A day at Hogwarts

Now, Charles' alchemy class this year is a bit rushed, and he needs to start from scratch. This school year, he needs to finish the first and second grade content, and then finish the third and fourth grade courses in the fourth grade. It will be normal starting from the fifth grade.

The worst thing is that Percy's class has to go through the first to sixth grade courses before Christmas, and study the seventh grade courses for half a semester next year.

Professor Delacour spent half a class introducing the history of alchemy to the students, understanding its development, and then began to conduct experiments.

The students didn't react for a moment. The content in this textbook wasn't even covered. Why did they start doing experiments?

"This experiment is very simple." Professor Delacour lowered his voice and put a smile on his face, asking the students to relax.

He waved his magic wand, and a box in the corner opened. Glass bottles containing colorful potions, measuring cylinders, empty beakers and other materials flew out, as well as roses made of lead the size of soda bottle caps. There was a rose in front of each student. set.

"Everyone turn to the back of the textbook for test one," Professor Delacour said. "The lead discoloration test can begin."

"For thousands of years, the greatest wish of alchemists has been to turn cheap metals such as lead into precious gold, and many interesting results have been achieved during the research process."

"Many alchemists wanted to make lead the same color as gold and pretend it was gold, and they invented many methods for this."

The students began to experiment.

This experiment is really simple. First, use a graduated cylinder to measure two chemicals and mix them in a beaker. Then filter them. Then use a dropper to take the "dye" of your favorite color and add it to the filtered chemicals. Finally, put the rose made of lead into it. , it can be taken out in 3 to 5 minutes.

The purpose of the experiment is simple, to allow students to master the use of common tools such as measuring cylinders, droppers, and filter funnels, and to intuitively experience the changes in objects caused by alchemy.

The most important thing is that the experiment is very safe. The medicine used is very mature and not very toxic. It can be rescued after drinking too much. Even if Simo mixes it with his eyes closed, it will not explode. It is very suitable for an eleven-year-old newbie.

The thirteen-year-old beginners also found it very interesting and followed the steps in the textbook attentively.

"What are you doing!"

Hermione had prepared the potion and had just put her lead rose in it when she saw Charles throwing something into his beaker.

Charles smiled and said, "Do me a favor."

After he finished speaking, he threw something into someone else's beaker.

When the time came, the students began salvaging.

"Wow!" Lavender Brown held his result in the palm of his hand and handed it to Parvati Patil next to him, "Is it beautiful?"

The originally gray rose turned purple at this time, beautifully reflecting the metallic luster in the bright classroom, which was very beautiful.

Parvati also showed Lavender her results. Her roses were as pure white as snow and more dazzling than Lavender's.

Charles' results began to be passed among his classmates. He took apart the roses, dyed them in different colors with different classmates, and finally assembled a colorful rose.

Professor Delacour was checking everyone's results in the classroom. Ron's rose looked messed up. Although it was dyed red, it had no metallic luster, like chalk in front of a blackboard.

"Here," Professor Delacour pointed to the section on the use of a measuring cylinder in the textbook, "In addition to homework, take the picture and copy it five times. During this period, think carefully about your operation."

Dean Thomas' Blue Rose has a metallic luster, but the color is uneven and has the color of lead in the stars.

Professor Delacour said: "Copy the filtering part ten times. This is not a step that can be taken lightly."

"Beautiful!" Professor Delacour was very satisfied with Parvati's work. "The use of the potion is very standard and perfect. You win two points for your college!"

Parvati didn't react for a moment, and after a while she became extremely excited. This was the first time someone had scored extra points before Hermione and Charles.

Along the way, only Parvati and Hermione got extra points in the classroom, and several people copied the text.

There is one person who is even worse.

Professor Delacour walked to the podium without even looking at Charles's work. His expression became extremely serious. He raised the textbook and opened the first page. There was "Alchemy Safety Code".

"I think everyone has read the code." He looked around at the students. "Everyone must realize that behind every content of the code are painful lessons, and many of them are committed by people who think they are smart."

"Today's test is very safe, but that doesn't mean that future tests will be the same. Some tests are better to wear armor so that you don't have to scrape people off the walls and ceilings bit by bit after making mistakes."

He looked at Charles expressionlessly and said, "Being cautious is the biggest source of danger."

The rest of the class was spent in safety education using Charles as a negative example.

Just now, Charles put lead petals into someone else's beaker. This behavior is a serious violation of safety regulations. Even if there are no serious consequences, he must be severely criticized and punished to eliminate the source of the accident.

Professor Delacour waved his wand and took out a sky-blue quill pen from the podium. Then he tapped Charles' head with the wand first, then tapped the quill. After giving the pen to him, he said: "Use this pen to secure the safe." Copy the code twenty times.”

The bell rang and the students left the classroom to go to Transfiguration class, but Charles had to stay and clean up.

Professor Delacour came to the professor's lounge, where several professors were resting.

There was tea and snacks here. He poured himself a cup of tea. After sitting down, he looked around, especially the shelf where the snacks were placed.

Professor McGonagall was preparing books for the next class. When she saw it, she smiled and said to him, "I'm sorry, Henry, we haven't been able to prepare French snacks yet."

Professor Flitwick also smiled and said: "If you don't like the snacks here, I can ask my wife to prepare some. I'm not boasting, her cooking skills are top-notch."

"Thank you very much." Professor Delacour said, "I am very familiar with the snacks at Hogwarts. Charles often brings snacks to Gabrielle."

"I'm not greedy, I'm just curious. During the summer vacation, Charles brought a kind of dried meat with a unique flavor. He said it was a specialty that can only be found at Hogwarts."

Professor McGonagall and Professor Flitwick's faces suddenly turned dark, and Snape's face, which had been silent, turned even darker. They all saw it when Charles was cutting the basilisk's flesh.

Professor Delacour read the atmosphere, realized something was wrong, and immediately changed the subject: "Charles is a very smart kid, and he always has dazzling ideas, but sometimes he is too smart."

"Yes." Professor McGonagall looked a little troubled. "Not only is he smart, he is also very courageous and very capable. He can do whatever he thinks of."

"The content of my next class would be dangerous if I try it privately. I'm a little worried that he will try it."
