When the Lin family's caravan, which had placed Lin Sen's ardent expectations, left the Lin family's Zhuangzi and went to join the Cheng family's caravan and several of their caravans, including the second steward of the Cheng family, they were very envious of the Lin family's sub-villagers, although they didn't take into account the strategic significance of this four-wheeled carriage, but this benefit was also really visible.

They all transported about the same total number of goods, and the escorts were all about the same, but the difficulty of guarding these hundred carriages that could not run fast and twenty or thirty carriages that ran fast must be very different.

When a robber is encountered, the measures that can be taken will be very different, especially when these twenty or thirty carriages can still be used as mobile fortresses, the mood of the guards will be very different.

When the people of the royal caravan saw it, their first reaction was to quickly run to report to Emperor Li Shimin that such a miraculous means of transport had appeared.

Soon after, Lin Sen, who was confused, was called into the palace before the rugby game began, and he thought that the emperor had something to ask about rugby.

After going through the entire schedule in his mind and confirming that there were no mistakes, Lin Sen ran to Li Shimin with confidence.

After Li Shimin said that he would go to watch the final of the rugby game in person, news immediately came from the Five Cities Terracotta Division, saying that he would provide strong support throughout the game and would definitely work hard to mobilize manpower to help maintain order on the scene.

They have a lot of experience in this kind of thing, and they have participated in all the large-scale events, and they are still very trustworthy.

In addition, those second-generation families will also arrange for people to come to help, so Lin Sen is more relieved about the situation over there.

It was only after entering the palace that Lin Sen realized that he had thought about it, although Li Shimin also had a good impression of this rugby, but it was not to the point of making a special trip to inquire about it.

"I heard that you kid made another four-wheeled carriage? Can you transport many things at once, which can be several times higher than the existing carriage? And it's very flexible to turn! Li Shimin still asked with some disbelief.

Although the people who knew the royal caravan would never dare to lie to him, wasn't that asking for their own death, and they also knew that Lin Sen could always have many wonderful ideas, but it was still difficult to believe this kind of thing until he saw the real thing.

After all, the transportation capacity is increased several times at a time, and in Li Shimin's eyes, such a thing is a militaristic weapon, and with this thing, it can strengthen a lot of ties with the border areas.

If it is used to transport military materials, it will save a lot, because the biggest loss of grain and grass in this year is that people eat horses during transportation, and with the increase of distance, this proportion will rise sharply.

But if it is replaced by a four-wheeled carriage, and several times more grain and grass are transported at a time, there will be fewer people and horses needed, and the number of people who can be delivered to the destination will be much more, and this benefit can be said to be immediate. It would be ideal if it could be as fast as it was reported below.

"The last general did get a four-wheeled carriage out, if Your Majesty doesn't believe it, you can send someone to the Cheng family's mansion and let someone bring the carriage of Huaiyu Niangzi, Your Majesty will know it when you see it." Lin Sen replied affirmatively.

With such a good thing, Lin Sen naturally will not forget his wife. The girl often rides a horse not very elegant, not to mention, and it is easy to deform the two legs into Luo hoop legs, which doesn't look beautiful.

Although Cheng Huaiyu can also ride a horse, he is not proficient. If you really want to go to the Lin family's Zhuangzi to find Lin Sen by yourself, you have to take the bumpy two-wheeled carriage.

Now that the four-wheeled carriage has come, Lin Sen naturally has to get a beautiful and small one for her to use, running fast and steady, and Lin Sen of the province continues to feel sorry for his wife.

"No wonder it's said everywhere in Chang'an City now that your kid is a virtuous ......man," Li Shimin pointed at Lin Sen and said with a smile.

"I just cherish her." Lin Sen didn't look embarrassed at all, we are just a family of beloved wives, I'm proud!

"Okay, okay, I know that you are rare and jade, and she can be regarded as a wise and wise man." Li Shimin can't do anything about Lin Sen.

"But you kid don't have to be polite, bring the trick of this four-wheeled carriage, for you this may be just a whim plaything, but in my opinion, this is a rare militaristic weapon!

In the future, there will be a few more official roads leading to the border city, and it will be much more convenient to transport grain and grass. Li Shimin really didn't see Lin Sen, so he directly asked for something.

"Yes, when the time comes, get more prisoners of war on the grassland back, and build the straight road leading to several major gateways in Chang'an City, once there is a change, whether it is grain and grass or soldiers and horses, it can come in an instant, and ensure that those aliens who belong to the Tang Dynasty will not be able to jump." Lin Sen said with a smile, he was also happy to see that kind of situation.

The official road of Datang at this time was equivalent to the national highway of later generations, and the straight road and highway were things of the same nature, and they were all busy routes that undertook the most important traffic tasks.

"Oh, by the way, I'll send you the design of the carriage right away, and I'll finish it now. Hey. Lin Sen thought for a while, and then remembered that Li Shimin was still waiting to ask for something, and said a little curtly.

"Okay, you can draw it. Don't worry, I won't treat you badly, and when Shuofang's army returns, I may be able to surprise you. Li Shimin patted Lin Sen's shoulder with satisfaction and said with a smile.

Lin Sen's joy when he contributed things was also something he was quite satisfied with. Of course, this subordinate is so happy, unlike those people in the family, some good things are always hidden, if he, the emperor, doesn't give more benefits, he will feel a little embarrassed, and it will also cool other people's hearts.

It's just that since you're close to this kid, there's nothing bad about hanging his appetite.

"That kid is just waiting." Lin Sen replied with a smile, and ran to draw the schematic diagram of the structure of the four-wheeled carriage, and the universal joint-like structure was the most important.

He is absolutely trustworthy of Li Shimin's promise, this is not a stingy master, otherwise he would not have taken things out so happily.

What's more, this thing is already a militaristic weapon recognized by Li Shimin himself, and the reward given is poor, and Li Shimin doesn't look good on his own face.

"Alright, you kid can go." Li Shimin couldn't see Lin Sen's snort, and after seeing that the drawings were drawn, he waved his hand and motioned to Lin Sen to get out of the way like flies.

When Lin Sen happily turned around and left, Li Shimin couldn't help but smile at Lin Sen's back.

Lin Sen came and went in a hurry, but he didn't have any nostalgia at all. The rugby game was about to start, and although he didn't need to continue to do it himself, he couldn't help but want to check the situation.

And not long after he left, Cheng Huaiyu's four-wheeled carriage was also sent into the palace.

Li Shimin easily confirmed those information, and became more and more sure of his judgment on this thing, this is indeed a militaristic weapon, it seems that the reward given to Lin Sen has to be mentioned again.
