In the late Han Dynasty, the steelmaking technology was already very developed, although there was no way to compare with the steelmaking level of later generations, but the steelmaking technology of the Han Dynasty was not surpassed until the end of the Ming Dynasty, which shows that the steelmaking level of the Han Dynasty had reached a certain height at that time.

After the brick factory was put into operation, Gongsun continued to use those red bricks to build the ultra-high chimney used in the steelmaking blast furnace, and made a workshop more than twice as good as the previous one based on the red bricks, and carried out new steel production according to the steel mill settings in later generations.

The way of steelmaking during the Han Dynasty, coupled with the understanding of steelmaking by Gongsun Xu later generations, the Xiangping blast furnace began to be put into production.

Different from the blast furnace steelmaking in other places, the steel made in Gongsun Xu's steelmaking furnace is more than three layers better than the steel in other places, both in terms of hardness and other aspects.

This super good level of steel is Xiangping side of the blast furnace can not be reached, before Xiangping blast furnace opened steelmaking, the quality of the steel produced in the blast furnace is very poor, and the steel in the Central Plains can not be compared at all, it is precisely because of such a reason, Xiangping blast furnace steelmaking has not been abolished by the end of the Han Dynasty.

Youzhou's steel and weapons are arranged and dispatched by Luoyang, and after arriving in Youzhou, because Xiangping belongs to the border area, weapons and steel are occupied by other parts of Youzhou, and only a small part flows to Xiangping.

There are very few iron and steel items in Xiangping, that is, many of the tools used by farmers to farm are stone and wood products.

After the opening of the blast furnace of Xiangping steelmaking, the industrial chain of Gongsun Xu has undergone earth-shaking changes.

In addition to the need for steel for the army, whether it is real estate, mining and other aspects, a large amount of steel is needed.

The weapons in the army are being updated, if Gongsun Xu pointed to the emperor in Luoyang City, it is estimated that they can be sorrowful, since Gongsun Xu became Xiangping Taishou, Gongsun Xu has repeatedly asked Luoyang for money and food, steel, and weapons.

However, Gongsun Xu only had a small amount of food, not to mention weapons and steel, that is, the food was all drawn, and under normal circumstances, the food and grass that should be given to the soldiers were directly reduced by two-thirds, and the weapons were only given to the configuration of an army of 1,000 people.

These things are still what Gongsun Xu won by helping Gongsun Xu after giving Zhang Rang some follow-up treasures, otherwise, Gongsun Xu is afraid that he will not be able to get anything.

Farming needs good iron tools, all walks of life also need high-quality iron tools, mining needs better steel tools, only in this way the tools are complete, then we can usher in greater development.

After the large-scale blast furnace was put into operation, all the scrap iron products collected by Gongsun Xu were remelted, and these became finished products that Gongsun Xu was satisfied with.

Xiangping, which is now Liaoyang City, has an excellent iron ore production area, and during the period when Gongsun Xu settled in Xiangping, Gongsun Xu sent countless people to survey various mineral deposits.

After Gongsun Xu explained some of the prospecting knowledge and his subordinates in later generations, they carried out prospecting according to this method, and while Gongsun Xu was mining coal, he had already marked out in his map the places where excellent iron ore was produced.

Although these places that produce excellent iron ore are very different from the locations remembered by later generations of Gongsun Xu, they are actually able to produce a lot of iron ore.

In the beginning, the progress of iron ore and coal mining was very slow, because there were no tools at hand, but with the opening of the Longshoushan steelmaking blast furnace, there were no problems with the tools.

If you want to do a good job, you must first sharpen your tools. If a craftsman wants to do his job well, he must first make the tool sharp. The same principle applies to Gongsun continued mining.

If you want to get more ore and more coal, you have to have good tools.

The current situation is that Gongsun Xu has formed a small industrial chain on the side of Xiangping.

The coal produced by the excavation of coal mines is supplied to steelmaking blast furnaces, brick burners to brick factories, and large households in Xiangping City that need coal for winter heating.

The fired bricks and the smelted steel were used in the construction of Xiangping City, and they were also used to take advantage of the mining in Xiangping.

After producing hundreds of thousands of bricks, Gongsun continued to gather his craftsmen who could build houses.

Gongsun Xu gathered these people together and passed on the knowledge of his later generations to build a large factory, and asked them to build barracks and other buildings according to some of the data and shapes he gave.

After the bricks were developed, Gongsun Xu did not put the construction of barracks in the main position, but built the kind of large boilers, chimneys, blast furnaces and other important things, and the most important thing needed for the construction of these things was the red bricks that were formed.

Gongsun Xu was going to build several large blast furnaces, cement factories, and steel mills and other most important things on this side of Longshou Mountain, and he knew in his heart that these were his fundamentals, and they must be firmly controlled in his hands.

It is the first choice to put it on the side of Longshou Mountain, after all, the geographical location and various conditions of Longshou Mountain are suitable for Gongsun Xu to do this thing.

Especially in terms of defense, even if he gives the enemy thousands of troops and horses, and his men only have a few hundred people, he can still firmly control Longshou Mountain without losing.

After researching such things as bricks, Gongsun Xu turned his attention to the cement products again.

Bricks and soil cement have been studied, and large-scale factories can be built, and the first thing Gongsun Xu wants to build is several large-scale brick factories, cement factories and large-scale steel-making plants.

In Liaodong, there is no fear of pollution now, but after the cement is made, it has a wide range of uses.

The viscosity produced by the mixing of cement and sand is amazing, and it is extremely strong after drying, this kind of thing is definitely a cross-era product, once it is produced in Liaodong, then it is extremely important for the development of Liaodong.

For these things like sand and gravel, Gongsun Xu has already arranged for countless displaced people to clean up the river of the Liao River.

In the era of the late Han Dynasty, few people would specifically clean up the river, and Gongsun Xu was afraid that it was the first one.

Gongsun Xu not only sent special personnel to control the Liao River, which flooded during the flood season, but also sent special personnel to conduct hydrological monitoring of these rivers.

The most commendable thing is that the fishing industry was very backward in the late Han Dynasty, and there were no professional fishermen.
