriously: "Second brother, although this four-wheeled carriage is good, it has too many restrictions on its use. Moreover, it takes as much time to make one as it would to make ten ordinary carriages."
