In the early morning, when the first rays of sunlight shone through the swaying bamboo leaves on Xiao Yinling's beautiful little face, Bu Tian, Liu Rui, Feng Wu, and Duo'er had already come to the entrance of the 'Underground River'. Bu Tian pulled out a long bamboo raft from the hole, and there was a small shed in the middle of the raft that could provide shade from the sun and rain. Bu Tian pushed the bamboo raft hard along the current, and the bamboo raft slowly slid into the underground river...

Bu Tian jumped on the bamboo raft and said, "Come on, we're leaving." ”

Duo'er helped Liu Rui get on the bamboo raft first, and sat in the small shed in the middle, followed by Feng Wu and got on the bamboo raft. Bu Tian picked up the long bamboo pole and held it up like a captain, and the bamboo raft slowly moved along the wide underground river, and the light around it gradually dimmed.

"Do'er, light that lamp at the bow of the boat!" said Bu Tian.

Who would have thought that there would be such a natural underwater passage under this valley, and while sighing at the magic of nature, it is impossible not to mention the cleverness and insight of the little silver spirit.

Hidden in the mountains under the 'underground river' meandering, black do not know where to lead, although the river is not very wide, but not very narrow, it is estimated that like Bu Tian and Xiao Yinling made of this bamboo raft, side by side can put down two, the river is slightly blue, although the river light is dim, but you can also clearly see the blue and clear river bottom, the river water from time to time swim a few transparent small fish, there are a few around the bow of the light swirling, as if 'checking' something new.

The bamboo raft was under the control of Butian, the temporary captain, and it was getting farther and farther away from the entrance of the cave, and the surroundings gradually became extremely dark, except for the lamp on the bow of the boat to illuminate the way forward. The dark underground passage seems to stand still. The bamboo raft carried everyone along the river, and I don't know how long it took to go.

"It's so long here, it's like there's never going to be a point. Duo'er looked around and said.

"Don't worry, it's estimated that it will be at the exit in about half a day. Bu Tianyan said.

At this time, the river water suddenly changed color, the original blue water surface, now it gradually turned into dark green, the further the river color became, and more and more turbid, as if it was a pool of stagnant water, the original flowing water surface, at this time also still, calm and abnormal. Only the sound of bamboo rafts gliding by, waving the water.

"Look, what's that?" Doll said, pointing to the top of her head.

Everyone looked over their heads, and saw a group of small creatures with yellow shimmering lights flying above their heads, these small creatures grew about the size of bees, buzzing over the top of Butian's heads, and flew towards the other end of the river. Bu Tian didn't say a word, he pushed the bamboo pole hard, and slid the bamboo raft to chase after him.

Those little bee-like creatures seemed to know that Bu Tian was following behind, and suddenly flew in circles, deliberately slowing down, as if they were deliberately waiting for Bu Tian to catch up. At this time, the little creatures suddenly changed their form, put out a big arrow, and flew towards a fork in the river.

"Hey, how can there be a fork in the road here, Xiao Yinling didn't tell me. Bu Tian said darkly.

"Brother Tian, why don't you leave?" Feng Wu asked.

"Oh, it's okay, I just want to see which way we go. Bu Tian said.

At this time, those glowing little creatures saw that Butian and they did not follow, so they took the initiative to change their formation, and put out a big arrow, indicating the mouth of the river on the right, and flew slowly...

"Look, brother, those little things have turned into big glowing arrows, as if telling us which way to go. Duo'er said, pointing to the little creatures above her head. Bu Tian pondered for a while, carefully observed those glowing little creatures, and suddenly a flash of inspiration flashed in his head, as if he remembered what these glowing little things were, and couldn't help blurting out "Guiding fireflies!"

"What, Brother Tian, what did you just say... Worm!" Liu Rui said suspiciously.

Bu Tian smiled, and with a strong push on the bamboo pole, the bamboo raft turned crookedly, rowing towards the fork in the road on the right.

Bu Tian said while propping up the bamboo raft, "I know what these little things are, they are a kind of 'firefly' that has been extinct for a long time. Their name is 'Rock Bee Firefly'. It is a small creature with a spirit that generally lives in dark underground caverns and lives an isolated life. These little things especially like the breath of humans. Once there are people who have lost their way in caves, sinkholes and underground caves, as soon as they find it, this little thing will spontaneously come out and guide the lost people, and will always bring the human in distress to the surface. Once upon a time, humans called these creatures 'soul ferrymen', which means that they could bring souls lost in darkness out of the heavens. so that it can be reborn. ”

When Duo'er heard this, she was shocked and said, "Ah! Doesn't that mean that this little insect will directly bring us in... Did you go inside heaven? Then we won't be able to go home!"

Bu Tianbai glanced at Duo'er and said, "You want to be beautiful, is heaven so easy to enter, don't go through nine hundred and eighty-one difficulties, taste the ups and downs of life, how can it be so easy to go to heaven, it's the best if you don't go to hell, go to heaven! Don't think about it." ”

"Ah, I have to go through so many hardships of ninety-nine eighty-one, and the three disasters and two dilemmas are enough for me to bear, then I won't go to heaven, as long as I don't go to hell, I can go anywhere. Oh, by the way, I'll follow my brother, and I'll follow my brother wherever he goes. Doll said with a grin.

The bamboo raft followed those 'rock bee fireflies', along the narrow river channel, carefully sliding forward, the river channel somehow, became more and more narrow, almost only the width of the bamboo raft made of Butian, the water flow became more and more rapid, from time to time there were a few rocks exposed to the water, almost hit the small bamboo raft, the cloth angel did his best, left and right bows, firmly supported the bamboo raft, did not let it hit the rocks protruding from the water surface...

At this time, the 'rock bee fireflies' leading the way in front suddenly stopped, and put out a big exclamation mark very dramatically...

"Brother, look, those fireflies are gone, so they put on a big exclamation point. What does this mean, does it tell us that there is no road ahead? I'll just say, these little things are unreliable, what should I do now? Do'er said with a frown.

Bu Tian was also puzzled, "What the hell is going on, why did it suddenly stop, what do these little things want to tell me?" Just as Bu Tian was puzzled, a huge wave suddenly appeared on the water in front of him, and the waves surged towards Bu Tian...

"No, there's something in the water, everyone, hold on, don't fall into the water. Bu Tian said loudly.

As soon as the words fell, I saw a crimson 'big strange fish' appear on the water in front of me.

The five-meter-long, crimson 'Big Monster Fish' swam towards Butian and the others with its mouth the size of its head.

"'Earthfire Giant Catfish'! Grandma's leg, isn't this thing extinct for tens of millions of years, how could it appear here? Bu Tian said darkly.

······

The adult 'Earth Fire Catfish' is generally five or six meters long and more than two meters wide, with a huge mouth, hard upper and lower jawbones, which can bite rocks in one bite, and live in the 'Dinosaur Era' more than 60 million years ago.

The 'Earthfire Catfish' usually inhabits the underground karst caves and hot spring pools around extinct volcanoes, and lives on volcanic rocks and heat-tolerant organisms, rarely swimming out of the ground. Because of the high temperature of the water for a long time, the surface of its body gradually turns red, like a large red catfish. Because of its ferocity, there are very few natural enemies in the underground world, and I don't know what's going on, under the Qingcheng Mountain Range, this kind of creature suddenly appeared, and Bu Tian was a little stunned.

Bu Tian was a little puzzled and put his hand into the water to test the water temperature... It's cold, and the water here isn't hot, so how could this guy come from, and where did he come from? Bu Tian said to himself.

The three girls were so frightened that they didn't dare to come out, staring at Bu Tian motionlessly...

"Don't move, everyone, breathe slowly, don't alarm it, wait for it to swim past and it'll be fine, this big catfish generally doesn't like to eat people, if I remember correctly, this guy only likes to eat a hard stone." Bu Tian whispered.

The 'Earth Fire Giant Catfish' paddled the water, swam to the side of the bamboo raft, touched the bamboo raft with its huge mouth, shook its head violently, and went to the side...

"It doesn't seem to like the smell of bamboo. That's fine, so he'll be gone soon. Bu Tian said with a smile.

The 'Earth Fire Giant Catfish' bypassed the bamboo raft, swam to the side, and slowly left Butian and the others, thinking about the waters behind them, and the huge body made a splash of several meters from time to time, twisting its red body, like a big red monster looking for delicious food.

Bu Tian watched the 'Earth Fire Giant Catfish' slowly leave, and gradually breathed a sigh of relief, and was about to leave with the bamboo raft, when suddenly a baby's cry broke through the silent underground river passage...

"Wow... Wow..." Xiaobei sang happily.

The little north nose in Liu Rui's arms didn't know how to do it. Suddenly I woke up, and then I cried. Liu Rui hurriedly untied his clothes and gave Xiao Beibi a 'meal'! But the naughty Xiao Beibi didn't know what was going on, and just after a few bites, he stuck out his tongue and cried again as if he was sad, and the cry soon alarmed the 'Earth Fire Giant Catfish' who was about to leave. The Earthfire Catfish turned its massive body and sniffed into the air, then swam towards the Cloth Sky and them.

"Little rabbit cub, when is it not good to cry, but crying at this time, you kid sincerely make trouble for Lao Tzu. Don't cry, shut up! If you are crying, the big fish will be eaten by your mother, and who cares about you when you see it. Bu Tian said playfully at his son.

Liu Rui glanced at Bu Tian angrily and said, "What are you fooling around, can he understand what you say at such a young age." Let's hurry up and think of a way, didn't you see that big fish swimming back again, maybe it will come back to eat your son. ”

"Bah, what nonsense, it dares to eat my son, Lao Tzu will eat it first, you sit down, don't move, I will go down to meet this big fish, maybe we have fish to eat today." After Bu Tian finished speaking, he jumped up and jumped into the water, and swam up against the 'Earth Fire Giant Catfish'.

Thirty meters··· Twenty meters··· Ten meters··· Five meters, at a distance of five meters from the giant catfish, Bu Tian suddenly dived to the bottom of the water, pulled out the Qingling sword, and swam to the giant catfish from the bottom, Bu Tian quietly dived under the belly of the giant catfish, raised the Qingling sword in his hand, and aimed at the excretory hole of the giant catfish...

When it was about to be completed, the giant catfish suddenly flicked its tail and slapped it into the water, and the huge waves lifted out the cloth under the water. Bu Tian was knocked down in the air by the water waves, and fell freely towards the big mouth of the giant catfish...

Duo'er exclaimed, "Oh, my brother is going to be eaten by a big fish, and it's over." ”

Liu Rui said angrily, "Shut up, who said that your brother was going to be eaten by a big fish, didn't he stand there well." ”

Duo'er looked at it, and in the splash, she dimly saw Bu Tian standing on a rock behind the giant catfish, waving the small sword in his hand, and slashing the tail of the giant catfish.

The sword in his hand fell, and the sharp Qingling small sword cut off the half of the giant catfish's tail with one sword. The giant catfish shook its body in pain and made a baby-like cry. Bu Tian immediately understood, daring to love this is not an adult 'Earth Fire Giant Catfish', but a newly born small 'Earth Fire Giant Catfish'.

Bu Tian was confused again, according to the records in the ancient books, the juvenile 'Earth Fire Giant Catfish' was only one or two meters long, less than half a meter wide, and the size of the 'Earth Fire Giant Catfish' in front of him was obviously the size of an adult 'Earth Fire Giant Catfish'. What's going on here?

For a while, Bu Tian couldn't figure it out, the 'Earth Fire Giant Catfish' with half of its tail missing was fluttering up and down, and streams of black-red blood flowed into the water.

I don't know what's going on, the little north nose in Liu Rui's arms actually stopped crying after hearing the cry of the giant catfish, stared at the giant catfish, and giggled twice from time to time.

Bu Tian suddenly figured out one thing, the 'Earth Fire Giant Catfish' in front of him sounded obviously a juvenile 'Earth Fire Giant Catfish', which means that there must be one or even two adult 'Earth Fire Giant Catfish' nearby. There is no time to delay, take advantage of this small injury and leave this place quickly, or it will be a big trouble.

Bu Tian quickly jumped into the water, hurriedly swam to the bamboo raft, climbed on the bamboo raft and said, "You guys are holding on steadily, let's get out of here quickly, maybe there will be bigger monsters coming in a while, and if you don't run quickly, your life will be gone." ”

After speaking, he picked up the bamboo pole and propped it up to the bottom of the river, and the bamboo raft began to slide forward slowly... Xiao Wu, Duo'er, don't be idle, take two more bamboo poles and prop up the penny with me, so that we can get out of here faster. ”

When Feng Wu and Duo'er heard this, they hurriedly took two bamboo poles, one left and one right, to help Bu Tian support the penny, and the little bamboo raft was suddenly fast. Continue sliding towards the other side of the river.

Bu Tian looked up at the 'Rock Bee Fireflies', and saw that the small 'Rock Bee Fireflies' flew forward in a glowing arrow.

Bu Tian made great efforts to support the penny, followed those 'rock bee fireflies' like the front row, seeing that it was getting farther and farther away from the juvenile 'earth fire giant catfish', it seemed that he couldn't hear the cry of the giant catfish, Bu Tian couldn't help but breathe a sigh of relief, and was about to rest for a while, when suddenly, there was a 'coo... Cooing. Bu Tian was startled and shouted... Not good!
