After cleaning up Ivan, a restless fellow, Lucia was in a good mood and opened the door of her house humming a few little tunes. Prepare to cook a delicious lunch.

"Yo, what makes my precious granddaughter so happy? Say it and share it with grandpa. ”

"Grandpa, when did you come back? Didn't you go to the royal city? How come I didn't hear from you coming back. Lucia hurriedly ran over and gave the old man a hug.

"Isn't this just back, ready to surprise you. Tell me something you're happy about?"

"It's nothing!" the majestic teacher in front of Ivan actually showed the posture of a little daughter, "It's just to clean up the naughty students in the class." ”

"Looks like my baby is already enjoying being a teacher. How's it going? Grandpa's suggestion is not bad. The old man took what Lucia had in her hand and placed it on the table.

"Well, I didn't get used to it at first, but after a few days, I enjoyed the gradual progress of the students. It feels like planting flowers and grass. Lucia said and poured the old man a cup of tea. I moved the things on the table casually.

"What is this, paper, but it's too rough, Lucia, you made it?" the old man stumbled upon a few pieces of paper, and took them in his hand and looked at them carefully.

"Oh! How did I bring it back? I forgot to throw it away. That's what that naughty student came up with. It's a very smart student, but he always has some strange ideas and doesn't concentrate on learning magic. Lucia hated Ivan when she mentioned it.

"Which troublemaker made my darling angry? Grandpa helped you expel him, and I, the honorary dean, am not in vain. "The old man looks like I'm angry with you.

"It's so serious, I can handle my granddaughter myself, and besides, he's the best student I've taught so far. ”

"Then tell Grandpa how naughty he is. Grandpa helps you find a way to clean up and make sure to become a good child in no time. ”

"His name is Ivan, he always likes to be different, he has a three-line elemental affinity, he didn't listen to the persuasion of a teacher, he has to be a three-line initiate. In order to be able to learn the knowledge of the three departments, he asked me to tutor him. ”

"Wait, this kid actually asked my precious granddaughter to work for him, what a reversal!" the old man blew his beard and glared at his granddaughter when he heard that someone was bothering him.

"It's nothing! Grandpa, listen to me. Lucia couldn't stand the old man's sudden interruption.

"Okay, grandpa, don't interrupt. ”

"He likes to show off, it is a rare high-level spiritual power qualification, and when using the scroll, he has to use his eyes to release his mental power, and a large number of students follow the trend and cause the learning atmosphere to be sluggish. Speaking of this, Lucia remembered the malaise of the other students after trying and Ivan's pride, and couldn't help but laugh dumbly.

"Why do I sound so familiar...... the old man vaguely remembered something, and saw his granddaughter's dissatisfied eyes and made a sticky gesture.

"He has a strong learning ability, and he always dislikes the slow progress of the teacher's teaching, and asks me why the college doesn't compile the basic knowledge into a book and distribute a set to each student. What a whimsical rich boy!"

"I told him that neither the price of the paper nor the difficulty of transcribing the book was possible. The boy made his own paper. That's what he's made up, and this counts as paper?" Lucia didn't think much of what Ivan had made.

But the old man's eyes lit up, "What a boy with ideas, I think this is a good attention! This thing may be useful if it is improved and improved, but I don't know how to do it." I have time to help grandpa ask. ”

"Grandpa, you're also messing around, do you really think it's reliable? It's just a child's nonsense. Lucia couldn't believe what her grandfather said.

"Genius is revealed from childhood, and most new inventions are born from whims and accidents. Don't judge things right or wrong because of your age. The old man taught his granddaughter earnestly.

"You have a really high opinion of him, he comes back to me for tutoring at night, you ask him yourself, I can't pull my face. ”

"What? Come to your place at night to tutor! This little rabbit cub is really cowardly, tell grandpa if he has taken advantage of him. ”

The old man was furious at first, and then eagerly pulled his granddaughter to look left and right.

"Grandpa, if you want to die and talk nonsense, I'll kick you out, that's my student, a half-old child, what do you think!" Lucia was a little angry when she saw that her grandfather was talking nonsense.

"Who made my precious granddaughter so beautiful, grandpa was always worried about which pig would be arched. If you're looking for a lover, grandpa will have to take care of it. ”

Seeing that Grandpa was unrepentant and said something he didn't like, he turned around and walked inside.

"I'm going to make lunch. ”

......

Ivan didn't know that he had been remembered by a terrifying old man, and he was still thinking about how to win back the favor of the beautiful teacher.

"Hey, Hudson, how do you say to win back someone's favor? Ivan felt like a straight man of steel and asked Hudson for help.

"When did you have a girlfriend and you had a fight?" Hudson's eyes lit up and he smelled gossip.

"What are you thinking! Didn't I tell you about the morning, I still have to count on Teacher Lucia to tutor, and my favorability has been crazy lately, so I have to find a way. ”

Hudson had an expression that I understood, "Ivan, you are really evil, dare to attack the teacher, the teacher-student relationship must be very exciting." ”

Ivan felt that he should have opened Hudson's head and cleaned him. Otherwise, it's all filth, and no one will be saved.

"Speak human words!"

"Women, just say good things and give gifts. ”

"What should I give? I guess it's not uncommon for Teacher Lucia to be able to buy. Ivan felt that this attention was unreliable.

"It's the heart that matters, you know, for a goddess like Lucia, how can you live with a gift you bought?"

"Okay, I'll think about it, but Hudson, just talk nonsense in the dorm, don't talk nonsense outside, gossip hurts, you know? ”

"Hey, you're really boring, just kidding, I'm not someone who doesn't know how to measure. ”

After thinking about it, Evans was able to draw the table himself, so he spent a class drawing a stick figure comic strip.

After the afternoon class, Ivan had some dinner and went to Teacher Lucia's room, "Is Teacher Lucia there? I'm Ivan, I'm here for tuition." ”

It didn't take long for the door to open, and it seemed that the teacher wasn't really angry.

"The teacher seems to be in a good mood and the person is getting more and more beautiful. My fatigue in class disappeared instantly, and I was very much looking forward to the teacher's tutoring. Ivan remembered Hudson's guidance and praised the teacher's beauty and teaching.

"Really?"

"Of course, I was naughty this morning, and I made a gift to apologize to the teacher. Ivan said and showed his drawings to the teacher.

"Why is this picture the same? No, it's a little different. Lucia flipped through her coloring book.

"That's how it should be. Ivan took the small notebook, flicked it quickly, and a simple Ivan appeared, holding a bouquet of flowers and walked up to Lucia with a simple pen and bowed and apologized, and then was forgiven,

"It's interesting, how did you come up with that?" Lucia felt curious.

"I stumbled upon it, drawing a gradient picture in a notebook, and when you dial it, you will feel the picture moving. "Ivan made up a reason, it can't be said to be plagiarism.

"Really? Let the old man come and see it. ”

A serious voice suddenly sounded in the room, startling Ivan.

"Who?" he saw an old man sitting on the couch behind him. "I said, old man, are you invisible? I haven't noticed you for so long. ”

"Your boy's eyes are all on my precious granddaughter, where can you see me, an old man. The old man said sarcastically.

"Hey, aren't you the old man who tested your qualifications! you're Teacher Lucia's grandfather?" Ivan recognized the old man in surprise.

"It's not big or small, this is my grandfather, and the honorary dean of the academy, a senior magician, don't hurry up and salute!" Lucia urged.

"Hello Dean, the kid is rude, and please don't remember the villain. As soon as Ivan heard the identity of the old man, he immediately coaxed.

"Quite familiar, I heard Lucia say that you think that handing out books to students is good for the progress of teaching, and that you specialize in the new art of papermaking. The old man took out Ivan's confiscated paper sample, "You made this?"

"Yes, the students found that the impact of receiving scrolls and no books, the teacher's teaching progress was very slow, and the students had no materials to study, and the learning efficiency was very low. Those ordinary magical knowledge can be printed in books and distributed to every student. ”

It was only later that I learned from Ms. Lucia that paper was more expensive, so I tried to see if there was a cheap way to make it. These are the results, and they can't really be used yet. ”

"How did you make it, don't worry, the old man is not going to steal your work, but your idea is also feasible. The old man stroked his beard and said.

"That's fine. Then Ivan explained his idea and the production process.

"It's kind of interesting, but there's a fatal flaw to your approach. ”

"The paper is rough and easy to damage the pen?"

"No, you make it by crushing and soaking leaves or straw and adding bleach and sticky agents. But there is such a law in the world: the whole lasts forever, and the broken is perishable. It is said that the more complete the object, the longer it will exist, and the more broken it is, the faster it will decay. I'm afraid your paper won't last long!"

And this is the argument that is the difference in the world that causes the law of things to be very different? This is a profound question. Once again, Ivan felt the difference in the world.

However, it is worth verifying how long the paper can exist, and it is not impossible to use it if it can exist for three or five years.
