In front of the thatched house.

Ye Suifeng and Shenwu sat opposite Master Xuan.

Lord Xuan is indeed an old monster who has lived for a million years. The information he knows is simply beyond the reach of a young Immortal Emperor like Shenwu.

Before, Ye Suifeng had always thought that apart from the Wanling Immortal Palace, there was no other force that could truly complete the advancement of the world.

But now it seems that this is not the case.

"As far as I know, in the two major domains of Taiyin and Taiyang, at least two lower realms have become the realm of the Immortal Emperor."

The Xuan Lord said: "The area of ​​an Immortal Emperor Realm is equivalent to one of the ten domains in the Immortal Realm. Controlling an Immortal Emperor Realm is equivalent to completely controlling a large domain."

"As a result, they became the true overlords of the fairy world and extremely powerful."

"As for other major domains, perhaps there have been some successes, but they have been kept secret."

Ye Suifeng was silent for a while.

The Yin and the Sun are indeed ahead of other domains.

No wonder the prophecy says that only in the central area of ​​the fairyland can there be hope of escaping the terrible catastrophe that is sweeping across the fairyland.

"Then do you know how they get promoted?"

"Has it merged with the fairy world, or is it still independent of it?"

Ye Suifeng asked the doubts in his mind.

"Of course it is still outside the fairyland. That is a whole world. How can it be integrated with the fairyland?"

Xuanzhu said.

Ye Suifeng frowned slightly.

According to his discoveries at the Wanling Immortal Palace ruins, the disaster there was caused by the collision between the underworld and the immortal world.

At that time, he thought that there was a great terror hidden in the final stage of the world's ascension.

But now it seems that it has deviated a little.

If you don't choose fusion, maybe there won't be any problem.

Then why did the Wanling Immortal Palace want to pull the lower world over?

Things became confusing again.

"Have you heard of Wanling Xianfu?"

Ye Suifeng asked again.

But this time, Lord Xuan shook his head.

“No.”

Xuanzhu became an emperor millions of years ago, while Wanling Immortal Palace was destroyed millions of years ago.

In addition, he was relatively low-key and lived deep in the Eastern Wilderness, so it was understandable that Lord Xuan had not heard of him.

"Okay, let me ask you one last question."

Ye Suifeng said, "You just said that there are two lower realms in Xuandu that meet the conditions for promotion."

"So, what is this condition you are talking about?"

"Or in other words, what are the similarities between these two underworlds?"

This is also an issue that Ye Suifeng is more concerned about.

There are at least a million lower realms in Xuandu. On what basis do you believe that these two can be promoted? Are other worlds not worthy?

Xuanzhu looked at Shenwu, then smiled and said, "You must know that the selection of the lower world is also determined by the mirror of fate."

"For the immortal world that meets the conditions, a circle of black halo will appear in the mirror of fate."

"Many people know this selection rule."

"But what people don't know is that, in addition to being identified by the Mirror of Destiny, this special underworld all has one thing in common."

Xuanzhu paused, then said: "They all originate from the World Tree."

"This is the conclusion I came to after spending tens of thousands of years examining a large number of netherworlds."

Ye Suifeng was stunned.

The World Tree is a legendary thing.

It was the pillar of heaven that stood between heaven and earth when the heaven and earth were first separated.

It represents all spirits, rules, and everything in the world.

Later, during the ancient war between gods and demons, the World Tree was completely destroyed, turned into fragments, and disappeared into the universe.

The Enlightenment Tree in the Cloud Realm is actually a fragment of the World Tree, so it has the ability to take root in chaos and transform the world.

If what Master Xuan said is correct, all the lower realms that meet the standards originate from the World Tree.

Well, it seems easy to explain.

"From the lower world of the World Tree, it should be easier to ascend, right?"

Ye Suifeng said.

Master Xuan nodded.

"That's right. Moreover, it has the same origin as the World Tree. Its carrying capacity is almost as strong as that of the Immortal Realm. Therefore, there are no shackles. As long as you accumulate enough, you can ascend smoothly."

Ye Suifeng understood.

The Muxian Dynasty foresaw the great catastrophe, so they left behind some means for survival during the catastrophe.

The first is to enter the center of the fairyland, where there is life.

And the second is world advancement.

When the lower world is promoted to the Immortal Emperor Realm, it will be able to communicate with the Immortal Realm. When the catastrophe comes, as long as you hide in it, you can protect your life.

Moreover, the Divine Dynasty also made a special selection to let people focus on the lower realms originating from the World Tree.

Because only in this lower realm is it easiest to succeed in promotion.

It’s not that other ordinary worlds cannot be promoted, but relatively speaking, the time and energy required are too huge.

"Can you get through the two lower realms here?"

Ye Suifeng asked.

Although Lord Xuan had already explained it, he still wanted to go and see what the situation was like there, and what the similarities and differences were with the Yunxiao Realm.

"Can."

The Xuan Lord said: "We have already arranged the passage, and the real body can go to the void space."

"If you want to enter the lower realm, you can only use other methods. You should understand that even the Immortal Realm cannot accommodate our arrival."

Ye Suifeng nodded. He really understood.

"Then let's go down and take a look."

Ye Suifeng said.

"As you wish."

Master Xuan agreed.

Afterwards, the three of them stood up and soon arrived at a carefully designed secret place.

Along the way, Ye Suifeng also witnessed the true power of Xuan Du.

There were six Immortal Emperors they met on the way alone, and there were a large number of Immortal Lords and Quasi-Emperors. They were much more powerful than the Nine Emperors Immortal Palace they encountered in the Eastern Wilderness.

Ye Suifeng originally wanted to take Xiao Hei with him, but after thinking about it, he gave up.

Ordinary Immortal Emperors cannot see Xiao Hei's true nature, but it is hard to say for an old monster like Master Xuan.

If she finds out, there might be some trouble in the future.

Anyway, Ye Suifeng knew everything about Xiao Hei, so it didn't matter whether he brought him along or not.

"Then let's go to the Immortal King Realm first."

Xuanzhu said.

"Can."

Ye Suifeng nodded, and then several people stepped onto a high altar.

With the flash of dazzling light, three figures disappeared from the altar.

When they appeared again, Ye Suifeng found that they had arrived in a black space.

It is the void.

There also stands a tall altar, and around the altar, there are two Immortal Emperors and several Immortal Lords guarding it.

In front of the altar is a whole vast world, quietly suspended in chaos.

Behind the altar is a silvery Milky Way of unknown length.

That is the long river of time in this world.

“The long river of time is quite beautiful.”

Ye Suifeng looked at the Milky Way and nodded.

The master was puzzled and said, "Every world has its own long river of time. You can find it by going to the void space of the lower world."

"Well, maybe."

Ye Suifeng touched his nose.

Shenwu, who was standing aside, had a strange look on his face.

Because he knew that the long river of the world in Yunxiao Realm was broken by Ye Suifeng's punch, and now there was still chaos there.

"Let's go see the World Tree."

Ye Suifeng skipped the topic.
