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

Lupin guessed the reason.

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

But Sherlock stared at the map of live spots and said thoughtfully.

"Don't this map 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 when he sneaks into Hogwarts. Who in the school can keep staring at this map?"

What he said makes sense, but Sherlock always felt that there must be other reasons for his rejection of the proposal, but he did not delve into it, nodded and walked out of the castle with Lupin.

The moon had risen at this time, hanging in the air, emitting a bright light. Lupin's spirit had not changed much, but his face looked extremely pale under the moonlight.

Sherlock asked in confusion as he looked at his changes.

"Did you feel anything else before you transform?"

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

"The closer the time to transform, the more tired my body will feel. The fatigue of my body will lead to many high-level spells not being used, or the spells cannot be cast for a long time."

This Sherlock is understandable.

To be precise, the wizards in this world do not have blue bars. The magic power in the wizard's body represents the strength of magic. The stronger the magic power, the stronger the magic it uses, rather than a consuming energy.

If you have to give a blue bar feature to an attribute, it is more like physical strength.

Long-term casting will make the wizard exhausted and his physical strength will drop quickly. The students basically have no restrictions when practicing spells. They feel tired and can continue practicing after a while.

Theoretically, as long as a wizard has sufficient physical fitness, he can cast spells without limits.

This is also the reason why Sherlock has been persevering in training every morning. His floating wand casting system consumes a lot of energy.

If he uses two hundred and one magic wand together, he will be exhausted when he uses it three times. He can barely use it for the fourth time, but if he uses it five times, he will have to be exhausted and lying on the ground.

This is the effect of the curse being cut.

Overall, under normal casting, with Sherlock's physique, he can release spells between 500 and 600 times in succession, and his body will be hollowed out.

While the body is still developing and does not pay attention to exercise, Hogwarts students who usually cast about 200 spells will become tired, and 100 spells will feel tired.

But with the intensity of Hogwarts teaching, it is very rare for students to practice 100 spells a day, so learning magic is equivalent to no limit for them.

Moreover, for a normal wizard duel, it is usually possible that ten spells can determine the outcome. It is impossible for two people to shoot two or three hundred spells in a row, but the outcome has not been decided yet.

So there is no so-called blue bar in this world. As long as it can be used, you can throw the curse at will.

Except for Sherlock, an alien who can release two hundred curses at one time.

Sherlock has been studying the reasonable matching of the number of spells cast on the wand. Last time when facing the straw man, two hundred guardian spells were obviously too wasteful. Even if only one hundred shots were used, the same effect could be achieved if the combination was reasonable.

Two hundred laser rains flew out all over the sky, which seemed to be extremely deterrent, but it consumed Sherlock's endurance.

Lupin took Sherlock to the willow beside the forbidden forest. The willow tree was manic and aggressive, and normal people could not get close to it.

When he was more than ten meters away from the willow tree, Lupin waved his wand at a small stone beneath him.

The stone suddenly turned into a squeaking mouse, running quickly and rushed to the trunk of the willow to hit the willow.

It seemed as if it had touched a knot on the trunk of the willow tree, and the irritable magic willow tree immediately stopped moving.

Lupin took Sherlock to find an authentic entrance next to the tree canopy, and the two climbed in together.

"This willow planted by Dumbledore in the year I entered school, and the secret passage here was specially prepared for me. When I was in school, every time I transformed, he would ask the school doctor Mrs. Pomfrey to take me here, and then go from this secret passage to the screaming shed in Hogsmeade village, where I transformed and spent the time to become a werewolf, so as not to hurt others."

Lupin told Sherlock about his past experiences.

Sherlock could clearly hear that his words were a little emotional, and he seemed to want to hide it, but he could not hide the loneliness.

He didn't ask much about this. Everyone has their own little secrets, even he himself is no exception.

They walked in the passage for about half an hour and finally arrived at a dirty and dilapidated shack.

This is Hogsmeade Village, or the famous haunted house in the entire British magic world - the Screaming Shed.

Sherlock looked at the house and recalled the time when the name of the screaming shed was circulated, and probably guessed some things.

"This place is called a haunted house because someone used to hear strange screams in the middle of the night. That's the movement that came out after you transformed here when you were a student?"

Lupin nodded.

"Yes, in fact, the spread of rumors was also the effect of Professor Dumbledore's intentional fueling, so that no one would risk entering here when I transformed and be injured by me."

"But actually one time it was still a little bit late?" Sherlock blinked.

Lupin looked at him in surprise.

"You, do you know these things?"

"Snape told me." Sherlock sighed, "I asked him why he hated you so much. He told me it was because when you transformed, your friend tricked him into it and was almost bitten to death by you who turned a werewolf."

Lupin fell silent, his expression of hatred was bleak, as if he was recalling some bad memories.

"We did too much because we were ignorant at that time, especially Sirius."

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

"Who did you say!"

Lupin seemed to have missed his mouth accidentally, but he didn't care much about letting Sherlock know about this, but just as he was about to open his mouth, his face suddenly became ferocious!

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

Sherlock also discovered that Lupin was preparing for transformation. He took a few steps back to ensure that he had enough casting distance after an accident, and observed Lupin's performance when the werewolf transformed.

A painful roar sounded, Lupin's head was stretching and his body grew longer.

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

An upright werewolf image appeared in front of Sherlock. Compared with ordinary wolves, the werewolf in the animal form had a shorter mouth and nose, a slightly smaller pupil, and looked closer to humans, but the combination of human figure and wolf appearance made the werewolf look extremely ugly.

After turning into a werewolf, Lupin stared at Sherlock with the eyes of the wild beasts, but there was no tyranny or cruelty inside, only a calmness.

Obviously this was the effect of him drinking wolf poison in advance.

Studying the transformation of werewolf was the main purpose of Sherlock and Lupin coming together, but now he no longer had this intention and asked in Lupin's eyes.

"You said that my friend during school was Sirius Black?"

Lupin, covered in gray-black hair, signaled Sherlock to sit down and said, "None of them cared about the dusty floor of the 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 gentleness unique to his tone. "So you will know some things even if I don't tell you now."

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

"Dumbledore was a kind principal. After knowing that I was a werewolf, he still specially approved me to study in Hogwarts. Here I not only learned magic, but also made some good friends."

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

"But the identity of werewolf did not become an obstacle to our friendship. They were still willing to get along with me. Later, they learned difficult deformation techniques for me and prevented me from transforming alone here."

Hearing this, Sherlock certainly guessed who Lupin had when he was in school.

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

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

"Before school started, Mr. Weasley found me and told me about Black's betrayal of Harry's father. I know that they were good friends before. Since you have Black among your friends, there will naturally be Harry's father."

Lupin nodded and admitted, his eyes mixed with pain.

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

"Peteor Peter?"

Another familiar name, not only did Mr. Weasley talk to him in the Break Cauldron Bar, Sherlock always felt that he had seen or heard of the name accidentally, but he could not remember it.
