Chapter 782: . Firefly Cave (3/5)

Potter turned back and saw that the employee who was monitoring the camera car in front of the screen was exclaiming, and he was so nervous that he cried, "What happened? What did you see?"
"I'm not sure, boss, come and see, I think, I think we've found something incredible!" The man cried excitedly.
Potter and his engineers hurried to the past. The 21-inch high-definition computer screen was dark green as a whole, with countless white light spots flashing on it, and four or five things like white training in front of it. It seems like a dense night sky.
Because of technical bottlenecks, this civilian camera car sees a scene similar to a night vision device before turning on the lights. The background color is dark green, there are no colorful colors, and the others are white and black.
The specific situation of the underground cave is not visible on the screen, but these are all engineering experts present, and they still have some guesses:
"Is the flickering mica stone? It looks beautiful."
"No, there is no light source, how can mica stones emit light? Even if there is a light source, they need to change the intensity of the light to flicker, I guess ..."
"This is a firefly hole!" The white chief engineer was very knowledgeable after all. "I went to the Te Anau firefly hole to assist in exploration. At the time, it looked like this from the camera!"
After hearing this, Potter took a sigh of relief, and said, "My God, wouldn't we be so lucky, would we encounter a firefly hole here?"
Firefly caves, as the name suggests, are stone caves where firefly colonies gather. Generally there are underground caves, because this environment is more humid and warm, which is suitable for firefly reproduction and survival.
This cave is relatively rare in the world and is one of New Zealand's tourism trump cards, but firefly holes are not particularly common in this country.
Porter continued: "I've seen it when I went to Lake Taupo on the North Island. It's a dream place!"
Lake Taupo is the largest lake in New Zealand, covering an area of ​​650 square kilometers. The surrounding terrain is complex and the species are diverse.
However, the firefly cave in Te Anau is more famous. It was developed early. The natural conditions of the cave are peculiar. The tour arrangements and facilities are also more perfect.
It is not difficult to determine whether this is a firefly hole. The camera car has a light source. The reason why it was not previously opened is to worry about disturbing some of the dangerous factors that may exist in the hole.
An engineer said anxiously, "What are you waiting for? Turn on the lights of the probe car, let's see what's below!"
Potter waved his hand and refused. "This is a place where personalities have never been involved. Do n’t turn on the lights. Who knows what the unknown impact will be? There are also some chain reactions, and we can't guarantee it."
"How do you determine the identity of the cave below?"
"Of course you need to turn on the lights, but that's not what we say. Call the mayor Wang and let him decide." Potter said.
He is the most responsible approach, and there are special rules for visiting the firefly cave:
Stalactites and stalagmites will lose their color and damage their fragile structure due to touch. They must be cherished and never touched by hand; they must be kept quiet in the firefly caves, and they cannot scare and destroy the ecological environment of fireflies.
There is also a total ban on smoking and the use of cameras and video recorders is prohibited during the entire process. Sudden light sources will affect the vitality of these insects.
After receiving the phone call, Wang Bo rushed to him. He also got to know the firefly hole in New Zealand.
Strictly speaking, this cave should not be called a firefly hole. The glowing insects in the cave are not fireflies, but a kind of glowing mushroom fly.
Fireflies are collectively referred to as Coleoptera, a family of fireflies of the order Coleoptera. There are about 2,000 species in the world, distributed in tropical, subtropical, and temperate parts of the world. There are more than fifty species in New Zealand.
A species of the genus Diptera, Diptera, Cryptocera, which is slightly larger than fireflies. But they like to live in the dark and dark caves, and they emit light like fireflies, making the dark cave tops like the starry night sky.
Therefore, the place where luminous mushroom flies exist is often developed into a tourism project as a novel natural landscape.
The reason why it is called a firefly hole is that it is easy for visitors to understand, and the second is to add a romantic imagination to the tour.
After all, everyone knows what a firefly is, the mushroom fly is not good, and the mushroom fly is beautiful, but the word 'fly' in the name is not good, and it is easy to associate with the fly. For the sake of tourism, no one uses it. To name the cave.
What's more, foreigners, especially Europeans and Americans, have a strong firefly plot. When the night is quiet and the breeze is studying, the starry sky above the head, where the firefly swarms dance, is considered by them to be the most romantic.
Wang Bo is not sure if he is a firefly hole here, because the lord ’s heart is not distracted to manage the location of the cave. He cannot see the inside from the sand table, and he does not even know that there are caves on his site.
Driving to a place two kilometers southeast of the lakeside beach, Potter and others were waiting for him. After he got out of the car, Potter asked directly, "Would you like to turn on the lights?"
Even if the cave is turned on, it will not cause large-scale death of mushroom flies, but it is uncertain, and Porter is more responsible, so he first notified him and let him, the master, make a decision.
Wang Bo thought about it and asked, "If you don't turn on the lights, you can't determine the identity of the cave below."
The chief engineer said, "No, there is another way, that is, if the person goes down in person, the human eye can determine whether this is a firefly hole or not.
Wang Bo asked: "What is the criterion?"
When he asked that, he was giving an answer. Porter held him back and said, "Hey brother, are you crazy? As hard as that? This is too risky!"
Wang Bo laughed: "Don't worry, what could be the danger? The most dangerous creature I encountered in New Zealand was the bee. Okay, tell me, what is the criterion?"
The chief engineer said: "There is no judgement criterion. When you see it, if it is a firefly hole, your brain will tell you that this is a firefly hole."
This answer is the same as no answer, Pharaoh laughed: "Are you doing philosophy?"
Potter replied on behalf of the chief engineer: "It's true, Wang, if it is a firefly hole, you will understand when you see it, it is a firefly hole!"
Wang Bo said, "Well, let's go and see. Who wants to go with me?"
"Without a light source? This is crazy! Mushroom flies like to live in a place where there is no light. Except that they emit light by themselves, you can't see anything!" Someone cried in surprise. (To be continued.)
