During the Shang and Zhou dynasties, it was common to use qingщww{][lā}

From the Warring States period to the early years of the Eastern Han Dynasty, the use of iron began to become widespread and became the most important metal. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Compared to bronze, iron is several times harder than bronze.

When Su Yuan was in Sanshanguan, he found the iron ore in the mountain, so although he left Sanshanguan, he asked Deng Jiugong to help collect the iron ore, and then transported it to Yanshan.

Later, when he came to Yanshan, Su Yuan immediately ordered Hei Niu to invite Chaoge's craftsmen to Yanshan and began refining iron ore.

Now the army has arrived at Jiameng Pass, and the craftsmen are also marching with the army.

Su Yuan didn't show up a few days ago, and it was he who led the craftsmen to hurry up and refine iron ore.

Looking at the black iron rod that Hei Niu was holding in his hand, Zheng Lun immediately shook his head and said, "What is this thing, what can it be used for." ”

Su Yuan smiled slightly and said, "Zheng Lun, you try to smash this piece of iron with a weapon." ”

The black bull immediately lifted the black iron and stretched it out in front of him.

Zheng Lun was puzzled: "Big brother, my demon pestle is made of extraterrestrial divine iron, and ordinary weapons can be broken with just one smash." This thing in the black bull's hand is only afraid that I can't smash it. ”

Su Yuan didn't speak, just waved his hand, meaning to let Zheng Lun try his best.

Zheng Lun raised the Demon Descending Pestle, but he still said uneasily: "Black Bull, be careful, don't let my Demon Descending Pestle hurt." ”

The black bull smiled slightly and said, "You can come as well." ”

Zheng Lun raised the demon slaying pestle and struck at the iron rod in the black bull's hand.

I only heard the sound of the "bell", only to see sparks flying everywhere, and the demon pestle was bounced back, but the iron rod in the black bull's hand was unharmed.

Seeing this, Zheng Lun couldn't help but be overjoyed, and asked Su Yuan, "Big brother, have you appeared in the Outer Heavens Meteorite?"

Su Yuan shook his head and said, "Why is it outside the sky, it's just everywhere on the ground." At that time, although it is not guaranteed that each person will have one iron tool in his hand and create three or five thousand pieces, it will not be a problem. ”

"Three or five thousand pieces?" Zheng Lun was immediately dumbfounded.

"However, the precision of this iron tool is not pure, and I am afraid that the fire will not be enough. Looking at the stove in front of him, Su Yuan thought for a moment, and then patted the jade pixiu on his waist, only to see a glass lamp appear in Su Yuan's hand.

"Ma Shan, come out. ”

With Su Yuan's words, he saw the glass light flashing, and the lamp fell to the ground, turning into Ma Shan.

Su Yuan pointed to the furnace in front of him and said, "Increase the temperature of the flame." ”

Ma Shan immediately nodded and plunged into the furnace.

I saw the flames in the furnace suddenly rise, and the flames took on a faint purple color.

The purple flame indicates that the temperature has reached 3,000 degrees, which is exactly the temperature needed to purify iron ore.

"Black Bull, keep striking this iron rod, and you will beat me out all the impurities in the iron rod. ”

"Understood!" the black bull immediately took off his shirt, went into battle shirtless, burned the iron rod red, raised the sledgehammer in his hand and struck it continuously.

I only heard the sound of "bells" constantly sounding, and under the flames, the black bull was sweating profusely, and his whole body was reflected red.

Under the continuous blows, I saw that the iron rod in the black bull's hand was getting smaller and brighter.

However, the Black Bull's sledgehammer is also made of bronze, and it simply cannot withstand the 3,000-degree heat in the furnace.

Therefore, after a short blow, the black bull could only replace the sledgehammer, and after breaking seven or eight sledgehammers, the black bull saw the black bull put the iron rod into the river water beside him.

With the sound of "stabbing", a white gas came out, and the red iron rod gradually faded to red and slowly turned silver.

When the red color completely faded, the black bull took out the iron rod, and saw that in the black bull's hand, it was an iron sword that flowed silver and was as thin as a piece of paper.

Seeing such a thin iron sword, Zheng Lun couldn't help but wonder: "Isn't it so thin that it will break when it is smashed?"

Su Yuan smiled slightly and said, "Black Bull, you stand on the ground with an iron sword and smash it with a sledgehammer. ”

"Understood. ”

The black bull immediately raised the blade of the iron sword, made the craftsman hold it up, and raised the sledgehammer in his hand.

But looking at the iron sword as thin as a piece of paper, the black bull raised the hammer and hesitated a little.

"Big brother, it's not going to be broken, is it?"

"Smash. ”

With Su Yuan's order, the black bull only closed his eyes and dropped the sledgehammer fiercely.

I only heard the sound of "stabbing", and I saw the sledgehammer falling straight down, and it actually crossed the iron sword directly.

Seeing this, the black bull immediately felt heartache and said, "It's broken, it seems to be broken." ”

But as soon as the black bull's words fell, I saw that the sledgehammer in his hand "plopped", and it was divided into two pieces and fell to the ground respectively.

I saw that the surface of the sledgehammer was smooth, and it was cut off.

When I looked at the iron sword again, not only was it intact, but the blade was still extremely sharp.

Seeing this, the black bull grabbed the iron sword, held it in front of him in disbelief, and exclaimed excitedly: "Artifact, it's really an artifact." ”

With that, the black bull swung his iron sword again and again, slashing at the sledgehammers around him.

I saw that the sledgehammer with a thick handle was like paper paste under the iron sword, and it turned into two pieces with a single split.

At this moment, Zheng Lun's body immediately shook, and the craftsmen around him were also shocked.

For a while, I saw that the craftsmen around him knelt down one after another, and bowed to the black bull: "Divine craftsman, divine craftsman!"

Only craftsmen who can create artifacts can block the name of the craftsman.

The black bull held the iron sword in his hand, and his body was already trembling with excitement.

"Big brother, am I really built it?"

Su Yuan smiled slightly and said, "Not bad." But that's just the beginning. Iron swords, iron spears, iron shields, iron horseshoes, black bulls, these must all be completed within a month. ”

"Understood, big brother. Black Bull immediately agreed.

"However, before you can build these, you can build a hammer yourself. ”

Looking at the hammer that was all shattered into two pieces around him, Su Yuan smiled faintly.

From this day on, the black bull was like a crazy demon and immediately began to build.

The first weapon he built was the hammer.

This hammer was the first to be built, but it was also the last to be completed.

Because every iron sword is forged by this iron hammer.

Three thousand forges can make an iron sword, but the Black Bull's hammer has been tempered tens of thousands of times.

The number of times all iron swords are forged together, which is exactly the same number of times that this iron hammer is forged.

A month later, when the camp was full of iron, the black bull rested for the first time.

When he looked at the hammer in his hand again, he saw a flash of brilliance on the black hammer, which only an artifact can have.
