"In fact, Changbai Mountain was originally a dormant volcano that has erupted several times in history, so it has formed a unique landform here, so that people here can feel the magical beauty, majestic magnificence, primitive nature and infinite scenery brought by nature!

As the saying goes, 'all those who come are yearning, and those who have come are all staying'!"

In fact, Changbai Mountain is not only beautiful and charming, but also very rich in resources, the species of animals and plants are called a variety of species, which can be said to be the most representative typical natural complex in the northern half of Eurasia, and it is also a rare 'species gene bank' and 'natural museum' in the world.

Anyway, I've been wanting to come here ever since I learned about it, and this time I finally got what I wanted. ”

This has always made Zhang Yang yearn for it, and now that he has finally set foot on this land, he is also very excited, and he thinks that he will stay here for seven days in the future, and he has long been unable to hold back the desire to move.

I saw him bathed in the warm sunshine of the morning, facing the coolness brought by the autumn wind, and stepped into the mysterious and primeval forest full of nature in front of him.

All the way forward, without any words, the drone is also quietly suspended in mid-air, flexibly avoiding those tall trees that have long existed or newly planted, in fact, whether it is in it, or through the fans who appreciate the picture, at this time are quietly feeling this forest with natural history, and experiencing the historical heritage.

The weather in the morning is still a little cooler, especially after going deeper into the forest, the tall trees gradually obscured the wanton warm sunlight in the sky, and the perspective of the outside world appeared in front of everyone's eyes, after all, the light in the forest area is still not as good as outside the forest area, it looks a little dim, it is estimated that the deeper you go, the closer you get to the forest that existed in this land earlier, the more dim the light will be, just like at this time Zhang Yang has felt the slightest dampness in the forest area.

There were no roads in the forest, and there were many people walking, so the paths that were stepped on with obvious traces were formed, which were obviously opened up for future generations by those who often lingered in this primitive man.

On the ground are the fallen leaves scattered in autumn, but it is believed that under these new-looking fallen leaves must be the thick humus layer that has accumulated for many years, why people often say that the forest is not easy to extinguish as long as it is on fire, the root cause is the thick humus layer on the ground.

Once these things in the ground are ignited, the continuous forests will be quickly covered by fire, and the humus layer on the ground will form underground dark fires, which will cause great difficulties in fighting forest fires, which is also the reason for the existence of the warning line that fire is not allowed in forest areas.

Zhang Yang, who was walking in it, looked up and looked around, and from time to time there was the crisp and pleasant sound of birds and the chatter of some unknown animals.

"Do you know that there are five prohibitions in entering the forest?"

In fact, most people can often hear the similar slogan that everyone is responsible for forest fire prevention, many people only know that they must not use fire at will when entering the forest to prevent fires, but they do not know the specific details, for some people, the fire, is not the same as in the city, where there is a fire to extinguish where, some people do not understand why forest fires are more serious than urban fires.

Just as some people were asking in doubt, Zhang Yang suddenly squatted down after finishing speaking, and stretched out his hand to pick up the thick humus layer underground.

"You look here, many people think of urban fires instantly associated with the loss of property and life, people who have this idea are for the purpose of a small family, but forest fire prevention is everyone's problem, you must know that according to the statistics of the Food and Agriculture Organization of the United Nations, now 12 million hectares of forests disappear every year in the world, that is, an average of 20 hectares of forests are wiped out every minute.

As for why I just said that forest fire prevention is everyone's business, to say the most simple truth, without forests, the oxygen on the earth will gradually decrease, and you can imagine what the consequences are.

That's why countries are now paying great attention to environmental protection. ”

Since his current live broadcast has taken a little research purpose, and as a member of the big family of the earth, although some words are a bit boring, he still feels the need to say it.

The corrosive layer in the ground is actually muddy leaves and some miscellaneous flammable materials, which looks very disgusting, let alone touching, at this time, Zhang Yang grabbed a lump of black-brown rotten leaves in his hand and lifted it in front of the drone.

"Look at these humus layers, why I say that forest fires are more difficult to extinguish than urban fires, most of the reasons are because of these things, in fact, the fire on the surface and the fire on the forest are relatively easy to extinguish, but if this thick humus layer is ignited, it will form an extremely dangerous underground fire, this fire is hidden, the temperature is extremely high, the harm is great, it is not easy to find, which is why after each forest fire is extinguished, a part of the fire rescue and guard the fire site must be left, and an isolation zone must be established to prevent the possible resurgence of ashes and these underground fires。 ”

Zhang Yang casually threw the rotten leaves in his hand to the ground, then picked up some newly fallen leaves on the ground and wiped the dirt on his hands, then got up and continued to walk forward.

People say that the forest is mysterious, because there are places that few people have set foot in, which can make people have an unknown caution, and at the same time there are many elves hidden in life, which are not only those wild animals that are alive and jumping, but also those precious trees with a long history, which are not the precious resources left by nature to human beings.

"Actually, as most people say, the fresh air in the forest is a very good place to regulate the body and mind, but that is only relative to the periphery, but if you look at the inside of the forest now, anyway, what I smell is not only the fresh air rich in life, but also a rotten smell. ”

The smell of decay he refers to is naturally the rotting leaves and food residues left by various animal hunting, and even some gases accumulated from the lack of sufficient light for many years, such as miasma, of course, there is no miasma here, after all, the formation of miasma requires specific conditions.

Continuing to move forward, just as the people in the live broadcast room, including Zhang Yang, were still looking at the unique scenery in the forest, the drone hovering in the air suddenly changed direction......

Zhang Yang was also stunned for a moment, he knew that the drone assigned by the system would sometimes automatically shoot some of the pictures he ignored, so he also followed the drone that suddenly fell from the sky curiously, and came to the back of a big tree surrounded by a person, and indeed suddenly saw a skeleton, and this scene also immediately appeared in the picture of the live broadcast room, and even scared some timid people.
