The color of the palace group is the same as what he saw on the mountain before.

But this palace complex is countless times larger.

Attics and manors with carved beams and painted buildings are rising and falling in this palace group, stretching for thousands of miles.

"This architectural model is a bit like the imperial palace in the mortal world!"

Ye Chen stroked his chin and said thoughtfully.

Ye Chen decided to continue to look, but at this time there was an invisible formation outside the palace group covering it.

In Ye Chen's perception, this formation is countless times stronger than the one arranged at the entrance of the dark world.

"It seems that this palace group is the core position of the Thirteenth Palace of the Underworld! I wonder if there are any powerful existences here!"

Since he decided to go in, Ye Chen began to think about the way to go in.

He is very proficient in the way of formations.

As the founder of the Holy Ruins who created the Five Daoes, Ye Chen has a wide range of knowledge and is appalling.

Ye Chen slowly walked around the palace group and circled around.

Finally, a few hours later, a smile appeared on the corner of his mouth.

"So that's it. This formation actually borrows from the mountain protection formation I designed at the Magic Sect! No, it cannot be said to be a reference, it should be a copy! From the techniques of array layout, to the various array texts and array materials, it is exactly the same as the formation I arranged at that time!"

Ye Chen shook his head and laughed. He didn't expect to see his previous works in this place.

He really didn't know whether he should feel grateful or sad.

His own inheritance was actually stolen by the people from the Underworld.

"Since I have encountered this big formation this time, I will take it back!"

After saying that, Ye Chen took off in the air and reached directly above the palace complex.

At this moment, his eyes burst into divine light and he looked down at the formation under his feet.

All the structures of the entire formation were clearly visible in his eyes.

Then Ye Chen pointed a little in the void, and a sword light shot towards the formation below.

The angle of the sword light was very tricky. When it touched the formation, the sword light actually twisted a few times.

Then he quietly penetrated the formation.

After entering the formation, the sword light speed did not decrease and slashed towards a formation text in Ye Chen's eyes.

As the formation pattern disappeared, the large formation that was shrouded outside the palace group was slightly shocked.

The formation barrier, which was originally several feet thick, became thinner to the naked eye.

But it did not disappear completely.

At this time, the formation barrier is still about ten feet thick.

Ye Chen's movement did not stop at this time. He shot out several sword lights in his hand and landed in the formation.

As the formation texts were cut down one by one, the formation outside the palace group quickly became thinner.

Finally, when Ye Chen fell the last sword light, the formation in front of him was like a bubble.

With a slight "bang", it disintegrated.

Looking at the palace group that had lost protection in front of him, Ye Chen nodded with satisfaction.

Finally, he fell down and stepped onto the ground of the palace complex.

He had already figured out the layout of the palace complex before.

After falling down, he walked towards the main hall of the palace group.

When he came to the gate of the main hall, what appeared in front of him was a huge palace with a closed door.

Ye Chen looked up and saw a plaque hanging on the gate of the hall.

The plaque reads "Thirteen Palaces of the Underworld" and four large dark golden characters.

"The Thirteenth Palace of the Ming Dynasty? It is also called the Thirteenth Palace of the Ming Dynasty. It seems that this palace group is the predecessor of the Thirteenth Palace of the Ming Dynasty. It is indeed much more grand than a lonely hall built in the belly of the mountain!"

Ye Chen was moved, but he was alert but did not let go.

He stood at the door of the hall, and his spiritual sense radiated out and penetrated into the entire hall.

The formation is still arranged outside the hall.

But what made Ye Chen funny was that these formations were still arranged by plagiarizing the formations he left before.

The strength of these formations is much weaker than the large formation outside the palace group.

So Ye Chen didn't have to deliberately break the formation. As long as his spiritual sense rushed, he would break through the formation.

Although his spiritual sense entered the palace, he finally saw what was in the palace.

The entire hall was empty, and there was a throne at the top, and there was a person sitting on the throne.

There is nothing else in the entire hall except this person.

Even the pool under the throne steps has dried up.

Perhaps because of the protection of the formation, after so many years, the hall is still spotless.

Ye Chen restrained all his spiritual sense and prepared to concentrate on the figure.

It's easy to observe whether this person is dead or alive.

If he is alive, how strong is he? Can he successfully escape?

He came here this time to pass the time, and there was no very important purpose.

If he encounters any trouble, this is something he doesn't want to see.

And at this moment, the figure's eyes suddenly opened.

Ye Chen was shocked, but he did not escape immediately.

Because in his perception, the breath of the figure was immersed in his body.

According to the slightest residual fluctuation that penetrates.

Ye Chen felt that this figure's cultivation level at its peak should be at the fifth level of the Underworld Emperor Realm.

This is a real master!

You know, the current cultivation level of the Emperor of the Underworld, which is now unified in the entire Underworld, is only at the sixth level of the Underworld Emperor realm!

From this we can see how terrifying and rare the cultivation level of the fifth level of the Underworld Emperor Realm in the hall is!

The reason why Ye Chen did not retreat was because he still felt that there were serious injuries left on this person's body.

So, his aura is now very sluggish.

Although he has the power of the fifth level of the Underworld Realm, his true strength may not be able to exert much.

Moreover, this person emitted a cold and dead aura.

This kind of death energy is different from the heart of giving up from people in the underworld.

It is the dead aura emitted from this person himself.

This indicates that the person in front of him has little lifespan and is about to run out of energy and lights.

Then what did Ye Chen fear? He had nothing to fear!

At this moment, the figure in the hall slowly opened his mouth.

Then, a hoarse and dry voice passed into Ye Chen's ears.

"Why are old friends wandering outside the door when they visit? Although my hall is simple at this time, a seat can still be taken out. Guests may as well come in, let me tell you and I?"

Ye Chen frowned.

The man just now claimed that he was an old friend.

But in his spiritual world, he was not familiar with this person's appearance at all.

The figure sitting on the throne in front of me was withered and thin, with wrinkles all over her face, extremely old.

Such a look has no recognition at all.

That was when Ye Chen felt the other person's breath just now.

He also found that the other party was not familiar with the aura emitted by him.

So he couldn't remember who the other party was.

Since he couldn't remember, he chose not to think about it.

So he pushed open the door of the hall and walked in.

When he stood in front of the thin figure.

The thin figure looked at Ye Chen and made a very ugly smile.
