1 Iodonaphthalenen

The viper's poison is very strong, and it causes great harm to people. Its main users are mostly at both ends of defending the enemy and hunting for food.
According to Guanfu's "Tiangong Kaiwu", everything between heaven and earth has its own nature. The poison of the viper is a sharp weapon for its defense against the enemy. In the world, the weak eat the strong, the body of the viper is not huge, and its strength is not strong. If there is no such poison, it is afraid of being devoured by other things. When encountering the enemy, the viper can inject poison into the enemy's body with its venom teeth, causing the enemy to be instantly paralyzed or even killed, so as to save the body and continue the life, which is also used to defend the enemy.
As for hunting, the viper often lurks on the side of the grass and cave, waiting for the prey to approach, quietly moving. Its mouth contains poisonous fangs, which instantly bite the prey, and the venom quickly invades the prey's body, making the prey unable to struggle, and the medicine will attack and die. The cobra can then be eaten to fill the stomach and discourage, so as to maintain the need for life.
And although the poison of the cobra is a serious problem for people, it can also be explored by doctors. The ancient healers tried to study all kinds of poisons, hoping to use the method of poison to fight poison and heal the sinking disease. If the poison of the cobra is used to obtain the method, it may be helpful in the treatment of difficult diseases, but it requires extremely high medical skills and experience, which is not easy to do.
The main users of the cobra are to protect themselves from the enemy, to hunt for food to maintain their lives, and to treat them with caution if they are poisonous to medicine or have potential benefits.

Saltpeter, its physical properties are quite unique. The color is white and often crystalline, mostly in the shape of particles or powder. Its texture is more brittle, and it feels cool to the touch.
Looking at its solubility, saltpeter is very soluble in water, and when dissolved, the temperature of the water drops sharply, as if absorbing the warmth around it. Its taste is slightly salty and bitter, and it tastes cold.
In terms of its chemical properties, saltpeter is oxidizing, and when it encounters flammable things, it can help it burn, and the fire is more intense. In ancient times, this property was often used in the production of firearms.
In nature, saltpeter is mostly born in hot and dry places and often exists in rocks and soils. The ancient people have observed and practiced for a long time before they can collect and refine.
Saltpeter has a wide range of uses. In the art of alchemy, it is an important raw material. Warlocks want to use its characteristics to refine the medicine of longevity. Although they have not achieved their wishes, they have contributed to the road of chemical exploration. In the military field, saltpeter is the key ingredient of gunpowder. The power of gunpowder, saltpeter is the most powerful, changing the pattern of war. In terms of people's livelihood, it is also used to pickle food, which can ensure that the food is not bad for a long time and has a unique flavor.

Arsenic, the chemical name of arsenic trioxide, is toxic. However, its chemical properties are relatively stable under specific circumstances.
Arsenic is normally a white frost-like powder. In the air, if there is no special condition to trigger, its chemical structure is relatively stable, and it is not easy to undergo violent chemical changes on its own. In a dry and normal temperature environment, it can maintain its inherent form and chemical composition for a long time.
However, if special chemical reagents or environmental factors change, its stability is easily broken. In case of reducing substances, the valence of arsenic in arsenic can change, which can lead to chemical reactions. In another example, in a strongly acidic environment, it may react with acids to form new compounds, showing the active side of chemical properties.
In water, although arsenic has limited solubility, the dissolved part will undergo reactions such as hydrolysis, which also indicates that its stability is not absolute. When the temperature rises to a certain extent, arsenic will sublimate, and in this process, if other substances participate, chemical reactions may also occur, changing its chemical structure and destroying its stability.
Therefore, the chemical properties of arsenic have a certain stability in general common environments, but under the influence of special chemical conditions, temperature, pH and other factors, its stability is difficult to maintain, and it will exhibit active chemical changes.

The sweet food of ancient times is also the method of making it, and it has been around for a long time.
"Zhou Li · Tianguan Tsukzai No. 1" has a saying: "The slurry man, the palm of the king has six drinks: water, pulp, Li, cool, medicine, and elixir, which are entered into the wine house. The gift of the guests is a little bit, and the wife gives the gift of drinking to the guests, and the gift of clear, medical, and bad is served." Zheng Xuan's note: "For medical treatment, the soup is fertile millet, and the brewing is the elixir." The elixir is the gift of the present.
The method of making it is to first take millet, glutinous rice and other grains, clean it, and stain it in water. It should be moderate in time. If it is long, it will rot, and if it is Then, after cooking, it is cooked and rotten like a meal. Take another malt, crush it, throw it into the meal, and mix well. The malt, the valley of germination, contains saccharification enzymes, which can make the starch in the meal turn into sugar.
Set this mixture in a warm place and wait for it to change. After a while, the meal gradually becomes saccharified, like the sweetness of honey. Then filter it with a cloth, remove the dross, and leave the clear liquid. Then put the clear liquid into the kettle, and slowly boil it over low heat. When boiling, you need to stir it frequently to prevent it from burning. When it is thick, depending on the heat and consistency, stop the fire at the right time. When it is cold, the rice is ready.
There are also those who use glutinous rice and barley as ingredients. Barley sprouts and crumbles into powder. The glutinous rice is cooked, mixed with the end of the malt, placed in a basin, covered with cotton wool, and catalyzed by warmth. Over time, it is saccharified and boiled through the juice.
The ancient taste, or for sacrificial offerings, or for daily food, has a sweet taste, nourishing power, and occupies a place in the diet.

Hidden things and transportation are related to the smooth flow of all things, and there are many matters in between, which must not be ignored.
When you are in the collection, you must first choose a house. A place with a high and open terrain must be selected to prevent the rain from soaking in it and causing it to rot. And the structure of the house should be solid and firm, able to withstand wind and rain, and can also prevent the damage of rats and insects. The shelves of hidden objects should be divided into categories, so that the organization is clear and easy to investigate. It is also necessary to inspect regularly, observe the degree of temperature and humidity, and take care of it in a timely manner, so as not to let the objects be damaged by air changes.
Furthermore, the hidden objects should also be carefully screened. It is good to inspect and calibrate, to remove those who are rotten and unusable, and not to mix them with good things, so as to damage other things. At the same time, when entering the forest, it is necessary to record its name, source, and date of entry in detail for later investigation.
As for the way of transportation, the first thing to do is to choose good men and animals, or people who are good at handling boats. If it is transported by land, the system of vehicles should be suitable for the things carried, and it should be sturdy and stable, and it should not be damaged in the way. If it is a waterway, the repair of the boat should be complete, and there should be no danger in the slightest. When sailing, measure the water and wind conditions, and follow the times to avoid its dangerous places.
When transporting, the parcels of the goods must be bundled tightly to prevent them from falling off and being lost. And the transportation journey should be scheduled for a certain time and not delayed. On the way, it should also be strictly guarded to prevent the risk of robbery. When handing over, both parties should check the name of the object carefully to ensure that it is correct before delivery.
In this way, when it comes to hiding and transporting everything, pay attention to everything, so that the goods can be intact and everything goes smoothly.
