Then, in order to ensure that the flames in the furnace reach a sufficiently high temperature and burn at a uniform speed, she also needs to make a blower.
She peeled some suitable tree bark and used branches as a frame to make a fan-shaped rotating spindle blower. It could perform mechanical movement with just simple repeated rotation, saving physical strength and increasing the wind power of the stove. The faster it rotated, the bigger the fire became.
She also had to make a bamboo slat, drill a hole in the middle so that the flames could pass through, and perfect the inside of the stove.
Now that the whole body is in place, it's time to smelt the iron.
There was spare charcoal in the thatched hut, which saved her time of burning charcoal. She first made a ceramic cup, then removed the iron piece from the stick and put it into the cup.
Then place the cup in the oven and position it upright. Pour enough charcoal around it, light the fire, and then continue to bake it at a high temperature for the rest of the time.
During this process, she needed to continuously add charcoal blocks to maintain the high temperature. Finally, after the iron sheet melted into water, she used tongs to lift the cup and poured the molten iron into a mold that had been prepared earlier to cool and shape it.
After much hardship, she finally obtained a few thin iron wires that were barely usable.
After obtaining the lock-picking tools, she carefully bent them into the desired curve.
First, bend the end of the wire into a right angle. Then try inserting it into the keyhole. If there are several small cylindrical iron rods in the keyhole, try pushing them all up and then turning the wire. This might open the keyhole.
However, she couldn't open it; it seemed the first method didn't work.
So she tried a different approach.
She bent the end of the wire into a triangle, slowly inserted it into the keyhole, and gently turned it in one direction. She kept her ear close to the keyhole, watching for any movement, and continued to insert it while turning it. If it didn't open after being inserted all the way in, she would repeat the process several times... Click!
Upon hearing a crisp, tinkling sound, Zheng Quchi's breath hitched, and his eyes suddenly lit up like candle wicks, bursting forth with light.
It's open?!
Her heart was racing, and her palms were sweating. She pulled off the lock and then lifted the lid of the brocade box...
But they discovered that what was inside was not the usual black, round pill, but a beautiful, slightly translucent white thing, resembling a plum blossom cake.
If it weren't for the faint smell of Chinese medicinal herbs emanating from it, she would have really thought it was just a piece of white cake about the size of a thumb.
"Is this really a miracle drug?"
Zheng Quchi, who was not very knowledgeable, couldn't help but begin to have doubts.
