Don't look at these things buried in the dirt, they are basically like they have disappeared, but in fact, they have a lot of origins.

Xu Yang remembers seeing this thing at his grandmother's house when he was a child, and in the mouth of the old Chinese medicine doctor in the village, this thing is called luminous sand, a traditional Chinese medicine prescription that has a regulating effect on malaria!

Malaria usually comes from bats, and luminous sand poop is also the feces of bats, which is similar to what Xu Yang thought of, there must be a solution within seven steps, so he hurriedly stepped forward to pick up these things, whether it works or not, it is a good medicine, maybe it will work for her Qin Xiaoyun?

Moreover, Xu Yang has been thinking about a possibility, if it is highly toxic, or a poison that can cause some kind of emergency illness, Xu Yang may not have thought of this, but since it is a chronic complication, and traces of bats have also been found, then Xu Yang will inevitably think of bats, after all, there are nearly 4100 viruses on bats, such as Ebola, rabies virus and SARS, etc., which are stored in bats, so rare diseases such as purple protein disease, Xu Yang was easily connected with bats!

Since the source of the disease also comes from bats, these luminous sands may also be symptomatic, and the probability is very high, and there are no signs of other plant growth here, eliminating other possibilities, the antidote to treatment is also clear, it is a multiple-choice question!

This is the reason why Xu Yang is excited, because he seems to have found a way to save Qin Xiaoyun, which is great news for him!

Qin Xiaoyun discussed with Xu Yang the deeds recorded in the Bing diary, she used many methods to save her man, but basically she was working hard in the direction of concocting serum, so it has been two years, and she has not seen any good, but she never thought that the ancestor had already announced the method, she never thought that the answer was around, and she would not have thought that the antidote might be the feces of a certain object...

It's really pitiful and pathetic to think about.

"It should be almost, while the flashlight is still strong enough to last a while, I have to go back quickly." Xu Yang muttered as he picked up the somewhat sour luminous sand.

Once they were all in the second compartment of his backpack, he was about to turn around and go back.

But just when he dared to move, suddenly his eyes began to shake, Xu Yang thought that he was wrong again, until the falling rocks on the top of the cave fell and fell, he didn't realize that it was really an earthquake!

And with a burst of swaying and swaying, Xu Yang heard countless hula hula sounds, Xu Yang immediately realized something, and immediately broke out in a cold sweat, and immediately squatted down with his head in his hands, curling up in the corner as much as possible!

Soon, countless bats flew past behind Xu Yang, and because the space was too small, the sound of bats' wings flapping could be heard as loud as thunder, and it was continuous thunder!

Xu Yang was helpless, if the space was a little larger, he might still be able to think of a way to dodge it, but the space was too small, how could he, a two-legged monster on land, compare with the speed of a bat with wings? Curling up in one place, and trying to wrap your clothes and back around the flesh and skin, and reduce being bitten and scratched, is already the greatest protection for yourself...

This is also a way to no way, he is betting that the bats have no malicious intent, after all, as far as he knows, bats do not attack people easily, unless someone provokes them, but Xu Yang just picked up a few of their feces particles, which is not offensive to them, and should not be sucked to death...

Of course, this possibility is not ruled out!

And just as Xu Yang hugged his head tightly, and after about a minute or two of pretending to be dead, the sound of flapping his wings faded away, Xu Yang raised his head carefully, looked into the distance, and took a little light with a flashlight, and found that they were all flying far away, speaking of which, this flight speed should be considered fast in bats!

Although he was surprised, Xu Yang couldn't care so much, the first thing after he was safe, he quickly took a flashlight to shine on the back of his hand, and touched the skin that might be injured on his body, but fortunately, he didn't see anything abnormal, as if the wind passed without a trace...

This couldn't help but make him scratch his neck and mutter, "It's strange, there is no intention to attack at all?" Could it be a fruit bat, a vegetarian? It doesn't look like it, and it's not tropical..."

In addition, since these bats didn't come out to attack him Xu Yang, why did they all fly to that end?

There are only two reasons for bats to go on patrol, one is to forage for food, and the other is to avoid natural predators, and the former is excluded, and it seems that only the latter is left...

Generally speaking, bats are natural enemies such as lizards, birds, snakes, etc., and it seems unlikely that there is an ecosystem here that can give birth to these creatures, but if it is not, what would it be?

For a moment, he thought of the inexplicable shaking of the mountains just now, and an idea made him suddenly break out in a cold sweat...

Beep!

It was Liu Yue's whistle, Xu Yang hurriedly put away his thoughts, and muttered: "No matter what, it's important to get down to business, and it's okay to leave here." ”

Soon, Xu Yang hurried back, but saw that the two girls were fine, and asked the reason for the whistle, Liu Yue said that he was frightened by the earthquake, Xu Yang explained that it was no big deal, the cave was very strong and would not collapse easily, and after appeasement, he hurriedly took out the antidote he found, Liu Yue had studied medicine with her father after all, and she could see what it was at a glance.

After all, in her Liu Yue's eyes, Qin Xiaoyun can only be a character with fine clothes and fine food, how can she eat that?

Qin Xiaoyun was a little sober at the moment, probably also learned about her condition from Liu Yue's mouth, so when she talked about the antidote, she was not confused, and she glanced at that thing, smelling extremely sour, and couldn't help frowning...

But, after all, she is Qin Xiaoyun, a person who has been a female president, she understands that dignity is useless at this moment, and what is more important than dignity is a matter of survival!

Therefore, she still bit her thin lip, and did not care about Liu Yue's admonition, but stared at Xu Yang and said, "Brother Xu, I believe in you, feed it to me." ”

"Mr. Qin, that thing is..."Liu Yue was about to say, but was glared back by Qin Xiaoyun.

"No matter what it is, I believe that Brother Xu will not harm me, he is desperate for me, is it still unwilling to give me this trust? Then I, Qin Xiaoyun, am really a joke... I don't care what it is, all I know is that it's the medicine my man used to save me, that's all, you don't need to say more. Qin Xiaoyun said categorically.

Hearing Qin Xiaoyun say this, Liu Yue could only sigh and take the words back.

Xu Yang admired it in his heart, Qin Xiaoyun, an elite human being, this pattern should really be opened, if it weren't for this, he Xu Yang didn't know how much effort it would take to persuade her to obey!

But Xu Yang is also a bit vain, after all, the inference is definitely effective, but the actual effect, he can't guarantee it, but this attempt is necessary...

Therefore, he could only beg in his heart, and then he found one, stuffed it into Qin Xiaoyun's mouth, and said, "Eh, swallow it directly... Don't choke your nose. ”

Qin Xiaoyun had great trust in Xu Yang's field ability, and she didn't think much about it, so she swallowed it with a bang...

She gasped and coughed slightly, Liu Yue hurriedly stepped forward to give Qin Xiaoyun a pulse, and opened her eyelids to look at the bottom of her eyes, probably checking the state of the blood vessels under her eyes to confirm her condition, and then checked the look of her eyes and skin, and touched Xiaoyun's forehead and neck, etc...

To be honest, Xu Yang is a little nervous, and his mentality is like that of a primary school student who has submitted a test paper... Fortunately, after a while, Liu Yue sighed, and couldn't help but give Xu Yang a thumbs up, and said, "The symptoms have subsided, Xu Yang, count you as amazing!" ”

Qin Xiaoyun just smiled indifferently at the result, but Xu Yangke was so excited, he got up and patted his chest and said proudly and happily: "That's not it, Cheng Bing's illness that hasn't been done for two years, I have done it, I admire myself, hahaha!" ”

"Indeed, it was clear in the diary that she couldn't do anything... Well done, Brother Xu! Qin Xiaoyun also smiled, even if she was a little sick, but her smile was brighter than usual, and there was a unique beauty, Xu Yang couldn't help but be stunned again...

Seeing this, Qin Xiaoyun couldn't help blushing a little, and hurriedly said, "Okay, go back and take a slow look, I just praised you for two sentences and got carried away?" Help me untie it, and then we'll all figure out how to get out. ”

Xu Yang was right to think about it, it's not safe here...

But fortunately, the exit was probably found, the direction of the bat swarm just now, probably the exit location, after all, there is danger in the hole, they must fly outside the hole, and when they feel safe, and out of habitat instinct, they will come back, this is the law of bat habitat.

So, he hurriedly untied Qin Xiaoyun's bound hand, and then he took the torch to lead the way, and the girls supported each other and followed behind...

After making sure that the direction was correct, Xu Yang couldn't help but lead the people forward, and finally, after walking for nearly half an hour, they finally saw the white light of the morning light!

Stepping up, they trotted with their heads down, and finally rushed out of the cave, ushering in the dawn and fresh air!

However, when they were so excited and their eyes slowly adjusted to the bright world, all three of them stood stunned at the same time...

Unexpectedly, the place where this crypt came out was actually in the ruins of the siege, and you could see the camp where the smoke was curling not far away!

For a while, Xu Yang turned his head to look at the open crypt mouth, and couldn't help but think a little more...

Especially when I think of the strange mural content I saw in the cave not long ago!
