Shan took a wooden stick, drilled a hole in it, fixed the wooden stick on the piston rod with isinglass, and said with a smile: "Try it, see if this works better."
Yao Xiaoqing tried it and found that it was much easier to use. The finished air blower looked somewhat similar to the air pumps of later generations.
Yao Xiaoqing thanked him for crossing the mountain, carrying a simple blower home and a dustpan, and went to the pond.
I saw that the firewood pile was out and the ore fell into the ash heap.
Use bamboo clamps to pick up the burned ore, place it on a thick stone slab, use a stone hammer to smash it, put it into a dustpan and place it next to the kiln.
Pick up the blower and align the blower with the air inlet of the kiln. After the connection is complete, fix the blower in the pit and use a circle of clay to reinforce it.
Grab some clay and paste it thickly at the connection between the punching bag and the air inlet to prevent air leakage.
I picked up some branches and pine needles and put them into the kiln to light. I put the charcoal into the kiln. After the charcoal burned, I poured half a frame into it.
Pour the ore in the dustpan on top of the charcoal, then pour half a frame of charcoal on top to cover the ore.
Yao Xiaoqing patted the dust on his hands, went over to lift the wooden rod of the piston, and pushed and pushed the air. With the sound of "huchi" and "huchi", the charcoal ignited.
After a while, red flames came out of the stove.
While pumping and blowing, she added charcoal to the stove. The red flame in the stove slowly turned into a golden orange color, and she was so tired that she was sweating profusely.
When Hua came to find her, Yao Xiaoqing was already panting from exhaustion and waved to her: "Come and help."
"Hey!" Hua agreed with a smile and went over to take over the task of pumping and compressing the blower.
She stretched her neck and glanced at the fire in the furnace. She didn't see anything being burned, so she asked strangely: "Xiaoqing, what are you doing?"
Yao Xiaoqing smiled and said: "I'm trying to refine something, but I haven't succeeded yet."
The two took turns pulling the blower, and they waited until the sun went down to finish burning the two baskets of charcoal before stopping. The ore in the furnace had stuck together and turned into a pile of red stone balls.
Yao Xiaoqing clamped it with two wooden sticks, and the wooden sticks were instantly ignited. After trying to clamp it for a few times, he took it out of the stove and placed it on the thick stone slab.
Let Hua hit the stone ball with a stone hammer, and sparks will fly when the hammer hits it.
The residue wrapping the stone ball was forged and fell off, revealing the red stone ball inside.
When the residue falls to the ground and cools, it turns into black-gray gravel.
Yao Xiaoqing poured the water from the wooden ladle onto the red stone ball. With a "chi" sound, the stone ball turned into a black iron block.
After carrying most of the iron ore in the basket, she was able to refine a piece of iron as big as a small bowl. She didn't know whether the iron ore was rich iron ore or poor iron ore.
Hua looked at the iron ball and said, "Xiaoqing, what's the use of this black thing?"
Yao Xiaoqing looked at her and smiled and said: "It will be of great use. You go back to the canteen to help. I will go back later."
Hua looked at the sky and said, "Okay, the sun has gone down, and it's time for the leader and others to come back."
Yao Xiaoqing had just tidied up the bamboo shed when she heard a "bang bang" bang on the door. She hurriedly ran over and took off the door bolt. She saw Shan Amu and Chun Amu standing with the collecting woman.
Outside.
"Why do you look unhappy?"
"Alas!" Shan Ammu sighed, "We met a group of shameless women who followed us and robbed the food we found."
Yao Xiaoqing raised his eyebrows and said, "Oh! Is there a new tribe coming again?"
Shan'am curled his lips and said, "I don't know where they migrated from. They are taller than us, and we can't understand what they are saying. Whoa, whoa, whoa, they all smell bad."
Yao Xiaoqing glanced at the disheveled hair of several women and said, "Looking at you, did you fight with them?"
Shan'am nodded, "Yeah! We had a fight with them."
Yao Xiaoqing looked at them, "Did you win?"
The woman named A Hong nodded proudly, "We won, we rode on them and beat them badly."
Yao Xiaoqing smiled and said: "Okay, it's good if you win." A group of people walked back laughing.
Yao Xiaoqing took the iron piece back and put it away, and saw Mu Feng and Zhi coming back carrying rock salt.
"Xiao Qing, is father back?" Mu Feng asked.
"No!" Yao Xiaoqing hurriedly stepped forward and opened the warehouse where the rock salt was stored, "Put it in quickly!"
Zhi put down his backpack and came out and sat down under the eaves of the corridor, fanning himself with his hands, "Ouch! It's so hot today!"
Yao Xiaoqing took out the water jug and poured him a bowl, "Brother She, drink water!" The water in the jug was soaked with bamboo cores, which has the effects of relieving heat, quenching thirst, clearing away heat and detoxifying.
Zhi took a sip and drank it, wiped his mouth, looked at her with a smile and said: "You said you can't drink raw water. We didn't dare to take a sip of water in the mountains. After drinking the water in the bamboo tube, we would have died of thirst.
.”
The male bull put the rock salt and came out, smiled and knocked it: "You kid, Xiaoqing is doing it for our own good, you want to get pregnant!"
"You just want to have a big belly." Zhi patted his leg.
Spear and a few warriors came out and held the bull in their arms, "Mu Feng come out quickly, let's go to the river to take a bath and cool down."
"Okay." Mu Feng came out of the warehouse, and a dozen men walked outside, arm in arm.
Yaohu and the others also returned to the tribe. A dozen people captured several hares, a dozen pheasants, turtle doves, several goats, and a wild boar. Everyone sighed, saying that compared with the last summer, the prey was too small.
Less and less.
Yao Xiaoqing said to Yao Hu: "Father, Shan Amu said that they met some women who couldn't understand what they were talking about, robbed them of the food they collected, and even had a fight with them."
Yao Hu didn't know where these people were from, so he frowned and said, "We can all understand what people in this area speak. Could it be that they migrated from far away?"
Yao Xiaoqing thought of something, "Father, I couldn't understand the words of the men that Yuzi and I met in the bamboo forest. Could they be from the same place?" She guessed that it was caused by the cold winter and lived in the cold.
Local people have no living space and migrate to warmer places during the summer.
Muba looked at Yaohu and said, "Chief, it seems that someone has migrated from a very far away place. Those women who dare to snatch food don't seem to be kind people."
Yao Hu nodded, "Everyone, please carry the prey to the canteen first, then go back and wash yourself, and eat the food before we talk."
Everyone agreed, carried the prey and left.
After they all left, Yao Xiaoqing went into the house and took out the iron, smiled proudly, and handed it to Yao Hu, "Father, look!"
Yao Hu took it, it was cool and heavy in his hand, "What is this black thing?"
Yao Xiaoqing looked at him with a smile, "Father, this is iron, it can be of great use."
