I was slightly stunned when I heard Yu Pu's request, and I thought I had heard it wrong.

"Digging bugs? What's the use of digging these things? I frowned, my scalp tingling at the thought of the dense mass of bugs.

The others also had the same doubts, and for a while no one made a move, they all looked at Yu Pu and waited for him to explain.

But I didn't expect that Yu Pu, a person who has always given me a calm feeling, walked directly to the tree after seeing that we didn't move today, knelt on the ground and dug it with his bare hands, without even taking a branch.

Everyone seemed to be startled by Yu Pu's movements, and no one spoke for a while, just looked at him in shock or confusion.

Since I was squatting next to the tree, when Yu Pu dug up the soil, the scene exposed in the soil was also clearly reflected in my eyes—it turned out that the soil was only a layer on the surface, and it was densely packed with all kinds of insects.

I watched Yu Pu's hands into the soil mixed with a large number of insects, as if I felt that I had also touched those dense insects, and I couldn't help but feel a kind of itching, starting from my hands and spreading all over my body, as if there were countless insects crawling on my body.

As soon as this feeling appeared, I immediately got up and took two steps back away from Yu Pu's side, while rubbing my arm to brush off the bugs that didn't exist.

No, no, I really can't stand this visual impact, even if I know it's a psychological effect, but I still can't stop this itching sensation that seems to be crawling all over my body.

I took two more steps back, narrowing the distance a little further, and deliberately avoided looking at the digging place, focusing only on Yu Pu's face.

Yu Pu's face was still expressionless, just staring at the place in front of him, and it was obvious that he could feel a kind of concentration.

But what to focus on? Focus on digging up bugs? Or do you focus on digging holes? I really don't understand.

"Mo Mo Li?" Hearing the voice, I turned my head to see that it was Fang Ruoxi who came to my side, "Mo Li, what is Yu Pu doing?" ”

I looked at Fang Ruoxi, then turned my head to look at Yu Pu, and shook my head silently.

What is Yu Pu doing again? To be honest, I'd love to know too.

I turned my head to look at the others again, Lu Haisheng and Lin Ya were standing behind Yu Pu, thinking that they were not so afraid of insects, but they didn't go up to help. On the other side, I quickly took a look at the demeanor of Fu Lingjun and the other five people.

Fu Lingjun looked puzzled, as if he wanted to get closer to see what Yu Pu was doing, but he showed a look of disdain and inspection.

Wang Haobo's face was obviously ridiculed and contemptuous, and what was being said to Chen Si who was hugging him, it could be seen from his expression that it was definitely not a good word.

And Chen Si didn't look at us, I could only see her side face, and I couldn't see any emotion.

The remaining two people, Lin Chang and Li Sheng, both seemed to be paying attention to Yu Pu's actions, curious and thoughtful at the same time. It's just that the difference is that Li Sheng's face is a kind of calm thinking, while Lin Chang always makes people feel ill-intentioned.

"Oh my God! This is!!! ”

Fang Ruoxi's exclamation brought me back to my senses, and her voice was full of surprise. I instinctively reacted that this must be something new on Yu Pu's side.

Turning my head to look at Yu Pu, I also exclaimed in an instant. Not because of the embarrassment he dug up in the dirt, nor because of the piles of crawling insects in the pit, but because I saw the water in the pit.

Water! Headwaters!

The surprise made me forget my dislike of insects, and walked back to Yu Pu's side in three or two steps. As I got closer, I saw more clearly that water was indeed gushing out of the dug pit.

For a while, I didn't even care about the insects in the pit that were active and crawling because of the water, so I reached directly into the small puddle overflowing in the pit and dipped it. After retracting my hand, I raised my hand and put it under my nose to sniff, there was no peculiar smell, and most importantly, there was no sour smell of nitric acid.

"Is this clean water? This is the water source!? "The surprise made my voice a little out of tune.

"It should be."

Yu Pu's voice attracted my attention, he carefully took a handful of water without insects in the puddle, then stood up from the ground, also held it to his nose and sniffed, "There is no smell, if my inference is correct, this is clean, drinkable water." ”

"How did you come up with that? Is there any reason to say that the water is clean? It was Lu Haisheng who asked the question, and he also walked closer to Yu Pu, and cast his eyes on the handful of water in Yu Pu's hand, "Those insects have been soaked in these waters, and those insects can move freely in the nitric acid rain without being affected." How can you assume that the water is clean? ”

"That's right." Lin Ya also frowned and said, "There are so many insects soaked in this water, and the source is not clear, how can you be sure that it is clean?" ”

Yu Pu thought for a moment when he heard Lu Haisheng and Lin Ya's words, and then looked at the pit that had been dug. I followed Yu Pu's gaze and found that the water that had just overflowed in the pit was still there, but the insects in the pit were gone, and only the dormant insects outside the pit that had been dug out and had not touched the water were still there.

"What about the bugs?" I couldn't help but muttered to myself.

"I saw that the bugs were all going into the soil at the bottom of the pit, very fast, in a matter of seconds."

When I heard Fang Ruoxi's words, I turned my head to look at her, and Fang Ruoxi nodded at me, confirming that what she just said was the truth. At this time, Yu Pu also said again.

"This water is supposed to be rain." Yu Pu explained to us, "It's just that this should be filtered rainwater. ”

Lin Ya said in surprise: "Filtering? What is filtered? ”

"Bugs." Yu Pu said in a deep voice.

"Bugs?" I can't help but repeat.

"Yes, bugs." Yu Pu nodded and continued to explain, "I've been wondering how the trees here are not affected by nitric acid rain. The leaves are resistant to nitric rain because of the waxy surface of the trees, but these trees always have to absorb water, so how do the roots resist the nitric rain that seeps into the ground? ”

I followed Yu Pu's train of thought and thought, "If the roots of the tree are also covered with wax, then the roots of the tree will not be able to absorb water, and if there is no waxy surface to protect them, they will directly contact nitric acid and be eroded, right?" ”

"Yes, that's right." Yu Pu nodded, "So there must be a program that we don't know about, and this program allows the trees here to get water that can be absorbed." ”

"That program," Lu Haisheng muttered, "are these bugs?" ”

Yu Pu nodded again and explained in detail, "That's right, the program we don't know about is these bugs. According to my speculation, these bugs should not have come to life when they encountered water, but with nitric acid. You see, there was water in the pit, but the insects didn't stay in the water, but went deeper into the soil, because they didn't like water, but nitric acid. ”

I nodded, I felt that Yu Pu's explanation was very reasonable, thinking about it carefully, when Fang Ruoxi poured water into the pit before, those insects were indeed drilling deeper places.

With this, we can make an inference that the presence of these bugs absorbs the nitric acid from the nitric acid rain. Only pure water is left, which remains in the soil and is absorbed by the trees here, thus creating a special ecological cycle here. And this water should be clean water after nitric acid is removed. ”

"You make a lot of sense." Lu Haisheng looked down at the remaining water in the pit, "But this does not guarantee that this water is safe." Even if nitric acid is removed, there may be other impurities in it, and even if these impurities are ignored, there may be some kind of toxin derived from these bugs. After all, we are different from the trees here, and the water that the trees can absorb is not necessarily harmless to us. ”

I looked at Lu Haisheng, then at the remaining water in the pit and frowned, I have to say that Lu Haishen's worries are not unreasonable. Although the water looks clean and doesn't smell bad, who knows if there will be any colorless and odorless toxins in it? We don't dare to take that risk.

"Isn't that easy? Find someone to try! ”

Some unfamiliar voices came from behind me, and I turned my head to look, only to find that at some point, the five people had already walked not far behind me, just the distance from which I could fully see the situation.

It was Lin Chang who spoke just now, and I couldn't help frowning when I looked at him with bad intentions, and said in a somewhat impulsive tone: "Find someone to try?" Who to try it out? Are you? ”

"Hey, hey, beauty, are you kidding?" Lin Chang didn't seem to feel my unhappiness at all, and said with a hippie smile, "There are so many people here, look at my small body, no one can find me." It's not that whoever deduces it will take a sip and try it. ”

Who deduced who took a sip and tried it? What bullshit is this! It's ugly, but it's beautiful!

I glared at Lin Chang fiercely, completely sure of his idea that he was not a good person. However, what I didn't expect was that Yu Pu actually glanced at Lin Chang seriously, and then lowered his head and prepared to drink the handful of water in his hand.

"Hey!"

I exclaimed, and subconsciously reached out and knocked out Yu Pu's hand, knocking over the little water left in his hand.

Seeing Yu Pu looking at me, I was really angry, and glared at Yu Pu fiercely, "If he asks you to drink, you will drink?" Are you stupid? ”

"It's fine." Yu Pu said calmly, "I have confidence in my inference. ”

"That's not going to work either! What sound do you have? ”

Buzz buzz buzz

I was talking to Yu Pu when I suddenly heard a strange sound, and suddenly stopped talking, and listened attentively, but found that the sound was getting louder and louder, as if something was approaching.

"It's from over there." Fang Ruoxi pointed to the side and called.

I squinted and looked in the direction Fang Ruoxi pointed out, only to see a dark cloud drifting in the distance.

"That's running! Come on! ”
