Although now with the stabilization of the forces, the output of Bupengpeng's small blast furnace has also stabilized, and there can be as much as 2,000 catties of iron at a time.

Now more than a dozen small blast furnaces have been built, and the iron tools produced have gradually begun to equip the whole army on a large scale. But Liu Shengzhi did not plan to export.

That's a capital enemy!

I always see some stupid shortcomings, saying that they ran to ancient times, relying on technological upgrades, to make money from the ancients, and dared to sell anything.

But I don't want to think about it, under such ancient conditions, unless your golden finger is bigger than the sky. Otherwise, under such conditions, there will always be limits to technological progress.

There is always a bottleneck in the speed of technological progress.

It's like in modern time and space, when some developed countries thought that the speed of technological progress could expand indefinitely.

As a result, self-abandonment of martial arts, not playing with low value-added industries, expecting the financial tertiary industry, or even high-tech, to become the top of the global financial chain, and finally got rid of the tragedy......

That was, of course, decades ago. In Liu Shengzhi's era, the signs of a new round of scientific and technological explosion have reappeared.

"So, can I get some bronze ......?" asked Shi tentatively.

But recently, copper coins have been banned in all parts of Hanzhong. In its place, it was a new kind of money.

"No, copper and iron are strategic materials. But if you need salt, you can be accommodating......"

In ancient times, salt was also an extremely important strategic material. The so-called ban on salt and iron.

Together with tea and porcelain, textiles were almost the most important commodities in ancient Middle-earth trade.

"Salt?" Shi Bei looked like a smile. This Hanzhong is not a salt-producing land.

Moreover, there is no shortage of salt in the Western Regions. At most, you can only buy it in Guanzhong. However, the mountains and rivers between the two places are dangerous. Shipping costs are extremely high. But how can it be compared to Hedong salt?

"Actually, here in my Hanzhong, there is still a treasure. Someone's coming. Tea and ......"

Someone brought a plate of yellowed crystal things and motioned for Shi Bei to taste it.

"This is Shi Mi ......" took out one, tasted it, this Shi Bei's eyes lit up, and he shouted: "Isn't this the West Pole Shimi produced in Tianzhu, why is there a ...... here?"

Shi Bei was excited, the price of this thing was extremely high. It can only come from the distant West Tianzhu, no matter how cheap it is, after a difficult long-distance transportation. The prices are also incredibly expensive.

It is the same volume of gold that can be exchanged for the same volume of stone honey.

Liu Shengzhi smiled and was silent, and there is no modern person like Liu Shengzhi who knows the importance of trade better.

Therefore, Liu Shengzhi has been thinking about how to expand trade and make money very early.

It's just that in such an era, trade is still at a very low level. It is only the rare and exotic products from all over the world that can best attract merchants and bring a lot of income.

And the porcelain tea leaves above have not yet been born in this era. Although Shu brocade is good. It is not owned by Hanzhong alone. As for salt, it is not from Hanzhong......

So thinking about coming and going, Liu Shengzhi sacrificed two kinds of big killing weapons.

This so-called stone honey is actually rock sugar. It's just a bad white sugar. Naturally, sugar cane juice is used to refine it.

Simply yes. In this era, a small amount of sugarcane was planted in Hanzhong. Liu Shengzhi came up with this idea.

It's just that this thing doesn't grow very well in Hanzhong in this era. There seems to be something wrong with the variety, but it is small and thin.

I'm afraid it's not possible to manufacture it in large quantities. But it's enough as a luxury!

"How much is this, I want it all. "Don't rejoice. Even if such a thing is transported to Guanzhong, it can be easily sold for a sky-high price. If it is shipped to the Western Regions, the price will not be higher......

"Don't be in a hurry, don't ......be in a hurry," Liu Shengzhi smiled: "Let's look at something better!"

This so-called stone honey is just an appetizer. The real big killer is about to be sacrificed!

Soon someone took out a tea brick and put it in front of Na Shibei.

is so swarthy, it seems to be mixed with a lot of sundries, and the poorly fired bricks suddenly make Shi Bei like the second monk scratch his head!

However, seeing Liu Shengzhi smiling like this, coming out with this thing, he was obviously extremely confident. This Shi Bei doesn't dare to slack off, but he is also a well-informed person. I recognized it for a long time, but I couldn't recognize what it was.

"This thing is called tea," Liu Sheng waved his hand.

Two guards came up, smashed the tea bricks, and began to boil them in the water.

In a moment, a strange fragrance wafted out.

"What is this?"

"Please," Liu Shengzhi stretched out his hand and smiled, gently tasting the tea in front of him. The taste is strange, so that Liu Shengzhi, who is used to drinking the tongue of tea in later generations, is not used to drinking this thing at all.

"Is this a medicinal soup?" just took a sip, and Shi Bei had already called out stupidly. Why didn't I expect that Liu Shengzhi's solemn introduction was actually a medicinal soup.

"Medicinal soup? Liu Shengzhi said with a smile.

Then let his subordinates put in seasonings, such as salt, orange peel, ginger and garlic, and put them in the same boil. Please taste this history again.

That Shi Bei smacked his lips, and this was the only way to drink a little bit of taste.

Liu Shengzhi laughed again, and asked people to add stone honey, milk and other things to it. It is cooked in a moment, and the aroma is overflowing.

Drinking it again this time is very in line with the taste of this history, which makes his eyes light up and vaguely realize something.

"The most important thing about this thing is not here, but that it can heal diseases, and that it can eliminate food and relieve greasy...... The herdsmen on the grassland eat meat and drink milk all day long, and they are greasy and gathered, so they have a short life. And if you can drink tea every day......"

"Hiss......" Speaking of this, this Shi Bei suddenly came to his senses. If it is really like Liu Shengzhi said, how precious this thing should be, then you don't need to ask!

In fact, since the Tang Dynasty, the most important weapon of the Central Plains Dynasty for the nomads was this thing.

The grassland herdsmen of later generations are even more indispensable for tea. Just as Liu Shengzhi said, those herdsmen don't eat any vegetables, rice and noodles all year round, all dairy products and meat. But it is precisely the tea that depends on the solution......

Therefore, after the Song Dynasty, this thing almost became a strategic resource. A hand around the necks of those nomads. The importance is self-evident.

It's just that in this era, this tea is still rarely popular. It will also be in Jiangzuo, slowly becoming popular. In the future, during the Northern and Southern Dynasties, the fugitives of the Southern Dynasties gradually brought the habit of drinking tea to the north, and even left interesting stories such as tea nightmares.

The real large-scale popularization will be after the Lu Yu tea in the Tang Dynasty...... (To be continued......)
