Yang Fan and Lang Jiu appeared at once and stepped on the ladder.

"Meet the Ten Fierce Demon Lords and the Demon Wolf Emperor!"

In that golden staircase, there were more than a thousand stunning beauties with different temperaments, and as soon as they saw Yang Fan and the others, they immediately knelt down and said respectfully.

A great power is also the top powerhouse in the demon world, and it must not be underestimated.

The palace master of the Black Moon Palace greeted Yang Fan and the others with the highest courtesy.

The golden light flashed slightly, and Yang Fan and the others were immediately welcomed into a large hall of the Black Moon Palace.

"Ten Fierce Demon Lords, Demon Wolf Emperor, please take a seat!"

In the main hall, the palace master of the Black Moon Palace smiled and invited.

The two powerhouses of the Crescent Moon Demon Lord and the Red Moon Demon Lord stood beside the Palace Lord of the Black Moon Palace.

In that hall, there are three jade tables, and on each jade table are various delicacies. Any plate of delicacies there is enough to make the powerhouses below the demigod go crazy.

Yang Fan sat down at a jade table with all kinds of delicacies.

Lang Jiu was like a guard, standing quietly behind Yang Fan.

"The Demon Wolf Emperor seems to be really a subordinate of the Ten Fierce Demon Lords! He was able to make a great power willing to be his subordinate, what a terrible guy. ”

The Palace Master of the Black Moon Palace had a sweet smile on his face, but there were waves in his heart. He has lived in the Demon Realm for more than tens of millions of years, and it is the first time he has seen the Supreme Demon of the King of the Demon Lord.

The Red Moon Demon Lord's beautiful eyes lit up, and a trace of excitement flashed: "The Supreme Demon is really his subordinate, so powerful!"

There was also a complicated light in the beautiful eyes of the Crescent Moon Demon Lord: "Amazing! He turned out to be not a powerful son-in-law, but a powerful master!

Yang Fan said: "Black Moon Palace Palace Master, I don't know why the evil puppet demon emperor attacked the Black Moon Palace?"

The Four Absolute Demon Emperor is a madman, and in order to take revenge, he can join forces with the evil puppet Demon Emperor to besiege the palace master of the Black Moon Palace.

However, although the evil puppet demon emperor is brutal by nature, he is a cunning and rational fellow. He basically doesn't easily provoke other powerful people.

The evil puppet demon emperor and the four absolute demon emperors joined forces to defeat the palace master of the Black Moon Palace. But unless there is a special reason, it is unlikely that they will want to kill Him and capture Him alive.

Yang Fan was also very curious about why the two Demon Realm powers attacked the Black Moon Palace.

The Palace Master of the Black Moon Palace pondered for a moment before saying, "They should be for the powerful cave mansion I found not long ago. It was a cave that was suspected to be left behind by the Supreme Demon King. ”

Since the evil puppet demon emperor has fled, it is no longer a secret that the palace master of the Black Moon Palace has found the cave mansion left by the Supreme Demon King.

Yang Fan's eyes lit up, and a trace of excitement flashed: "The Supreme Demon King's Cave Mansion!"

The Supreme Demon King is the terrifying powerhouse that has evolved to more than 90% of the power and supreme source of the supreme realm. Each of them is an old antique who has lived for countless years, and his strength is far above that of ordinary demon powers, and they are terrifying existences second only to the major demon emperors.

A supreme demon king with a supreme artifact that fits his own can even kill an ordinary power in an instant with a full blow.

The cave or treasure of the Supreme Demon King was definitely a treasure coveted by ordinary powers, and it was no wonder that the evil puppet Demon Emperor would join forces with the Four Absolute Demon Emperors to suppress the Palace Master of the Black Moon Palace.

Yang Fan smiled and said, "If I'm not mistaken!, that Supreme Demon King's Cave Mansion should be near here, or just below the Black Moon Imperial City!"

The Palace Master of the Black Moon Palace chuckled and said, "You guessed right!Ten Fierce Demon Lords, how about we explore the Cave Mansion of the Supreme Demon King together?"

Originally, the cave mansion of the Supreme Demon King, the palace master of the Black Moon Palace planned to explore it slowly. Anyway, his lifespan is almost endless, even if it takes a million years to slowly explore the cave of the High Demon King.

But now that the Supreme Demon King's Cave Mansion has been exposed, the Palace Master of the Black Moon Palace is also willing to join forces with Yang Fan to explore the Supreme Demon King's Cave Mansion.

Yang Fan said: "Okay! I need all the information of the Supreme Demon King Cave Mansion!"

The evil puppet demon emperor doesn't know when it will make a comeback. At that time, in addition to the evil puppet Demon Emperor, there will definitely be other great powers.

"Good!"

The palace master of the Black Moon Palace smiled, stretched out his hand, and a data crystal flew into Yang Fan's hand.

Yang Fan crushed the data crystal, and countless messages poured into his heart at once.

Yang Fan said: "Let's go now!"

The Evil Puppet Demon Emperor will come here with an unknown number of powerful and powerful people at any time. The sooner Yang Fan and his entourage explore that Supreme Demon King Cave Mansion, the better.

"Good!"

The palace master of the Black Moon Palace was also very decisive.

Originally, the Palace Master of the Black Moon Palace also planned to let the Crescent Moon Demon Lord or the Red Moon Demon Lord marry Yang Fan. After all, the Crescent Moon Demon Lord and the Red Moon Demon Lord are both rare peerless beauties. If the two of them marry Yang Fan, the Black Moon Palace can gain the support of a great power.

Once the Black Moon Palace is guarded by two great powers, it is almost as stable as Mount Tai in this demon domain, and no one dares to provoke it.

However, since Yang Fan wanted to explore the Supreme Demon King Cave Mansion, the Palace Master of the Black Moon Palace was also very welcome. After all, it was still a little difficult for him to explore the Supreme Demon King's Cave Mansion alone.

The palace master of the Black Moon Palace stretched out his hand and pointed at it, and a round of black moon suddenly appeared, engulfing the entire Black Moon Imperial City, and then sending it into the void and disappearing.

The palace master of the Black Moon Palace had also guessed that there would be more powerful people coming here in the future, and he could only send the Black Moon Imperial City away.

Otherwise, those great powers will definitely blow the Black Moon Imperial City to pieces.

As soon as the Black Moon Imperial City was sent away, only the Palace Master of the Black Moon Palace and Yang Fan and his party were left.

"Open it for me!"

The Palace Master of the Black Moon Palace stretched out his hand and pointed to the ground.

Countless mysterious spell marks surfaced, and a huge black moon seal spell appeared underground. It was that Black Moon Seal that blocked everything in that powerful cave mansion from being able to peep into.

Countless black lights shone brightly, and the Black Moon Seal Spell Seal collapsed in one fell swoop.

An ancient, mysterious, and inscribed with countless mystical spell marks suddenly appeared in front of the eyes of the Palace Master of the Black Moon Palace and Yang Fan.

"There is an incomparably powerful barrier open on this gate! With my strength, even if I hit with all my strength, it will be difficult to destroy. The most tricky thing is that even if you destroy this gate, it is very likely that you will lose the gate to enter that cave!"

"The best way to enter this gate is to obtain the key to it, or to draw the blood of the pure-blood descendants of its owner. Unfortunately, I can't do either of these methods. ”

"My original intention was to use time to slowly wear down the power of this gate, and find a way to open it when it is at its weakest. Now I can only take a chance!"
