If someone asked Lu Chengfeng this question before he was reborn, Lu Chengfeng could only tell the other party, and he himself didn't know. After all, there is a portal to the Cloud Realm on the top of Sky City, which is a rumor that has been passed down since ancient times. Anyway, no one has personally come in, so naturally I am not sure.

But today, Lu Chengfeng can tell him that there really is!

Together with the Liu family sisters, they chased Sean and the others through the last ten floors, and the three of them appeared on the third hundredth floor. The height from the ground here is close to 10,000 meters. Perhaps due to a return to style, this floor is almost identical to the layout of the first floor, except that the top is no longer a 30-meter high ceiling, but a 100-meter vaulted dome.

In the very center, there is also a sloping stone staircase of thousands of steps, which leads directly to the top of the dome.

There is no doubt that this is already the very top floor of the castle in the sky!

When Lu Chengfeng and the Liu family sisters came over, Sean and Lan Fengyue had already stepped on the last dozen or so stone stairs. In just a few seconds, their figures vanished from this level.

The three of them did not stop, and immediately chased after them.

The height of 100 meters did not take too long to pull the three people. When Lu Chengfeng stepped on the last stone staircase and came to the top of the dome, he saw a wider world.

At the foot of the road, there is a super platform with a radius of about 600 meters. At the end of the surrounding area is an invisible enchantment force field, which not only plays a protective role, but also prevents the high-altitude winds and turbulence from harming them. You must know that without this layer of enchantment protection, even a sixth-order master would be able to hold on to an altitude of 10,000 meters for too long. Strong winds, low temperatures, and lack of oxygen, any point is an insurmountable barrier!

As for the zenith, in Lu Chengfeng's imagination, it should be a blue sky. Looking up from the ground, it seems that this is indeed the case. But standing on the top of this sky city, he realized that six or seven hundred meters above his head, there was still a huge world hidden by clouds!

As far as the eye can see, when the wind blows by, you can see a portal looming in the clouds!

That must be the Cloud Realm!

At the first glance of that small world, Lu Chengfeng confirmed its existence. After that surprise, there was an indescribable shock. Who would have thought that at an altitude of 10,000 meters, on the very top of the Sky City, there was such a small world suspended there. What kind of power can make it float in the air and not fall?

Lu Chengfeng can be sure that if it is relying on manpower, even if it is the ancestor of the sword god of the Lu family, he will never be able to do it!

That's right, gravity-free shards!

In his astonishment, a few fragments fell in the shadow of the zenith. Although the thing was quickly blown away in the turbulence, Lu Chengfeng still woke up and realized the mystery of the Cloud Realm being able to float in the air. On the ground, the gravityless fragments that made the core of the flying ship were actually fragments that naturally fell off from the huge cloud realm. With a little treatment, they will regain their original properties and become the most precious special materials!

That's a ......

As for the source of gravityless fragments, Lu Chengfeng had a lot of illusions, but he didn't expect it to be like this!

"That's the Cloud Realm!"

Obviously, not only Lu Chengfeng realized this, but Sean and Lan Fengyue also thought of it. They craned their necks, their eyes wide, and scrambled to look into the clouds, trying to peer into the fabled plane behind the portal. However, it seems that there is a force shrouded in the clouds. No matter how hard they tried, they couldn't see clearly.

"I don't know, can I fly up directly!"

In the face of this miracle of creation, Sean didn't even have the mind to pay attention to Lu Chengfeng. He didn't look back, but looked at the shadow of the zenith with fanatical eyes, muttering to himself.

Lan Fengyue didn't expect that the legend to be true, and his expression was a little more excited and excited. He had already begun to think about how to report to the emperor of the Lanwu Empire when he returned. If you can control this channel to the Cloud Realm, then the Empire will definitely be able to profit a lot from it!

As for whether it will work or not, try it and find out.

Because the invisible force field only protects the top of the Sky City Tower thirty meters high, beyond this height, the power of the enchantment will disappear. What followed was extremely cold temperatures, frenzied high-altitude winds, and a suffocating lack of oxygen. Even if he was an eighth-order mage, Sean didn't dare to test it. With a deep groan, he used his scroll to summon a Tempest Elemental, controlling it to force its flight!

It is impossible for an ordinary flying monster to fly to an altitude of 10,000 meters. Only the elemental creatures of the wind system, who do not need to breathe, are not afraid of low temperatures, and have a particularly light body, can fly to the cloud realm.

Obviously, Sean was prepared for this situation.

Under his control, the cyan wind elemental slowly flew into the air. Within thirty meters of the top of the tower, it did not have any problems moving. However, as soon as he broke free from the protection of the enchantment, the body of the wind elemental seemed to have been hit hard, and like a kite with a broken string, it flew thirty or forty meters away at once, and began to bumble up and down irregularly!

High-altitude turbulence!

Feeling that the wind element was about to get out of control, Sean was startled and hurriedly increased his control over it. Next, although the wind elemental staggered in the turbulence, giving the illusion that it could fall to the ground at any time, it finally flew up with strength under Sean's hard control.

Under the gaze of everyone, the wind element took two minutes to fly halfway with difficulty!

Although controlling the wind element in such a situation requires a great deal of mental power, judging from Sean's face, it should be no problem to support it to the end. But at this moment, a shocking accident happened. A dazzling beam of light flew through the air from the left, instantly piercing the sky. The next moment, the Tempest Elemental was pierced by the pillar of light. Its body, like a torn rag, broke into several pieces, and then dissipated in the turbulence of the wind......

This elemental creature that also has a sixth-order strength in terms of conversion was actually killed in one instant!

"How is that possible?"

Sean let out a loud cry, his face shocked and incredulous.

Seeing that he had already succeeded for the most part, how could his wind elemental be suddenly defeated?

Following the direction of the pillar of light, Lu Chengfeng and the others subconsciously looked to the west. It's just that under the dark clouds and the shadows of the cloud realm, there seems to be nothing. A few people didn't know why, they searched carefully with wide eyes, and after seven or eight seconds, someone shouted with sharp eyes: "Look, there are black spots there!"

When he shouted like this, all the dozen or so people on the top of the tower looked over. At this time, the enemy who launched the attack seemed to be approaching this side, and the target became more and more obvious, and more people were discovering it one after another. As it continued to close the distance, everyone who saw it clearly inhaled in unison.

"Actually...... It's a small island in the sky!"

It's said to be an island, but it doesn't look conspicuous because it's far away. After about two minutes, after the black dot was closer, Lu Chengfeng realized that its area was probably at least half the size of his feet. Not to mention the island, it would not be too much to call it a hanging city. Moreover, there is more than one such hanging city!

In addition to its approach, there are other hanging cities around it, watching this place from afar!

"Look, that giant green eye in the Hanging City!"

I don't know who shouted, which made Lu Chengfeng notice that there were still creatures on that Hanging City - whether the other party could use the word creature to describe it, he was not sure. Assuming that as long as the monsters that can move are living creatures, that's not wrong. It was a pair of large, tapered eyeballs with dark green scales, and a disgusting mucus sheen on the outside. Maybe it was because of the human beings on the top of Sky City, its huge eyeballs twitched up and down, emitting a cold light, which made people shudder.

The pillar of light that had previously fallen the Wind Elemental had shot out from its giant eyes.

"What is this?Is this a watcher of the Cloud Realm?" Sean looked at the giant green eyes, his face very embarrassed, "Why do they want to cut off the communication between the two realms?"

No one knew the answer to this question, but there was one thing that Lu Chengfeng knew very well, if he didn't find a way to kill these giant eyes in the Hanging City, with their threat, it would be impossible for the people of the Mofeng Continent to fly to the six-hundred-meter-high Cloud Realm Portal with a powerful and terrifying pillar of light and high-altitude turbulence.

If this problem is not solved, the so-called portal to the Ink Wind Continent and the Cloud Realm is a joke. Even if they know that people are on top of their heads, they still can't get by!

And, don't forget about so many monsters in the Sky City.

Although this building left over from creation has all kinds of miracles in itself, the monsters inside are still from the cloud realm. However, when the top of Sky City was still six hundred meters away from the Cloud Realm, how did those monsters manage to break through this distance?

Lu Chengfeng wouldn't believe it, they jumped straight down!

There must be a safe passage that will allow those monsters to reach Sky City from the Cloud Realm. Then, these monsters infiltrated from the top of the castle in the sky, layer by layer. Before the magic power mutation and the golden stone gate was closed, these monsters reached the hundredth floor at most, and they could no longer go down. But after the rainy night not long ago, as the golden stone gate burst open, countless monsters poured from the upper floor to the lowest dragonman tower, causing a small disaster, which aroused the vigilance of the Mage Guild.

So, what would that safe passage be?

Lu Chengfeng pondered for a moment, and his gaze fell on the giant eye that was vigilantly monitoring this side in the distance, as well as the hanging city under the green giant eye, through the turbulence visible to the naked eye in the air. The Hanging City, which was incomparably spacious even if it could accommodate a few thousand people, gave him an idea. Perhaps, this empty hanging city is not only a battery for surveillance, but also a transit! This idea was proved only a few minutes later. But what they didn't expect was that there was also great danger with it!
