The exchange lasted for five days, and both the Liangzhou government and the Shaodangqiang government achieved relatively satisfactory results.

Judging from the results, the most purchased by the Burning Dangqiang side is Liangzhou fine salt.

In addition to the 3,000 catties of fine salt that the two parties agreed to give away for free, they also bought a larger amount of fine salt, and they bought a large amount of fine salt themselves, as if they were afraid that they would not have enough to eat in the future, and they hated to buy out the current inventory of the entire Liangzhou Prefecture.

On the other hand, the Liangzhou government bought a large number of live livestock, especially horses of good quality, and the Liangzhou government also bought a lot to make up for the government's demand for horses.

Exchanging salt for horses has also become a tacit understanding between the Liangzhou government and Dangqiang.

During the mutual market transaction, everyone adheres to the principle of mutual benefit, discounts the purchase of bulk commodities to a certain extent, and gives each other a step, gives some face, and accumulates a little human relationship, which may come in handy in the future.

After the first mutual market was a complete success, Liu Bei had a drink with several leading figures of Dangqiang.

Everyone gathered around to eat a meal of roast mutton, talking and laughing, Liu Bei also used a few words of Qiang he had just learned to say a few words to them, which made these people very surprised.

In the end, the two sides agreed that such a mutual market would be carried out twice a year, and if there was any temporary demand, Naduo and Liu Bei would contact directly, and the two sides would directly connect with each other at the highest level, so as to solve the problem in the fastest and most convenient way, saving many incidents.

This mutual market is considered to be the end of victory.

Liu Bei fulfilled his promise, and Burning Dangqiang also fulfilled their promise, and the two sides had a very pleasant cooperation, and the subsequent cooperation must be carried out.

After the matter of Jincheng County was completed, Liu Bei went directly to Wuwei County to inspect the restarted mining work on the new coal mine site in Wuwei County, and was satisfied with the new management model.

The new manager of the coal mine workshop was Chen Jun, a member of the former secretary department of the Ministry of General Affairs, who, at Liu Bei's request, set a daily working limit, a rest period, a rule for three meals a day, and a monthly salary for the miners.

Compared with when I was a slave before, the treatment of a worker now is simply one day and the next.

Liu Bei liquidated the county government officials after his predecessor Wuwei Taishou ran away, strictly investigated their past behavior, found that two-thirds of them had committed illegal and criminal acts, and punished all of them.

The officials who were directly involved in the previous miners' incident were seriously questioned, and the two main responsible officials were killed, and thirteen murderers were also killed.

The grievances of the local people after being suppressed by the government were also pacified after the government compensated and liquidated the criminal officials and servants - there is no way to do it if it is not calm, the government has given a rare explanation, and it has given some compensation for the first time, and if you don't go to work, there will be no surplus food at home.

Experienced miners quickly returned to work and restarted the mining work that had been delayed for a long time.

Truckloads of coal were transported to the coal mill for processing, and at Liu Bei's request, the original pressed coal cake was drilled into a state of honeycomb coal, and then transported to the place where it was needed for use.

Most of the raw materials for boiling salt and iron smelting are locally mined coal, which reduces fuel costs.

In terms of iron smelting, iron ore has been discovered and mined in several counties in Liangzhou, including Wuwei County, Hanyang County, Longxi County and Jincheng County.

There were iron smelting institutions in these places, but many of them were abandoned after the war.

After Liu Bei carried out the reorganization, he brought all of them under the jurisdiction of the craftsmen of the Liangzhou Prefecture Pastoral Mansion, carried out unified production, gave the names of the first iron-smelting workshop and the second iron-smelting workshop, and improved the main iron-smelting methods.

In the middle and late Western Han Dynasty, the steel frying method began to appear in China, and the ensuing steel-making technology also began to appear.

However, there are still certain defects in the steel frying method and the 100 steelmaking technology, such as the complex steel frying process, which is not easy to master, and the 100 steel making is labor-intensive and time-consuming, and a lot of useless work is done during forging, such as Cao Cao wants to make a good knife, and it takes three years to forge eight mouths.

Of course, despite this, these technological products can only be enjoyed by high-level figures, and they are definitely not popularized to the point that the small people of Shengdou can also enjoy them.

There is always a gap between the emergence of new technological methods and their full penetration in every corner.

In the core developed areas of the Central Plains, all kinds of technologies are relatively advanced, and there are also popularization, where there is technological innovation, as long as it is not deliberately hidden, due to the convenience of transportation, it can be spread within a few years.

In remote areas, because of the inconvenience of transportation and the de facto semi-independent tendencies of local governments, remote areas do not enjoy the benefits of technological innovation, and even use the technology of the previous era.

In developed areas, oxen can be used for ploughing, and cocoon carts can be used in the farms of wealthy households, while some farms in remote areas can only use wooden farm tools, spending more physical strength and time to complete simple agricultural production.

And so the gap widened.

This is true of agriculture and industrial technology, and the core developed areas of the Central Plains in the late Eastern Han Dynasty even appeared in the primitive form of the steel filling method due to the long-term technical summary of the steel frying method, and the blacksmiths in the remote areas are even using the block smelting method to make steel.

Because of the war, agriculture in the Liangzhou area was seriously deserted, but the popularization of iron-making technology was relatively good.

A considerable number of the blacksmiths Liu Bei collected after the war had mastered the method of frying steel, and even because of the once developed foreign trade routes, some blacksmiths passed down the smelting technology that was said to be in some countries in the Western Regions.

However, there is still a gap between the skills mastered by these blacksmiths and the skills mastered by the blacksmiths brought by Liu Bei from his hometown in Youzhou.

Because the blacksmith trained by Liu Bei in his hometown in Youzhou has basically mastered the essence of the steel filling method, although Liu Bei can't judge how far this technology has come from a very professional point of view, but this kind of thing has never happened in his blacksmith system.

After these blacksmiths in Youzhou's hometown mastered the essence of the steel-filling method, they even tossed out the double-liquid quenching method, which made the forging process after steelmaking more refined, and the quality of the steel used to make weapons was very high.

But because of Liu Bei's strict principle of technical confidentiality, they have never communicated with the outside world.

Other people don't know about secrecy, but Liu Bei attaches great importance to technology, and the principle of secrecy has been figured out very early.

He gave his blacksmiths who had mastered excellent skills very well, and he also took great care of their families, and the requirement for this was that they could not contact the outside world at will, and they needed to keep their core skills tight-lipped and never pass them on.

These technicians and their families are concentrated in the fixed area of Liu's Manor, and they need iron famous brands to enter and exit, and they are responsible for the procurement of materials and everything, so as to keep it confidential.

At least before Liu Bei reached the pinnacle of power, this kind of physical secrecy was very necessary, he didn't want the advanced technology he had worked hard to sum up by spending money and resources to be easily taken away, it would be too much of a loss.

Like the salt filtration technology, the steel filling method is also a technology that Liu Bei focuses on secrecy, and even the reason why Liu Hui and his intelligence department were born in the first place is that in order to keep the technology secret, secretly monitor and protect the craftsmen who master advanced technology.

Although Liu Bei is not too worried about leaking secrets with the contemptuous attitude of people in this era towards technology, the work that should be done must be done in place, and the attitude of doing everything is necessary.

They can not be taken seriously, I can not do without the principle of confidentiality.
