At the end of September, the three blast furnaces and 18 hidden forts in Shepan Mountain were completed as planned, during which Yuan Sihai recruited more than 300 experienced miners to provide a steady stream of black iron ore for the three furnaces. Black iron ore is the main material for refining refined iron, 2,000 catties of black iron ore can be refined into one catty of refined iron, the refining process is cumbersome, at least three times need to go through calcination and quenching.

The three refining furnaces are used to refine refined iron, the black iron ore is a top resource for any Xiuzhen sect, if you know that there is a black iron ore here, you will definitely take it for yourself at all costs, which is why Wei Wuxian wants to set up eighteen hidden castles nearby, this place is top secret, and no one can be allowed to enter within ten miles of the vicinity.

Shen Tao's militia also all moved into Shepan Mountain, among which the unit led by Ji Yun last time was named 'Zhanzi First Battalion', and the treatment and rights were different from other people's bravery, and became the backbone of Wei Wuxian.

Ling Molin on the periphery was still recruiting people, and according to Wei Wuxian's plan, at least a scale of more than three thousand should be formed, about thirty battalions, each battalion of 100 people, and a team of 10 people.

Therefore, in addition to the 'essence of water', Wei Wuxian began to use the privileges in his hands to merge and integrate the merchant groups of Yan, Ling, and Li, with Ling Molin coming forward and Zhen Zongrui, the new captain of the Sanzhou Patrol Colonel, to integrate thirty-five merchant groups of all sizes in more than a month to form the 'Tianbao Commercial Bank'.

All this went so smoothly, it would not work without the support of King Yan behind it, and after a long talk that night, the relationship between father and son had improved significantly compared to before. Of course, this is mainly because Wei Wujian and Wei Wujian were injured and died, and King Yan had to find a force that could compete with the prince Wei Wuchang and Wei Wuyi.

'Tianbao Commercial Bank' has a wide range of business, tentacles throughout the entire Great Xia Dynasty, Ling Molin as the representative of Wei Wuxian in which the big treasurer, the original thirty-five business groups according to the scale, sent one or two people to serve as the leader, although these people are Wei Wuxian coerced into shares, but because their own interests have not been damaged, and there is Yan Wangfu as a backer, although there is still some unwillingness, but no one makes trouble or disobeys the control.

A virtuous circle has now been formed on the part of the vigilante groups. After the battle in the Stone Valley, Ji Yun himself has also been sublimated to a certain extent, and he has become more planned and purposeful in training, and the strength of the entire regiment has been significantly improved again.

With all this arranged, Wei Wuxian once again set his sights on the newly built three furnaces and the black iron mining area. The black iron mining area is being mined in an orderly manner, and Yuan Sihai recruits experienced miners, as long as they are given the conditions they deserve, the problem is basically not big.

The smelting furnace is a bit troublesome, the refining of refined iron is different from ordinary ironmaking, it is quenched again after ironmaking, the degree of craftsmanship required is high, and the danger is also great, and three people were burned by molten iron in just a few days.

Wei Wuxian is also the first time that the eldest girl has been on the sedan chair, so she stays in the furnace for a longer time, and solves problems at any time, those blacksmiths have not read any books, but they have been immersed in this area for several years, even decades, after repeated tests, it was found that the main reason is that the furnace temperature is not enough, and the impurities in the black iron cannot be quenched out.

The old blacksmith told Wei Wuxian: "If the temperature is too high, the furnace wall will not be able to stand it." ”

Wei Wuxian was helpless, and came to Qingyefang City again, and through some understanding, he learned that the smelting furnace for refining refined iron should be doped with a refractory material, kuntu. So he bought 1,000 catties of kun soil with a lot of money according to the proportion, mixed it with clay and rebuilt the fourth furnace.

After everyone's efforts, in mid-October, one catty and two taels of refined iron were finally produced. This is a historic moment, and the independent refining of refined iron has special significance for Wei Wuxian's next plan and future development. For this reason, Wei Wuxian rewarded each blacksmith with ten taels of silver and ten acres of Yongye field, which made those craftsmen who were struggling on the food and clothing line in the past cry with joy, not to mention ten or two hundred silver, just ten acres of Yongye field is a family heirloom, so everyone is more diligent, and the depression of living in the Shepan Valley is swept away.

Now that the iron is out, you can start crafting the latest weapons. Wei Wuxian's first choice was spears. It is eight feet three inches long, made of iron, weighs sixty-eight pounds, the spear head is doped with one point of fine iron, and the spear body is doped with two points of fine copper.

The function of fine iron is to strengthen the spear head and make it sharper, and the function of refined copper is to make the spear body more flexible, and it will not break when encountering strong force. The sixty-eight-pound spear is one and a half people high, and it can't be played without a thousand catties of strength in the hand, so such a heavy weapon can give full play to the advantages of their body in the hands of the soldiers.

In addition, Wei Wuxian had planned to refine a batch of armor. The armor should be light and strong. The armor doped with fine iron was very heavy, and it was not suitable for soldiers with heavy spears to fight, so it was not activated for the time being.

Ji Yun's first battalion of Zhanzi was the first team to obtain new equipment, and Chen Zijun shook the spear in his hand excitedly, feeling that the weight was just right, the previous spear was only six feet long, and it weighed no more than a dozen catties, it was too light, and it felt fluttering when dancing, but it didn't feel it. The spear in his hand was long enough and weighty, and the sweeping and stabbing were quite powerful, and the toughness was even better than that of the wooden spear.

Tie Niu held the spear and made a few stabbing and lifting movements, a little dissatisfied, his strength was greater than Chen Zijun, and the spear in his hand would be a little heavier.

"Try this spear!"

Ji Yun in the distance threw the spear in his hand over, and Tie Niu stuck the spear in his hand into the ground and took the spear thrown over with one hand. I tried it and a big smile appeared on my face.

This spear is specially made for Ji Yun, weighing one hundred and eight pounds, dancing to hunt and hunt, and there are cyclones all around, so that when it is used on the battlefield, a spear goes down, and few can stop it.

The other people were envious, and a few of them tried to play a dozen times before their legs and feet were bad, after all, they had never eaten Lingmi, and the time for cultivating the eighteen-style military physical technique was also short, and their strength was far from being comparable to that of Hanging Eyebrows and others.

Wei Wuxian was very satisfied with the spear he had refined, he now had a lot of family assets, in addition to the nearly 10,000 lower grade Yuan Crystals obtained from the sale of Linggu in the past few seasons, there were also seizures from the last time.

Last time, a total of nine storage bags were harvested, and seven of them were storage bags for the two young Taoist priests and Wang Dashi. The other two should be Wei Wuji's two enshrined storage bags.

Among them, six storage bags are ten-square storage bags, and three are small storage bags on one side, and a total of 1,239 lower-grade Yuan Crystals, eight bottles of Yuan Qi Pill, four sword weapons, and seven blood blades were obtained. In addition, there was a lot of gold, silver and jewelry, no less than what he got from He Xinyin last time, and all of them were handed over to Ling Molin to integrate the merchant group and recruit Minyong.

Therefore, Wei Wuxian, who was not short of money, began to deliver the remaining surplus food to Shen Tao in a planned manner, and appropriately rationed it for Minyong, who was training.

Lingmi has a significant effect on improving the physique of ordinary people, and the people who have not been nourished by Lingmi are still not as good as Ji Yun and others who have only practiced for two months after four months of hard training, this is the difference, and the difference between people is sometimes very different because of that little difference.
