Under the willow tree, Xiao Han was foaming at the foam, and what he said was called an oath.

And Chai Shao and a few people also listened to the drooling, and the whole person was almost stupid!

The water hammer with the strength of a thousand pounds, the craftsman with arms thicker than the thighs, and all kinds of magical quenching materials.

These things that they had never heard of before stimulated their curiosity so much that they didn't even notice the dog's face over there, and they were all twitching incessantly......

All right.

As a participant and opinion provider throughout the process.

The dog also knows that this rhubarb crossbow, which can be called the strongest today, is indeed not easy to come by!

However, that's not as evil as Hou Ye said, right?

What does it mean that a jack of water hammer was specially built in order to build it?

Wasn't that thing in the plan? It seems that if there is no such rhubarb crossbow, those red-eyed craftsmen will build it, right?!

Also, the new steelmaking technology of Narausch!

The dog admits that this is indeed a step-by-step experiment, and more than tens of millions of materials have been wasted for this.

But it seems that the final result is not just the use of the rhubarb crossbow, right? Haven't you seen more and more finished steel products sold in Sanyuan County now? It's the result of those experiments!

If it were true, relying on those things alone, this cost would have been recouped a long time ago!

And not only that, but the dog also knows:

The price of the latest four-wheeled carriages in Sanyuan County alone was enough for those craftsmen to experiment hundreds of times.

Speaking of this four-wheeled carriage, the dog had to be amazed by Hou Ye's genius idea again.

Just in everybody gets used to it.

I even thought that the carriage should have two wheels!

But his own Hou Ye drew a sketch and threw it to Lao Cao, asking him to find a way to make the things on the picture.

Lao Cao will not question Xiao Han's thoughts! may have questioned it before, but countless facts have proved that no matter how outrageous the idea of the self-marquis is! In the end, he will definitely prove right!

The four-wheeled carriage is actually not very technical, and the reason why it was not there before is because the shock absorption problem has not been solved.

After all, two wheels can turn people's food upside down, let alone two more wheels!

There are two more places to transmit earthquakes, and it's strange that they are heavier!

The problem of shock absorption is nothing, with a new spring steel plate to load the carriage, the vibration can be reduced by seventy!

If you wrap a thick layer of rhinoceros leather on the wheel at any cost, it will not be much different from the cars of later generations.

Of course, in addition to shock absorption, there is another problem with the four-wheeled carriage, and that is steering.

It's effortless and fast to run in one direction with four wheels, but if you have to turn a corner, it's over!

After the advent of the first four-wheeled carriage that could only walk straight, Xiao Han immediately discovered this fatal shortcoming.

However, having seen universal wheels, he quickly came up with a solution, that is, to change the first axle and the carriage from fixed to rotary.

In this way, the two wheels in the first row can turn freely with the horses pulling the cart in front.

When all the problems were fixed, the first new four-wheeled carriage was introduced, which immediately attracted a large crowd of onlookers.

For the first time in his life, the well-informed Chang'an people saw such a carriage:

The carriage made of birch is carved with silver inlays, and four large wheels are neatly arranged under the carriage, and two horses are drawn in front.

Running up, the mountain road is like walking on the ground, walking hundreds of miles, as steady as an old dog... Ahem, steady as Mount Tai!

How much does such a carriage have to sell for?

Steward Lu pondered how to get a hundred times, after all, a good war horse is still worth the money!

As a result, Xiao Han made a decision directly, with a minimum of 1,000 yuan, and there was no bargaining!

In his words: What Sanyuan County sells is never a commodity, but a noble life!

Thousands of copper coins, just buy a carriage?

As soon as this price came out, the vast majority of people who watched the excitement thought that the people of Mihara Prefecture were crazy!

Just when they were waiting to see the people of Sanyuan County, the last one could not be sold, and finally went home in disgrace.

Secretly, Steward Lu has already received a stack of orders.

And in these orders, you can't see the cheapest kind at all, and almost everyone indicates the most expensive!

"Dog, dog?! Why are you still stunned? Go back and look at Lao Tzu's gold, uh, no, it's Lao Tzu's big yellow crossbow! ”

Just when the dog's thoughts drifted to Sanyuan County, Cheng Biting Jin's sudden voice instantly pulled him back to reality.

"Your rhubarb?"

The dog full of money and carriage hadn't reacted yet, and just about to ask, he saw Cheng biting Jin blowing his beard and glaring and said:

"Nonsense! You're on an errand under me, so don't you just take care of this thing? Such a precious thing, if I accidentally bump into it, your lord asks me for money, where can I raise money for him? Sell yourself to pay off your debts? ”

Cheng bit Jin Zheng said confidently, but Xiao Han next to him suddenly followed in a weird way: "No, no, no, it's worthless for you to sell yourself, even if it is at the market price, you can't sell it for a pound of thirty wen......"

"What's a pound and thirty Wen?"

Cheng Yanjin didn't react at first, wait for a closer look!

Thirty essays? Isn't that the price of pork?

"Wow, good boy, you scolded me Lao Cheng for being a pig!" Cheng Yanjin's beard stood up, and he glared at Xiao Han angrily.

Xiao Han suddenly felt that he seemed to have overestimated his strength value, and hurriedly retreated to the side: "No, really not!" Ah......h

But soon, someone's screams echoed in the sky above Luokou City, and they couldn't disperse for a long time......

Chang'an City, Sanyuan County.

Xue Pan was leaning lazily on the chair at this time, casually looking at the account books in front of her, and now she rarely went back to her home in Chang'an.

More often, he is in the Xiao Mansion, quietly watching the huge sums of money gathered here like a stream.

"Miss, it's too hot today, shall we go get some ice?" Xiao Ai was on the side, complaining while shaking the fan for Xue Pan.

The ice cubes that had been brought in in the morning were now only a few ice slags, and the house was once again hot in the summer.

Xue Pan frowned, put down the account book and said, "No, Xiao Han said, ice cubes can't be used for heat dissipation!" It's easy to get excited to the body, and when you get old, you'll suffer! ”

When Xiao Ai heard that he couldn't take ice cubes, his mouth immediately pouted, and he twisted his hands and said, "Then how about I go and get a pot of crispy mountains and come back to eat?" I just saw that there are dried fruits on the crispy mountain made by Xiao Eleven, you will definitely like to eat it! ”

"Hehe, do I like to eat, or do you like to eat?" Xiao Ai's little ghost thoughts, Xue Pan naturally knew it, and asked rhetorically with a smile.

When her mind was pierced, Xiao Ai immediately blushed, stomped her feet on the ground and said, "Naturally, you like to eat, I... I'll just take a look! ”

Looking at Xiao Ai, who was angry and ashamed, Xue Pan couldn't help but smile and nodded: "Then, this is what you said!" Go get a crispy mountain, I'll eat it, you look at ......"

Xiao Ai's eyes widened, and she grabbed Xue Pan's shoulder and shook it: "Miss~"

Xue Pan couldn't stand this, was shaken a few times, and hurriedly said: "Okay, okay, don't shake it, give it to you!" I'll give you a total meal! ”

Xiao Ai was finally happy now, and tidied up Xue Pan's wrinkled clothes: "Hehe, Miss is the best!" The best person in the world! I'm going to get you some delicious food! ”

Seeing Xiao Ai happily jumping out of the room, Xue Pan shook his head and let out a sigh of relief.

This stupid girl, now that she is so old, she still knows how to eat and play, and she never thinks about the future.

"Hey...... I don't know if Xiao Han is hot in such a distant place, and whether it is dangerous. ”
