This is what Ravenclaw looks like.

In this era when communication tools are not developed enough, it is still a bit troublesome to find paid services. Unlike later, you can find someone in the university substitute group and start a private chat to negotiate most university substitute matters.

He had to make a notice and post it on the bulletin board in the break room, so that people who saw it would contact the employer through the agreed method, and then conclude a deal after detailed discussions.

Fortunately, this job is not difficult. He can post the notices in the Ravenclaw lounge by himself, but he can put up the notices in the Hufflepuff and Gryffindor lounges with a little help from his classmates - a Si Ke completed this transaction which was regarded as a favor.

'Forget Slytherin, at this price, even if there are students over there who want to come, they will be crowded out by fellow students and refuse to come...'

After confirming that his notice was posted, Andrew complained inwardly as he walked towards the library - although this time he temporarily used transformation to imitate the effect of the Bubble Curse, it is theoretically feasible. To improve the success rate, he needs to make more theoretical preparations in some details.

"It's still almost interesting..."

Two days later, on Saturday, Andrew got up early and went to the empty classroom on the second floor, where he practiced transfiguration while waiting for the senior students who came to participate in the collaboration.

He has been trying to use different materials to make roses for the past two days, but due to the limitation of magic power, the flowers are always not simulated enough, and even some materials cannot even deform basic shapes due to their own material problems.

"Dun, dun, dun."

There was a knock on the door, which made Andrew, who was thinking about the failure of the flower in his hand, stunned for a moment - no, which student is so polite?

He hurriedly ran over to open the door. This was not a job fair or club recruitment. Effective communication and cooperation between the two parties is an important reason for your success.

"Ah, sorry, I was thinking about something and forgot to open the door."

He glanced at the person who came and was not sure of his grade, but he could tell that the person was a Hufflepuff student. "Come, sit here. I think we can communicate for a while before waiting for others."

The other party was obviously surprised by his appearance as a junior, but for Xi Ke's sake, he didn't say anything strange - San Xi Ke's hourly pay is definitely not low among students, and Nat is the magic one. The world's basic currency.

While briefly communicating and understanding the sixth-year student's class schedule, the other five seniors also came over. Most were sixth-year students, and only one fourth-year Ravenclaw also participated.

After simply asking the seniors to show off their hair-soaking spells and checking everyone's class schedule, Andrew unfortunately found that he had no choice.

Because only the sixth-grade Hufflepuff at the beginning had roughly the same class schedule as him, the others would basically only be able to discuss it together on weekends a week, and the rest of the overlapping rest time would not even exceed one day a week.

Moreover, this sixth-grade student has clear logic and passable expression skills - if there are no deductions for this aspect, there is really no way to refuse.

"Sorry, I should have marked the rest time. It was my mistake and caused everyone to run in vain."

While apologizing, Andrew paid each senior class three shiny Sickles - the price was a bit high for ordinary students, but it was definitely sincere enough.

Because everyone left with a smile, and happily told Andrew that if he has similar requirements next time, he can still contact them.

‘It’s a mistake to make a mistake, just try hard Dumbledore is enough - now I got to know a lot of upperclassmen who are willing to help others and have free time. ’

Andrew, who had reserved tickets on the outer wall of the Astronomy Tower, saw off the rest of the senior students and sat back in the empty seats. "Then, if nothing happens, we can start the experiment, Senior Nellie."

"You don't need to be so polite. I think it's best for us to call each other by name. According to your description, our subsequent communication will probably be much more than I imagined - forget it, let's just ignore the names. It's more convenient. ”

"Okay, please use the Bubble Charm again - is that okay?"

"certainly."

…

"Don't stop. Can you cast spells in this state?"

…

"It's perfect. Do you feel that it has restrictions on spell casting - for example, it reduces the effect of the spell or causes spell casting errors?"

"No? Wow, good."

"Please wait a moment while I go get some water."

"Ah, can you use the Clear Water Spring Curse? Great, then, wait a moment, I will use the transformation spell to control them into a water ball covering the Bubble Curse on your head - if there is any discomfort Please prompt me or just crush it."

“…”

"It can actually discharge the air directly...but there is no feeling of inhaling gas...it is not a purification type..."

"What an amazing spell..., how does it feel to be consumed in the water?"

"There is no difference, exactly the same as before?"

“…”

"Does running put pressure on the bubble spell? Do you feel that the spell dissipates faster?"

"Can I stand on my head?"

…

The morning passed quickly, and Nellie, who was always known for her good temper, had the urge to punch the new Ravenclaw student in front of her.

He had been tormented this morning. This underclassman was a very typical Ravenclaw - he had extraordinary exploratory power and imagination for unknown things.

In the morning, he was still happy to get this job that paid well among students, but now he envied those guys who took the money and left.

Merlin's beard! It's just a bubble head spell, and this junior kid named Andrew almost took it apart to study!

'I can't do it anymore. If I continue to work, I'm afraid I will die from those messy ideas! '

'He actually tried to corrode the bubble head spell with different liquids. How did he come up with it! '

When Nellie finished the spell and took a break, Andrew was writing the results of the last experiment - the magic was too magical, and if he studied it himself, it would definitely not meet most of the spell property analysis.

'As expected of a senior student, he can actually do such a thing! '

Many of the research was even added by him when he was thinking about the possibility, but the other party could complete it and even come up with the corresponding magic.

"The experiment in the morning was really perfect," Andrew praised sincerely, closing the notebook whose score dropped sharply in Nellie's eyes.

"Thank you very much for your cooperation, Senior Nellie."

Andrew took out a Galleon and said, "Thank you very much. This is my reward for the morning. Can we continue the experiment in the afternoon?"

'It's only been four hours since the experiment started in the morning! '

"Oh, of course. I don't have anything to do."

"Great, then, at 1:30 pm, in this empty classroom."

Andrew smiled - he had gained a lot this morning!
