Jiu Yao frowned, observed for a long time, pouted and said:

"God, what did you let you do? It looks like the pottery caves that can be found everywhere on the plains, so do you want to fire pottery here? We don't lack this! Besides, the enemy is ...... now."

Lin Yuan didn't seem to listen, he carefully circled around the blast furnace a few times, nodding his head constantly, and seemed to be very satisfied with Hou Yi's craftsmanship. Pen & Fun & Pavilion www.biquge.info

"I ...... Not bad! Hou Yi, you really did it according to my drawings! Is there that dark groove in it? It's here, there should be a slot......"

"It's done! Yan Wang, the inside is exactly as you asked, we used only a little clay to make the shape you asked for in it, and then roasted it with firewood, and now it is all hard pottery. ”

Lin Yuan nodded vigorously, and suddenly, Jiu Yao seemed to have something, and she said:

"God-given!! I'm talking to you, what the hell are you doing? The Luohe clan immediately called Jiu Yao, but you didn't go to strengthen the fortress, you will go to find the stone of the gods for a while, and make this pottery kiln for a while, what are you going to do? You know, my sister and I have entrusted the lives of our entire clan to you! ”

Lin Yuan smiled faintly, looked back at Jiu Yao, and said earnestly:

"Sister Yao, don't worry, I'm just trying to find a way to defeat the Luohe clan now......"

"How to beat? With sacrifices? Prayer? Or your clay pots?!! Jiu Yao said with some puffiness.

Lin Yuan gently stroked the blast furnace and said in a low voice:

"Nope! I will arm our warriors with sharp weapons, and I will give them the strength to slay our enemies! ”

Jiu Yao was suddenly stunned, she suddenly thought that the man in front of her was definitely not ordinary, in the past few years with him, the other party had almost never done anything wrong, and what he said would definitely be realized......

So what kind of medicine is this heavenly gift sold in the gourd?

Jiu Yao sighed, so far, she has no better way, she can only hope for a miracle.

"Excellent! Hou Yi, you really lived up to my expectations! Not bad! ”

Lin Yuan praised Hou Yi a lot.

Although Hou Yi usually has shortcomings, he will definitely support and obey Lin Yuan's orders unreservedly, which is just what Lin Yuan values him most.

"Now, there's one more thing to prepare......"

Lin Yuan turned his head and said a few words to Hou Yi, who immediately nodded and left.

Then Lin Yuan gently touched Jiu Yao's head, looked at the other party with a slight smile, and the kind of confidence revealed between his eyebrows made Jiu Yao can't help but think about nothing......

……

The afternoon passed quickly, and the female warriors on the West Valley side also brought good news, they successfully chiseled a piece of fragment from the stone of the gods with granite axes, the process was very difficult, it is said that they smashed more than a dozen stone axes, but in the end, they still completed the task assigned by Lin Yuan, and dragged a meteorite block the size of a wild boar to Lin Yuan.

Lin Yuan took a closer look, there were about 80% of the blue ribbons on this stone, which looked like rusty ground glass, Lin Yuan knew in his heart that these were rare natural monomer copper that existed in nature, which meant that this stone could refine about 80% of the metallic copper at most.

Looking at such a large piece of ore in front of him, Lin Yuan couldn't help but nodded, he was very satisfied, about 80% of the copper was basically enough......

"King Yan!!" Hou Yi panted and ran from a distance, he wiped the sweat from his head, and his face was smoky and dark.

"King Yan! That one...... The charcoal you want...... I'm done! ”

It turned out that what Lin Yuan had arranged for Hou Yi before was to let him make some charcoal, because Lin Yuan knew that according to the previous way of burning firewood, there was basically no problem in baking pottery, but if you want to smelt metal, the temperature must be at least hundreds of degrees or more, and traditional firewood, with the help of a blast furnace in time, will not reach that temperature in any case.

Therefore, when no coal was found, charcoal became the only combustible material that Lin Yuan could use.

Lin Yuan followed Hou Yi to a place not far from the blast furnace, and he was satisfied to see that Hou Yi once again made the best place to bake charcoal according to his own design.

It was a cone-shaped object made of tree branches, covered with dirt, and at the very top of the cone, there was a small opening, from which puffs of smoke were rising.

"King Yan, according to your request, I built this shelf with bamboo and tree trunks, and then lit a bunch of leaves inside, and finally covered the outside with clay, so that smoke could only come out from above...... But this one can really make ...... The thing you were talking about? Hou Yi said with some hesitation.

Lin Yuan nodded, he had seen a video in the 21st century before, which was the survival video of the Australian brother at station B, which mentioned that charcoal was refined in this way.

"How long has it been missing?" Lin Yuan asked.

"Well, it's been a long time...... At first, the smoke was still strong, but now it seems to be almost gone......" Hou Yi said.

Lin Yuan nodded, which means that the charcoal has basically been made.

Then he walked over and kicked the cone so hard that it kicked the mud pile out of a large hole, and a strong smell of charcoal smoke wafted out.

It's done!

Lin Yuan's happy commander completely peeled off the cone, and after the temperature dropped a bit, a large pile of pitch-black completely carbonized tree trunks turned out inside, these were the charcoal he wanted.

He ignored the stunned crowd and ordered directly:

"Hou Yi! Do you remember the process of making it? Now, all of you, except for the necessary patrol personnel, all of you will come and cooperate with your work...... Hou Yi, I want you to arrange people to make charcoal in this way day and night from now on! The more the merrier! Do you understand? ”

Hou Yi nodded hurriedly, and immediately ran away to carry out the order.

Lin Yuan took a deep breath, right now, everything was ready, and there was only one thing left...... That is the mixed metal to be added to pure copper, and only in this way can pure copper be turned into an alloy, and it can really be used as a weapon......

Lin Yuan vaguely remembered that when he was in school, the teacher said that bronze is actually an alloy of pure copper fused with a certain proportion of lead or tin.

Lead and tin ......

Lin Yuan looked up at the gradually darkening sky, and a smile appeared on the corner of his mouth.

It seems that these two things are actually not that difficult to find......
