The white cloth bag was pierced by a magic general's fingers, and thousands of poisonous bees swarmed out, which turned out to be honeycomb!

As soon as the buzzing sound appeared, the most poisonous bee in the Three Realms descended.

It's a tiger bee!

The tiger bee is huge and ferocious, and it is generally called the earth bee, also known as the tiger bee.

This wasp is the largest and most venomous of the bees.

The body color of the tiger bee is bright and usually yellow and black, that is, it has tiger-like markings, two large jaws on its head are developed and powerful, and there is a stinger on the tip of the abdomen that is connected to the venom glands in the body.

Unlike ordinary bees, which feed on pollen, Steller's bees feed not on these tiny powdery particles, but on insects and plants, and even cannibalism in bad climates when food is scarce.

Bee venom is a toxic protein composed of many amino acids, which can cause people to be poisoned, such as redness, swelling, itching, stinging and other allergic phenomena, and in severe cases, cause patients to die of shock.

Insects stung by tiger bees will die in minutes, even large animals will die within a few quarters of an hour if they are not treated in time, and even trees and flowers will dry up locally if they have sucked up their sap.

Steller's bees belong to the social insect tribe, and their members include a female who lays eggs, the queen, and a large number of worker bees, most of which are females, and the male bees are only a few.

"Are you at the end of your rope, start playing smart, the immortals are really shameless. ”

Huang Tian was disdainful, and then he reminded the demon gods: "Be careful, there is Qin Yuan recorded in the "Book of Scriptures" in it. ”

Qin Yuan's body shape is very similar to that of bees, but it is as big as a mandarin duck, and all birds, beasts, humans and animals stung by it will be killed immediately, and even plants and trees will wither and die.

It is probably the largest bee known in the Three Realms, so the author classifies it as a type of bird. But its nature has not changed, and its needle and venom are its most powerful weapons.

The maximum body length of ordinary bees will not exceed three centimeters, and the average mandarin duck is thirty centimeters long, which is more than ten times the length of bees.

The weight is even more world-apart, the venom secreted by ordinary bees at a time is three or five milligrams, but if it is Qinyuan, the venom may be as high as dozens of grams at a time, and it is estimated that even elephants will be poisoned alive at such a dose.

Although the demon gods were a little afraid of this blind immortal's use of Tiger Bee and Qin Yuan, they had not yet reached the point of fear.

They did not panic because of this, but stood like stone clay sculptures, motionless, and even the breath of breath gradually disappeared.

"Hmph, Qin Yuan, Tiger Bee, this method is too unjust and bright!"

During the day, the Demon Emperor's voice rang out from all directions, and then he snorted coldly: "The fog is lost!"

After the sound of the day disappeared, gradually, the entire ice pick world began to haze, and it became more and more dense, and in a few breaths, he could not see his five fingers.

The fog is coming!

When the relative humidity reaches a certain state, the water vapor in the air will condense into fine water droplets suspended in the air, reducing the visibility at ground level, and this weather phenomenon is called fog. Fog is more abundant in spring from February to April.

The conditions for its formation: one is cooling, the other is humidification, increasing the water vapor content.

The types of fog are radiation fog, advection fog, mixed fog, evaporation fog, etc.

Fog is a weather phenomenon composed of tiny water droplets or ice crystals suspended in the air near the surface, which is the product of the condensation of water vapor in the air near the surface, and it is in a liquid state.

Saturation is reached when the water vapor contained by the air reaches its maximum capacity.

And the higher the temperature of the air, the more moisture can be contained in the air.

If the air contains more water vapor than the amount of saturated water vapor at a certain temperature, the excess water vapor will condense and when enough water molecules combine with the tiny dust particles in the air, and the water molecules themselves will bond to each other, becoming small water droplets or ice crystals.

The amount of water vapor in the air exceeds the saturation amount and condenses into water droplets, which is mainly caused by the drop in air temperature. This is also the reason why autumn and winter mornings are foggy.

If the ground heat is lost, the temperature drops, and the air is quite humid, then when it cools to a certain extent, a part of the water vapor in the air will condense and become many small water droplets, suspended in the air layer near the ground, and fog will be formed.

Both it and clouds are caused by a drop in temperature, and fog can actually also be said to be clouds close to the ground.

The temperature is relatively high during the day, and the air can hold more water vapor.

But at night, the temperature drops, and the ability of the air to hold water vapor decreases. As a result, some of the water vapor condenses into fog.

Especially in autumn and winter, due to the long nights and the chance of cloudless wind, the ground heat dissipation is more rapid than in summer, so that the ground temperature drops sharply, so that the water vapor in the air near the ground is easy to reach saturation in the second half of the night to the morning and condense into small water droplets, forming fog.

The morning temperature is at its lowest in autumn, winter and spring, when the fog is at its thickest.

The conditions for the formation of fog are cooling, humidification, and condensation nuclei, which increase the water vapor content.

A kind of fog is formed by radiative cooling, mostly appearing in the night and early morning when it is clear, breezy, and the water vapor near the ground is relatively abundant and relatively stable or there is a temperature inversion, which is called radiation fog in meteorology; the other is the fog formed by the horizontal movement of warm and humid air through the cold ground or water surface, and the water vapor in the air is gradually liquefied by cold, which is called advection fog in meteorology; sometimes the fog formed by both reasons is called mixed fog.

It can be seen that these conditions can be met in late autumn and early winter, especially in the morning of late autumn and early winter.

Smog in towns is caused by another cause, and that is people's activities.

Morning and evening is the time when a large amount of smoke and dust is emitted, when the pollutants are not easy to diffuse under the conditions of low pressure and low wind, and combined with the water vapor in the low-level air, it is easier to form smoke and dust, and this smoke and dust often lasts for a long time, resulting in long-term foggy days.

The reasons for the dissipation of the fog are, firstly, due to the warming of the underlying surface, the evaporation of the fog droplets, secondly, the increase of wind speed, which blows away or lifts the fog into clouds, and secondly, the turbulent mixing, the water vapor is uploaded, the heat is transferred, and the near-surface fog droplets evaporate.

The duration of fog is mainly related to the dry and wet local climate: generally speaking, arid areas are mostly short fog, mostly dissipating within half an hour, and humid areas are most common with long fog, which can last for about three hours.

When white light hits a transparent object, the light it transmits is mainly the same color as the transparent object, and the other colors are absorbed by the transparent object.

If a transparent object can transmit light of all colors, then the transparent object is colorless, such as ice.

However, when the water turns into fog, many reflective surfaces are formed. At this time, the light cannot be penetrated, but is reflected, that is, the light of various colors is reflected, so the fog becomes white.

There are many types of fog classifications, which can be divided into two categories: air mass fog and frontal fog according to the weather conditions of the fog:

Air mass fog has:

1. Radiation fog: The heat from the ground radiates into the sky after sunset, and the cooled ground condenses the nearby air. As a result, the moist air drops below the dew point and forms numerous small droplets of water suspended in the air, which are called radiation fog.

It mainly occurs in the early morning of autumn or winter, when the weather is clear and the wind is weak, and it dissipates naturally shortly after sunrise or when the wind speed increases. It mostly occurs at night and early in the morning when it is sunny, breezy, and the water vapor near the surface is relatively abundant and stable, or there is a temperature inversion.

2. Advection fog: The fog formed by the horizontal movement of warm and humid air through the cold ground or water surface and the gradual cooling is called advection fog in meteorology. This fog is often accompanied by drizzly weather.

3. Evaporation fog: that is, cold air flows through the warm water surface, if the air temperature is very different from the water temperature, the cold air near the water surface will condense into fog due to the evaporation of a large amount of water vapor from the water surface.

At this time, there is often an inversion layer on the fog layer, otherwise the convection will dissipate the fog. Therefore, the evaporation fog has a small range and weak intensity, and generally occurs around the pond in the second half of the year.

4. Uphill fog: This is the fog produced by moist air rising along the hillside and adiabatic cooling to supersaturate the air.

This moist air must be stable and the slope of the hill must be small, otherwise convection will form and fog will be difficult to form.

5. Advection radiation fog: Advection radiation fog is caused by the combined action of advection and radiation.

Frontal fog: Usually occurs near the front where cold and warm air meet, and is usually followed by continuous rainfall. There are both strikers and forwards, but most of them are near warm fronts.

The pre-front fog is formed by raindrops in the warm air clouds above the front falling into the cold air on the ground and condensing by evaporation, which causes the air to reach supersaturation, while the post-front fog is formed by the warm and moist air moving to the area occupied by the cold air before the warm front and reaching supersaturation after cooling.

Because the fog near the front often moves with the front, the military often uses this front fog to cover the troops and launch a surprise attack on the enemy.

Mixed fog: Sometimes the fog formed by both of the above two reasons is called mixed fog.

Smoke: Smoke is a mixture of solid and liquid aerosols composed of smoke and fog at the same time.

Valley Mist: This one usually occurs in the valley in winter.

When heavier cold air moves into the valley, the warm air also passes over the summit and the temperature inverses, resulting in valley fog that can last for several days.

Ice Mist: Ice fog is formed when water droplets in any type of fog are condensed into ice chips.

It usually occurs when the temperature is lower than the freezing point, so it is commonly found in extremely cold places. It can be divided into dispersed aerosols and coagulation aerosols. The tiny droplets formed by atomization of the liquid at room temperature due to splashing, jetting, etc., are dispersed in the atmosphere to form a dispersed aerosol.

The liquid is converted into vapor and dispersed into the atmosphere due to heating, and then condensed into tiny droplets to form a condensed aerosol after being cooled.

Now, during the day, the Demon Emperor used these principles to create a "fog lost tower" that permeated everything and hid everything, causing Qin Yuan and the tiger bee to suddenly lose their way and become a waste that could not capture the target.
