Mysterious Walker at Hogwarts

Dean looked at Snape in surprise: "Professor, don't you think it's a bit overwhelming for me to memorize the recipes in "Advanced Potion Making" now?"

Snape smiled inexplicably: "That's your problem."

After saying that, he didn't give Dean any chance to bargain and left the classroom without looking back.

"Okay, even if you want to make things difficult for me, at least give me a new book -" Dean helplessly flipped through this shabby book from an unknown age, and suddenly his eyes widened.

On the back cover of the book, in small, dense handwriting, it says, "This book belongs to the Half-Blood Prince."

Could it be that... Dean immediately began to check the book seriously, and sure enough, almost every page of the book had many annotations written in the same handwriting - when Dean found the "Shen Feng Wu Ying" spell written in the blank space of the page , and when there were three interesting words "to the enemy" below, he was finally sure.

This "Advanced Potion Making" is Snape's old book that Harry obtained in the original book.

It was from this book that Harry learned several powerful spells developed by Snape, such as "Shadow's Edge", "Upside Down Golden Bell", "Golden Bell Falling to the Ground", "Lock Tongue and Throat Seal".

Dean was convinced. Snape, an arrogant guy, was originally going to fulfill his promise in this subtle way.

Dean was very satisfied with Snape's arrangement, which meant that he could not only use the activated Shadowless Blade openly, but also had the opportunity to learn other spells developed by Snape, and even pass Snape's spells in the book. Dispensing experience to make your dispensing skills even better.

Although "Potion Specialization" can passively improve Dean's success rate and efficacy of dispensing, it cannot do anything about dispensing techniques and techniques. This book can help Dean make up for this shortcoming.

The only regret is that this book does not contain the counter-curse of "Shadow's Edge", but Dean believes that he can definitely learn it from Snape after he has mastered all the contents in the book.

Dean was satisfied and put this "Advanced Potion Making" into his dragon skin bag. To him, this book was simply a treasure.

When Dean returned to the Gryffindor common room and saw Harry covered in mud from Quidditch training, he suddenly felt something in his heart: He had now taken away the Half-Blood Prince's "Advanced Potion Making". What about Harry in sixth grade?Does this count as changing history?

After thinking about it carefully, Dean felt relieved. The worst he could do was put this book in the potions locker in sixth grade, or find an opportunity to exchange the old books Harry got.

Dean thought this was more reasonable. It was hard to imagine that a cautious person like Snape would just stuff this precious book into his locker and it would happen to be obtained by Harry - if someone hadn't specially arranged it, haha Lee's luck is too good.

Now let Dean be the one who arranged it behind the scenes.

"Hey, buddy, you got detention from Snape again?" Just when Dean was thinking, Seamus came over and hugged his neck.

"Nothing, Professor Snape asked me to help tidy up the Potions classroom." Dean casually said.

"Humph, Snape always bullies us Gryffindors, and he never asks the Slytherin students to deal with it." Ron said angrily.

"Every dean will take care of the students in his own college as much as possible. This is normal." Dean said fairly.

"You actually speak for Snape? Let me check quickly. Have you been cast by the Imperius Curse?" Seamus shouted in a fuss. "Seamus, no one is bold enough to cast the Imperius Curse on a student at Hogwarts, especially a professor!" Dean looked at Seamus angrily. This guy was a little confused about the importance.

"Hey, man, it's just a joke~" Seamus said nonchalantly.

"This joke is not funny at all." Dean muttered and asked, "What were you discussing just now?"

"Quidditch!" Ron said with excitement, "We originally wanted to watch Harry's Quidditch training, but Wood refused."

"So you pestered Harry and asked him to tell you?" Dean asked.

"Yes, that's it. You came back just in time, Harry hasn't started yet." Ron said.

Dean glanced at Harry, who was slightly embarrassed, and immediately guessed his difficulty: "I think you should at least let Harry take a hot bath first. He must be freezing when training in such bad weather—— I guess you don’t want the Seeker to miss the game with a cold before he even gets on the field, do you?”

"Well, you're right!" Ron slapped his head and quickly pushed Harry and said, "Hurry up and go~"

"And I think that since Wood won't let you visit their training, he must be preparing secret tactics, so it's best not to ask too many questions." Dean added, while his eyes fell on Seamus.

"What are you looking at me doing?" Seamo was confused, and everyone else understood what Dean meant.

Except for Seamus himself, all Gryffindors knew the power of his big mouth. If something was known to him, it basically meant that the whole school knew about it.

In order to win, Gryffindors are willing to temporarily suppress their curiosity.

Harry, who was about to take a bath, gave Dean a grateful glance. If he hadn't come to the rescue, it would have been difficult for Harry to refuse the enthusiastic requests of others.

"Then can't we do something?" Ron was obviously a little disappointed.

He originally wanted to take advantage of Charlie being the Gryffindor Quidditch captain to give Harry some constructive suggestions, but it all came to nothing.

"How about we think about how to cheer Harry up?" Dean suggested - he would have been too lazy to meddle if the system hadn't just thrown out a task.

"Mission: Support Gryffindor

The first Quidditch match after the start of school is coming, and hosts who are not Quidditch players must find ways to participate and contribute to Gryffindor winning the game.

Reward: If Gryffindor wins, gain +100 flying skills and 2 skill points. "

Well, while it's not quite clear whether the so-called "flying skills" are limited to broomsticks or whether they apply to all flying, there's no way Dean is giving up on this mission.

"What do you think?" Ron asked.

"How about a cheering banner?" Dean asked thoughtfully.

"What is that?" Ron obviously didn't understand.

"In the Muggle world, we often pull out banners to cheer for the teams we support, with morale-boosting words like 'come on' and 'must win' written on them," Dean explained.

"That seems like a good idea," said Neville, who had remained silent.

After Harry, the protagonist, left, the senior students were obviously not interested in Dean's suggestions and dispersed one after another. In the blink of an eye, no one was left in the common room.

In the end, only the four roommates and Hermione were left, and they decided to take Dean's suggestion and make a cheering banner.
