Compared with Liaocheng Prefecture, the history of Xincheng Prefecture is shorter. The new city, as the name suggests, is a newly built city.

In the first year of Tang Zongzhang (668), it originated from Tang Taizong's first eastward expedition to Goguryeo, as the screen of Liao County and the foreign aid to contain Goguryeo, and in the upper reaches of the Liao River, more than 80 miles away in the northeast of Liao, a new city was built to defend the Liao River Valley.

Later, after the Tang Dynasty destroyed Goguryeo and set up the Andong Metropolitan Protectorate, it became one of the nine metropolitan governors, the Xincheng Prefecture Governor's Mansion. As a seat of governance, it was located on the periphery of the Andong Metropolitan Protectorate in Pyongyang, and the state city was also a new city (now North Gaoer Mountain, Fushun City, Liaoning Province).

In order to control the Jinya and Liulin tribes in the central part of the Andong Metropolitan Protectorate, and also monitor the grasslands in the lower reaches of the Xiliao River and the Murowei tribes in the Xilamulun River Basin.

Therefore, in addition to Xinchengzhou, it currently has Yanjin Prefecture, South Suzhou, Mudi Prefecture, Gaimu Prefecture and other four prefectures. However, because of the decline of Roche, it currently only has the corresponding control in Xincheng and Gaimu states.

The largest seven-surnamed princes in the other three states, who were once vassals of the Luo clan, all broke away from control and joined the Northern Alliance decades ago, and were in a state of long-term staggered confrontation.

As a result, the town of Gaimu was established in the territory of Gaimu Prefecture, and in Xinchengzhou, it became the garrison of the Dongning Army to suppress and confront these former vassal forces that received support from the Northern Alliance.

Among them, only a large area near the state capital Xincheng is the direct collar of the Luo family, and the rest are subordinates and vassals related to the Luo family, and they belong to more than a dozen families with various surnames.

Therefore, Shi Luo Youning, the governor of the Xincheng Prefecture Governor's Mansion, can be regarded as the highest-ranking chief of government among the local acting officials, second only to the heavyweight feudal family under the Governor of Jian'an Prefecture and the Governor of Liaocheng Prefecture, which are still in the hands of the Luo clan and served by the elders of the family.

Coming as a representative, it was Luo Youning's eldest son, Luo Qiren. This is a young man who is older than me, but he is very respectful and courteous, and calls me "Uncle Clan" to my son and nephew.

It's just that an adult older than me called Uncle Cheng, not a cute Lori, can't help but give birth to a lot of goosebumps all over the body, and I feel very uncomfortable.

Although the whole process is just simple, send a valuable gift list including mink, deer antler, and mountain ginseng, in exchange for a few respectful and kind words when you meet, and talk about kinship.

But after the family banquet, he took the initiative to come over to make contact with him overnight, which had a sense of being different from his family.

And the arrival of the other party this time is equivalent to indirectly confirming one thing and important information for me.

According to the information and intelligence analysis I have gathered before, I have vaguely heard this:

With the turmoil and changes of the Northern Dynasty over the years, there have been two factions of claims and controversies in recent years within the Andong Da Luo clan about whether the family is moving west and going north:

Among them, the northern faction advocated taking advantage of the opportunity of the decline of the Northern Dynasty and the lack of time to look east and exert pressure on Andong and disturb the storm, and go north to crusade against and recover those rebellious vassals and re-establish the authority of the head of the princes of Andong;

and then suppress and integrate those Northern Alliance princes who are sitting and watching under the banner of neutrality, and the fact that they are acting at both ends of the rat, and clean up the surrounding hostile forces one by one.

The other faction advocated a decisive westward advance, destroying the Liaoxi and the basic forces of the five divisions that were owned by the feud Xue clan in one go, completely cutting off the biggest excuse for the Northern Dynasties to intervene and intervene in Anton, and then Xu Tu the north.

In fact, this is just a sequence of going north or west, from difficult to easy or from easy to difficult, and it all has its own good reasons and positions.

And Roche has continued to weaken over the years, and its territory and resources have shrunk.

And my arrival seems to have become an external factor and bargaining chip within Anton Roche about the next strategic direction and disagreement.

Therefore, it seems to me that I can speculate and anticipate the so-called basic strategy of long-distance and close-range attack carried out by Anton Da Roche this time by means of diplomatic activities of observing and witnessing.

For example, Huaidong, which unites with the Northern Dynasties, which has a common hostile stance, incidentally raises the banner of the Southern Dynasties to echo politically and militarily. And then gain more response and appeal among the princes of Anton.

And the succession ceremony of the handover of the old and new heads of the family is obviously some kind of opportunity and reason.

At the same time, on the edge of a river transport wharf in Huaidong, there is a new large-scale workshop, which has completed the steam? Deployment and commissioning of machinery.

However, it was a steam-driven drum ball mill, connected to a large tower-type firing kiln, which began to provide the first cement production in the midst of billowing black smoke and dust.

Suddenly the cheers and smiles resounded for a while, and then filled the faces that were full of dirt and dust.

As one of the relics of the ancestors of the traverser, the Southern Dynasty Liang actually already had, the existence of primitive cement called fossil paste, after taking this kind of teaching materials into water shaping, the gene can want to try the head of the solid.

The corresponding sources are mainly silicates and volcanic ash deposits from offshore islands.

It's just that the key technology has been monopolized at the national level, although it has developed in the past dynasties, and there has been a wide range of applications in the people, but it has always been used as a kind of high-end building materials, and has long been controlled by the imperial court to sell and use the relevant benefits.

Under the rule of Huaidong, there was actually no shortage of raw materials for limestone and gypsum for burning cement, and some of them were still first-class and super-quality storage.

Therefore, limestone, clay, iron powder and other raw materials are ground finely in a steam-driven drum ball mill according to a certain ratio, and then sent to a very simple rotary kiln for calcination into clinker; After mixing and grinding clinker, gypsum and mixed materials (such as slag and fly ash) according to a certain ratio, it is the most basic cement.

As almost all of the excipients and components are locally available, there is also an abundant supply of fuel; All that remains is to try the most suitable ratio and temperature again and again in the midst of repeated failures and accidents.

And Huaidong finally made this kind of primary cement with a low grade behind closed doors, although it cannot achieve the strength required for high-rise buildings, and the cycle of drying and hardening is relatively long.

However, it is still quite good as a hardening adhesive for pavement or a plasticizer for repairing buildings, especially when mixed with coal ash and iron slag from mines, which can significantly improve the service life of pavement and reduce the cost of maintenance cycles.

Used in low-rise buildings, compared with the traditional three-layer soil, it is more time-saving, trouble-saving and much cheaper.

PS: Mmmm, that's all for the time being, sorry
