Remove the spell.

The effect of a very simple first-order spell is to shield the external magic residues attached to the body, so that the subsequent study and research of the spell can be more smooth, eliminating external interference, similar to disinfecting before entering the laboratory.

Of course, there are no magicians who actually do that.

The error caused by the faint external magic is almost negligible, and Melvin is the only one who has such mandatory requirements for his "students" internally.

As Liao Yu, who has been with Marvin for a long time in the game, this rule can be regarded as natural.

"Teacher, you should have noticed it, the threat of the demons is approaching."

After entering the house, Liao Yu got straight to the point.

Melvin seemed to have already tacitly understood something, he nodded, did not hide or hide from Liao Yu at all, but nodded seriously:

"Yes, and the process of the arrival of the demons is still speeding up, I just communicated with the great elder of the elf clan a few days ago, and Nassi told me that it is because in our world, there is an object that makes the demons feel threatened, so it caused their speed."

"For the sake of humanity and the world, and to pay for my mistakes, I must find this last hope, but now it seems, well, that 'hope' took the initiative to find me first, and I'm really ashamed."

Melvin shook his head with emotion.

"I know you must have a lot of confusion in your heart right now, but before that, can I ask you a question?"

"Of course."

After that, Liao Yu got up and didn't ask directly, but looked left and right in the room, as if he was looking for something.

Soon his eyes lit up and he found the target.

It was a black dumpling lying lazily on the balcony.

"Meow, come, meow, come over here."

With Liao Yu's voice, the black ball on the balcony raised his head, it turned out to be a slightly obese big black cat, and now this black cat was staring at Liao Yu a little strangely.

It was strange to Liao Yu, but the stranger called out his name.

After hesitating for a few moments, the big black cat jumped down from the balcony and came to Liao Yu's feet.

"Really good, I'll borrow you for the time being."

Liao Yu picked up the black cat and put it on the experimental table.

Next, Liao Yucai turned his head to look at Melvin again, and began his question: "Teacher, let's assume a future, when you taught me the musket technique, I forgot to cast the "Spell Eliminator" before entering the house, and as a result, that little bit of external magic impurities interfered with the spell, causing the musket technique to get out of control and kill Woo Meow. ”

"I know that you like Meow very much, teacher, as family, so if you are given a chance to go back to the past, how can you save Meow?"

Melvin didn't pay much attention to the slightly whimsical and abrupt question raised by Liao Yu.

Instead, I thought about it and treated it as if it were a single issue.

"I think the easiest way to do this is to remind you before you enter the house, so that you can cast the "curse" well, and then history will be rewritten."

"But I guess. It's definitely not that simple, right? ”

"Yes, because I still have one condition that I haven't said, in the future I hypothesized before, it was precisely because of the death of Woo Meow that I, as a disciple, was extremely repentant, which stimulated my potential, so that I could repent from now on, and be extremely rigorous in my future magic practice, and it was this rigor that saved my life in the fight against a certain enemy in the future."

"If you add this condition, how else would you revise history?"

This time, Melvin's thinking time has become noticeably longer.

Even his brows furrowed slightly.

Very simple.

The previous future was very simple, it was a student mistake that caused the death of a black cat.

But that's no longer the case.

The death of the black cat taught the students a lesson, and it was this lesson that allowed the students to be rescued in the future.

In other words

This becomes a "either/or" dilemma.

If you really modify the future of "Black Cat Death".

Then it will inevitably lead to students not being taught.

Indirectly let students die in the future battle with a strong enemy, because of this lack of "caution".

This is the butterfly effect.

It may seem like a revision of history, but it will involve an infinite number of other future changes.

Melvin had to admit.

It's a really difficult question.

But

Since he is a "teacher", how can he be asked by students?

Melvin smiled.

The previous frown has long since disappeared.

He already has an understanding of the law.

It's not hard either.

As long as the black cat is both dead and not dead.

Melvin quickly found an empty cardboard box from the side.

afterwards

Put this cardboard box on the black cat's body.

The carton is not transparent.

Liao Yu couldn't see the inside at all from the outside.

It can only be judged from the "meow" sound made by the black cat inside the cardboard box, and the black cat is "in".

Later, Melvin raised a flame in his right hand and threw it at the box covered with the black cat.

Rumble!

The flames devoured the cardboard box in one fell swoop.

Wait for the flames to go out.

Only ashes remained at the scene.

It seems that the black cat and the cardboard box were tragically burned.

So it goes.

The history of the black cat's death is achieved.

At least from the perspective of Liao Yu, a "witness".

However.

"Meow?"

The black cat, which should have been burned in the cardboard box, now poked its head out from behind Melvin and let out a cry of confusion.

It turned out that in the cardboard box, Melvin had already set up an extra hidden teleportation to send the black cat out in advance.

After doing all this, Melvin stretched out his hand to Liao Yu.

"In this way, history has been revised, in the eyes of my apprentice, the black cat is still dead, he will still learn a lesson, and in the future he will defeat the enemy because of this, but at the same time, the black cat has also survived, but."

However, the black cat has to disappear forever, maintaining its state of "suspended animation" in the eyes of witnesses, until its influence disappears before it can be "resurrected". ”

"Worthy of a teacher."

Liao Yu applauded and sighed from the bottom of his heart.

It took him a long time to figure out the method from the laws of the Philosopher's Stone, and as a result, Melvin thought for a while before he quickly had an epiphany.

It's a pity that the teacher is still a little worse.

"If you let the black cat disappear like this, there will be a great risk, and it will really drown in the long river of history, just like people have two deaths, one is a physical death, and the other is when everyone forgets you."

"So for the sake of insurance, the black cat also needs to have witnesses that belong to it, and the more the better."

Liao Yu said as he cast a "transfiguration" spell on the black cat.

Soon this black dumpling turned into a small white dumpling.

Not only the hair turned white.

The age has also become younger.

Although you can vaguely see the shadow of the black cat when you grow up, if you don't specially investigate and identify it, you will almost not be able to recognize it.

"I will let this cute little white cat participate in the beauty pageant, so that all the audience will remember such a beautiful kitten."

"In this way, history can be regarded as a complete revision."

"The original history was that the student blew up the black cat by mistake, and the student felt guilty for a lifetime, and in the future because of this lesson, he won from a strong enemy."

The current history is that the student "blew up" the black cat, and felt guilty for a lifetime, and defeated the strong enemy in the future, but suddenly one day, when he returned to the laboratory of the year, he found clues to the spider traces, and realized that the black cat might not be dead. ”

So he immediately followed the "clues" to pursue the black cat, and found that the white cat in the beauty pageant that year was the black cat, and finally he successfully found the white cat, and lifted the illusion on the white cat, a happy ending.

Liao Yu, the last, walked to a world map hanging on the wall of the room.

"Teacher, I now want to use your power to leave a clue for that future student."

Liao Yu identified the location of the map.

Found somewhere in a thousand years.

Later, Liao Yu looked at the pile of miscellaneous books next to the map.

The teacher loves to read all kinds of books.

The three books on the top stack are Icarus' Fall (), Exploit and Be Used: The Balance Between Magic and Sorcerers (Reference Book), and . The Price of Promises (Philosophy Book)

Liao Yu: "Teacher, I hope that in this position, a country will appear. ”

"As for the name of the country, you can name it."

Melvin nodded.

He also saw the three closest books that he was next to the map.

So, Melvin simply combines the first words of the first words of these three books.

"I see, let's call it Illinois."
