Not long after, the Emperor of the Hu Kingdom took Li Changsheng into a relatively quaint palace in the depths of the palace.

Judging by the design of the palace, it is likely to be hundreds of years old.

After entering the quaint palace, the Emperor of the Hu Kingdom used a dragon-shaped token to open a mechanism, and a stepped passage appeared, winding downward, hundreds of meters long.

At the end of the passage, there was a gate made of unknown metal, with a dense ban attached to it, and a powerful forbidden circle, and they seemed to be matching.

Even if it is a king, I am afraid that he will not be able to break these prohibitions and forbidden formations in a short period of time.

"Your Majesty, this is the Nine Sons Serial Forbidden Formation. ”

Seeing that Li Changsheng was a little interested, the Emperor of the Hu Kingdom couldn't help but explain.

Of course, there is no in-depth analysis of the Nine Sons Serial Forbidden Formation.

In the memory of the first headmaster, there is some information about this access control array.

This is a special forbidden formation that combines illusion, defense, and offense, and if you want to break this forbidden formation, you must break the nine forbidden formations that make up the forbidden formation at the same time, which is also the reason why it is called the Nine Sons Serial Forbidden Formation.

If there is a suitable treasure suppression array eye, and the high-level demon core is invested regardless of loss, it can also enhance the power of the Nine Sons Serial Forbidden Array.

It's a pity that the memory of the first headmaster only has the basic information of the Nine Sons Serial Forbidden Formation, and there is no information on the formation of the formation.

Li Changsheng didn't feel a pity, because in the memory of the Treasure King, there were several forbidden formations that were no worse than the Nine Sons Chain, and even stronger.

In addition to the Nine Sons Serial Forbidden Formation, Li Changsheng also discovered the Bloodline God Forbidden.

If you want to open the Nine Sons Serial Forbidden Array, you not only need a token, but also a bloodline, otherwise it will lead to unpredictable consequences.

At this time, the Emperor of the Pot Kingdom pierced his finger and pressed it on the position of the bloodline god forbidden on the metal gate.

In addition, the emperor of the pot country also took out the turquoise jade seal.

This jade seal is still a quite good treasure, judging from the feedback of spiritual power, it has reached the top heaven and earth treasure level, as long as it goes further, it can become a world wonder.

The jade seal spun around, releasing a band of light that landed on the Nine Sons Serial Forbidden Array.

Under the double combination, the Nine Sons Serial Prohibition and the Bloodline Divine Prohibition disappeared one after another, and the metal door began to slowly open, revealing the scene inside.

It was a small secret room with only a table and a box on it.

Not surprisingly, the box should have a fire rule crystal.

For the sake of safety, Li Changsheng never let down his guard, after all, there is a chain of nine sons forbidden here, if there is any hidden killer feature, there is really a possibility of overturning.

Even if the probability is very small, Li Changsheng still adheres to a cautious and cautious way of dealing with the world.

After entering the secret room, the emperor of the pot country carefully opened the box of the table man? Revealing a crystal clear? Slightly hovering above the box.

This crystal contained a special power, like the center of the world, which made Li Changsheng's gaze involuntarily focus on the crystal.

Is this a hexagonal crystal? It was filled with fiery red clouds, which looked similar to the Upanishads crystal? But the nature of the power contained is more than a notch higher.

This force is the so-called rule of fire, a force that overrides the source of the Upanishads, and only by mastering the rules? in order to achieve a demon emperor-level demon pet.

Li Changsheng checked it? After discovering that there was no magazine present in the crystal? Are you sure this is indeed the crystallization of the rules of fire? And not defective.

Although the rule crystallization of defective products can also assist the demon pet to comprehend the rules, the effect will undoubtedly be greatly reduced? Not to mention the value.

The Emperor of the Huguo Country couldn't help but be full of reluctance, after all, this was the most precious treasure obtained by his ancestors, because the royal family had not given birth to a two-character king, so it had been idle here, ready to be used again in the future.

It's just that I don't know who leaked the rumors, and the Night King knew about the existence of the rule crystal, which led to a series of evil consequences.

In order to continue the royal family and safeguard the interests of the royal family, the Emperor of the Hu Kingdom and the King of Butterfly had to give this treasure of the Zhenguo that had been treasured for hundreds of years to Li Changsheng.

"Your Majesty, it's yours now!"

Even if he was reluctant in his heart, the Emperor of the Hu Kingdom finally had to hand the Fire Rule Crystallization to Li Changsheng.

"I will keep my promise!"

Li Changsheng solemnly took over the crystallization of the rules of fire, since he had been paid, he would naturally keep his promise, otherwise if he broke his promise, it would seriously hit his prestige.

As for this piece of fire rule crystal, Li Changsheng had already chosen the 'master'.

When the emperor of the pot country announced in public that he would give the fire rule crystallization to Li Changsheng, this fire rule crystallization became a hot potato, and Li Changsheng naturally did not intend to keep it in his hands, after all, he had just become the king, and there was still a long way to go from the two-character king.

If he kept this piece of fire rule crystal, it would definitely attract the prying eyes of many powerful people, and then cause many disputes, which would seriously threaten his life.

Rather than this, it would be in his best interest to exchange this piece of Fire Rule Crystallization with the needy Twin Character King in exchange for some treasures that could increase his strength.

As for the candidates, who else can there be besides King Aoki.

Li Changsheng only knew two two-character kings, one was the Night King, and the other was the Aoki King, the former belonged to the mortal enemy, and he seemed to have only one choice, the Aoki King.

Of course, Li Changsheng also considered using the rules of fire to crystallize and befriend the leader of the Human Emperor Mansion with a higher status than King Aoki after joining the Human Emperor Mansion.

It's just that this idea is just thinking about it, he is not so stupid, after all, he was introduced to the Imperial Mansion by King Aoki, if he joins the Imperial Palace, it must be the family of King Aoki, and there is a great possibility of accidents happening in this way, and at the same time, it will not be a person inside and out.

Arguably, Aoki is his best candidate for trading at the moment.

After leaving the ancient palace, the Emperor of the Hu Kingdom opened his mouth and asked, "Your Majesty, when are you going to join the Butterfly King?" ”

"Without further ado, I'm going to leave now!"

Li Changsheng knew very well in his heart that the longer the Fire Rule Crystallization was left by his side, the more strong people who would get the news would fight him, so he had to join the Human Emperor Mansion as soon as possible.

As for why he didn't trade with King Aoki before joining the Human Emperor's Mansion, firstly, it was for the sake of safety, and secondly, it could be exchanged for greater benefits.

"By the way, what about the demonic plague in your Hu Country?"

"Now the Hu country is in the midst of internal and external troubles, and the strong are seriously understaffed, and they can only be slowly subsided, but they have suffered the people. ”

The Emperor of the Hu Kingdom showed a compassionate expression, and he didn't know whether he really cared about the people, or just pretended like most emperors.
