The fat old cow looked at Lu Hao and asked, "Brother Lu, I don't know where your map came from?" This map is thousands of years old! ”

"Really? It's just that the terrain on this map is very weird, no wonder you can't find it! Lu Hao explained.

"Of course, everything has changed dramatically over thousands of years, but this map is underground, and it may not have been discovered yet!" The fat old cow suddenly explained.

"Huh? Why? Lu Hao asked.

The fat old cow explained: "Looking at the terrain, I must not be able to find it, but this pattern is marked with the location of its five elements, I think this five elements of the substance is very secret, maybe not ordinary people can find it!" ”

"So, Brother Niu, can you find out the location of this sword mark?" Lu Hao raised his eyebrows and asked.

The fat old cow smiled: "As long as there are five elements of yin and yang, I don't believe that I can't find it!" ”

"In that case, then please Brother Niu!" Lu Hao said with a smile.

"You're welcome, in fact, I'm also very curious about the location of this map!" Lao Niu said excitedly.

Because according to the mark of this map, this location is underground, since it is underground, it is likely to be a hidden underground palace, since it is an underground palace, maybe it is a treasure hiding place, so as a professional tomb robber, how can he not be excited.

Then they got on Gaibao's off-road vehicle, and the fat old cow began to observe the position of the five elements of yin and yang here in the desert.

Soon he came to get married, and the position of the five elements on this map is the same as the five elements of the desert, so the place marked on this map is likely to be in the desert area.

They had been looking in the desert for a day, and to their surprise, they followed the location of the five elements of yin and yang on the map, and the destination was getting closer and closer to the small town of Hitomi.

In the evening. They came to the small town of Hitomi, and the fat old cow finally gasped.

Because according to the marks on this papyrus map, the location of this underground palace is actually under the town of Hitomi.

Lu Hao was also surprised when he learned the news.

"Brother Niu, are you looking for it accurately, when this Tongtian town was first built, the underground must have been explored. If there is a dungeon underground, this must have been discovered a long time ago! Xiaobai said very skeptically.

"Yes! It's unlikely that there is a dungeon down there! Didn't you notice that there was an abnormality here on your Qiankun turntable? Gai Bao said.

Lu Hao nodded, this kind of analysis is indeed problematic, if the underground palace is in Tongtian Town, the people in the town here will definitely find out.

At this time, the fat old cow touched his chin and began to think, he pondered for a moment and suddenly his eyes lit up, and he thought of a question.

"I thought of it!" The fat man explained: "The location marked on this map is thousands of years ago, and it was a few years ago. There must have been a metastatic change in the underground here, after all, this is a desert, you know, if the underground palace exists under the desert, he must be slowly flowing with the crust of the desert, thousands of years, its movement is definitely not in the original location of Hitomi Town! ”

"You mean it's gone to the interior of the desert now?" Gebo asked.

"Not bad! According to the flow of the desert crust here, it is in a northeasterly direction! Then this dungeon must exist in the northeast of Hitomi Town! We look in this direction. I'm sure you'll be able to find the place where the dungeon exists! Lao Niu said excitedly.

Lu Hao was a little surprised, but his speculation and theory still had some truth.

Then several people drove northeast and began to search. The fat old cow's Qiankun turntable came into play.

Finally, they were more than ten miles away, and the fat old cow's Qiankun turntable suddenly turned rapidly, and the pointer first rotated in the forward direction and then in the opposite direction, and the frequency was very fast.

"Found it! This dungeon must be down there! Lao Niu couldn't help but exclaim.

They immediately stopped, got out of the car and watched everything happen. At this time, the desert is full of sky, and there is nothing special here.

"This is a desert in the sky, how can we find it, since it is a dungeon, there should be a gate to the dungeon!" Xiaobai said with a frown.

"Not bad! It's just that this sedge map doesn't mark the gate of the dungeon! Lao Niu said depressedly.

At this time. Lu Hao also frowned, he patrolled here, and there was no abnormality from the desert plane.

Lao Niu not only said: "My Qiankun turntable has sensed the location, it must be within a radius of one mile!" It's just that if we can't find the entrance, this dungeon is difficult to find, and after so many years, I'm worried that the specifications of the dungeon are likely to have turned into dust, if that's really the case, we'll be in vain! Lao Niu explained.

This map is thousands of years old, and if the dungeon is a desert dormitory, even the ancient artifacts inside may have turned into dust, after all, it has been too long.

Lu Hao was spinning nearby, and just as he reached one of the hollows, the silver hilt of the sword he pinned to his waist suddenly trembled.

"Huh?"

Lu Hao was a little surprised, and then immediately made a lap in the hollow, and finally determined that in one of the positions, the silver sword hilt jumped several times in a row.

Since this silver hilt is spiritual, perhaps it is something underneath that has sensed the hilt that causes the hilt to tremble.

Then he slammed his palm downward, and Qing You's palm immediately struck a huge crater underneath.

At this time, Lao Niu and the others also came over, and Lao Niu said, "Brother Lu has found anything abnormal?" ”

I saw Lu Hao squatting down and flicking the sand and stone with his hand in the giant pit, and a palm-sized round bluestone was suddenly revealed from below, and there was a connected stone pillar under the bluestone.

"Ahh The key to the dungeon! The old cow suddenly exclaimed.

As a professional tomb robber, Lao Niu certainly knows a lot about this kind of underground palace key, which is generally used to open the door of the underground palace.

"The key to the dungeon?" Lu Hao was surprised and asked, "Then how can I open it!" Is it spinning? ”

"Nope! Wait for me to check it out! ”

Then Lao Niu once again took out the Qiankun turntable and began to test it around, and after ten minutes, he found two identical bluestones within five meters of this bluestone, and the three bluestones formed a triangular shape.

"Haha! That's right! This door should be three keys! The old cow was excited.

Lu Hao asked, "Then how do we open these three keys?" ”

"According to my observations, if this is not a rotary type, it should be a foot pedal type, but it must be stepped down by three people together!" Lao Niu explained.

Lu Hao nodded and said, "Since this is the case, let's prepare to open the door of this underground palace together!" ”

Then Lu Hao, Lao Niu, and Black Tiger each stood in the position of the bluestone, and stepped down the bluestone mechanism together according to Lu Hao's gestures.

"Click!"

In an instant, the sound of bluestone grinding was heard, and the next moment something shocked them appeared.

I saw that in the center of their triangle, suddenly a huge cyan stone pillar appeared quickly from below the desert, full of five meters high and three meters wide in diameter, such a large stone pillar appeared, which shocked them.

But then, the cyan stone pillar suddenly spun around, and the next moment more than a dozen holes appeared on the stone pillar.

"Woohoo!"

More than a dozen bronze swords shot out quickly, towards Lu Hao, Black Tiger, and Fat Lao Niu.

"Gah?"

Everyone gasped, but they didn't expect that there was still an attack mechanism here.

Lu Hao quickly waved his hand, and with one palm, he knocked the five sharp swords that shot over to the ground, and the bronze sword broke in response.

And the black tiger also punched out, and a wave of qi directly smashed the five sharp swords that came towards him into pieces.

But the fat old cow was dumbfounded, and when he was frightened, Lu Hao's mental power directly stopped the sword in mid-air, and the sword fell directly to the ground.

Seeing the bronze sword fall to the ground, Lao Niu instantly breathed a sigh of relief.

"Holy! It turned out to be a trap! It's so damning! Lao Niu couldn't help but scold.

Lu Hao said depressedly: "I said that you didn't say that this is the key mechanism of the dungeon, how to make an attack mechanism!" ”

At this time, Xiao Bai was suddenly depressed next to him: "Oh, this is a bronze sword that is thousands of years old, and it is broken like this!" ”

I saw him squatting on the ground, looking at the broken bronze sword and depressed.

Lu Hao couldn't help twitching the corners of his mouth, and then the fat old cow observed on the top of the cyan stone pillar, at this time, the cyan stone pillar, the hole above was exposed, and it was pitch black inside, and nothing could be seen.

"Could it be that this is not the key mechanism that opens the door of the dungeon, it is impossible! It's no problem with this kind of mechanism! Lao Niu said suspiciously.

Then he said again: "Brother Lu, why don't you try again, you see that the three cyan mechanisms are now back in place!" ”

Lu Hao glanced at the three bluestone mechanisms below, and sure enough, the position where the bluestone mechanism was originally stepped on was now restored to its original position.

"According to my speculation, stepping on it for the second time is likely to open the door of the dungeon!" The fat old cow gritted his teeth and said.

"In that case, let's try again!" Lu Hao said with a smile.

Then Lu Hao came to the location of his bluestone mechanism just now, and the black tiger also walked to his position.

At this time, the fat old cow said to Gai Bao with a smile: "I always say that Lao Gai, why don't you come for me this time?" ”

"Ahem! Brother Niu, didn't you say that you would definitely be able to open the door of the underground palace this time! How afraid of danger! Xiaobai said with a smile.

"Didn't I just in case! I was shocked in a cold sweat just now! Lao Niu touched his chin and said embarrassedly.

Gai Bao didn't say anything, and walked directly to the bluestone mechanism.

The next moment, with Lu Hao's gesture again, the three of them stepped down the bluestone mechanism together.

At this time, the huge cyan stone pillar in the middle suddenly rolled again. (To be continued......)
