Claire White walked downstairs to the office with a cloth bag in her hand, her steps were a little slow, and her right leg shrank unnaturally when she touched the steps.

She cursed secretly, when she reached the staircase on the third or fourth floor, she was already a little exhausted, and her body was very tired after many days of sleepless sleep and today's sudden change.

After a heavy gasp, she limped back to the office with a large cloth bag.

At this time, the Defence Against the Dark Arts classroom on the fourth floor was very noisy, and many students were talking about what had just happened.

Joel, as one of the protagonists of the incident, returned to his window seat with some impatience after answering several of the same questions from Eddie, Allen, and Haylis one by one.

He sensed that something was wrong with Professor White.

Judging from the strength she had shown before, there was no reason why she couldn't detect the female ghost's sneak attack intentions......

Combined with the terrible state of Professor White when he walked into the classroom, Joel knew that she was in trouble, which should echo the mandatory tasks issued by the system.

Eliminate the hidden danger that threatens Professor Wright's life...... Joel wondered what had happened to her?

The answer to this question bothered Joel for a long time, and he still couldn't find any useful clues.

At the end of March, Ms. Marchiban, from the Wizarding Examination Authority, sent a number of letters, negotiating with them to begin working on a complete solution to the magic curriculum for the remaining grades.

This series has already earned the British Ministry of Magic a lot of popularity and gold gallons overseas, much to the delight of the current Minister of Magic, Cornelius Fudge, who ordered the personnel of the Wizarding Examination Authority to keep in close contact with the CLBT Four, and to produce a follow-up series as soon as possible.

But for the four first-year students, the difficulty of the upper grade course is there, and only the four subjects of potions, charms, transfiguration, and history of magic, they can rely on their own accumulation to complete the production of teaching materials.

"How?" Joel sat in his chair in the dorm room and waved Ms. Marchban's reply, "Are we going to do this series again?" ”

The other three people in the dormitory sat on their chairs with sullen expressions, "The Ministry of Magic has given two options, the first is that each of us will enjoy 5% of the subsequent income of the CLBT magic course, and retain the copyright, which means that we are still the authors of the rest of the series." ”

"This 5% is the pre-tax income, according to the regulations of the British Ministry of Magic, we have to pay 12% tax on the part of our monthly income exceeding 50 gold galleons, which is not small." Sergei clasped his hands on his chest, closed his eyes and frowned.

"The second option is to accept the buyout offer made by the Ministry of Magic, and they will pay us a lump sum of 2W gold Galleons after tax, which is 5,000 Galleons for each person if the four of them are divided equally, but the monthly share will be gone."

"Do we have to sell it?" Eddie was a little reluctant, "We can produce a series of teaching assistants for one grade level every year......"

"No," Allen, who has been in business since childhood, objected, "Now this set of teaching and auxiliary materials is very popular overseas, and only by striking while the iron is hot can it have a good effect, if you wait for the first half of the year, this heat will pass." ”

"And we really can't make teaching materials for the upper grades at our current level, and it will be ridiculous and generous to force them to be ineffective, and from all sides, selling these proceeds to the British Ministry of Magic is the wisest choice." Joel analyzed.

"I think the share is higher than the buyout income," Sergei said, "as long as the total revenue of this CLBT worldwide exceeds 100,000 Galleons, we will not lose money."

"100,000 gold galleons...... Eddie felt that the gold gallons were piled up in front of him, and the golden light was shining brightly, which was particularly eye-catching.

"As long as you sell 5W of this course, you can get 10W of Galleons, which doesn't sound difficult, after all, there are so many potential customers." Allen also agreed with Sergei's choice.

The four members of the dormitory voted to pass, and Joel wrote a reply letter with a pen and ordered his owl Bobby to send it out.

Two days later, Ms. Marchiban's letter returned, containing a letter from Connelly Fudge, Minister of Magic, and a host of documents to be signed.

With everything all set out, Joel sat back in his chair with his hands crossed behind his head, comfortable and comfortable.

It's very happy to think that there will be a large amount of dividends in the account every month in the future.

Joel hummed a little song and pulled a piece of parchment from his History of Magic textbook, with clues scattered on it.

Every day at noon, after lunch in the auditorium, I go to the bathroom on the third floor to wash my hands, and on Tuesday and Friday afternoons it is laundry time, and I leave the castle on time on Saturday at 7 p.m. with a wooden box, and return to the castle at 7 a.m. on Monday......

This was the result of Joel's tracking of Professor White for the past two weeks, but fortunately there were many people in the castle, which did not arouse Professor White's suspicions.

Joel has been in this world for 7 months after dipping a quill in an inkwell and is fully accustomed to this Western medieval way of writing.

He was typing a draft next to him, trying to tie the various clues together.

Removing useless clues, Joel didn't believe that there was some kind of creature in Hogwarts Castle that could endanger Professor White's life, just kidding, now that Harry Potter has not yet entered school, the basilisk is nonsense, and besides, there are no Japanese schoolchildren in the castle, how can people die?

As such, Professor White's life is in danger only between 7 p.m. on Saturday and 7 a.m. on Monday, and only during this time Prof. White is not in the castle.

What did she leave here for?

Joel's quill slammed impatiently on the table, he thought of this and was gone, and in order to complete this mandatory task, he had to find out what Professor Wright was doing before he could make a move.

Or...... Leaving the castle with Professor White on Saturday?

A bold idea popped into his head, and the quill swiped aimlessly across the parchment.

Fight a wave, it's not a way to wait like this!

Joel made up his mind, and he called out the system panel, glancing in the Charms section.

Finally, he found the spell he was looking for.

Illusion Charm.

The progress bar below reads 0/250.

This spell is too expensive than a paste spell, isn't it?

Joel looked at the price for a while, but when he thought of the punishment for not completing the mandatory task, he was ruthless, 250 Galleons, Krypton!

The 250 gold Galleon top-up entered the system, and it was quickly cleared, and the Illusion Spell in the Spell column was completely lit, which marked the point where his understanding of this spell had reached the point of perfection.

It's terrifying, you can learn a spell in just 7 seconds, it's so amazing, it's all in the Pipi Shrimp Kryptonite system.
