The door is closed.

Ranko took his wand and scrutinized Professor Haronius' neck. He was led into the room and immediately used a spell to cut through the thin thread, which allowed Professor Harlenius to escape his control and die without being suspended in mid-air.

Professor Harlenius coughed violently, feeling like his throat was burning through a large glass of spirits.

"This thing, ahem, there's something wrong with this room......"

He was unknowingly tricked!

At this moment, Professor Harlenius's chest flickered slightly, and he was half-lying on the ground, leaning against the door that could no longer be opened, gasping for breath and roughly pulling out a shrunken crystal ball from his chest with a faint light.

"Hit......" His face was still ugly, but that dead man-like appearance was gone.

The miniature crystal ball was imprinted with the strange situation he had before, and the black-and-red patches and the threads on his neck that resembled the hanged man all indicate who this method came from.

In the dark room, even though the tip of Professor Malfoy's wand was faintly glowing, it still couldn't fully illuminate the surroundings.

The feet are dusty, and it is unbelievable that in a place where there are house-elves, there will be a pile of dust of such a thickness.

"It's a curse of substitution."

Ranko examined the imprint on Professor Harlenius' neck and found no source of the curse, which must have slipped away when he 'cut off' the curse connection.

"Death in lieu of death? The stuff in the room wants me dead so he can get out?! ”

Professor Harlenius tucked the miniature crystal ball back into his collar, feeling the coolness of his neck, Professor Malfoy's wand against his neck, the bluish-black wound that had been pulled by the thin thread, which was rapidly healing with the healing spell.

"Sorry, and thank you." Professor Harlenius whispered.

This time, after all, it was he who caused Malfoy.

"You're welcome, it's your responsibility." Ranko raised an eyebrow.

I used to get along with this professor who looked like a depressed uncle, and Professor Malfoy's familiarity with the other party was amazing, but now I am a little uncomfortable with such politeness.

I didn't waste too much time reviewing my own problems, and several other professors should still be out trying to get in.

Ranko re-ignited the tip of his staff with the Fluorescent Flicker Charm, motioning for Professor Haronnius to look back.

"The door can't be opened, it's not your average lock."

Behind them was the door that had been ajar before, but it was now completely closed, and a mottled moss-like black-red substance filled the entire door, obscuring the original walls inside.

He had tried the Lockpicking Charm before, but it only unlocked Muggle locks and was of little use for magic locks.

Professor Haronnius got up from the ground, ignoring the dust stuck to his body, and directly used the Patronus Charm.

He is Durmstrang after all, even if he is not good at facing this kind of situation involving 'dark magic', 'curse' and 'resentful spirit', he can still make the most correct judgment.

The silver highlights are more brilliant than the fluorescent flickering, and Professor Haronnius' patronus is a squirrel with a tail in the shape of a hat, standing on his left shoulder, looking unusually well-behaved.

Patronus Charms are defensive spells that use the happiest things in their hearts as a source of power, and while most wizards are unable to cast a full Patronus, even shapeless Patronuses have surprising defensive abilities (especially against dark magic creatures or spells that damage mental damage such as Dementors).

"There are ...... all around"

Professor Harlenius had summoned a complete Patronus, and the squirrel with its beautiful silver body was staring unblinkingly into the darkness not far away, as if something terrible was inhabiting it.

Professor Harlenius was holding his wand, and he was terrified.

Even if he is a wizard who is not good at fighting, if he is familiar with the situation of the school, even if he does not have a wand, he will always have a lot of means to deal with the damage of the dark arts, but in the case just now, except for the miniature crystal ball inherited by his family, none of the other means of dealing with it have taken effect!

"At least it's a 4X-level wraith."

No one expected that the resentful spirits in the castle had grown to this extent.

"Hey, Malfoy...... Malfoy? ”

Professor Harlenius didn't hear Malfoy's voice as he was observing the door, and he turned his head in astonishment, but at this moment the squirrel on his shoulder suddenly exploded, and the silver points of light escaped like catharsis in all directions, repelling the thick darkness that eroded around him.

Before it was too late to observe what was going on with Malfoy, Professor Haronnius raised his wand and cast a spell on the darkness in front of him, trying to break what was hidden in the darkness.

——

Meanwhile.

"The door won't open."

Professor Van Sent shook his head at Professor Danlin with a solemn expression, and Professor Danlin stepped forward silently to carefully inspect the door.

"Something locked the door inside."

Professor Van Sente whispered, "I'm afraid it's a vengeful spirit that is not weak. ”

How could Durmstrang have a grudge, Professor Van Sent didn't want to know. But judging from Professor Harlenius's abnormal reaction and what he said just now, it is likely that the resentful spirits that were originally locked up here are about to break through the restrictions set by the original school.

"...... over at the castle"

"Professor Merino."

Professor Danlin interrupted Professor Van Sent as she looked to the side, leaning against the railing of Los Merino, who had been silent since the beginning.

Professor Merino raised an eyebrow, didn't say anything more, took his wand, and stood in front of the door.

Professor Vincent swallowed back what he had just said, and together with the other two professors, he took a step back.

Professor Merino's wand was aimed at the door, and in the next moment a loud explosion exploded in front of the door, accompanied by the roaring thunder and lightning that had accumulated over the castle......

But it didn't work.

The bombardment of the usual spell had no effect, the door seemed to be indestructible, Professor Merino's face remained unchanged, his lips moved slightly, and no sound was heard, and the second spell struck the door shortly after.

The ground had been corroded into grooves of different depths, and the surrounding stone walls had been corroded to varying degrees, but the door remained unchanged.

Then came the third and fourth...... The black magic became more and more powerful in Professor Merino's hands, and even the ground began to shake with it, and the medieval armor that was originally standing on the four floors obviously noticed this, they didn't know when they turned their helmets, and their eyes were black holes, which looked a little terrifying.

The rest of the professors didn't come forward to help, and Professor Danlin watched carefully at the changes that took place on the door, and after a while, she seemed to have noticed something, and shouted as Professor Merino's next spell was issued:

"Stop!"

But Professor Merino couldn't take it back.

Just as she spoke, the spell in Professor Merino's hand had been thrown out, and the door that had been bombarded by various spells in turn without the slightest crack opened at some point.

As soon as Professor Harlenius emerged, he saw his head the size of his head, and the fire that burned all his senses was slamming into his head!

Professor Harlenius: ???

Professor Harlenius: !!
