While Bell and his sister were cleaning up the delicacies at the banquet, our little savior Harry was about to have his own magnificent adventure once again.

After the sumptuous Christmas dinner, Harry, Ron, and Neville returned to the Gryffindor common room.

Not many young wizards chose to stay at Hogwarts for Christmas, and soon, only the three Harrys were left in the lounge.

Ron and Neville were playing wizard chess, while Harry looked out the window at the night, feeling a little lost.

He was grateful that Ron and Neville were willing to stay and spend Christmas with him.

However, although it was bad to say this, he still wanted to enjoy Christmas happily and warmly with his parents.

Shaking his head, Harry decided to find something to do to distract himself.

After thinking about it, Harry ran back to the dormitory and got the Marauder's Map that George and Fred had given him before.

"Hey! Harry. What do you want with it?"

Ron looked at the parchment in Harry's hand curiously.

As Harry's good brother, of course he knew what it was.

At first, he was mentally unbalanced for a long time because of this. After all, George and Fred were his brothers. As a result, the two of them did not give him such a fun thing, but chose to give it to Harry.

But then I thought about it, he and Harry had such a good relationship, didn't Harry's things also belong to him? Not bad.

Neville also noticed the Marauder's Map in Harry's hand.

He became a little nervous.

His 'herbivore' instinct told him that nothing good would happen next.

"I'm not doing anything, I'm just a little bored."

Harry casually unfolded the parchment in his hand.

He pressed his wand against it.

"I solemnly swear that I have done nothing wrong!"

After the curse, black lines appeared on the Marauder's Map.

This is a map of the entire Hogwarts.

If you look carefully, you can find a few small black dots scattered among the black lines. This is the one who stays in Hogwarts.

Since most people have left Hogwarts, only a few scattered black dots remain now.

Harry looked at the names above the little black dots one by one. He wanted to know, besides the three of him, who else were unlucky enough to have to stay in Hogwarts on such an important day as Christmas?

This was the way Harry came up with to kill boring time and distract his attention.

"Hey! Guys! Come on over and see what I found!"

Harry suddenly exclaimed loudly.

Ron and Neville immediately stopped what they were doing. Although the smile on Harry's face made the two of them feel a little uneasy, they quickly came to Harry's side.

"what have you found?"

Ron asked curiously.

He had rarely seen Harry so excited. If he remembered correctly, the last time was when Harry was elected Seeker.

"Here! Look, this person's name!"

Hearing this, Ron and Neville looked at the black spot at the tip of Harry's finger. The name above the black dot made the two of them hold their breath immediately.

"Sirius Black!?"

Ron exclaimed in disbelief.

He only knew one person with that name. That was the man who had been making a lot of noise recently, the escaped convict from Azkaban, who intended to sneak into Hogwarts and kill Harry.

"C-could it be the same name?"

Neville stammered words that he didn't even believe.

When he saw this name, he subconsciously wanted to escape.

A cruel and murderous demon is lurking not far from them. This is too scary!

"No! There is no way that anyone would stay on the edge of the Forbidden Forest at this time! So this must be that Sirius Black! The bastard who killed my parents and now wants to kill me!"

Harry said through gritted teeth.

"We must report this to the professor immediately! Black might run away if it's too late!"

With that said, Ron planned to run out of the lounge.

"No!"

Harry grabbed Ron's arm.

"We'll go ourselves!"

"What!? Are you crazy!?"

Ron looked at Harry in disbelief.

Harry at this moment felt so strange to him.

"Yes, yes, Harry. Black is an adult wizard, and he is also a vicious murderer. We, we will not be his opponent."

Neville was also trying his best to persuade Harry.

He would rather spend a day in a room with Snape than find that Black guy.

"We have an invisibility cloak that allows us to get close to Blake without anyone noticing, and then launch a surprise attack! The most important thing is, we also have this!"

With that said, Harry took out a necklace from his collar.

"This is a defensive accessory I bought not long ago. Malfoy's previous defensive accessory blocked Buckbeak's attack for so long without being broken.

When you find Blake later, you will stand behind me and attack him. We can definitely win! "

"But, Blake may also have..."

"impossible!"

Harry interrupted Ron.

"Don't forget, he is a wanted criminal and he has no way of going to the store to buy anything."

It seemed that although Harry was angry, he did not completely lose his mind. At least he made what he thought was a complete preparation.

"But, I still think we should tell the professor. What if we fail to catch Blake and let him run away again? In that case, Blake will definitely be more cautious in the future."

Even if Harry tells the truth, Neville will not change his opinion.

He really doesn't want to go to Blake!

"Blake killed my parents!"

Harry growled and looked at Neville.

"I must punish him with my own hands!"

Seeing that Neville was frightened by him and took two steps back, Harry took a deep breath.

He realized that his emotions were a little out of control. His anger should only be directed at that damn Black, not his friends.

"Please, Ron and Neville. This is my life's request. Don't tell the professor, at least not now. You can look at the Marauder's Map here. If I fail, you can go find the professor immediately."

After saying that, Harry turned around and walked towards the dormitory.

He was going to take out the invisibility cloak his father left for him.

There is nothing more suitable than using his father's relics to avenge his parents.

Seeing Harry's decisive back, as if he was about to disappear forever, Ron and Neville looked at each other and chased after him in unison.

"Don't stop me!"

Harry said firmly as he looked at the two friends who were catching up.

"Of course. But we can't let you go alone."

Ron shrugged, trying to sound as relaxed as possible.

"Don't forget, man, we are a team. We defeated the trolls together, guarded the Magic Stone together, and drove away the Acromantula together. As long as the three of us work together, just one Black can't be us. of my opponent.”
