The people in power have been secretive about the existence of the Thirty-Three Great Demons, and even hid their history, so that ordinary people don't know about their existence at all.

Because these existences are so terrible that once they are known to the general public, they will only bring panic.

Fortunately, although each of the thirty-three demons is extremely threatening and terrifying, they are not the true leaders of the demons.

In that great war a hundred years ago, the thirty-three demons did lead the demons to conquer the land, but after that, no, it should be said that in the process of conquering the land, these big demons gradually stopped participating in the war.

For example, the hundred-headed dragon Typhon, he stayed in the city after leading the demon dragon to capture the demon city, not only did he no longer command the demon dragon, but also did not participate in the subsequent war, and the other great demons were basically in this situation, it felt as if their practice of leading the demon to conquer the land was completely based on interest, and when they were interested, they would fight a dozen of them, and if they were not interested, they would not care.

This situation was the case from the middle of the war to the end of the war for a hundred years, especially in the hundred years after the end of the war, the thirty-three demons seemed to disappear, and basically did not appear much.

For this phenomenon, people have not been able to figure out the reason, and they can't understand it at all, but this performance of the great demons is extremely beneficial to human beings, because without the leadership of the great demons, although ordinary demons and high-level demons are still very terrifying, but after all, they are scattered, and people are still capable of resisting them.

It's just that what everyone never expected, after disappearing for a hundred years, Typhon, one of the great demons, actually appeared again, and once it appeared, he commanded the demon dragon to destroy more than ten sky cities, which is not only surprising, but also not a good phenomenon!

So after finding out about this matter, the Magic Energy Research Institute, which didn't want to pay attention to the war between the Sky Alliance and the Kafka Empire, couldn't sit still, and immediately prepared to send someone to contact both sides, but before the people sent by the Magic Energy Research Institute could leave, the warring parties were the first to be attacked by demons.

I have to say that this attack came at a very good time, because on the one hand, this attack saved a lot of effort for the Magic Energy Research Institute, and on the other hand, it also brought new information!

Demons can fly!

This matter is even more important than Typhon!

The Magic Energy Research Institute had only found the Demon Dragon and Typhon before, and it didn't know that there were also types of demons that could fly into the sky, so this can be said to be extremely important information, and it is even more terrifying.

Because no matter how powerful Typhon is, he can only lead the demon dragon, and the number of demon dragons as high-level demons is limited after all, but if you add ordinary demons, then the severity of this matter will rise to another level.

In this case, as the three giants gathered in the City of the Nightless God and put all the information they found or encountered on the table, a terrible result appeared.

Demon......

It's time to take action against the sky!

Such a result is actually not difficult to guess, because it is easy to judge as long as the series of actions of the demon is combined, and if you look back, you will find that the changes about the demon in recent years have actually been uninterrupted.

A few years ago, two years ago to be exact, Tulip City had not yet fallen, and the three holy cities were still standing on the ground, but at that time, there was a strange incident when the demons suddenly attacked the three holy cities at the same time.

A year ago, the fall of Tulip City shocked the whole world, and the world may not know, but those who know the truth know that there was a demon dragon when Tulip City fell.

And now, with the appearance of Typhon, one of the great demons, and the appearance of the flying type among the ordinary demons, everything that has happened in the past few years has been connected together, and the demons are ready to do something to the sky!

Is that so?

Be!

The judgment of the Big Three in this matter was extremely accurate, the demon was indeed planning to do something to the sky, no, it should be said that it had already done so......

Because just when the three major forces gathered together to discuss this matter, many Sky Cities were attacked by demons to varying degrees.

It was not the demon dragons led by Typhon who attacked these Sky Cities, but the more terrifying ordinary demons.

Why are ordinary demons scary?

Because ordinary demons are the most numerous of all demons, the individual strength of these monsters may not be as good as that of high-level demons, and they are not comparable to the great demons, but they are too numerous, which is true on land, and it is also true after coming to the sky.

The attacked Sky City has all encountered a large number of demons, and these demons have flown from the land to the sky without warning, both in number and variety, far beyond people's expectations.

According to the statistics after the fact, some Sky Cities encountered thousands of demon attacks, some encountered tens of thousands, and the most unlucky Sky City simply encountered tens of thousands of demons, so that even Sky City was surrounded by groups, and the city was almost destroyed in the hands of these demons.

What's more, there are more types of flying demons, although there are a lot of flying demons encountered in the Tulip War Zone, there is only one, a dark red, flesh-winged demon, but these Sky Cities that were attacked later encountered are not only this kind of demons.

Among the other demons encountered in Sky City, there were dark red flesh-winged demons like the Tulip War Zone, there were also demons that had never been seen at all, like gargoyles, this kind of demon flew in the air as if it were a big stone, and even a demon that looked like a small demon dragon, although this demon was only five or six meters long, it could spit fireballs from its mouth like a real demon dragon, and both battleships and air demon warriors had a headache when facing this kind of demon.

In short, after statistics, people found that there were as many as six or seven types of flying demons, and this was only what people had seen, and it was not known how many they had not seen.

And all of this means that things are going in the worst direction, and in this case, the people in the sky are immediately plunged into fear and chaos!

There was no way, when the demons began to appear in the sky on a large scale and constantly attacked Sky City, it was impossible for things to be covered up, and then spread uncontrollably, sweeping the entire sky in a short period of time.

In this case, everyone knows that action must be taken, or the sky will be over.

But who in the sky has the power to act?

Naturally, it was the Sky Alliance, the Kafka Empire, and the Magic Energy Research Institute, so for a while, everyone's eyes were focused on these three forces, all waiting for their actions.
