- World Adventures drop limited artifacts, long-handled axes and heavy shields, all of which are left over from eight hundred years ago. The main tribes of Emperor Yan, some of which originated in the western regions during the Fuxi clan, The ancestral land of Xing Tianshi is near here.
Yan Zai lifted up this pair of weapons, and it was still stained with a lot of soil, as if it had just broken out from somewhere, and this kind of smelting technology in ancient times also surprised Yan Zai.
This pair of weapons is not an ordinary forging method. It contains two axes, one is short and the other is long. The casting process, and the long gold (copper) ax was cast by a lot of craftsmen gathered by Di Youshi, and the material used is also divine copper.
But even the divine copper will rust, and there is nothing in this world that can resist the power of time except mud and dust.
The weapon that is not broken for 800 years, Yu Zai knows it.
That is the Goujian Sword of the King of Yue. When this sword was unearthed, it has been 2,500 years since it was cast.
"The composition of axes and shields is mainly copper, followed by tin. To ensure that they will not rust for thousands of years, the first point is that the proportion of copper is 80%, and the proportion of tin is 16-10%. seven."
"The subsequent specific gravity is aluminum and nickel, and after that, there is a very small amount of iron and sulfur. These are insignificant impurities."
Yanzai was talking to himself, but Guangchengzi pricked up his ears.
He looked at Yan Zai, and listening to Yan Zai's words, he gradually narrowed his eyes with a very serious expression.
"During the process of tempering, the lead element was beaten out. On the outside of the big axe and the heavy shield, these black patterns and thick lines are all made of sulfur or sulfide, which chemically reacts with the metal on the surface. produced, these should be metallic 'chromium'."
"This is passivation."
On the side, Hong Chao touched the shield, while Guang Chengzi changed from "listening carefully" to "thoughtful".
He looked at the concubine, then at the pair of weapons, and tugged at his beard.
The ancient bronze wares are mainly a binary alloy of copper and tin. In "Zhou Li ¡¤ Kao Gong Ji", there is a saying that "four parts are gold (copper), and tin is one part, which is called Ge Ji Qi; three parts are gold And Xi Juyi is called the Qi of the Great Blade".
"Different weapons have different requirements for binary alloys. Swords, axes, and spears have different casting requirements for different parts of weapons, and the ratio of binary alloys is also different. Where bending is required, the proportion of tin should be reduced. If you want strength and sharpness, increase its ratio, and only the smelter knows this ratio"
"In the era of Shennong, how could there be such a superb metallurgy technology!"
Metal discrimination is also Yan Zai's housekeeping skill. If you don't have this ability, you can't be the captain of the exploration team. The smelting technology of the pair of shields in front of you shocked Yan Zai.
Although it is said that this thing is only about sharpness, it may not be as powerful as the iron weapon with increasingly mature technology, but this thing is an axe, not a sword, and the requirements for sharpness are not high. On the contrary, the comparison of comprehensive performance is this The set of ax and shield is a complete victory.
Just like an iron sword has 10 points of attack and 10 points of armor penetration, this big ax only has 8 points of attack, but it has critical strike, armor penetration and percentage damage!
Moreover, the durability, firmness, resistance, heavy hit, stun and other attributes of the ironware that can be cast now, except for the swing speed, other attributes, all current ironware are far inferior to this stuff.
This is an ancient miracle, the crystallization of the painstaking efforts of ancient gods.
In the back, the way Guangchengzi looked at Yuzai had changed.
Those words of Yan Zai gave Guang Chengzi a lot of inspiration, and if before, Guang Chengzi's first impression of Yan Zai was Chisongzi's melon-eating apprentice, and his second impression was Shennong's genius descendant, then Impressions now
This kid actually knows so much about Jin Tieyezao?
I didn't even understand that
Guang Chengzi tugged at his beard.
Are young people nowadays all fashionable to pretend to be low-key?
Although many of the words that Yu Zai said were talking to himself, and with syllables and vocabulary that did not belong to this era, but who is Teacher Guangchengzi? He has lived for 1,500 years. Heard ithe translated it in his head directly according to his own understanding.
Direct machine flip, two dragons playing with pearls, Guangchengzi beat Chisongzi to the ground!
Yan Zai squeezed a little bit of the white clay on it with his fingers. There is very little clay, but it really exists.?
"Its preservation must be placed in a heavy wooden shell, buried several meters deep in the ground, and then layered with stones. Between the gaps, it may be a washed, fine-textured stone. It is filled with white clay, which is called white plaster mud, and it has high density."
"Under the deep mountain soil, in the stone mounds and big hills, so many sealing layers basically cut off the air exchange with the outside world, without the flow of air from heaven and earth, the corrosion process of copper and iron is greatly reduced. The reduction is like freezing the years"
Who is the maker of this pair of weapons?
Just as Yu Zai was thinking, Guang Chengzi, who had been listening for a long time, found that there were no lessons at all, so he stepped forward and thoroughly touched the pair of weapons from top to bottom.
"Boy, you know a lot about things like gold and copper. Your ancestor Shennong grew up eating herbs, and you grew up eating stones, right?"
Guang Chengzi asked Yuzai very seriously.
Kid, did your teeth choke when you ate rocks?
Shennong eats hundreds of herbs and eats heartbroken grass. Sooner or later, you have to eat hundreds of stones to eat uranium ore, and then directly mutate the human body Shennong has two surnames. It is also called Yiqi because it has settled in Yi and Qi successively.
Well then, your ancestor was called Yiqi, so you should be called Ivan.
And the structure of this axe, and even its caster, Guang Chengzi also told Yuzai!
"If you're not mistaken, this casting method should be cast by a master craftsman of the Bu Sui family."
?Busui (southwest of Shandong), also known as Fusui, was a tribal alliance during the Shennong period, which was composed of the Bu and Sui tribes, and the Sui tribe was not the Suiren clan.
They used to be the enemies of Shennong. Before Shennong unified the world, the axe did not surrender, so Shennong attacked the axe. The axe was good at making axe weapons. ) tribe, marched along the ancient Onozawa and crossed the river to defeat the Sui tribe.
Guang Chengzi quickly sent out a solicitation to Yan Zai:
"Boy, I think you have the talent to be a craftsman! To be a qualified swordsman, you must first learn to identify the fine gold and copper. You have more knowledge reserves than me. It can be seen that you have the ability. Don't worry. Follow the red pine nuts, follow me!"
Guang Chengzi made a big promise, saying that this weapon of yours, when I recover my mana, let me help you upgrade and strengthen it again!
Yan Zai was overjoyed, and immediately began to flatter, but Guang Chengzi looked serious, and for the first time rejected Yan Zai's flattery.
"Although you praise me so much, I won't appreciate it, because the things you praise are all noble qualities that I already have! You are just telling the truth. People must learn to praise others. You can¡¯t always tell the truth, understand.¡±
Contains: "(Muffling¡ª¡ª) (Muffling¡ª¡ª)"
Guang Chengzi said seriously: "I'll help you re-smelt the 'Qian Qi', but you also have to tell me everything you know, such as chemical reactions and alloy casting!"
"Don't think that I don't understand, I understand everything. In the past, I also forged many utensils for my tribe. I am a great craftsman in ancient times! Although the tinkerer has the skill of stealing the magic, But in my eyes, there are still shortcomings!"
"I'm just going to show you that it's not a skill for someone to steal a god's work, but if I want to take it, it's a work of nature!"
Yan Zai suddenly lifted his spirits!
Technology, [Metal Casting] has been unlocked!
Allows you to build workshops and forges!
