There are no luxurious palaces or other decorations in the majestic underground palaces, but only some earthen walls and stone walls.

However, in this slightly dark underground palace, there are criss-crossing passages, and if you look down from the sky, you can see that these criss-crossing passages seem to form some kind of obscure and mysterious formation.

And under the ground of these passages, there are strange black lights flickering, although these black lights are a little dim and not strong, but they always exude a terrifying fluctuation.

This place is one of the highest forbidden places in the Holy King's Palace, because this is where the eyes of the entire Kyushu Dragon Gate Array are located, and these places that emit black light are the nine veins of the earth.

It's just that now around this underground palace, there is still an enchantment, and the power of this enchantment, although it is not as strong as the Kyushu Dragon Gate Array, is not weak.

Before the Holy King and Ye Jiechen fell directly into this underground palace, the huge Silver Spirit Emperor Lion also shrank rapidly, turning into the size of an ordinary lion.

"This is the Nine Veins of the Earth under the Leaf Dust back then!" the Saint King explained.

"Yes, I know!"

Hearing this, Ye Jiechen nodded, but there was not much fluctuation on his face, the nine veins of the earth were laid by him, and he naturally knew the location.

"Let's go inside!"

The Saint King whispered, and immediately his figure quickly stepped forward, his palm spread, and a strong holy white light quickly surged out, and the last palm hit this enchantment.

Laugh at.

In an instant, countless light patterns immediately spread out along the palm of the Holy King's palm, as if they were unraveling this enchantment.

After a few moments, the power of the barrier gradually dimmed, and finally disappeared.

After lifting the barrier, the Holy King walked towards the dungeon.

And Ye Jiechen also followed beside him.

Inside the underground palace, it is quite spacious, and the passages that go out vertically and horizontally lead in all directions, it looks like a labyrinth, if an inexperienced person comes in, it is estimated that he will be lost in it.

"What should we do?"

The Saint King looked at Ye Jiechen and asked softly.

Although his strength is strong, he doesn't know anything about the formation, and before Fu Fuyun trusted Ye Jiechen so much, and even obeyed him, the Holy King naturally could only follow Ye Jiechen's instructions.

"Come with me!"

Ye Jiechen glanced at everything around him and said in a low voice.

Then, his figure directly bypassed these passages and walked towards the depths of this underground palace.

Seeing this, the Holy King didn't dare to stay, so he followed closely behind him, and the Silver Spirit Emperor Lion also ran in and followed behind.

Ye Jiechen seemed to know all the passages in this underground palace well, and his body constantly had to go around one passage after another, almost without thinking.

Seeing this, the Saint King's face was also full of surprise, he was also a little surprised that Ye Jiechen was so familiar with this underground palace.

However, he didn't ask much, now Fu Fuyun was fighting against the black dragon outside, although Fu Fuyun's strength was not weak, but the strength of the black dragon was not much worse, so he didn't dare to waste more time.

Ye Jiechen bypassed these passages all the way, and with each step, a mysterious fluctuation spread out from his body, as if he was probing the veins of the nine veins of the earth.

After a long time, Ye Jiechen and the Holy King finally arrived at the deepest part of the underground palace, but when the Holy King saw the deepest part of the underground palace, his pupils suddenly shrank, and his face was full of shock and shock.

I saw that in the deepest part of the underground palace, all the earthen walls and stone walls had completely disappeared, and some of them only stood nine black altars.

The nine black altars were suspended in mid-air, directly forming a fan-shaped shape, enclosing them, and in the center of this black altar, an indescribable black vortex appeared.

This black vortex is about a thousand feet in size, and the nine altars around it seem to have some kind of traction, a steady stream of black power, constantly from within this altar, and finally instilling into this black vortex.

And these powers are all absorbed by this black vortex, and this absorption has no end, it is like the entrance to an abyss world, just looking at it, and even people can't help but palpitate.

"What is this?"

The Holy King couldn't help but exclaim.

Since the day he served as the Saint King, he had never seen this strange black vortex in the underground palace, and Fu Fuyun had never told him.

No one would have thought that under the earth of the Holy King's Palace, there was such a terrible thing hidden.

The Saint King could sense that in this vortex, it seemed that an extremely large amount of energy had been accumulated, and this energy, even with his current strength, was a little terrifying.

"This is the eye of the Kyushu Dragon Gate Array, and it is also the final gathering place of all the spiritual energy of the nine veins of the earth, the dragon vein!" Ye Jiechen said in a low voice.

As the words fell, he continued to add: "Of course, this is also where the black dragon was born!"

Hearing this, the Saint King's heart suddenly shook a little, this was the first time he had seen the dragon vein, but what he didn't expect was that the black dragon was actually born from this place.

So, these nine black altars......

"Inside these nine black altars, there are nine dragon teeth, in order to draw the earth aura into this array, Ye Chen only built these nine altars back then!"

Ye Jiechen seemed to guess the doubts in the bottom of the Holy King's heart, so he explained.

When the words fell, he didn't waste any more time, his hands suddenly and quickly pinched, and he conjured up obscure and mysterious seals.

In the end, he directly slapped his palm on the ground below, and black light streaks quickly spread out along the ground.

These light patterns, like the patterns of a certain formation, spread out, and the nine black altars in front of them quickly spread out, forming a passage.

"You go in, use your maximum strength to pour Yuan Force into this black vortex!" Ye Jiechen said in a low voice.

Hearing this, the Holy King immediately stopped saying more, and walked in quickly, and then the majestic holy white light in his body was like a flood, surging out like madness.

Although the Saint King's current strength is not as terrifying as Fu Fuyun's, he is also the top powerhouse in this Southern Region.

Immediately, as soon as the holy white light poured in, there was even a faint vibration in this underground palace.

Then, the Saint King directly palmed at this black vortex, and the majestic and pure holy white light quickly poured into it.
