Fortunately, Irina's sliding motion allowed her to slip under the troll and end up behind it just before the club fell.
"Bombarda!"
While running out of the bathroom, she did not forget to turn back and attack the troll's backside with a Blasting Curse.
"Arrgghh!"
This Blasting Curse seemed to have really caused trauma to the troll. The troll let out a painful howl, and then its eyes turned red, and it chased after Irina with its club.
At this time, Irina had already run out of the bathroom and met up with Harry, Ron and Hermione.
Hermione had come to her senses after the huge shock. When she saw Irina running over, she met up with Irina and cast a Conjunctivitis Curse at the troll.
"Harry, Ron, you go find a professor first, Hermione and I will hold it off!"
Irina ordered, she backed away and used Freezing Charms to slow down the troll's movements.
Although her Freezing Charms were ineffective at freezing it, the frost that continued to form on the surface of the troll's skin was constantly slowing it down.
"No, we will defeat the troll with you!" Harry said loudly.
Ron also nodded in solidarity and said, "I was wrong before, I will never abandon you!"
Irina was about to vomit blood.
"Don't you know your magic level? With the troll's magic resistance, can you break its defenses? Hurry up and find a professor!"
Irina was about to collapse.
Hearing this, Harry and Ron looked at each other and nodded.
"Okay, you better be careful!"
Then they turned and ran out.
Finally, no one was holding them back, and Hermione worked in tandem with Irina's attacks.
Although Hermione's Freezing Charms were not as powerful as Irina's, their goal was not to freeze the troll or kill it, but to slow it down until a professor arrived.
However, things did not go as they wished.
The troll seemed to become even angrier under the attack of the two. In its eyes, being toyed with by two little girls was a huge shame!
This troll was like a video game boss that entered a berserk state. The frost condensed on its body surface shattered from its brute strength, and the thick wooden club was swung out by it with tremendous force, sweeping across the floor.
Irina rolled over and narrowly avoided the club's sweep, but Hermione was unfortunately struck in the back. Her body flew backwards and smashed into the wall dozens of meters away, knocking her unconscious.
Seeing this, Irina was a little desperate.
Harry and Ron had just left, and they would definitely not be able to bring a professor back in a short time. And her spells were almost useless against the troll, which left her in a dire situation.
"Crystal clear like a spring! Frozen ground, icy sky!"
Irina gritted her teeth and almost overexerted the little magic power left in her body. A large amount of water flew out from the tip of her wand and turned into solid ice shards under the control of her Freezing Charm.
These solid ice shards exploded under Irina's control and turned into countless sharp icicles.
"Go!"
Irina waved her wand vigorously, and these countless icicles shot towards the direction of the troll like a hail of bullets.
However, even though the icicles were powerful, they were no match for the troll's thick hide.
These icicles could only scratch the troll's skin, causing it to bleed a little, but they could not cause any further damage.
The troll strode forward, swinging its club and continuously striking at Irina.
At this moment, Irina's magic power was almost exhausted, and as a girl, she had already tired out. She could no longer dodge these terrifying attacks.
Thump...
Her legs gave out, and she stumbled and fell forward, completely losing hope of dodging the attack.
Damn it, if I had known earlier, I would have dragged Hermione back to the Great Hall!
Irina regretted it very much. Why was she so softhearted?! As a result, she was going to be finished too!
At this moment, a golden beam of light pierced through the air and struck the troll's coconut-like head fiercely.
The huge force hit the giant monster, causing its movements to veer off greatly, and the thick wooden club also flew out of its hand.
The wooden club struck Irina's side hard, and the shockwave threw the petite Irina away.
Irina looked in the direction where the light beam came from.
She saw a black-haired boy slowly walking out from the shadow of the corner, and dozens of metal cubes were suspended around the boy. These metal cubes were emitting strong light, and seemed to be accumulating power.
The black-haired boy had dark red eyes, and there seemed to be a dark red glow flickering at the ends of his hair. His eyes were staring intently at her.
"Stand back, leave this to me."
Lynn said lightly, and walked towards Irina.
The dozens of metal cubes floating around him seemed to have completed the accumulation of power. Dozens of golden beams like before burst out from the metal cubes and continued to bombard the giant monster.
Bloody holes appeared on the troll's body. These golden beams seemed unusual. There was a golden energy corroding the troll's flesh from the bloody holes, expanding the troll's injuries.
"Senior, you..."
Irina looked at Lynn in disbelief.
This black-haired boy should only be in his second year, how could he have such immense power?!
In her opinion, even the professors of Hogwarts might not be much better than this!
Lynn glanced at her, took out a bottle of potion from his pocket and tossed it to Irina.
"Healing potion, enough for two people."
As Lynn said, a flame ignited in his left hand.
This flame glowed with black light. This was the forbidden Hellfire that Lynn had previously refined at Nicolas Flamel's manor.
Although the giant monster relied on brute force, the Hellfire's forbidden magic power had no effect on it, but the flames that integrated alchemy itself had a higher temperature, and its lethality was naturally far greater than ordinary magical fire.
Lynn swung his left hand, and the Hellfire flew out immediately, clinging to the surface of the giant monster's body like barbed thorns, constantly burning its flesh.
As the flames flew out, Lynn waved his wand with his right hand, and the rubble on the ground suddenly turned into countless vines, entangling the giant monster's feet, immobilizing it.
Under the burning of these terrifying flames, the giant monster kept screaming, but without its club, it had no way to retaliate with such a bulky body. The flames kept burning the giant monster's body, charring its skin black.
On the other side, the metal cubes around Lynn were also constantly shooting golden beams, causing greater damage to the giant monster. A few minutes later, a thicker golden beam burst out from the giant's left eye socket, blasting its head, and the giant's bulky body finally collapsed.
Irina came over to take a look. The giant's head was completely obliterated, and countless blood mixed with brain matter exploded all over the floor. This disgusting scene made Irina vomit nonstop.
