After kicking Bai Tuanzi into the cave, Ji Cheng also bent down and went in. The cave is not too high, it is estimated to be only half a meter, and the sprouts and edamame still need to keep their heads down, not to mention the rest of the adults.

Ji Ying snapped his fingers, and a churning spiritual flame danced in mid-air, illuminating the mountain tunnel, but he saw Bai Tuanzi not far away rushing over, pointing at the flame, and squeaking in his mouth.

"What's it called?" Bu Ting was the last to enter, and as soon as he entered the passage, his brain was hurt by the sound of rats echoing in the tunnel, and he even felt that several snakes on his body were all yelling and ready to move.

"Is there some phototropic animal in the cave?" Ji Yin extinguished the aura, and the people who had finally adapted to the light fell back into the dark world.

But fortunately, the people here are not ordinary people. The spiritual power is attached to the eyes, and he will soon be able to see at night. Even the bean sprouts edamame that can't be used were caressed by Ji Ying's eyes.

Bai Tuanzi breathed a sigh of relief: if the broken thing in there was provoked, then there would only be a chance to escape.

The half-meter-high cave is very unfriendly to their group of tall people, but it is estimated that this section is only about ten meters, and everyone is too lazy to toss and move forward with both hands and feet.

It seems that a threshold has been crossed, and the space in front of it suddenly becomes larger. Ji Cheng straightened up and stretched his waist, his bones making a crisp sound. He patted his knee again before he began to look around.

Rainwater seeps down the cracks of the limestone rock layers, and the slightly acidic carbon dioxide in the air erodes the ground day by day, causing the rock crevices to gradually expand, and the stalactites on the top of the cave are dense, and the stalagmites at the bottom of the cave are numerous.

Dark water flowed at the bottom of the cave, rushing madly through the cave, and suddenly turning in the center and running towards the hole in the wall on the other side, as if from there a step had been lowered into the lake.

Due to the alluvial accumulation of hard black stones, the smooth black stones like balls are stranded on both sides of the river, like briquettes in cartoons, which are very cute.

"This should be a very young living hole, maybe it has only formed ten thousand years?"

The flowers of the court made the eyes of a group of little ones widen. Although the oldest Ji Cheng and Bu Tinghu Yu here are only a few thousand years old, this cave is indeed the youngest in the cave.

The underground river is rushing endlessly, and although the movement is large, the spiritual power contained in the lake water is very small, like stagnant water.

Bai Tuanzi ran directly in the direction of the underground river on the opposite side, deep and shallow. The diameter of the cave gradually shrank in that direction, and the diameter of the cave was still more than three meters.

The sound of water accompanies everyone on their way. I didn't go far before I noticed that there seemed to be light and shadow fluctuations on the water surface in front of me.

A greenish-white shimmer appeared on the rocks, like a sky full of stars, twinkling and shining. In the dim light, countless translucent filaments of varying lengths poured down from the roof of the cave. There are many "water droplets" on each filament, which is very much like a crystal bead curtain, and the blue fluorescence and turquoise form a visual conflict.

It was a beautiful sight, like a sky full of stars.

Bean sprouts and edamame once saw a tree of fireflies on the shore of Dongting Lake, and the shocking scenery at that time was nothing compared to the scenery in front of them.

"Is this a bug?" The long and short silk threads hung on the top of her head, and the longer ones seemed to be close to a meter long, and Huang Ying felt that she could reach them with her hand.

But before she could raise her hand, she was grabbed by Feng Yi, "Don't touch it, those are insects." ”

"Today there is a worm, as big as a grain of rice, stinging in winter and summer, rising in the day and night, and shining in all directions." Ji Cheng looked up at the starlight above, "This should be a firefly larva." The eggs glow green, and the larvae turn blue. In caves, the larvae secrete filaments with slime like droplets, and the insects in the cave follow the light and cannot move when they hit the filament. The larvae then crawl down the filaments and swallow the prey into their stomachs. ”

These fireflies need plenty of humidity to avoid drying up and dying, a proper environment for the spitting threads to hang stably, and a dark space to emit a glimmer of light, and this cave is an ideal living space that is natural and perfectly coordinated.

This also means that there must be other entrances to the cave, otherwise no insects will come in and become food; In addition, the black river water may be non-toxic and harmless, after all, common fireflies have extremely high requirements for water sources.

Of course, it is also possible that this population has adapted to the environment.

The voices of several people were not loud, but Bai Tuanzi did rub well, and his little paws gestured in front of his mouth to silence him.

"Can't speak?" Huang Ying asked in a whisper, but it was too late.

Suddenly, there was a dense sound of the hard shell breaking from the top of the cave, and everyone felt numb in their spine. More than half of the original fluorescent green has turned into ice blue. The adults bite through the cocoons that cover them, revealing a pair of slender antennae. Then the sharp teeth began to gnaw at the pupa, like a churner.

After swallowing it all, they tentatively spread their thin, transparent wings. The fluttering wings of many adults form waves under the blue light of the luminaire on their tails.

A sense of crisis rose from the depths of his heart, and Ji Ying raised his hand and used his spiritual power to prop up the round cover and envelop everyone.

The first fireflies had already flapped their wings away from the rock wall, swooping down with mouths half the size of their heads, their small hemispherical eyes reflecting the blue light of the sky.

The dense insects hit the spiritual power shield, and the movement made people's scalps tingle. After a few waves, the bugs seemed to realize the impossibility of brute force, and one by one they covered the sphere to the brim, their sharp teeth illuminated by the cold light and began to gnaw at the aura shield.

"What kind of broken breed is this?" Ji Ying frowned and looked at Buting, but the other party just spread his hands and shook his head.

There are thousands of varieties of fireflies, and there are nearly 2,000 in the human world alone, not to mention the species that eat metals and ores in the mountains and seas.

But most adult fireflies that grow in the dark don't have mouths. After hatching, their only action is to reproduce, and then the adults who have run out of oil will crash into the filaments secreted by the larvae to provide nutrients for the larvae to grow.

Not to mention that this kind of Ji Yin, who can directly gnaw spiritual power with a mouthful of sharp teeth, is unheard of.

The surface of the spiritual power shield soon began to be uneven, but this kind of shallow pit, Ji Ying filled them with a look.

The endless spiritual power seemed to make the fireflies more and more excited. The wings shook wildly, and there was a "buzzing" roar. In response, everyone heard the sound of wings fluttering from the depths of the cave. TVmobile/

Everyone's faces suddenly became even more embarrassed: is this a rhythm that never stops?

Ji Cheng was the one with the worst face, and instead of muttering about those insects in his heart, he greeted a group of old immortals: If it weren't for this group of villains, would I be guilty of coming to such a place?

Not a single good thing has happened since the ship was sunk by the beast of the deep.
