"Albus Dumbledore made two great mistakes in his life: one was Tom Riddle, and the other was Jim Lynch." Jim Lynch, the "Mist Hangman," a forbidden legend who hunted hundreds of dark wizards, was locked in the Forbidden Forest by Dumbledore himself. When the savior Harry enrolled in school, he tore open his cage and returned to the wizarding world as a professor. Dumbledore regarded him as a hidden danger, and the Ministry of Magic became his chess game, with death walking with him. When the sky of Hogwarts was set on fire, Lynch stepped out of the fire and smiled elegantly at Voldemort: "Hello, Tom, did you miss me?"

On the day he turned 11, Tom Riddle received his acceptance letter to Hogwarts, and his soul merged with a traveling soul from our world.

A new Tom Riddle is born, and he will take the wizarding world by storm.

With future knowledge and some creativity, he will achieve anything he sets his mind to.At the same time, he is also in the world of the Marvel Cinematic Universe/X-Men.

No harem, by the way

Matthew traveled to "Harry Potter", only to find that the world was facing the invasion of various foreign evil gods:

The "Dimensional Devil" that rules purgatory, the "Eyes of the Abyss" that dominate the spirit world, the "Paradox Devourer" that occupies the void...

There is also the "Blood Lord" who stole his chance to travel through time and whose strength has undergone a qualitative change...

There are suddenly many evil cults in the world. They are the root of the old beliefs and the anchor point for the invasion of foreign gods.

Fortunately, the system has awakened an incredible wisdom!

Yes, you read that right! The system has given itself a cheat code!

And as the host...Matthew can completely skip the comprehension steps and directly obtain the results of comprehension!

What does your understanding mean to my understanding? We just have different divisions of labor.

Many years later, when many evil gods were willing to burn the world to death in order to descend upon Hogwarts:

[You have come into contact with the origin of the laws of space. Due to your extraordinary understanding, you have gained the right to manage the crystal wall of the world.]

[You watched the world that was about to fall. Due to your extraordinary understanding, you mastered the endless world destruction chain.]

You can figure out the system, and leave Hogwarts to me!

Looking at the system prompt, Matthew announced domineeringly:

Evil God, get out of my Hogwarts!

…

Dumbledore: Wait, your what?

After traveling through the Harry Potter world for seventeen years, Whitefall, who could only use dark magic, was expelled from Hogwarts and became a Death Eater. He was later imprisoned in Azkaban for helping Voldemort.

With no other options left, he took out his wand and was about to commit suicide.

As he was about to die, he heard a golden light explode in his head.

[Ding, your Infinite Forbidden Spell System has been bound.]

No, I was already in Azkaban, and Goldfinger only came?

When he woke up again, he had returned to the scene seven years ago.

At that time, he had not yet entered Hogwarts and was surviving in the cracks of an orphanage.

With the help of the system, Bai Yun uses power far beyond black magic to reach the pinnacle of magic.

If he were to live his life over again, he would make the entire magical world submit to him!

"Auror? What does your arrest of dark wizards have to do with me, the Forbidden Spells Master?"

"Death Eaters? Do you think a mere Voldemort is worthy of my submission?"

"Defense Against the Dark Arts? Sorry, I was instantly killed by a forbidden spell!"

In this life, Bai Yun officially opens a new era of the magical world with his memory and golden finger!

Harry: It seems my classmates are more dangerous than Voldemort?

Dumbledore: Our house has opened Azkaban?

Voldemort: You are using my words!
