As the clock ticked, so did the last holiday before the final exams, the Easter holidays.

Calvin had already planned for this vacation, and the first thing to be arranged was the Cedric and Weasley twins.

"Alright, kids," Calvin lazily lay on the couch, stroking Amor in his arms, looking at the three people sitting across from him, "you've been learning magic painting and alchemy with me for a long time, it's time to examine your learning."

"Professor Capet, we have final exams coming up soon." As soon as the words ended, one of the Weasley twins began to complain.

Calvin rubbed Amor's head and said nonchalantly, "Really? But as far as I know, you don't seem to be taking this final exam very seriously."

George wanted to argue a few more words, but Calvin's face changed, "Okay, I still have a lot to settle accounts with you two, do you really think I don't know anything?"

The Weasley twins lost their momentum, and Cedric sat on the side and snickered at the two of them.

"But don't worry, this time the assessment won't be too difficult. Cedric!"

Cedric, who was still smiling, straightened his back in an instant and looked at Calvin seriously.

"Didn't I teach you how to make a magic painting from a fluorescent spell two months ago? Your mission is to paint the Unconscious Charm into a magic painting." Calvin said lightly.

Cedric nodded solemnly, "No problem, Professor Capet."

Calvin turned his head to look at the twins, who were glaring at each other, and just as he was about to speak, Fred preemptively said, "Professor Capet, can you not give us a specific task?" We just have an alchemy artifact to finish."

Fred was talking about the two of them, a simplified and inferior version of the Beacon map, which, after dozens of failures, had already figured out some ways to do so with Cedric's help: just cast the Manifestation Charm on the map, and the map would show the location of everyone in the castle for thirty seconds, and it would take ten minutes before they could use the Manifestation Charm again.

Although it is not as effective as the living map made by the four predecessors, it is still more than enough to avoid Filch.

Calvin shook his head slightly, two silly boys, do you really think I don't know what you're messing with? Besides, your youth mini map is too far from what I asked. I can't agree to your request unless you actually get the live map.

"You're not qualified to negotiate terms with me yet." Calvin said, taking out a piece of parchment and patting it in front of the two of them, "Honestly do what I ask, and I'll help you perfect what you're working on."

The faces of the two changed, and they thought that their secrets could be kept secret from Professor Capet.

Fred took the parchment that Calvin had given them, looked at it carefully, and then began to complain again, "Professor Capet! Three alchemy products that can talk in pairs, isn't that too difficult for us?"

Calvin's eyes widened, "What a shout." You can make a communication bookmark before you study with me, and after studying with me for so long, you can't make it a little more difficult? Are you stupid or am I not good at teaching you?" ….

"You don't have to be too nervous, I have left you plenty of time, just leave it to me before the end of the semester, that is, you still have more than two months, and if you have any questions now, you can ask me one last question."

Cedric reflexively raised his hand and asked, "Professor Capet, what is the main difficulty in making a magic painting of the Stuna Charm?" What's the difference with a glow spell?"

"Oh, Mr. Diggory, I'm glad you asked," Calvin looked at Cedric approvingly, "but I can only give you some hints, otherwise this expedition will be meaningless."

Calvin set Amore aside, snapped his fingers, and a blackboard flew out of the corner.

"I should have told you that the first time you cast magic, or pursue the greater power of a spell, you need to mobilize your emotions. To make a stun spell into a magic painting, you need to mobilize more impulsive emotions. If you try a few times and still fail, you can try

Try to ask for help in other areas, such as drawing some magic characters on the magic paintings."

Calvin slapped the chalk dust off his hands and looked at the Weasley twins, "Is there anything wrong with you two?"

George said confidently, "No problem, Professor Capet, Fred and I already have some ideas, just record the information of the other two communicators on the communicator, and it won't be long before you can get the task you requested."

"But, Professor Capet," Fred scratched his head, "why only let us make three alchemical artifacts that can communicate with each other, I don't think we can make thirty of them."

The corners of Calvin's mouth rose slightly, "Yes, maybe it's not a problem for you to make thirty alchemy products that can communicate with each other, but what if it's three thousand? What about 30,000? There is a limit to the information that an alchemical artifact can carry. If you don't want to go out with a communicator the size of a Tebo warthog, think of something else."

Fred and George hung their heads, they didn't expect their plan to be rejected so quickly by Professor Capet.

"My advice to you is to make a large alchemy artifact to store all the communicator information, so that the communicator you make only needs to have two functions: receiving and sending." Calvin proposed some practical solutions for the two, after all, Calvin is very busy, and there are many things that are better left to others to do.

"Ah, yes, I didn't think of that," George hammered his palm excitedly, "and it will be much easier to add the communicator in the future."

Fred was also excited for a while, and took out the parchment on the spot to write down his thoughts. Calvin thought the alchemist-loving Weasley twins were so cute, and of course, it would be better if they didn't come and steal from their farm.

After the two calmed down, Fred seemed to remember something, and asked cautiously, "Professor Capet, do you know the Living Point Map?"

"yes, of course I do," Calvin looked at the three young wizards in front of him.

"Are you the previous owner of the Living Point Map? Or maybe you're one of the four inventors." George was a little excited, his expression was like that of a pilgrim, as if he had taken the four inventors as predecessors and role models in the world of pranks, of course, and that was true.

Calvin shook his head, "I'm just friends with the four inventors, and when they made this, I was ready to transfer to France."
