Solid weapons can kill the enemy in the battlefield to win; excellent armor can protect the lives of soldiers, protect the security of the country's territory, and safeguard the dignity and stability of the country. In short, this product has important uses in people's livelihood, Baigong, and countries, and is indeed indispensable.

In order to make this thing today, in the process of synthesis, several things should be done carefully.
The first one is the choice of materials. The material must be excellent, and impurities should not enter. As the "Tiangong Kaiwu" says: "Where a mirror is cast, the mold should be made of gray sand, and the copper should be made of tin." When casting a mirror, the mold should be made of gray sand, and the copper must be combined with tin to get a good tool. The weight of this material is also related to the quality of the thing. The material of synthesis must be reviewed for its purity, degree of its properties, and make it suitable for its use.
The second rule is the combination of agents. The proportion of materials cannot be determined arbitrarily. "Where gunpowder is pure yang, and nitrate is pure yin, this universe is illusory. The amount of sulfur and nitrate is divided into the main and guest. "The production of gunpowder, the proportion of sulfur and nitrate, is related to its nature. The same is true for the synthesis of other things. The amount of material should be calculated in detail, and it should be accurately prepared, otherwise the quality will be poor and it will be wasted.
Also, the control of temperature is also. When the temperature is high, the material is changeable, and when the temperature is low, it is difficult to combine." When making gold foil, after it has become a thin sheet, it is wrapped in black gold paper and beaten with all its strength. "The creation of gold foil is controlled by the temperature when beating, so that the gold can be extended into foil. The process of synthesis, the height of temperature, should be adjusted according to the nature of the thing, so that it is appropriate and orderly.
And, the degree of time is also. Combining is not achieved overnight, the length of time is related to the formation of things. "Where ink is made by burning smoke and condensing it. Where the smoke is loosened to make ink, it will be immersed in water for a long time, and the essence will be divided by floating and sinking." The system of ink, burning smoke and condensing, loosening smoke will be immersed in water for a long time, and the quality will be fine and coarse by dividing the length of time. Combining other things also requires time. When the time is appropriate, things are good, and when the time is over or not enough, it is not appropriate.
Furthermore, the method of doing it is also the method of doing it. If the law is correct, it will go well, and if the law is wrong, it will result in a loss. "Where a bell is cast, the higher one is made of copper, and the lower one is made of iron." The method of casting a When combining, the method of operation should follow the rules, and do not violate or mess.
The process of combining, material selection, agent preparation, temperature control, time, and practices must be paid attention to in order to obtain good things.

There are things today that are more unique than other assimilated products. This is an important matter to investigate.
Watching all things of the same kind, many follow the convention and rely on the old practice, although it has its own use, it is rare to be transcendent. And what I am talking about is just like the wonderful creation of heaven's work and creation, which is unique and different from everlasting.
Its quality is also delicate and solid, like fine gold and jade, which has not been damaged by the years, and has become stronger and stronger through the rain and rain. Unlike other things, it is brittle in the case of a slight cold, and soft in the case of a small heat.
Its shape is also ingenious, and it cannot be easily imitated by human strength. It may be winding like a dragon or a snake, or majestic like a mountain or sea, every twist and texture contains the essence of nature, which is by no means what the layman can do. And its shape is not only beautiful, but also complements its practicality. If you use it, you will be handy and get twice the result with half the effort.
Furthermore, its nature is also unique. In hot summer, it can generate cool, and in cold winter, it can repel cold. It is like a spiritual thing that knows people's feelings and is in line with the sky. Unlike other assimilated products, or biased, or at a loss, it is difficult to respond to the needs of all changes.
Its power is also extensive and outstanding. It can not only be a good tool for home, making life convenient and comfortable; it can also be a treasure of the state, helping all kinds of industries to prosper. The single function of non-other things can be compared, but it is actually a combination of many strengths, and has the ability to travel through the sky, latitude and earth.
The uniqueness of this thing is complete in quality, shape, sex and function, and it can be compared to non-other assimilated things. It is a treasure made in heaven and earth, and it should be cherished and used well, so that it can be exquisite and show its extraordinary value.
