When Li Xiangnan picked up the skull, there was no abnormal phenomenon like Zhimo.

However, the power fluctuation of the runes on the skull was very strong, and under its influence, the spirit bones near the cave passage all trembled slightly, as if they were resonating with this skull.

It seems that the defensive formation formed here will have some connection with the owner of the skull that Li Xiangnan picked up.

With such a guess, Li Xiangnan picked up all the spirit bones with runes, observed and studied some of the traces that had been left there, and cleaned up the mountains of bones there, vacating some places.

When Li Xiangnan filled those vacant positions with those spirit bones, and finally placed the skull in the innermost position, there were finally some changes.

Just using the formation posed by those spirit bones can produce some subtle changes, which is really amazing.

After that formation was formed, the runes on those spirit bones would produce a wave of power.

Perhaps under the influence of his master's will, when the runic power of those spirit bones gathered, they gradually formed a guardian circle in front of the cave passage.

At this moment, in the very center of the guardian circle, a vortex slowly formed.

The vortex of power is so magical that it will gradually manifest itself as a door of pure power from within, and then place it in the passage of the cave, making it even more solid and difficult to break.

Seeing this scene, Li Xiangnan was not surprised but rejoiced.

He found the very center of the door that had been made up of pure power. There's a gap there, and if you find something to embed it, you're sure to be able to open the cavern passage.

Zhimo watched quietly from the side as the cave changed.

When she saw the door generated by pure runic power, she frowned, thinking that it would only make the cavern passage stronger, and it would be easier said than done.

Moreover, although the door showed a slot, the key could not be found so lightly, and Li Xiangnan's move not only did not work. It makes it more difficult.

So Zhi Mo said puzzledly: "It seems that the formation formed with these spirit bones will not have much effect. The key is the center of the door, which requires a key that can be opened, but that key ...... Ah, this is ......"

But Zhimo was talking. I suddenly saw Li Xiangnan take out something and come out. This made her recognize it quickly. couldn't help but be taken aback, and said, "This, this is the emperor's decree." How do you have this thing? ”

Li Xiangnan was a little surprised when he heard Zhimo's exclamation.

The token he had taken out was the one he had gotten from the ghost's collection and the teleportation compass after he had killed him.

It's just that he figured out that the compass was a space teleportation key left over from the three ancient cultivation sects that could leave the earth and go to the secret realm, but this token was the same thing, and he never figured out what it was and what role it would play?

Until this moment, when Zhi Mo shouted the 'Human Emperor's Decree' in surprise, Li Xiangnan couldn't help but be taken aback, and said, "What do you say, do you recognize this token, this is the Human Emperor's Decree?" ”

Zhi Mo's eyes at this moment looked at the human emperor decree that Li Xiangnan took out, her eyes were full of shock, she looked at the human imperial decree, and then looked at Li Xiangnan, after a long time, she finally said: "That's right, this is indeed the human emperor's decree, it is recorded in ancient books, I have seen it, and I am very impressed!" ”

Li Xiangnan said: "Then what is the effect of this person's imperial decree, I just saw that the hole on the power gate generated here is very consistent with the token I picked up before, so I want to take it out and make a real ......."

Zhi Mo said: "The Human Emperor's Decree is a product left over from the ancient barbaric era, there are three of them, one of which is the Heavenly Dao inheritance and is not born, and the other has been damaged, leaving only the last one to circulate in the hands of the human emperors of the past generations.

In today's world, this human imperial decree may not play much role on the earth, but in ancient times, it was a token held by the kings of the human tribes, and it was also a symbol of status, with supreme authority.

In addition, this decree can call on the entire human tribe to serve him, and he is also the key to unlocking the treasure house of the Human Emperor left over from the primeval barbarian period.

However, at the end of antiquity, the Terran tribes were fighting among themselves, and they were in a period of division, and this human imperial decree was also something that the major powerful Terran tribes tried to unify the human race, and they all coveted and wanted to obtain, as long as this human imperial decree was in the world, it was enough to cause a huge catastrophe......"

Speaking of this, Zhi Mo's expression was very solemn, and said: "Xiang Nan, since you know that this is the emperor's decree, from now on, you must not show it lightly in front of the world, although there may not be many people who know the secret of this person's imperial decree now, but there are no absolutes in the world, once the news leaks, he will bring you death!" ”

Hearing Zhi Mo's admonition, Li Xiangnan finally figured out the role of this person's imperial decree in his heart, and naturally he would treat it with caution.

However, at the moment, the position that appeared on the door blocking him was quite consistent with the imperial decree of the person he was holding, and there was no third party here, so Li Xiangnan naturally did not have so many concerns.

So, Li Xiangnan embedded the human emperor's decree in the vacant position in the door, which just coincided, and it was exactly the same.

And it was at this time that a magical sight finally happened.

I saw that after the human imperial decree was embedded in it, it seemed that the mysterious power contained in it was activated, making this human imperial decree shine brightly, like a golden sun, illuminating the surrounding area of gold.

At the same time, after the Human Emperor's Decree was activated, nine golden dragons suddenly conjured up from the dragon patterns on that face, constantly surrounding the Human Emperor's Decree, and at the same time, they were constantly absorbing the power generated by those spirit bone runes.

Those golden dragons guarding the Emperor's Decree would grow a little stronger every time they absorbed the power of the spirit bone runes in the formation. It looks very majestic and mighty.

And the refining furnace that had been floating in front of him, at this time, in front of the nine golden dragons, suddenly became like a quail, trembled a few times, and then fell straight into Li Xiangnan's hand, and there was no more movement.

It's just that after the power generated in those spirit bone runes was gradually devoured by the golden dragon, the runes on those spirit bones gradually began to fade, and finally after they disappeared, the spirit bones were no different from ordinary decaying white bones. Instantly turned into a pile of bone meal. Falling in all directions.

Not only that, but even the runes on the bones of the large number of alien beasts around them were gradually devoured and absorbed by those guardian golden dragons at this moment, thus turning into a pile of bone powder. The power gained from that human imperial decree is even stronger.

At this time. Those golden dragons devoured the power of all the spirit bone runes around them. He did not commit any offense to Li Xiangnan and Zhimo, and then flew directly out of this dark abyss, swimming between the blue and gray heaven and earth. and devour the mysterious power contained in the spirit bones with runes scattered on the battlefield of the ruins.

Li Xiangnan and Zhimo opened their mouths wide at the moment, witnessing this magical scene together.

However, they didn't bother to look at the nine golden dragons that flew out and were devouring the power of spirit bone runes everywhere in the ruins, because they saw that the door that had been formed by the convergence of pure rune power before was slowly disappearing.

And at the same time as the door disappeared, in the interior of the cave, I saw a ray of light slowly penetrating the passage, thus shining through.

At first, the light emitted by the guò cave was very fine, but the light contained a powerful force, very sharp, and it directly penetrated the cave passage, turning the incomparably hard rock into a cloud of dust.

In this way, after about three or five breaths, when the light gradually faded, the passage of the cave was opened.

What unfolds in front of Li Xiangnan and Zhimo is a mysterious passage that leads to nowhere.

Li Xiangnan was very surprised to see that the blocked passage was opened under such circumstances.

But at this time, he could also feel a very primitive and pure aura emerging from the depths of the mysterious cave, as if something was calling him.

Li Xiangnan planned to go in to find out, and he wanted to put away the human emperor's decree.

It was only when he stretched out his hand to him that he was suddenly rebounded by a force, and the man's imperial decree was still suspended in mid-air and motionless, with a golden light.

Rise!

However, Li Xiangnan's move seemed to have stimulated the golden dragon wandering outside and devouring the power of the spirit bone rune.

I saw a golden dragon let out a dragon groan, flew back like lightning, and did not attack Li Xiangnan, but surrounded the human emperor's decree, guarding the human emperor's decree.

Seeing this situation, Zhi Mo couldn't help but sigh and said, "It seems that the guardian golden dragon in this person's imperial order will not stop until the original power left in this ruin is devoured, I am afraid that this ruin will completely turn into a fragment of desolate ruins from now on!" ”

"Why is this happening?" Li Xiangnan said softly.

Zhi Mo said: "The Human Emperor's Order has been in the world for too long, and the power in it has almost dissipated.

And this time, you inadvertently took out the Human Emperor's Decree, and the formation condensed by the spirit bone runes here was inspired, and the power of its guardian golden dragon was stimulated.

It just so happens that the bone runes left here are all from the ancient wilderness, and the power contained in the spirit bone runes is very primitive and pure, which is exactly what is needed to protect the golden dragon, and in order to strengthen the protection of the emperor's order, the guardian golden dragon naturally has to suck up the original power here. ”

After hearing these words, Li Xiangnan didn't go to collect the emperor's order, he looked at the mysterious cave passage, and sensed the summons coming from inside, and couldn't help but say: "Let's go and have a look first......

Zhimo nodded, and the two stepped into the cave passage.

But then, at the entrance of the insight path, a breath suddenly poured out, and the passage disappeared in an instant, disappearing into the darkness without leaving any trace...... (To be continued......)
