In the city, houses rose from the ground and were divided into residential areas of family and craftsmen according to various functions, including military residences, military residences, soldiers' residential areas, canteens, bathrooms, warehouses, iron factories, shops and other buildings, and were arranged in an orderly manner. Although the city is not large, three to four-story buildings are built, so this small city can accommodate more than 30,000 people, and each building is extremely sturdy. As long as the houses are slightly renovated, they can become fortresses. Even if the enemy breaks the city wall and attacks the city, they will face fierce street battles.

The ability to build a solid building so quickly is all due to the special building materials fired by Li Guodong. In addition, there is more sand and gravel clay in the loess, and less ordinary clay. The method of burning bricks by Li Guodong, using sand and gravel clay, shale and coal ash, is extremely hard.

"This brick is so hard, it's as hard as a stone." When the craftsmen needed to knock the big bricks into small bricks, they realized that the blue bricks were extremely hard. It took a long time to smash one. The house and city wall made of this brick mixed with new building materials were simply iron walls.

In fact, according to Li Guodong's plan, his focus in the future is to be in the Touhu City Village in the Jianghuai area. In order to cope with the future entry of the Qing army, his strategic idea is to defend the two Huaihe Rivers to ensure the Yangtze River defense line. Even if all the four towns in Jiangbei are lost, he can insert an unplugged nail behind the Qing army! Especially the city walls built above Hongze Lake can blow up Gaojiayan at any time, flood Huaiyang, and cut off the traffic in the canal.

But Shanxi's defense cannot be relaxed. Shanxi is the roof of the North China Plain. As long as Shanxi is in the hands of the Han people, whether in the hands of the Ming Dynasty or the rebels, it can make the Qing army that occupied the North China Plain panic.

The next step is to build a city in various hilly areas of Shandong, and Shandong and Shanxi attack the North China Plain, and strategically surround the Qing army entering the pass.

The current Xiangling Camp is also the most important weapon production base. There are many coal in Shanxi. Li Guodong's craftsmen have already explored coking technology under his suggestion. With coking technology, they can produce steel with coking, which is much lower than charcoal iron making. With low-cost iron making technology, Li Guodong can consider producing barbed wire mesh. With barbed wire mesh, they can block the impact of the Qing cavalry.

As for how to deal with Qing armaments such as Wu Zhenchao, Tianyou, and Tianzhu Army, Li Guodong could only consider suppressing it with firearms that exceeded the Qing army's firepower. In future wars, the Han Eight Banners Firearms will definitely be Li Guodong's biggest enemy.

Xiangling is a good place with abundant coal resources and Fen River flowing through it. A group of water trucks can irrigate the farmland. This place was originally looted by bandits, and a large number of land became a homeless land. Li Guodong stationed his troops here, Lu Xiangsheng also stationed his troops in the Fen River Valley. Sun Chuanting stationed his troops in the Wei River Valley.

Li Guodong also had another plan, which was that after the Xiangling City was completed, he wanted to take people to Julu, prepare for digging a few tunnels there, and build a warehouse. To prepare in advance to welcome the invasion of the Qing army in the 11th year of Chongzhen, he wanted to survey the terrain in Julu first. When the Qing army invaded, a large number of barbed wire mesh would be transported to Julu.

Just when Li Guodong was vigorously building the Xiangling Camp, Wang Quan, who was stationed in the upper reaches of Hongze Lake, was also building a large-scale construction to expand his city. On the surface, Wang Quan had his own position. Because of his repeated military achievements, the thousand households he bought had been promoted to the commander-in-arms of the Guards, which belonged to the military households and did not recruit soldiers. Li Guodong's army belonged to recruit soldiers, and the two belonged to two systems. Of course, Wang Quan's real superior officer was not Dusi, but Li Guodong, but the people outside didn't know about it.
