I killed someone.

Even though there was no blood on my hands, I did kill her.

It was a heavy fact that knocked me awake. This was the other world which was no longer a peaceful country where my hometown was located.

Walking out of the prison, I looked at my master walking in front of me. Thinking back to the memories she had just shown me, there was nothing better to say than cruelty.

At the same time, I wondered if freedom has become a luxury.

I desperately wanted to understand this world, since I couldn’t go back to Earth, and I didn’t want to live in this world with confusion.

To understand this world, the first was to ask people, and the second was to read books. It was inappropriate for me to ask people. Maybe it was proper for me to read books. But where was the library of the castle?

The master seemed to have read my mind. She paused for a moment and turned her head.

"If you want to understand the world you can go to my room. There are books for you to read."

Would I go into the master's room again? But was my status suitable to enter the master's room? I have the impression that slaves usually live in humble houses, at the disposal of their masters, and cannot enter their masters' rooms without permission. But as a slave, I was served by a maid in this world?!?

The master did not answer my doubts, so I had to follow her back to the castle.

---------- ----------

After returning to the master's palace, the master called Lindsay and Daisy.

Lindsay and Daisy pushed open the door to the master's room and walked in, I followed the master with a little nervous.

"Lindsay and Daisy, you guys stay with her here and read."

"Yes."

The master turned around and looked at me with her usual serious expression.

"You can ask them if you don't understand anything."

She walked out of the room after I nodded slowly. Fortunately, it wasn't the master watching me in the room, or I would have been too nervous to read the book.

There are many kinds of books in the bookshelf, but it's not a mess, it's divided according to categories.

I scanned the types of books in the master's bookshelf.

There are four bookshelves, including military arts, politics, historical accounts, and various books.

The master doesn't look like a tyrant at all when you look at the types of books in the bookshelves.

Shaking my head, I looked for historical accounts to read.

In this world, there are only two advanced species, the human race and the demon race.

The physical quality of the demon race is stronger than that of the human race. Besides, the magic talent of the demon race is also much higher than that of humans, so the demon race constantly harasses the human countries by this advantage.

A long time ago, there were still many small divided countries in the human world. And the devil race has always believed in the power. The idea about obeying the strongest one in the demon world makes the demons more united than humans, At the beginning there was only one Demon Kingdom.

But it was because of the constant invasion of the demons that made these countries in the human world have to unite together against the demons.

According to their respective physical quality, a demon can probably fight against ten humans.

If a demon releases the magic, he can probably fight against 20 humans.

Demons live longer. There was a demon over 300 years old according to the historical record. but a normal demon should only live to more than 200 years. And most of the human life expectancy is below 80 years. But their reproductive capacity is stronger than that of humans, so the human population is much larger than that of the demon.

At the same time, the magic power stored in the body of the demons is larger than that of humans, and the magic released is more stronger than that of humans.

Initially, humans could only use many soldiers to try their best to fight against the demons.

More than a thousand years ago it was the birth of the first generation, Ilotia, and this experiment was only known to insiders.

With the Ilotia, the demon army was even more invincible. For a time, Ilotia almost took over the human capital.

In order to fight against Ilotia, all the best forgers and magicians in the human kingdom gathered together and spent a lot of financial and material resources creating a sword called Flame Demon Killer, too juvenile. But since the Gut took this sword, his strength could be almost as powerful as that of Ilotia.

Then what was the legendary figure of the Gut? The Gut only accepted one disciple. After the Gut died, his power would be passed on to his disciple, and his disciple would inherit the position of the Gut.

But this Gut was indeed bizarre. It was said that the first Gut was just born gifted, eloquent, and never had gray hair in his life.

Back to Ilotia, her life expectancy was unknown. The first generation of Ilotia existed from 1200 to 500 years ago. It was said that the the first generation of Ilotia was a cool and emotionless machine in her soul according to the historical record, but that generation of Ilotia never revealed the story of her previous life.

Looking at the description in the history books, the first generation of Ilotia disliked going out, talked less. She didn’t communicate with people basically, in short, may suffer autism. But this generation of Ilotia committed suicide after spending 700 years of solitude.

I imagined that if the soul in the first generation of Ilotia was just a human with normal life span , and she knew that her life span was longer than anyone else, probably in order not to see her close people die of old age one by one, she blocked her own emotions.

The second generation of Ilotia was not as indifferent as the first generation of Ilotia, but a homicidal maniac who was a homicidal maniac in her previous life, killing for fun, and reincarnated into Ilotia, which matched with her soul perfectly.

The second generation of Ilotia led her own troops into battle, and she brought Ilotia's abilities into full play. Therefore, the human cities she occupied flowed with blood. Suddenly the girl who slaughtered the city flashed in my mind, as if she was killing with a sense of pleasure.

So since from the second generation of Ilotia, the hatred of humans for the demons reached an unprecedented level.

But three hundred years ago the second generation of Ilotia was destroyed, and the reason for the destruction was unknown.

Then why such a powerful demon race launched so many invasion wars but could not completely capture the human kingdom successfully?

The first was the existence of the Gut, and the second was that the demons have made no attempt to make progress, that is, the demons have always revered the strength, and aggressive. They never put humans in the eye, so two words can describe them, barbarism and arrogance, so that the of civilization of the demons gradually lags behind the human race.

This can be referred to the Qing Empire, which was closed to the world.

Humans are the ones who take their advantages against the demons, and used their wisdom to overcome the demons' barbarism.

So, more than two hundred years ago, the last Demon King, who was also the parent of the master, realized this problem and took the initiative to learn from the human kingdom, which was the legendary reform.

At the beginning, the reform was resisted by many demons, but many of them saw the effect and then there was no opposition.

Although the civilization of the demons can not catch up with that of the humans, the reforem also made the Magic Kingdom become strong again.

Seeing here the master came back, I’ve only skimmed it, remembered the general content. I don't know much about those reforms, the system of the Magic Kingdom, the state of the country or anything.

But I have not asked Lindsay and Daisy about any questions and asked them to stand all the time, which made them a little tired. Thanks to their accompanying I can feel at ease in the master’s room.
