[ps: Don’t join Ron’s party, I don’t like this character]

My name is Leggett Black.

After crossing over, I obtained a system....

It was also from this day that the world began to emit shrill screams.

Tang: Damn it, who stole my true energy!!!

Yu: "Ahhhhhhhhhhh!!! Oh my god!!!"

Jia Zhang: "Old Jia, please come back and take this thief away!!!"

In short, this is a story about exchanging everything in the Harry Potter world...

The shadow cast by two generations of Dark Lords gradually dissipated.

The White Lord (crossed out), the greatest wizard of this century, fantasized about receiving woolen socks in the headmaster's office.

Ryan Wells lived a quiet and leisurely life at Hogwarts.

With some insignificant external help, he was held in deep reverence throughout the wizarding community.

"Master Ryan! Do you have any new prophecies today?" People traveled thousands of miles from all over the world to Hogwarts in the hope of receiving a prophecy.

"Senior Ryan, what should I pay attention to today?" asked the younger students who had been helped.

"Ryan, any new prophecies?" Professor Flitwick cast a levitation spell on himself and patted his favorite student's shoulder affectionately in mid-air.

"Mr. Wells, what are your thoughts on the Ministry of Magic's future work?" asked the Daily Prophet reporter...

Dementors are evil magical creatures that have no facial features and can only distinguish living people by smell and the emotions floating in the air.

Wherever they go, all happiness will disappear, leaving only the deepest fear in people's hearts.

Legend has it that under the hood of the Dementor there is a face that can devour souls...

"That's the theory."

Cohen Norton did not deny this.

"But this doesn't affect my desire to be a good person. No, it's weird."

As he said that, Cohen licked the lollipop in his hand and turned a blind eye to the child next to him who was crying because the candy Cohen's brother gave him suddenly disappeared.

[Ding! Goodwill value +1, sin value +1]

[Note: Giving candy first and then snatching it is immoral and you will be condemned by your conscience]

(This is a story about a funny person who travels through time to the magical world, becomes a subject of some evil black magic experiment and grows up positively and healthily - just listen to it seriously)

- The following is an incomplete introduction -

"What is this, Tom Riddle's diary? There's a soul in it, take a sip."

"What is this, Slytherin's locket? Pry it open and take a sip like an oyster."

"What is this, Hufflepuff's cup? Add some milk tea and take a sip."

...

"What is this, Harry Potter? You smell good, bro, sip--"

"Cohen, don't come over here!"

[Harry Potter fan fiction + professor writing + education reform + layout + make up for regrets after the main story begins]

[Slowly warming up! There are new education reforms every year]

Sebastian Swann, an outstanding graduate of Slytherin, heir of an ancient alchemy family, and the richest man in the wizarding world. 12 years after graduation, he returned to Hogwarts as a professor...

Snape: "Sebastian, what made our richest man choose to be a little professor at Hogwarts?"

Sebastian: "To make Slytherin great again!"

Snape: "Tell the truth..."

Sebastian: "To make Hogwarts great again! ... Put away the truth serum, Severus, you are such a bore!"

Snape: "Tell the truth!!!"

Sebastian: "It's all true, except... I still want to make wizards great again!!!"

......

ps：

1. The protagonist graduated from Slytherin, is Snape's friend, and is not very friendly to the deer dog

2. The original female protagonist (a tool person) has no sweet love. The male protagonist is focused on his career and has no children for the time being.

3. Focus on Slytherin's shrewdness and ambition, not bloodline

4. Contains two settings

5. The timeline begins in the second year of the Weasley twins, one year before Harry and the other two enter school.

6. Lightning avoidance: This is the White Lord!!! Not the Dark Lord!

Harry's diary:

On 1991/6/23, I traveled to another world and was adopted by a couple. They were both very gentle, much better than my aunt's family!

On July 31, 1991, I returned to my original world and received a mysterious email. Oh my God, it was a magic school!

1991/8/8 I saved the world's richest man, Tony Stark!

On 9/9/1991, I encountered a mysterious man. He seemed... very weak?

1991/10/10 I was accepted as a disciple by the Supreme Sorcerer. Relying on the magic power in my body, I don’t need to pay the price like others!

1991/11/11 I became the greatest wizard ever!

...

Many years later, the Supreme Sorcerer, the Master of Chaos, the Third Dark Lord, and the Most Powerful Wizard in History, Harry Potter, faced the crazy reporters and said calmly: "

Thanos may be very weak, but he is right about one thing, the world needs a new order!"

This book is also known as: Harry's Journey Back and Forth Across the World, the Birth of the Greatest Wizard, the Mysterious Man Who Fears the Latitude Demon God

Through the mist of history, across the boundary between this world and the next.

Avalon, please show the truth of the world to the wanderers.

"My dream used to be to become a best-selling fairy tale writer in the Muggle and wizard worlds."

The reporter from the Daily Prophet raised the microphone, "What about now?"

"I have written my life into a fairy tale that I am most satisfied with... Look, whether it is Muggles or wizards, is there anyone who can refuse my story?"

On the day he crossed the world of Harry Potter and received the admission notice, Ethan awakened the achievement system. As long as he made the corresponding events, he could get rewards.

With three million gold, he has achieved the achievement of [hegemony and wealth can rival the country].

Get the blood of magical animals and achieve the achievement [I'm not a human].

Use Avadaso's life to kill 100 wizards and achieve the achievement of [Gnawing Big Melon Lover].

......

On the day of graduation, when Ethan was seamlessly appointed Minister of Magic, the reporter of The Prophet's Daily asked:

"Mr. Adrian, as the youngest and best Minister of Magic in history, I heard that you have been famous for Hogwarts in the first year of admission, won the Merlin Order Medal in two years, and directly overturned the professor in three years... I don't know why you have achieved such dazzling results?"

Ethan Adrian spread his hands: "I really want to make progress!"

Traveling to the magical world, Aaron became the heir of an ancient magician family and has been the hope of the family since his birth.

Until an owl delivered a letter of admission to Hogwarts, he resolutely packed his baggage and embarked on the road to pursue freedom.

He thought that as long as the final boss, Voldemort, died, he would be able to sit back and relax, but he gradually discovered that the world was not as simple as he thought…
