After many days, Deep Water Bay has been given a makeover.

From the original secluded small sea mouth, it has been transformed into a large pier full of people.

In addition to the people of the small fishing village, there are many villagers from other places who have settled here, and the surrounding fishermen have also come here to fish, especially after the pirates in the golden sand beach, the big guys are afraid that the pirates will go ashore again, and they all run to Qinzhen, so that the deep water bay once surpassed the golden sand beach and became the most popular Haikou within a radius of hundreds of miles.

Looking at the fishermen who cast their nets to fish, the sparkling sea shone brightly under the sun, making Zhang Luo, who had never seen the sea, yearn for it in his heart.

Compared with his hometown, which has been in chaos, the coastal county in front of him is even more prosperous and peaceful.

"Benefactor, you're here!"

Li Erniu jumped off the boat and ran in front of Qin Zhen.

"Erniu, this is Zhang Luo, I am working with you for the time being." Qin Zhen briefly introduced: "Lao Zhang, this is Erniu, our own people, if there is anything, just open your mouth, don't be polite." ”

After a brief greeting, the fishermen's horns sounded on the beach.

Dozens or hundreds of topless fishermen work together to pull long ropes and drag their nets out of the water.

"Thousands?"

Zhang Luo raised his eyebrows slightly, as if he saw something interesting, and hurriedly walked over.

"You know this thing?" Qin Zhen said curiously.

"The craftsmanship of Shenshu is not known, but it can only be said that it has been seen." Zhang Luo stroked the fishing net and couldn't help but be surprised: "The texture is slightly cool, the hardness is moderate, the person who makes this thousand pieces of silk is a good hand!" Qianren silk has excellent toughness and is indeed suitable for making fishing nets, where did this fishing net come from? ”

"I did." Qin Zhen said with a smile.

"You did it?" Zhang Luo was shocked.

"To be precise, I knitted this fishing net, and I bought this thousand silks."

Hearing this, Zhang Luo carefully looked at the fishing net, and couldn't help but praise: "The workmanship is indeed ingenious, and the relaxation is moderate, I don't see many people with whimsical ideas like you in this world." ”

He paused, and said: "It's just that this thousand silks, after all, are textile things, the bearing is limited, at most one thousand catties will reach the upper limit, if you can use fine iron to weave a net, the effect must be better than this thousand silk, maybe you can catch tens of thousands of pounds of fish." ”

"Can you do it?" Qin Zhen came to the spirit.

"It should work, but tools are needed." Zhang Luo shrugged.

These words made Qin Zhen full of curiosity about Zhang Luo's smelting technology.

He really wanted to know what kind of amazing craftsmanship this man in front of him had!

Qin Zhen secretly swore that when Lin San came back, he would definitely complete the relevant items of the blacksmith shop and let Zhang Luo start work directly!

"That's right."

Qin Zhen seemed to remember something, and his eyes immediately became hot.

Since this piece can even be pounded out of iron wire, what about the finer iron tools?

Like what...... Barrel, firing pin ?!

As we all know, one nitrate, two sulfur and three charcoal are the basis for the production of gunpowder, but if you want to use this thing reasonably and reliably in the military, you need certain smelting technology.

Black powder originated in the Tang Dynasty, flourished in the Song Dynasty, and was set in the Ming Dynasty.

Before the Song Dynasty, it was extremely difficult for people to control the power of gunpowder, and it was mostly used in folk fireworks or alchemists; After the Song Dynasty, with the development of social technology, especially the improvement of smelting technology, the promotion of coal ironmaking allowed craftsmen at that time to produce higher quality fine iron, which constituted the constituent conditions for the development of "thermal weapons" at the beginning.

Prior to this, the military generals of the Northern Song Dynasty tied gunpowder to iron arrows and fired them, and the handcuffs were still held with bamboo barrels.

The power is worrying.

In the Southern Song Dynasty, gunpowder techniques became more and more advanced, and the first "tubular firearms" appeared, bamboo pipes were replaced by more sophisticated iron pipes and copper pipes, and the sub-kiln was made of iron and other substances (similar to bullets) and then gunpowder used the tension of blasting to cavulate the faders, which was the prototype of later rifles and bullets.

Unfortunately, in the course of the war against the Song, the Jin and Mongols also learned how to use and make firearms, which contributed greatly to the Mongol cavalry almost the entire Eurasian version.

After the Ming Dynasty, with the improvement of the steel filling method and the emergence of Sugang, the craftsmen at that time could make more powerful barrels - that is, cannon barrels, and red-coated cannons became the mainstream.

Qin Zhen has read a lot of historical novels, and the people in them can easily make high-stability firecrackers and cannons.

This doesn't make sense.

Black powder and firearms are actually two completely different concepts, the former only requires one sulfur, two nitrate and three charcoal, while the latter requires more advanced iron smelting and forging technology.

Qin Zhen didn't know whether the forging process of this world could support the necessary parts needed to produce firearms, but judging from the craftsmanship that a craftsman could produce at the level of a thousand silks, there should still be some possibilities.

Facing Qin Zhen's expectant gaze, Zhang Luo hesitated slightly.

"It's fine for you to ask me to get a solid iron bar, but if you say that you want to hollow out the center of the iron bar, you have to make sure that the whole structure is roughly stable, and it can be connected to other things like tenons, I think you're here to find trouble."

He said angrily: "I am a blacksmith, not an immortal. ”

Hearing this, Qin Zhen couldn't help but be a little disappointed.

If he can make a firearm, he can make a big show and carry out a dimensionality reduction attack on this world.

But apparently, reality did not open this door to him.

"Listen to you, you have also studied iron smelting technology?" Zhang Luo said curiously.

From Qin Zhen's words, he could clearly feel that the young man in front of him understood some things, but he didn't seem to know much.

A doll in the countryside, where does it come from so many whimsical ideas?

"I just love to figure it out." Qin Zhen said with a smile.

Since the prospect of firearms manufacturing is worrisome, Qin Zhen can only think of ideas from the existing basis.

He handed the repeater over.

"Brother Zhang, look at this thing, can you make an iron one?"

"Crossbow? What did you do? ”

Zhang Luo was dumbfounded, and after playing with it a little, he deeply felt the ingenious workmanship of this thing, and tried to shoot only to find that this crossbow is very good in terms of accuracy, accuracy and strength! What shocked him the most was that this thing was actually fired in bursts!

It's a pity that the shooting range is shorter, only thirty steps, if it can reach two hundred steps, once the whole army is equipped, the army of the Great Shang will be invincible!

The more Zhang Luo looked at it, the more he couldn't put it down, and he couldn't help asking.

"Who did you learn carpentry work from?"

Qin Zhen scratched his head embarrassedly and said, "Hey! I just don't like to figure it out and figure it out myself. ”

"Genius! You're a fucking genius! Zhang Luo's breathing was suddenly short, he looked at Qin Zhen for a long time, and suddenly burst out with a sentence: "Are you interested in worshipping me as a teacher?" I'll teach you to strike iron! ”

"Huh?"
