After the completion of the transformation of Dongzhuangzi, Chen Xian began to move his household registration from all over the country to fill in Dongzhuangzi.

Chen Xian gathered all the strong laborers in the migrated population, and sent skilled engineering workers from all over the country to form a road repair team.

He wants to open the passage from Dongzhuangzi to Linqu!

As a lover of ancient war history, Chen Xian is very familiar with the rise of the Mongol Empire and the process of expansion.

After the first two temptations, Genghis Khan was completely sure of the weakness of the Jin Kingdom, so he really let go of his hands and feet in the third war of Jin.

This time, Genghis Khan's troops were divided into three routes, and the Chinese army went south along the central part of the North China Plain, burning and looting all the way, until the north bank of the Yellow River, and then turned to the east, until Haizhou saw the sea before returning.

The Middle Route Army divided into two partial divisions, led by Mu Huali and Tuolei, and marched to Shandong, of which Mu Huali followed the western foot of Lushan Mountain, took Jinan and Tai'an, and then went south and Genghis Khan turned in Jeju, while Tuolei went east along the northern foot of Lushan and fought until Laizhou Dengzhou before returning.

The right army was led by Wokotai and Chagatai, swept all the way down the plain area at the eastern foot of Taihang Mountain, until it reached the north bank of the Yellow River, turned west, entered Shanxi, went north along the central plain of Shanxi, hit the grassland, and then turned east from the grassland to Zhongdu and Genghis Khan

The Left Route Army, led by Hazar and Chen Nayan, swept north along the Liaoxi Corridor.

The left, center, and right armies almost plowed the North China Plain and the Shanxi region of Shandong, and few places were spared, and the western plain of Shandong was the hardest hit area, which is why Chen Xian let Laiwu and Tai'an in eastern China not go, but had to take over the barren Mengyin.

Mongolia's third war of gold from the first year of Zhining (1213, this year has three year names, before May is the second year of Chongqing, May changed to Ning, August Yan Yongji was killed by Hu Shahu, September Yan Xun succeeded to the throne, is for Jin Xuanzong, the year name Zhenyou, so after September is the first year of Zhenyou) July, until October of the second year of Zhenyou, fought for more than a year, North China and Shandong are wailing.

In this sweep of the Mongols, in addition to Yiyuan, Laiwu, Xintai, Mengyin and other places located in the Lu Mountains, only Yishui, Linqu and other places near the mountains on the eastern side of the Lu Mountains are still safe.

Therefore, after taking Mengyin, Chen Xian immediately turned his attention in this direction.

Because, Chen Xian believes that the years after the third Mongolian gold raid will be a very critical period.

Next, Chen Xian personally led thousands of workers, divided into dozens of engineering teams, and adopted the method of sectional construction and finally closed to build the mountain road from Yiyuan to Linqu.

There are mountain roads connecting Yiyuan to Linqu itself, and all Chen Xian has to do is to widen and strengthen these mountain roads and turn them into avenues that can be opened to cars and horses.

Of course, the new road cannot be built exactly according to the original mountain road, and the original mountain road is very steep because it does not take large vehicles, so such a section of the road needs to be re-planned.

As early as the expansion of Dongzhuangzi, Chen Xian led his engineers to cross the mountain road from Yiyuan to Linqu many times, and made detailed plans for the future road.

With the supply of a large amount of cement and other materials, after the efforts of thousands of people, the road from Yiyuan to Linqu took only half a year, that is, in late May of the first year of Zhining.

After opening the road to Linqu, Chen Xian immediately transported supplies along the road and built a new Zhuangzi by the Shihe River south of the Lujiazhuang ruins, which was still named Lujia Town.

The new town of Lujia was located in a triangular area sandwiched between the Shihe River and one of its small tributaries, and the two rivers were immediately adjacent to each side of the Zhuangzi, and Chen Xian built dams and diversion ditches at the upper reaches of the two rivers, and built two ditches on both sides of the Zhuangzi to drive the water wheels, and built more than forty water turbines.

Using these turbines as the driving force, Chen Xian built a cement factory, an iron-making plant, an iron-wrought iron plant and other factories in Lujia Town, among which the cement plant was the largest.

At the same time as the construction of Lujia Town, Chen Xian sent people to find two coal mines nearby, the coal mines in Linqu are not of high quality, most of them are bituminous coal and lignite, and the two coal mines found by Chen Xian are one bituminous coal and one lignite.

Fortunately, in the cement plant, the ironmaking plant does not have too high requirements for the quality of coal, the cement plant just needs coal as fuel, it doesn't matter the quality, the coal of ironmaking must be coking, after lignite is made into coking coal, it is actually more suitable for use as a raw material for ironmaking, because the coking coal made of lignite has high strength and good support, and the charge will not collapse, but high-quality coal needs to add loess to increase the support of coking coal.

In August, news came from the north that the Mongols were going south again!

In September, the news that Emperor Wanyan Yongji was killed by Hu Shahu reached Laiwu.

Beginning in July, Chen Xian left the construction of Lujiazhuang under the management of Zhang Ping and Lu Qing, the eldest of the Lu brothers, and began to inspect Yiyuan, Laiwu, Xintai, Mengyin and other counties, inspecting the construction of towns and factories, and the training of students and militia.

After more than a year, Chen Xian has basically digested the two counties of Xintai and Mengyin, and decisive results have been achieved in the training and education of the militia and students.

After more than a year of education, the young students have basically become literate.

Combat effectiveness has also been formed in various places, and field battles may not be possible, but in special terrain, such as defending cities and forests, they still have quite good combat effectiveness.

The newly recruited soldiers in Xintai and Mengyin have been stationed in Dongzhuangzi for more than a year, and Chen Xian personally supervised the training and education, and they also have combat effectiveness.

After this expansion, Chen Xian's army swelled from nearly 10,000 to nearly 20,000, the infantry increased from eight infantry battalions to sixteen infantry battalions and four regiments, and the cavalry battalions increased from six to twelve.

Because of the shortage of war horses, Chen Xian replaced the mounts of the horse infantry with horses and mules, and gave all the war horses to the cavalry and light cavalry, among which the cavalry was the best of the best.

The good news is that after nearly two years of development, Chen Xian's horse farm has begun to produce war horses.

Under the correct breeding method, the quality of the horses produced by Chen Xian Horse Farm is quite good, but the number is limited, and only more than 200 horses can be slaughtered this year.

In addition to the cavalry, Chen Xian's artillery also increased from two to six, of which four artillery companies were equipped into four infantry regiments, and two independent artillery batteries, which directly belonged to the General's Mansion.

Looking at the gradually growing army, Chen Xian's anxious heart gradually calmed down, and in this troubled world, he finally had the capital to protect himself.

The fort on the territory was reinforced, and the construction of the hydroelectric factory also made Chen Xian very satisfied.

The reinforcement of the fort has been completed in Xintai and Mengyin counties, the construction of the hydroelectric plant has also been mostly completed and has begun to operate, the cement has begun to accumulate rapidly, and a large backlog of iron materials and ironware has begun to be in stock.

Chen Xian ordered cement and a large number of tools to be transported to the town of Lujia in Linqu through the newly built road.

Because of the participation of cement, the construction of Lujia Town was very fast, and it was basically completed by October.
