1 "My name is Neville Longbottom, I'm a fellow Hermione student and a classmate of the House, and I'm returning here from World Destruction Day 2025. William, in the face of you murderer, I can't suppress the desire to kill you. ”

The middle-aged man, Neville Longbottom, who had previously visited the Longbottoms at St. Mungo's Hospital. He stood up from the side of Young Gran and looked at William and said in a deep voice.

"Huh? Why do you all come here and say that about me? What murderer, what demon king who destroys the world? Why do you blame me for everything that will happen in the future? I still haven't done anything! ”

Originally, after William heard the middle-aged man in front of him say that he was Neville Longbottom, he began to think of that brave, kind, and lovely Gryffindor.

But when he heard that he was a murderer again, the resentment that had been suppressed in his heart rose again.

He's a 12-year-old kid, and he just wants everyone to be able to use magic, what's wrong with him. Why do these people who want to kill him call him a demon king, a world destroyer, and a murderer.

Why blame what will happen in the future on a child who has done nothing bad?

"That's why I didn't kill you. Dumbledore had taught me that no one could be born to determine whether he was a bad or a good person in the future.

William, sign a contract with me! Face me, swear that you will not destroy the wizarding world in the future, and you will not destroy this warm world. ”

Middle-aged Neville, he looked at William with deep eyes, and said to him in a low and heavy tone.

At the same time, he took out an empty four-centimeter-high crystal vial from his pocket, and then used his wand to cut a wound on his arm, allowing his blood to drip into the crystal vial.

This is a mutant blood pact similar to the blood pact between Dumbledore and Grindelwald, and both parties are not allowed to violate the content of the contract signed at that time until the blood pact is broken.

The middle-aged Neville knew that he had not spent much time in this world, and he could not teach William to change his ways and not become the murderer who destroyed the world.

He had always used Dumbledore as an example, but he couldn't go against his sense of justice, so he decided to use this method to prevent William from becoming the demon king.

"Why? You wizards keep assassinating me, and you won't let me destroy the wizarding world? And what's wrong with me just wanting to make magic accessible to everyone? ”

William looked at the half-vial of blood in the middle-aged Neville's hand, and he instantly thought of the blood alliance between Dumbledore and Grindelwald. Although it is unclear whether the contract of the middle-aged Neville is the same as the blood alliance, he knows that if he signs the contract, he will definitely fall into disadvantage if he meets the wizard who assassinated him in the future.

Even because of this contract, he is likely to let the great plan in his heart go to naught.

"William, who has been called a genius since childhood, you should understand that one, two, a small group of wizards does not represent all wizarding groups, nor does it represent the entire wizarding world.

Your sister, Hermione, will become the Minister of Magic in the future, and she will change the prejudice of wizards against Muggles and change the rotten system.

I believe that if you don't have the idea of wanting to ruin the wizarding world. You and your sister Hermione will work together to create a brilliant future for this world.

William, this pact will not make you my puppet, it will only prevent you from thinking of destroying the wizarding world and all of humanity in a fit of rage. It's the spiritual barrier that prevents you from destroying this world.

If a wizard wants to kill you, you can, of course, fight back. This is your freedom, and I will not limit yours.

William, you're Hermione's older brother. I don't think the good Hermione would have an evil brother. Everything that will happen in the future is just a choice that you have to choose.

I asked you to sign a contract with me, just to make sure that you were not swayed by anger and destroy your good heart.

Didn't you say you wanted everyone to use magic? Think about why you had this idea in the first place, and what do you want to do with it? ”

The middle-aged Neville saw William's angry face, he held back the anger in his heart and patiently explained.

There are seven billion people in this world, and each person is a different individual, both good and bad. A certain group cannot be labeled because of what it does.

Before he died, Dumbledore had spoken to Neville alone. As the most powerful wizard in this world, he also has a deep knowledge of prophecy.

When he was on the verge of death, he received a very vague prophecy.

In this prophecy, it is stated that after the death of the Dark Lord Voldemort, there will be another Dark Lord in this world, and this Dark Lord will be born among Muggles, and he will destroy the world.

No one could stop him, and even using the Time Shifting Device to go back in time to assassinate him would put him on the path of the Dark Lord faster and faster.

Dumbledore did not tell Harry and the others about this prophecy, believing that Neville, who had truly inherited Gryffindor's will, was the best candidate compared to Harry, who acted impulsively at times.

He met with Neville alone before he died, telling him to stop the birth of the Dark Lord.

But young Neville didn't understand any of this at the time, he thought that the Dark Lord was similar to Voldemort, as long as he stopped him before he destroyed the world.

Kona'i failed.

No matter what method he used, he couldn't stop William from activating the device that was destroying the magic of the world.

Since it can't be stopped, Neville, a middle-aged man who has witnessed the destruction of the world three times, decides to go back to 1991 and stop William's rise as an enemy.

He was ready to change William's mindset so that he would not develop the idea of being hostile to the wizarding world, and that he would not have the idea of destroying the magic of the world.

As an orthodox wizard, he looked up a lot of information about planeswalking. The same ending three times made him realize that the impact of each crossing was the cause of William's destruction of the world.

Time is a closed loop, and no matter how you change it, the ending is the same.

But there are still some differences, having already experienced three times after William destroyed the end of the world. The middle-aged Neville summed up a rule, that is, every time he crossed over to stop William, he would deepen William's determination to destroy the world.

The middle-aged Neville remembers that William's first destruction of the world was on November 25, 2036, in the winter of 2036, and he only killed all the wizards.

The second time the world was destroyed was on January 28, 2029, when William had the idea of eliminating the magic of the world and created the device to eliminate the magic power. But that one activation of the device only left those with magical talents and most wizards dead.

But for the third time, on September 19, 2025, William activated the device, but it caused the extinction of all living things in the world, and only a very small number of living things survived.
