When the two top powers, the Sky Alliance and the Kafka Empire, began to investigate the matter with all their might, the ins and outs of the matter were quickly clarified.

In fact, they didn't need to check at all, and when the two sides stopped fighting, the Magic Energy Research Institute took the initiative to come to the door!

Everyone in this world knows that there are three giants in the sky today, the Sky Alliance is one of them, the Kafka Empire is one of them, and the last one is the Magic Energy Research Institute.

Among the Big Three, the Sky Alliance is the largest alliance in the world, and the Kafka Empire is the only country today, but the Magic Energy Research Institute is different from either, neither an alliance nor a state, but a purely academic institution.

The headquarters of the Magic Energy Research Institute is located in the Glowing Divine City, one of the ten divine cities, and it is the highest residence in the academic field today, and it has always carried out the top research in various fields.

Any Sky City wants to join the Magic Energy Research Institute, it must let the Institute build a branch in the city, the branch does not interfere with the development of the city, and on the contrary, Sky City must not interfere with the research, and at the same time, Sky City must also provide research funds to the branch to ensure that the research can be carried out smoothly, correspondingly, Sky City can join the Magic Energy Research Institute, not only can get its protection, but also can enjoy the new technology developed by the Institute earlier and more cheaply than other cities.

It is precisely because of the difference in this franchise system that the Magic Energy Research Institute is usually a neutral role, always only obsessed with research, and basically will not participate in such things as fighting for hegemony.

And this time, with the war between the Sky Alliance and the Kafka Empire, a large number of Sky Cities began to join the Magic Energy Research Institute, because when the other two major forces were fighting, only the Magic Energy Research Institute of the same level as them was safe.

Similarly, when the Sky Alliance and Kafka's empire fought, the Magic Energy Research Institute has been paying attention to the movements of the entire world, because since the fall of Tulip City, the research institute has been aware of the demon's abnormality, although it has not taken action but has been secretly paying attention, so this time it was they who first discovered the demon's movement.

Originally, after the Magic Energy Research Institute found out that something was wrong, it planned to contact the Sky Alliance and the Kafka Empire immediately, but I didn't expect that the people sent were still on the way, and the Tulip War Zone was the first to have an accident.

However, this is also a good thing, because any verbal explanation is not as useful as seeing it with your own eyes, and when the Sky Alliance and Kafka's empire felt the changes in the demons firsthand, some things were easier to do.

In this way, not long after the armistice between the two sides, the Sky Alliance, the Kafka Empire, and the Magical Energy Research Institute, the three giants in the sky, gathered in the Nightless God City.

This kind of scene is definitely rare, because there is really no such thing in the world today that deserves the gathering of these three giants at the same time, except now!

A hundred years ago, the demons attacked the land, and people were forced to flee to the sky, and they have survived in the sky until now, and it seems that one of the two sides is in the sky and the other is underground, but in fact it is not.

Perhaps for ordinary people, everyone has long been accustomed to life in the sky, but for those who really control the situation in the sky, the war with the demons has never ended, so there are always people who pay attention to the movements of the demons.

In fact, if it weren't for the fact that the Sky Alliance and Kafka's empire were fighting this time, they might have discovered the anomaly a long time ago.

However, even now it is not too late, when the three major alliances meet in the Nightless God City, the incident quickly comes to light.

According to the investigation of the Magic Energy Research Institute and the information collected by the Shadow Alliance, everyone quickly figured out the ins and outs of the whole incident.

At the end of November of the 118th year of the Sky Era, five small sky cities, Wangui, Spring Rain, Thundering, Matisse, and Jock, were attacked by the Demon Dragon near the Demon Annihilation City, and then the Demon Dragon army surged out of the Demon Annihilation City.

In the next five days, the four small sky cities of Blade Sword City, Juque City, Luminous City, and Jewel City were destroyed by the Demon Dragon.

These nine small sky cities were the first cities to be destroyed by the demon dragon, after which the demon dragon disappeared for a while, but it didn't take long for it to make a comeback, attacking the two medium-sized sky cities of Linhai and Feixiang, followed by the large sky city Yandi City.

At this time, both the Magic Energy Research Institute and the Shadow Alliance had noticed this matter, and urgently sent people to investigate, and soon investigated all this clearly, and then came to a terrible conclusion, that is, the controller of the Demon Slayer City, the hundred-headed dragon Typhon, was born!

Typhon, one of the Thirty-Three Demons, also has a theory that he is the head of the Thirty-Three Demons, in short, an extremely terrible demon, even among the Thirty-Three Demons.

This guy is a huge evil dragon, nearly a thousand meters long, and has a hundred heads, almost invincible in the sky, and what is even more terrifying is that this guy can also command all the demon dragons in the demon.

At the beginning, the city lord of Spring Rain City asked Kuni to investigate the history of Demon Annihilation City, but Kuni came to the conclusion that the history of Demon Annihilation City had disappeared, but of course this was not the case, the history of Demon Annihilation City did not disappear, but was hidden, and the hidden reason was Typhon!

In real history, as the first city to be conquered, Demon Slayer City quickly became a gathering place for demons, which is the same as the legend, there is only one difference, that is, after the city was captured, it belonged to Typhon, and it has been his territory for a hundred years, and it is precisely because of this that Demon Slayer City has always been listed as a forbidden area.

And according to the investigation of the Shadow Alliance and the Magic Energy Research Institute, the Demon Dragon successively destroyed and did more Sky City, which was done by Typhon, and this terrifying existence suddenly ran out of Demon Annihilation City for some reason.

It's a terrible result, no, it's terrible.

Because ordinary people may not know the Thirty-Three Demons, but the real rulers in the sky know how terrible these demons are, when the demons attacked the land, and can really occupy the land and the Thirty-three Demons have an inseparable relationship, they are like the leaders of the demons, leading the demons to conquer the city and the earth, forcing people to the sky step by step.

So it's no exaggeration to say that these thirty-three demons are the real threat to this world, compared to them, ordinary demons and high-level demons are simply good babies, if these guys have any action, it will be a disaster for the whole world!
