Intermediate 21st Class Teacher's Office.

Lu Tianyu looked at the door of the head teacher's office with blue letters on a white background, and felt a little different from what he remembered. He remembered that when he came here with his aunt that day, it didn't seem like that's what he saw. But what was different, he really couldn't remember.

He wanted to find Gaidu to solve the previous misunderstanding after class, and asked her about the academy's flea market by the way, but unexpectedly, the head teacher finished talking about the subject of the envoy demon, and asked him to come to the office with her.

"Did you see this sign last time you came and thought it was different?" said the head teacher, who walked in front of him with a book in his arms, and opened the door.

Lu Tianyu was startled, she still had eyes behind her, and she knew what she was thinking?

In fact, the teacher noticed through the blurred reflection of the door, and he paid special attention to those words. After entering the office, she put the book on the table, then sat down and said, "You are very observant, and the door number is white and blue when you see it again, and I only changed it to blue on white a few days ago." ”

I see! Lu Tianyu said: "No wonder I always feel something different." ”

"You really deserve to be Lu Tianji's child, and your observation and grasp of things are very good. No wonder the flower chain recommended you to be the captain. ”

"Lu Tianji......" Lu Tianyu heard this name for the first time, and asked a little excitedly, "That's my father's name?"

"Hmm. The head teacher was stunned, "You don't even know what your father's name is, do you?"

Lu Tianyu shook his head: "I don't remember." My sister never told me about my parents. ”

In his memory, his sister told his parents that after they had an accident on the plane, they never mentioned half of their parents. Once, when he asked about his parents, she scolded him. He was also told not to ask anything about his parents in the future, saying that it was better for him not to know. At the time, he didn't know why, but now that he thinks about it, it turns out that his sister is trying to protect him.

"Your dad is a great guy. The head teacher said with emotion, "When it comes to your father, no one knows about it, no one knows it, and among the younger generation of magicians, it can be said that no one is outstanding, and he is regarded as a "genius magician". It is said that when your father was eighteen years old, he created a magic that shocked the wizarding world at the time. It's a pity that after your father met your mother, for some reason, he suddenly announced that he would no longer be a magician, and both withdrew from the magic world and lived an ordinary life. After that, they were never heard from again, and even your aunt did not know their whereabouts.

"Your aunt has been searching for you until two years ago, when she unexpectedly learned that your family had gone to another world. Unfortunately, she wasn't sure which other world it was. Your aunt used her spare time to travel through the dimension again and again, looking for you for two years but finding nothing. Just when she was about to give up, that is, more than three months ago, she finally found you according to the exact news. If it's a step too late, you'll definitely be in the hands of the Demon God by now. “

My aunt had told him about crossing the dimensional world to find them, and she was not shocked by this, but Lu Tianyu didn't expect that his father was such a powerful person.

He also wanted to hear her talk more about her parents, but she changed her tone and said, "If you want to know about your parents, you can ask your aunt later." The teacher called you to talk to you about the national competition. How did you feel about last night's test?"

Lu Tianyu couldn't easily express his feelings. Now Shangguan Tianlong is still lying in the infirmary, and he doesn't know when he will wake up.

"With my current strength, I will definitely die if I participate in that competition. He said.

"Not necessarily. She picked up a ceramic cup of water on her desk, took a sip of water, cleared her throat, and continued, "It's certain that you will lose the tournament now." The teacher asks you, what are you going to do if you can't find a way to increase your magic powers?

Hearing this, Lu Tianyu knew that everything about herself was under her control. It seems that when she told her aunt that she would take care of herself, she didn't just talk about it. She's pretty reliable.

"But I don't have a demon yet. “

"It seems that you really didn't take this lesson in vain. If not, create one, isn't your dad also at your age inventing new magic. The teacher believes that you, who have inherited his genes, will be able to do the same. “

But when Lu Tianyu looked at her expression, it didn't look like she was joking.

"Teacher, are you making fun of me?" he was confused by her.

"How come?" she said expectantly, "didn't you say that in the world where you grew up, people can fly in the sky without magic, is it because of the envoy demon who created that machine?"

"......" Lu Tianyu almost collapsed in her heart, she just thought she was reliable, she was like an idiot!

"The teacher really wants to open his eyes, can you create one as well?"

"That's an airplane," Lu Tianyu couldn't cry or laugh, and tried his best to hold back his laughter, "It's impossible to build an airplane by myself." “

"Why not? Is there something missing here? If needed, the teacher can help you. “

Seeing the head teacher's expression like a little girl looking forward to Prince Charming, Lu Tianyu really couldn't bear to tell her that the plane was actually not a servant demon. But if you don't say it, I'm afraid that you will be questioned endlessly.

He couldn't help but regret a little that when he was asked about this more than a month ago, why didn't he tell her bluntly in the first place that the plane was just a means of transportation. Although airplanes are also used as tools of war by humans, compared to the envoys of this world, airplanes are thousands of times more terrifying.

"Teacher, there's really nothing I can do about this. He had no choice but to relent, "In the world where I grew up, airplanes were not used as envoys. You know, no one there uses magic. The only way for people to soar into the sky is with tools. The airplane is the tool we use to fly into the blue sky, it is not alive," Lu Tianyu pointed to the desk in front of her and continued, "but like this table, it is lifeless, it is dead." “

"Dead?" the head teacher's eyes widened, "how can a dead person fly into the sky?"

Lu Tianyu began to feel a headache. How can we explain things from another world to people from another world?

Just to explain how the airplane is made, it involves mathematics, physics, design, metallurgy, ...... This professional knowledge, and then explain how the plane goes to the sky, which involves a lot of complex problems such as aerodynamics, gravity, etc., he is not so knowledgeable. Even if he has all these professional knowledge, if he wants to explain it to her, he will have to talk about it for three days and three nights!

"Teacher, I don't know how to tell you to make it clear, you really want to know," he surrendered weakly, "You can also travel through the dimension and see that world for yourself, and you will understand everything." “

"Do you think I don't want that?" she suddenly became frustrated, "Crossing dimensions is not a trivial matter, you think everyone here is like your aunt. Hmph, the agent is convenient, and there is a way to go wherever you want. “

Lu Tianyu had long been curious about his aunt's identity, and he didn't know what the "surrogate" represented, so he took the opportunity to ask, "What does the surrogate mean?"

"Your aunt didn't tell you who she is?" she said, with a look of surprise.

"Nope. “

"This woman doesn't want to reveal her identity to her own nephew?" she sighed and continued, "The vicarious is the king's personal bodyguard, and each of them is a super-first-class magician, and they are given royal status, not subject to the restrictions of the wizarding world. Your aunt is a big man. We have only three agents in the entire Xuanzes Method. “

Lu Tianyu knew that her aunt's identity was not simple, but she didn't expect her identity to be so noble!
