In the workshop, in the room serving as a training workshop, there were several machines quietly lying down. Li Li looked at these teaching tools and remembered his hard work over the past few months.

He referred to the principles of later fish hook automatic production machines and made a copycat version of the fish hook production device. After several debugging, he finally had practical value.

With the help of the wire drawing machine, the production of each fish hook semi-automated production device (divided into multiple sub-devices) in his field is currently producing 2,000 fish hooks (medium sizes) per hour.

If each set of equipment produces 8,000 fish hooks for four hours a day, this is just the result of the employee not very skilled in operating and the yield rate is relatively low.

No one would believe that such production speed is true if you say it, and Li Li would not say it either.

When the employees become proficient, the human-machine run-in and the machine structure is optimized, the production speed will be faster.

Of course, the semi-automatic fish hook production device was designed by Li Li himself, and then the carpenter asked to make a wooden model, confirm that it can be run, and then disassembled.

All metal parts are made by blacksmiths, and then cast various cast iron parts, such as various gears, are mass-cast.

Li Li himself reshaped the parts and slowly assembled the machine. Many parts remained as spare parts. Currently, three sets of production devices are put into production.

This is his "entrepreneurship project". Starting last year, after more than half a year of preparation, it finally officially started construction. It produces four hours a day, and the rest of the time, using a water wheel to push the glue machine to make fish bladder glue.

Therefore, the production capacity of fish hooks in Li Li’s workshop is that when there is sufficient iron material, wire drawing machines and other machines are operating normally, and workers are not short of staff, currently 24,000 fish hooks are produced every day (not counting subsequent processing and packaging).

Excluding the cost of fixed assets such as production equipment, workplaces and early investment, the total cost of ten medium-sized fish hooks is four.

Store price, ten fish hooks are sold for twelve cents, "wholesale price" (starting from one thousand pieces), and ten fish hooks are sold for 8 cents.

On average, Li Li can earn four cents for every ten fish hooks and produce 24,000 fish hooks every day.

That is, earning 9,600 yuan a day (based on production and sales), summarizing it, and counting the daily profit of 9 jin (silver).

On the 24th day of production every month, the profit is 216 knots. After deducting the monthly interest rate of 200 knots, Li Li can earn 16 knots.

In the future, when the machine is improved and increased, personnel proficiency will increase, yield rate will increase, and profit will be more profitable.

Li Li was 'adventure' outside for half a year. After returning, he had money. The four million yuan borrowed from the Huang family was purely for the sake of abundant working capital.

The debt is nothing when the workshop starts to make money.

But who would believe this kind of thing? Others would just find it unbelievable, because no matter how you look at the little fish hook, it doesn’t look like you can make a lot of money.

Li Li turned to the room and looked at more than a dozen female workers packing fish hooks, looking at the busy figures inside and out, very satisfied.

The "solid carburizing" process used in the production of fish hooks has matured this era, but it is not called this name, and an experienced master needs to check it.

The use of "carburizing agent" in the workplace is just the carburizing agent used in the "fish hook soil carburizing" he heard in his life:

Fifty percent of charcoal (ground into powder), 30 percent of chaff, and once it becomes wood ash, the remaining 10 percent is a common sauce. This carburizing agent can nitride while carburizing.

The processed fish hook is tough and durable.

Oil quenching and tempering are the commonly used treatment processes in tool making in this era, and experienced masters also need to be checked by them.

Li Li is not a master. He just "scientific" his process based on his own insights. It cannot be considered an invention, but only improvement.

For example, the temperature control of key processes depends on auxiliary judgment: the melting point of copper is about one thousand degrees, and the melting point of lead is about three hundred degrees.

Or look at the fire color when the steel/iron bars are heated: the temperature is about 500 degrees when it appears dark brown, and the temperature is about 600 degrees when it appears dark red.

Li Li walked out of the room and came to the shed beside the carburizing furnace. He took out an iron ring from the already cooled carburizing box. The iron ring was not big in diameter, like a small ring. He looked at the iron ring and showed a meaningful smile.

Cold-drawn wire, quenching, tempering, and carburizing technology should not be used only as fish hooks.

With cold-drawing technology, it is just used as a fish hook, which is a brain problem.

......

At night, on the first floor of the female worker's dormitory, in the office, Li Li was listening to the report of "Sheguan". Zhao Mengniang, who also serves as a sheguan, said one by one according to the rules and regulations.

Zhao Mengniang has management skills. After a period of inspection, she performed well, so she was promoted by Li Li to the workshop to take charge of the daily life of a female worker and had to check the room every night.

And see who is feeling unwell. If you should take leave the next day, you should take leave and if you should take a rest.

Zhao Mengniang has been following Li Li's requirements and managing the daily life of female workers according to the rules and regulations set by Li Li. She performed well for several months, and Li Li was very satisfied with this.

He lacks people, so even if he judges that Zhao Mengniang is very likely to be a meticulous work, he dares to use it as long as the other party has the ability. Even if he can't help it, it doesn't matter if he "eats" the other party.

After several months of observation, Li Li found that the young lady was of good quality: her understanding, induction, and expression skills were above the level. She would teach some knowledge and learn from others.

People look smart, handsome, and good figure. It is indeed a good material for me to do a detailed work and to practice the "beauty trick".

After Zhao Mengniang finished reporting, Li Li nodded: "Mengniang has done a good job, thank you for your hard work."

"This is the duty of a servant, it should be." Zhao Mengniang replied softly.

"No, the responsibilities may not be done well. After all, everyone has different abilities, so you are good, which surprised me."

As Li Li said, seeing Zhao Mengniang lowered her head shyly, thinking of the lonely man and widowed woman in the room at this moment, he coughed dryly: "You are busy from morning to night, so tired. I will give you an assistant, that is, a maid."

Zhao Mengniang shook her head: "I can do it, no need for an assistant..."

"No, you are responsible for managing your work and focus on your work. When you are doing your daily routine, washing clothes and cleaning, you will leave it to your assistant."

"You just need to be responsible for your work, and I need your left arm and right arm."

After hearing what Li Li said, Zhao Mengniang nodded vigorously: "I understand, I will work hard!"

"It's great, but don't be tired of yourself." After Li Li said that, he stood up and walked out, "It's getting late, you can rest earlier."

Zhao Mengniang hurriedly sent Li Li out. Looking at Li Li's back, she hesitated for a moment and asked, "Will the Lord be staying up late again tonight?"

She looked worried and saw Li Li nodding, and quickly said, "My mistress repeatedly reminded her that she should not let the man-in-law stay up late often."

"Just treat it as if you can't see it." Li Li smiled and continued to move forward.

He entered his "office", the servant took a break, then latched the door, lowered the curtains, opened the locked cabinet under the dim oil lamp, and took out a "sting suit" from it.

The "anti-sting suit" called later generations was "chain mail" and "soft armor" in ancient times. The name of the chain mail common in storytelling was called "ring lock armor".

Therefore, Li Li’s motivation was not “pure” since the beginning of planning to build a workshop. There are two types of products in this workshop. It is a fish hook on the surface and a product that is invisible in secret. It is a contraband product - armor.

And it is the high-end armor of this era: ring lock armor.

Mass production of fish hooks can make profits, and armor is one of his most powerful reliances in troubled times.
