"In fact, below grade A, there is no clear boundary for this grade, in fact, it is a little confusing, the so-called C grade is upper, middle and lower, but there is only a vague concept, maybe a certain time everyone thinks that this person is very strong, everyone classifies him as a superior, but in fact he is likely to be only intermediate or even subordinate, and even he may not even be a C grade, so the rating below A grade is not credible. ”

Uncle Lu Yi had never taught these things, so Lu Yi was curious: "What about the A level or above?"

"Going from B to A is a watershed. The headmaster said, "You should know that all the monsters have turned into human forms now, and some of them are even born in human form, and they don't know what their true appearance is until they die of old age." ”

The headmaster gestured with a fan and said, "The monster changes into a human form, and from a biological point of view, it is actually a complete metamorphosis. ”

How can this thing be explained by so-called science? Lu Yi will be skeptical and listen to it.

The principal also knew that this was difficult to accept, and said patiently: "In this case, this development process is theoretically irreversible. But youkai can spend a lot of money to break this theory, all youkai have a chance to change back into the form of a youkai after turning into a human form, but at least the price is a greatly shortened lifespan, and some even die outright. ”

Lu Yi's heart beat faster when he listened to these unbelievable things, and asked, "What does this have to do with the division of ranks?"

The corners of the principal's mouth curled slightly, and he said with a bitter smile: "Because the difference between A-level monsters and B-level and below is that after they change from human appearance to monsters, they can still change back, although the price is still expensive." ”

Lu Yi was puzzled and asked: "That being the case, I don't really understand why the monster still has to become a human being, so that the combat effectiveness will be greatly reduced, and the gains outweigh the losses." ”

The headmaster stretched out his wrinkled hand and said, "First, after the youkai turns into a human form, the lifespan will be greatly increased, and it will not be a problem to live past a hundred years......; Can you accept a wolf, a tree, a skeleton having sex with you?"

"No, you can't. Lu Yi replied without thinking about it, but then realized the meaning of the principal's words, and his heart moved slightly.

"So. The headmaster put down his hand and said, "For the sake of racial integration, they must change if they don't want to." ”

"Nope. Lu Yi retorted slightly: "I don't quite agree with you when you say this, I admit that youkai may have paid a lot for racial integration, but you must know that the extension of lifespan is very tempting, and under the trade-off of pros and cons, I don't think there will be many youkai who will resist this." ”

The principal shook his head, nodded again, and didn't go to debate with Lu Yi, but continued: "Therefore, the advantage of A-level monsters is that they have a hole card that can save their lives, and compared with A-level monsters and below, this advantage can be infinitely magnified. ”

After listening to the principal's explanation, Lu Yi frowned, and asked hesitantly, "That...... What about the S-class?"

......

......

"S-class youkai...... the headmaster sighed softly, "That's a completely unruly existence."

"The strength of S-class monsters is originally unattainable compared to other monsters, but the reason why S-class is superior to other levels of monsters is that they have basically broken the boundary between humans and monsters, although they will still cause serious damage to themselves when they completely change from human form to their original form, but ...... They have a very unreasonable ability, they are able to perform part of the physical transformation. ”

Lu Yi listened and asked, "Partial transformation?" can you explain in detail?"

When the principal heard this, he really explained to Lu Yi: "It's literal, changing part of the body from a human to a monster, and the cost is very small, just like two people are fighting and fisting, and the fist of the other person suddenly turns into a sharp wolf claw, or a stream of fire erupts from his mouth, this advantage is overwhelming compared to other monsters." ”

Lu Yi was a little shocked, and a little puzzled, according to this explanation, the monster turning into a human form is equivalent to exchanging a powerful power for a longer lifespan, but the A-level monster can have a chance to use that power at a high price, while the S-level monster uses the original power at a very low price, but the cost is minimal.

Lu Yi reluctantly accepted this fact and asked, "Then, can this still be explained by biology?"

The headmaster smiled but didn't answer.

Lu Yi was helpless, so he had to ask another question: "So, what do you mean by telling me this?"

"I told you that uncle did me a favor. ”

"Yes. ”

"He's been teaching you for so many years, and I can probably know what he's taught you, and he's not teaching you what he's talking about today, but you should know that this is your first class at the Silver Cross Academy. ”

Lu Yi scratched the back of his head, like a person who had an idea but didn't dare to speak to the teacher, very embarrassed.

The principal squinted his eyes at Lu Yi and said, "If you have something to say, just say it." ”

"Then I'll say it. Lu Yi sat down and said seriously: "I'm weak." ”

The principal looked at Lu Yi, his expression was still kind, but he was not angry, and said: "You are not weak, although the level evaluation on the human side has always been very complicated, and there is no standard that is too accurate, but in my opinion, A-level, you deserve it." ”

"No, no. Lu Yi shook his head and said, "I can't afford it, I can't afford it." ”

"Deserve it. The headmaster said in a deep voice, faintly with an unquestionable meaning.

Lu Yi still said: "Even if you force me with an A-level title, others will not recognize it." ”

"I set the standard for this youkai level. When the principal heard this, he opened his mouth and laughed silently: "So no one will question it." ”

It's not that you won't, but you don't dare. Lu Yi broke out in a cold sweat behind his back and said, "Actually, my relationship with my uncle is not very good, so ...... I can't represent what Uncle meant. ”

The fan shaking in the principal's hand froze slightly, surprised that Lu Yi had actually analyzed something by himself from these words, and immediately smiled: "You don't have to represent anyone's will, you can represent yourself." ”

"I'm not as important as you think. ”

"A grade, no matter where you put it, it's important. ”

Lu Yi couldn't help but tremble a little nervously, his fists were so white that his knuckles turned white, and he gritted his teeth and said, "Can I think about it?"

The principal's expression was still the same, and he nodded and smiled, "Yes." ”

......

......

Amy had a dream in which she dreamed that she had come to a vast basement that was dimly lit but full of bookshelves full of fragments of books she had seen in the Tiangong bookstore.

Amy was excited at first, then quickly calmed down, thinking about what had happened recently, thinking about the possibility of this scene in front of her, and she finally regretfully came up with an answer: it can't be.

Amy approached the bookshelf, took a book and opened it, and sure enough, she had read all the contents herself.

It was a dream.

It's not strange that Amy is still awake in a dream, or she's already familiar with this feeling, she found out about it soon after she became sensible, and at first she thought it was something like the world in the magic book, but then she was disappointed to find out that it was just a dream.

Amy flipped through the already familiar contents of the book in disappointment, the reason why she was able to read so many books at such a young age had a lot to do with her dreams, everything she had read could be reviewed in her dreams, but after so many years, she was tired of it now.

Amy had an idea, and as soon as she stretched out her hand, a book flew out of the countless shelves and landed in her hand.

"I actually said that I don't know how to be polite. Amy opened Mencius in her hand and looked at it at a glance.

......

......

"Miss Amy, Miss Amy. ”

Amy heard someone whispering her name in her sleep, so she opened her eyes in a daze, clenched her right hand into a fist and rubbed her hazy eyes, and saw Lu Yi standing on the edge of the sofa, muttering half-asleep: "Slow down, what has that old man been talking to you for so long." ”

Lu Yi looked at the cute girl in front of him who was rubbing her sleepy eyes, and kept glancing at her.

"Huh?" Amy gradually came to her senses, and saw an old man with a kind face and a young man wearing a hood standing behind Lu Yi.

The old man was holding an iron pestle, his body was a little rickety, and he looked ordinary at first glance, but no matter how ordinary he looked, he couldn't hide the old man's temperament that had been in the top position for a long time.

Amy reacted immediately, jumped off the sofa, bowed to the old man in a proper manner, and said, "Hello Grandpa, the principal." ”

The principal smiled gently, wrinkled slightly, and didn't care about Amy's previous impoliteness, but liked her current title very much, and smiled: "Little girl, a gentleman should be the same on the outside." ”

Amy raised her head, looked up at the principal, puffed out her cheeks and said, "Only women and villains are difficult to raise, and besides, I am in cardamom, and I am a child." ”

Lu Yizheng was worried that Amy's words would make the principal unhappy, but he didn't expect the principal to laugh after hearing it, and he was not unhappy at all.

The principal stretched out his wrinkled left hand, gently rubbed Amy's little head, and then took a metal object from Zhou Tai's hand behind him and handed it to Amy: "It's hard to come from the inner courtyard, so this should be given to you by grandpa." ”

Amy was flattered and didn't know whether to take it or not, so she looked at Lu Yi pitifully, as if asking for his opinion.

Before Lu Yi could speak, the principal stuffed the thing between the things into Amy's small palm and said, "There is a library on the top floor of the Heavenly Palace that is the largest in the academy, although there are no remnants of the books in that store, but the collection of books is much more than the books in your dormitory building, this is the key." ”

Amy was overjoyed when she heard this, and hurriedly put the key into her arms, and her mouth also called sweeter: "Thank you, grandpa." ”

The principal touched his beard and said with a smile: "Okay, you should still have something, so don't delay too much." ”

"Yes, yes, Principal, goodbye. Lu Yi pulled Amy to the door and bowed slightly.

"Goodbye, grandpa. Amy smiled and clutched the key to her chest like a little girl protecting her favorite toy.

Amy thought for a moment, bowed again, and called out sweetly, "Goodbye, sister." ”
