Gongchangling, the place where Hongmen is now the center of gravity for development, a steady stream of materials are gathering towards this place, and between Gongchangling, which is not very high, there is a scene in full swing.

Thousands of high-rise buildings rise from the ground, although the Hongtang army Gongchangling fortress does not have a too high city wall, but the combination of stone and cement made of local materials, building a three or four zhang high city wall, is no problem at all.

Stone mining was so extravagant that it was the iron ore found that was used, and the need for labor was reduced to the lowest of its time when the colorful iron ore was mined with gunpowder.

The Hongtang engineers and technicians drawn from the Shilu mine have accumulated enough experience to observe the direction of the ore, drill a hole more than a foot deep at the key position, and then fill it with gunpowder and seal it, ignite and detonate it, and finally collapse and shatter the boulder ore several feet in a square circle like that skill of four or two thousand catties.

With these stones, supplemented by the filling of cement and steel, the fortress of Gongchangling soon rose from the ground and became the most conspicuous man-made structure in the surrounding hilly area.

And just behind Gongchangling, in the opposite direction to Liaoyang Castle in the Qing Dynasty, in the name of opening and building stones, the mine that was invested in early to verify the grade of the ore veins has started, and the first batch of smelted pig iron has been neatly stacked together and stacked in a tightly guarded warehouse.

Compared with the output of the Shilu Mine, the advantage of the Gongchangling Mine is more obvious, because the Iron Ore Mine is abundant, but it needs a lot of fuel to melt the ore into pig iron.

With the development of coal in Hongmen, the wood, charcoal and other fuels used in ordinary mines have long lagged behind, not to mention the great cost, and the waste of logs and the destruction of nature.

The combustion heat of coal is higher than that of wood, and the combustion temperature and time are needless to say, and its superiority is naturally not on the same level as firewood.

Shilu mine produces iron but does not produce coal, whether it is smelting pig iron on the spot, or sent to Dayuan Island for smelting after mining, it consumes too many resources and funds in transportation, but it is not as good as Gongchangling, there are both iron ore and coal output, which can be completely sourced from local materials, and the cost will be extremely low.

Of course, the Gongchangling Iron Mine is not without defects, and the pig iron produced in the early stage has been smelted into steel and compared with the steel of the Shilu Mine, and the conclusion is that the steel of the Shilu Mine is much superior to the steel of the Gongchangling Mine.

The material deviation in this comes from the subtle elements that have not yet been deciphered by the Hongmen R&D Institute, but it involves a discipline that has not yet made many breakthroughs in this era - chemistry, which cannot be solved overnight.

However, even so, even if the artillery cast from Gongchangling steel is inferior to the production of Shiroku Mine in terms of material, it has an extremely obvious advantage in material compared with any other artillery manufacturer of this era. Not to mention that it has obtained the advanced cannon casting technology of the West, combined with the technology developed by the Hongmen R&D Institute itself, its cannon casting technology can be said to have reached the peak of this era.

Combining the two compartments, Hongmen used the artillery firearms produced by Gong Changling, but it still has natural advantages, which can be described as goods in short supply.

In addition to these necessary fortifications, Hongmen also began to build a road between the strongholds of Gongchangling, Phoenix, and Maohel Mountain to facilitate the march and assistance between Hongtang's troops.

The Qing people still did not pay much attention to the construction of these grassroots, except for those important city strongholds, which were built between the important city strongholds, and the roads that connected the rest of the country were more than some weed-covered and bush-covered mountain roads and paths.

In addition to cultivating the land allocated to them, the people who were resettled in the rear would also build irrigation canals connecting their fields under the leadership of the Hongmen Civil Affairs Department in order to supplement their family expenses and earn a little money during their slack time.

The water resources in the Northeast are also abundant, but the Qing Dynasty and Ming officials in the north are unwilling to invest too much in this shoe, so that once there is a natural disaster, the people at the bottom will be miserable.

Whether it is on their Dayuan Island or in the Luzon Islands, Hongmen has always attached great importance to the construction of people's livelihood, such as the construction of roads and irrigation canals that are related to the lives and production of the people.

Just after the autumn harvest, the weather is gradually beginning to cool, the first season of grain crops have begun to be received, corn, potatoes, sweet potatoes and other crops from the West, the taste and food may still need to be used to the people, but it also makes the people feel the long-lost light of hope, and their hearts are full of energy.

The black soil in the Northeast has never been a barren land, and the granary is not in vain in later generations, although the territory controlled by Hongmen now, many of the land is still just newly reclaimed new land, and some are food crops that have been replanted in the wrong season, but the fertile land and the crops that are not picky about the land still make this autumn Hongtang Northeast Territory, and the people have the food for next year's spring.

Of course, if you want to truly achieve self-sufficiency, it is still a little worse, no matter how hard the farmers are to work, no matter how fertile the land is, and no matter how easy the crops are to grow and high yield, it is difficult to hide the influence of the previous war.

Because of the war, the people did not dare to go out of the dock fort to plant, and there were many more lands where crops were planted, but they were simply destroyed by the war and there was no harvest.

At least this year and next year, the people in the northeast will have to rely more on food support from Hongmen Dayuan Island and Luzon Islands.

At the same time, because of the negotiation contract reached with the Ming court, the representatives of the Hongmen Foreign Affairs Bureau and the Nanyang Chamber of Commerce have taken out their twelve points of energy, shuttling between the displaced people of the Ming Dynasty, tempting families with no place to come to the north to reclaim and work.

The Nanyang Chamber of Commerce's investment in the Northeast involves iron ore and coal mining that are not open to the public in Dayuan Island and Luzon Islands, which is also the premise that they have been sparing no effort to support Hongmen's war in the Northeast.

Now that they have temporarily occupied a large area of land south of Liaoyang and found the Gongchangling iron ore and coal mines, if this group of businessmen does not want to try to promote the exploitation of these mines by Hongmen, then they are really sorry for their identity as merchants.

In addition to raw materials, more people and labor are needed to mine iron ore and coal mines, and then smelt and cast them into steel and other materials, and then process them into firearms, steam engines, and other unique products of Hongmen, which are not only drooling among the members of the Nanyang Chamber of Commerce.

Therefore, the proprietors of these business owners dug the corners of Daming, Daxi, and Dashun to transport batches of population to the Northeast to fill the lack of population in the Northeast.
