When Du Fei saw everything in front of him clearly, he found that he was already in front of a strange valley at this moment, and the air around him suddenly became a little hot for no reason, as if Du Fei was on a fire.

"Is this the bottom of the hall? It seems that this is another space carved out on its own. Du Fei was not surprised at all by this kind of change, if the ancient royal family didn't even have the ability to open up space, then their so-called inheritance would be a little too bad.

After sweeping his eyes around, Du Fei found that all around were empty, like a desert, and the only more conspicuous place was the valley in front of him. And at this moment, under his feet, is a winding path, and although this path is crooked, looking at this shape, it leads directly to the depths of the valley in front of him.

"Xiaobai, what do you think?" Du Fei stared at the scene in front of him and said lightly.

"According to this shape, this should be the important place of the ancient royal family back then, if there is no organ prohibition in this kind of place, even if you are killed, you will not believe it, but, I don't think there will be any small fight at present, in the hands of the ancient royal family back then, if there is a mechanism ban, it must be extremely obvious, and it is also extremely sinister. There were no people around here, but Xiaobai jumped out without any scruples, and immediately stretched his waist.

"Well, let's go, then. Hearing this, Du Fei nodded slowly, and then walked slowly along the path cautiously. After walking for a while, Du Fei found that although the surroundings were weird, there was really no danger, just like what Xiaobai said, the ancient royal family seemed to disdain to set up any petty bans.

Walking slowly like this, after a while, Du Fei walked to the front of the valley, and immediately saw that a black stone tablet was standing directly in front of the path, with eight strong characters on it: "The royal family, the trespasser is dead!"

Du Fei frowned slightly and stared at this scene, and after a while, he could be considered to have some understanding, it seems that only after entering this valley can he be regarded as reaching the so-called critical place. It's just that since this ancient royal family has erected such a stone tablet here, it is naturally not for decoration, but just to warn those who come after. It's just that since it has reached this point, it is obvious that no one will back down.

After slowly staring at the stele for a moment, Du Fei slapped his hands lightly, and suddenly wisps of true qi quickly wrapped around his body, and then, Du Fei's spiritual power also spread out quickly. After making preparations, he sneered, and immediately raised his feet and walked over to the side of the stone tablet.

Although this stele looks plain, but after taking a step, Du Fei found that the scenery around him had changed drastically, and the original winding path was barren all around, but I don't know why, after stepping into this stele at this moment, he found that there were more trees and flowers around. It's just that these trees and flowers are a little yellow, as if there is an extreme lack of water here.

After staring at the scene for a moment, Du Fei took a breath and continued to walk slowly towards the front, that is, the interior of the valley.

"Roar—"

As Du Fei marched, the little tiger who was originally sleepy in his arms seemed to sense something, and his body moved and woke up, but it was still shrunk in Du Fei's arms like a kitten at the moment, and then his eyes glanced around with a little uneasiness.

Du Fei patted its body lightly, and glanced at Xiao Bai, and a trace of different color flashed in each other's eyes. This little tiger usually only wakes up when he perceives some kind of danger, and if you look at it this way, the royal forbidden land in this valley is really something amazing.

It's just that although there is such a thought in his heart, he has worked hard to obtain the qualification to obtain this ancient royal inheritance, and Du Fei will not retreat no matter what. So although his feet were a little slower, he still walked forward without delay.

After walking for about a few tens of meters, the path bent slightly, and in an instant, a huge clearing appeared in front of Du Fei's eyes. And the moment this clearing appeared, an ancient aura suddenly rushed to the face, and people couldn't help but shrink slightly.

After Du Fei took a slow breath, he calmed down, and then his gaze quickly swept towards the center of the clearing, and then, a wisp of different color flashed in his eyes.

At this moment, in the center of this clearing there is a huge circular building. The bottom of the building hangs in the air, and twelve huge stone pillars carved from white marble hold up the entire building, suspended in mid-air. And each of these white marble pillars looks like there are at least a dozen people who can hold them together.

On top of this white marble pillar, it is as if a huge stone is directly carved into a platform, on the platform, there is a tower-shaped building, the tower-shaped building looks from a distance, it seems to be as high as three floors, but the height of each layer is extremely exaggerated, if you look at it roughly, the first floor is nearly 100 meters high.

From a distance, this building does not look like it should be in the world, as if it is like a sharp sword, and it is directly piercing the sky. Looking at this thing, Rao Yi was calm with Du Fei, but he suddenly had the illusion of how small he was.

Du Fei took a deep breath, and there was a flash of thought in his eyes, a building of this scale, he had only seen it in the thousand-year-old ice realm, so if he expected it well, this building might not be left by the ancient royal family, most likely, the existence of this building was a little older than that ancient royal family.

After Du Fei settled down, he took a breath and said in a low voice, "Xiaobai, do you know what this thing is?"

"There is no similar information in the system, it's just ......" Xiaobai closed his eyes for a moment before hesitating.

"Just what?"

"But if I'm right, this should be an altar... Because of the shape of the type, I seem to have seen it. Xiaobai's face was also a little confused, obviously it was extremely uncertain about this statement.

Xiao Bai's hesitant statement made Du Fei frown slightly, but at this moment, even if there is a lot of danger in front of him, since he has come to this point, this so-called ancient altar, then he has to go in and break through no matter what.

After staring at this ancient altar for a moment, Du Fei's soles lightly stepped on the ground, and then his figure instantly suspended in the air. It's just that after flying up for a while, Du Fei felt that his whole body sank, and his figure in mid-air smashed directly to the ground, directly blasting out a deep hole on the ground.

"It's... ......Sensing such changes, Du Fei quickly recognized what was going on, but these changes made his mood more and more complicated. On the one hand, the more weird this place is, the better the things inside will naturally be, but on the other hand, if this place is too weird, then even with Du Fei's ability, it will not be easy to get any benefits from it......

Therefore, Du Fei was not in a hurry to continue moving forward at this moment, but after muttering for a while, he turned around and quietly stared at the ancient altar in front of him.

The ancient building in front of you is so majestic, and the tower-shaped building above it is even more attractive.

Du Fei stared at it for a moment before he sighed and said, "Xiaobai, how do you feel now." ”

"Still no, it's just that the things in there are definitely not simple. Xiao Bai frowned and said in a low voice.

And at this moment, the little tiger in Du Fei's arms also let out a low roar, and his voice seemed to be full of a bit of urgency.

"Whew-"

After taking a slow breath and being silent for a while, Du Fei suddenly waved his right hand, and suddenly saw a figure behind him. Obviously, under such circumstances, even Du Fei didn't dare to have any reservations, and had already summoned his hole card Lingdannu.

At this moment, Ling Dannu's face as indifferent as a dragon cypress did not have any superfluous expression, Mu Ran's eyes were staring ahead, and there was no color in his eyes.

And after seeing the Lingdannu, Du Fei was a little relieved, and then he waved his hand easily, signaling Xiaobai to control the Lingdannu, and only then did he move the soles of his feet, and his body had already swept towards the front quickly. And behind him, the figure of the elixir also followed as quickly as a ghost.

It didn't take long for the two of them to reach the surroundings of this ancient altar, and when they got closer, they found that there was a wide stone staircase directly in front of this ancient altar. This stone staircase is also carved from white marble, and when you look at it closely, it seems as if the stone staircase is integrated with the platform above.

Du Fei stepped on the stone steps with an indifferent face, and then the soles of his feet moved, and his figure had already jumped up.

It was not difficult to climb dozens of stone steps, so after less than a moment, Du Fei had already reached the platform. When he reached the top of the platform, he could see clearly that the tower-shaped building he had just seen below occupied only one-third of the space of the platform. However, even if the building is only one-third of the platform, it is still a little tall beyond imagination, and from a closer look, you can see that this stone tower is made of pieces of fiery red jade the size of a person, and it is obvious that the person who built this thing must have almost unlimited power. Otherwise, such a building could not be built by an ordinary family, dynasty, or sect.

However, no matter how unbelievable this building was, it was nothing more than that, and the most strange thing for Du Fei was that since he entered this valley, he had reached this point all the way, as if there would be no danger anymore. But on the contrary, there is always a sense of vigilance in his heart, and this kind of illusion of fusion really makes all kinds of thoughts in his heart entangled, and it is extremely strange.

"Master, it's already here, let's go!" Behind Du Fei, Xiao Bai hesitated for a moment before speaking in a deep voice.

"Hmm. Du Fei nodded slowly, and then threw all kinds of thoughts out of his head, and then he settled down, and his eyes carefully scanned around, and then he easily found the way to enter the ancient altar in front of him.

This tower-shaped altar is as a whole, and there is not even a mosquito-sized hole on the outside, only a low doorway that can almost be passed through by one person directly opposite the stone steps, and at this moment there are layers of faint golden light on this doorway, which is obviously some kind of prohibition above it.

Du Fei walked in slowly, but he didn't act immediately, just stared silently ahead, and only frowned slightly after a while, and said to himself: "It's exactly the same as the prohibition of the outside world?"
