Ethyl Butyryl Acetate as the core of the matter
There is a craftsman somewhere who specializes in the synthesis of things. I have heard of his ambition, but the Ethyl Butyryl Acetate is the sect, and he is poor in reason and explores its system.

The craftsman is in the room, listing all the utensils, all carefully selected, in order to obtain the goodness of Ethyl Butyryl Acetate. Observe its handling, first take all kinds of materials, and measure them carefully. With the warmth of the fire, keep the degree, I can't use it, I can't use it. In the meantime, I concentrate on the calm and keep my eyes fixed, and observe the change of materials, as if I were watching the wonders of the sky.

It is also not a day's work. At the beginning, there were many mistakes, but the craftsman was not discouraged. Investigate the reason and change the law. Failed and tried again and again, my heart is as firm as a rock. Finally, I got something, I made Ethyl Butyryl Acetate, looking at its color, clear and moist; smell its qi, fragrant and elegant.

The craftsman is based on Ethyl Butyryl Acetate, and thinks about its use. Or it can enter incense to make the fragrance long; or it can be supplemented with medicine to increase the effect of medicine. So I explored its path widely, hoping to be helpful to the world. When the four sides heard its ability, they all came to ask for it. The craftsman does not hide it privately, but teaches it with all his pockets, hoping that this technique can be passed on to the public and benefit all directions.
