Chapter 492: Exploration of Memory Magic
Both Professor McGonagall and Dumbledore found nothing wrong with their investigation of the letters.

Andrew could only sigh that the Meiwa girl group was indeed very impactful, and then he continued his vacation before school started.

But unfortunately, before he even had time to walk around the campus, he suddenly realized an important problem - school was about to start, and his dean was going to check the progress of the Oblivion Spell!
"Damn it, I was so busy communicating with the Ministry about Lockhart's victims that I forgot about this. The Memory Charm was assigned by the Headmaster!"

Although he didn't think his research progress could get ahead of the dean, and the victims would most likely have to rely on the dean to take action, it would be too bad if his own progress couldn't keep up.

"Although I have studied a lot, I am only able to cast spells skillfully at the moment. It is barely enough to scare outsiders, but it is definitely not enough to scare the dean."

His initial plan was good, but the progress was slowed down mainly in the last half month - after Dumbledore and Karkaroff finished talking, it took him too long just to figure that out, not to mention he had to prepare for the new semester's content.

"Don't worry, there is a solution. If the daydream spell Percy introduced is really effective, as long as we can delay it for enough time, we can still pass it."

Andrew calmed down and began to organize the notes he made on the Forgetfulness Spell and Memory Magic during this holiday, making sure they could link it with the Daydream Spell and improve their guesses more quickly.

"Actually, I did do something. If it weren't for Dumbledore's mess, I would definitely have caught up," Andrew began to delete the unsuccessful guesses from his own ideas and add new ones.

He had already read the notes left by Professor Lockhart once during the holidays. If he boasted a little, he could claim that he had inherited Professor Lockhart's perfect Oblivion Charm - although this did not affect his destruction of Professor Lockhart's hopes of being discharged from the hospital and all his wealth.

But that's not all, there are so many ways wizards use to influence memory.

The simplest and most expensive method is to use raw potion ingredients directly, such as the most expensive curled-wing demon venom - it can clear bad memories.

Andrew drank three pints of venom in one summer vacation, which is nearly three and a half liters. That stuff is much more valuable than the same volume of gold...

As for other equivalent potion ingredients, Andrew basically used all that he could get.

Then came the potions. There were seven commonly used memory-related potions, even the Veritaserum, which took a long time to make. Andrew prepared all of them at once.

Next came spells related to memory - he learned all he could find, but was stuck in further research when Dumbledore changed the competition format.

"I hope the daydream spell Percy mentioned is really strongly related to dreams, otherwise I will have to spend at least a few months developing related spells..."

'I haven't verified a lot, but according to current research, all memory magic is not physically erased. However, I haven't performed an autopsy on animals, and I can't be sure whether powerful spells will destroy the part of the brain used to record memories, but many cases have proven that they will not.'

He wrote quickly on a new piece of parchment.

[I still believe that common magical methods, at least those I know, only block or disrupt the reading of memories, but do not destroy that part of the memory - although the truth serum cannot break it, there must be more powerful spells to break it. ]

[I still regard dreams as a breakthrough. They are more gentle in mobilizing memories, and are more effective in shielding bad memories than ordinary Legilimency - but it still needs to be tested.]

[The modification of memory can be put later...The professor will not check this...]

Andrew tucked this one away as soon as he finished writing it.

[Research on enhancing memory through Legilimency is temporarily on hold...]

[Basically all potions have little effect on memory threads, but there is a potion specifically for clearing memory... very... this one is also on hold. ]

...

After making a rough list, Andrew knew what he should do.

He burned his complaints and headed for the Room of Requirement - now that Voldemort's diadem was gone, it was a comfortable place to practice magic.

"Everything is forgotten!"

"... "

"Everything is forgotten!"

...

-

"Good evening, Andrew! We are back!" Hal trotted back to the lounge first, "Thank you for the gift, otherwise I would have nothing this time!"

"what?"

Andrew turned his head in confusion, "Nothing left?"

"Yeah," Kevin laughed from behind, "We're planning to team up and kick him out of the academy. He's such a disgrace."

"what happened?"

Andrew suddenly became interested, and the headache caused by excessive practice disappeared completely.

"Tsk tsk, he was deceived by his own brother."

Kevin's eyebrows were dancing.

"My own brother, lied?"

Andrew's eyes widened - no, seriously?
"I remember you said, Hal, that your brother is not even eleven this year, so he can only come to Hogwarts to study next year, right?"

He confirmed again.

"Right, so let's expel him from the house. He is a disgrace to Ravenclaw."

Kevin nodded very seriously.

"I wasn't deceived. I just didn't know. That's all! Did you know that those damn gold coins would disappear?"

Hal tried to argue, but Kevin just sat down on his bed, "I'm not shameless enough to exchange souvenirs for my brother's gold."

"He paid extra for it. I didn't intend to cheat him at first, and I gave it to him at almost the same price! He spent too much money on snacks, and then found a lot of gold coins and forced me to buy it! And he didn't even want to compensate me when the gold coins disappeared! When mom found out, she not only didn't give me the money, she also laughed at me!"

"Almost how much?"

Andrew looked at Hal.

“Not doubled…”

Hal said hesitantly.

He is such a good brother who is like a twin...

Not doubled! You cheated the kids out of their pocket money! You, no wonder your mother didn't compensate you!

Auntie did a great job!

While they were laughing, Hughes and Hal also returned to school.

"Um, Andrew," Hal glanced at him, then stood over and compared, "Why do you seem to be taller than me?"

'Three more hours of growth time every day...'

But this news could not be told, so Andrew could only attribute it to the good food in school - and then everyone continued to laugh at this guy Hal.

"By the way, since Hal and the others have returned to school, the twins are back too... Forget it, I don't have the energy to do the experiment today, I'll come back tomorrow. The professor can't check tomorrow..."

Andrew thought about it in his mind, but finally gave up on checking the daydream spell right now.

"Wait a minute, there is another exciting news to be announced today. The rules of the Triwizard Tournament will be announced tonight...Finally, they don't need to be changed anymore."
