"Chief?"

Wei was shocked when he saw Yang Hao, and hurriedly bowed: "Wei meets the leader!" ”

Yang Hao hurriedly helped him up and said with a smile: "No need to be polite, you make it easy for me to find it." ”

Wei was puzzled: "Why did the leader come here, just send someone to call me back, bother the leader to come over in person, Wei is really a capital crime." ”

Yang Hao said: "It's okay, I still have to ask you, how did you come to the mine in person, a master craftsman." ”

Asking Yang Hao, Wei said excitedly: "Back to the leader, I have tried out the method of mixing copper and tin mixed metals. ”

When Yang Hao heard this, his spirit was suddenly shocked, "This is true." ”

Wei Dao: "Wei is absolutely right, thanks to the method given by the leader, I and a few workers tried for several days in a row, tried every ratio, and asked two officials from the officials to calculate the calculations, and recorded the properties of various mixed metals, and planned to report this matter to the leader after a while." ”

"Well, that's great, the metal still works."

Yang Hao hurriedly asked.

Wei nodded and said: "It's not just usable, it's just amazing, I've been refining copper for so long, and I've never seen such tough gold." ”

"Now that the results are out, why don't you report them to me in time."

Yang Hao was a little dissatisfied.

Wei Dao: "The chief's atonement is really a discovery by his subordinates. ”

Yang Hao frowned and said, "What did you find." ”

"When I was smelting metal, I found that the gray-white thing was actually two different things, and the melting situation was different depending on the heat, but this difference was very weak, and I couldn't distinguish between these two different metals, and I didn't know which one would affect the properties of mixed copper."

Wei frowned.

After Yang Hao listened, he also touched his chin and thought about it.

It's just that in his impression, bronze is copper-tin alloy, and he hasn't heard of anything else.

At this time, Yang Hao once again realized that he hated less when the book was used, and if he had worked hard to become a scholar, he would not have scratched his ears and cheeks like he does now.

Unable to think of a reason, Yang Hao asked, "Then why are you here?" ”

"According to the miners, the white metal is the most common in this area, and I couldn't wait for the ore to be shipped back, so I simply came here myself."

Wei replied.

"What did you find?"

Wei Wenyan, squatting down, rummaging in a small back basket for a while, took out a gray-white stone with a lot of impurities.

"This piece of ore has the most white metal content I've ever found today."

Yang Hao took the ore, the fist-sized ore was very heavy, even if Yang Hao's body was very strong now, it was still a little difficult to hold it.

"How can it be so heavy?"

I was a little puzzled in my heart, and suddenly a flash of inspiration flashed in my mind, and I thought of a possible nature.

"Have you ever separated these two metals and weighed them apart?"

Wei shook his head and said, "I haven't found a way to separate these two metals, how can I weigh them." ”

When Yang Hao heard this, he smiled and said, "I forgot about it." ”

Wei Qi said: "Boss, have you seen something?" ”

Yang Hao nodded and said, "There is a guess, but I can't be sure, in this way, you go back with me first, and let's study it together." ”

As a rare technomaniac in this era, Wei immediately became excited when he heard this, and said with a basket on his back: "Leader, please, I'll lead the way in front." ”

Looking at Wei Wei, who was already middle-aged, walking fast, Yang Hao couldn't help but smile.

"That's the attitude you should have when doing research, and that's good."

The broken road and carriage were difficult to travel, so Yang Hao and the others walked back to the copper smelting workshop.

Back at the workshop, Wei couldn't wait to clear out a furnace.

Although Yang Hao also wanted to verify his guess, he wanted to see the test results.

Trials are important, but the finished product and the test data are what are needed the most.

Yang Hao asked Wei Xian not to be busy separating the tin, and asked him to bring the finished product and data.

Wei also realized that he was too excited, and repeatedly confessed, and ordered someone to bring over what he had made.

Soon a worker came over with a basket woven of bamboo strips, which contained a bunch of daggers of different sizes and colors, which did not have sword hilts, and Yang Hao guessed that they were all for experimentation.

Picking up a dagger at random, I saw a square Arabic numeral 6 engraved on the blade of the sword.

"What does that number mean?"

Yang Hao asked.

"In order not to be confused, I engraved numbers on the tin daggers with different weights to distinguish them, and the number 6 means that tin accounts for sixty percent."

Wei replied.

Yang Hao nodded, put down the dagger and said, "Show me the record." ”

Wei Wenyan hurriedly handed over a roll of bamboo slips.

Yang Hao unfolded the bamboo slip, looked at the twisted and crooked text on it, and couldn't help frowning, and even guessed before he understood the test data report.

"Tin two, copper eight, tough, tin four, copper six tough, not easy to break。。。。。"

After Yang Hao finished reading it, he put away the bamboo slip, picked up the dagger just now, looked around, picked up a branch, and stabbed it down.

The tip of the blade pierced into the branch for about a centimeter, Yang Hao pulled it out, looked at the edge carefully, and did not see the phenomenon of collapse, there were also any cracks, and nodded with satisfaction.

"Yes, that's the killing weapon."

Wei smiled: "With this kind of metal, my Daqi tribe will definitely be able to gain a foothold in this anointed land." ”

Yang Hao nodded and threw the dagger into the bamboo basket.

He hadn't tried the specific properties of these alloys one by one, and this one was enough, and he chose to trust the abilities of his subordinates.

"Pick out these metals that are suitable for killing, and start refining the spearhead and the tools I told you earlier, there is a shortage of manpower, so I will crane the manpower from the other side, and be sure to make the farm tools before the beginning of spring, and the metal spearhead will be at least more than three hundred."

Wei nodded and said, "Don't worry, chief, as long as there are enough people, I will definitely be able to complete it." ”

Yang Hao said in a deep voice: "Wei listens to the order!" ”

When Wei heard this, his face turned pale, and he hurriedly bowed: "Subordinates listen to orders!" ”

"Now I have appointed you as a worker, in charge of all the construction and production matters of the tribe, and your status is equal to that of households and officials."

Wei stood on the spot, barely believing his ears, and his mouth grew so big that he could almost stuff a grid of eggs into it.

"What, don't you accept it?"

Yang Hao asked.

When Wei heard this, he was pleasantly surprised: "Wei listens to the order!" Thank you, Chief, for the reward! ”

Yang Hao nodded and said: "One thing, the responsibility is heavy, you must not slack off, you not only have to consider the construction of the matter, but also to cultivate more craftsmen like you for the tribe, only more talented people appear, in order to make our clan stronger." ”
