What's going on? Everyone started to get nervous.

Chen Jiaoyang pointed at the group of glowing fireflies with his finger and said vigilantly: "Look, there is something wrong with this group of fireflies. ”

Everyone looked at Chen Xiangyang's fingers, and there was indeed something strange about this group of fireflies, they flew in the air for a while, and then they would gather in one direction, and the more the fireflies gathered, the more they seemed to form a ball of light.

Guo Na was puzzled: "Why did they all gather together?" What's going on? ”

Shen Wei: "They seem to have their own consciousness, is there some conspiracy to get together?" ”

Yu Fan also stood up and carefully observed all this in front of him, now there are almost no fireflies in the city, and it is really rare to see this kind of scene.

Xinling has a bold assumption: "These guys are coming together, and they won't attack us, right?" How can it feel a little scary? Mommy. ”

Indeed, the fireflies gathered more and more, forming a pillar of light, and under this pillar of light, Yu Fan seemed more and more insignificant. In front of everyone's eyes, it seems that a glowing superstar monster has appeared out of thin air, which is creepy!

Chen Jieyang waved his hand and motioned for everyone to step back, after all, no one had ever seen such a strange thing.

But Yu Fan took advantage of everyone's inattention, and did the opposite, and Yu Fan quietly approached the firefly swarm.

When Chen Frameyang found Yu Fan, Yu Fan was already under the superstar pillar of light, and Chen Frameyang whispered on the spot: "Old Yu, what are you doing?" You are crazy? ”

Yu Fan didn't think so, squatted on the ground and carefully observed something, and then raised his head to look up at this pillar of light. The fireflies also seemed to sense Yu Fan's presence, the pillar of light spread out, and the fireflies surrounded Yu Fan, Yu Fan spread his arms, and seemed to be enjoying all this.

Everyone else has seen it, is Yu Fan crazy? Chen Jieyang rushed over without saying a word, drove away those fireflies, and pulled Yu Fan to run back.

Yu Fan was pulled by Chen Jiaoyang and said, "Old Chen, let go, what are you doing?" ”

Chen Jiaoyang: "What am I doing?" What are you doing? Don't want to die? ”

Yu Fan smiled: "It's the first time I've seen this kind of landscape, and I'm a little curious." ”

Chen Jieyang looked gloomy and said, "What if these fireflies attack you?" There are too many evil things in this place, you should be careful. ”

Yu Fan tidied up the collar that was torn crooked by Chen Xiangyang just now, and said calmly: "How can fireflies hurt humans? It's humans who have been harming fireflies all along. ”

Shen Wei: "I'm terrified of the kind of animals that can emit light. ”

Yu Fan smiled and said, "The reason why they glow is that a chemical called insect luciferase in the firefly's body interacts with oxygen to produce light. This chemical called insect luciferase initiates this reaction like a switch, and when the firefly produces insect luciferase, the reaction begins, and the firefly emits a flash of light. The luminescence of fireflies, in simple terms, is a series of complex biochemical reactions catalyzed by luciferin. There is no danger to humans. ”

Guo Na asked, "Then what is going on with these fireflies and why do they get together?" When I was a kid, I grew up in the countryside and had fireflies, but I never saw anything like that. ”

Yu Fan said a little mysteriously: "It's because they're also having a party." ”

Everyone seemed to be very surprised by Fan's answer, and they stared at Yu Fan with big eyes one by one.

Yu Fan didn't panic, sat cross-legged on the ground, and patiently explained to everyone: "They are just dining and falling in love." ”

Xinling asked curiously, "What do you say?" ”

Yu Fan: "Snails are the favorite food of firefly larvae. Once it rains, the ground is wet, and the rainwater pours into the shell to soak the mucus at the opening of the shell. will wake up the dormant snail. And the place where the fireflies gather is where the snails gather, and what I just observed confirmed this inference. Adult fireflies hardly eat or drink, they tend to eat only dew, honeydew or pollen, nectar, and they glow and gather for the purpose of courtship and mating. Because of the phototaxis characteristic, they naturally come together. ”

Chen Jieyang sighed: "Fireflies eat snails? The first time I heard about it. ”

Yu Fan: "In fact, fireflies do not directly eat snails, but inject a toxin into the snails, and then the snails will be paralyzed and become a puddle of liquid, so that the fireflies can slowly eat the snails, and in the end, only a snail shell remains." ”

Hearing Yu Fan say this, everyone's hanging hearts were much more relaxed.

Xinling sighed with emotion: "I've been to so many places, it's the first time I've seen such a spectacular firefly party, this time it's really right to follow you, this landscape is really breathtaking, incredible, incredible." ”

Yu Fan sighed and said: "In fact, this world was originally colorful, but with the development of human beings, people impose their so-called 'order' on the natural world, and the resources that can be used are used, and the resources that cannot be used are eliminated, but the natural world is a ring and a ring, interlocking. Humans pride themselves on exterminating pests that are not good for humans, but they also exterminate species that feed on pests. Over time, the ecological chain will become more and more homogeneous. ”

Chen Jianyang put forward his own point of view: "Since human beings can eliminate those pests by themselves, the original beneficial insects actually have no value in existence, and extinction will not affect anything." ”

Yu Fan said faintly: "Perhaps, in the eyes of the Creator, we humans are the biggest pests in the world. ”

It's not early, everyone is tired after a hard day. Each replied and rested in his tent.

Early tomorrow morning, we will continue to hurry.

Yu Fan was lying in the tent and brushing his mobile phone, the signal in this place was okay, indicating that there was a signal base station nearby, which meant that it was not particularly remote here, Yu Fan recorded what happened in the past few days, it was really a fulfilling day, there were surprises and regrets, the surprise was that he had personally experienced a lot of incredible things, unfortunately, some words were not able to say to Guo Na in the end. But these things are valuable experiences in his life. And experience is a person's greatest wealth.

In the tent, you can still faintly hear the laughter of Xinling and Shen Wei playing games, Yu Fan seems to have not felt such a happy and peaceful night for a long time.

I wish I could have frozen in time at this moment.
