The tortoise shell, its main use is mostly related to traditional medicine and cultural symbols.
In the field of traditional medicine, the ancients believed that this tortoise has unique medicinal effects. After specific processing, tortoise shell, tortoise meat and other parts are considered to be medicinal, used to deal with a variety of diseases. Such as tortoise shell, after processing, it may nourish yin and yang, kidney and bones, and it seems to have an improvement effect on some diseases of yin deficiency and yang, muscle and bone weakness. Its principle or because of the characteristics of the tortoise, the ancients used analogical thinking to believe that the toughness and longevity of the tortoise can endow the human body with corresponding benefits.
From the perspective of cultural symbols, the three-pointed tortoise also has special significance. In many ancient legends and myths, turtles are often regarded as auspicious objects, symbolizing longevity, tranquility and stability. In solemn ceremonies such as sacrifices, the three-pointed guijiao turtle may be sacrificed as a sacrifice. People hope to use its auspicious power to be blessed by the gods and keep the family and tribe safe and prosperous. And in some regional folk cultures, turtles are also associated with the concept of feng shui. Its existence or placement is believed to have an impact on the aura of the living environment and the rise and fall of the family's fortune.
However, with the changes of the times and the development of scientific cognition, some claims about the medicinal effects of the three-pointed guijiao turtle have not been fully verified by modern science. At the same time, in view of the need for ecological and environmental protection, many rare turtle species, including the three-pointed Gui Cape turtle, are strictly protected, and it is illegal to hunt, kill, eat, and trade wild animals and their products. People should re-examine such creatures from the perspective of science and protection to protect the ecological balance.

The synthesis method of 312-based mercury has been used in ancient times, and all methods have their own wonders.
First, it can be obtained by the interaction between mercury and specific halides under suitable reaction environments. In a closed vessel, the mercury and halides are mixed in a certain proportion, and then the heat is slowed down. During this period, it is necessary to carefully observe the signs of the reaction, adjust the temperature and duration in a timely manner, so that the reaction is smooth, and obtain pure 312-based mercury. This way, the temperature and proportion need to be carefully controlled, and if there is a slight difference, it will fall short.
Second, the reaction is initiated in the solvent with mercury salt as the starting material and a specific organic reagent. First dissolve the mercury salt in an appropriate amount of solvent, slowly add organic reagents, stir well, and make it fully react. In this process, the choice of solvent, the purity and dosage of organic reagents are all crucial. And under specific temperature and pH conditions, the reaction can proceed in the direction of generating 312-based mercury.
Third, with the help of some biosynthetic methods. In nature, some microorganisms have unique metabolic pathways that can synthesize mercury-containing compounds under specific conditions. By screening such microorganisms, creating an environment suitable for their growth and reproduction, simulating the natural ecology, guiding the metabolism of microorganisms, and making them produce 312-based mercury. However, this method requires a good understanding of the characteristics and growth environment of microorganisms to be effective.
All these synthesis methods have their own advantages and disadvantages. Although the chemical synthesis method is more direct, it requires strict reaction conditions; although the biosynthesis method is relatively mild, it requires profound biological knowledge and complex cultivation techniques. In practical operation, it is necessary to carefully choose the appropriate synthesis method according to specific needs and conditions to achieve twice the result with half the effort.

The three-pointed prism dog base is an ancient divine object, and its physical properties are very different.
Looking at its shape, the three-pointed prism dog base has the state of three edges, and the edges are sharp, as if it can break everything in the world. Its quality is stronger than fine steel, and it is damaged when touched by ordinary weapons. According to the book "Tiangong Kaiwu", a craftsman once hammered this stone with hundreds of refined steel, and the steel hammer was completely broken, but the stone dog base was unscathed, and its hardness is evident.
In terms of its weight, the three-pointed prism dog base sinks like a mountain. It is difficult for ordinary people to shake the slightest bit, even if they pull it with a few strong horses, they will not move at all. In the past, there were powerful people who wanted to test its weight, and they devoted all their strength to holding it, but it was like a mayfly shaking a tree, and it took no effort. From this, it can be seen that its density far exceeds that of ordinary things.
As for its color, the three-pointed prism dog base is dark in color, and the dim light is faint, as if it contains endless mysterious power. In the dark, although its light is weak, it can illuminate the surrounding land, like a candle in the dark night, mysterious and charming.
Furthermore, the three-pointed prism dog base is not afraid of water and fire. The flames are scorching, its color remains unchanged, and its body does not melt; soaked in floods, it does not rot or corrode. There were once aliens who used the true fire of samadhi to calcine this stone, and the fire was fierce. However, the stone dog was as stable as Mount Tai in the fire, and when the fire was extinguished, the stone was still the same as before, which shows its ability to resist fire and water.
This three-pointed prism dog base has very strange physical properties. It is a rare foreign object in the world, adding many mysterious colors to the world.

It is also a material for casting swords. During storage and transportation, everything is complicated and should not be careless.
When storing, the first environment is dry. Dry is not easy to rust. If it is in a humid place, its quality is easily damaged, and rust is gradually growing, and it will be unusable for a long time. It is necessary to choose a high dry place and support it with a wooden frame, several inches off the ground, so that it is well ventilated and moisture is difficult to invade.
Second and protective equipment. When wrapped in felt cloth to prevent it from colliding with each other, causing gaps and wear. And it should not be mixed with other things, especially acid and alkali to prevent its quality from being eroded.
During the transportation period, the road conditions should be checked first. If the road is rough and bumpy too much, it may hurt its edge. It needs to be lined with a thick cushion, and the luck should be slow and stable. The escorts should also be cautious, always pay attention, so as not to be damaged by accident.
Furthermore, the road of concealment is also required. Such sharp weapons should not be swayed across the market to prevent bad people from coveting and causing disasters. They should be carried with concealed weapons to avoid people's eyes and ears.
All these things are related to the integrity of the three-edged peg leopard base, and should not be ignored. Only with caution can we protect its quality and use it fully.

"Tiangong Kaiwu" says: "The three immortal pills are made by the combination of mercury, fire nitrate and alum." The preparation of the three immortal pills is quite complicated, related to the temperature and the delicate proportion. Its impact on the environment and human health needs to be carefully examined.
In terms of the environment, the process of preparing the three immortal pills involves chemical reactions of fire nitrate, alum and other substances, or the escape of harmful gases. For example, during refining, compounds such as sulfur and nitrogen may be emitted in the air, causing the air to be dirty, the surrounding grass and trees may wither, and the water source may be polluted, making it difficult for organisms to survive in the water, the ecological balance will be broken, and the environment will gradually deteriorate.
As for human health, the three immortal pills contain mercury, which is highly toxic. During the preparation, if the protection is not good, the inhalation of mercury-containing dust or gas will easily invade the human body. At first, there will be headache, dizziness, fatigue, and for a long time, it will damage the function of the liver and kidneys, causing tremors in the limbs, trance, and sores in the mouth and teeth. Even if the user accidentally overdoses or exposes for a long time, the mercury poison will accumulate in the body, damage the nervous system, digestive system, and even endanger life.
Therefore, although the Three Immortals Pill has been used in ancient medicine, alchemy, and other fields, its harm to the environment and human health should not be underestimated. When preparing and applying, when weighing the pros and cons, handle it with caution to ensure environmental peace and human health.
