The sun sets, and the sky is darkened.

The glow of the sunset on the west mountain shone on the huge team that stretched for dozens of miles, as if wearing a dazzling dark gold coat.

Seeing the evening, the huge team that kept moving forward slowly stopped.

After all, most of the team is a land trip, and those who can take the flying building and spaceship are only the Xuannu and a very small number of high-level, core or descendant personnel.

Most of the rest of the people naturally need to rest, and it is not convenient to travel at night, and it is easy to have various accidents, anyway, they are not in a hurry, so there is no need to travel at night.

The Feng Department and the Shi Department, which fell at the back of the Xuannu Heavenly Troupe's large team, also slowly stopped, and all kinds of Heavenly Machine Pavilions, tents, etc., swarmed out, all over the place.

"Boom ......"

At this moment, a roar that shook the void suddenly attracted the attention of countless people, and hundreds of people rose to the sky, checking and guarding in time.

A huge steel city with a size of more than 1,000 zhang is suspended in the air, more than 100 meters above the ground.

The whole looks like a steel city rising from the ground. There are 8864 high-rise buildings on it, ranging from 6636 floors to 9981 floors, the whole is divided into eight trigram directions, the highest is the building in the middle, there are 81 floors, and the momentum is like a pillar of heaven standing in the middle of the steel city.

"Hiss......"

"What is this?

"Flying Sky Machine City?!"

"Dahuan Immortal Court's Characteristic Heavenly Machine City?!"

"Why are they all high-rises?"

"It's a city made entirely of steel! how much does it cost?"

"It's a pity...... At first glance, you can tell that it is expensive! However, it is too dense, and it is completely a hornet's nest!"

"What a waste......"

......

Countless gasps arose, and the huge team suddenly swept up countless whispers, as well as countless exclamations, comments, and so on.

No matter what other people think and say, Wu Xin has come to the Hanging Steel City and checked it out carefully!

This is the treasure of the city that Liangzhou Mu Qi Qingshan gave to Wuxin before!

Wu Xin took a cursory look at it, and guessed that this might be a long-distance treasure given to him by Emperor Taiji or a certain Dahuan giant!

Liang Zhoumu alone didn't make such a big deal, mainly because he didn't have such a good relationship or intersection of interests, so that Qi Qingshan could give such a heavy gift!

This is the top-level fusion of the unique scientific and technological civilization of the Great Huan Immortal Court and the mainstream cultivation civilization in the world, bringing together and representing the pinnacle craftsmanship of the two civilizations!

The first is the characteristics of the heavenly machine, that is, the size is as good as it gets, and this alone is expensive!

The second is suspension and flight, which is related to suspension and flight power, which requires ultra-high skills and is naturally expensive.

Then there are a large number of materials, the whole looks like it is purely made of steel, in fact, there are countless materials, such as all kinds of crystal, copper, gold crystal, jade, etc., the raw materials are of immeasurable value!

Then there are various high-tech means integrated into the city, such as lighting, drive, communication, monitoring, attack and defense, etc., which can be described as the culmination of Dahuan technology!

Finally, it is the meson Na Sumeru formation that is integrated into each independent space of the steel city, and the cost is only a lot more than the raw materials and skills!

Roughly estimated by Wuxin......

There are a total of 8864 high-rise buildings, each ranging from 36 to 81 floors, with three to eight rooms on each floor.

Overall, it is estimated that there are forty or fifty thousand rooms in the steel city alone, and each room is carved with the mustard seed Nasumeru formation.

Even if it seems to be the smallest 10-square-meter cottage, there is actually more than 100 square meters of space inside, which is a three-bedroom and two-living room structure, which is enough for as few as three people and as many as dozens or hundreds of people. It's a tenfold expansion, and that's still the minimum spec!

The medium-sized space is the lowest few floors of each high-rise building, and it is a variety of shops or various living facilities, and the space is expanded dozens of times!

The largest space is under each high-rise building, which seems to cover an area of only 1,000 square meters, but in fact it is more than 100,000 square meters, and the 81-story core building in the center and the underground square are as high as hundreds of thousands of square meters, which is enough for the training of 100,000 troops! The space has expanded dozens to 100 times!

All in all, this seemingly a steel city of more than a thousand zhang in size can easily accommodate hundreds of thousands of people, even if it includes more than a million or millions of people, it is completely full.

"Where is this steel city, it's a mobile castle, the strongest troop transport treasure in the world......"

"It's no wonder that the Great Huan Immortal Court can shock the world, not only has it long been the head of the Seven Emperors among the Five Seven Emperors, but it is also recognized as the super country that is most likely to impact the throne......"

"There is no vanity under the fame, and the name is well deserved!"

Wu Xin, who has been on the battlefield for a long time, immediately thought of military use!

You must know that the biggest drawback of the Heavenly Machine Method and the Mustard Seed Na Sumeru Method is that it cannot accommodate living creatures.

To put it simply, if there are living creatures, they cannot be as big as they want.

Therefore, the treasure of heaven is recognized as the top weapon transport in the world. However, there are very few people who really use the treasure of heaven as a weapon to transport weapons, mainly because they cannot be shrunk, and once they are ambushed, they will be wiped out by the whole army. Moreover, the army is not just a puppet, it is a living person with flesh and blood, seven emotions and six desires, and it must also live, and it is impossible to transport it away casually like loading pigs, sheep and livestock, and what morale and combat effectiveness will there be at that time?!

Thinking of this, Wu Xin realized the biggest drawback of this treasure of Dahuan City...... No greenery!

If you look closely, this treasure of the city is completely a steel monster, although all kinds of living facilities are complete, but after all, there is no natural atmosphere, that is, the plant greening factor.

How can there be anything perfect in the world?!

Maybe the Dahuan Immortal Court also has a larger and greenery super city treasure, but obviously it is impossible to give it to the Emperor Wuxin, and the skills required are even more superb!

The most important weapon of the country!

This can be said to be the important weapon of the Great Huan Immortal Court!

......

"Buzz, buzz, buzz......"

After a general understanding, Wu Xin quickly found the core of the city.

The steel city shook in the air, countless buzzing sounds, the aura was permeated, the whole steel city seemed to be alive, brilliant and bright, and there were tens of thousands of rooms, bright and shining, like tens of thousands of lanterns, extremely spectacular, dazzling!

This is the lighting system, power system, monitoring system, communication system, attack and defense system of the unique scientific and technological civilization of Dahuan Immortal Garden, but the energy consumed is a spirit stone!

That is, from Huang Wuxin, in order to understand, understand and control this treasure of Dahuan City so quickly, if it is replaced by others, it will take a long time just to understand!

"Click, click......"

In just over half an hour, more than 100 holes appeared in the base of the city treasure suspended in the air, and ladder ropes and ladders poked out and spread to the ground!

These are obviously the passages in and out of the city's treasures!

Of course, for the strong who can fly away, they can directly enter the air!
