The "Savior Training Manual," which details a life of leisure before encountering a ruthless killer, lists various activities from cooking, washing floors, and dishwashing to studying, running, and fighting. It emphasizes that persistence leads to proficiency, with occasional bursts of magical knowledge and even the acquisition of magical creature attributes upon leveling up. The manual then addresses the question: "Whose savior spends all day mopping and weeding?! Why is my skill still called 'Weeding' even though I can teleport?! Who wants the golden talent of the Exploding Tail Snail's fart?! Can't I just follow the storyline?!" The manual concludes with: "No! ...Four years later, in the Hogwarts Headmaster's office, Dumbledore unearths long-sealed letters. The manual outlines a training schedule: 5:00-5:30 sprint 10 laps around the neighborhood (youthful energy is amazing!) 5:30-6:00 do a handstand on one finger (what does a handstand on one finger even mean!) 6:20-7:00 weeding...

Professor McGonagall: "!!" "Ding! Gold treasure chest 1!"

Dumbledore: "Huh? What did you say your last name is?" "Ding! Supreme treasure chest 1" Black

Voldemort: Avada...

Black: "I'm just a little badger who wants to become stronger, what bad thoughts can I have?" (Spreading hands)

Allen, a programmer, transmigrates to the Harry Potter world and gains the unique talent of random partial transfiguration each day.

In Flying Class, he sprouts wings.

Exploring the Forbidden Forest, he grows a turtle shell.

To heal himself, he transforms a unicorn's hoof.

And because of a transformed tongue, he develops a deep, bitter feud with Voldemort.

Elephant ears, a snake's nose, a phoenix's eyes, an octopus's tentacles, a giraffe's neck, penguin legs, a peacock's tail, dragon scales...

These transformations bring him all sorts of advantages and troubles...

They also lead him, step by step, to understand the magical essence of this world, pushing Transfiguration to new heights.

He initially just wanted to protect himself and stay far away from trouble, but to his surprise, trouble kept finding him.

Even more unexpectedly, in this magical world, he even started using programming concepts to DIY all sorts of transformed beasts...

It's the new school year. Hermione Granger, who returned to school after summer vacation, welcomed the Muggle Studies class she had been looking forward to. The enlightened Professor Lewynter showed movies in class, but these movies... seemed to be a little wrong.

Azkaban Redemption

Sirius Black: You know some dogs are not meant to be caged, freedom shines in every strand of their fur.

Infernal Affairs

Wormtail: You undercover guys are really interesting, always meeting in the cemetery.

Snape: I'm not like you, I'm honest.

Wormtail: Give me a chance.

Snape: How can I give you a chance?

Wormtail: I had no choice before, now I want to be a good person.

Snape: Okay, tell Mad-Eye and see if he tells you to be a good person.

Wormtail: That means my death.

Snape: Excuse me, I'm from the Order of the Phoenix.

Wormtail: Who would believe that?

Memento

Bertha Jorkins: Someone has been messing with my memory. At first I just forgot the afternoon, then I started to lose track of dates and what I had for breakfast…

I wanted to visit my aunt in Albania before I lost all memory of her, and Mr. Crouch was very considerate in granting me this leave.

Crouch?

I seem to remember something, a great secret.

Danger is approaching.

Now,

who I am?

Where am I?

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..."

Reborn in Hogwarts, I thought I was the protagonist, but I turned out to be Harry Potter's cousin?

Although I don't have magical talent, at least I can look directly at Dementors, my magic resistance is full, and my strength is so strong that bricks can fly.

Dudley is a miracle!

No suitable wand?

I think the street lamp in front of Ollivander's store is very handy!

Can't levitate?

Can't you float up by waving your wand to create a tornado?

The troll in the bathroom?

Finally, there is a qualified boxing opponent!

Harry couldn't help but hold his forehead: Is my cousin really not Hagrid's illegitimate son?

The five-star Death Eater general Voldemort also cried out: He punched my nose in!

"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!"
