I'm a monster in Demon King's Castle

Li Yue found it difficult to teach Mini and Mini to read in a short time, so he only superficially projected a few words like "human" and "monster" into their minds, and asked them to pay more attention to numbers, thereby simply drawing a range, and then let them go to find it.

"How about this book? There are numbers! 259! And ten?" Mini and Mini began to rummage through various books in the library hall, and each time they found one, they stretched out their arms and sent it to Li Yue, asking if it was suitable.

The other Minis were noisy and running around on the ground, so the behavior of Li Yue's two Minis was not abrupt, but quite natural.

Li Yue himself also constantly released his perception, constantly searching in the two piles of books around him.

Refocusing his mind, Li Yue read the full name of the book — "The Top Ten Mercenary Groups of the Kai Calendar 259".

"Mercenary group? Not bad, okay, put it in!" Li Yue signaled Mini and Mini to let go, and included "The Top Ten Mercenary Groups of the Kai Calendar 259" into the pile of books, and at the same time raised a question — what major event happened in the Kai Calendar 259? Why compile the list of nobles of this year, and also select the top ten mercenary groups?

Could it be a period when human power reached its peak? So you want to keep the brilliance?

While Li Yue was thinking, Mini and Mini, who had been praised, became more energetic.

"This one has 'human'! It must be okay!" This time Mini jumped up and shouted, bringing over a copy of "Human Anatomy".

"And this one! This one also has the word 'human', but it doesn't seem to be the same?" Mini's little hand trembled, showing a hint of doubt.

Li Yue looked at the "Dwarf Enchanting Craft" in front of him, and couldn't bear to dampen Mini's enthusiasm: "Dwarves... can also be considered humans, put it here first!"

Then Li Yue used his mind to press "Dwarf Enchanting Craft" under the pile of books...

In this way, soon Li Yue, with the help of Mini and Mini, roughly "cleaned" the pile of books next to his desk, and found more than a dozen books related to the human history of the Chaos Continent, and even harvested two precious books that made Li Yue's mind twitch.

Human history can be put aside and studied slowly, Li Yue is currently very interested in the other two precious books about monsters, and can't wait to read them immediately.

One is called "Monster Rating", written by a bishop of the church. It classifies existing monsters according to their strength and danger level, which is very helpful for Li Yue to understand the monsters themselves.

The second is "Introduction to the Demon Expeditionary Army", which was originally stuffed in the pile of books. It was written by the Minister of War of the Tas Empire and his team. It detailed the existence and dangers of the Demon Expeditionary Army, and summarized its actions, becoming a textbook for various fiefs of the Tas Empire to guard against Demon King City...

The Demon Expeditionary Army, isn't that the force that forced Ougibugey to retreat? Budi Boge just mentioned it, and it is closely related to the brain spirit...

After thinking for a moment, Li Yue directly used his mind to open "Monster Rating", and started to understand the most basic monster knowledge.

As soon as Li Yue turned the book, Mini and Mini were stunned.

"What are you doing? Working?" Mini and Mini noticed Li Yue's strangeness and ran over happily, "Is this what the book says... the textile women's association will take the initiative to compete?"

Involution? No, no, no, this is a struggle for life — Li Yue slandered in his heart, and raised his head to face the two little sweet potatoes.

"This book seems good, I'll take a look first, you guys look for it, don't worry about me." Li Yue transmitted his thoughts.

"Take care of your body..." Mini muttered, turned his head and continued to flip through the books, but he was even more enthusiastic in his search.

It's rolled up... Li Yue sighed and refocused his attention on "Monster Rating".

Neither moonlight nor candlelight was very bright, but this had no effect on the brain spirit — Li Yue finished reading the short "Monster Rating" in one breath in the flickering light and the busyness of Mini and Mini.

The rating divides monsters into eight levels, irregularly corresponding to the ten combat levels of humans, and adds some rhetoric such as "for reference" and "to be supplemented", leaving some room for discussion.

Although this classification is not absolute, it also gives Li Yue a general understanding of the combat power of this world — monsters are divided into four major levels, namely monsters, demons, quasi-demon kings, and demon kings; the classification of monsters and demons is derived from the three stages of low, medium, and high, plus the two levels of quasi-demon kings and demon kings, which add up to eight ratings.

The core idea of judging the rating... is the degree of harm that different monsters cause to human society. Among them, monsters below the high level have the ability to cause small-scale harm to humans. After being promoted to the demon level, they will be rated as "harming the city" and must be eliminated as soon as possible...

Li Yue read this and defaulted that the brain spirit should be a type of low-level monster — because this type of monster is indeed not strong in terms of destructive power alone and cannot affect the human mind, so the degree of damage is only limited to a "small range".

And the monster wolf Fendis in the arena and the gladiator with the three-headed giant dog... should be demon level? There is a possibility of "harming the city"...

Then didn't I kill them by leaps and bounds?

Li Yue nodded secretly, thinking that he didn't embarrass the transmigrator, even if he only transmigrated into a low-level monster.

Thinking, Li Yue couldn't help but guess the level of Ougibugey — is this guy a high-level demon? Or a quasi-demon king level?

After all, it is an existence that enjoys a golden name and birth record in the Demon Illustrated Book... Even if it is not a quasi-demon king level, it may not be far from it, right?

In the description of quasi-demon king level and demon king level in "Monster Rating", it is written that quasi-demon king level has the ability to destroy a country, and demon king level may even lead to the extinction of mankind, which is shocking.

Li Yue thought of the arena, in front of the throne, that brief meeting with the Demon King... He suddenly felt that this world was larger than he imagined. This gap does not seem to be filled by one or one hundred supreme magic stones.

Recalling the scene where the Demon King flicked his fingers and the entire audience returned to silence, Li Yue felt that he might have to keep a low profile in the near future and not disturb some existences at the top.

Compared with monsters, there are also some general introductions about the strong among humans in "Monster Rating" — the ranks of human strongmen are diverse, including magicians, knights, hunters, etc. Through magic potions and their own training, they may reach incredible power...

Different ranks have their own advancement paths, but the overall strength still has a general division of first to ninth ranks, such as the ninth-rank knight, the seventh-rank magician...

Purely from the perspective of combat power, the first six ranks of warriors are about the same as the sixth rank of demons and monsters, but once they cross the seventh rank, that is, the quasi-demon king level, it is difficult to predict the outcome simply by comparing strength. Specific situations should be analyzed specifically.

After the ninth rank, the strong among humans will enter a new stage — archmages, holy knights, hunter kings... all of them are the best among humans, and will become existences guarding one side, far from being provoked by monsters or demon-level monsters.

Of course, as a monster, Li Yue still has some remnants of memories about human strongmen, and found that the brain spirit only collectively refers to them as "warriors". It is estimated that it is the same among Mini and Mini, which is a general summary of human strongmen by monsters.

On the first night after the third full moon of the Kai Calendar 299, Li Yue, who had finished reading "Monster Rating", had a clearer understanding of his position in this world, knowing that the road is long and arduous, and only regretted that the bishop did not specify how monsters break through levels, otherwise it would be enough for Li Yue to use it as a secret book.

Raising his head, Mini and Mini at the same table were still busy, constantly throwing one book after another into this pile of books; most of the remaining Minis had already fallen asleep, and no one cared that there were still three "overtime" monsters in the hall.

Casting his mind on the magic hourglass on the table, Li Yue realized that it had already lost one-third of its time. There were still five or six hours left in the night, enough to finish reading the remaining "Introduction to the Demon Expeditionary Army".

Using his mind to massage his stiff brain grooves, Li Yue refocused his attention, preparing to read the story of the Demon Expeditionary Army, so as to speculate on the near future, as a brain spirit, in what posture will he... intersect with the Demon Expeditionary Army?

Perhaps everything in the library right now is related to the Demon Expeditionary Army?
