Kewen recounted the plot in the memory data, from the time Sirius sneaked into the castle to the end of the plot this year, without omission.

After listening, when Sirius Black looked at Kewen again, his eyes became very shocked.

Before, he also joked about whether Kewen had changed from a monster, but now, he has even been very doubtful that the joke will really be true by him.

Dumbledore, on the other hand, was in a good mood.

The plan that Cowen mentioned can not only allow Harry to grow up, but also allow him to find happiness that he can cherish for a lifetime from his predicament.

In addition, it is possible for Sirius Black, Lupin, and Snape to be redeemed from it.

The plan was so perfect that it seemed dangerous, but it didn't really allow anyone to get hurt.

But Dumbledore heard something.

That is, in the whole plan, there has been no shadow of Kewen's participation.

But after a brief thought, Dumbledore didn't care about this situation.

After all, he already felt very owed to Cowen, and it was too unfair for Cowen to always let Cowen help Harry so selflessly.

Thus, Dumbledore almost immediately identified the plan.

"Very good! Very good!" Dumbledore couldn't help raising his hands, clapping his palms up and down, and exclaiming: "It's wonderful! It's also a perfect plan! My son, thank you for this plan!"

"It's good to be able to help everyone." Kewen responded with a slightly reserved smile.

"So……"

Dumbledore waved his hand, causing the Marauder's Map on the desk to fly over, handing it over to Cowen and saying, "Next, I'll ask you to find a chance to give it to Harry."

"Ok sir."

Corvin responded and took the map from Dumbledore.

"It turned out to be..."

When Sirius Black saw the 'Marauder's Map', he couldn't help but say something with emotion.

Dumbledore was stunned for a moment, then asked, "You know this map too?"

"Yes sir." Sirius Blake stared at the map with complicated eyes, then shook his head slightly, sighing and said, "This was made by the four of us back then."

"The four of you..." Dumbledore recalled a little, gradually thinking of the situation back then.

Sirius Black did not notice Dumbledore's expression, but continued to stare at the map in Kewen's hand, and said with some nostalgia: "When the map was opened, among the four code names displayed first, I was the big one. Feet, Remus is the moon face, James is the prong..."

Speaking of which, Sirius's expression turned grim again, and he finally said through gritted teeth: "And that damn Peter! It's the wormtail shown above!"

Combining the memory and Sirius's remarks, Dumbledore has completely understood the situation, and he didn't say anything when he heard the words, but just nodded slowly.

On the other side, Kewen put his finger on the Marauder's Map, and then said softly, "The prank is over."

When the words fell, all the ink on the Marauder's Map quickly disappeared, and the entire map returned to plain parchment.

Putting away the map, Kewen looked at Sirius Black and hesitated.

The expression was too obvious, so Sirius asked suspiciously, "What?"

"Although it may be a bit rude." Kewen didn't hide anything, and asked directly: "I can see that this map uses a very high-end 'Tracking Charm' enchantment, and I can recognize 'Revelation Charm' and Illusions from it. I don't have any clue about the spells that make up the overall framework, other than the spells."

"So that's what you're asking about." Sirius was stunned, and then answered without concealment: "That's the 'contract curse' unique to our family."

"Of course." Sirius continued to introduce: "Actually, there are many other magic spells on it. In addition to the content, we also used a lot of magic spells to create this parchment."

"Oh?" Kewen was a little surprised. He took out the map and looked at it again. After a while, he confirmed to Sirius: "Is it the constant 'Recovery Charm' enchantment?"

"That's right." Sirius' expression seemed a little surprised again, surprised by Kewen's erudition, but immediately added: "There are other spells, but they are the complete set of spells that the wizarding world needs to make maps, of course. , in addition to these, there is a targeted spell on it."

"What is it?" Kewen couldn't help but ask.

"Yes..." Sirius was about to continue to tell Kewen unreservedly, but only uttered one word and stopped.

Looking at Dumbledore with some embarrassment, seeing Dumbledore's equally very interested look, Sirius said with a wry smile: "It's a spell specially aimed at Snape, which can make Snape unable to Discover the secrets of the map..."

Dumbledore was stunned for a moment, and then he shook his head wordlessly, without commenting.

Cowen didn't care about the so-called targeted spells, instead he was very interested in other spells that Sirius said.

The contract spell, and the matching spell for map making, Kewen's knowledge of these two aspects is still blank.

Therefore, the thirst for knowledge in his heart could not be suppressed, and regardless of whether it was rude, he immediately asked: "Can you teach me the 'contract spell' and the series of spells for map making?"

Sirius was stunned for a moment, probably the first time he saw someone so direct.

Dumbledore knew about Cowan's thirst for knowledge, so he immediately laughed 'hehe', and then explained it to Sirius Black on behalf of Cowan.

After explaining Kewen's attitude towards knowledge, Sirius Black became stunned.

Sirius is also a generous character, and Cowen is also considered his benefactor, so he nodded his head very generously: "Of course! Of course! After I deal with Peter, I will recover as you planned. If you're innocent, I'll go home immediately and bring those two books out to you."

"Thank you very much!" Kewen thanked expectantly.

Next, the three discussed the plan provided by Kewen in the office to prevent some unexpected situations as much as possible.

Kewen specially reminded that it is best to avoid the full moon day in the final closing, in case Professor Lupin turns into a werewolf in case of an accident.

Dumbledore and Sirius immediately took the reminder to heart.

For a while, they all ignored how Kewen knew that Professor Lupin was a werewolf.

But even if they think of this later, they will probably make up their own minds, thinking that with Kewen's erudition, it is natural to discover Lupin's identity...

It was not until halfway through the dinner time that the three of them supplemented the plan and discussed it. Dumbledore then entrusted Sirius to Kewen.

Saying goodbye to Dumbledore, Curwen took Sirius out of the office and then cast a Disillusionment Charm on him.

Taking Sirius out of the castle, Ke Wenming asked, "How did you get in and out of the academy before? Do you have any temporary accommodation?"

"The Beating Willow." Sirius Black made no secrets: "There is a tree hole under the Beating Willow. In fact, there is a secret passage inside. You can go to the 'Hogsmeade Village' through the secret passage."

"So it is." Kewen pretended to know just now, and asked again, "What about the residence?"

"For the time being, I live in a haunted house in Hogsmeade."

Sirius shook his head and sighed: "Although it is very old, it is always more comfortable than Azkaban. Before I successfully deal with Peter, nothing is so important to me!"

Hearing this, Ke Wen nodded to show understanding, and then said, "Then, you can follow my arrangement today."

"no problem!"

Sirius Black seemed to have a lot of trust in Cowan, perhaps saying that he completely trusted Dumbledore.

Since Dumbledore entrusted him to Cowen, he would also obey Cowen's arrangements.

Next, Cowen took Dumbledore's warrant and showed it to Filch, the gatekeeper, and left the academy with the invisible Sirius.

Back at the "Wonderful House" not far from the academy, Kewen did not let Sirius enter the house, but asked him to wait outside for a while.

As for the location of the house being known by Sirius, Kewen seemed very indifferent.

Anyway, the house has been placed on a 'secrecy spell'. Unless he is the owner of the house or Lili, who is the secrecy person, other people will not be able to enter the house even if they know that there is a house here, and they won't even be able to see it.

It didn't take long for Kewen to walk out with a suitcase, and in Sirius' eyes, it seemed like he appeared out of thin air.

Handing the suitcase to Sirius, Kewen explained: "This is a non-marking stretch box, I have prepared a full set of bedding for you, some tableware, and enough 'compound decoction' for you to use for two months. "

"Thank you, thank you child!" Sirius felt very warm-hearted for Kewen's assistance, and thanked him continuously while taking the suitcase.

Kewen went on to say, "I'll configure the 'compound decoction' for you in the academy, so you can use it for now to facilitate your activities around 'Hogsmeade Village'."

"Oh yes." Kewen put his hand into his pocket, took out a small bag, and handed it to Sirius again: "There are two hundred gold Galleons in it, which should be enough for you to use for a while, not enough to tell me again. ."

"Thank you..." Sirius' eyes were a little wet. This was the first time he felt warmth in twelve years. There were too many words to thank, but he couldn't say it for a while, so he could only repeat his thanks.

"At last."

Kewen took out another wand, holding it upside down and handing it out: "This is a wand that I...my niece made by herself. Although it's not a master craftsmanship, it can also be used. It's a combination of oak and unicorn tail hair."

Sirius looked a little flustered, and hurriedly bent down and placed the suitcase gently on the ground.

Then he raised his hands to pick up the wand, but after seeing his dirty fingers that looked like chicken feet, he hurriedly retracted his hands.

He kept rubbing on his clothes, as if he could wipe his hands clean, but in fact his clothes might be even more dirty.

Extending his hands again, Sirius took the wand cautiously, rubbed it for a while, then took a step back.

Leaning over and bending over, Sirius Black bowed deeply to Kewen, and the movement continued for a long time...
