AS calendar year 955: The 6th demonic calamity broke out.

These are records regarding the demonic calamities.

There are only a few records remaining from over 500 years ago, there are many cases where we don"t know the exact dates.

Also, there are some which are just vague oral traditions.

There are some which are said to be written down by the following generations.

If we doubted these, there wouldn"t be any end.

We"re speculating that these are probably the truth based on their chronology.

"Do you have any questions so far?"

Today is history cla.s.s.

The one in charge, Albright-sensei asked.

"The 1st demonic calamity isn"t there though?"

Jamie raised her hand and spoke.

Albright-sensei smiled bitterly to Jamie, who spoke before she was called on.

"There aren"t any records. But in the existing records, we know most of what happened in the demonic calamity that happened in AS calendar year 200, or the 2nd demonic calamity. Thus, it must have happened before then, but there are no remaining records or traditions about it."

Things recorded in history——history that has been recorded and written down with words.

They"ve been made for about 1000 years in this world.

There are no earlier records.

However, this definition is dubious.

In this world, there was unmistakably an ancient empire.

A civilization that had far more developed magical science technology.

The Ancient Ulugu Empire.

It"s impossible for that empire to not have had characters.

It"s just that we"ve never found any.

Well then, I wonder if that era doesn"t fit into those recorded in history.

If we find their characters, it might be that we just have to add them though.

Even in my former world, the years we"d learn in history cla.s.s would change after a while.

That historical person never existed, they were just made up!

After all, they existed.

Such skit comedy-like things like that happened too.

While listening to his explanation, I absentmindedly thought about such things.

Meanwhile, Albright-sensei"s explanation continued.

There are almost no records from before 1000 years ago, and humanity"s range of activities weren"t very large.

At first, humanity lived in the mountains to the east.

"Why did they live in the mountains? The mountains are more inconvenient than the plains right?"

Tiraiza asked what she thought was suspicious.

In my previous world, civilizations appeared near large rivers.

It seems natural that on the plains by the river is the most suitable.

"The river would be convenient for everything. If they lived there, then humanity may have developed faster, but there are demons in this world."

Albright-sensei thoroughly explained.

"That time"s construction techniques were still not very good. It was easier to fight the enemy in the mountains rather than by the rivers."

Of course, there are many demons who can fly through the sky.

However, rather than meeting the enemy in the plains, taking advantage of the mountains and meeting them in fortress is unmistakably better.

Even if they emerge from the plains, they can run away from the Maou into the mountains.

Humanity lived like that during the early years of the AS calendar.

With the progress of various technologies humanity"s population increased, and just living in the mountains became too cramped.

As if driven out from the plains, the people who lived in the plains increased.

As their castle construction and combat techniques improved and they became capable of defeating an average Maou in the plains, humanity surged into the plains.

That was a period of development for humanity.

"Now, the majority of people live in Briton, Island, and Scottyard, which have a lot of plains. There are some plains in the south, but since we know that the Maou appears there, few people live there."

As if he remembered something, Albright-sensei stood still.

"That reminds me, recently an interesting paper was published. Apparently it"s an investigation into the Maou"s strength."

Those words seemed to be more like he was speaking to himself.

It"s slightly off from the cla.s.s" contents.

"Is it the one where the next Maou becomes stronger if you defeat it too quickly?"

Yufilia asked.

"Yeah. That"s very interesting. Certainly, that might be possible as a trend. Of course, there isn"t enough data so we can"t say anything though."

There"s only a handful of people who study history in this world.

Collecting records and data isn"t something simple.

Well, they"re properly written down in my diary though.

"If that ends up being right, then it"d be another something I"m guilty of then……"

Yufilia made an uneasy expression.

That"s because it was Yufilia"s party that defeated the previous Maou Marc.o.k.

"The fact that the previous Maou was pretty weak spread around at an early stage. There wasn"t an end to the ones who wanted to defeat it in pursuit of honor. Yufilia-kun, even if you didn"t defeat it, some other hero would have."

Since the Maou was weak, humanity"s pace was disordered.

Despite the Maou being weak, as a result not just a little damage occurred.

It was an ironic result.

As the damage increased, the major powers moved, and instantly defeated the Maou.

In the end, the one that ended up a step ahead was the Briton Kingdom.

For Briton, the fame of Maou-killing was something they wanted by all means.

The hero who defeated the Maou 3 years ago was also a soldier from Briton, and that formed the base of Briton"s dignity.

"That"s why you guys shouldn"t worry about it. If possible, I want to meet that professor and listen to his story though."

At the end adding his thoughts, Albright-sensei concluded the lesson.

His hopes probably won"t come true.

I thought that in my heart.
