The huge building complex in the distance looms in the mist, like a stretching mountain, the main structure of the entire building complex is very large, and these towering buildings imply mystery, arranged in a peculiar way, it is likely to be a formation, but Rao has studied the formation for so long, Xiao Han is still very difficult to calculate.

The layout of these buildings resembles a sealing circle, is this a seal?

Xiao Han guessed in his heart, how much time would it take to build these buildings?

The buildings stretch for thousands of kilometers, each hundreds of meters high. The history of NPCs is simulated by the Flood Server, that is, the building was built little by little. It would have been impossible to build such a large complex without thousands of years.

Moreover, this suspended city is built under the Taixu Immortal Realm, and there is a bottomless abyss below, which increases the difficulty of construction, and it is absolutely impossible to complete it with the strength of a few saints alone, and it must have used a lot of manpower and material resources.

For such a big matter, why is it not recorded in the Ghost Venerable's notes, or even mentioned at all? It's a little weird, too.

It stands to reason that if there is really a powerful person or creature sealed in this hanging city, and the aura emitted is very evil, even more terrible than Shiva, assuming that this person is from the evil path, why don't the saints of the evil path stop it when the righteous saints are building this building?

Xiao Han guessed that this sealed person or creature was likely to be the common enemy of the Evil Path Saint and the Righteous Path Saint, and this building was probably built by the Evil Path Saint and the Righteous Path Saint.

Moreover, this person or creature frightened the Evil Path Saint and the Righteous Path Saint, so they unanimously chose to remain silent and not mention this issue again, and the Ghost Venerable's notes also deliberately concealed that period of history. During the period between 10,000 years and 20,000 years, it is very likely that something terrible happened, and about 10,000 years was probably used to build this hanging city.

Also, what prompted the saints to open up the Six Realms. What about the other hanging city that Fluttershy and Mai Aya encounter? Many questions swirled in Xiao Han's heart, which aroused Xiao Han's curiosity, and Xiao Han wanted to explore this period of history.

However, it is clear that Xiao Han will not open the seal here indiscriminately, and he inadvertently released Shiva, making the entire human world a mess, and almost harming some NPCs he knows, this lesson makes Xiao Han remember it vividly, Xiao Han is afraid that he will release a person or monster that is even more terrible than Shiva.

Xiao Han walked towards the Hanging City, the magnificent building made Xiao Han breathtaking, and he didn't know how much manpower and material resources were spent to build it to such a scale as it is now.

A faint smoke shrouded the Hanging City, setting off the entire Hanging City like a dream, such a building should only exist in a dream.

Walking through the long stone bridge, which was no different from a single-plank bridge, Xiao Han came to the city gate of the suspended city, the city gate was closed, and the entire city gate did not know what metal it was made of, the whole body was jet black, solid and heavy.

Walking near the iron gate of the Hanging City, Xiao Han felt a majestic aura of energy suppressed, this is the energy enchantment that Fluttershy and Mai Aya are talking about, and no one or creature above the king level elite can enter this Hanging City. Fortunately, he is at the bottleneck of being promoted from the king level to the king level, and he can just enter here.

Why does the Hanging City have this energy barrier? This energy enchantment does not have any breath of life, and it should be released by the magic circle. So it should have been arranged by the saints, probably to prevent anyone from entering the Hanging City?

But in this case, Xiao Han's heart has another question, how did the Skyware Demon Dragon enter the Hanging City that Fluttershy and Maiya discovered? The Heavenly Demon Dragon is a beast-level pet, so why is it not affected by the energy barrier?

There are too many questions, and the secrets of the year still need to be revealed little by little. The next time I go back to the human world, I'll ask the old man what happened at the beginning. Although he was a saint of the Later Jin Dynasty and did not participate in the history of the period from 10,000 years to 20,000 years of Taixu, after all, he had been with the rest of the saints for so long, so he must know something.

Xiao Han couldn't help but guess again, the saints opened up the Six Realms, and the Six Realms revolved around the Taixu Immortal Realm, and the Taixu Immortal Realm and the Human Realm each found a suspended city, so could the other five realms also have a suspended city?

What is the purpose of the saints in opening up the Six Realms, could it be that it is to build a suspended city?

Why can't I figure out the formation of the Hanging City? Xiao Han suddenly thought of something, his heart was shocked, and he looked towards the Hanging City, although the location of the buildings in the Hanging City has changed in a thousand ways, it is generally in line with the arrangement of the Big Dipper in the sky.

The Big Dipper, the Seven Realms, the Seven Hanging Cities, Xiao Han thought of a legendary formation, the Nine Heavens and Ten Earths Seven Stars Demon Sealing Array. This formation is the most complex formation ever made, and it is recorded on the last page of the "Seven Books of Formation Diagrams", and no one has ever laid it out. The description of this legendary formation on the "Seven Books of Formation Diagrams" is only a few words, and Xiao Han still remembers that passage clearly.

This formation cannot be arranged unless it is the time of the Nine Heavens of Ice and Snow, the Ten Earths of Flame, and the Seven Stars. When arranged, the project is huge, with a total of 7749 formations, each of which needs to be infused with supreme mana, driven by the blood of the saint, and guarded by the spirit of the saint before it can operate.

Such a formation cannot be completed by one or two saints, and the last page of the "Seven Books of Formation Diagrams" draws a specific formation diagram. At the beginning, there were people who specialized in the study of formations, and they worked hard to calculate this formation, but the more they calculated, the more complicated they found this formation. In the end, we had to resort to the greatest invention of mankind - the computer. He used a state-of-the-art home computer to perform the calculations, and the computer eventually got into a state of confusion during the calculations and had to stop the research.

Even the computer can't calculate this formation, so you can imagine how much effort the designer spent when designing this formation.

Xiao Han remembered that there were some strange narratives behind the "Seven Books of Array Diagrams".

The red moon shattered, the void collapsed, and the great earthquake cracked. Bury the head in Tianshu, bury the right hand in Tianxuan, bury the left hand in Tianji, bury the body in Tianquan, bury the soul in Yuheng, bury the right foot in Kaiyang, bury the left foot in the shaking light, nine days of ice and snow, ten earths of scorching, seven stars in a row, 50,000 years of broken bones, 100,000 years of soul extinction.

These words are very strange, usually, Xiao Han didn't care, although he felt that this text was very strange, but it didn't seem to have any special meaning, so he ignored it, but now that he thinks about it, he feels that this text is very wrong.

Xiao Han savored this text carefully, what does the red moon shatter, the collapse of the void, and the crack of the great earthquake refer to? Disaster?

In the following texts, Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Shaoguang are the seven stars of the Big Dipper in the sky, the seven stars, the seven worlds, and the seven hanging cities, is there some special connection between these three?

'Bury your head in Tianshu, your right hand in Tianxuan, your left hand in Tianji, your body in Tianquan, your soul in Yuheng, your right foot in Kaiyang, and your left foot in Shaoguang. What exactly is it trying to say? Could it be that there are seven seals that seal a person's head, right hand, left hand, body, soul, right foot, and left foot?

Nine days of ice and snow, ten scorching places, and seven stars. This is a necessary condition for the arrangement of the formation, but it has no special meaning. As for the 50,000 years of broken bones and 100,000 years of soul extinction in the future? Does it mean that it takes 50,000 years to seal him to crush his bones, and seal 100,000 years to wipe out his soul?

The more Xiao Han thought about it, the more he felt that his guess was correct, because in this way, he could explain the origin of the Hanging City.

Who the hell is this person, as for letting so many saints go to great lengths to open up the Six Realms, build a Hanging City, and seal all parts of his body and soul in the Taixu Immortal Realm and the Six Realms? If that's the case, then this sealed person is also terrible. Xiao Han really had a hard time imagining his strength.

Due to the opening of the Six Realms and the construction of the Hanging City, Xiao Han guessed that the saints had also worked together at the beginning, but they didn't know what contradictions had happened, so that there was a clear distinction between the righteous saints and the evil saints. In the ghost venerable note, 10,000 years ago, everyone devoted themselves to cultivation, worked hard to become saints, helped each other, and never had any fights, and there was no ambition and ** at that time. The ghost honored the situation with great nostalgia and longing.

Later, why did the righteous saint and the evil saint become incompatible enemies?

How much happened during the period between the 10,000 years of the Taixu and the 20,000 years of the Taixu? Because this period of history is too long, there is no clue, there are many clues and stories that are incoherent, and it seems that someone still needs to explain or find more clues.

Xiao Han glanced up at the dark iron gate, the cold iron gate was closed, what kind of history was hidden in this iron gate?
