Everyone entered the temple again. Yang He thought about it and asked Yan Dezheng to bring his package.

He took out the pistol from it and said to Zhang Chuxun: "Can you look at this pistol?"

Zhang Chuxun took it and said, "What a gun."

He looked carefully and said, "It must be made by the master."

However, he looked at the fire door, frowned, and then skillfully pulled the hammer to the position to be fired, and then pulled the plate machine.

"Ba, bha, bha." He tried several times, and finally shook his head: "The reed cannot be used, and it may be pulled away if it cannot be fired."

Zhang Chugong also took the pistol and watched it, tried to hit it several times, frowned and said, "The reed should have been Su Gang at first, but it was replaced by Fallen Steel."

Yang He said: "Is there a way?"

Zhang Chujing hesitated a little. Zhang Chuxun and his elder brother looked at each other, gritted their teeth, and said, "Yes, it just so happens that there is the corresponding steel on the villain."

He entered the backyard and didn't know where to search. Finally, he carefully took out a pack of things. After opening it, some steel strips and ingots inside were finely textured and emitted the shiny metallic light. It was particularly chaotic and had an anti-loosening appearance. It was obviously refining many times.

"The fourth brother, do you really want to use it? It's very expensive, and the eldest brother can't bear to use it on his bird gun."

Zhang Chujing muttered, his face full of reluctance, as if the naughty temper had started to get angry again.

Zhang Chugong glared at him, looked at the steel bars with some reluctance, and smiled at Yang He and said, "These Su steels were obtained by chance. They were originally used for drill bits, and my husband just wanted reeds, so he used some."

Minister Yang saw that Zhang Chujing's face was flushing red and seemed to be about to cry. He said in a muffled voice: "Is this steel expensive?"

Zhang Chugong caressed the steel material, his face full of care. He said, "Two years ago, this Sugang cost about five or three cents per pound, but now it costs six taels of silver, and there is no price for the market."

Everyone took a breath of air conditioning. This steel costs six taels of silver per pound, and it is priceless?

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

Yang He nodded. The price was as expected by him. This kind of tool steel has always been expensive. The good steel in the Ming Dynasty was rare, five or six taels of silver per pound. It was normal to have a market but not priced.

At the same time, he sighed in his heart that there is too little good steel, and things are precious because scarcity is expensive. Such steel cannot be afforded by ordinary people. Now the prices are high, so the purchasing power of silver has declined. If six taels of silver are in a peaceful and prosperous era, it will be converted into rice prices, and one pound of Sugang will be worth 3,000 yuan in the next generation, which can be said to be a sky-high price.

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

A small spring piece is related to a series of progress in technology, just like a fire hat is also a way of ignition. It looks no different from a flintlock rifle, but it is related to the progress of chemistry.

Without good steel as springs to improve ignition efficiency, no matter how good the flintlock rifle is, it is still left alone.

He saw that the three brothers Zhang Chugong looked full of cherishing expressions, and he was reluctant to leave. He knew the meaning of this good steel in their lives. He smiled and said, "This steel is extraordinary, so let it be reserved for later use."

Zhang Chugong made up his mind and said solemnly to Yang He: "Just join my husband and serve him wholeheartedly, why should you care about these things outside of your body?"

He said to Zhang Chujing, and Zhang Chuxun: "Second brother, fourth brother, start construction."

...

Zhang Chugong and the other two opened the fire. The three of them used charcoal. Then Zhang Chuxun put on an apron, walked to the stove skillfully, took tongs and scattered the charcoal inside. A red light appeared. It seemed that the fire was 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 Su steel and put it in the furnace. Then he watched the steel heat, braised and soft, and the color slowly changed.

He looked at it carefully, and there was no trace of shyness and professional expression on his pretty face.

Yang He nodded secretly. The ironwork is the most important thing. There is no thermometer at this time, and it is all judged based on the blacksmith's personal experience.

Many people have been unable to master the knowledge of this kind of time for many years.

Seeing the steel discolored to a certain extent, Zhang Chuxun clamped it out. Not only him, but Zhang Chugong and Zhang Chujing both swung their hammers together to beat them.

"Ding Ding Ding Ding..."

The dense hammering sounds, the three brothers came and went back and forth, greeting the steel.

Everyone next to them looked carefully, not daring to show off their atmosphere, as if they were enjoying the sound of steel of the music again.

When the hammer reaches a certain level, Zhang Chuxun inserts the steel material into the fire. When the heat arrives, he takes out the hammer and beats it again.

Generally, the material needs to be forged and burned several times before the embryo will come out, but this is just a rough embryo, and it will be completed through multiple processes such as quenching and fine grinding.

Especially quenching is a very technical process. When to quench and how long it takes to quench, it affects the quality of the finished product. Quenching technology also measures the skill of the blacksmith.

There are also various skillful use, control of hand strength, etc. Many iron-study apprentices have been studying for more than ten years before they can get a master. Almost all geniuses can get a master in three to five years.

It can be seen that the three brothers of Zhang Chugong are part of the genius. Zhang Chugong also told Yang He earlier that he and Zhang Chujing were not very good at firearms and other aspects. They mainly used to make refrigeration weapons, muskets, etc., and only swung hammers.

This was also the arrangement of their family, such as the eldest and second, the second, the sword, spear, arrow, etc., the third and fourth, and the fourth, the firearms were made.

In particular, his third brother Zhang Chuqian is an expert in the inner world. Zhang Chuxunyan's own skills are only half as good as those of his third brother.

but……

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

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

...

After several forgings, Zhang Chuxun's hand appeared in his hand with a squirrel and a thick embryo of the spring steel sheet. Then Zhang Chuxun carefully processed it on the anvil. He beat it very carefully, and then used a file to file some of the bumps and rough areas, and then quenched and polished.

Finally, these carefully crafted parts appeared in his hands.

Zhang Chuxun flicked the steel sheet with his fingers, and a satisfied expression appeared on his face. He used a screwdriver to unscrew the part of the gun and installed the steel sheet and the scythe and other parts. He matched them one by one. His technique was very skillful and he had a kind of focus charm.

Yang He saw that the screwdriver he used was a flat-line screwdriver. This kind of screwdriver is not easy to use and often destroys the screw grooves that are not strong in structure, making it impossible to screw out the screws.

However, plum blossom knives and ordinary Phillips screwdrivers did not appear until the 1930s. Now, Chinese and Western craftsmen use flat-line screwdrivers.

After all, only one slot is opened at this time.

Zhang Chujing had already taken the flint and the lead medicine. Zhang Chuxun took it and clamped the flint into the firing hammer and tightened the bolt on his mouth.

He poured inducing medicine on the fire door nest, pulled the hammer to the maximum position to be fired, and then pulled the plate machine.

With a "bang", the hammer flint hit the scythe and the thick flames rose up instantly, and the fire was successfully fired.

Minister Yang and others screamed in excitement. Zhang Chuxun poured the induction medicine into the Fire Gate Nest again and fired it again, and it was successful again.

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