Su Nuan opened the library in this Heavenly Palace, and there were some jade books in it, most of which were ordinary things, a little exercises, and some biographies, these books were left by the previous realm lord.

Those exercises are not true immortal exercises, but exercises practiced by monks below the immortal level, but they are also somewhat subtle.

Picked up a biography and read it.

It records the various experiences of the realm lord in a place other than the mirror heaven, and there is also a detailed description of this divine tree domain.

Through the records in the biography, we know that this so-called Spiegel Sky is actually a world, which is very huge, and hundreds of millions of living beings live, including human races and rare birds and beasts.

And the so-called Divine Tree Domain, is a huge sacred tree, which is very ancient, the legend is that since the existence of the fairy world, this sacred tree has existed in this world, on which thousands of flowers bloom, each flower, is a world.

The Spiegel Heaven that Su Nuan is in charge of is just the most inconspicuous flower in the Divine Tree Domain, and there are tens of thousands of worlds like Spiegel Heaven in the Divine Tree Domain.

And in every flower world, there is a realm lord of the immortal realm, so there are at least 10,000 immortals in this divine tree domain.

When Su Nuan saw this, she was shocked in her heart, she, the realm master, was just the most ordinary immortal identity, and there was nothing special.

And the immortals of the Divine Tree Domain, the true status of the Blue Emperor Immortal Palace, are all in the Immortal Palace at the top of the Divine Tree Domain, and they will not go down to such a flower world to do this kind of boring and not very profitable realm lord position.

Read on.

After about two hours, Su Nuan read all the records here, and had a second understanding of this Divine Tree Domain, but he didn't fully understand it yet, the previous Realm Lord, who was also an Outer Gate Elder like her, couldn't understand the deeper things of the Immortal Palace.

Su Nuan put down the jade slip in her hand, she sat down cross-legged, and waited quietly.

And so, three days passed.

On this day, in Su Nuan's mind, who was meditating, there were voices coming from far, far away, her expression moved slightly, and then she calmed down and went to communicate with the voice.

In the realm of ten thousand laws.

A huge sacrifice was being held in the Tianwai Mountain, and countless statues of the gods emitted divine light, and the power of faith scattered in them turned into thousands of light filaments, which were absorbed by the altar.

The altar was in operation, and many supernatural characters appeared on its surface, which was communicating with Su Nuan in the upper realm.

Wu Yi Ancestor looked at the direction of the altar intently, and couldn't relax in his heart, when Su Nuan was ascending, he had told him that she should use this altar on the fifth day after her ascension, so as to test whether this altar was really useful.

Now, it's time to put it to the test.

Suddenly, a divine thought came from the altar.

This divine thought was transmitted to the minds of the monks present, and they were all overjoyed when they heard clearly what was conveyed in the divine thought.

Then, above the altar, a white light suddenly appeared.

A small object fell from the white light, and the sacrificial float on top of the altar, it was a leaf, with the breath of otherworldly on it.

Wu Yi Ancestor's eyes lit up, he cast a spell to grab the leaf in his hand, and he used a spell to seal the leaf to prevent the aura inside from dissipating.

"Sure enough, it's a fairy thing. ”

The other side.

Su Nuan sent the leaf to the Nether, and also heard the voice received from the Nether, she breathed a sigh of relief, she had already tested that this altar was really useful, and could even teleport some small objects down.

And such small objects are really small, and they can't teleport living things, let alone use them to the lower realm.

"There's something else!"

Su Nuan saw that there was a strange power in his body, that power was very pure, it was the power formed by the sacrifice, when he teleported that leaf just now, this power was consumed, and there was still some left in his body.

I investigated with my divine thoughts, but I didn't find anything, so I had to give up, and I just waited for the opportunity in the future to try it again.

Open the map in the Spiegel Heavenly Palace, in the map, is the whole map that the puppets have just drawn, it is a three-dimensional image, and there is a point of light in it, and the place marked by the point of light is where she is now.

The whole picture of this Heavenly Palace is very huge, comparable to a city, and there are guards in many places, who are the servants of those who are waiting for the immortals of the Heavenly Palace.

In this immortal world, everyone has immortal roots and has the qualifications to cultivate.

The immortal root is like the spiritual root, Su Nuan washed the body in the immortal pool, and the spiritual root in the body has turned into a fairy root, only the immortal root can better absorb the immortal energy, and the spiritual root tree in the cave has also become a fairy root tree, and only the immortal energy is born, and it is no longer the spiritual energy.

In the territory under the rule of the Blue Emperor Immortal Palace, there are also many mortals living in it, although those mortals have immortal roots, most of them have no cultivation methods and cannot step into the immortal path.

And once every ten years, the Immortal Palace will go down to the mortal realm and select some people with good qualifications to become servant disciples in the Immortal Palace.

The real disciples of the Immortal Palace are all one in a hundred thousand of top geniuses, born to open up the immortal cave in the body, such geniuses, born with miraculous visions, when they are born, they all have visions.

Only those who are born with supernatural wonders can attract the attention of the Asgard Palace and become a disciple in the Asgard Palace.

As for the other ordinary people, even if their qualifications are not bad, they can only start as servants, and the identity of this servant is also the identity they want to ask for.

It is only because of becoming a disciple of the Immortal Palace, or a servant, that you have the opportunity to obtain the cultivation of immortals, and set foot in the immortal path, as long as you can attract qi into the body, you can greatly increase your longevity.

The fairy palace is very strict with the mortals of the mortal realm, one of which is to restrict mortals from privately obtaining the immortal cultivation method, and there is no immortal cultivation method on the market.

And mortals in the fairy world, if they don't practice, they will also have a lifespan, and if they live for about 10,000 years, they will almost reach the end of their lives.

Although 10,000 years seems to be a long time, if it takes tens of thousands of years, you can only be an ordinary person, which is also an unwilling thing for most ordinary people in the fairy world.

The wind of cultivating immortals is prevalent here, and people in the world want to seek immortality, and many people are taught by their elders all kinds of beauty in becoming immortals as soon as they are born.

However, the Immortal Palace will never allow it, there are so many cultivators, only those who have been given the cultivation qualification by the Immortal Palace are qualified to cultivate, as for why the Immortal Palace is so strict, Yan Lingxue and other servant palace maids have no right to understand.

Many years ago, there was a turmoil in this mirror sky, which is said to have been caused by the cultivation of immortal exercises, and later an immortal came here to stop the turmoil and took away the exercises.
