Lead and mercury are the masters of hardware, the deity of eight stones, and the essential medicine for alchemy. It is covered in "Tiangong Kaiwu", although it is not as detailed as the book of special alchemy, there are still considerable aspects.
Lead and mercury are used in alchemy, and their functions are extraordinary. Lead is heavy in nature and heavy in quality, and its color is black. It belongs to water in the five elements. It can contain mercury, so that it does not fly or leave, and the two can be combined to form an pill. Mercury is fluid in nature, white in color, and belongs to gold in the five elements. It is unpredictable, and when it encounters lead, it coagulates, and the two are in a system, just like a couple.
The ancient alchemists regarded lead and mercury as a treasure. Based on lead and mercury, with other medicines, it is calcined by water and fire, and after nine revolutions, it is expected to obtain the elixir of longevity. Lead and mercury are used in alchemy, one is a cauldron, and the other is a medicine, both of which are indispensable. The tripod is made of lead, which is stable and sturdy, can hold medicines, and prohibits them from leaking. Mercury is the essence of medicinal pills, and it is made of lead, refined by water and fire, to remove its toxicity, and store its essence to obtain an elixir.
However, the poison of lead and mercury cannot be ignored. During the alchemy process, if you don't get the law, the poison of lead and mercury will overflow, which will hurt people even more. Therefore, alchemists need profound techniques and rigorous methods to ensure safety and obtain true pills. Although lead and mercury are important medicines for alchemy, if used properly, it can lead to longevity; if used improperly, it is a deadly poison. We must be cautious, use scientific methods, be reasonable, use its length, and avoid its harm, so as to live up to the wisdom of the ancients in alchemy.

A
A < b > A < b > is small in size and small in size, which is its characteristic on the physical scale. Its shape and amount are very small, so the gravitational shadow is small, and it can be easily moved in the air, stopped in various places, or attached to the surface of small things, such as the tip and stamen. It can stand on its feet, seemingly not affected by gravity.
Furthermore, when a < b > is moving, its wings can be fanned, and a force in the opposite direction of gravity can be generated to hold it floating and moving in the air. This principle of the force of motion is like a boat on a pan-wave, and the direction and speed are controlled by the force of motion. The shape of the wings and the rate of the material and the fan are all very important. The wings of the A


The legs of the A










The legs are exquisite and have a large adsorption capacity. This adsorption force is derived from the special micro-strength of the legs, which can form molecular forces on the surface of the object, such as van der force. With this ability, A can walk freely on vertical walls and smooth glass surfaces, as if walking on flat ground. This adsorption ability also allows it to quickly determine its body shape when it is at rest, so that it will not slip due to the dryness of the outside world.
And the reaction of the armor is agile, sensitive to the perception of physical stimuli from the outside world. Its eyes can sense the weakness, direction and color of light, so that it can quickly perceive the transformation of the environment, so as to avoid the sky or find food. At the same time, the sensory organs such as hair distributed around its body can sense the flow of space, vibration and other micro-physical signals, so that it can still make the right reaction in the instantaneous environment, survive and multiply.

Methyl ether, its chemical properties are unique. Methyl ether is flammable, and it is very easy to burn and explode under open flames and hot topics. Its vapor and air can form an explosive mixture, which will explode in case of fire source, and can spread to a considerable distance at a low place. In case of open fire, it will lead to backfire.
Methyl ether also has certain solubility. It is slightly soluble in water and can be miscible with most organic solvents, such as ethanol and ether. It is often used as a solvent in organic synthesis and other fields. The co-solute is evenly dispersed to make the reaction proceed smoothly.
The chemical properties of methyl ether are active. There are lone pair electrons on its oxygen atom, which can be used as nucleophiles to participate in many reactions. For example, the nucleophilic substitution reaction with halogenated hydrocarbons generates corresponding ether derivatives. This reaction is an important method for building carbon-oxygen bonds in organic synthesis.
Furthermore, methyl ether can undergo cracking reaction under acidic conditions. Under the catalysis of a specific strong acid, the carbon-oxygen bond of methyl ether is broken to form corresponding alcohols and halogenated hydrocarbons or other products. This reaction can be used to prepare specific organic compounds.
And because the molecular structure of methyl ether is relatively stable, it has a certain thermal stability. However, under the action of high temperature and specific catalysts, some rearrangement or decomposition reactions can also occur, resulting in different products, providing various paths for organic synthesis.

"Tiangong Kaiwu" records that the following method can be used to prepare lead pill (trilead tetroxide, $Pb_3O_4 $):
First make a thin sheet of lead, place it in an earth altar, heat it under the altar, and melt the lead. After the lead is melted, air is injected into the altar to oxidize the lead to form a myrtle monk ($PbO $). The chemical reaction equation is: $2Pb + O_2\ Delta }{=\!=\!=} 2Pb O $.
Then, take out the myrtle monk and study it with saltpeter ($KNO_3 $). Saltpeter is used here as an oxidant to help the myrtle monk further oxidize. The mixture is calcined in a fire, and under the action of saltpeter, it is converted into lead Dan. The reaction may be: $6PbO + O_2\ stackrel {KNO_3,\ Delta }{=\!=\!=} 2Pb_3O_4 $, saltpeter is thermally decomposed to provide oxygen, and the reaction formula is: $2KNO_3\ stackrel {\ Delta }{=\!=\!=} 2KNO_2 + O_2 ↑ $.
Another ancient method is to react with lead and vinegar to form lead acetate. Lead acetate is oxidized by air, and lead Dan can also be obtained. React lead and vinegar first: $Pb + 2CH_3COOH = (CH_3COO) _2Pb + H_2 ↑ $. The generated lead acetate interacts with oxygen and water in the air, gradually converts into basic lead acetate, and finally converts into lead Dan. This process is relatively complicated and involves a multi-step reaction, and components such as carbon dioxide in the air may also be involved. The reaction environment and specific reaction formula are affected by many factors, making it difficult to accurately summarize the complete process with a simple equation, but the general idea is this.

When storing and transporting the armor, many matters must be paid attention to.
First, the storage place must be dry and ventilated. Because the armor is mostly made of metal, leather and other things, if it is wet, the metal will rust easily, and the leather will perish easily, causing the armor to be damaged and lose its protective ability. If it is placed in a dark and damp cellar, in a few months, the iron armor will be rusted and the leather armor will be moldy and unusable.
Second, when storing, the armor should be properly placed. Do not stack and squeeze to avoid deformation. The various parts should be arranged in categories, such as helmets, armor, arm guards, leg guards, etc., in their respective positions for easy access and inspection. And a stable rack cabinet should be set up so that the armor can be hung on it in an orderly manner, so as not to be disorderly.
As for transportation, protection is especially important. Armor is not only a sharp weapon, but also its weight is not light. When handling, beware of collisions. It is necessary to pad with soft things, such as felt cloth, hay, etc., and wrap it tightly so that it will not collide with each other and be damaged during the bumpy journey. If it is transported by car, the bottom of the car should also be paved with thick objects to slow down the vibration.
Furthermore, the person handling it should know how to do it. The structure of the armor is complex, and some parts are fragile. If it is not used properly, it is easy to break. When everyone works together to carry it, they need to coordinate and obey the command, and must not act recklessly.
And during the transportation journey, you should keep an eye on the weather changes at any time. In case of rain, quickly cover the armor, and do not let the armor get wet in the rain. If exposed to the hot sun, the metal parts will be heated and expanded, or their performance will be affected, so it is necessary to choose a cool time for transportation, or build a shade on the car.
All these are things that should be paid attention to during the storage and transportation of the armor. If you are not careful, the armor will be damaged, which is related to the success or failure of the war.
