"Xiao Haozi is right, take a closer look, maybe there is another way?" Brother arrogant said. Pen "Fun" Pavilion www.biquge.info

At this time, Li Feiyu seemed to have discovered something, and said: "No need to look for it, it looks like the mechanism has been opened, you see, under this river, although the undercurrent is surging, but if you take a closer look, you will find that I look at the hidden bridge in this river!" ”

"Huh! It seems to be true, alas, it shouldn't look deeper, I don't think it can reach the knee position! I didn't pay attention to it just now, but I only saw that the river was surging and it looked deep! Now it seems that it should be a dark bridge that has risen and blocked the flow of water, so that this seemingly very dangerous scene has been formed! ”

Li Feiyu probed with his foot! Then I saw him standing directly in the middle of the river.

"You wait here for a while, I'll go first, if there is no danger, you are coming!" Li Feiyu said.

We had to nod, and it was right to think about it, if there was really any danger, with Li Feiyu's skills, it shouldn't be a problem to retreat.

After a long time, Li Feiyu crossed the river straight and found that this danger was just a kind of fear on the surface, and there was no danger when he really found the hidden bridge in the river.

Li Feiyu waved on the other side of the river, signaling that we could go over, and we were immediately overjoyed, and then began to step into the river!

It turned out that in the middle of the river, there were huge pillars, connected together. Something resembles a bridge.

Soon after, when we crossed the river, we were all secretly relieved.

Call!

"This mechanism is really cleverly designed, if it weren't for Feiyu's careful observation just now, we would really have to swim over! Ha ha! The cousin said with a smile.

"Don't talk about this yet, I don't know what danger lies ahead! The bloody corpse just now shows that something may have happened to the third uncle! I worried.

"In that case, then what are you waiting for!" Brother arrogant said.

But. His voice just fell! The mutation has appeared!

I saw that the river we had crossed just now was beginning to rise violently! The waves are choppy!

Thundered!

The water is rising fiercely! I cursed! "Damn! What to do now! ”

"Run in the direction of the dungeon! It should be tide time! "I guess it's going to be high tide," anxiously said.

The tide behind us is like a water dragon, rushing towards us!

I glanced back and thought, "If I get pounced, I'm going to choke on it!" ”

Whew!

We're fast! Like a sharp arrow, run quickly to the dungeon!

The tide behind was in hot pursuit, but when the tide was about to approach the dungeon, it stopped! Form a wall of water and envelop the entire dungeon inside!

"I'll go! What is this and the situation? How stopped! "Brother arrogant doesn't know why.

"Could it be that this underground palace has a formation to block the invasion of this tide? Look! Around the dungeon, there was actually a layer of light blue ghostly light flickering! I exclaimed.

"Is it really a formation? Is there really a prehistoric civilization in this? If it's true, it's amazing! Li Feiyu's heart is not calm at the moment!

I looked up at the sky, only to find that above this underground palace, a starry sky was actually conjured up at this moment! There are stars around, but the most obvious is the full moon in the sky!

I was amazed, "Damn, this is the first time I've seen such a beautiful moon in the dungeon." ”

"Something is wrong, how can you see the moon in this underground palace? It's not scientific! My cousin wondered, I really don't understand!

"Huh? That's right! It was still pitch black just now, why did such a full moon suddenly appear? Li Feiyu said strangely.

I was shocked in my heart, just now I only cared about appreciating the beauty of the moonlight, but I forgot about this aspect of the problem! Could it be?

My actions attracted the attention of others, "Wu Hao, did you think of something?" ”

I looked at the moon and said, "If what I just guessed is correct, there should be something related to why this tide pool is high and why the river outside this underground palace is also high tide, and this common connection point should be it!" ”

With that, I pointed to the full moon in the sky.

"It? Moon? What's the connection? Eighteen million kilometers away! The cousin wondered.

I said, "I don't know if you've forgotten what you've learned!" Gravitation! If I'm not mistaken! This high tide has to do with gravity! ”

Then I began to explain to the others, "The gravitational pull of the moon and the earth can be said to be very large!" And the moon revolves around the earth, so the distance between the moon and our location is sometimes longer, sometimes shorter! This makes a difference in gravity! And the high tide away is the same, at the high tide, the gravitational force is larger, the river water from other places to attract the trend, the formation of the tide trend, on the contrary, everyone should understand! ”

The cousin scratched his head and said, "Brother Hao, we didn't understand what you said very well, so you just say, what's the point of this underground palace cultivation here!" ”

"I think this should be a self-protection measure! You see, at high tide, this underground palace is surrounded by rivers on all sides, enveloping the entire underground palace, and the outside world cannot see where this underground palace is. I can barely explain it with this reason, and of course the real reason is known only to the people of the world.

"Don't worry about it so much, since the tide can't rise in this dungeon and is blocked by this inexplicable formation, then we should go to the third master and them as soon as possible." Li Feiyu said.

"Yes, I have a headache after thinking about it so much, I don't want to, let's see what good things are in this dungeon!!" Arrogant brother said.

"Everyone should be careful, it doesn't look so calm here, there should be a reason for the bloody corpse, everyone pay attention to the surrounding situation!" I reminded.

After everyone found that it was okay, they began to look at the underground palace in front of them.

I saw all kinds of strange-shaped buildings in the entire underground palace.

We have never seen such a building in reality.

Some of the buildings are made of unknown bones, and there is something like coral growing on the outside!

And some actually use unknown metal to build luxury buildings.

"What's going on? Could it be that we have really come to a prehistoric civilization? You see, these things, I don't think even with today's technology can achieve them! "Brother arrogant is relatively proficient in modern architecture, and now he is actually taken aback by the scene in front of him.

"I think we may have come to the future! This thing, if we say it is an alien civilization, others will believe it, and if it is said to be a prehistoric civilization, it is also possible, after all, there is a fault line in civilization, and many things are also faults, and they have not been inherited, so what leads us to now, should be regarded as a relatively backward human civilization, right? ”

I was also shocked, I didn't expect that these buildings, the materials used, I had never even heard of it! Not to mention seeing it!
