It turned out that the Dragon Emperor and the Night Emperor had already rushed to the Cangqing Battlefield and opened up the space for the battle array, and fought a big battle.

However, now, the number of monsters in the hands of the Dragon Emperor has skyrocketed, and the lineup is strong, which can be described as different from what it used to be. On the contrary, because of the incomplete reincarnation relationship, the four kings combined together, can only form the phantom of the Night Emperor for a short time, and the combat power cannot last, so he is defeated by the Dragon Emperor.

The Night Emperor broke through the air, and the Dragon Emperor naturally pursued closely. They were on the same battlefield with Chu Yun, and of course they also discovered Chu Yun and the Bliss Joy Ship for the first time, but both sides had their minds on each other. Chu Yun's small king-level strength did not attract the attention of the two.

Seeing the two emperors shooting away, without taking care of himself, Chu Yun was naturally overjoyed, and hurriedly urged the Bliss Joy Boat to catch up.

He let go of most of his worries, knowing that the two emperors had been competing and entangled for several months, and they had already fought out a real fire, and they had to be defeated to rest. The more they fought like this, the more likely Chu Yun was to sit on the mountain and watch the tiger fight.

The Bliss Joy Ship no longer swayed leisurely, and the lightning shot out, directly smashing through the wreckage of countless warships, and forcibly traversing the entire green battlefield. Then from the place where the two emperors were hidden, he plunged headlong into the thick white clouds.

Chu Yun and the King of Wine both stood on the bow of the ship, waiting for the battle. The Ship of Bliss held up a spherical shield, and the Blissful Immortals hid in the cabin. They are not good at fighting, in case the demon soldiers are broken, it will naturally be Xiang Xiaoyu.

As long as there is a lack of a blissful fairy concubine, it is impossible to form a blissful joy rotation array. Without the Great Array, it would be impossible to create the Innate Yuan Essence, and the value of the Bliss Joy Ship would fall from "one hundred" to "one".

The speed of the two emperors was incredible, Chu Yun reacted immediately, and he had already used his maximum speed, chasing for so long, but he still couldn't see their voices.

All around, there was a vast white cloud mist, as if it was caught in a giant marshmallow, and the clouds were extremely dense, which was a great obstacle to the view.

For a while, Chu Yun's ears heard the whistling sound of the Bliss Joy Ship flying rapidly in the white clouds.

Just when he was worried about whether the two emperors had once again opened up the battle formation space for a duel, the thick white clouds in front of him suddenly dissipated, and a huge city slammed into his eyes.

"This is ......" came so suddenly that the wine king couldn't help but lose his voice.

Castle in the sky!

It didn't take anyone to introduce the answer, and the two kings had this answer in their minds.

It's a huge city.

The Huode City of the Star Kingdom is built on the mountain, and it can be regarded as a male city in the world, but it is not one-third of its size.

The main body of the city is all made of cloud stones. This stone is able to levitate itself without the help of external forces. It is said that in order to build this sky city, almost all the cloud boulders of the entire Star Continent were looted.

Each of the dolomite boulders is milky white, free of blemishes and variegation. Therefore, this city in the sky is also pure white. Whether it is a towering tower, a huge city gate, or a thick city wall, it is all patches of snow white.

If it weren't for the strong color difference brought by the pitch-black base of the city, if others looked at the city in a hurry, they would almost mistakenly think that it was a solid white cloud.

The base of the city is as if the mountain peak has been cut off, and the top is buckled upside down. Therefore, the further down it goes, the sharper it becomes, as if it were a huge black cone, exuding a cold luster in the white clouds, which makes people shudder.

"Such a majestic city with thousands of weather is really worthy of being the first in the world!" After a long time, the wine king broke his silence and exclaimed.

"I thought that Huode City was already a majestic city. Now it seems that there is heaven outside the sky, and there is a city in the city. No, it's not just the majestic spirit, but the city in the sky also has a natural beauty. Floating in the sky, surrounded by white clouds, elegant and noble, like a fairyland. Chu Yun sighed.

Just like the Azure Battlefield, this is also a cloud space framed by the surrounding white clouds.

The soft white light, with plenty of light, makes it very comfortable to look at, and has a good view.

If you really want to compare, this space is a little smaller than the space of the Azure Battlefield. The city in the sky was not in the center of the space, but half exposed, half hidden in the vast white clouds opposite.

From Chu Yun's point of view, the entire Sky City was like a relief embedded in the sky, majestic and magnificent, giving people a poetic touch.

"The Twin Emperors must have entered the city. Let's get in quickly. The speed of the Ship of Bliss suddenly increased, piercing the sky and approaching the Sky City.

The closer we get, the devastation on the surface of the Sky Castle becomes even more apparent. King Chu Yun Jiuhao is a person who has been in battle for a long time, and after observing these sores, his face changed slightly.

The Yunying boulder is one of the toughest in the world, and it is actually broken like this, you can imagine the tragedy of the battle back then.

The gate was split in two, and the ship of bliss and joy gently and skillfully passed through the gap and carried the people into the city.

The scene in the city is not the street houses in the ordinary city, but the urn city. It's a city within a city. It is also a dolomite boulder structure, and it is badly damaged.

Chu Yun didn't want to be happy and happy, so he made it smaller and put it in his arms. And he and the wine king stepped side by side on the stone brick floor of Baiyun City.

"The castle in the sky is a city dedicated to fighting, and it is said that there are ten urn castles in one city, and there are ten urn castles. The center that truly controls the Sky City is the innermost Urn City. Between these urn cities, there are passages built in the sky to connect with each other, and there are also tunnels that are connected under the earth. The whole city in the sky is like a huge labyrinth. Without a topographic map, it's easy to get lost. The drunkard king's face was solemn.

The Two Emperors were still nowhere to be seen, but they knew with their heads that they had entered the Sky City. However, it is indeed very difficult to find them in such an environment.

However, Chu Yun's face was much more relaxed than that of the Wine King: "I have a copy of the topographic map of the Sky City here. ”

He pulls out a drawing, which is a patchwork of two map fragments.

This is what Chu Yun collected when he first debuted and conquered the Star Islands. One of the map fragments was obtained by him from the treasury of Ningjia Island.

"This is something that has been handed down from the craftsmen who built the castle in the sky. Unfortunately, there are still two copies missing, and only four map fragments have been collected to be considered a complete map. The King of Wine glanced at the map in Chu Yun's hand and said.

"It's better to have than nothing. As long as there is a reference, with our wisdom, we can come and go freely here. Chu Yun smiled.

Now that there is no movement in the Sky City, it seems that the Two Emperors have once again opened up the space for the battle formation and are fighting. Chu Yun had no goal, so he had to explore this sky city first.

The city in the sky, shaped like a labyrinth. A long corridor surrounded a long corridor, countless secret passages were connected to each other, Chu Yun and the King of Wine Hao walked for a while, and then they found some clues and rules with reference to the topographic map.

Just as he was getting better, he suddenly killed two demon soldiers from the corner of the corridor.

These two demon soldiers are both wheel-shaped, as big as waterwheels. The surface of the wheel was a hideous, jagged barb of nails, and the demon soldier spun as it whirled, making a piercing whistling sound.

"This is the Demon Guard in the Sky City, the Spinning Wheel. The castle in the sky has fallen, and there are still some spinning wheels left in the city. Seeing the demon soldiers coming, the drunkard king was in danger, so he explained to Chu Yun in a good time.

Although the spinning wheel is violent, it is only the peak level of the spirit demon. Similar to the Flying Battleship, it is a demon soldier with the advantage of mass production.

As soon as Chu Yun slapped the immortal sac, the power of the world suddenly burst out, sucking the two wheels directly into the sac. The vitality in the immortal sac world is very violent, and once the demon soldiers at the peak of the spirit demon enter it, they will be crushed by the vitality.

"Huh, these two wheels can actually support ten breaths in the furious vitality. Chu Yun glanced at the immortal sac and was slightly surprised.

He originally thought that the two spinning wheels would be crushed by the vitality within three breaths. But I didn't expect that as soon as I entered the immortal sac world, these two demon soldiers suddenly deformed for a while, merged into one, and became a big wheel. It took ten breaths to be completely chorenched.

"This kind of refining technique is far beyond the level of Xingzhou. It seems that the rumors are true, and the construction technology of Sky Castle comes from Bingzhou. Among Kyushu, Bingzhou is the most refined. Chu Yun's eyes flashed.

Keep digging deeper.

To the surprise of Chu Yun and the Liquor King, it turned out that the number of demon soldiers remaining in the Sky City was not small.

Half an hour later, they had come across no less than three hundred spinning wheels. In addition to this, there are two kinds of demon soldiers. One is the bamboo sword, and the other is the sword beast.

Each one is a bamboo sword, all shaped like daggers, the sword body is green bamboo color, and it is no more than three inches long. But between bamboo swords, they can be combined with each other. A hundred or so bamboo swords can be combined into a big sword. Gather or scatter, if the ordinary attack breaks up the big sword, these bamboo swords will discard the damaged parts, and the remaining bamboo swords will be re-condensed into a big sword for attack.

If it weren't for king-level masters like Chu Yun and Immortal Bag King, if they changed to the first level of Jun and Hou, they would feel troublesome and annoying in the face of this group of bamboo swords.

The same is true of the Sword Beast. Each sword beast, shaped like a monitor lizard, is a demon soldier war beast composed of crescent-shaped blades. Two crippled sword beasts can merge with each other to form a new combat power.

The most important thing is that the more components, the higher the cultivation of the demon soldiers composed. This kind of weapon refining technique is definitely beyond the level of Xingzhou, and the idea is mysterious and unique, which has aroused great interest from the Feiyang Fairy and other master of army refining.

The Drunkard King and Chu Yun also understood a little why there were still so many demon soldiers left in the Sky City.

Along the way, almost all of them were Chu Yun's shots, and the harvest was also quite rich.

Now in the world of immortal sacs, there is already a sword beast as big as a mountain, a bamboo sword that is dozens of zhang long, and a spinning wheel that is no less than a chaotic demon beast.

These three demon soldiers all have hundreds of thousands of years of demon robbery cultivation. If it is a single component, it will be crushed by the vitality in an instant. But now that they are **, they can compete with the vitality and survive in it for a long time.

Chu Yun told this situation to the wine king, who was also shocked and smacked.

Because this kind of refining technique is no longer a simple superposition of quantity, but a real process that can be added from quantity to achieve qualitative change.

"If the elements are infinite, can it form a peerless demon soldier with a cultivation of millions, tens of millions, or even hundreds of millions of years?" Chu Yun thought for a moment and muttered to himself.

"Of course you can. Whether it is a sword beast, a bamboo sword, or a spinning wheel, as long as there are more components, the higher the cultivation of the combined demon soldiers. However, because of the existence of the Heavenly Tribulation, generally speaking, they only surpassed the peak of the spirit demon. A voice rang out.

"Who is it?"

The wall suddenly flipped, and it was a hidden revolving door. A bronze humanoid puppet walked up to Chu Yun and the Liquor King, and bowed to the two: "Demon Master, I am the guide of the inheritance of Sky City. Only by passing some tests can you become the masters of this city in the sky. ”
