"Whoa......

The rain was pouring down, and it was an hour, but Li Yuanjia was in a good mood.

Because it turns out that as long as they are given enough time and money, Datang's craftsmen can build qualified sewers to withstand the impact of a heavy rainstorm and dozens of large tanks of water. Until now, when he looked out of the window, there was still no water on the ground in the courtyard, and it had all flowed away through several surrounding drains.

So now it's fair to say that those guys did a pretty good job.

Or to put it another way, sewers are technically usable. Next, as long as we think about how to prevent the sewer from clogging, such as setting up some protective fences at the sewer outlets, and issuing some decrees prohibiting the dumping of debris into the sewers, Li Yuanjia believes that this crude but practical sewer system can be built in Luzhou City.

"The only thing that needs to be considered is the cost!"

Looking at the rain curtain falling outside the window, Li Yuanjia began to ponder his three thousand yuan of investment - since he was going to do it, he was ready to do it to the end, using stones to build the sewers of Luzhou City.

But in this way, the cost must have gone up all of a sudden.

Even if 3,000 guan is definitely a lot of money in the eighth year of Zhenguan, and the area of Luzhou City is not large, but it is enough to build the simplest, but the quality is good enough, Li Yuanjia's confidence is really not enough.

So after pondering for a long time, Li Yuanjia turned his head to look at Han Shan, who had been waiting beside him, and asked with a smile: "Old Han, how are our thirteen incense sold recently?" ”

The thirteen incense of five dollars and one tael are exciting to think about!

After trembling twice, Han Shan replied respectfully: "Back to the king, the first batch of thirty catties of thirteen incense sent to Chang'an has been sold, and the total amount of money obtained is more than two thousand yuan, and it has also been sent to the mansion of the Duke of Ying...... The second batch of more than 100 catties has also been sent to Chang'an, but there is no news about how much it has been sold. ”

His face was as silent as possible, but Han Shan's heart was helpless.

Look, look what's going on!

The dignified King of the Tang Dynasty, the history of the Luzhou Thorn, really started this businessman's business, and sent someone to Chang'an with thirteen incense to sell, if the emperor or other ministers knew...... But how did you get it?

"Hmm......"

Of course, Li Yuanjia didn't know what Han Shan was thinking, and even if he knew, he wouldn't care too much, after all, strictly speaking, he couldn't be regarded as doing business, but he just took some thirteen incense and gave it to the father, mother, and uncle in the capital, as well as the second brother who was the emperor and the old man who was the prime minister, but "accidentally" was known by other nobles, so he had to sell it to them.

Thirteen incense is not easy to make, the value is high, you can't let the king give it away, right?

Therefore, Li Yuanjia, who was already prepared, was not afraid of the emperor or other ministers questioning him at all, after all, he did not plan to continue this business for a long time.

It was only after listening to Han Shan's answer that Li Yuanjia's brows furrowed slightly, and he nodded slowly after a while.

I can't help it, I feel a little uncomfortable.

Every time he heard more than 2,000 pounds and more than 100 catties, Li Yuanjia actually wanted to open his mouth and scold Lao Han fiercely. After all, 2,000 has always been more than 2,000, and 2,999 is also more than 2,000, so how much did he send to his uncle? and the number of the second batch of thirteen incense, is it one hundred and one catties or one hundred and ninety-nine catties? According to the price of five or two, that is a difference of several thousand!

If he hadn't known that there were detailed records to look back on, Li Yuanjia would definitely be furious when he heard these words.

Fortunately, this discomfort was quickly put behind, and the next thing was the comfort after making money.

It's so easy to earn.

To be honest, it is not easy to invent the Tang version of the thirteen incense, especially the jade girls, who only know how to bury their heads in the powder and experiment with various spices, and they don't know how to record the experimental data at all. In the end, Li Yuanjia sent someone to them to help record the ratio of various spices in each test, which could be regarded as speeding up the progress. But even so, in the end, it took more than two hundred times to make the thirteen incense that he was barely satisfied with.

Not to mention the labor spent during this period, hundreds of raw materials were used alone.

After all, the spices of this year are so valuable that they can even be used as currency, so even after finding a good ratio, the cost of thirteen spices is more than one hundred dollars and one tael.

But compared with the selling price of five and one tael, this cost is almost negligible.

Under the banner of being produced in Luzhou, it is a perfect match for stir-frying, and Thirteen Spices doesn't need to find anyone to do more publicity, and it was accepted by the bigwigs in Chang'an City at once - everyone knows where the iron pot stir-fry comes from, can you still suspect that King Yu will fool everyone?

What's more, as long as you buy enough 1 pound of thirteen spices at one time, people also come with a recipe for stir-frying, with more than 30 new Cai dishes that have never appeared in Chang'an......

One pound and sixteen taels, only eighty pounds, who can't afford it?

So the thirty catties of thirteen incense were sold out almost instantly, and even the little maid sent by Han Shan to Chang'an was surrounded by many servants in the prince's house, just to buy thirteen incense and that recipe......

In this case, what else is there to say?

The first batch of goods is only 30 catties, one is that this thing is not easy to make, in addition to the spices must be ground finely, but also to strictly control the proportion of each spice to ensure that the taste is consistent; Second, Li Yuanjia is not sure whether this thing will be popular in Chang'an, after all, thirteen spices still have to be used in stir-fry to maximize their effect, and the traditional steaming, boiling and roasting methods are not particularly suitable.

But it is clear that Li Yuanjia underestimated the popularity of iron pot stir-fry in Chang'an.

Although an iron pot blocked ordinary people from the door of stir-frying, and Li Yuanjia only sent it to the palace and his father-in-law a few times, what he didn't expect was that the enthusiasm of the nobles of the Tang Dynasty for stir-fry was obviously beyond imagination - there were more than 30 stir-fry recipes leaked from Fang Xuanling's mansion alone!

The bigwigs who got the recipes, who don't have a few friends and relatives or something? So in just one year, the princes in Chang'an City basically have iron pots in their mansions, and the cooks at home will at least fry a few simple side dishes.

And even if the chef at home has not mastered the art of stir-frying, when they hear that the novelty spices from Luzhou are very suitable for stir-frying, who would mind saving some for later? What's more, there are recipes to give, so there's nothing to hesitate about.

It's only one or two dollars for five yuan, and the nobles of the Tang Dynasty don't blink their eyes when they buy thirteen incense.

In just half a day's effort, after the news spread, thirty catties of thirteen incense became more than 1,000 yuan, and was secretly sent to Li Yuanjia's maternal uncle Yu Wenshi and his family......

Well, that's a long way off.

In short, after a simple calculation, Li Yuanjia had to sigh secretly.

In the future, the money to build a 100-meter sewer, if you want to buy thirteen incense, why not buy a car? But in this era, he only needs to pull a cart of thirteen incense to Chang'an or Luoyang to sell it, not to mention the money he earns, not to mention building the sewer system of Luzhou City, I am afraid that it is to build the sewer system of the counties and counties under Luzhou, and the problem is not big, right?

So after thinking about it, Li Yuanjia quickly continued: "Old Han, let Yu Niang and them work harder during this time, and make as many thirteen incense as they can!" Within three months, as much as you make, you will send it to Chang'an......"
