Ladybugs fly freely in the hole.

With the faint light emitted by these ladybugs, they could barely make out the outline and direction of the cave.

I finally see a glimmer of light!

Both were overjoyed.

The further I went, the clearer the sound of the rushing water became, and there were more of those unknown fluorescent drifting insects, looking up like the sky was full of stars!

Feng'er was even more excited, she raised her hands high, these stars seemed to be close at hand!

She picked up a stone and threw it deep into the cave, only to hear a "bang", the echo echoed far away in the cave, and the fluorescent light suddenly brightened with the sound waves, and then dimmed again.

Nangong Xun suddenly felt strange, and also threw out a stone, the stone hit the stone wall in the distance and rolled down, the faint fluorescence suddenly brightened, and the sound became dim after a while.

Could it be that the strength of the light of these drifting insects is related to the magnitude of the external sound?

Feng'er giggled for a while and said, "Brother Xun, when did you start and be so good at playing?"

Nangong looked at her and smiled without saying a word, but continued to knock lightly on the stone wall.

"Boom!"

"Boom!"

......

A rhythmic sound of percussion was heard far along the cave.

After a while, ladybugs gathered from afar one after another, and the light became brighter and brighter!

One, two, three...

After a while, it was like a sky full of stars, and the starry light was spectacular.

Feng'er waved her arms and yelled at them, urging Nangong Xun: "Brother Xun, hurry up!"

Nangong Xun was also happy in his heart, and said in his heart: "As long as I keep knocking on the stone wall while walking, these fireflies will linger around the left and right, and they will be colorful along the way, which can be regarded as living up to the original desire to pick stars for Feng'er!"

Feng'er danced excitedly, raising her hands and embracing them with open arms to greet these light messengers in the darkness!

"Oops! it hurts!" Feng'er suddenly exclaimed.

There was a burning sting in her arm!

The aching skin had blistered and began to fester......

With the faint light, Nangong Xun was surprised to find that these flying glowing ladybugs in the cave looked a bit like dragonflies.

They have a pair of transparent tulle-like wings that are so flexible that they can be placed in the air as if they don't understand, or they can be lost without a trace.

In addition to their heads, their bodies are like a translucent light sac that glows, and they even have a mosquito-like needle-like mouthpart, which does not bite people, but secretes a sticky mass.

It's this sticky stuff that makes the wound so painful!

This is definitely something that the two of them never expected!

Seeing a large group of ladybugs swarming in the distance, Feng'er's face suddenly turned pale.

What a terrible thing it would be to get around these horrible little things!

Nangong Xun didn't have time to think about it, so he pulled Feng'er and rolled over and rolled into the dark river on his side.

The river was not too deep but it was cold to the bone, and the squatting body was just enough to expose a head, and the two of them could only grit their teeth and endure it.

Listening to the buzzing in their ears, a large circle of light lingering on the surface of the water, these ladybugs seemed to be afraid of water, clinging to the surface of the water but did not dare to sink for half a minute.

Shicai appreciated the power of these inconspicuous little things, and the two of them didn't dare to be careless at the moment, and dived their heads into half a minute, leaving only two nostrils to breathe.

These unknown ladybugs seem to refuse to give up, gathering less than a foot above the surface of the water and refusing to leave.

Feng'er was so frightened that she couldn't say a word, Nangong Xun was also shocked, and said secretly: "We can't go on like this! If we are so stalemate for a few more hours, don't say that we will escape, I am afraid that I will freeze to death in this glacier!"
