The North Stygian Villa monopolizes the weapons casting industry in Dajing, and it is not enough to say that it is rich enough to rival the country, but it is definitely one of the best wealthy families in Dajing, so there are also casting furnaces in the North Styx Villa, as well as a group of skilled craftsmen, but it is more of a huge ore reserve in stock.

Qin Yuelou was picking and choosing in the warehouse, and he was also thinking in his head.

Qin Yuelou's body has the ability to transform into a universal power, but this soldier clone does not have it, so what the soldier clone can rely on is only a huge amount of knowledge.

Fortunately, the ore storage capacity of the North Stygian Mountain Villa is large, and it is also placed in different categories.

If you want to forge a sword that will not rust, according to the ancient times of the Dajing Dynasty, where the productivity was not developed, you can only start from the combination of casting materials.

As for blowing hair and breaking hair, this is simple, just use the soldier's ability to sharpen the blade.

Although Qin Yuelou needed to strike iron, he needed to make alloys according to the proportions.

Qin Yuelou chose copper and cassiterite, as well as refined lead, and a little iron.

Beiming Fengyun looked at what Qin Yuelou was doing, and he didn't know what Qin Yuelou wanted to do, he only saw Qin Yuelou burning charcoal, and then the woodstone was thrown into the charcoal. br>

After a short wait, some glittering liquid was burned, and it was tin.

Then the tin floated in the air, and then the copper was heated, which was also heated into copper juice, and the tin was poured with small amounts of lead and iron.

A puddle of molten metal liquid was supported by Qin Yuelou's ability as a soldier's clone, but from a distance, it looked as if it was floating in the air.

The alloy he made was bronze.

Four points of its gold and tin are one, which is called the Qi of the halberd; Three points of its gold and tin are one, which is called the Qi of the big blade

The "gold" referred to here refers to copper, that is, what Qin Yuelou created is bronze.

Bronze can be said to be the earliest alloy in the history of the previous life, after research, it is still a question of whether there is a bronze in this world, after all, he does not know about the earlier history, because there is no such detailed historical record in this world as in the previous life.

The reason why Qin Yuelou chose bronze is also because he thought of a sword weapon in his previous life, this sword weapon has been immortal for thousands of years, and the edge is still there when it is unearthed.

According to the data, this sword contains about 80~83% copper, 16~17% tin, and also contains a small amount of lead and iron.

It is very simple to reproduce the material of such a sword, it only needs to be melted and added, and the calculation power is still handy to deal with this metal ratio.

In fact, copper, as the main component of bronze swords, is an inactive metal, which is generally not easy to rust under normal temperature conditions, that is to say, under the same circumstances, bronze still has an advantage over iron when the sword is rusty.

Fortunately, the furnace of the Northern Stygian Wind and Cloud House is good, although it is not as good as the jamming method, but it can be regarded as being able to reach the melting point.

But at the same time, because of technical limitations, Qin Yuelou could not manufacture chromium salts for coating, so he could only simply manufacture bronze alloys.

But the hand that Qin Yuelou showed also made Beiming Fengyun look away in his heart, and he couldn't show any traces of strength in the air, not to mention that he couldn't see that there was a martial arts cultivation, and this hand could be said to be a foreign skill.

I saw that the bronze juice was cast by Qin Yuelou in the lifting with a huge amount of calculation, and with the help of spatial perception, the inside of the bronze juice was calculated.

Then, with the help of the power of space, it was used as a mold, and at the same time, the power of space was used to remove impurities and forge the gradually solidified bronze juice.

Let this gradually solidify bronze juice become more and more dense, dense means hard, but it also has to have toughness, so this density will not increase after reaching a suitable threshold.

A sword weapon that uses the power of space to hammer can be regarded as iron.

It is also as if space is used as a mold for stamping, and the sword edge is also used to open the edge with the power of space.

It didn't take long for

This bronze sword, which was about two feet long, fell into Qin Yuelou's hands, imitating the style of the eight-sided Han sword in the previous life, but it was also an integrated creation.

However, Qin Yuelou used his knowledge of aerodynamics to make some round holes in the sword.

The distribution of these round holes is to increase the speed of the sword, and the air pressure behind it will also form a thrust, so that the speed and strength of the sword can be increased.

Qin Yuelou held the sword horizontally in his hand and threw it to the Northern Darkness Wind Cloud at will.

"We'll have to see if it's rusty or not, but you can take a look at nitpicking first." Qin Yuelou stood with his hands in his hands, looking at the North Darkness.

It's just that Beiyin Fengyun didn't try it, but changed his enthusiastic face.

"It's really a human being who can't be seen, sir, your hand is really eye-opening, I don't know if Mr. has the intention to do things for my North Stygian Villa?"

It is estimated that he wanted to receive Qin Yuelou to build weapons for him, no matter what era it is placed in, the technology generated by knowledge is the core of promoting the development of various industries.

Only by liberating the productive forces can the times move forward, but it is the fast forward of the times produced by the convergence of countless wisdom, and before the convergence of wisdom, it is also caused by the accumulation of countless sedimentary heritage.

Qin Yuelou alone can't do it, although he can exchange a lot of knowledge to advance, but obviously, this kind of feudal dynasty will be happy to add some blockage to him.

So before he is invincible in the world, this kind of thing can only be beaten in the belly.

Qin Yuelou listened to the words of the Northern Darkness and laughed.

"No need, I already have something to belong to, your Northern Styx Mountain Villa obeys the orders of the imperial court, but our Qin Shi Mingyue Tower is not." Qin Yuelou made a fuss, and immediately cut straight to the point.

"I just came here this time to see the inside of the North Styx Villa, and by the way, I want to ask straight to the point, now the rumors of the hat demon in the North Styx City are all over the place, but no one has dealt with so many qi refiners in your North Styx Villa, and I dare to ask, are these qi refiners under your hands really capable? Or are they capable enough to confuse your hearing and make you think they have what they do? This thing is really a little incomprehensible,

After all, this hat demon rumor is infinitely poisonous."

Qin Yuelou asked with a gun and a stick, he didn't like to be polite, he asked directly, it didn't matter if he couldn't ask, he knew that he could telepathize.

"What hat demon rumors? Sir, how did you hear about it?"

He knew that Qin Yuelou sensed the inner thoughts of the Northern Underworld.

[What hat demon rumors? How did I not know? There are no demons mixed in the city, and besides, these group of qi refiners are all highly cultivated, if there are really demons, how can they not perceive it? 】

The Northern Underworld is also confused.

He knew that he could not fake the heart and the emotions he felt.

Maybe you can deceive people on the surface, but you can't on the inside.

Now it was Qin Yuelou's turn to be dumbfounded.

"What's that?" You're not behind it? Artificial demons, you and the Qi refiners in your villa don't know?"

"What's behind that? What man-made demons? What the hell are you talking about, sir?"

[What artificial demons? What is behind this? What the hell is he talking about? He was still extremely puzzled by the perception of the Northern Underworld.

Qin Yuelou sighed, and then activated his mind to delete this memory from the minds of the Northern Darkness Wind Cloud and the Northern Darkness Xiaoxue.

The North Stygian Storm didn't know about the hat demon in the city.

Looks like we'll have to catch one at night.
