Hogwarts Card Drawer

　　Kronos went to the auditorium for dinner with Draco after class. The food is still the same, potatoes, beef, and oatmeal, which will never be the same.

　　 I have to say that Hogwarts' owl efficiency is still very fast. Ron had just sent the owl letter in the morning and got a reply at noon. It was just another roaring letter.

　　 "Your wand is broken, it's all your fault." Mrs. Weasley roared in the auditorium with her voice amplified hundreds of times.

　　 Over the long Gryffindor table, Hermione showed them her homework in transfiguration class. Turn a beetle into a beautiful button. Ron's mood still didn't improve.

　　 "What class do you have in the afternoon?" Harry hurriedly changed the subject.

　　 "Defense against the Dark Arts class with the Slytherin students." Hermione said immediately.

　　 "Huh?" Ron wanted to grab the timetable in Hermione's book, and said in surprise, "What is this? Why are there circles and triangles drawn on it?"

　　 "I think it should be the papers for the magic circle class of Kronos?" Harry glanced aside and said that he had seen the magic circle made by Kronos in the Daily Prophet. The above pattern is a circle of blocks.

　　 "You don't really want to go to that...Kronos' magic circle class, do you?" Ron asked incredulously.

　　 Hermione snatched the paper back, and her face flushed with annoyance.

"Ron, if you think you are greater than Dumbledore. Then you don't have to go to any magic circle class. You know, even Dumbledore asked Chronos to teach at Hogwarts." When Hermione finished speaking, she picked up the book on the table and hurried away. In fact, she was not in a good mood, because she did not know many geometric questions on the paper.

　　 "Is she crazy? Did I prevent her from going? I just kindly ask!" Ron looked at Hermione's back and looked at Harry with a puzzled look.

　　 Harry shook his head, indicating that she didn't know. To be honest, he also wanted to get a paper, but considering the feelings of his friend Ron, he never went.

　　 On the Cronos side, he went out of the auditorium with Draco after dinner. They separated at the stairway, and Chronos did not go back to the Slytherin common room with them. In fact, he doesn't need to go back. Hogwarts professors all have their own lounges. Dumbledore would not deprive him of such power.

　　Cronos came to his office on the third floor, and he got inspiration from the group of students in the morning. I want to write a textbook about geometry in Muggle mathematics. Just compile some basic geometric theoretical knowledge into a book, and then copy it through the copying spell for hundreds of volumes. Finally, if you buy it to students, it might become the designated teaching material for Hogwarts. This is another substantial income.

　　 "Bang, bang, bang," Kronos was thinking when the door of his office was knocked.

　　 "Please come in." He didn't know who would come to him.

　　 looked up and found that it was the thin, tousled boy he saw at the sorting ceremony last night. He stared at Chronos in a daze. The sweat on his forehead showed his inner anxiety. He tightly held the ordinary camera used by people in the Muggle world.

　　 "Hello, Professor Slughorn. I—I'm Colin Crevey." He was almost out of breath, and he took a tentative step forward. "I'm Gryffindor College. Do you think—could—let me take a picture?" he raised the camera, hopefully he said.

　　 "Take a picture?" Cronos was taken aback, and then he reacted. In the second original book, the boy named Colin Crevey is Harry's little brother. Chasing Harry every day to take photos of Harry caused a lot of trouble to Harry. But the camera in his hand helped him avoid the attack of the basilisk.

　　 Speaking of the basilisk, Chronos remembered the diary. Cronos thought about it. He still believed that the diary should have been lost during the fight in Lihen Bookstore. At that time, he patronized and watched the excitement. Did not pay attention to the crucible in Ginny's hand at all. As for the basilisk in the secret room, Chronos looked at the contract card in his system space. Chronos now has enough mana to use it. Although he already has a toothless boy, he still wants to put that basilisk in his bag.

　　 "But...is it okay?" Colin was stunned for a long time seeing where Cronos was, thinking he didn't want to.

　　 "Ang?" Cronos was suddenly interrupted by someone and was very uncomfortable, but he still smiled and asked Colin to take some handsome photos of himself.

　　 "By the way, Colin. Could you please call Mr. Filch for me?" Cronos stopped Colin who was about to leave.

　　 "Of course, Professor Slughorn." Colin looked very excited, able to help the famous wizard in the wizarding world. He is very happy.

　　 After a while, Chronos’ door was knocked again~www.readwn.com~ Chronos knew that it was Filch outside the door this time.

　　 "Please come in." He said.

　　 As expected, Filch's face appeared from behind the door.

　　 "Professor Slughorn, are you looking for me?" Filch smiled at Cronos, his face dissatisfied with flattery.

　　 "Oh, yes. Mr. Filch, thank you for this morning and last night." Cronos said.

　　 "Don't thank me, Professor Slughorn. This...this is what I should do." Filch lowered his head excitedly, a little flattered.

　　 "Don't be like this, Mr. Filch." Cronos laughed, and Filch was a little bit disrespectful of him. "As you can see, I have run out of paper for writing. So I need to trouble you to bring me some new paper."

　　 "No...no trouble, it should be, it should be." Filch said, and hurriedly exited Cronos' office. When he left, he still closed the door gently.

　　 Cronos smiled, he is thinking about the geometry knowledge his teacher taught him when he was in school in his previous life. It's just that what I learned in my mind seems to be returned to the junior high school math teacher. He was only fortunate that the magic circle used only plane geometry. If it were three-dimensional geometry, Chronos would really be dead. The first famous magister in the wizarding world can only teach wizards to draw pictures, not theoretical knowledge.

　　 Fortunately, I only need to call them some simple magic arrays. I only need to write something about the nature of the triangle and the definition of the circle.

　　 After a while, Filch returned. He pushed the door and walked in. With him was a large pile of writing paper in his arms.

　　 Cronos wrote on the first piece of paper: "Five years of drawing, three years of simulation".
