"Let's go inside!"

The palace master of the Black Moon Palace smiled slightly, strode to the gate in front of the palace, and pushed it hard.

Bang!

Although the palace master of the Black Moon Palace looked like a delicate and weak beauty, he was actually a supreme demon who could burst a star with his hands. With a strong push, a star would be bounced away. But the door only trembled slightly, and remained motionless.

The palace master of the Black Moon Palace, Liu Mei, frowned slightly, and said with a look of regret: "The Ten Fierce Demon Lords, I can only rely on you!"

There was an incomparably powerful barrier open in the palace of that Supreme Demon, and if you forcibly broke into that palace, you might touch the prohibition set by the Supreme Demon King, the Giant Heavenly Demon Emperor.

The prohibition set by the Supreme Demon King, the Giant Heaven Demon Emperor, is also very likely to be severely damaged, or to kill a lower supreme demon.

"Good!"

Under Lang Jiu's protection, Yang Fan came to the door and stretched out his hand to press it.

Countless main god evolution points were submerged into that gate, allowing Yang Fan to have a connection with that gate at once.

"Interesting!"

The corners of Yang Fan's mouth suddenly lifted slightly, and his heart moved, and the huge number of main god evolution points and supreme evolution points continued to submerge into that gate, and spread along that gate to the depths, all the way to the core of that world's cave mansion.

At the core of that world's cave mansion, a mysterious black light shone, and that mysterious black light was condensed by countless mysterious spell marks.

Under the erosion of the supreme evolution point, that mysterious black light began to be eroded inch by inch. However, that mysterious black light was the power of the Supreme Demon King, the Giant Heaven Demon Emperor, so the speed of erosion was very slow.

Even so, the mysterious black light was still eroded inch by inch until it was halfway eroded.

"It's only able to erode half! The Supreme Evolution Points are not enough! The Supreme Demon King really lives up to his name!"

When there were only 100 Supreme Evolution Points left, Yang Fan decisively stopped the erosion, and a trace of regret flashed in his eyes.

Yang Fan's main god has a lot of evolution points, but the supreme evolution points are very few. After all, refining a low-grade supreme elixir, he could only obtain about 5 supreme evolution points.

"Open the door!"

Yang Fan gave an order.

Click!

The doors of the palace opened.

A hint of curiosity flashed in the beautiful eyes of the Palace Master of the Black Moon Palace: "It's really amazing!What kind of ability is this?"

There are also countless strange abilities in the Demon Realm. The palace master of the Black Moon Palace was just curious, and did not ask. Because He knows that even if he asks, he may not be able to get an answer.

Yang Fan entered the palace with the palace master of the Black Moon Palace.

As soon as you enter the palace, you will be greeted by two rows of statues, two in each row, for a total of four. The four statues are the Green Dragon, the Vermilion Bird, the White Tiger, and the Xuanwu.

As soon as Yang Fan and the others entered, the four statues immediately began to activate rapidly, and four terrifying aura of the median power level diffused from the four statues.

A trace of solemnity flashed in the eyes of the Palace Master of the Black Moon Palace and said, "Oops! I underestimated the danger of the Supreme Demon King Giant Heaven Demon Emperor Cave Mansion! This is a world-class supreme artifact that can draw power from the Demon Realm and maintain all kinds of prohibitions here." Even if a billion years pass, there is no danger of running out of energy. Let's get out!"

The most powerful thing about those world-type supreme artifacts is that they can extract a huge amount of demonic energy from places like the Demon Realm or the Divine Realm to maintain the operation of the world.

Therefore, even if 100 million years have passed in the powerful cave mansion in those world-like supreme artifacts, the various prohibitions in it will not lose their power due to the passage of time.

Of course, the number of powers that possess world-class supreme artifacts is very rare, and even the supreme demon king or supreme god king does not have too many world-class supreme artifacts.

"Seal!"

Yang Fan's eyes flashed with coldness, and he snorted and stretched out his hand.

Four jet-black rays of light flew out of Yang Fan's hands and sank into the four statues.

The four statues shuddered? Immediately start petrifying again? It was re-transformed into four statues.

"That's okay? What kind of sealing is that?"

The Palace Lord of the Black Moon Palace was dumbfounded. He was also well-informed, but he couldn't see what kind of power Yang Fan had used, and he had sealed four powerful statues of the middle demon lord level in one go.

"Let's go!"

Yang Fan smiled slightly? Under the protection of Lang Jiu's dark enchantment? Walked straight to the cave.

The Palace Master's eyes flashed slightly, and he also followed.

The cave of the Supreme Demon King is vast and boundless? And it has not been visited, and there are all kinds of treasures everywhere. If an ordinary demon lord can get one? Satisfied? Make a lot of money.

However, the palace master of the Black Moon Palace is a great power, and he didn't even look at the demon master-level treasures in the cave of the Supreme Demon King.

After passing through the corridors, the medicine garden of the cave mansion suddenly appeared in front of Yang Fan and his party.

That medicine garden is vast, and above that medicine garden are thousands of stars that are beneficial to the growth of potions? Countless stars scattered below.

In that medicine garden? There are also countless medicine gardens that cultivate the main divine medicine and the demon divine medicine.

In addition, there were thirteen huge spiritual mountains in that medicine garden, and each of them had a supreme divine medicine growing on top of each spiritual mountain with a diameter of up to 10,000 kilometers.

On top of one of the spiritual mountains, there is a golden dragon vine that is like a dragon, thousands of miles long? At the top of the golden dragon vine grew three golden fruits.

"Top-grade Supreme Elixir Supreme Golden Dragon Divine Fruit!"

As soon as the palace master of the Black Moon Palace saw those three fruits, his eyes suddenly lit up? There was a burning glow in his eyes.

If the palace master of the Black Moon Palace used the power of the Black Moon Imperial City, he could also cultivate the inferior supreme elixir in the demon realm. That high-grade supreme elixir? He has not even seen it.

The top-grade supreme elixir is generally only in the hands of the supreme demon king and the major demon emperors. The Seven Pillars under the command of the Southern Demon Emperor may also have it.

That top-grade supreme divine elixir supreme dragon divine fruit has extraordinary power, which can help the palace master of the Black Moon Palace break through and advance to become a median supreme demon lord!

The palace master of the Black Moon Palace has advanced to the supreme realm, I don't know how many billions of years? But he still can't advance to the middle supreme demon lord. The Supreme Golden Dragon Divine Fruit was the only treasure he had ever seen that could allow him to advance to the Middle Supreme Demon Lord.

The Palace Master of the Black Moon Palace couldn't help but take a step forward? Suddenly appeared in front of the golden dragon vine.

Yang Fan frowned slightly and reminded: "Be careful!"

In that moment? The golden dragon vine burst out in an instant, opening its bloody mouth like lightning, and frantically biting at the palace master of the Black Moon Palace.

A terrifying aura of mid-to-high-level emancipation permeated from the body of the golden dragon vine.
