"What's wrong?" Seeing that Xiao Tian suddenly sat up from the ground, Uncle Hu also hurriedly sat up from the ground. But following Yang Xiaotian's line of sight, Uncle Hu didn't see anything. Yang Xiaotian didn't sleep well, and Uncle Hu, who saw Yang Xiaotian suffering so much, was also sour for a while.

It's a good boy, and he really needs and values Roy. Of course, more importantly, this child did not bring grace to coerce him because of grace and gourd village. used his kindness to the village as a bargaining chip to blackmail him into handing over Luo Ai.

Not only that, but he still chose to continue entering the mountain in such a dangerous situation the last time. And compared with the preparation last time, the preparation this time is obviously much more abundant than the last time.

In fact, if it weren't for the inconvenience of private soldiers to use it to collect medicine for themselves, Yang Xiaotian would have thought about letting those powerful private soldiers also come over to collect medicine for himself!

Of course, it's okay to think about this matter a little, after all, the matter of collecting medicine is more of his own business, and it has nothing to do with the private soldiers.

The task of the private soldiers is more to cooperate with him in some violent missions. And something like this kind of medicine collection, I'm afraid that unless it is ordered from above, and it is required with a very serious attitude. Otherwise, this kind of crepe medicine collection thing, those arrogant private soldiers will never do it.

"Nothing, maybe I read it wrong. Yang Xiaotian shook his head in disappointment, a bright light flashed in the distance just now, and at the moment when the bright light flashed, Yang Xiaotian felt as if he had seen something flashing by. That thing is a small animal, and according to the records, the favorite food of that little animal is Roay!

"Bearded rats. Yang Xiaotian said the name of the animal, this animal, sexual joy and quiet, for a year, most of them live underground. On weekdays, they eat the roots of plants and trees most of the time.

In general, a bearded rat can survive for about ten years at most. Not because they don't live long, but because here they have their natural predator - snakes.

But snakes are afraid of realgar, and the smell of Luo Ai is very similar to realgar. What's more, if bearded rats can eat Luo Ai, then their bodies will have the taste of realgar.

This taste can last for at least a year. This means that unless they happen to pass by the snake's mouth, the snake will leave first if it smells the yellow on their body.

Bearded rats, because they live underground all year round, their eyesight has not deteriorated like moles, but has evolved more acute night vision.

Even at night, they can catch the light lit by a match from a kilometre away. And their noses, though not like moles, have evolved to the point where they can replace their eyes.

But the special taste of Roai has been deeply engraved in the genes of the bearded rat.

So if you can find the bearded mouse, you can basically find Roai.

Of course, because the bearded rat rarely appears, even the animal encyclopedia finds the existence of this creature - the reason why Yang Xiaotian knows about this mysterious animal is naturally because he has read the book for a long time in the back mountain.

If this is not the case, because there is a very important connection between this animal and Luo Ai, when he saw this animal, Yang Xiaotian focused on remembering it.

It's just a pity that because more than ten years have passed, Yang Xiaotian can't guarantee whether what he sees is a bearded rat or not.

"Bearded rat, did you see the bearded rat just now?" Unexpectedly, Yang Xiaotian's casual muttering was heard by Uncle Hu. After hearing Yang Xiaotian's words, Uncle Hu immediately showed great excitement.

"Uncle Hu, do you also know about bearded rats?" Yang Xiaotian looked at Uncle Hu in disbelief. He had seen the bearded rat in a medical book, and the bearded rat was listed separately as a guide animal to guide the search for Roai.

But Uncle Hu, this ...... Could it be that he is also a hidden medical holy hand?

But Yang Xiaotian quickly put this thought aside, if Uncle Hu was really the holy hand of Chinese medicine, he would not be helpless about his son's illness.

"Well, your grandfather once told me about the bearded rat. Uncle Hu's words made Yang Xiaotian feel relieved, but at the same time, he felt that this matter was not very reliable.

When I first saw this bearded rat, I saw it in a medical book more than ten years ago.

And now Uncle Hu knows the way of the bearded rat, which is even more unreliable than himself - he remembered the name of this mysterious animal through other people's telling.

In view of the fact that it was obtained in this way, Yang Xiaotian did not have much hope that Uncle Hu would be able to recognize the bearded mouse.

"The bearded rat has a body length of half an inch, a slender tail, and a slender body, but the whiskers on both sides of the mouth are like the beards of the big man, so it is called the bearded rat. Then what Uncle Hu said quickly made Yang Xiaotian's heart rekindle the light of hope again.

What Uncle Hu said was what he had seen in medical books. It's just that because of the age, he has forgotten it.

If it weren't for the fact that a herb was used, and the effect that this herb should have happened to be the effect of Luo Ai, I'm afraid Yang Xiaotian wouldn't even be able to remember Luo Ai!

As for the bearded mouse, if he hadn't just seen it, Yang Xiaotian probably wouldn't remember it in his life, and if he wanted to find Luo Ai, the quickest, most convenient, and most accurate way was to find the bearded mouse.

And looking for another herb that grows with Luo Ai - Bessis grass is actually not very effective.

Because although the distribution range of the bearded grass is slightly wider than that of the Roai, it is only a little.

If you can find the bearded grass, then Luo Ai is basically already within sight - the growth area between the two will not exceed three meters at most.

And the reason why Luo Ai grew so close to the green beard grass was naturally because of the bearded rat.

While snakes are afraid of the smell of Roai, they are not afraid of the smell of bearded grass.

The bearded rats knew that Luo Ai was an important means for them to evade the snakes, and the snakes naturally knew that if the bearded rats wanted to avoid their pursuit, they had to come to Luo Ai's side.

And the bearded grass snake is not afraid of its smell, but because snakes often swim on it, there is basically the smell of snakes on the bearded grass.

The smell of this natural predator, once it is smelled by bearded rats, they will naturally become vigilant immediately.

This is the principle of mutual symbiosis - Roai can use the smell of snakes on the tourmaline grass to hide from the gnawing of natural predators. On the other hand, the bearded grass can absorb the nutrients from the feces excreted by snakes after killing a large number of bearded rats, and at the same time live a better life.

Roai is a bait to attract bearded rats, but even so, the number of snakes is not comparable to that of bearded rats.

What's more, bearded rats usually live underground, and rarely appear above the ground. And the underground location where they live is about three meters underground.

Bearded rats are natural burrowers, and their paws can change from soft to hard from the first week of birth.

But at the end of the day, animals know they can't just catch their fish. The main roads in which they burrow are avoided by trees and grass cover.

On the one hand, in this way, the channels they dig do not affect the growth of the plants, so that they have enough food sources that will not be depleted.

On the other hand, it is because, if they dig too hard and cause the vegetation on it to wither, their natural predators, snakes, will detect their tracks.

And Heaven is fair, it has given the bearded rat a keen sight and a sense of smell that is not inferior to that of the mole. But its mobility is not particularly good.

On the one hand, they live underground, and the passages they build can be used for many years. This is the predecessors planting trees, and the descendants enjoying the coolness.

Therefore, there is a certain pattern in the exercise ability of bearded rats.

After getting Roai, because they have the smell of Roai, they don't need to rely on hiding underground to avoid snakes every day like before.

After that, from the ground to the surface, their ability to move is much stronger.

After a year, when the smell of Roai had dissipated, they had to hide underground again. And because of the improvement of athletic ability, their ability to dig holes will naturally also improve.

And the hole that has been dug can last at least until the next time Luo Ai matures......

For only one year in thirty years, bearded rats will frequently appear on the surface. So it's really not easy to investigate this mysterious animal.

Could it be that ...... "The appearance of the bearded mouse is really too special, although it was just a flash just now, but Yang Xiaotian is basically sure that the little thing he saw just now is the appearance of a mouse."

Add to that the specially-shaped whiskers on either side of its mouth!

"Everyone, hurry up and pack your things, let's go over there and have a look!" Luo Ai was so important to Yang Xiaotian that Yang Xiaotian even trembled a little in the tone of his voice after determining the trace of the bearded rat.

"Okay!" Although they didn't know why Yang Xiaotian was suddenly like this, since Yang Xiaotian had already said it, they naturally did it. After all, whether it is strength or prestige, among these people, Yang Xiaotian is the one who is the highest.
