Yang Hao took it to the copper smelting site, but saw Wei Zheng squatting on the ground and watching something intently, Yang Hao stopped the communication of the rest of the people, and walked over slowly.

I saw Wei holding two swords and staring solemnly with a solemn face.

"What's the secret of these two daggers?"

Yang Hao's sudden appearance startled Wei Yi, and the two short swords in his hands fell to the ground with a clear sound.

"Meet the Leader!"

Yang Hao smiled: "Excuse me!" ”

"Thank you, Chief!"

Yang Hao bent down to pick up the two short swords, and after taking a closer look, he found that there were some slight differences in the colors of the two short swords, and smiled: "You added something else when you cast the sword." ”

Wei nodded and said: "Since the leader said that day, the subordinates have recalled for a long time, and I feel that what the leader said is very reasonable, a few days ago, I found some gray-white things from the ore transported back, I mixed it with copper after smelting, and it really had a great impact on the texture of copper, and these two short swords were made of white ore with different weights.

”

Saying that, Wei pointed to the short sword on Yang Hao's left hand and said: "Like this handle, although it is tough, it is easy to break, and the other handle is a little soft." ”

Yang Hao nodded, knowing that this was the effect of the different proportions of copper and tin.

Although he knew that the main metal of bronze was copper tin, he did not know what kind of performance changes the various proportions would cause to this alloy.

"What's the yield of those white things?"

Wei replied: "Very little, not as much as copper." ”

"Take me to see it!"

"Chief, please!"

While speaking, under the leadership of Wei, Yang Hao came to an open space, only to see that there were many gray-white ores piled up here.

"These are the things that I ordered to be separated from the copper ore in the past two days."

Yang Hao looked at the large pile of pale yellow copper ore next to him, and then looked at the white ore, and couldn't help frowning, compared with the output of copper ore, the output of tin is really a little low, almost reaching the level of thirty or forty to one.

But fortunately, he now has a vein, and he only needs to work harder, and the tin production can make up for the need.

"Those craftsmen of the original Sanshu still listen to your orders, but there are signs of not helping"

Wei nodded and said: "The rewards given by the leader to those craftsmen are all according to the army, and they are too late to be grateful, how dare they slack off." ”

Yang Hao said: "That's good, those craftsmen have some skills, they must be used well, find a warm place, and I'll show you a few things." ”

Wei had already noticed the rolls of animal skins under Yang Hao's armpits, and knew that Yang Hao must have some unbelievable thoughts, and seeing that Yang Hao finally mentioned this, he hurriedly led Yang Hao to his residence at the construction site.

Wei's residence was just a simple thatched hut, no kang was built, only a charcoal fire was burned in a clay pot, although it was not cold, it was not warm.

Yang Hao looked at this simple residence and said in a deep voice: "This place is too simple, I will send it over tomorrow to build a row of houses here for you to live in." ”

Wei hurriedly said: "The leader doesn't have to be like this, it's enough for me to have a place to live." ”

"How can this be done, the craftsman is an important position in the clan, and it must not be damaged, let you live in such an environment, won't it make the world laugh at me for not knowing people?"

Yang Hao attached so much importance to craftsmen, Wei Wenyan was moved in his heart, and said: "It is Wei Zhi's luck to be able to serve the leader. ”

"Okay, let's not talk about that, I have something important to do with you this time."

After the two sat down by the brazier, Yang Hao unfolded a roll of animal skins.

Wei stared intently at the strange pictures on the animal skins, his face solemn.

"What do you see?"

Wei Shen said: "I have never seen the thing painted by the leader before, but this thing looks like a Rong and a stone axe, which is quite strange, and I can't see what it is." ”

Yang Hao smiled: "This is indeed an axe, but it is not the axe that is currently known, the things painted on this animal skin are all necessary things for craftsmen, such as this axe, its blade can be chopped, its back can be smashed, all made of copper and tin gold." ”

Wei exclaimed: "All made of copper and tin gold? This copper thing is feasible to cast soldiers, but if it is done as a chopping thing, I am afraid it is not appropriate. ”

Yang Hao said: "I think you can give it a try, today you also said that the performance of copper and tin is different, all because of the different components of copper and tin, as long as you find different components of copper and tin, the impact on the gold obtained, there will be gains." ”

Wei pondered for a moment and said, "If you can really get something, you can try this thing." ”

"Dare to ask the leader what the rest is."

Yang Hao said: "This first tool is called a saw, which is a thing for cutting wooden boards, and I have gained from looking at the edge of grass blades. ”

"Blades of grass?"

Yang Hao said: "There are small thorns on the edge of the blade of grass, and if people are careless, they will be cut through the skin. ”

Wei looked at the sawtooth in the painting thoughtfully, and said in surprise: "Amazing! Amazing! ”

As Yang Hao introduced all the carpentry tools, Wei was already numb, and he couldn't think of any words to use to describe Yang Hao's creativity.

Seeing Wei's eyes blank and dumbfounded, Yang Hao said, "Do you understand what I said?" ”

Wei came back to his senses, swallowed his saliva, and said again and again: "These are really divine soldiers, the talents of the leader, I can only look up!" ”

Yang Hao was not ashamed of his plagiarism, and said with a smile: "A little little Doyle, a person's power is limited, I can only provide an idea, whether it can be made depends on you." ”

"Rest assured, the leader, these drawings are already so detailed, if I can't make them, I will really be no different from the stupid dolphin in that circle, and I will live in the world without shame."

Wei said ashamedly.

Yang Hao smiled: "This is serious, if you want to make this, you need to determine the texture of the copper and tin gold, I will give you a way." ”

He looked left and right as he spoke, and said: "Take this clay pot as an example, its weight is a weight, I will set this pot as a catty, and if the weight of the rest of the things is equal to it, it will also be a catty, so that the weight of copper and tin can be determined." ”

Wei sighed: "Wonderful, wonderful, so it's a lot simpler, and there is a lot to be found." ”

Yang Hao said: "You have learned the method of arithmetic." ”

Wei nodded and said, "I learned some from Hu, and I have a little understanding of the method of addition and subtraction." ”

When Yang Hao heard this, he tested Yibanwei's mathematical ability, but the result was very disappointing.

Wei didn't say much, he really just understood something, and the degree of understanding was that the addition and subtraction within ten still had to be counted with his fingers.

This made Yang Hao feel a black line in his head, and this feeling was like wanting to cook, and it was as annoying as he found that all the ingredients were ready, but there was no fire.
