"Knock knock."

Heavy footsteps drew closer, followed by a large black shadow in the toilet doorway, accompanied by a heavy wheezing and the cooing of wild beasts.

Hermione suddenly had a bad feeling in her heart, her face turned pale with fright, and she shrunk into a ball and hid behind Wanwan's back.

"What kind of monster is this!"

At the same time, the stench of old socks that had not been washed in years and public toilets that had never been cleaned was disgusting.

The next moment, the monster revealed Lushan's true face, making Hermione's heart almost stop.

It was a giant monster that was a foot tall, its skin was dark gray, like weathered granite, its body was bloated, like a large pebble, with two short legs as thick as a stump, and a bare head the size of a coconut shell placed on it, it looked a bit like Shrek at first glance, but its body was larger than Shrek's, its head was smaller than Shrek's, and it didn't have its two trumpet-like ears.

The monster also held a wooden stick nearly two meters long in his hand, and due to the length of his body, the stick would keep dragging on the ground when he walked, making a piercing grinding sound.

It seemed to be very interested in the toilet, and after looking at the toilet for a while, it actually walked in.

"It's a full-grown cave giant, I've seen it in books." Hermione stammered.

"That's great, it's up to you to fix it." Wan Wan said.

"What!"

Hermione thought she had misheard, and when she saw Wanwan nodding, she realized that Wanwan really thought so, and said with a pale face: "The skin of the cave giant has a strong immunity to magic, and the professor has not taught us to attack magic spells, I can't beat it at all, let's find a way to escape." ”

"Don't give up so easily." Wan Wan said.

At this moment, the door of the toilet suddenly "clicked" shut, and at the same time, there was a sound of locking outside---- someone closed the door outside, and locked it, presumably to lock the troll into the toilet.

Unfortunately, they didn't notice that there were two people in the toilet, and the troll's body was so large that it blocked all the toilet doors.

"You see, this is providence." Wan Wan spread her hands with interest, with a strange smile on her face. "Don't be nervous, this monster is nowhere near as powerful as you think, use your wits and use the spells you've learned, and you'll be able to solve it."

The strength of the cave giant is neither strong nor weak, and its destructive power is equivalent to that of a mid-to-high-level magician with a human, but its movements are clumsy and slow, and it is easy to defeat it as long as it is targeted with a targeted attack.

According to the grade level of Hogwarts school, students in grades 1 and 2 are equivalent to junior wizards, students in grades 3, 4, and 5 are equivalent to intermediate wizards, and students in grades 6 and 7 are equivalent to advanced wizards.

Further up there are the instructor-level magicians, and most of the professors in the school are at this level.

Tutor levels can also be divided into regular tutors and elite tutors.

Most adult mages are at the level of ordinary instructors, such as Professor Rolanda Hodge for the flying class, Professor Barsida Babling for the Ancient Magic class, and Professor Quirrell for the Defense Against the Dark Arts class.

Some powerful professors and Aurors of the Ministry of Magic can be considered elite-level, such as Severus Snape, the head of Slytherin House, Minerva McGonagall, the head of Gryffindor House, Sirius Black, Mad Eye Moody, and others.

Above the professor are the legendary magicians, and there are currently only three people in the entire wizarding world who have reached this level, the contemporary legendary white magician Albus Dumbledore, the contemporary legendary dark magician Lord Voldemort, and the contemporary legendary alchemist Nicol Lemay.

The founders who established Hogwarts School of Witchcraft and Wizardry and the four major houses can also be regarded as legendary, and their strength may be stronger than Dumbledore, or they may not be as strong as Dumbledore, because they are too old, there is no way to tell.

However, there is a magician whose strength can be determined to be above the legend---- Merlin.

Perhaps he could be called mythical.

The Cave Giant's weakness is very obvious, as long as you are not frightened by its terrifying appearance, you can defeat it with the strength of an intermediate mage.

"Don't be nervous, it's coming, it's up to you now. Come on, I'm optimistic about you. Wan Wan patted her on the shoulder and said with a wicked taste.

"Oh no, I'm going to be smashed into a patty by it." Hermione said loudly, turning around, only to find that Wanwan had disappeared, she immediately panicked and said loudly, "Where are you?" ”

"Don't be distracted in the face of the enemy, otherwise you will only die faster." Wan Wan's voice came from nowhere, and it came smoothly into her ears. "The strengths and weaknesses of the cave giants are equally obvious, they are powerful and slow in their movements. Don't be nervous, I'll protect you in secret. Think about the magic spells you know, there must be one that can deal with it. ”

Hearing Wanwan's voice, Hermione's mind slowed slightly, she took a deep breath, quickly went through the spell she knew in her head, drew her wand and waved it at the cave giant, and used the most powerful spell she knew: "Petrify!" ”

This spell is also known as the Petrification Charm, and she used it to petrify Neville Longbottom.

Hermione was a super top student, and she had learned all of the first-year "Standard Spells, Elementary" before entering the school.

I saw a faint green light flash away, and it quickly hit the cave giant.

The next moment, the cave giant stiffened and stood in the middle of the toilet as if it had turned into a stone, not moving.

"I made it!" Hermione exclaimed in surprise.

"Don't be happy so early, didn't you say that the cave giants have a very strong immunity to magic." Wan Wan's voice rang out.

"Click."

Then a cracking sound sounded.

The cave giant broke through the petrification spell, picked up the stick, and rushed towards her with his short legs.

"Ahh

A scream rang out.

Hermione was so frightened that she could almost breathe far away, and just as the cave giant was about to rush in front of her, a flash of inspiration flashed in her mind, and she quickly shook her wand and said, "Legs freeze and die." ”

This spell was also learned in first-year Charms class, and Malfoy used it to play Neville Longbottom.

"Phew!"

A ghostly light flashed.

As the cave giant sprinted forward, the two little short legs involuntarily merged together, and suddenly lost their balance and leaned forward.

"Whew!"

The cave giant's massive body thrust the mountain of gold and slammed it down towards Hermione, who was already too frightened to move.

Just then, a white figure appeared beside Hermione, lifted her petite body, and quickly walked away from the shadow of the cave giant.

"Bang!"

There was a thud.

The cave giant fell to the ground with a heavy blow, and the ground shook violently, and dust flew up.
