There is a strange agent
in the world, called Formaldehyde Cyclododecyl Ethyl Acetal. Its formula is secret and hard to find, and those who obtain it are as precious as a arch.

In the past, there were hermits who lived in the mountains and were good at studying the art of medicinal stones. One day, I picked herbs from the precipice, and met a deer with colorful fur and herbs in his mouth, leading the hermit to a secluded cave. There is a stone box in the cave, which has been dusty for a long time. The hermit opens the box and obtains one side, which is the formula of Formalaldehyde Cyclododecyl Ethyl Acetal.

It is processed according to the recipe. The medicine is made, and its color is clear and the qi is quiet. The hermit uses it to help the world, and all kinds of diseases, or skin sores, or internal organs are not in harmony, and using it has a miraculous effect. Those who seek medicine from all over the world are close to it, and the hermit keeps applying medicine, and the reputation is far-reaching.

However, this agent is difficult to process, and the materials required are either born in a cliff or long in the deep sea, and it is not easy to collect. And the heat and time are fixed, and if it is slightly worse, the effect will be greatly reduced. Therefore, although we know its divine effect, those who can make it are rare. Healers in later generations all take it as their lifelong wish to obtain this formula, but in the vast world, this secret is still difficult to spread widely.
