Harry!! …… Well, you've passed out, Ron! Cast a curse on it! I need to get out of the wall! It's so close to me! ”

Ron was still stupidly clubbing, he looked too scared. Brandi tried to call him, but the troll's attack had arrived, and Brandi had to twist suddenly, dodging the water pipe smashed by the troll, and a large amount of rubble splashed on Brando's body, and he only felt a burning pain in his back.

But he didn't have time to worry about that, and while the troll was pulling the tube back, Brandi quickly jumped onto the half-demolished ruins on the right. It had been a sink, but the delicate platform had apparently been broken into a twisted mass by the trolls, and from time to time a column of water gushed upwards. He turned his head, his wand pointing like a sword at the troll that had turned.

"Incendio!"

A ball of fire, the size of a human head, suddenly appeared, flying towards the troll's head.

The troll's head is actually very small, and it is far away from Brandy, so ordinary evil spells don't hit it very well, but the fire charm is different, it is an extremely pure magical flame itself. After breaking away from Brandy's control, it quickly rose into a large fireball with a diameter of nearly three feet in the storm, directly enveloping the space above the troll's shoulders simply and rudely!

"Whew!!" The troll in the firelight let out a scream, and the firelight temporarily took over its vision, but it also provoked ferocity. The troll ignored the astonishing heat on its face, its eyes closed, roaring in rage, its long ape-like arms grabbing the brass hose in its hand, waving it in the air a few times, and suddenly swept ferociously towards the place where it remembered Brandi standing.

The hose whizzed through a semicircle, and in an instant, Brandy's hair stood on end, and he quickly threw himself backwards, rolling down the sink and tumbling to the back of the pool.

However, he still underestimated the power of the troll, and before he could even adjust his posture, Brandi felt a sharp shock in his back, followed by a loud crash, and the thick marble platform behind him was torn apart by the impact, and Brandi was thrown away with the remaining strength.

"Ahhhh Blondie! ”

Ron yelled hoarsely, his face flushed with anger and shock. At this moment, he hated himself incomparably, why could he be so frightened that he couldn't move... Why can I be so weak...

Anger and pain suddenly overpowered fear. He waved his wand quickly, and the silver-white light quickly sank into the body of the troll that was trying to kill it all.

The troll's body shuddered rapidly, and it seemed to want to make some strange gesture for a moment, but then, its thick, filthy anti-demonic skin helped it break free from the grip of Tarantella's spell. It stared blankly at its outstretched hand in a strange direction, and then realized that it had fallen for the tricks of the humans.

It turned around in annoyance and threw the bent hose in its hand at Ron. Ron lunged to the other side, but the hose was too long, and he seemed to be too late!

"Yuga Dim Leviosa!"

Just as the hose was about to hit the target, the force of the forward rush suddenly disappeared, and the twisted pipe seemed to be free from the constraints of gravity, suspended up and down in front of Ron's eyes for a while, and then fell straight down.

"Whew! Call! Ron was sweating profusely, panting, and at that moment, he had almost closed his eyes in despair. He looked around gratefully, trying to find his savior.

But when he found her, Ron had mixed feelings.

Not far away, Hermione and Parvati finally conquered their fear at a critical moment, Hermione was trembling and pulling out her wand, standing up against the wall little by little, she was still scared, but at least she was trying, her levitation charm saved Ron's life!

"How's Brandy?" Hermione didn't pay attention to Ron's expression, her eyes fixed on the troll that seemed to be bewitched by magic, and asked in a trembling voice.

Parvati skirted the troll from the side, slipped behind it like an agile cat, and lifted up Brandi, who was groaning in pain on the ground, and he was miserable, baptized with rubble, and barely had a good piece of meat, but fortunately, at least he could still speak.

"Don't worry, ahem! A little bruising" In order to reassure Hermione, Brandi deliberately waved his arm at Hermione, and the stretched muscles led to the wound on his back, and he grinned in pain.

"Don't chant low-level spells on trolls, I've read in books that this thing's resistance is too high." Hermione breathed a sigh of relief as she leaned against the wall and slowly moved, trying to get closer in Brandy's direction without attracting the troll's attention. "We're going to have a lot of damage to our spells!"

"It doesn't have any weaknesses?"

"Yes, hit it on the head! That thing is so small, it looks fragile! Of course, if you can get it......"

Brandi rubbed his head and thought desperately, and suddenly he saw the water pipe that had fallen to the ground. He thought about it for a moment and came up with an idea. He patted Parvati's hand and motioned for her to let go of herself. "Parvati, please use the levitation charm to make a sharp thing float in a moment, if you are high, ......" Brandi gestured to his chest, "just float in front of me......"

"What are you going to do?"

"Don't worry about that, you'll find out later."

After receiving a skeptical response from Parvati, he turned his head back and said to Hermione and Ron.

"Hermione! As soon as I shout, you'll cast a petrification spell on the trolls! I know you will! The last time I was doing my homework in the library, I saw you learning that! Ron! Ready to mend the knife in a moment! ”

…………

"Huh?" *2

The two of them shouted in unison. Ron pointed to his nose in shock, his mind was blank now, and his magic level was not high, which one did Brandi think of to make himself do the final blow? How could he have any spells to inflict damage on such a thing?

Hermione, on the other hand, pulled her throat nervously and anxiously, "I said that thing didn't work against trolls!" Hold it up and let it stop for a few seconds! Oh! Oh my God, it's starting to go your way! ”

"A few seconds is enough! Believe me! We only have one chance! If it fails... I mean if—" Brandi took a deep breath and looked at the troll slowly leaning towards him. "You take Harry and get out first, and then go find the professor to save me!" I'll buy you time......"

"You're crazy!" Parvati grabbed Brandi's sleeve, "You can't even move now!" How to buy us time? ”

"I've learned an advanced magic from the Sorting Hat, and it probably protects me......," Brandy's eyes flickered, and he slowly broke free of Parvati's hand, his backhand a red light that left a mark on the troll's leg. The troll was in pain, and walked a little slower. "Hurry up and prepare, we're running out of time......"

"No, you can't! Absolutely not! Hermione looked at Brandi pleadingly, her eyes filled with tears. I can't leave you like this, you're going to die......"

"No one will die!"

A rough roar echoed through the room, and Hermione's whole body shuddered, and her face was as white as paper. She had never heard Brandy roar so loudly. "Do what I say! Hermione! Trust me! ”

At this point, no one had the time to fight anymore, Parvati choked and chanted a spell, pursed her lips, and levitated a crumbled floor tile with sharp edges from the ground, slowly floating in front of Brando.

At this time, the troll was less than five meters away from Brandy, and he could even see the terrifying appearance of the troll after being burned by the fire.

"Hermione !!" Brandi suddenly shouted hoarsely, and his wand began to wave rapidly, streaking through the air in mysterious tracks, and the magic poured out like a flood that opened the floodgates, almost half of which evaporated in the blink of an eye. But he didn't dare to slow down the speed of his mana output in the slightest, and instead he gently spat out a prefix after his wand swiped a semicircle.

"Spell casting—"

On Brandi's wand, layers of mysterious magic patterns suddenly emerged from the tail of the wand, and silver runes slowly moved forward around the wand, extending towards the tip of the wand. Invisible pressures began to permeate the small space, which was clearly a high-level magic. Even the troll vaguely felt that something was wrong, and it began to desperately try to get closer to Brandy, picking up a stone slab on the ground.

Hermione, on the other side, heard Brandy's roar and quickly wiped away the tears from her face, she struggled to control her shaking hands, chanting incantations in a crying voice.

"It's all petrified!"

The troll's body suddenly stopped moving, the joints of its body suddenly stiffened together, like a bearing rusted to death due to lack of lubrication, it roared angrily, struggling desperately with all its might, and the glow of magic on its body was constantly dimming...... The magic of the petrification spell obviously couldn't control it for too long.

But that's enough! The runes on Brandi's wand had condensed to the tip of the wand, and it was moving rapidly around it, and the purple lines were completely covering the wand, and the tip of the wand was now condensed with a rich purple color, like substance.

His breathing at the moment is as difficult as a bellows, his whole body feels hot, every blood vessel seems to be roasted on the fire, surging heat waves continue to erupt from his chest and abdomen, and his vision begins to flicker, maintaining a supermodel state for a long time has already drained all the strength in his body, and now he is completely relying on an obsession to support himself from fainting immediately.

He propped up his wand and aimed it at the struggling troll, who had managed to free his left hand that was gripping the slate, and it danced so hard that it flew out of its hand towards Brandi.

At the same time, Brandi finally finished the spell and opened his mouth with difficulty.

“Scattertheweak！ (The weak retreat)"

The next moment, the world turned purple.
