Among the many things involved in "Tiangong Kaiwu", the main use of 2-Jiang-3 turtle (suspected of being "finless porpoise", ancient times for finless porpoises or similar expressions) is quite special. In ancient times, one of the important uses of finless porpoises was related to fisheries. Because finless porpoises are sensitive to changes in water flow and climate, fishermen often observe the movement of finless porpoises to measure water conditions and weather. For example, finless porpoises frequently jump out of the water, or indicate that wind and rain are approaching, undercurrents in the river are surging, etc. This is an important reference for fishermen to arrange fishing operations and ensure safety, and help them grasp the appropriate fishing time and area.
Furthermore, finless porpoises are also meaningful to sail on water. There are many risks in sailing on water, and the swimming state of finless porpoises can be used as a guide for When the finless porpoise swims around the boat, or has a steady forward state, the boatman or feel that the waterway is smooth and there is no great danger; if the finless porpoise behaves abnormally, such as swimming quickly and making special sounds, the boatman will be alert, pay attention to potential dangers such as underwater reefs and whirlpools, and adjust the route in time to ensure the safety of the boat.
In addition, from a cultural perspective, the finless porpoise is regarded as a symbol of the water gods in some areas. People are in awe of it, and there are sacrificial activities every time. Before working on the water, fishermen, boatmen, etc. may hold simple ceremonies to pray for the blessing of the finless porpoise, and may it protect the fishery and ship safely. This cultural tradition reflects the ancient people's respect for the power of nature, through respect for finless porpoises, seeking harmony with nature, and finding spiritual comfort and security in the unpredictable aquatic environment.

2-%E6%B0%9F-3-%E5%90%A1%E5%95%B6%E7%94%B2%E9%86%9B, this is a rare wonder in the world. It has many unique physical properties and is amazing.
The first thing to bear the brunt is its hardness. The body of this fish, as if it has been tempered by heaven, is as hard as gold and stone, and it is difficult for ordinary swords to hurt it. Looking at its body surface, although it is not as shining as metal, it feels that its texture is dense when touched. It seems to have a layer of invisible armor to protect it. Even if it is hit hard by external forces, it can be handled with equanimity, leaving only a slight trace, which shows that it is very tough.
Furthermore, its density is also different. Placed in water, it does not sink or float, and it can just float in a specific water layer, as if it has reached a wonderful balance with water. This characteristic may be due to the special structure of its body, which makes its specific gravity perfectly fit with the surrounding water body, like a god-given magic method, it comes and goes freely in the water, not subject to ups and downs.
And its thermal conductivity is also unique. When approached by a heat source, it is heated very slowly, and the heat conduction is uniform, so that it will not be damaged by overheating in one place. It seems that it has a delicate heat dissipation system that can effectively adjust the temperature. Even in a high temperature environment, it can maintain its own stability and not endanger life due to overheating.
In addition, the electrical conductivity of this fish is also quite strange. It is neither a good conductor nor an insulator, and it is in a delicate intermediate state. When the current passes, there seems to be a layer of hindrance, but it is not completely blocked. Its conduction and hindrance mechanism to the current is like a labyrinth of hidden mysteries, which is puzzling, but it attracts everyone to explore.
2-%E6%B0%9F-3-%E5%90%A1%E5%95%B6%E7%94%B2%E9%86%9B With its unique physical properties, it is unique in the world, like a masterpiece carefully carved by a craftsman, adding a strong color to the wonderful picture of all things.

2-%E6%B0%9F-3-%E5%90%A1%E5%95%B6%E7%94%B2%E9%86%9B, its chemical properties may be called stable. Looking at the nature of this substance, under normal circumstances, it can settle down without drastic change.
covers the wonders of its structure, and the bonds between atoms are tight and orderly. This tight structure is like a strong city barrier, which is difficult for foreign enemies to invade, and is not easy to be moved by ordinary conditions.
In various chemical reactions, if you want to change it, you must have a special situation. Common temperature, pressure, and ordinary reagents are difficult to shake their properties. Only with high energy input or special catalysis can there be a possibility of transformation.
For example, if it is burned by fire, ordinary substances or instant transformation, then 2-%E6%B0%9F-3-%E5%90%A1%E5%95%B6%E7%94%B2%E9%86%9B, if the temperature does not reach its specific domain, it will only feel slightly hot, and the main body will not be damaged, and its properties will remain.
And try it with various solutions. The common acid and alkali liquid is poured into it, and it is like a stone thrown into still water, which does not make waves, and no significant transformation is seen.
And it is in the air, after time, and it rarely combines with oxygen, water vapor, etc. It is because it can maintain its inherent state in all kinds of common environments, and its transformation can be said to be very stable. However, this does not mean that it is absolutely immutable, but the conditions for change are unique and harsh, and it cannot be easily caused.

If you want to make a two-way and three-way armor, there are three ways.
One is good materials. If you want to get the best, the first material is the first. You need to be in the realm of living water, in which the armor is alive and healthy, and the water is clear, and there is a risk of dyeing. This kind of armor is beautiful and rich, and it is above the well-made armor. If you get deep mountains and clear pools, or tributaries of rivers, the armor will be born in this place, and you will definitely be able to add color to it.
The second is fine cooking. When you have obtained the armor, the method of cooking is very important. First, use the water to wash your body and get rid of it. Use the rice over a slow fire, and add the taste products such as rice, ginger, garlic, etc., to remove the fishy and increase the fragrance. Then add wolfberry, rice and other materials, not to add its flavor, but to increase the effect of life. It is necessary to pay attention to the slow fire, and do not let the fire burn until the meat and bones of the nail are crispy, and the juice is thick, which is superior.
Third, keep the ancient method. Ancient cooking, there is a way to make armor. Or steam it with bamboo to keep the original taste of the nail; or use it in a crock pot to make the taste go deep into the texture. We study ancient books, follow the predecessors' instructions, take its essence and remove its dross. In the cooking process, integrate the ancient meaning, and we can make a good one with ancient food.
To make a two-way and three-way armor, you need to use good materials, fine cooking, and keep the ancient method. All three are combined to make a delicious food.

Those who want to preserve and transport mercury should pay attention to all things.
The first choice of materials is excellent. The quality of mercury is pure, and impurities do not exist, so that the effect of true mercury can be obtained. If the quality of mercury is impure, such as gold mixed in sand, if it is applied to the technique, it will produce a bad pool, which will affect the work and results.
The second time, the container is suitable. The storage of mercury needs to choose a stable and airtight device. Like the ancient furnace, the material is firm and tight, and it does not leak or leak, so that the mercury gas is restrained. If there is a gap in the container, the mercury gas will escape, like a fish falling out of the abyss, and it will fall short.
Furthermore, the environment is quiet. The place where it is stored should be quiet, avoiding the hustle and bustle The turbid energy does not invade, and the spiritual energy gathers. Just like a treasure hidden in a deep mountain, it is not disturbed by dust, and mercury can nourish its nature.
When operating the application, it is important to be precise in the rhythm. According to the ancient rules, observe the changes of yin and yang, follow the order of the four seasons, and do not move rashly. If you are walking on a boat on water and steer an oar at the right time, you can move along the river. If you violate the rhythm and misuse its machine, the nature of mercury will be chaotic, and the work will not be accomplished.
When you are operating the application, you will be dedicated to your heart. If you are not sincere, your will will will not be firm, and if you are not dedicated, your will will be easy to disperse. Transporting mercury with a devout heart and focus, such as holding a scale and measuring objects A little slack, like a broken bow, is difficult to make a big use of.
In the preservation and transportation of mercury, all matters need to be paid attention to, and only by not slack can you obtain the mystery of the true Dharma and achieve wonderful work.
