Red Dye Beetles Chemical Engineering
There was an ancient craftsman who specialized in the research and use of the red bug to transform the wonders of the red pill. The red bug is also a genus of insects, and its body is small, often hidden among plants and trees. Its color is red-brown, and it likes warm and moist land, mostly gathered under the branches and leaves.
The craftsman first searched for the red bug, and observed its habitat, and knew that it was addicted to a certain tree. Every season, he carried a tool and went, climbing in between, scraping lightly with a fine grate, and collecting the red bug in the urn. Returning to the workshop, he placed the bug in the kettle, and slowly boiled it on a small fire. Water vapor evaporated in the kettle, and the body of the bug gradually melted, and the color was as red as blood, overflowing in the kettle.
Next, drain the juice with a cloth, remove the dregs, and obtain the clear liquid. Add all kinds of medicine to it, including the essence of plants and trees, and the powder of gold and stone, according to the formula, and it must be investigated. The medicine is put into the liquid, stirred evenly, and its color gradually changes, becoming more and more bright.
Then put a pottery urn, seal its mouth, bury it in the soil, and nourish it with the air of the earth. After ten days, dig it out, and see that the liquid has become an ointment, red like Danxia, delicate and radiant. After condensation, this ointment is red pill, which can be used as a color for painting things, and can also be used as medicine to promote blood circulation and pass menstruation, and its effect is extraordinary.
The craftsman made pills, using the ingenuity of chemical engineering, studying the nature of red scale, and the wonders of poor medicines, so he became this wonder, which was passed down to later generations and was widely used.
