"That's probably the two brothers from the Weasleys. Seeing that Harry couldn't go to Hogsmeade this year, they gave him this map."

Lupin guessed why.

He said, got up from the chair, put on his coat, and prepared to go out.

Sherlock stared at the Marauder's map and said thoughtfully.

"Isn't this map able to see the movements of everyone in Hogwarts? Maybe we can find Black through this."

Lupin shook his head.

"Hogwarts is very big, and there is a lot of information on this map. Let's not talk about whether we can find Black on the map the first time he sneaks into Hogwarts, who in the school can always have it?" Time to stare at this map?"

What he said made a lot of sense, but Sherlock always felt that there must be other reasons for him to reject this proposal, but he didn't go into it, nodded, and followed Lupin out of the castle.

At this time, the moon had already risen, hanging in the air, emitting a bright white brilliance. Lupin's spirit had not changed, but his face was extremely pale in the moonlight.

Looking at his change, Sherlock asked suspiciously.

"Before you transformed, didn't you have any other feelings?"

Apart from the excessively pale face, Lupin's emotional and mental performance was fairly normal, he explained.

"The closer it is to transform, the more tired my body will feel. The fatigue of my body will cause many high-level magic spells to be unable to be used, or unable to cast spells for a long time."

This Sherlock is understandable.

To be precise, the wizards in this world do not have blue bars. The magic in the wizard's body is more like a representation of the strength of magic. The stronger the magic, the stronger the magic used, rather than a consuming energy.

If you really want to give an attribute a blue bar feature, it's more like physical strength.

Long-term spellcasting will make the wizards exhausted, and their physical strength will drop rapidly. Students basically have no restrictions when practicing magic spells. They can continue to practice if they feel tired and rest for a while.

In theory, as long as a wizard's physical fitness is sufficient, he can cast spells without limit.

This is also the reason why Sherlock keeps getting up and exercising every morning. His floating wand casting system consumes a lot of energy.

Two hundred and one magic wands were cast together. He used it three times, and his body would be exhausted. The fourth time he could barely use it, he had to lie on the ground directly tired.

This is still the effect after the spell has been reduced.

To sum up, in the case of regular spell casting, with Sherlock's physique, he can already cast five to six hundred consecutive spells, and his body will be hollowed out.

And while the body is still developing, Hogwarts students who don't usually pay attention to exercise will get tired when they normally cast about 200 rounds, and feel tired after 100 rounds.

However, with the intensity of Hogwarts teaching, it is rare for students to practice a hundred spells a day, so learning magic is equivalent to no limit for them.

And for a normal wizard's duel, it usually takes ten spells to decide the outcome. It is impossible for two people to shoot two or three hundred spells against each other in a row, and the outcome has not yet been determined.

Therefore, in this world, there is no such thing as a blue bar. As long as you can use it, you can cast the spell at will.

Except for Sherlock, who can unleash 200 spells at a time.

Sherlock has been researching a reasonable combination of the number of spells cast on his wand. Last time he faced a straw man, 200 Patronus Charms was obviously too wasteful. , the same effect can be achieved.

Two hundred laser beams flew out all over the sky. It seemed to have a strong deterrent effect, but it consumed Sherlock's stamina.

Lupin took Sherlock to the beating willow next to the Forbidden Forest. The willow tree was manic and aggressive, and there was no way for normal people to approach it.

When he was still more than ten meters away from the willow tree, Lupin waved his wand at a pebble under him.

The stone suddenly turned into a squeaky mouse, running fast, and dashing to the trunk of the beater willow.

It seemed to have touched a knot in the trunk of the willow tree, and the irascible magic willow tree came to a standstill.

Lupin led Sherlock to find an authentic entrance beside the canopy, and the two climbed in together.

"This beating willow was planted by Dumbledore in the year I entered school, and he specially prepared the secret passage here for me. When I was in school, every time it came to transform, he would Let the school doctor Madam Pomfrey take me here, and then let me go from this secret passage to the screaming shack in Hogsmeade Village, where I transform into a werewolf, so as not to hurt others."

Lupin tells Sherlock about his past experiences.

Sherlock can clearly hear it, and his words can be a little emotional, and some seem to want to hide, but can't hide the loneliness.

He didn't ask much about this. Everyone has their own little secrets, even himself.

They advanced in the passage for about half an hour, and finally came to a dirty and dilapidated shack.

This is the village of Hogsmeade, or the famous haunted house in the British wizarding world - the Screaming Shack.

Sherlock looked at the house and thought of the time when the name of the haunted house, The Shrieking Shack, was spread, and probably guessed something.

"It's called a haunted house because someone always heard strange noises in the middle of the night. That's what happened after you transformed here as a student, right?"

Lupin nodded.

"Yes, in fact, the spread of rumors is also the effect of Professor Dumbledore's deliberate promotion, so that no one will venture into this place when I transform and be accidentally injured by me."

"But actually it was almost once?" Sherlock blinked.

Lupin looked at him in amazement.

"You, do you know these things?"

"Snape told me." Sherlock sighed, "I asked him why he hated you so much, and he told me it was because when you were transforming, your friend tricked him into it and almost got transformed. You who became a werewolf will be bitten to death."

Lupin fell silent, his expression was bleak, as if he was recalling some bad memory.

"At that time, we really did a lot because we were ignorant, especially Sirius."

Sherlock was stunned when he heard this familiar name, and then he reacted immediately.

"Who are you talking about!"

Lupin seemed to have accidentally said something, but he didn't care much about letting Sherlock know about it, but just when he was about to open his mouth, his face suddenly turned hideous!

"Wait, wait, let me tell you, Sherlock..."

Sherlock also found that Lupin was about to transform into a precursor. He took a few steps back to ensure that he had enough casting distance after an accident, while observing Lupin's performance when he transformed into a werewolf.

A painful roar sounded, Lupin's head lengthened and his body lengthened.

His shoulders were arched, hair grew on his face and hands, and his fingers were bent into claws.

An upright image of a werewolf appeared in front of Sherlock. Compared with ordinary wolves, the animal-shaped werewolf had a slightly shorter snout and smaller pupils, and looked closer to a human, but the combination of the human body and the wolf's appearance, Make the werewolf look very ugly.

After transforming into a werewolf, Lupin stared at Sherlock with the eyes of those beasts, but there was no tyranny or cruelty in it, only peace.

Obviously, this is the effect of his drinking the wolf poison potion in advance.

Studying the transformation of a werewolf was the main purpose of Sherlock and Lupin coming together, but now he has no such thoughts, and asked Lupin's eyes instead.

"You said your friend in school was Sirius Black?"

Lupin, who was covered in gray-black hair, motioned Sherlock to sit down and said that none of them paid any attention to the dusty floor of the Shrieking Shack, and sat directly on the ground.

"I got the news that you joined the Order of the Phoenix last year, Sherlock." Lupin's voice in the werewolf state was rough and low, but still had the characteristic gentleness in his tone, "So there are some things I don't know now. I'll tell you, and you'll find out later."

Sherlock didn't say anything, he quietly listened to Lupin telling his story.

"Dumbledore is a benevolent headmaster. After knowing that I was a werewolf, he still specially approved me to enter Hogwarts. Here I not only learned magic, but also made some good friends. ."

"I've always been afraid that if they found out that I was a werewolf, they would alienate me because of this, but later they discovered my secret through clues."

"But the identity of the werewolf did not hinder our friendship. They were still willing to get along with me. Later, they learned the difficult Transfiguration for me, so that I would not be transformed here alone."

Hearing this, Sherlock of course guessed who Lupin's school friends were.

"So Sirius Black, James Potter, they are all your friends?"

"How did you know there was James?" Lupin asked in surprise.

"Mr. Weasley specifically found me before school started and told me about the story of Blake's betrayal of Harry's father. I know they were very good friends before, and since you have Blake among your friends, naturally there will be Ha Lee's father."

Lupin nodded and admitted, his eyes mixed with pain.

"Sirius, James and Pettigrew, they are all my friends."

"Peter Pettigrew?"

Another familiar name. Not only was Mr. Weasley mentioned to him in the Leaky Cauldron, Sherlock always felt like he had seen or heard this name by accident somewhere, but never thought of it. stand up.

"Yes, Pettigrew Peter, we were a group at the time, but you should know what happened later. Black betrayed James, causing him and Lily to be killed, and then Peter wanted to stop Black for revenge, and was also used by him. Only one finger was left in the curse!"
