Porter turned around and saw the employee who was surveillance camera car in front of the screen who was screaming. He suddenly felt nervous and shouted, "What's wrong? What did you see?"

"I'm not sure, boss, come and take a look. I think, I think we have discovered something amazing!" the man shouted excitedly.

Porter and his engineers hurriedly walked over. The 21-inch high-definition computer screen was dark green overall, with countless flashing white spots on it. There were four or five things that seemed like white craftsmanship in front of it. The light and shadow on it flashed, as if it was a dense night sky.

Due to technical bottlenecks, what this kind of civilian camera car sees a scene similar to a night vision device before turning on the lights. The background color is dark green, and there are no colorful colors, and the others are white and black.

The specific situation of the underground cave cannot be seen from the screen, but these are engineering experts present, and they still have some guesses:

"Does the flashing mica stone? It looks pretty."

"No, without the existence of a light source, how can mica stone shine? Even if there is a light source, they need to flash and change the intensity of the light, I guess..."

"This is a firefly cave!" The white chief engineer was very knowledgeable after all. "I went to the Te Anau Firefly Cave to assist in exploration. At that time, from the camera car, this was what it looked like!"

After hearing this, Potter took a breath and said, "My God, we won't be so lucky, are we going to encounter a firefly hole here?"

As the name suggests, the firefly cave is a stone cave where fireflies gather. It usually has underground caves because such an environment is humid and warmer, suitable for fireflies to reproduce and survive.

This kind of cave is relatively rare in the world and is one of New Zealand's tourism aces, but in this country, firefly caves are not particularly common.

Porter continued: "I saw it when I went to Lake Taupo on North Island, it was a dream place!"

Lake Taupo is New Zealand's largest lake with an area of ​​650 square kilometers, with a complex terrain and a variety of species.

However, Te Anau's firefly cave is more famous. It was developed early, the natural conditions of the cave are unique, and the tour arrangements and facilities are also more complete. The entrance of Te Anau's firefly cave is on the lake surface. You must transfer to a small flatbed to enter the cave.

It is not difficult to judge whether this is a firefly cave. The camera car has a light source. The reason why it was not opened before was because it was worried that some of the possible risk factors that might be disturbed in the cave.

An engineer said anxiously: "What are you waiting for? Turn on the lights of the detection vehicle and let's see what's underneath!"

Porter waved his hand and refused, saying, "This is a place that humans have not been involved in. Don't turn on the lights. Who knows what unknown impact will bring? There are also some chain reactions that we can't guarantee."

"How do you determine the identity of the cave below?"

"Of course, the lights need to be turned on, but that's not our final say. Call Mayor Wang and let him come over and decide." Potter said.

This is the most responsible approach, and there are several special regulations for visiting firefly caves:

Stalactites and stalagmites will lose their color due to touch and destroy their fragile composition. They must be cherished and never touched with their hands. They must be kept quiet in the cave of fireflies and cannot be scared and destroyed by the ecological environment of fireflies.

There is also a complete ban on smoking, and the use of cameras and video recorders is prohibited throughout the process. The sudden appearance of light sources will affect the vitality of these insects.

Wang Bo rushed over after receiving the call. On the way, he also learned about the firefly cave in New Zealand.

Strictly speaking, this kind of cave should not be called a firefly cave. The glowing insects in the cave are not fireflies, but a kind of glowing mushroom fly.

Fireflies are a general term for the Coryptozoae insects. There are about 2,000 species in the world, distributed in some areas of the tropical, subtropical and temperate zones. There are about 50 species in New Zealand.

The luminous fungus is a type of the family Dipterae, and is slightly larger than the fireflies. However, they like to live in dark and dark caves, and will emit light like fireflies, making the dark cave roofs look like stars in the night sky.

Therefore, where glowing mushroom flies exist, they are often developed into tourism projects as a novel natural landscape.

The reason why it is called a firefly cave is that it is easy for tourists to understand, and the other is that it adds a romantic imagination to the tour.

After all, everyone knows what fireflies are, but mushroom flies are not good. Moreover, mushroom flies are very beautiful, but the word "flies" in the name is not nice and easily reminds people of flies. For the sake of tourism, no one uses its real name to name the cave.

Also, foreigners, especially Europeans and Americans, have strong fireflies plots. When the night is late and the breeze is blowing, the galaxy is bright above their heads, and they are in a place where fireflies dance gracefully, which is considered the most romantic.

Wang Bo was not sure if he was a firefly cave, because the Lord's Heart was not distracted from managing the location of the cave. He could not see the scene inside from the sand table, and he didn't even know that there was a cave on his territory.

He drove to a place two kilometers southeast of the lakeside beach. Porter and others were waiting for him. After he got off the car, Porter asked directly: "Do you want to turn on the lights and make sure?"

Even if the lights are turned on in the cave, it will not cause large-scale deaths of mushroom flies. It is just that it is uncertain. Porter is more responsible, so he notified him first and asked him, the master, to make the decision.

Wang Bo considered it for a while and asked, "If you don't turn on the lights, you will definitely not be able to determine the identity of the cave below?"

The chief engineer said: "No, there is another way, that is, people go down in person, and the human eye can determine this. Whether it is a firefly hole can be determined at a glance."

Wang Bo asked: "What is the criterion for judgment?"

His question was equivalent to giving an answer. Porter grabbed him and said, "Hey brother, are you crazy? As for how desperate it is? This is too risky!"

Wang Bo smiled and said, "Don't worry, what dangers can be? The most dangerous creature I encountered in New Zealand is the bees. OK, tell me, what is the criterion for judgment?"

The chief engineer said: "There is no criterion for judgment. When you see it, if it is a firefly hole, your brain will tell you that this is a firefly hole."

This answer is like no answer, and Lao Wang laughed: "Are you doing philosophy?"

Porter answered for the chief engineer: "It's true, Wang, if it was a firefly hole, you will understand when you see it, it's a firefly hole!"

Wang Bo said, "Okay, I'll go down and take a look. Who would like to go together?"

"No light source? This is crazy! Muslims like to live in places without light. Except for them, they shine themselves, and you can't see anything!" Someone shouted in surprise. (To be continued.)
