Harry Potter’s Book of Sin

"boom!"

At the back door of Hogwarts Castle, beside the tunnel connecting the inner and outer lakes, two figures were fighting on the water.

On one side is the Mad-Eye Moody standing on the boat, his magic eyes are turning flexibly, always paying attention to the attack from the air; on the other side, it is obvious, just watch the black gas whirling in the air. Know, that is another black death.

The experienced and retired Auror made a very accurate judgment. When the front door was attacked by a large number of Death Eaters, the enemy really had arrangements at the back door.

Voldemort had been to school at Hogwarts, and he must be very clear about the terrain here. It was for this reason that Moody hurried to the back door.

But this route is actually not suitable for offensive purposes, because there are not only humans and fish inhabited under the lake, but there is even a huge squid that is surprisingly large.

Although these aborigines were forced by the agreement with Hogwarts and never attacked the school’s ships, they would not be so polite to outsiders.

Therefore, the route of the underground dock of Hogwarts Castle can only be a sneak attack.

At this moment, Moody was holding a magic wand, continuously releasing spells into the air, but found that it would be difficult to hurt the opponent if he tried his best.

Although he is not in any danger for the time being, it is definitely not enough to consume it this way.

"boom!"

There was another impactful muffled sound, and the black dead who had just rushed towards Moody were knocked off the angle of flight again, and flew out for a long distance while wiping the lake.

"What the hell is this!" Old Moody said furiously, "I don't know when that kid will come back!"

With that, he paused hard on the crutches, forcing the boat that was swayed by the impact to stabilize.

Although Maca also mentioned the existence of the Black Death, he still hasn't figured it out yet, how could he explain it clearly?

For most modern wizards, this thing is really difficult.

As a last resort, Moody had to keep pushing it back, while controlling the boat under his feet to retreat a little bit.

It is really not good for him to meet on the boat.

...

In the auditorium, the three Harry, like the other students, were discussing the situation outside in a low voice.

Of course, it is not so much a discussion as a guess.After all, they are nestling here, and it is unknown what the situation is outside.

"...Don't you want to go out and see?"

Sure enough, this sentence was still spoken, but it was surprising that it was Hermione who said this sentence.

"Hey! It's not like you!" Ron looked at Hermione with a weird look. "From just now, you were a little strange to put it before. You must be the first to disagree with this kind of thing! "

"Really?" Hermione glared at him, "I just don't worry about Hagrid, and... and we haven't seen where Maca is..."

When he heard the word "Maca", Ron scratched his hair vigorously, and closed his mouth with a weird expression.

Hermione was obviously using Hagrid as an excuse, but she was still thinking of Maca in her heart!

Yes!Ron had indeed given up completely and even encouraged Hermione by the way.But once I heard her mention Maca, I was still a little bored.

"Harry, what do you think?"

Seeing Ron not speaking, Hermione looked at Harry again.

But Harry seemed hesitant to tell the truth, he really looked like going out to see the situation, and he was really curious about where Maca and Fleur were.

but……

"Oh, yeah..." Harry hesitated, "but...how shall we get out? The professors are all watching!"

Upon hearing this, Hermione smiled triumphantly.

"Look!" She took it out of her arms, and then took out a black potion bottle. "This is the gift from Maca to me when the three finalists just decided to choose the Warriors..."

birthday present.

She said the word in her heart, and she immediately felt a warmth quietly appearing.

"...This is the'Xianyin Potion'... If we have three points, although the invisibility time will be shorter, it must be enough for us to leave here!"

She looked around, then quietly pointed to the passage in the side corridor and said: "We are walking from the hallway. There should be only Professor Sprout guarding there! Now the door must be closed. If we want to go out, You have to go through the back door!"

"Be careful, don't make any noise."

After that, she gently pulled off the cork of the potion bottle, poured some into her mouth, and handed it to Harry.

If other invisibility potions were used in the public, people would definitely find out, but the properties of the immortal potions made Hermione disappear unconsciously.

As Hermione's presence gradually diminished, Harry and Ron only blinked a few times before she could no longer be found.

They subconsciously looked around, it was really hard to imagine the principle of this kind of invisibility.

When Ron also drank the potion and disappeared before Harry’s eyes, Harry took a deep breath, picked up the potion bottle Ron had placed on the ground, and drank the remaining potion with a tangled face. .

But to be honest, it is actually a very bad thing for three little wizards who can't see each other to follow the same route.

The advantages of Xianyin Potion are indeed very obvious, but the shortcomings are also obvious. This type of medicine cannot speak or make a noticeable sound, and it must be noted that it must not be touched by anyone.

But right now, there are really only two ways to get out of here.

One is naturally the gate of the auditorium. Although it leads directly to the lawn outside the castle, the entrance is now full of professors; the other is to go through the corridor to the entrance hall, and then go out through the castle gate.

Generally speaking, the gate must be an important defense route.But because there is the Hogwarts Castle's self-defense magic stone pier knights there, only the herbal medicine professor Pomonas Prout stayed there.

Yes, of course there was nothing wrong with Hermione choosing that path.But the point is that the three of them can't see each other at all now!

If they accidentally touch each other, the invisibility effect will immediately be invalid.

Hermione had read the instructions for the use of the potion that Maca wrote to her, but she didn't remember the problem until she drank the potion.

"……How to do?"

Hermione stood there, watching Harry and Ron drank the potions one by one, but unable to speak, she took an anxious look.

"I'm sorry, Harry, Ron!" As she walked quickly toward the corridor, she prayed innocently in her heart, "...that... good luck to you!"

When Hermione came to the hall lightly all the way, she immediately found that the heavy door had indeed been tightly closed.

Professor Sprout was not at the gate, Hermione glanced at the spiral staircase on both sides of the gate, and the professor was probably guarding in the upper room!

She glanced cautiously into the corridor on the right, and then crept around the stairs to the long passage leading to the underground dock at the back door.

...

Not to mention Hermione's side, Harry and Ron had just passed the side corridor one after another.

No way, after they realized that they couldn't see each other, somehow, they immediately felt a little guilty.

The three of them still have a caregiver. At least if there are people around, you can at least feel relieved.But now they all felt as if they were the only one secretly leaving the auditorium.

The two stood there with their heads shrunk for a while, constantly watching back and forth, until they remembered that there was a time limit, they had to move their legs apart and "moved" from the middle of the classmates to the passageway in the side corridor in a panic.

If someone could see through the invisibility, they would see such a scene. Two little wizards in Gryffindor wizard robes, with their heads shrunk and on their toes, walked towards the hall like two thieves. .

They even walked the same route, with Ron in front and Harry behind, wincing to the other corner of the side corridor.

Then Ron suddenly stopped

"Oh ah!"

With two low voices overlapping each other, Harry's entire face was placed on Ron's back. Needless to say, both of them were taken aback!

Ron turned around abruptly, and the two of them covered their mouths and widened their eyes. They looked at each other with horror, and looked at each other at a loss.

Harry hurriedly pointed his finger at the corner, and Ron nodded immediately and glanced at the hall outside.

When Ron finally saw that there was no one in the hall, he turned around, waved his hand vigorously at Harry, and then pointed to the passage behind the stairs.

When Harry nodded, the two looked into the hall again, and after confirming that there was no one, they ran lightly towards the dark passage.

Their figures had just been submerged by the darkness in the passage, and a person immediately walked down the spiral staircase by the gate.

That was the fat Professor Sprout. She looked at the entrance hall warily for a while, and even checked it with a spell. After finding that there was no one, she went back to the observation room with a look of confusion. .

The battle at the school gate is still going on, and she must stay here in order to be ready to notify Professor McGonagall to come over and open the Stonepier Knights.

...

In the dim passage, there is a torch for a long distance to provide light that can barely see the ground ahead.

This passage is slightly inclined downwards, leading directly to the underground dock at the back door. Every new student will walk through here and go to the auditorium to attend the welcome dinner.

At this moment, Hermione was walking as lightly as possible to avoid echoing when she walked around.

But just when she could almost see the outline of the back door, she found that there was a sound of footsteps that made her chill out from behind.

"Those two fools!" She leaned sideways against the wall in a hurry, clinging to the corridor wall without daring to move.

"Who?"

A rickety figure suddenly walked in outside the back door, carrying a lantern and looking inside it was Filch the janitor!
