Everyone entered the temple again, Yang He thought about it, and asked Yan Dezheng to bring his package. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

He took out the handcuff from it and said to Zhang Chuxun, "Can you take a look at this handcuff?" ”

Zhang Chuxun took it and said, "It's good." ”

He looked at it carefully, and his mouth was full of words: "It must be made by the master." ”

However, he looked at the side of the fire door, frowned, and skillfully pulled the hammer to the position to be fired, and then pulled the trigger.

"Smack, smack, smack." He tried a few times, and finally shook his head: "The reed is not good, it can't catch fire, and it may be pulled away." ”

Zhang Chugong also took the handcuff and watched, and also tried it a few times, frowned and said: "The reed was originally supposed to be Su Gang, but it was replaced with fallen steel. ”

Yang He said: "Is there a way? ”

Zhang Chujing hesitated a little, Zhang Chuxun and the eldest brother glanced at each other, gritted their teeth, and said, "Yes, it just so happens that there is corresponding steel on the villain's side." ”

He entered the backyard, and did not know where to rummage, and finally carefully took out a bag of things, and after opening it, there were some steel bars and ingots inside, with a fine texture, exuding the essence of metal, especially Shu Zhong Misshaped, with a reverse load, obviously after many times of tempering.

"Fourth, do you really want to use it? It's very expensive, and the boss is reluctant to use it on the bird's gun. ”

Zhang Chujing muttered, his face full of reluctance, as if the second stunned temper had flare up again.

Zhang Chugong glared at him, and looked at these steel bars with some reluctance, and smiled at Yang He: "These Suzhou steels were obtained by the villain by chance, and they were originally used for drill bits. ”

Minister Yang saw that Zhang Zhujing's face turned red, as if he was about to cry, and he said angrily: "Is this steel very expensive?" ”

Zhang Chugong stroked the steel, his face was full of cherishment, he said: "In the first two years, this Suzhou steel cost about five taels or three yuan per catty, and now it is estimated that it costs six taels of silver, and it is priceless. ”

Everyone gasped, this steel costs six taels of silver per catty, and the market is priceless?

They all looked at the steel in Zhang Chuxun's hand in shock, and instantly felt that the bag of Suzhou steel was extremely heavy, and Luo Xianjue even subconsciously moved away.

Yang He nodded, this price was in his expectation, this kind of tool steel has always been expensive, Daming good steel is scarce, five or six taels of silver per catty, it is normal to have a priceless market.

At the same time, he secretly sighed in his heart, there are too few good steels, and rare things are expensive, and such steel is unaffordable for ordinary people. Now the price is expensive, so the purchasing power of silver has declined, if six taels of silver are placed in the peaceful and prosperous era, converted into the price of rice, almost a pound of sugang is worth 3,000 yuan in later generations, which can be said to be sky-high.

So this kind of good steel, how can the government and military leaders be willing to invest in flintlock pistols? How can they afford to invest this money? Unless the price of steel is not much more expensive than refined iron, but at this point, what level will Daming's smelting technology reach?

A small spring is related to a series of advances in science and technology, just as the fire cap is also a way of ignition, which looks no different from a flintlock pistol, but is related to the progress of chemistry.

There is no good steel to make spring plates to improve the ignition efficiency, and no matter how good the flintlock pistol is, it will also be shelved.

He saw that the three brothers Zhang Zhugong were full of cherished expressions, reluctant to give up, knowing the meaning of this kind of good steel in their lives, and said with a smile at the moment: "This steel is extraordinary, let's keep it for later." ”

Zhang Chugong made up his mind categorically, and he said solemnly to Yang He: "Even if you surrender to the prime minister, you should serve wholeheartedly, why do you care about these things outside your body?" ”

He said to Zhang Zhujing and Zhang Zhuxun: "Second brother, fourth brother, start work." ”

……

Zhang Zhugong and the three turned on the fire, the three of them used charcoal, and saw Zhang Chuxun put on an apron, skillfully walked to the stove, took the tongs and picked up the charcoal inside, red light came out, it seems that the fire has been prepared all day.

Looking at the flames, Zhang Chuxun kept adding charcoal, seeing that the charcoal fire was almost the same, he took out a piece of sugang and put it in the furnace, and then watched the steel heat, burn red and soft, and the color slowly changed.

He looked at it carefully, and he could no longer see half of the shyness on his delicate face, full of professional demeanor.

Yang He nodded secretly, the heat of striking iron is the most important, there is no thermometer at this time, it is all judged by the blacksmith's personal experience.

Many people can't master this kind of knowledge for many years.

watched the steel change color to a certain extent, and then Zhang Chuxun clamped it out, not only him, but also Zhang Chugong and Zhang Zhujing both picked up the hammer and beat it together.

"Dingdingding......"

The sound of intensive hammering, the three brothers come and go, and greet them all on the steel.

Everyone next to them watched cautiously, and they didn't dare to come out, as if they were enjoying the sound of steel from that kind of music again.

Hammered to a certain extent, Zhang Chuxun inserted the steel into the furnace fire, and when the fire arrived, he took out the hammer again.

Generally, the material has to go through several forging and fire before the embryo comes out, but this is only a rough embryo, and the finished product will be completed after multiple processes such as quenching and fine grinding.

Special quenching is a very technical process, when to quench, how long to quench, all affect the quality of the finished product, quenching technology is to measure the skill of the blacksmith.

There are also all kinds of skillful use, hand strength control, etc., many blacksmithing apprentices can learn for more than ten years to become a teacher, and those who can learn in three or five years are almost all geniuses.

It can be seen that the three brothers Zhang Zhugong are part of the genius, and Zhang Zhugong also told Yang He earlier that he and Zhang Zhujing are not very good at firearms, they mainly play refrigeration weapons, firearms and other production aspects, and only follow the hammer.

This used to be the arrangement of their family, the eldest and second, fighting swords, spears and arrows, etc., and the third and fourth making all kinds of firearms.

In particular, his third brother Zhang Chuqian is a master in the middle, and Zhang Chuxun said that his skills are only half of that of the third brother.

But......

They didn't continue, and Yang He didn't ask.

There are too many tragic things in troubled times, and it is better not to touch many sad things.

……

After several forgings, Zhang Chuxun appeared in his hand with a fire sickle striking the rough embryo of iron and spring steel, and then Zhang Chuxun worked meticulously on the anvil alone, he beat it very finely, and then used a file to file some bulges and roughness, and then quenched and polished.

Eventually, these carefully crafted parts appeared in his hands.

Zhang Chuxun flicked the steel plate with his fingers, with a satisfied look on his face, he used a screwdriver to unscrew off the part of the handcuff, and put the steel plate and the fire sickle and other parts on it, one by one, the technique is very skillful, and there is a kind of focused charm.

Yang He saw that the screwdriver he used was a flathead screwdriver, which was not easy to use, and often destroyed the screw groove with an unstrong structure, making it impossible to screw out.

However, plum blossom knives and ordinary Phillips screwdrivers did not appear until the thirties of the twentieth century, and now Chinese and Western craftsmen use flathead screwdrivers.

After all, there is only one slot in the screw head at this time.

Zhang Zhujing had already taken the flint and primer, and Zhang Chuxun took the flint and clamped it into the hammer and tightened the bolt on his mouth.

He poured primer into the fire door nest, and "Kakaka" pulled the hammer to the maximum position to be fired, and then pulled the trigger.

With a "pop" sound, the hammer flint struck down from the fire sickle, and the thick fire light and smoke rose instantly, and the fire was successful.

Minister Yang and the others all screamed excitedly, and Zhang Chuxun poured the primer in the Huomen Nest again, and fired again, and it was successful again.

He succeeded five times in a row, and then a satisfied smile appeared on his face.
