In order to avoid the war in the sky, the five small sky cities of Wangui, Spring Rain, Thunder, Matisse, and Jock united together and hid in the airspace where the Demon Annihilation City was located.

Demon Slayer.

One of the forbidden areas in the sky, originally this was a city, the earliest name of which has been forgotten, but it is rumored that this city was once a huge and prosperous city during the Land Era, with a population of tens of millions.

A city of this scale is no longer seen in today's world, because even the population of the Ten Great Divine Cities is only about one million, and it cannot reach the level of ten million at all.

But perhaps because the city was too prosperous, after the end of the Battle of the Extinction, the demon crossed the battlefield of the Extinction and began to officially launch a full-scale attack on the land, and the Demon Slayer City bore the brunt of the attack.

Attacking a city of tens of millions of people should have been a huge war, but it wasn't.

In the early days of the demon's attack, Sky City and the Sky Demon Battle Armor had not yet been invented, and people simply did not have the capital to fight against the demons, so the Demon Annihilation City was captured in a very short period of time, millions of troops were ruthlessly killed by the demons in the war, and tens of millions of residents died after the fall of the city.

And today, nearly a hundred years later, this place is still a gathering point for demons, there are countless ordinary demons in it, and the number of high-level demons is extremely large, making this a forbidden area, whether it is land or airspace, it is forbidden for any Sky City to enter.

But today, with the war in the sky, the little city lords who are forced to be helpless can only hide in Tibet, compared to the same kind of people who are eyeing each other, the small city lords who have no ability to protect themselves would rather gamble with the devil.

Wangui, Spring Rain, Thundering, Matisse, and Jock are the five small sky cities that are like this, they are united and hide together in the airspace where the Demon Slayer City is located.

Of course, they also had self-knowledge, knowing that with their strength, even if the five Sky Cities were united, there would be no way to risk in the forbidden area, so although the five city lords let Sky City enter the airspace of Demon Annihilation City, they only stayed on the periphery and definitely didn't dare to go deep into it.

............

One day in November of the 118th year of the Sky Era, Maximilian, the lord of Spring Rain City, was looking at the latest information sent by the Shadow Alliance, and as in the past few months, all the content of the information was related to war, and the protagonists of it were naturally the Sky Alliance and Kafka's empire.

"Hey......"

Looking at the all-round coverage of the war on the intelligence, Maximi let out a long sigh, and then threw the information in his hand aside.

When exactly will the war end?

After reading the content of the intelligence, there was only this one question left in his mind, the current situation is obviously that the immortals are fighting and the people are suffering, if the Sky Alliance and the Kafka Empire continue to fight like this, for three or five years, how can these small city lords live!

Just as Maximilan's face was full of sadness, there was a knock on the door of the study.

"My lord, Mr. Cooney is here. ”

"Oh, please come in. ”

Hearing the guard's announcement, Maximilian hurriedly stood up and immediately straightened his clothes, obviously preparing to welcome a very respectable guest.

Soon after, an old man of about seventy years old was taken into the study.

"Lord of the Castle. ”

The old man was very old, his hair was gray, and he didn't look very good, he looked like he was in old age, and he nodded weakly after being taken to the study.

But in the face of such an inconspicuous old man, Maximilian immediately stepped forward and helped him to his seat, and then sat opposite him and asked:

"Mr. Cooney, have you found out about the Demon Slayer City?"

Although this old man named Kuni looks very ordinary, he is actually just an ordinary person, but he is the most well-known scholar in the entire Spring Rain City, especially for the study of history is very professional and comprehensive, and he has always been very respected in the city.

And Maximi, the city lord, happens to be a very careful, or very suspicious person, so this time, although he hid in the airspace of Demon Annihilation City with several other Sky Cities, he has always been uneasy about Demon Annihilation City.

It's no wonder that he is like this, because there are many rumors about Demon Slayer City, but they are too vague, why this city has become a forbidden area, and what kind of specific danger it has, these things are not mentioned in the rumors, which makes Maximilian very worried, but unfortunately, as the city lord of a small sky city, he is completely incapable of touching these things.

If it was in normal times, as a small city lord, he would never let his Sky City come to such a dangerous place in his life, but now it is different, now his Spring Rain City is in the airspace of Demon Annihilation City, he must figure out what kind of danger is here, so as to prepare in advance, so he asked Kuni to find detailed information about this forbidden area.

"Lord of the Castle ......"

Glancing at Maximi, Cooney gasped for a while before he spoke slowly, only to hear him say in a weak voice: "I'm really ashamed, the old man is only a shallow learner, and I haven't found much information about Demon Slayer City, and some of the records found are the same as rumors, saying that this place has always been a gathering place for demons, and there are many high-level demons, so it has become a forbidden area." ”

As he spoke, Cooney shook his head, saying that he hadn't discovered much.

Although Kuni is proficient in history, his identity is just an ordinary scholar, although he is indeed very knowledgeable, but because his identity is too ordinary, there are some things that he can't touch at all, and it is precisely in the hundred years of history of the demon's attack on the land that many things have disappeared for various reasons, and these disappeared histories are either man-made or lost, in short, there are many historical materials that cannot be found.

But after that, he said, "But my lord, I have found some records about this place in the wild history, and I may be able to help my lord." ”

"Tell me about it. ”

"My lord, I saw such a record in the wild history, saying that when the Demon Slayer City was first attacked, the demon dispatched a terrifying demon dragon. ”

"Demon Dragon?"

Hearing this, Maximilian frowned, could it be that there is a demon dragon in the Demon Slayer City?

However, just as his brow furrowed, Cooney continued: "My lord, there is more to this wild history than that......

"Oh? What else?"

Glancing at Cooney, Maximi hurriedly asked.

"According to records, when the demon dragon attacked the demon annihilation city, it just sat up, and the one above the demon dragon was the truly terrifying existence......
