The Halo 2000 flew around the castle and attracted the attention of countless young wizards for a while.

It's human nature to watch the excitement, even wizards are no exception. Everyone followed the broomsticks from a distance, and ran quickly towards the castle gates.

Professor Quirrell stood alone in the hallway, and when he spotted no one around, he quickly removed his bulky shell.

Quirrell also wanted to take this opportunity to go to the forbidden area on the fourth floor to have a look, it was not convenient to move in this body.

Just then, a pop rang in his ears, and Quirrell turned his head to catch a glimpse of a broomstick flying straight around the corner.

The broomstick fully demonstrated the superior performance of the Halo 2000, which drifted 90 degrees in the air without even reducing its speed.

Because of the corner, Quirrell failed to spot the broom in time, and the two sides were already less than five meters away.

Quirrell hadn't studied physics, so he couldn't brainstorm how many tenths of a second it would take for the broom to hit him, let alone calculate how much kinetic energy he would get if the two sides collided.

But it doesn't stop him from being acute...... Can't hide!

Professor Quirrell's eyes flashed with a gleam, and in that moment, everything seemed to stand still, and Quirrell was already in his memory palace.

He took the form of Sherlock Holmes, folded his hands in front of his mouth, and contemplated the consequences.

There are no more than two options......

Attach a broom to your face, or use the back of your head.

Once hit in the face, it can be disfigured in the light and concussed in the worst...... There may even be amnesia.

So, how else did he complete the task of resurrecting the Dark Lord?

If you choose the latter, the special magic of one body and two faces, can transfer the damage away, reduce your own damage, and better retain the useful body.

but

That's the face of the Dark Lord!

Forget it, it's still the task, and if you can't bear it, you will make a big plan.

Quirrell didn't hesitate to twist his head back.

The mahogany touched the scarf and slammed it against the back of his head, and Quirrell felt a strong force as he flew forward, sliding down the hallway for more than ten meters.

At that moment, Quirrell's body let out a heartfelt wail, and the sound reached deep into his soul.

But this was just the beginning, and the wizards in the distance rushed over, all the while looking up at the broomstick, not noticing that there was still a person lying on the ground.

Professor Snape, who was the leader, took the lead and stepped on the back of Quirrell's head.

The professor snorted, nice touch, as if he had just stepped on something.

He was about to turn around and check, but the crowd behind him was already running towards him.

Forget it, whatever, let's go see what's going on outside.

At this time, there was less and less ice in the middle of the Black Lake, and there were more and more mermaids surrounding William and them.

William shouted, "Come on the broom!" ”

The sound of breaking the air suddenly sounded, and the light wheel 2000 flew quickly. It flew into the Black Lagoon and came to a halt in mid-air beside William.

William flipped over his broom, Cedric followed, Fred grabbed the end of the broomstick, George grabbed Fred's legs, and the four of them soared into the air.

An angry clamor erupted in the merfolk swarm.

The old merfolk patriarch waved the huge trident in his hand.

William had thought it was just an ornament, but now it didn't seem to be the case, and as the old man chanted a spell from his mouth, the ice in the Black Lake melted, and a large amount of water vapor filled the air.

He waved again, and the lake swelled in an instant.

William didn't care about Fred and George, who were floating in the air, and only shouted "Be careful", and his speed soared, and he shot far away.

Walked, walked, hehe~

With the swing of the trident, the surface of the lake was cleaved with a bang, and a wave rose up to five or six meters.

William flew towards the castle, the old manfish's trident moving in his direction.

William braked suddenly, stopped the dive in time, and leaped up. A jet of water rushed over, and if he didn't avoid it in time, he would have been sprayed right in......

William controlled the broomstick and kept circling the Black Lake, dodging one jet after another of water.

Soon, the little wizards also came, and everyone saw the battle.

Snape gloated, "Hehe, who told you to mess with the merfolk?" ”

As everyone continued to exclaim, William turned left and right, and had already crossed the Black Lake and flew above the crowd.

The twins constantly greet the wizards on the ground; Cedric spotted a gloomy Snape, who quickly hid the mermaid hair in his hand.

He didn't want to be snatched away by Snape after all his hard work.

The mermaid patriarch saw William and the others fleeing, and his daughter had no "husband", and plunged a trident into the water with a trident, and a wave of blue pools was provoked by him and fell towards the shore.

Originally, the black lake was still noisy, but in an instant, the lake roared and splashed, like a torrential rain, and everyone's clothes were soaked.

Snape angrily stroked his wet hair, and a puddle gathered under his feet, all of which were black and purple in color, and even had a large amount of greasy matter floating.

The quartet, as the perpetrators, has returned to the castle.

"I didn't expect the mermaids in the Black Lake to be so powerful?" Cedric sighed.

No wonder Ollivanders never used mermaid hair, it was too dangerous.

"Merfolk shouldn't have this kind of combat power, and their classification level in the Ministry of Magic is also xxxx, similar to trolls." William analyzed.

"It should be the trident in the hands of that old manfish, and it seems to be able to control the Black Lake."

"Wow...... It can't be any of the Big Four, the treasure left behind, right? Fred excitedly, "It's like Gryffindor's sword, Ravenclaw's bronze ring......"

"Can we go down?" George asked.

They had just provoked the mermaids, and now they were thinking about diving to the bottom of the Black Lake, and if they didn't die, they wouldn't die.

"There are many ways to dive into the Black Lake." William laughed, "Closing potions, soaking spells, and even using Animagus to turn into fish."

Of course, the easiest way to do this is to use gill sac grass! ”

"What is a branchial sac grass?"

"A precious aquatic magical plant that grows in the Mediterranean, it resembles countless slippery gray rat tails.

Eating it can make people grow gill flippers and move freely underwater for more than 1 hour.

Of course, there is also a kind of tentacle of King squid, if you use this tentacle instead of gill sac grass, to make a diving potion, it can increase the effect to a week. ”

"Where?" Cedric asked.

"It's in Professor Snape's medicine pantry." William sighed.

These were all good things he had seen in the time loop, but they were all hidden away by Professor Snape.

But even with these, William and the others can't take away the trident.

Merfolk can't get ashore, but William isn't their opponent when they're in the water.

So they can only think about it.
