There was a corridor behind the door, and several people walked along the corridor.

After walking a few steps, Fred suddenly asked, "You say, what treasure is Headmaster Dumbledore hiding here?"

"You want to hit that precious idea?" Albert paused, turning his head to look at Fred, who had almost bumped into him, his brow slightly raised.

"Isn't it curious what kind of treasure needs so many professors to set up mechanisms to protect?" Fred didn't care about Albert's tone, and said to himself, "That devil's net should be Professor Sprout's mechanism, and it must be Professor Flitvier's handiwork who spelled those keys, as well as Professor McGonagall's giant chessboard array, and the three deans are involved, so ......"

He didn't say what he said later, but everyone understood what he meant.

What was it that Headmaster Dumbledore had so much trouble protecting, and if not something very valuable, did it really need to be done to this extent?

This incident really piqued everyone's curiosity.

"I'm also curious. ”

"Just think about it, don't expect to get your hands on it. Albert reminded, "I expect Headmaster Dumbledore to know we're here soon." ”

The three of them were stunned when they heard this.

"It's strange, it's Headmaster Dumbledore, after all, how could he not be able to monitor the situation here. Albert pursed his lips and laughed at himself, "Do you think these mechanisms are difficult enough to stop the thief who wants to steal the treasure?" No, I prefer to believe that the Headmaster is going to use this to catch the thief." ”

All three were silent, for Albert's words were reasonable.

Is it difficult for the professors to set up the mechanism?

It doesn't seem to be very difficult!

It's really not difficult, although if they're not careful, they can just get deflated.

Wait, thief, do you mean us?

They were all curious about who these institutions were for?

Albert might know something, but he certainly wouldn't tell them directly, so he didn't ask for it.

"The three Deans are involved, and Snape is probably no exception, and it is very likely that we will face the mechanism that Snape has set up next. George changed the subject and said his guess, which was actually quite plausible.

As they spoke, several people came to a door.

As soon as they looked at each other, Fred stepped forward and opened the door.

The moment the door was opened, a disgusting stench hit their nostrils, and they almost subconsciously lifted their clothes to cover their noses.

The next moment, there was the sound of chains tugging inside the door, and a deafening roar came from inside the room.

Albert almost instinctively reached out and pulled the door back shut.

Oh, my God!

It smelled horrible!

He felt like he was about to burst into tears.

"It's a troll!"

Fred took a few steps back, not because he was afraid of the trolls, but as far away from the door and the terrible stench as he could, wanting some fresh air.

"Are you sure this is a trap set up by Snape?"

"It should be Professor Quirrell's mechanism, and the trolls are mentioned in the Dark Forces Self-Defense Guide. Albert and the others walked away from the door, and only when the terrible stench could no longer be smelled around them did they begin to put a bubble head charm on everyone.

"It's so much better. Lee Jordan couldn't help but complain, "I don't suspect that the troll was actually trying to smoke the people who entered the room to death." ”

Albert didn't care about Li Jordan's complaints, and reminded: "Don't kill the trolls inside directly, I'll throw a glowing spell into it later, you use a stun spell on it, try to stun it as much as possible." Normally, we shouldn't have to fight the troll directly, there would have been some easy way to subdue it. ”

A few people nodded, indicating that they understood!

In the face of the trolls, they didn't have the same anxiety as before, obviously the trolls were even more dangerous than those chess pieces, but they had the experience of slaughtering the two-headed trolls, and the four of them didn't feel much fear and uneasiness when facing the trolls.

"Three, two, one!"

When Fred reopened the door, Albert immediately threw a ball of light inside, and the dimly lit room was completely illuminated.

The four raised their wands and fired a stun spell at the trolls inside.

The troll, hit by the four stun spells, shook its body as if drunk, and instead of falling, the troll stood firm again, shaking its head and looking at the four young wizards who had broken into the room.

"None of them were knocked down!"

Fred, George, and Lee Jordan all had shocked expressions on their faces, knowing that this was a coma spell used by four people together, and ordinary people were set on fire like this, and it was estimated that they could only be sent to St. Mungo's Magical Injury Hospital.

"Obstacle Charm!" Albert shouted.

The troll in front of him was far bigger than the last two I had encountered.

"There are many obstacles!"

The crowd shouted in unison, and a spell shot from the tip of the wand, striking the troll's body, causing the troll to froze as if some great force had restrained it.

"What to do?" shouted Fred, "how many more stun spells?"

The effect of the obstacle spell will not be long, and the trolls may break free at any moment and move, and they must do something to subdue it once and for all.

"Destroy its weapons first. George prepares to use the Explosive Charm to destroy the troll's stick, but Albert stops him.

"Let me do it. ”

Albert simply waved his wand, and the wooden stick in the troll's hand flew into the air.

When the troll regained its mobility, it was stunned to find that the weapon in its hand was gone, it looked at its palm, scratched its head in confusion, and the wooden stick commanded by Albert cut a graceful arc through the void, and struck the back of its original owner's head.

An earth-shattering sound echoed through the room, and the troll swayed in place as if in an exaggerated dance, stumbling a few times, and falling face down to the floor.

The sound of "boom" shook the whole room.

"That's it...... Win?"

Li Jordan's eyes widened in disbelief, he originally thought that he would be entangled with this troll for a while, but he didn't expect to solve it so easily?

"I've studied trolls, and the only thing disgusting about these guys is the smell of them. Albert cautiously stepped over the troll's stout body and headed for the opposite door.

"Is the weakness the back of the head?" asked Fred, who reached out and patted his head.

"That's right, one of the weaknesses is the back of the head, and attacking there can make the troll faint. ”

"Let's go, I don't want to stay here any longer. George muttered, and he reached open the wooden door and walked in first.

"Next, it's supposed to be Snape's mechanism!"
