in the door.

Li Xuan's divine thoughts are like a tide, passing through one door after another, in this independent space, the vast divine thoughts like the sea will not be suppressed by the power of heaven and earth at all, and they will expand unscrupulously!

Dilate!

This was the first time since Li Xuan returned to Earth that he had used the power of the Immortal Emperor's divine consciousness in all directions, and almost instantly, he had passed through trillions of portals.

However, to Li Xuan's surprise, the space inside this door seemed to have no end, and both the depth and breadth were far beyond the current earth.

It's like a universe!

Such a discovery made Li Xuan silent.

However, although the divine mind could not cover the end, in the process of expansion, he found many very interesting things.

The next second.

Li Xuan appeared behind a door.

It's a grave.

To be precise, it is the tomb of the dragon, countless dead dragons, their bodies have all turned into white bones, but they maintain the posture of winding and circling before their death, each one, arranged neatly, like soldiers waiting for review.

In addition, there are many variants of dragons, now known as dinosaurs, all of which form a phalanx neatly.

And in the middle of the dragon group, there is a dragon king whose size is far larger than that of ordinary dragons, like a mountain range, stretching for tens of thousands of miles.

There is no longer the slightest fluctuation of divinity in them.

"Dragon's Grave?"

Li Xuan whispered to himself, and there was some inexplicable shock in his heart.

It is conceivable that in some epoch on Earth, there must have been a place for dragons, but they all fell here.

It was the demise of an era.

Li Xuan stayed here for a while, did not disturb their rest, and then his figure flashed, and he came to another door.

Here too, there are graves.

Tomb of the Immortals.

On the empty ground, countless skeletons sat cross-legged, humanoid, and other aliens, gods and demons with four arms, birdmen with wings, and inhumans with twins......

And they have been dead for I don't know how many years.

Perhaps, in a certain era, they were all peerless powerhouses who dominated the party......

……

Next, Li Xuan looked behind more than a dozen other doors according to the places he searched with his divine sense, and all the pictures were the same.

Bones.

There are bones everywhere.

This is the graveyard of every era, every civilization.

Behind a door, Li Xuan even saw a spaceship and countless flying boats, the kind with a great sense of science and technology, which is definitely not comparable to the current technology on the earth.

And...... All the strong people who died here did not die in battle, but were very calm and maintained some kind of wonderful sense of ritual.

It's like ...... Queue up neatly and wait here to die.

Taking a deep breath, Li Xuan retracted his eyes, and many thoughts were circling in his heart.

When the epoch is destroyed, no one can resist that power.

Including yourself.

And this door is more like a museum-like existence, recording the final destination of each era and each civilization.

Li Xuan couldn't help but look up at the ceiling, and in a trance, he faintly felt that there was a higher existence, looking at all this indifferently and ruthlessly.

This door is his collection.

……

……

At this moment, Li Xuan could completely conclude that this door was definitely not something that the Crystal Palace could control.

Even if you are yourself, you can't fully understand everything about this door.

It is not like any magic weapon, there is no so-called "instrument spirit", there are so many graves here, and there is no so-called "tomb keeper". ”

It just stands quietly here, and it makes people feel a kind of shock and awe from the heart.

However, for Li Xuan, the most important question at hand is not what has happened here and who this door belongs to......

Rather—how to get out of here?

The Crystal Palace probably mastered some of the functions of this door, so it was able to borrow it as a portal.

Li Xuan began to retreat.

Retreat all the way to the door where you first entered.

His eyes moved slightly, as if he thought of something, and a little mouse with white hair quietly appeared in Li Xuan's hand.

It was the same Sky Thief that he had gotten on Treasure Island earlier.

Although this Sky Stealing Rat is still in its infancy and its strength is not very strong, its natal supernatural powers are very distinctive.

Li Xuan attached a wisp of divine thought to it, quietly released it, and after squeaking twice, the Sky Thief Mouse ran towards the wall happily.

Bang!

Hitting its head against the hard wall, it suddenly rolled backwards, its feet facing the sky, and its small eyes showed a look of confusion and pain.

This feeling reminded it of when it was imprisoned by Li Xuan before.

I can't wear it at all.

It seems that it doesn't work either, so Li Xuan casually put it away.

This is just a temptation.

Li Xuan could clearly sense that this door was not a condensation of spiritual power and laws, nor was it a forbidden means such as a spatial barrier, but the material was extremely special and could isolate everything.

After a moment of silence, Li Xuan activated the communication magic weapon.

The signal is not blocked.

Gu Xiaoai's confused face appeared on the screen, and Sisi was curled up in her arms, and the two seemed to be asleep.

Seeing Li Xuan and the stone room around him, Gu Xiaoai rubbed his eyes and quickly came to his senses.

"Husband, what's wrong? What's going on? Where are you?"

From Li Xuan's expression and eyes, Gu Xiaoai was keenly aware that it seemed that something was going on, and no one knew Li Xuan better than her.

"You go to find Yue Peng, now take everyone with you, and return to Sky Academy. ”

Li Xuan said in a deep voice.

Hearing this, Gu Xiaoai's eyes froze slightly, she bit her lip a little nervously, and then nodded slightly.

"What about you?"

She asked softly.

Although I don't know what happened to Li Xuan, it is obvious that the situation is not very optimistic, which made Li Xuan make such a decision.

However, during this period of training, Gu Xiaoai has obviously matured a lot, she is not surprised, and when she encounters major events, she also has some calm in her body.

"I'm fine, I need some time, tell Sisi not to worry. If she had to ask, she would say ...... I'm in retreat. ”

"Prepare to go back now, and let me know when you get back. ”

Li Xuan smiled slightly, and had a brief chat with Gu Xiaoai, which was to cut off the communication.

Sitting on the ground casually, Li Xuan took out the ancient god tea table, calmly brewed a pot of tea, and threw a piece of worry-free tea down, and the whole space was filled with an intoxicating fragrance.

Although this situation is a little troublesome, Li Xuan is not panicked.

For him, it was nothing more than being trapped for a while, and in the long experience of cultivation, such things had happened a lot.

This door is obviously an extremely mysterious treasure, and Li Xuan decided to study it carefully.
