Hogwarts Card Drawer

The first class, because there is only one student. Chronos doesn't have much passion for teaching, instead he spends most of his time chatting with Owen Caldwell about homework.

Kronos learned from him that his father was a wizard and her mother was a Muggle, and a math teacher in the Muggle world.

"Oh~ no wonder." Kronos heard this, and he understood why it could pass his own test.

"However, Mr. Chronos, your topic is still a bit difficult for me. So, I bought this." Tong Owen took out the May 3 textbook written by Kronos from his schoolbag.

……………………………………………………….

October came, and the cold and damp mountain wind blew the whole castle. The doctor at Madame Pomfrey's castle suddenly found that more and more people were suffering from colds, which made her too busy to get out. So she specially developed a chili potion. Although after drinking this potion, the ears will spray smoke for several hours, but the medicine is really effective in curing the disease.

Since the first magic circle class, many people have passed the test of Chronos. This also includes Hermione, the student of Gryffindor, and Daphne Greengrass is the only student in Slytherin who passed. Draco often complained that Chronus's questions were too difficult, and asked Chronus to give him the easiest test paper. But when Draco asked "What is an angle?" Chronos gave up hope in him.

Kronos's magic circle class has also begun to step into the regular, but Kronos found that he still overestimated their understanding of geometry. Chronos can't speak a few words in a class, and he will be interrupted by a bunch of messy questions.

"Mr. Chronos, why is the sum of the interior angles of a triangle 360 ​​degrees?"

"Mr Chronos, why is an equilateral triangle an isosceles triangle and an isosceles triangle not an equilateral triangle?"

"Mr. Chronos, what is an isosceles right triangle?"

As for the most basic and simple figure like a triangle, Kronos insisted on inkling a lesson. Looking at the group of ignorant boys and girls in the classroom, Kronos finally realized the pain of being a teacher.

Kronos really wanted to open their giant heads to see what was inside, how could they not learn?

Kronos stretched out his hand, motioning for the student with a problem below to put down his raised right hand.

"Mr. Chronos, why do we have to learn these square things, I can't feel any magic in them?" The question was asked by a student of Ravenclaw - Molag McDougal .

"A student who likes to play tricks." Kronos complained in his heart.

Kronos did not answer his question directly, but looked at the other students and said, "Who remembers what I said in the last class about the distance of the magic circle?"

Hermione raised her right hand, and although Chronos was reluctant, she was the only one in the classroom who raised her right hand.

"Then, all right! You answer, Miss Granger." Chronos said.

Hermione stood up, still respectful in her class manner.

"The magic circle is a magic circle drawn by the magister with a good conductor of some magic power. A small amount of magic power is injected into the magic circle when drawing, so that it runs on a specific trajectory in the magic circle, and is in contact with the free magic power of the outside world during operation. They echo each other and attract the free magic power from the outside world, thereby enhancing the magic power of the caster to a certain extent." Hermione explained the meaning of the magic circle completely.

"Very well, ten points for Gryffindor." Kronos clapped his hands and said, he finally understood why some teachers liked students like Hermione so much. Not for anything else, just to save worry.

"The magic circle needs the magister to guide the magic power floating in nature through a specific trajectory,

And these so-called cubes that I am giving you now are the most important of the magic circle, the foundation of the foundation. " Kronos said later, the professor's majesty was inadvertently revealed in his words. Some of the seniors below were Kronos' seniors, but at this moment they also bowed their heads and remained silent, not daring to touch Kronos's Mildew.

"It seems that our Mr. McDougall didn't keep the content of my last class in mind. Ravenclaw deducted ten points and fined you to copy the interpretation of the magic circle ten times." Kronos said sternly, he Already somewhat liking the privilege of being able to deduct student marks at will.

Then Kronos turned his attention to the other students.

"But your level is so speechless. I thought you could easily pass the first few lessons if you passed my test." He said in a cold voice. "I will now tell you again the elements of geometry."

"To learn geometry well, you just need to memorize a few words." Kronos paused, and continued after seeing that the students below had all picked up their quills: "Geometry has four key words: point , line, surface, body."

"The relationship between them is that the point moves into a line, the line into a surface, and the surface into a body. Because the magic circle does not require you to learn three-dimensional geometry, you don't need to memorize or understand the following sentence."

Chronos was talking endlessly above, and there were bursts of "swipe, swipe, swipe" sound of quill pen writing on the paper below.

In the end, Chronos, like the other professors, assigned a host of homework assignments. There was no other reason. Seeing the painful expressions on the faces of the students, Kronos felt a sense of relief in his heart.

"I finally lived the life I hated the most when I was a child." Kronos touched his chin.

Chronos' classes are all on Friday afternoons, so the time of class depends entirely on Chronos' mood.

"It's Halloween again! It's a new year coming here again." Chronos walked in the corridor, and he saw the big pumpkin Hagrid planted outside his house through the window.

Chronos walked down the empty corridor sadly, the senior students had all gone to Hogsmeade. He turned a corner, and suddenly saw Harry in front of him, who was talking to Nick "Almost Headless", the ghost of Gryffindor.

Looking at the one person and one ghost in front of him, Kronos remembered the basilisk attack that happened at the Halloween party in the original book. Now Voldemort's notes are gone too, not in Hogwarts. Then something like this can't be happening. But for some reason, Kronos always felt that it was impossible to spend a school year in peace and stability in the same grade as Harry.
