Ling Xiao cautiously walked to the side of the hay shop laid by the Hu brothers, and did not reach out to bang anything, but carefully observed. The Hu brothers were suspicious of everything they had come into contact with, especially where they slept and ate.

Firewood, rice, oil, and salt are all normal foods, and there will be no problems. The two plastic buckets contained clean water, but they had not been tested, and if you look at them with the naked eye, you can't see anything wrong. As for the iron pot, it is also an ordinary iron pot, and there will be no problem.

Ling Xiao took out the plastic bottle used for sampling, carefully filled a bottle of water, and then sealed it in a sealed bag and put it into his backpack. He couldn't see what was wrong with the water, but the expert group led by Yang Yun had the equipment to analyze the composition of the water, and if there was any problem, the expert group would find out.

Ling Xiao's gaze fell on the hay-paved floor again.

The grass on the grass paved is not the common pasture grass on the grassland, nor the thatch common in the mountains, but a very special kind of grass, which looks soft and has long leaves, at least three feet long. It's still blue-yellow in color, not particularly dry, and apparently hasn't been cut for very long.

"What kind of grass is this, why haven't I seen it?" Ling Xiao thought with a frown.

He carefully grabbed a piece of grass with his hand wearing anti-bacterial gloves and gently twisted it with his fingers, and it was indeed very soft, softer than the straw used by the villagers to make beds. This kind of grass is used to make beds, but it will be very comfortable to sleep on, which is probably the reason why the Hu brothers chose this kind of grass to make beds.

At this moment, a strange smell suddenly reached his nostrils.

It was a decomposing smell of corpses, and it smelled terrible.

This unpleasant smell suddenly made Ling Xiao nervous, his first thought was the smell of this grass, but in a blink of an eye, if this kind of grass was so stinky, would the Hu family brothers still use it to pave the floor? With this thought, his heart settled down again. He followed the smell for something that stinked.

At the edge of the bunk, a mouse came into his sight.

The corpse of the rat was decomposed, but not of normal nature, its fur had fallen off, and its well-preserved skin was full of festering wounds. The rat had a rotten hole in its abdomen, and the internal organs could be seen from the hole opening, and its internal organs were also festering.

This discovery made Ling Xiao suddenly excited, "Isn't this a symptom of ghost burning?" Rats are also sick, is it related to these grasses? ”

There is no evidence for this inference, but it is extremely probable.

The Hu brothers slept on this bunk and contracted the disease, which is very likely.

The rats came to steal the rice oil stored by the Hu brothers in the rest point, and they liked the comfortable environment in the straw shop, but they also contracted and died, which is also very likely.

This is inferred, and all that remains is to take samples and go back to study.

Ling Xiao told Tang Meiyu about his discovery, and Tang Meiyu was also very excited.

"You didn't really find the source, are we going back?" Tang Meiyu was really reluctant to go on this expedition. There were so many fond memories of this expedition for her.

"It's time to go back, but we should check around this break. I suspect that the oni burn body is related to this grass, but this is only a guess and there is no evidence to prove it. We should look around to see if there is any such grass growing. I don't think the Hu brothers will go far to cut the grass to lay the ground, this kind of grass should still grow nearby. Ling Xiao said.

"Well, we'll take a look around the neighborhood. I don't see it, but your mind is quite thoughtful. Tang Meiyu said.

Ling Xiao smiled at her, then packed the grass in his hand in a sealed bag and put it in his backpack.

Before leaving, Tang Meiyu took her SLR camera to take two photos of the Hu brothers' floor and the corpse of the mouse. These photos will make Ling Xiao's inference more convincing.

Leaving the cave, Tang Meiyu returned to Ling Xiao's back again, and he carried him around the mountains and forests. She really enjoyed the process of being able to explore in the mountains and forests without her feet, and the sense of security that Ling Xiao brought her. She took a camera to take pictures of the beautiful scenery in the mountains and forests, and sometimes she would give Ling Xiao a photo, individually, in a group photo.

Her restlessness caused Ling Xiao to face a problem in addition to searching for mysterious weeds, and that was the feeling she gave him from moving around his back, which was what gave him a headache. Still, he had to endure it.

After taking a turn around the third rest point, Ling Xiao found the grass used to lay the ground in the cave on a slope. Looking at it in the cave, he saw the blue and yellow colors because it was not natural light. Now looking at the meadow in the sun, it is a little black, cyan, yellow and black, which makes up a special gloomy tone. It was like a plant from another world, alienated from the trees and weeds around it.

The area of the grassland is not large, only a few points of the area. There are marks of cutting on several corners of the meadow, some of which are fresh and the roots are still fresh, while others have been around for a long time and the roots have withered.

This discovery made Ling Xiao confirm the inference in his heart.

Initially, a hunter in Xiama Village or a villager who had crossed the snowy mountains to dig Cordyceps discovered the grass and used it to lay on the ground. This villager or hunter was infected with the oni-burning virus, and when he returned to the village, the oni-burning virus was transmitted to others. The Hu brothers and the hunters of the Chen family did not know that this grass was a deadly thing, they knew about the existence of this grass from other hunters and villagers, and they also spread this grass on their rest points, so they could not escape their doom.

Rest points and floor shops are very primitive in the eyes of more professional travelers like Ma Tie or Tang Meiyu, and there is no need, because they are all professional outdoor tents, and they are not much bigger than an umbrella when put away, just put them in the backpack. But the villagers of Xiamazhai do not have such conditions, they hunt in the mountains, digging cordyceps on the grassland, often taking more than 20 days or even more than a month at a time, which is a long time, they must build their rest points to guard against the sneak attack of wild beasts. With a rest, it's normal to find a way to make yourself comfortable.

But I didn't expect that this would become a nightmare for the entire Hongxiagou.

There are some earth-shattering big times, and the cause of it is often unexpected little problems. This seems to confirm the old saying, there are unpredictable circumstances in the sky, people have good and bad luck, the world is unpredictable, and everything has its own destiny.

"What kind of grass is this? So evil. Tang Meiyu sighed on Ling Xiao's back.

Ling Xiao shook his head, "I don't know what to do, but with this grass sample, the expert group will be able to overcome the virus, and this crisis will pass." ”

"Let's go back." Tang Meiyu said that although she was reluctant to end the expedition, she also knew that it was more important for her to send samples of the grass to the expert group.

"Well, just go back." Ling Xiao said, but the person didn't move, still observing the grass.

This meadow is really spooky.

Other meadows, often grow several kinds of grass, and vines or something, but this meadow only grows this kind of grass, there is no other grass, no vines or anything, it is very pure, this hillside is like their territory. On the ground, there is not a single ant or other insect in sight, it is completely a place of living death.

"Ling Xiao, what are you looking at?" Tang Meiyu said curiously. The source has been found and samples have been taken, what is he still doing in this dangerous place?

Ling Xiao's gaze fell on top of a grass, which had already bloomed. The black flowers, small, like ears of wheat, are densely crawling with the stems. Those little flowers are so inconspicuous, and they look very weird.

Tang Meiyu also saw those small black flowers, her heart moved, raised her arm, and took several photos of those flowers.

"You wait for me, I'll pull that grass back." Ling Xiao said and put Tang Meiyu down.

Tang Meiyu stood on the ground with one foot and said with concern: "Ling Xiao, be careful. ”

Ling Xiao nodded, cautiously walked to the edge of the grass, and pulled up the flowering grass. Then he folded the grass in half, put it in a large sealed bag, and carefully packed it into his backpack. The backpack also contained the snow lotus he had picked on the snowy mountain when he came, and at this time he took it out and threw it into the grass. With such a dangerous and evil thing, although there is a sealed bag, he doesn't plan to ask for that snow lotus anymore.

"Alright, let's go back." Ling Xiao walked back, squatted down, and waited for Tang Meiyu to climb onto his back.

Tang Meiyu even leaned forward, her arms naturally wrapped around his neck, and then her legs were spread apart, clamping his waist. She is already very proficient in these movements. With such intimate contact, she doesn't feel shy anymore, it feels natural.

Ling Xiao let go of his hands, dragged her hips, and then stood up with his feet propped up.

"Go home!" Tang Meiyu roared excitedly.

Ling Xiao was feeling her delicate and fat buttocks, and a smile appeared on the corner of his mouth.

"By the way, Ling Xiao, can those experts overcome the Ghost Burning Body Virus?"

"I don't know what to do, I think it should be possible, the technology is very developed now, with samples, I think it should be possible." Ling Xiao said that he felt that the chances of success were still very high.

"I don't know if Lu Dao can save the Hu family brothers, they are so pitiful, they are still so young, if they die like this, their family will not be able to accept it."

"I hope we can, we need to go back soon." Ling Xiao suddenly hugged Tang Meiyu's fragrant buttocks.

"Yikes!" Her buttocks were suddenly violated, and Tang Meiyu's face turned red all of a sudden, and she became nervous.

Ling Xiao suddenly started and ran in the mountains and forests!

"You-" Tang Meiyu's mouth opened wide in excitement, she couldn't believe what she was going through—he could still run in the mountains and forests with a person on his back, and he was very fast!
