Dynavale and Hogwarts

Since there were no classes the next day, Dana was in the Room of Requirement and started researching alchemical potions suitable for "Echo".

Dana is no longer a novice in alchemy. After coming out of the initial fear of difficulty, Dana found an idea.

He realized that he had thought wrong before.

Although the magic track in "Echo" has the most suitable alchemical potion, it requires finding the right material from tens of thousands of alchemical materials, and constantly experimenting to find out the configuration process. You can imagine the time and energy required.

But what if we don’t pursue perfection so much?

You can try it with several general-purpose alchemical potions that have strong universal applicability, and maybe the effect will be good.

And it's just an alchemy item with a simple function, so it's not worth spending so much effort on. I always like to pursue perfection, so I subconsciously go in the most difficult direction.

I actually forgot that there are several general alchemical potions in my storage ring.

Dana used the transfiguration technique to wrap his spirit in a universal alchemy potion and carve magic traces into the chalcocite. In this way, I made several samples using different general alchemical potions.

Now that all the samples are in recording mode, Dana immediately performs a magical "war dance" and the chirping of the Chongming bird sounds.

Dana thought, just give it a try. After recording, the courageous special effect of the Chongming bird's chirping is still there.

In order to test the performance of the sample during long-term recording, the "war dance" lasted for an hour. Fortunately, as long as you run the magic track once, the magic will automatically cycle without any effort.

Afterwards, Dana listened to several samples, and one of them worked best, even retaining some of the special effects of Chongming bird calls.

Once the alchemy potion problem is solved, the remaining problems will be much easier.

Add a control pattern to start and stop recording and start and stop playback on the pattern of the magic track, cover it with a layer of anti-cracking pattern, and the improved "echo" is completed.

After thinking about it, Dana did not go back and redo the products that had been made before, but instead refined many new products according to new designs.

Not all alchemy products in the magic world are known to me, and there may be products with the same function. Then the low-priced "Echo" is more competitive when the recording time is not long.

So no need to redo it. The new "Echo", well, you can call it "Long Echo", is a new product of its kind, suitable for situations where long recording and playback time is required.

Dana was in a good mood after leaving the Room of Requirement. She had a huge appetite during dinner and kept eating, eventually scaring the roommates around her.

Justin asked timidly: "Dana, are you okay? Do you want to go see Madam Pomfrey?"

Dana was stunned and followed his roommate's gaze. Hey, there was already a pile of empty plates, plates, and cups. Somewhat embarrassed, he said nervously: "I didn't have lunch, so"

Everyone around him gave him a blank stare, even if he didn't eat for three days, he wouldn't be like this.

Dana thought happily that maybe he would grow taller.

My mind and magic power have grown rapidly recently, and I didn't expect that my body has also begun to develop further.

After dinner, I found Jiawen, handed him the newly made "Long Ring", and chatted with him for a while about my thoughts.

Jiawen said he understood, and at the same time he thought it was a great idea to give a few "long rings" to teachers for trial use.

Dana will give it to Professors Sprout, McGonagall, and Flitwick, while Jarvan volunteers to give it to Professor Lockhart. Regardless, he is considered a celebrity in the wizarding world.

Dana also thinks it's good, and maybe there will be an audio version of "Breaking with the Ghost" "Listen to Lockhart telling you about his adventures". Well, book fans should buy it.

Then wish Jiawen good luck

The next day, Dana and Professor Kettleburn were patrolling the Forbidden Forest. It had been a long time since Dana had come, and Dana was still thinking about it.

"I'm planning to retire next academic year." Professor Kegelborn's words startled Dana, who was still intoxicated in the Forbidden Forest.

Seeing Dana's confused eyes, the professor pointed to the scars on his body and said, "When it comes to rainy days, my whole body feels uncomfortable. Maybe I should find a warmer place to retire."

"Professor, magic is so amazing, why can't it heal these injuries?"

"It is precisely because magic is so magical that it cannot heal these injuries."

The professor's answer made Dana fall silent, looking down at the ground, feeling a little sad.

After a while, Dana opened his mouth: "Professor, what are you going to do when you retire?"

The professor laughed: "There are many things I want to do: maybe write a book about magical animals like Newt Scamander, who is also a Hufflepuff by the way; maybe go to a dragon breeding base in Romania to study fire dragons, It's really addictive; maybe the Muggle Manual you gave me gave me a lot of inspiration for developing magical zoology more fully."

Dana was also infected by the professor's cheerful mood. It seemed that the professor was full of longing for life after retirement.

The two of them made the rounds, discussing Muggle methods of studying animals. The professor admired Muggles' method of classifying living things. Phylum, class, order, family, genus, and species clearly arranged various living things.

Unlike the magical world, which only has a rough classification according to the degree of danger, and according to the professor's opinion, the dangers of many magical animals have been "artificially exaggerated."

Dana glanced at the scarred professor and expressed serious doubts about his statement.

I thought today's inspection would end smoothly like this, but Ronan, a centaur with red hair and a red body, appeared in front of the professor and said to the professor: "The Acromantulas have begun to overflow in the forest again."

This scene made Dana feel as if history was repeating itself.

Sure enough, the professor hurried away again and entrusted Dana to Ronan.

"The recent horoscopes have been unusual," Ronan said, in the same line.

"Really? But I don't know anything." Dana was determined to put an end to this strange repetitive feeling.

"Yes, you really don't know anything, because the stars are normal. I believe you have the ability to predict." Ronan smiled slyly.

Dana explained seriously: "My ability is not to predict, but to predict. Based on existing clues, information and conditions, I can predict what will happen in the future."

"It's the same, it's the same for destiny, it needs to be marked and paid attention to." Ronan said meaningfully, and then left. It was as if he came here today just to say this to Dana.

Dana was a little confused as to what it meant to be marked and paid attention to by fate. This is something that people dislike about horse people, they always talk in a cloudy manner.

Don’t think too much, instead of thinking about these things, think about something practical. Like what to have for dinner?

In his imagination, Dana saw the professor coming over in disheveled clothes, and hurriedly left the Forbidden Forest with Dana. After leaving the Forbidden Forest, he walked towards Hagrid's wooden house. The damn repetitive feeling is back.

Dana lamented that if he were a professor and repeated this day after day, he would probably retire long ago.
