I, the Male Protagonist of the X Series

Back in the separate office arranged for him, Rin wiped off the cold sweat from the doorman, loosened his tie, sat down on the chair, and sighed.

"As expected of Lily Academy, are all the students so bold? Hey, the X world I live in is really peaceful."

He took out a bottle of fruit juice, took two sips, when someone knocked on the door, and after a while, he stared at Huihui, who was out of place in a magic hat and a magic short robe, poked his head out.

"Hui Hui, what's the matter?"

"Teacher, I have some doubts about theoretical knowledge and want to ask the teacher."

"Oh, please sit down."

Reaching out to signal Megumin to sit down, Rin pushed his glasses, ready to enter teaching mode.

Huihui, who was holding her palms tightly and lowering her head, raised her head to look at Rin from time to time, hesitated for a long time, and then mustered up the courage to ask: "Dare to ask the teacher, in the second step of explosion magic, using the magic element ratio formula, How to calculate the superimposed cumulative limit damage?"

"..."

Hey, what the fuck is your physics teacher not a magic teacher, do all of you reincarnators have brain problems?

It's a good thing I know magic knowledge, otherwise I'd be stumped by you.

Lin kept silent, folded his palms and placed them on the table, his glasses slid over the light of wisdom, and said calmly: "Huihui, the explosion magic you asked about is actually a knowledge point for magic students below the third grade. I should use the more advanced Qiyao magic to explain, if the fire element is π, Φ is the gold element, Δ is the sun... that is, the light element, then the damage limit function should be... blah blah blah."

"Finally, use the magic array to create a ninth-order magic square, and use the 3 by 3 sub-matrix as the matching ratio. Then, the answer is clear at a glance. The resulting limit damage is far higher than that of the third-level explosion magic, and it is easier to calculate."

Huihui stared blankly at the full drawings in front of her, stood up abruptly, put away the drawings, and bowed seriously to Rin, her eyes full of firmness: "Thank you teacher! From today onwards, I recognize you !"

"..."

"Then, don't bother the teacher anymore, I hope you will teach me in the future."

After finishing speaking, her eyes were full of ΥΦρ and well wood, water, fire, earth, sun and moon symbols, and Megumin, who was in a state of magic research, left Rin's office step by step.

Rin glanced at the closed door inexplicably, and calmly picked up the juice and continued to drink.

Fortunately, he is not the kind of protagonist who knows how to have sex without doing anything. He has learned some magic knowledge when he is bored, and his world level is relatively high, so his knowledge is wider than Hui Hui. Teacher Zhang Renmin lost all his old face, and Huiyin had to die.

Hey, I have nothing to do in the afternoon, so I just go back to the apartment and continue to toss about the Lord God Space Store.

Determined, Rin opened the desk and stuffed useless books and textbooks into it, and then opened the other desks to find that they were empty, which did not fit his status as a dignified special teacher at all.

Touching his chin, Rin exchanged a few powerful-looking books from the main god's space. Because it was just for pretending, he didn't look at the names at all, so he closed the cabinet directly.

Well, in addition to knowledge, money is also the main element to experience a person's identity and self-cultivation. It is too out to put money directly...

So he directly grabbed a few gems and stuffed them into the cabinet, followed by pistols and magic tools, OK to call it a day and leave.

Chapter 540 Is Your Elder Scholar Emiya Scholar?

Rin never thought that he could still be treated like the male lead of light novels, for example... On the way home, he met a little loli standing at the door of his house, blinking and staring at him.

This little loli has beautiful long silver hair, a purple aristocratic blouse and a cute little skirt, and a pair of watery red eyes are pure and flawless staring at him.

Hey, a little girl who looks like a snow elf... What can I do wrong, but I want to be a reincarnation...

Hey, how could someone who has played fate not know him, this one is undoubtedly Illya.

Glancing secretly at the familiar wristwatch on the silver-haired little loli, Rin paused, thought for a while, and then took a few steps forward and walked up to the little girl.

"That, little sister."

"elder brother!"

"……Forehead."

Illya raised her head, stared at Rin with bright eyes, then handed a letter to Rin with a blushing face, her eyelashes fluttering so cutely.

Rin subconsciously reached out to take the letter, glanced at the cover, was shocked, took two steps back, his face was almost as black as his hair.

I saw the big characters "Jingu Kana" written on the lower row.

This is completely impossible woc!

As for the agreed game world, why is there a letter from his mother? !

Rin, who was expressionless on his face, quickly opened the letter and looked at the contents. The letter was not his mother's notes, but the final seal was indeed real.

The general content is, knowing that Rin will return to China to experience teaching and educating people, and send her condolences and blessings. By the way, she will mention that the daughter of her good friend in a foreign country will return to China to go to school for various reasons, and please ask him to take care of it for a while.

And this child's sister is called Ilyasviel von Einzbern.

The letter was quite formulaic, not like the tone of the real Jingu Kana at all, Rin closed the letter, thought for a while, and figured out the current situation.

His identity is an NPC arranged into this world, so as an NPC, he must have parents and family members, so it is normal to have a fictional Jingu Kana.

In the same way, the reincarnated person is also assigned an identity in this world, so it happened to be linked with Rin's identity, and then he received the letter from Jingu Kana.

So... Do you still have to take care of the little loli? It's so troublesome!

Fortunately, the admission procedures have been completed to avoid a lot of trouble, tsk, and it is fun to be able to observe the world up close without being played by various strategies, hahaha.

Holding back his complacency, Rin touched Illya's head kindly, and said in a warm voice: "Then, just live with me during this time, and I will definitely take good care of you!"

"Well, I'll be taking care of brother Rin from now on, Illya is very good."

After taking Illya's backpack, Rin opened the password door and welcomed Illya in. As soon as she opened the door, Siri rushed over with the "(*^▽^*)" emoticon board. The look of the stick made him feel distressed.

Illya was shocked... I don't know if it's true or not, but she showed a big jump, hiding behind Rin, and looked at Siri curiously.
