Compared with Liaocheng Prefecture, the history of Xincheng Prefecture is shorter? New City, as the name suggests, is the newly built city.

It was established in the first year of Zongzhang in the Tang Dynasty (668), and originated from the first expedition of Emperor Taizong of Tang to Goguryeo in the east. As a shield for Liao County and to curb Goguryeo's foreign aid, it built a new city to protect the Liaohe River Basin more than 80 miles northeast of Liao.

Later, after the Tang Dynasty destroyed Goguryeo and set up the Andong Protectorate, it became the Xinchengzhou Governor’s Office, one of the nine Governor’s Offices. As the capital was located outside the Andong Protectorate in Pyongyang, the capital city was the new city (now the Beigao Mountain, Fushun City, Liaoning Province).

It controls the Marines and Liulin tribes in the central part of the Andong Protectorate, and also monitors the grasslands in the lower reaches of the Xiliao River and the Wei tribes in the Xilamulun River Basin.

Therefore, in addition to Xincheng Prefecture, the current subordinates include Yanjin Prefecture, South Suzhou, Mudi Prefecture, and Gaimu Prefecture. However, due to the recession of the Luo family, they currently only have corresponding control in Xincheng Prefecture and Gaimu Prefecture.

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

Therefore, Gaimu Town was established in Gaimu Prefecture, while Xincheng Prefecture became the garrison of the Dongning Army to suppress and fight against these former vassal forces that were supported by the Northern Alliance.

Among them, there is only a large area near the new city of Zhoufu, which is the direct leader of the Luo family, and the rest are subordinates and vassals related to the Luo family, and belong to about a dozen families of surnames.

Therefore, Luo Youning, the chief of the Xincheng Prefecture Governor's Office, can be regarded as the highest-level government chief among the local officials, second only to the heavyweight vassal families who are still in the hands of the Luo family and are still in charge of the Luo family and are appointed by the elders.

As a representative, he came here, Luo Youning's eldest son Luo Qiren. This is a young man who is older than me, but he is very respectful and thoughtful. He calls me "uncle" the words of my son and nephew.

It was just called out by an adult who was older than me, Cheng Clan, instead of a cute loli. It made people feel a little uncomfortable when they were electrocuted.

Although the whole process is simple, I gave a valuable gift list including mink velvet, deer antler, and ginseng, in exchange for a few respectful and polite words when meeting and reminiscing about the relationship.

But after the family dinner, I came over to contact me without any suspicion all night, which was a sign of separation from my family.

And the other party's arrival this time was equivalent to indirectly confirming something and important information for me.

According to the information and intelligence analysis I have collected before, I have heard something vaguely:

With the turmoil and changes in the Northern Dynasties over the years, there have been constant within the Anton Daluo family in recent years. The two factions that the family advanced westward and northward:

Among them, the North-bound faction advocated taking advantage of the decline of the Northern Dynasties and having no time to look east and put pressure on Anton to disturb the wind and rain, and to go north to attack and recover those rebellious ministers and vassals, and re-establish the authority of the heads of the Andong princes;

Then, the princes of the Northern Alliance who were under the banner of neutral observation and were in a state of being on the verge of being on the verge of rats, and one by one to deal with the enemy forces around them.

The other faction advocated a decisive and large-scale advance westward, and in one go, eliminating the basic foundation of the Liaoxi and the five tribes under the jurisdiction of the five tribes, which were owned by the enemy Xue family, completely cut off the greatest excuse of the Northern Dynasties' intervention and intervention in Andong, and then conquering the north.

This is actually just a sequence of directions toward north or west, from difficult to easy toward, and they all have their own sufficient reasons and positions.

However, Luo's continued decline over the years, and its territory and resources have shrunk.

And my arrival seemed to have become an external factor and bargaining chip within Anton Roche. Regarding the next strategic direction and differences, it is quite important.

Therefore, I seem to be able to speculate and expect that the so-called basic strategy of intercourse and attacking near and near this time, Anton Daluo implemented the diplomatic activities of observing ceremony and witnessing.

For example, Huaidong, which had a common hostile position with the Northern Dynasties, brought up the banner of the Southern Dynasties to echo politically and militaryally, and thus gained more response and appeal among the Andong princes.

The succession ceremony for the handover between the old and new family heads is obviously an opportunity and reason.

At the same time, next to a Heyun Wharf in Huaidong, there is a new large factory, which has completed the layout and commissioning of steam machinery.

However, it is a steam-driven drum ball mill, connected to a large tower-type fire kiln, which began to provide the first batch of cement production among the rolling black smoke and dust.

The cheers and smiles that echoed for a moment also filled the faces full of dust and dust.

As one of the legacy of the ancestors of the time traveler, the Southern Dynasty already has the existence of primitive cement called gypsum. After the textbook is shaped by water, you can try the gene as solid as the head.

The corresponding sources are mainly sediments of silicates and volcanic ash from outer sea islands.

However, key technologies have always been monopolized at the national level. Although they have developed in the past dynasties and have been widely used among the people, they have always been a kind of mid-to-high-end building material, and have been controlled by the court for a long time for related special sale and use.

In fact, there are also places for raw materials for firing cement limestone and gypsum under Huaidong's rule, and some of them are first-class and received special quality storage.

Therefore, limestone, clay, iron powder and other raw materials are grinded in a steam-driven drum ball mill according to a certain ratio, and then grind them into a very simple rotary kiln to calcinate them into clinker; then mix clinker, gypsum, and mixed materials (such as slag, fly ash) according to a certain ratio, which is the most basic cement.

Since almost most of the auxiliary materials and ingredients are available locally, there is also a sufficient supply source for fuel; the rest is to try the most appropriate ratio and temperature again and again in the context of repeated failures and accidents.

The primary cement produced by Huaidong, which was built in a closed-door manner, was obviously lower in size. Although it could not solve the strength required for high-rise buildings, the period of dry-hardening in the shade was relatively long.

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

When used in low-rise buildings, it is much more time-saving and cheaper than traditional Sanhe soil.
