Xu Chuan's desire to restart blast furnace ironmaking to produce steel and create weapons for the town guards is sincere, but it doesn't mean that he won't do any secrecy measures.

The establishment and operation of the blast furnace ironworks must be inseparable from the help of other residents, and coke is not easy to keep secret, to be honest, people can understand it with a little attention.

But the materials and proportions added in the ironmaking process are not so easy to explore, which is the best way to keep secrets.

Even if others know that blast furnace ironmaking requires coke, they can successfully copy it, but without knowing the added materials and corresponding proportions, what is smelted is also scrap iron.

Of course, this is not omnipotent, others will also grope for additives and proportions, but the Xu family and Sanzhi Town will also improve.

By the time someone else has figured out the addition and proportions, maybe they'll have a better way to do it.

Although Xu Chuan doesn't know much about ironmaking and steelmaking, as a modern person, he still knows about common alloys such as chromium alloys, titanium alloys, nickel alloys, and manganese alloys.

Although I don't know the specific addition ratio and forging method, I can figure it out by pointing out the direction and slowly groping for it.

......

Hearing Xu Chuan's words, the old man's frowning brows stretched, and he nodded in approval: "This method is good, although the materials added to the iron are common, but the blast furnace ironmaking needs to be blended according to the proportion, and if the proportion is slightly different, the steel will be wasted." ”

Xu Chuan smiled and continued: "In addition to keeping the ingredients and proportions secret, we also need to get a smaller furnace to experiment with all kinds of steel. ”

"For example, what happens when you add copper to molten iron, or what kind of material is added to make molten steel harder, and so on."

"There is a high probability that we will not be able to guarantee that the blast furnace ironmaking technology will not leak out, but as long as the steel we make is better than others, it is enough."

"As long as we keep having better steel, then we can stay ahead of the curve."

"And when our second and third generations of good steel come out, the first generation of raw steel can be sold out, and the steel forged by blast furnace ironmaking technology is believed to be bought by many people at a high price."

"In this way, we can not only make money, but also keep our lead, even if the steel knives sold fall into the hands of bandits, don't worry, the knives in our hands will be better."

“......”

The more Xu Chuan spoke, the more excited he became, and he directly spit out some of the tricks of the later generations, and the old man who listened to all kinds of ideas and suggestions danced with his eyebrows.

Although these are not new tricks in later generations, many countries in later generations have done so.

Whether it is materials or equipment, they are constantly researching and developing, constantly stockpiling new technologies, using them well, and exporting them poorly, which can not only make money, but also block the independent research and development capabilities of other countries.

And as soon as other countries show signs of catching up, they will immediately launch a new generation of products and suppress them to the death, which is not a very clever trick, but it is very effective, and he crossed the former motherland, which was deeply poisoned by this method.

It's just that in this era, everyone's thinking is still at the level of how to keep the technology they have developed secret, so when the old man heard it, he only felt that his mouth was suddenly opened, and he kept nodding in approval.

Dotting and pointing, the old man suddenly raised his head and scolded: "Profiteer! ”

Xu Chuan: "......"

........

After handing over the matter of blast furnace steelmaking to his old man, Xu Chuan returned to Xu's house, called over the maid Qi Xiaoyun, gave her some broken silver, and asked her to help buy some baku leaves and spices.

The training of the town guards cannot be done for the time being, the barracks site and these things have not yet been built, and the town guards still have to face some battles.

He had asked Ji Liang before, and the man who had led the guards against the bandits before had calculated and told him that before that, the town guards had resisted several invasions of the bandits, and they would probably have to resist two or three large-scale bandit attacks in the future, and then there would be a period of calm.

This lull period will last until the late rice harvest in October, which is about two months and three months.

When the late rice is harvested, those bandits will attack and loot the town of Sanzhi and loot the grain.

Of course, small groups of people have always been involved in stealing, robbing and harassing residents.

Therefore, after Xu Chuan is ready to deal with these two or three waves of bandits, he will use the calm period to train the town guards, and develop the town at a high speed.

Half of the main sources of food and military pay for the guards are contributed by the residents of the Sanzhi Zone, and half are promised by him.

But the inhabitants who have been plagued by bandits for many years are themselves very poor, and although there are tens of thousands of them, it is not a problem in the long run.

And he doesn't have any money of his own, so he has to find a way to increase his income and build a virtuous circle.

Tobacco leaves, salt, toothpaste, toothbrushes, soap and other common items in daily life are Xu Chuan's goals.

These things were not difficult for him, who was a chemistry major before the crossing, to make them, and he could probably get them out after a few more experiments.

Selling these things to caravans, the people can obtain money, and only then can they support the training and expansion of the town guards.

After the town guards have formed sufficient combat effectiveness, they can in turn protect the three areas, forming a virtuous circle.

Interestingly, some bandits also do business.

It's just that they are doing business without capital.

There are too many bandits in the Sanzhi area, and the forces are too complicated, and some bandit bosses will sort out the things they have looted during the calm period.

Then they would arrange for the younger brother to disguise himself as a merchant and sell cloth, spices, ceramics and other things looted from passing caravans to the inhabitants of the Sanzhi Zone.

Some of the supplies for the inhabitants of the Sanzhi area were bought from the bandits.

Xu Chuan couldn't help but be stunned when he heard about this before.
