Dumbledore quickly grabbed Orion who was about to cast a spell.

He wiped the sweat from his forehead and said, "Alas~ It's not appropriate to do this in broad daylight. Fiendfyre is a powerful dark magic and can't be used carelessly!"

Orion nodded and said, "I understand, Principal. We can let him go if we carry some people on our backs, right?"

Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

Snape: Kevin? Humph! Just a cocky brat with a bit of talent.

Dumbledore: Kevin is such a good boy who would go to great lengths to help his friends.

Voldemort: Kevin, this unethical and despicable villain! He has attacked me with a crowbar every time I die!

Rowling travels through the world of Harry Potter and awakens to become a necromancer.

Having escaped Azkaban twice, he is famous (and infamous) in the wizarding world.

But he was hired by Hogwarts as a professor of Defense Against the Dark Arts.

Dumbledore: "Letting Rowling become a professor at Hogwarts is the best decision I have ever made in my life. But Rowling, why are you sitting in my seat?"

Snape: "You are definitely the next Dark Lord. I will keep an eye on you. Wait, why did you expel me?"

Professor McGonagall: "Rowling, I've told you many times that Transfiguration can't turn your pile of skeletons into a catgirl!"

...

Many years later.

Some people call Rowling the greatest wizard in the wizarding world after Dumbledore.

Some people also say that Rowling has influenced the atmosphere of the magical world and is a sinner of the magical world!

Some even say that Rowling becoming the headmaster of Hogwarts is a disgrace to Hogwarts!

Rowling, surrounded by the Scourge, sat on the golden chair in the Hogwarts Great Hall, looking helpless:

"How did I, a prisoner of Azkaban, get hired as a professor at Hogwarts and eventually become the headmaster?"

"It can only be said that a person's fate..."

"How does it feel to be given the name Rozier?" "Get lost!" "How can you be so heartless!" "Stop with that gloating look. And can you please stop bullying those three little ones and Malfoy? You're practically ruining them!" "Tch, what do you know? You're having fun outside, while I can only find my fun at Hogwarts." These were the days these two shameless rascals spent having fun at Hogwarts.

Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

【Taste buds bloom potion】 [A potion made of moonflower petals, Billy Wigg insect sting stinger juice and fire ash snake eggshells as the main ingredients, which can stimulate the existing flavor to the extreme, and excessive intake will cause convulsions and convulsions all over the body for up to an hour] Luke De Vere is quite satisfied with this pot of potion, and today's eight-eyed giant spider dragon's rest risotto must sell quickly. …… This is the legendary story of being able to see the introduction of everything and eventually becoming a potion master. But the problem now is that Professor Sprout wonders why I can grow herbs 100% alive, Professor Snape wonders why I can make a near-perfect potion, and Professor Trelawney doesn't understand why all my predictions come true...... Every professor wants to communicate with me after class, but I just want to go to the Room to make myself a Thunderbird Storm special. This book is again...

Traveling through the world of Harry Potter, Wayne awakened the Chaos Lord system. As long as he created chaos and violated school rules, he would be rewarded.

Thus, Hogwarts ushered in the most lively period.

Dumbledore: "A student life that does not violate school rules is incomplete, but Wayne... please restrain yourself."

McGonagall: "I thought the Weasley twins were invincible, but I didn't expect Wayne to be braver than them!"

Professor Sprout: "Since he came, the badger has become a flat-headed brother."

Snape: "Azkaban! He should be assigned to Azkaban!"

Voldemort: "Don't bother with the Son of Prophecy, I just want to kill Wayne Lawrence! Now, immediately, right away!"

Wayne spread his hands helplessly: "I'm just a little more lively, why do you keep urging me to graduate?"

Travel through the world of Harry Potter and obtain the [Positive Energy Explosion Attribute System].

As long as you do positive things, the relevant people may drop attributes.

"I picked up 1000 Occlumency experience points, and my Occlumency skill level reached max. I got the achievement: Spell Mastery!"

"I picked up 500 points of Potions experience, and my Potions skill level was upgraded to level 5. I got the achievement: Potions Master!"

"I picked up 1000 points of physical experience, and my physical fitness increased to level 7. I got the achievement: Tear a dragon apart with my bare hands!"

...

Snape: "Are you an expert in potions? You should be the one to take the potions class from now on!"

Dumbledore: "You can master all spells at once, and you are so positive! You are the hope of the wizarding world!"

Voldemort: "We are all wizards. What do you mean by tearing the earth apart with your bare hands? Also, how come you are more proficient in dark magic than I am?"

Looking at the various black magic spells at the maximum level on his panel, Lynch was speechless.

Do positive things, why is the attribute explosion rate of black magic so high?

He looked at the admiring eyes of the people in the magic world:

"Although I'm very proficient in the dark arts, that doesn't prevent me from being the most positive wizard in the world. No one should object, right?"

Also known as: [Reborn Man Learns Magic in England]

In order to honor his ancestors' magic tricks, a magician in the Dharma-Ending Age is about to perform a large-scale escape trick at the end of the century. However, he accidentally dies in the middle of the trick. When he opens his eyes again, he finds that he has been reborn as a foreigner.

But fortunately, my father's family is still a small farmer. Well, it's not big but it's something. What I couldn't get rid of in my previous life, I can finally get rid of in this life.

As a result, when he was eleven years old, he received a letter sent by an owl.

"I don't know how I ended up in the Snake Hospital. Is this something I can enter?"

"Okay, forget it, let's just give up and destroy it"

In this way, a young man who took playing badly as his creed but unexpectedly mastered the magic of life became the laughing stock of the Snake Courtyard.

A lazy little snake was born at this moment!

As a result, some weird things appeared, and strange things appeared in the "ordinary" Hogwarts, which could also help me practice. Then I started to give up, while pretending to restore the glory of my ancestors, but secretly: I need you to help me practice!
