The synthesis of a certain substance involves many delicate principles. Let me give you a detailed explanation.
In the past, there were wise men who studied this path, observing the creation of heaven and earth, and understanding the changes of yin and yang. At the beginning, it is necessary to carefully examine the nature of raw materials, and choose those that are pure to use. If you want to make a good tool, choose good materials first. This is the foundation.
As for the steps of synthesis, the first priority is the adjustment of the environment. Moderate temperature and moderation, and proper dryness and dampness are the most favorable conditions. It is like a nursery, and if it is not suitable for temperature and good soil, it will not be lush.
Then, apply ingenious techniques. Or make the raw materials mix together, calcined with fire, quenched with water, or catalyzed by medicinal power, or change the method according to the time. During this time, you need to be careful and precise. The intensity of fire, the amount of water, and the dose of medicine are all fixed, and the difference is a thousand miles.
Furthermore, if you want to do something good, you must first sharpen your tools. The utensils used must also be of high quality. Clean, unstained, sturdy and durable, so that you can help synthesize the work. Like a furnace for casting swords, you must be fire-resistant and durable, so that you can melt the gold and cast the blade.
And when synthesizing, you also need to focus on nothing else and focus on your attention. If you are impatient, it is easy to make mistakes. The ancients said: "With your heart," Concentrate on every step of the synthesis and examine its changes in order to achieve a good product.
And look at the holy method, there is inheritance and innovation. Inheritors, the experience and wisdom of predecessors, cannot be ignored; innovators, according to the needs of the time, open up new paths. The two complement each other, and the synthesis method is improving day by day.
In general, the synthesis of this substance requires excellent raw materials, suitable environment, ingenious steps, sophisticated equipment, attentive attention, and inheritance and innovation in parallel, so that its exquisite synthesis method can be obtained.
