Li Tianyang's visit, although it seems that there is not much progress, is actually a piece of peace and happiness for Hai Dafu.

After all, the mine is a national weapon, with the body of a rich local tycoon, if this mine is made public, it must be that the strong and rich people recruited are not something he can resist, even if he pulls up Li Tianyang, the military attache of the Ming Dynasty from the third grade, it will be useless.

Whoever let Li Tianyang have a deep foundation in the DPRK and China, and there is no other strong reinforcement except for relying on the eunuch party.

At this time, Li Tianyang said on the premise of Ni Wei's face, using lime and charcoal brick kilns as a cover, seeking Ni Wei's attention, as long as Hai Dafu is cautious and doesn't do that noisy thing, with his own relationship with Changhua County, it can basically be said that he has made a fortune quietly!

If it weren't for the fact that the magistrate of Changhua County was bribed by Hai Dafu, Hai Dafu would not have been able to mine for a long time without being known by the government.

And with Ni Wei's paper document, although Changhua Zhixian and Hai Dafu, who had long been embarrassed, could not mine openly, they also had a lot of scruples, plus Li Tianyang, who had just gotten on their thief ship, basically meant that their ship was already very stable.

The so-called county officials are not as good as the current management, although the prefect's power is large, but his jurisdiction is too wide, a county government like Changhua, basically it can be said that he has no chance to come, so with Ni Wei's paper document, the Changhua county order can be sold with Hai Dafu and Hai Dafu on the head of a sheep!

This is also Li Tianyang's reward for inviting him to join Hai Dafu!

More than a dozen cargo ships slowly sailed up the Changhua River until the nearest section of the river to Shilu docked, where large quantities of black-brown or crimson ore, which had already been transported by oxen and horse-drawn carts, were piled up on the humble wharf, waiting to be loaded onto the ship and transported to Bengang.

There are too many ores piled up, and more than a dozen ships of more than 2,000 materials specially selected by Li Tianyang are still unable to carry this batch of more than a very small part of Shiluling, even if these cargo ships are transported more than a dozen times, they may not be able to transport them all.

This gift was just too big, when Li Tianyang saw a large ship full of various ores transported off the ship and piled up in the port, listening to Wu Chao tell him about the ores that were still piled up on Shiluling, his whole person was drenched in sudden happiness!

If Li Tianyang had been exposed to geological knowledge at the beginning, he would not have been so surprised, as a rare high-grade iron-rich ore in China in later generations, and it is still an open-pit vein, the reason why Haidafu does not value these iron ores is self-evident!

"Hurry up and find them, and ask them to organize people to tackle key problems immediately, and give the best plan for smelting iron ore as soon as possible!" Li Tianyang almost used a roaring tone to give orders to Tan Songyun, who was following behind him.

"Yes!"

Although they have not been able to find traces of iron ore veins on Dayuan Island at this time, they have been preparing for the day of their reign when they tried to develop the gold veins of Jilong Mountain.

It's just that at that time, Li Tianyang and the others only collected the methods of the masters of this era to smelt iron ore, and there was no iron ore as a research material, and they couldn't make timely improvements to these for the time being.

However, the smelting technology of the gold ore in the Jilongshan Mine has a good reference for this, and in order to increase the production of ore in the Jilongshan Mine, Chengcai has made a lot of improvements to the ash blowing alchemy method of this era.

As Jilong Mountain began to build dams and use the power of nature to replace labor, in addition to saving a lot of human resources in Jilong Mountain, they also found that crushing the ore as much as possible can also improve the gold ore and other skills!

In the same way, many skills can also be used in the smelting of iron ore, with the coal mine excavated by the Yushan tribe as fuel, the dam that Bengang Creek has already built upstream of Bengang, and the gear transmission system (the bearing transmission mentioned above is wrong, it is explained here that with Li Tianyang's existing technology, the bearing transmission is still more advanced!). Soon, using the smelting techniques they currently collected, they improved many of these techniques and gave a more scientific smelting technique.

In the process of improving the iron ore smelting technology, Wan Liang, the leading construction master of the Bengang team, was also ordered by Li Tianyang to build a smelting plant on the edge of the Bengang Dam as quickly as possible.

When the iron ore smelting was officially released in time, the iron ore smelting plant that Wanliang and their urgent rush to work was also officially launched.

After many improvements to the cement, seventy is no longer much different from the cement formula of later generations, and it is with the help of cement that Wan Liang and they can urgently build a smelting plant in less than half a month.

There were a large number of indigenous slaves, and Li Tianyang didn't even need to recruit people anymore, but just recruited extremely smelting masters from the Jilongshan Mine to teach the indigenous slaves the specific details of smelting, as well as the ideas.

In just about a month and a half after the first batch of iron ore was transported, Li Tianyang personally witnessed the output of the first furnace of pig iron.

When Li Tianyang watched a basket of ore being crushed into fine sand and thrown into a furnace burning with coking coal, after some operation by the naked and sweating indigenous slaves, and then at a tap hole at the bottom of the furnace, the red molten iron slowly flowed out along the groove, and then slowly solidified into pieces of black pig iron, he almost jumped up.

The reason why Li Tianyang remembers using coking coal to make iron is also thanks to a book he had read at the beginning, which seemed to be called "Speculators of the Republic of China" or something, which mentioned some knowledge about ironmaking, which made him remember it vividly.

It seems that through the present, most of the things Li Tianyang learned from school have been returned to the teacher, and there is little knowledge that can be poured up, and they are all learned from various YY, thinking of this, Li Tianyang couldn't help but cry, and felt that he was too embarrassed to his teachers!

I didn't expect that the iron content of the iron ore transported from Shiluling is really not covered, and the ore of less than three stones can obtain about one stone of pig iron, counting the loss and the residual pig iron in the residue, I am afraid that the iron content is at least more than half!

The more this is the case, the happier they are, if the iron content of this ore is really so high, doesn't it mean that they will no longer have to worry about pig iron resources in the future?

Then wouldn't they be stupid as many artillery and muskets as they want to make in the future, then they can make as many artillery guns as they want, even if they become an arms dealer at that time, Li Tianyang is afraid that he will be able to do it well.
