Tianshu Palace.

Xia Yun stood in front of this palace full of books, with a hint of surprise in his eyes, and there was only one thought in his heart, the literati holy land was nothing more than that.

At this moment, he realized that the extraordinaryness of the fairy world was really not something that mortals could imagine.

"You go in. ”

The real moon next to him was not surprised at all about Xia Yun's reaction, not to mention that Xia Yun was just from the Nether Realm, even if the immortal powerhouses of the year were surprised when they saw Tianshu Palace.

"Good. ”

Xia Yun nodded.

"I can walk on my own. ”

Du Yunyun said insistically.

"Hmm. ”

Xia Yun hesitated for a moment, feeling that Du Yunyun's body had recovered slightly, it should be related to the environment here, if it was a place in the four directions, it would take at least a month for her injuries to improve.

After that, Du Yunyun stood by Xia Yun's side.

"Remember, you can only go to the Heavenly Law Pavilion, don't go anywhere else. ”

Matsuki reminded again.

"Yes. ”

Xia Yun nodded seriously, in this kind of place, he didn't dare to mess around too much.

True Moon alone is not something Xia Yun can deal with.

So, Xia Yun took Du Yunyun into the Tianshu Palace and walked towards the Heavenly Law Pavilion.

Zhenyue looked at Xia Yun's back, just smiled slightly, and disappeared.

"Do you really believe her?"

Du Yunyun followed Xia Yun into the Tianshu Palace, leaned in, and asked in a low voice.

Xia Yun shook his head.

"That ......"

Du Yunyun didn't understand a little.

"No way. ”

Xia Yun smiled slightly: "This is fish meat." ”

"Fish?"

Du Yunyun understood in an instant.

They are too weak.

"I think I've seen it here......"

Du Yunyun slowly glanced around, as if swimming in a sea of books, and asked seriously.

"You've seen it?"

Xia Yun stopped and turned his head to look at Du Yunyun.

"Yes. ”

Du Yunyun recalled carefully and said, "At the beginning, the Wind Lord Divine Stone passed by here. ”

"Passing through here?"

Xia Yun frowned.

"Questions?"

Du Yunyun asked suspiciously.

"Yes. ”

Xia Yun nodded and said, "But I haven't figured it out yet." ”

Du Yunyun was silent.

"Let's go to the Heavenly Law Pavilion first. ”

With that, he turned a corner and came into another sea of books.

Du Yunyun immediately followed.

The passage here is different from the understanding of normal people, this is a spatial corridor, and there is no road that can be seen.

At this moment, Xia Yun and Du Yunyun were like walking in the air, but in fact, there was ground, but they couldn't see it.

They can feel the earth beneath their feet.

This sea of books made Xia Yun feel as if he had come to the school from the study.

"These books will move?"

When Du Yunyun saw this sea of books, she couldn't help but be surprised, seeing those books, although there are not many, they are only thousands, but each book is like a person.

"This should be the spirit of the book. ”

Xia Yun guessed.

"You know?"

Du Yunyun suddenly became curious, although she knew that Xia Yun was very powerful, she didn't expect to know about the fairy world.

"Guess. ”

Xia Yun explained: "The true moon is the spirit of the sect, so in the immortal world, there are other spirits. ”

"I see. ”

Du Yunyun suddenly realized.

"Go pick a copy, too. ”

Xia Yun proposed.

"Can I do too?"

Du Yunyun couldn't help but be stunned.

"Matsuki didn't say no. ”

Xia Yun smiled slightly, a little cunning.

"It seems so. ”

Du Yunyun thought about it for a while, along the way, everything that was not allowed, Zhenyue said it, just like Xia Yun could only go to the Heavenly Law Pavilion, which is the current place.

These moving books in front of me are immortal laws.

"Don't force it. ”

With that, Xia Yun walked towards the center of the Heavenly Law Pavilion.

Seeing this, Du Yunyun hesitated for a moment, and then walked in another direction.

She knew that her comprehension was far inferior to Xia Yun, as long as she learned the simple immortal method, she would be very satisfied.

Du Yunyun estimated that the simplest immortal spell should also be stronger than the strongest spell.

Although Xia Yun was a little worried about Du Yunyun, he couldn't be the other party's birdcage.

He believes that Du Yunyun will become a phoenix that travels for nine days.

At least, Du Yunyun has such potential.

"This is the Immortal Law?"

Xia Yun retracted his thoughts, carefully studied the immortal methods one by one, and suddenly became interested, and the things recorded on it were far beyond his cognition.

So, he planned to retreat here for a while.

As for the Wind Lord Divine Stone, he wouldn't worry about anything, with the true moon, it was too difficult for Zhao Junfeng and the others to get it.

Even, Xia Yun has a crazy conjecture, but there is no evidence for the time being, so he can only confirm it slowly.

In the blink of an eye, half a year has passed.

"It's hard!"

Xia Yun suddenly sat on the ground, lay down with his back to the sky, looked at the books floating around, and sighed.

A month ago, he was confident that he should be able to cultivate the Immortal Fa, but after a month, he hadn't even cultivated a little bit of it.

It took him five months to get started, and it turned out to be the same.

At this moment, he finally understood Matsuki's words.

Immortal law is really not something that mortals can cultivate.

"It shouldn't be the reason for the Origin Force. ”

Xia Yun had to think about the reason why he couldn't cultivate again.

Originally, he thought that the immortal law relied on the power of the origin, but the truth had nothing to do with it.

"Why is that?"

Xia Yun frantically calculated, logically speaking, the origin power should have something to do with the immortal law, but he couldn't find out.

"Something is missing. ”

Xia Yun put forward the hypothesis again, and he had thought about it before, but he couldn't find it.

Now, he can only cross the river by feeling the stones.

He believed that Matsuki would not help him.

"Huh, isn't it?!"

Xia Yun suddenly thought of something, and he ignored a key point, the relationship between aura and origin.

The origin power he possessed was given to him by Xiao Hei, not cultivated by him.

In fact, he had studied what the origin power was, but he didn't have a clue at all, after all, the thunder spirit origin he had was equivalent to coming out of thin air.

"Aura, Immortal Aura, Origin Power?"

Xia Yun closed his eyes.

I don't know how time has passed in my cultivation.

Another half a year has passed.

Du Yunyun sighed, only to realize that the immortal method was too profound, and then subconsciously glanced at the direction where Xia Yun was, and found that he was still lying on the ground and did not get up.

Xia Yun has been lying for half a year.

If it weren't for Xia Yun's breath of life, Du Yunyun would have thought he was dead.

At this moment, Xia Yun didn't even breathe, only faint soul fluctuations.

"I wonder if you can use the Heavenly Time Boundary here?"

Du Yunyun was suddenly a little whimsical, in this way, they could use their time to cultivate the immortal method to the limit, after all, she didn't know how long Zhenyue would let them stay here.

"Let's try it first. ”

With a decision, Du Yunyun walked towards Xia Yun.
