Miasma is something that modern people are not familiar with.

But in ancient times, this thing could kill people, making people talk about it with disgrace.

And this miasma is unique to the hot and humid areas in the south.

From the well-known deeds of ancient celebrities, I heard that so and so was exiled to the south, or further to Yunnan and Lingnan, and many of them were infected with the disease.

Those who were lucky enough to escape were severely injured.

Those who are unlucky will die on the way.

Why was there so much miasma in the ancient South?

It is said that the ancient economic and political center was in the north, while the south, especially Lingnan, was undeveloped. In addition, primitive jungles were everywhere, airtight, humid and hot, and the harmful gases caused by the death and decay of animals and plants could not escape.

This harmful gas is constantly brewing in the hot and humid environment, shrouding the primitive jungle and forming a miasma.

"Well, there is such a saying, but it's not entirely correct."

After listening to what Chen Ling said, Han Ninggui nodded slightly: "In addition to the putrefactive gases after dead animals and plants, some special minerals can also emit miasma, such as volcanoes containing sulfur. There are also special terrains that can also form miasma, such as

Some valleys on the Qinghai-Tibet Plateau... In short, there are many reasons, and they are not exclusive to the south."

"Ah? So there is quite a lot of miasma now?" Chen Lingqi asked.

"It's not much. How can there be more? Wherever there is miasma in the country now, just say it has been discovered. You can count them with one hand, so the presence of miasma here in your area is of value for research."

Han Ninggui said.

Later, seeing that Chen Ling and his fellow villagers were very curious about this thing, they explained it in detail.

As for why it’s gone now?

With the gradual development of various parts of the south, and the progress of large-scale projects such as mountain logging and logging, it will naturally disappear.

…

After lunch and a short rest, Chen Ling and others could not suppress their curiosity and insisted that Han Ninggui take them to see what miasma is.

They first went against the direction of the wetland, climbed a hill to the north, and passed through a forest full of wild chestnuts. Many of the wild chestnut trees here were more than two hundred years old.

people.

The southern slope is a sunny slope, where wild fruit trees grow vigorously.

The place Han Ninggui took them to was not steep, but because few people came to the mountain, it was not repaired and it was not very easy to walk until the road turned around and a small stream appeared again on the edge of the mountain forest.

Walking along the creek, it was much better than before.

However, there is a lot of moss on the shady side of the stream and it is slippery, so naturally you have to go to the sunny side.

"You can't see anything from this place. There is running water and the location is open. It's not as closed as it says. Why is there miasma here?"

Chen Ling took the dog with him and the kite was flying in the sky, but he didn't feel anything was wrong.

Han Ninggui nodded: "Well, there must be other reasons for this situation. If it has nothing to do with the terrain, it is probably because there are special minerals in the valley over there. Isn't there a mine in Gucheng County to the north of you?"

"Yes, we call Gucheng County Bastard City. There are many mines. Mining began a long time ago. I heard that many strange things happened during the mining process, which is quite scary."

"But Uncle Han, you said there might be a special mine here that produces miasma. Isn't this the kind of radiation mentioned in the textbook?"

"Oh, you kid also knows about radiation, that's good...

When it comes to radiation, it doesn't have such a rapid effect on people or living creatures. You want me to say that the dog walked around in the valley and foamed at the back.

It only lasts ten minutes, how can the radiation be so fast?"

"Oh, that's true."

We followed the stream upwards, twisting and turning, and finally arrived near the valley.

This valley is not too big and the location is very ordinary and gentle.

Wild trees, wild vines, and wild grass are no different from anywhere else.

But as soon as they got within about twenty meters of this area, the two dogs of Chen Ling's family suddenly stopped and started barking towards the valley.

As soon as they started barking, all the hunting dogs started barking after them.

Not only were the dogs barking, but the kites were circling and falling from the sky, refusing to enter the valley.

Such strange reactions of dogs and eagles.

It makes people's hearts skip a beat, and makes people who come to see something strange become cautious.

Han Ninggui stopped, looked at everyone, and said, "It was the dogs and eagles from the wealthy family who noticed the difference in this place. When we came here, the dogs didn't have this reaction."

"I also told you on the way here that when people enter the valley, they should cover their mouths and noses with clothes and try not to breathe hard."

Everyone nodded in agreement.

Professor Han and Feng Yi have already tried it. If they stay at the edge of the valley for a while, they will suffer from vomiting and diarrhea when they return.

Although it's not like a hunting dog foaming at the mouth, it's still more serious.

Everyone did not dare to be careless and followed carefully into the valley.

In fact, there were also some who were afraid and didn't want to go in, but they couldn't suppress their curiosity and followed in fearfully.

Chen Ling followed at the end and said jokingly to his two big dogs: "There is nothing to cover your noses, so just stay outside and come in to save us if anything happens."

The two dogs lied down outside the valley obediently, guarding there with a group of hunting dogs.

This made everyone laugh for a while, and at the same time, their nervous mood was relieved a lot.

However, everyone tried their best to speak less and breathe lightly.

Covering his mouth and nose with his sleeves, he walked into the valley and looked everywhere.

The valley is not big, with wild trees, vines, weeds and various types of plants very luxuriant. When you walk into the valley, you will feel a sense of coolness and greenery. Standing on the outer edge of the valley, you can hear the sound of water flowing outside the valley without feeling any discomfort.

feel oppressed.

But soon everyone discovered that the vegetation in this valley was extremely lush, but there were not a single bird or small animal, nor were there any snakes or mice. There were only all kinds of bugs, both crawling on the ground and flying in the air. There were quite a lot of bugs.

There are many bugs and lush plants, but no animals.

No, it's not nothing. After walking forward for nearly a hundred meters, there was a deer lying in the grass.

It's just dead and corrupted.

You can smell the putrid smell even if you cover your mouth and nose with your sleeve, it's very suffocating.

The group of people walked forward and once again found some scattered bones of wild beasts and mountain birds. Sometimes, it was so long that only the white bones were left.

They probably came here to graze or broke in by mistake. As a result, this place was not suitable for them. They were poisoned and couldn't get out, so they died here.

Apart from insects, there were no traces of all kinds of mountain birds and beasts, which made some hunters feel frightened when they saw it.

This valley is indeed a bit evil.

After walking around in a circle, some people covered their mouths and noses and felt slightly dizzy, so they all retreated.

After I retreated outside the valley and breathed in the fresh air, I felt like I felt better again.

"It's not that there is miasma, why can't you see it in the valley?" Liu Guangli, an old hunter, had never seen this miasma before. He thought that miasma was similar to fog, but he didn't see anything.

"It's really not there during the day, and it's no different from the outside. But at dusk, you can see it, and it's almost the same as fog."

Han Ninggui looked around at everyone and said, "Lao Feng and I have never gone deep before. This time we all dared to go in and take a look if we had someone to look after us.

However, it seems that the protection is good now and there will be no major problems in a short period of time after entering.

In this case, we can do the rest by ourselves, and you don’t need to take risks."

It was useless for others to follow the valley. They didn't understand this stuff and couldn't help them much.

But they are not completely unnecessary.

They still need to catch some birds and animals from time to time and bring them into the valley for experiments.

Others also need them to escort people in the mountains and serve as guides and bodyguards.

It doesn't mean they go back.

For most people, as long as they have money, it is not a problem, and they can still hunt by the way.

Chen Ling didn't care, he was not interested in this miasma or anything.

He followed them to the mountains because of the leopards and wild boars.

Leopards especially come first.

His mind was now focused on looking for leopards. When he was driving towards the valley, Wang Lixian found another footprint left by a leopard not far from the water. However, it had been a long time and the smell was no longer obvious. This was a sign of cold weather.

Even if the dog is missing, it will still be a great test for the dog.

It doesn't matter whether my two dogs are hot or cold.

But a leopard doesn't stop in one place and doesn't move.

Like the wild boar, it has its own main animal path and sub-animal path.

This is the so-called main diameter and branch diameter.
