"Ahh Woo-"

Unprepared, I plunged into the underground river, fluttered a few times in a panic, and drank several sips of water.

"Xiao Gu! What's wrong?! ”

I vaguely heard the voice of the seventh master, but this underground river looks very calm on the bank, in fact, there are countless undercurrents below, my body turned around in the river several times, and I couldn't control it at all for a while, and I kept pouring water.

"Xiao Gu, grab the rope!"

With the shout of the seventh master, I heard a muffled sound of "pop" around me, as if a rope was thrown beside me, and hurriedly reached out and groped, and soon grabbed it, and the seventh master pulled on the shore, and then stabilized his body, spit out the water in his mouth, and swam to the shore.

"That's not right!" After swimming twice, I suddenly remembered the black shadow I had just seen, and shouted to the Seventh Master: "Seventh Master, look at what is in the river around me?!" ”

The seventh master answered, and took a flashlight to shine around me, and I also took a flashlight to shine around, but found that the thing was gone!

"Xiao Gu, come up first!" The Seventh Master shouted.

I nodded, pulled the rope and swam over, and went ashore, I was already a soup chicken, and my head was still a little buzzing, it should be the loud "moo" I heard before, and I haven't eased my mind yet.

"Not enough for you to toss!" Liang Ruoyi seemed to be awakened from my sleep and stood aside, with a look of anger on her pretty face.

"Hey!" I smirked while patting the water on my face: "I don't want to toss either...... By the way, Seventh Master, did you hear this voice just now? ”

"The cow's cry?" The Seventh Master asked rhetorically.

I was stunned for a moment, only to realize that the sound was seven or eight points similar to the cow's bark, I always thought it was a pig's head, is it a monster?

"It seems, it's really like a cow!" I scratched my head embarrassedly: "When I woke up before, I heard the sound of running water here was much quieter, so I wanted to come and see, halfway through, I suddenly heard a snoring sound, I thought it was a pig's head coming, and I thought about whether he was injured and fainted, so I hurriedly ran over, after coming, I took a flashlight in the river to look for it, and then I saw a black figure in the position just now, I thought about waking up the pig's head, but I didn't expect to just move twice, and I heard that' The moo sound was deafening, and it made my head dizzy, and I didn't react at all, and plunged headlong into the river......"

"You're stupid, you're still asleep!" Liang Ruoyi's angry Northeast words burst out: "You can't tell the difference between a person and a cow?!" However, how can there be cows in this place? I've never heard of manatees making the sounds of cattlemen on land......"

"You're stupid!" I laughed and said, "The ones on land are called freshwater buffaloes, and the ones in the sea are called saltwater buffaloes, and they can all ......."

"Smack!"

"Ahh

"Get out! Your saltwater buffalo?! Liang Ruoyi didn't wait for me to finish speaking, slapped me on the head, and scolded when he opened his mouth.

I shrugged my shoulders and clutched my head to the campfire, thinking about drying my wet clothes first. The Seventh Master and the Budai monk on the side didn't care about the two of us, and observed along the shore for a while, but didn't find anything abnormal.

"This place is really weird." The two walked back, and the seventh master said with a wry smile: "It stands to reason that such a small hole has not been washed away for so many years, and this place has not been flooded, it is already beyond ordinary scientific principles, and now it is found that the flow rate of this underground river pouring in from the outside can also change, you must know that this whole mountain is buried in the sea!" It's unpredictable......"

"Could it be, Undercurrent?" Liang Ruoyi frowned slightly, and was sitting on the side preparing breakfast for everyone: "A few years ago, during an operation in the Indian Ocean, I encountered a very strange undercurrent in the sea. It is two undercurrents that travel opposite each other, and after colliding, they will turn in the same direction, thus carrying away a part of the sea water behind them, so as to form a spectacle - the two undercurrents are moving forward at a rapid speed, while the sea water behind them will be in a relatively static state for a certain period of time, which looks like an astronomical spectacle. ”

"This ......" the seventh master nodded: "It's possible, but I'm not an expert in this area, the situation you said requires too many conditions, whether it is temperature or pressure, it must be exactly at an appropriate value to form this kind of scene." This underground river...... It's kind of weird, too. ”

Liang Ruoyi didn't say anything more, and distributed food to everyone, and everyone looked around while eating.

There were no pig's heads here, and the four of us seemed to have eaten too little......

"Seventh Master, what is that voice just now?" I still can't help but ask.

"Do you see that thing clearly?" The Seventh Master asked rhetorically.

"Nope." I smiled bitterly and shook my head: "It was so dark before, I just took a flashlight to shine it, and the thing was still in the water, mainly because I heard the snoring, I thought it was a pig's head, and when I took a step back, I didn't think it would be a person." I didn't expect it to be ...... That scream startled me! ”

"What color do you look at it?" The Seventh Master asked again.

I took a bite of a large piece of ham and thought as I chewed it, "It looks a little greenish, but could it be because it's in the water?" ”

"Green?" The Seventh Master frowned, and turned his head to look at the Budai monk: "Master, if it is according to what Xiao Gu said, that thing just now, could it be a cow fish?" ”

The cloth bag monk ate the bread with an expressionless face, raised his eyes to look at the seventh master, and nodded: "Yes." ”

Depend on! This old monk, I guess he already knew what that thing was, and he sat here without saying a word, looking like he didn't care about himself and hung up high.

"What is a cowfish?" When I heard that there was something new to know, I couldn't wait to ask, "Is it a fish or a cow?" ”

"This is a fish that looks like a cow...... the seventh master said and shook his head again: "It's not right, it should be said that it is an amphibian that looks like a cow." This thing has been recorded in the "Naturalist Chronicles", and in some places it is a legendary water ghost, and few people have seen it, and I don't know if it really exists or is made up. But if there is such a thing in this place......"

The seventh master paused when he said this, and the cloth bag monk on the side said: "This thing likes water, and can predict the ebb and flow of the tide, likes to eat small fish and shrimp, and the microbiota in the sea, so it usually likes to live in the sea or by the sea with many undercurrents, high tides and low tides." When the fur is opened, the tide rises to the undercurrent; When the fur lies flat, the tide flows down. ”

"The master is right." The seventh master nodded: "In this way, Miss Liang's undercurrent theory can be confirmed." ”

"This thing, I guess we happened to come across it......" I smiled wryly, "but it scared me a lot." ”

The seventh master smiled: "Not necessarily, I haven't seen this thing anyway, and I haven't heard that others have seen it, this thing is very timid, once it is alarmed, it will let out the kind of scream just now, I think, if it comes a few more times, this cave will be collapsed by it!" ”

After chatting for a while, and after breakfast, it was already more than nine o'clock in the morning, and we packed up our things and walked towards the front.

The flow rate of the underground river is still very slow, according to the previous Budai monk, there should have just been two undercurrents colliding outside the cave entrance, and then took away a part of the sea water to the opposite side of the cave entrance, thus slowing down the flow of the underground river. Although this explanation does not seem to be supported by many scientific principles, it is the most plausible explanation we can think of.

We walked along the underground river for about half an hour, and there was still no change in the surroundings, except for the stones.

"It's not going to work like this." The Seventh Master stopped and said: "I can't discern the direction now, this river, I always feel that there is a problem with the flow direction, let's find the mountain wall on one side and walk along the mountain wall." ”

Everyone looked at each other, had no objection, turned around and followed the seventh master towards the left, and at about half past ten, we finally saw the mountain wall on the left! When we took a flashlight and saw the mountain wall clearly in the dark, we made an unexpected discovery......
