After being buried for a period of time, those animal carcasses will be rotten and smelly, and it is also now. I just came here. It is obvious that these dead cattle and sheep have not been deeply buried at all.

Even without the use of lime for disinfection, I just got off the car and smelled a disgusting smell.

How unpleasant are rotting animals?

This is indescribable.

When Ye Chen got out of the car, the two soldiers from Battelle also got out.

After Liu Jing and Wulan put on their masks and got out of the car, they still wanted to vomit directly when they smelled the rancid smell.

This smell is really uncomfortable!

The two women hurriedly got into the car, and Xia Qi couldn't stand it just now.

Now the two Mongolian soldiers and the Mongolian guide Bilge followed.

And the herder from the ranch followed.

When he just arrived there, Ye Chen discovered that the dead cattle and sheep here were simply covered with mud, which caused a lot of smell to be emitted directly.

Because the temperature here during the day is ten or twenty degrees, there is still the sun, if it is at night, the temperature is very low.

However, under the effect of daylight exposure, these cattle and sheep carcasses are more susceptible to rancidity.

When the two soldiers were shoveling off the dirt on the top, the dead cattle and sheep were exposed, but now there are many maggots crawling around, and the red bugs are on the animals. Climbed in on the corpse.

These disgusting maggots.

In addition, after the soil and turf on the top were scooped away with a shovel, the smell of rot and rancidity made people feel even more disgusting.

When the two Battelle soldiers were a few steps backstage, Ye Chen took out his mobile phone and took pictures there.

Those maggots, Ye Chen knew that it was those flies that lay eggs, and then absorbed nutrients on those animal carcasses and grew up. Before they could fly, they would become these disgusting wriggling maggots.

In addition, those red bugs, Ye Chen didn't know what they were, they should be something that decomposes animal carcasses on the grassland.

Ye Chen called to the guide and asked, "What is this?"

"This is the kind of red bug."

"Aren't they decomposing animal feces? Why are they all on these cow and sheep carcasses now?"

Ye Chen asked.

Like those **** shellers who eat shit, it is impossible to eat grass or meat, and if they eat it, the body can't digest it.

If these red bugs are used to decompose animal feces, they should also use feces as their main food. How can they now appear on animal carcasses?

At this point, Ye Chen was a little confused.

Moreover, Ye Chen found that this kind of insects looked a little scary, densely packed.

Ye Chen turned around and got into the car with Bilege. In the car, he hurriedly drove away from here, but Wulan had already called to inform people to come here to deal with these dead animals.

"How did the animal carcasses on the grassland be cleaned up?"

Ye Chen asked.

"Of course nature cleans it up."

Nature cleans up by itself?

"In the past, there were many wild wolves, foxes, even vultures and eagles on the prairie, which would eat the dead animal carcasses."

The biological chain on the prairie.

In fact, Ye Chen had already seen it in his senior year of high school before.

Like the simplest biological chain on the prairie, rabbits eat grass, and then wild wolves and eagles eat rabbits.

There are cattle and sheep eating grass, wild wolves and beasts eating cattle and sheep, and their dung is fed back to the prairie.

There are rats on the prairie eating grass, then snakes on the prairie eat mice, eagles on the prairie eat mice, and so on.

Of course, this prairie is also a separate animal and plant ecosystem, but these are only the most basic and basic biological chains.

Because with human participation, in fact, the biological chain and even the ecosystem on this prairie are completely different.

Even because of excessive human intervention.

Including overgrazing, leading to desertification on the grasslands, and then leading to larger and larger deserts on the prairies.

In addition, animals such as wild wolves on the prairie are over-hunted by humans. As a result, animals such as wild wolves and foxes are probably rarely seen on the prairie now.

Therefore, Ye Chen felt that this kind of plague could not have appeared on the grassland for no reason, it must be the rebirth chain, and even in the ecosystem, which aspect had problems.

Recalling the corpses of cattle and sheep just now, Ye Chen seemed to think of many questions.

If it were these animal carcasses, they would not be decomposed by nature itself as before.

Like not being eaten by those wild wolves, vultures and other animals, it must take a long time to break down after so long.

Then does it produce any viruses or bacteria?

And how does this virus and bacteria infect those livestock and even herders?

Ye Chen didn't know, but he always felt that it must be related.

"Are there many mice on your prairie?"

"There are mice, and there are groundhogs."

Groundhog?

Ye Chen had heard of it, but he hadn't really seen it yet.

As for mice, this species seems to be everywhere, as long as there are humans. After all, these mice can eat everything, human feces can be eaten, animal feces can also be eaten, and even those young grasses and roots can be eaten.

In this case, those mice must have reproduced in large numbers.

And mice also carry a lot of viruses and bacteria, especially like those in the city's sewers, and more.

Now Ye Chen asks people to take those red bugs, mice and even feces, and then they will bring them back to the people to study and see where the virus and bacteria are carried, and even where it first spread. from.

"The marmot, also called the marmot, likes to burrow in the ground. The herders don't like it. They like to destroy the turf, and they eat everything."

"The mouse on the grassland, what kind of animal eats?"

"It used to be foxes, yellow ferrets, and eagles to catch and eat, but nowadays foxes, yellow ferrets, and eagles are rarely seen."

Like a yellow weasel, that is, a weasel, Ye Chen remembered that in China, most people would not dare to fight this weasel. They thought the other side was a very evil animal. Of course, it is rarely seen in China now.

However, wild foxes, weasels, and eagles are all protected animals, and naturally few people dare to hunt them.

However, it doesn't seem to be the case in Mongolia, and there are still many people fighting, resulting in fewer and fewer animals.

"What about the wild wolf? I have just been in the car for such a long time, how come there are no wild wolves?"

Ye Chen asked strangely.

"Maybe ten years ago, there were still a lot of wild wolves, but now they are basically hunted and killed. The government and herders organize the killing because they steal the cattle and sheep of those herders in groups," said Bilge.
