Looking at Sirius's appearance, Ethan had a headache.

"What are you going to do in Hogwarts? Protect Harry? Hogwarts is safe! Isn't my protection enough?" Ethan said.

"I don't believe you." Sirius shook his head.

"Besides, Hogwarts is not safe. I have already investigated. Voldemort attacked Harry in the first year, and Voldemort's Basilisk attacked him in the second year."

"I was skeptical about the news that Voldemort was coming back to you before. I believe it now. I want to enter Hogwarts to protect Harry!" Sirius Black said seriously.

Ethan suddenly regretted taking Voldemort back to intimidate Sirius.

'If I had known this, I would have placed an Imperius Curse on him directly, which would have been easier.'

After some bargaining, Sirius was determined to go to Hogwarts. Otherwise, he would immediately turn himself in.

Ethan pinched his eyebrows helplessly, "Become a dog; follow me," Ethan said.

Ethan led Sirius, who turned into a dog, and soon came to the entrance of Knockturn Alley.

Today's Knockturn Alley has changed a lot. The streets with the cross-flow of sewage are gone, and they have become clean and tidy.

Those black magic shops also put away those strange decorations and put out some magic-sealed items.

There are no more dirty, eccentric wizards in fancy clothes on the street.

Lots of customarily dressed wizards walking up and down Knockturn Alley.

Knockturn Alley has become an ordinary wizarding street and is no different from its adjacent Diagon Alley.

Ethan walked through Diagon Alley with a dog and met many Aurors who greeted him.

No one doubted the dog beside him.

The Ministry of Magic agreed that the most likely place for Sirius to hide was Knockturn Alley.

Therefore, Knockturn Alley has already been plastered with Sirius's wanted posters, and many Auror patrols have been arranged.

Ethan brought Sirius to the dilapidated three-story building Snape had previously brought him.

Ethan pushed the door open, still like when he and Snape came here.

Walking down the creaking stairs, Ethan came to the broken door.

Ethan knocked on the door rhythmically, but there was no response from the door.

"Mundungus, don't let me knock a second time, or I'll send you to Azkaban!" Ethan yelled at the door.

"Coming! Coming!" Mundungus opened the door, smiling flatteringly at Ethan.

Mundungus has always had this reaction towards Ethan since he joined the Ministry of Magic.

"Mr. Ethan, are you here to get the armor? I've already done it for you!" Mundungus graciously handed Ethan a piece of armor.

A few days ago, Ethan found Mundungus and gave him the skin of the basilisk he had stripped. At the same time, he ordered a large piece of venomous horn hide from Mundungus.

Poison horn skin is very resistant to physical and magical damage and is a good material for armor. Unfortunately, the Ministry of Magic prohibits poison horn skin as a magic material.

It was incredibly troublesome to cure, and it required a lot of magic materials to complete.

Ethan wanted to make a set of armor with basilisk skin as the outer armor and poison horns as the inner lining, so he found Mundungus, who was very well-informed.

After Mundungus receives a deposit from Ethan, he will find a master who can make armor for Ethan.

Now, Ethan's armor is finally ready.

Ethan took out the armor from Mundungus' hands and looked at it in detail.

Then he took the dagger and slashed back and forth on the armor a few times, finding no traces.

Then he took out his wand and cast several offensive spells on the armor, but still did not cause any damage to the armor.

Ethan nodded with satisfaction. Mundungus is still very reliable in terms of reputation.

"Well done, I'll give you the money now," Ethan said.

Seeing Ethan satisfied, Mundungus breathed a sigh of relief.

"I have a little more help for you," Ethan said.

"Help me get some polyjuice potions. The more, the better."

"Okay, no problem," Mundungus said graciously. "When do you want it?"

"Right now," Eason said.

"Okay, no problem." Mundungus readily agreed.

"Just wait." Mundungus stood there awkwardly.

"I'll give you the money for the armor right now," Ethan said.

Then he threw a large bag of Galleons in front of Mundungus.

Mundungus hugged Galleons greedily, looking like he was too embarrassed by Ethan to count.

"Count them," Ethan said.

"No need, Mr. Ethan, I believe you," Mundungus said, but the expression on his face clearly showed that he wanted to count it right now.

"Count it," Ethan said.

Seeing that Ethan was not polite, Mundungus let go of himself.

He took out the piles of galleons and counted them carefully.

When Sirius saw Mundungus' greedy appearance, he whimpered in disdain and lay down at the door to rest.

After a while, Mundungus counted the money, "Exactly correct! Mr. Ethan!" Mundungus said excitedly.

"Just wait a while, and I'll help you get the potion."

Mundungus's short, plump body, which had acquired the galleons, showed far beyond his agility.

The man jumped out of the window.

Ethan and Sirius waited in the room alone for a long time.

When Ethan was a little impatient, Mundungus walked in with a load of jars.

He sat on the shabby bed panting.

"It's hard to find ready-made Polyjuice potions!" Mundungus said.

"Since Knockturn Alley was cleared, my business has gotten harder and harder," Mundungus complained casually.

Then he suddenly remembered that the man in front of him was the "culprit" who caused the changes in Knockturn Alley.

"Sorry, Mr. Ethan, I didn't mean to blame you," Mundungus explained stumblingly.

The reputation of "The Butcher of Knockturn Alley" was legendary in Knockturn Alley.

Ethan waved his hand to show that he didn't care about that.

"Who's appearance is this set to?" Ethan asked.

"A Finnish wizard with a smart head, no family, and even presumed dead," Mundungus introduced to Ethan.

"Here, the wizard's hair." Mundungus taught Ethan a package.

"Can you go out first? I want to experiment," Ethan said to Mundungus.

"No problem, no problem," Mundungus said, then went out and closed the door for Ethan kindly.

"Drink it!" Ethan shook the bottle in his hand.

The dog stood up from the ground and instantly turned into Sirius.

For Harry, Sirius would give everything, and without thinking, he raised the bottle and swallowed it.

"It tastes disgusting--" Sirius said with a dry cough.

But his appearance soon changed. First, his body was about to dissolve and gradually twist, and then he turned into a slightly plump middle-aged man with blond hair.

"It's weird like this."

Even his accent changed. Sirius looked at himself in the mirror, stroking his fat face and belly.

"The effect is good. Remember, you are now Jake, my assistant teacher for the Signs class!" Ethan said to Sirius Black.

"I'm going to write a letter to Headmaster Dumbledore asking him to agree to my recruitment of teaching assistants."

Only with this identity can Sirius successfully infiltrate the campus.

Satisfied with the potion's effect, Ethan called Mundungus in and threw him a bag of gold Galleons.

Mundungus reacted differently to the fact that there was one less dog and one more person in the room.

Ethan was pleased with Mundungus' performance as if seeing Sirius out of sight.

"Remember, you haven't seen me," Ethan instructed Mundungus before leaving.

"But I don't know you," Mundungus said with a smile.
