Snape remembered clearly that he was still under the Disillusionment Charm.

At this time, pretending to be air is the first, most appropriate and suitable choice for normal people and fools who are not so stupid.

"Stop pretending." Harry raised his wand. "I can smell the grease on your hair from all over Gryffindor Tower."

Snape's face fell.

This was not planned.

Shouldn't it smell like potion?

"Stop the spell." Harry whispered.

Snape held the wand under his robes, and used the magic power in his body to resist Harry's spell.

Like ice melting away, the power of the Disillusionment Spell was gradually dissipated.

The eraser was smeared on the paper, and Snape's figure was painted out with a click.

His heart seemed to melt away, and ripples appeared.

Three years ago, in that summer, he didn't have such a huge magic power. But now, his magic power has surpassed his own. Snape was in a trance. In a blink of an eye, it was really just a blink of an eye. Potter was already sixteen years old, and he would become an adult in half a year - wizards became adults at the age of 17.

In terms of magic power, the 17-year-old wizard's magic power will be completely stable.

Mentally speaking, this age is just right. It is the time to overcome the immaturity of adolescence and begin to have a clear understanding of the world and to have a self-image.

Lily is only two years away from getting married.

He was in a trance.

The Disillusionment Spell was completely broken.

"Professor Snape." Harry hid his inner doubts and questioned in a cold tone.

With Snape's magic power, he shouldn't have been able to break the curse so quickly.

"Potter, I remember it's curfew now." Snape looked very unhappy. "The restless Gryffindor has started to wander at night again. Potter will be deducted ten points for violating school rules."

"Before the professor deducts points from me, I want to know why the professor is here?" Harry stared at him without changing his tone. "I remember the seventh floor, the eighth floor, and the Gryffindor Tower. Currently, no one except Gryffindor students and Professor McGonagall is allowed to enter."

"Professor Snape, you shouldn't be here."

Snape said nothing.

Harry leaned over and looked behind him: "Also, what's with this door?"

Snape took a deep breath and said softly, "I heard a rumor from the Slytherin students that there is a hidden chamber on the eighth floor, so I came to take a look."

"Really? But why not just tell Professor Dumbledore." Harry looked at him calmly and took a few steps forward.

Snape narrowed his eyes: "I have to confirm whether it is true news."

"After all, Slytherins don't often appear in Gryffindor Tower."

Harry continued to look past him and at the door handle on the wall. It had not been touched for a long time, and even because of Snape's inner thoughts, it was fading a little bit: "Then it is confirmed to be true now."

"Professor, you don't have to be so sneaky."

Snape said nothing.

"How do I open this door? Should I walk back and forth in front of it a few times?" When the door on the wall finally disappeared, Harry walked forward, touched the smooth wall, and muttered to himself, "I'm afraid not. Although this is the eighth floor, it's close to the tower and many people pass by every day. If it was just such a simple trigger condition, it would have been discovered long ago."

"A spell?"

"No, Professor Snape didn't say anything just now."

Even though Snape was right next to him, Harry had no intention of asking him for help.

"Let me think about it..."

“The mind is the magic.”

Harry tried to move, a thought running through his mind.

A door slowly emerged from the wall.

"It is so." Harry said softly, turned his head and looked at Snape, "Professor, please notify Professor Dumbledore to come over."

Snape nodded: "I understand."

He turned around, looked deeply at the door, then turned and left.

Harry waved his wand.

Quinn protected himself with shield, armor, and disembodiment spell, and finally called upon the patronus, a huge one, to completely protect him.

Take all safety measures.

He reached out, turned the doorknob, opened the door with a click, and walked in.

"I need a place to hide my stuff."

As Harry was thinking this, the Room of Requirement agreed to his request and opened a door in the wall.

He didn't think about it.

"Open the room where Barty Crouch Jr. hides his things." Or "The room frequented by Barty Crouch Jr.", after all, he and Dumbledore had erased Crouch's oath with Hogwarts. To Hogwarts, Crouch was a non-existent person.

Moreover, it is difficult to be so refined when performing magic for the general public.

Whether the person who cast this spell was Slytherin, Ravenclaw, or Hufflepuff, it was definitely not Gryffindor.

Harry and his friends had asked Godric for advice, but he knew little more about the castle than the first and second year wizards. He had devoted the rest of his life to educating young wizards or dueling with others.

Traceless stretching spell.

Harry smelled the magic for the first time.

The space in the room was very large, even larger than the school auditorium. The ceiling was so high that it was invisible. There was only pitch black. The moonlight shone in through the bay window. Harry felt as if he had stepped into a miniature carved city.

Over the past thousand years, it seems that many little wizards have broken into this place.

Of course, there are even more house-elves, who seem to particularly prefer this place.

Harry smelled many things that were tainted with the scent of house-elves, discarded furniture, desks, boxes, and cleaning tools. These things were piled up layer by layer to form high hills. They were shaky, but protected by magic. They stood tall and looked dangerous, but would never fall down.

There are also many books.

Most of the books are discarded, and there are even more notebooks with scribblings on them.

Of course, there were also many dead pets, such as owls, toads, and frogs, their dried corpses stuck in the alleys and cracks of buildings.

even……

There are also some strange creature corpses.

The dried corpses of baby dragons, pentapegia, horned beasts, and even a few corpses of goblins wearing armor.

Harry felt a pity.

These have lost the properties of magical materials and turned into ordinary, unremarkable mummies.

Harry continued walking inside.

It is hard to imagine how wonderful Hogwarts was in the past, with steel swords, giant axes, shields, a set of armor worn by humans, and even a few ancient cannons and half of a train cut in half.

Harry suddenly stopped at a fork in the road.

He smelled the scent of dark magic, which was very recent, no more than a month old.

Without hesitation, he continued to cast protective magic on himself and walked towards that direction with big strides.

An ugly statue of an old wizard came into his sight.
