Hermione didn't even ask Carl what she had done that day, and after taking revenge on Carl, she seemed to have forgotten about it.

However, she has not forgotten her promise, and in order to prevent Carl from taking the initiative to deduct points again, she has been keeping an eye on Carl.

This one was nothing, Carl would run to the library as soon as he didn't have class, and Hermione did the same, and after forming a habit, the two began to go together instead.

Especially when Hermione learned that Carl had memorized almost all the titles of the books in the Hogwarts Library, she simply used Carl as a human flesh searcher.

"Carl, where can I find the Reverse Charm?" Hermione asked as she stood in front of the bookshelf, her eyes searching up and down.

"Standard Spells: Level 3, Chapter 8. Karl sat at the reading table next to him, flipping through the books boredly as he replied casually.

This standard question-and-answer method has almost become a daily routine for two people.

In any case, the two of them are the only people in Hogwarts who can learn a common language.

This stunned Harry and Ron, who had no idea that Hermione, who had always been nosy, would find a friend.

Since she often went to the library with Carl, Hermione didn't care much about their breaking of school rules.

In fact, Hermione doesn't care much about the two of them at all now.

Everything went on uneventfully until one day in late October, when Carl finally ended his confinement with Professor McGonagall.

At the same time, on this day, when Hagrid was making a routine inspection of the Forbidden Forest, he discovered an extremely strange thing.

The tail hair of a unicorn in the Forbidden Forest turned bald for some unknown reason.

When Professor McGonagall learned of this, she immediately stepped up the school's security, suspecting that some dangerous magical creature had entered the Forbidden Forest.

Therefore, in the morning class of the next few days, she repeatedly strictly forbade students from entering the Forbidden Forest, and George and Fred received her special attention.

All of this is, of course, Karl's handiwork.

Finally caught a unicorn, how could he just take a little blood and leave, with his character of plucking the feathers of geese, the unicorn tail hair of ten gallons is naturally his must-have.

If it weren't for the fact that the unicorn wagged its almost bald tail and kept pretending to be pitiful to him, he would have cut off its horns, and that was the real thing.

It took a lot of effort for Carl to refrain from doing so.

......

In the blink of an eye, the time is Wednesday again.

After less than a month at the school, Dumbledore left again.

Today is October 30th, 1991, Wednesday, and the day after tomorrow is Halloween.

At eleven o'clock in the evening, Carl showed up at the Room of Need.

He even had some anticipation of what Voldemort would teach him this time.

However, as soon as he entered the house, the latter did not guide him as he had done last time.

"Carl, I think we can go one step further in helping each other. ”

Here it comes!

Karl thought to himself, he had already guessed that Voldemort would do this, but he didn't expect it to come so suddenly.

"This year, there's one thing hidden in this school, Carl. Something that would have freed me from the way I am now, you should have heard its name, and I think you've even guessed what it is. ”

"Philosopher's Stone. Carl whispered.

Voldemort grinned, "Yes, Karl, the Philosopher's Stone!"

"It can make people immortal, and it can turn any metal into gold, it's strange that this one behind it was taken out by people and said, they actually think that gold can be comparable to immortality, what a bunch of fools!"

Carl nodded subconsciously.

Deep down, he agreed with Voldemort's statement.

Voldemort smiled with satisfaction at Karl's reaction and continued, "Gold, just a by-product of the elixir, just like the magic I taught you, the Philosopher's Stone can change the nature of matter, from a deeper level than that magic. ”

Karl jaw.

Voldemort's magic was very clever, but it was far from the Philosopher's Stone.

"Theoretically, the Philosopher's Stone can be used to synthesize anything, and that's the essence of its ability to make elixirs, but these idiots don't even understand that. ”

Karl nodded again, he had already guessed about the role of the Philosopher's Stone, and Voldemort's statement coincided with his guess.

"I want you to help me get it, Carl. ”

Karl was about to continue nodding his head, when he came back to his senses.

Nima!

Voldemort's demagogic methods are truly unguardable.

Voldemort didn't plot against him, so he didn't break his oath.

It's just a verbal demagoguery, plus some tiny spells that set off the atmosphere.

He didn't even need a wand, not even magic at all, just a simple application of magic that Voldemort could use in his current state.

It's extremely simple, but it works just right.

Carl rubbed his eyebrows, if it weren't for his achievements in the direction of Occlumency, he would have been fooled into finding the north.

He made a vow with Voldemort to give once in return for an equal amount.

The pact was there, starting with the unbreakable oath he and Voldemort had established, and their every word was bound by the oath.

As long as he nodded, it was a yes, and the oath between him and Voldemort would be valid again.

Of course, according to the contract, even if Voldemort didn't say it, as long as Karl helped him do it, he would have to pay the equivalent in exchange.

Sighing secretly, he could do something for Voldemort in exchange for the knowledge he wanted, but help him steal the Philosopher's Stone-

"Carl, I just need the Philosopher's Stone to recreate a new body, and after that, the Philosopher's Stone will be yours!

Nima!

Carl's heart stopped beating for a few seconds, and his head was buzzing.

He was about to refuse, but the temptation was too great.

Philosopher's Stone, that's not a big deal, Voldemort is willing to give up, that's because he already has a Horcrux, and the Philosopher's Stone is just a prop for him to restore his body, and after using it, it will naturally be useless.

But for Carl, it's a treasure that is absolutely hard to describe in words.

What's more, there's Voldemort's lifelong knowledge, which is truly priceless.

Voldemort had already given the exchange, and at the same time made a request, and as soon as he nodded, the contract was immediately established.

No one will be able to turn back then, as long as he gets the Philosopher's Stone and gives it to Voldemort, he can directly obtain the two things he has always dreamed of.

Immortality and unparalleled power.

What should he do?

Yes, or no?
