Since Li Xian began the research and development of crucible steel technology, he has attached great importance to written records, and various parameters such as temperature, time and ratio must be recorded in detail, which is a common and strict prohibition in modern society, but it is quite rare in this era.

The craftsmen of this era, especially the craftsmen of the Qing Dynasty, are mostly illiterate, but have not undergone professional training, and usually develop any formula to grasp some raw materials at will, neither to record each formula, nor to adjust the ratio according to the relatively systematic method, but all rely on luck and experience, which is much more backward than this rigorous and systematic research and development method, which is slow and uneconomical.

For a period of time after that, Li Xian had been immersed in the steelmaking research institute in the blessed land, constantly improving the furnace structure and the design of the steam engine blower, and also trying to improve the performance of the graphite crucible, and finally realized the universalization of a variety of knife steels and special steels, that is to say, there is no need for innate or fourth-order masters to join, and ordinary craftsmen alone can produce qualified tool steel outside the blessed land.

Once this is done, the output of tool steel can be greatly increased and the cost can be reduced.

It's just that the increase in output and the decrease in cost are relative, compared with one hundred catties of hexagonal pig iron and one hundred catties of gross iron (unwrought wrought iron), the cost of this tool steel is still dozens or hundreds of times higher.

Li Xian knew in his heart that crucible steelmaking itself is not a method that can obtain a large amount of steel, but is only used to produce various special steels, and by the way, to explore steelmaking technology, if you want to obtain a large amount of steel, you also have to explore open-hearth steelmaking or converter steelmaking.

Fortunately, with the support of crucible steelmaking technology, it will be easier to study these two technologies.

As for masters such as Xuan Zheng and Yuan Fang, they also refined the taste in the steelmaking process, and also tried various steel formulas and production methods in the blessed land, and most of the finished products produced in the process were sent to Li Xian to make various tools needed for military production, but a small part was embezzled by them to produce various swords and even armor by themselves.

In Chinese, the sword is often described as sharpening iron like mud, and the steel made by the crucible steelmaking method originally existed to cut iron, and its quality far exceeds the category of ordinary treasure knives, and only the divine weapon made of very special materials such as meteorite iron and Xuan iron can be stronger than this tool steel, but its quantity is relatively small.

There is a relatively stable standard for the evaluation of the quality of swords in martial arts, that is, the swords created by ordinary blacksmiths are ordinary;

Among them, there are occasional particularly good quality knives, which are called high-grade, and the jungle knives used by Li Xian in the early days are made of high-quality European steel, which are quite high-quality high-grade knives, close to the level of treasure knives;

The top grade and above are treasures, the quality has jumped significantly compared with the top grade swords, the hair is blown and the hair is broken, and the sword used by Zuo Lingchen at the beginning is a rare sword;

Above the sword is the famous sword, the sharpness and solidity are still above the treasure, and there are various stories, which have been passed on for dozens of hundreds of years;

On top of the famous tools are divine weapons, made of magical materials such as meteorite iron or dark iron that are rare in a hundred years, sharpening iron like mud, and a variety of other peculiar characteristics, like the dragon slayer knife and the sword of Yitian, which are incomparably sharp, and can also carry the inheritance of martial arts, which is the characteristics of divine weapons.

The sharpness of the sword made of the knife steel made by Sanyuan Fudi is only a little worse than that of the divine weapon, and the sharpness and solidity are still above the ordinary sword and sword, and in terms of pure physical performance, it is a famous sword and the like.

Therefore, this kind of sword made of steel was loved by many warriors as soon as it was born, and it was considered a rare fine product with high collection value and practical value.

Li Xian verbally criticized Xuan Zheng and the others' loser behavior, but he couldn't help but use particularly high-quality knife steel to create a knife in the form of a jungle knife as a self-defense.

After the capture of Guangzhou, many people thought that Li Xian would make a big move in Guangzhou, and even use troops in Guangdong, but in fact these predictions all failed.

After the occupation of Guangzhou, Li Xian and Xuan Zheng and other masters retreated to the Sanyuan blessed land, leaving only Wang Jiuxuan to govern in Guangzhou, receiving the assets left by the Qing government, seizing his family property after placing officials under house arrest, and establishing an administrative system in Guangzhou.

This change made many people shatter their glasses, that is, after Li Xian occupied Guangzhou, he made a big fuss with Sanyuanguan, and fought over who should preside over the affairs of Guangzhou between the mixed Yuanzong and Sanyuanguan, which was also more acceptable than the current move.

It's just that Li Xian has always thought that his foundation is not in Guangzhou, and should be in the Sanyuan Blessed Land, to be exact, in the Sanyuan Blessed Land, after obtaining enough materials and property from Guangzhou, he has no interest in governing Guangzhou.

Guangzhou, as the largest or only foreign trade city of the Qing Dynasty, has accumulated an astonishing wealth over the centuries, but there are few resources other than this wealth that Li Xian can look up to.

Guangzhou alone has no mineral resources, and daily necessities such as grain, firewood, etc., must be supplied by the whole of Guangdong and even large provinces outside the province, and its own production capacity is extremely scarce, and the products are not abundant, and it is even unable to achieve self-sufficiency.

As for industry, Guangzhou's handicraft industry is indeed developed, but Li Xian has already obtained Foshan's industrial system and workers before, and it will take a while to digest these, and now he is really not in a hurry to integrate Guangzhou's industry.

From the perspective of human resources, Guangzhou's population is quite large, but it is not of much use to Li Xian.

Let the people of Guangzhou be soldiers, after all, these people are pampered city people, not willing to endure hardships like farmers, and their ability to survive in the wild is also very poor, and the salary they want is much higher than that of farmers.

Let's recruit workers in Guangzhou, at present, there are many workers in Li Xian's hands, the total number of more than 8,000 people, low-end jobs are more economical to recruit from farmers, as for the middle and high-end jobs, the workers trained by the handicraft system in Guangzhou can not do the work with high technical content, and they have to be retrained, and the wages are still very high.

After calculation, Guangzhou's biggest advantage is that there are a large number of talents who have been engaged in maritime trade, but Guangzhou has always collected all kinds of materials from all over the Qing Dynasty and sold them to merchants from Britain and other countries, rather than their own locally produced goods.

Even Britain has experienced many major wars with the Chinese Liberation Army, and it is difficult to improve relations in the short term.

Considering that Britain accounted for nearly 90 percent of the Qing Dynasty's foreign trade with European countries, it is clear that even if countries such as the United States and France fill this gap, it will be difficult to do anything in the short term.

This is also the reason why Li Xian led everyone to plunder a large number of materials in Guangzhou, and he was not interested in Guangzhou and directly threw it to Wang Jiuxuan for governance.

If everything can be carried out according to Li Xian's wishes, Li Xian is more willing to plunder the materials and money worth more than 10 million taels of silver in Guangzhou, and then directly withdraw from Guangzhou, and use such a huge amount of materials to develop in Leizhou and Qinzhou, which are relatively remote, with large populations and low incomes, and can train two or three hundred thousand troops in two or three years, and then they can sweep the world.
