The mountain monster looked at the wooden stick with a bare handle in his hand with some confusion, and seemed to be a little puzzled why his originally thick and long wooden stick had suddenly become like this.

However, in the next second, a scorching orange light slammed into its face with a violent magic!

"...... Thunderbolt Explosion!"

Mu Yan's voice came from outside, steady and calm, as if he was just taking an ordinary spell class, his tone was not slow or hurried, and he bit every rise and fall of the spell very clearly!

Like a sound of redemption, the calmness and calmness in Mu Yan's voice made the three children who fell into panic subconsciously have an illusion of "we are saved"!

Almost subconsciously, they chose to trust and rely on the owner of the voice, completely unaware that this person was just a child of the same age as them!

"Mu Yan!"

Harry, who was still being carried upside down, looked out the door with the joy of the rest of his life, but just happened to see Mu Yan straighten his black wizard's robe and turn away.

Roar!

The mountain monster let out an angry roar, dropped Harry, and strode towards Mu Yan who had left!

Looking at the intact appearance on the mountain monster's face, Mu Yan's blow to the bull's-eye just now failed to bring it any damage!

Mu Yan immediately turned around and left without looking back after releasing the blasting spell, without any hesitation.

The moment the Demolition Spell hit the mountain monster's head, the sharp mental power had already fed back the results of the attack into his mind - almost no effect on the mountain monster!

This was already the most powerful mid-level spell he had ever come into contact with, and the loss of this blow made him suddenly realize that there was another shortcoming of this world's magic - the limited damage of pure magic magic!

Due to the unique huge magical power of the wizards of this world, coupled with their extremely weak mental power, the wizards of this world are almost the opposite of the other magical worlds in terms of the system of spiritual power models and spells.

From the perspective of "Corrosive Mist", the magic of other worlds focuses more on the construction of mental power models and less reliance on spells, but this world is more focused on relying on spells and ignores the huge development potential of mental power models.

This seems like a true misguideline, because spells can never be cast as fast as instantaneous magic!

This has also been reflected in Dumbledore and other high-level wizards, who have also chosen to use their mental power to build more detailed mental power models instead of casting spells when their mental power is strong enough to harness magical power.

But that's for high-level wizards, for low-level wizards, the extremely weak spiritual power makes them miserable in the construction of the mental power model, and spell cooperation is their only way out.

As a result, this also leads to another side effect - the magic of this world rarely uses magical elements!

The reason is simple.

The weak mental power of the wizards in this world can hardly build a more precise mental power model, and the communication and use of each magic element for magic elements must basically be completed through the mental power model, these things cannot be done by spells alone. Wizards who can't get more power from the natural world have to find another way out of themselves, and in the end, their own vast magic power naturally becomes their only choice.

There are pros and cons to this approach, the advantage is that its own magic power is easier to control, but the disadvantage is that it lacks the assistance of magic elements, and the magic of this world is greatly weakened in all aspects! In the face of those thick-skinned guys, the magic made of pure magic can barely penetrate the opponent's body!

Mu Yan turned into a passage, but his face did not show any disappointed expression.

The other party was an adult mountain monster, and he had expected that he would not be able to cause considerable damage to it, although the situation was even worse than he thought, and his attack did not leave even a trace on it, but this did not affect his next plans.

On the way here, he had figured out how to deal with the worst-case scenario.

Although he can also choose to escape, the structure of Hogwarts is not complicated, but it is already a labyrinth for a brainless fool like the mountain monster.

But with the thought that this was a rare plus for his contribution to Hogwarts, and with the idea of not giving Harry's trio a chance, he decided to try to see if he could get the stupid guy on his own!

Walking in the passage that was not very long, Mu Yan walked quickly, but there was no trace of panic.

"Twelve...... A baker's dozen...... Fourteen ......"

"Fifteen!"

Silently reciting in his heart, the last number, Mu Yan just stepped out of the corridor and walked into a wide hall.

The hall is circular in shape, with three passages leading to Hogwarts Hall, the Hufflepuff quarters, and the Forbidden Forest, with a stone statue holding a wand in the center.

"Probably...... About three meters! Mu Yan turned around and pointed his wand at the tenth step he counted.

"Obstacles...... Obstacles...... Obstacles! ”

Three obstacle spells sounded in a row! At the tenth step, an invisible threshold crept across.

Overlap cast! This is the spell-casting technique that Mu Yan learned from Professor Flitwick, which can be used to increase the power of a spell that has already been cast by stacking the same effect on top of a spell that has already been cast!

After seeing the terrifying power and magic resistance of the mountain monster, in order to avoid the embarrassing thing of being directly knocked away by it because of his many obstacles, Mu Yan had to sacrifice a little bit of his already small magic power in advance, and superimposed two obstacles in a row.

The rumbling footsteps were already approaching the passageway, and the sound of the walls and pillars blocking the way being smashed could be heard from afar.

After estimating the time, Mu Yan turned to look at the statue of Helga Hufflepuff in a robe and a wand held high in the center of the hall, and bowed slightly apologetically.

"I'm sorry Mr. Helga, I think I'll fix you perfectly in a moment!"

He took a deep breath and waved his wand: "Yugadim Leviosa ......"

Rumble!

The stone statue floated slowly in the vibration!

Mu Yan suddenly felt his hand sink suddenly, and his wand seemed to be suddenly hung with more than a dozen lead balls, almost falling to the ground all at once!

He obviously didn't expect this situation either, and when he was stunned, the stone statue suddenly tilted in the air......

Knowing that now is not the time to be indecisive, Mu Yan gritted his teeth, and the magic power poured out of his wand like he didn't want money, which was able to stabilize the stone statue and not let it fall.

Under the control of Mu Yan's wand, this stone statue that has stood for an unknown number of years floated crookedly all the way to the direction of the passage as if it was drunk......

At this time, Mu Yan's heart was extremely painful - prying such a large and heavy stone statue, the magic power consumed every second almost made him want to vomit blood!

One minute! He clearly understood that with his magic power, he could only hold on for a minute at most!

If the mountain monster hadn't arrived after a minute, he would have had to flee.

"You'd better run faster!" Mu Yan only felt that his heart was crying, and for the first time in his heart, he had a feeling of hatred for the speed of his enemy!

Fortunately, the mountain monster did not live up to Mu Yan's painstaking efforts, and two seconds later, it roared and appeared at the entrance of the passage at the other end!

The enemies are very red when they see each other!

The mountain monster roared and rushed towards Mu Yan, his simple and dull brain didn't give him time to think about what Mu Yan's strange posture meant!

Mu Yan walked a distance of ten steps, and the mountain monster only took three steps!

After three steps......

The mountain monster suddenly felt that something hard under its feet tripped over it, and then it was carried "flying" by the power that it had no time to retract!

The world around it began to tip rapidly, and the ground paved with cyan tiles quickly enlarged in front of it!

Boom!

The smoke and dust filled the air, and the mountain monster slammed into the ground, its twelve-foot-tall body almost instantly covering the rest of the passage.

Its neck stretched out of the mouth of the passage, and smashed its head on the ground, just touching Mu Yan's toes!

There were gold stars in his eyes, but the mountain monster still saw the human in front of him clearly, black wizard boots, neat wizard robes, no dirty hairstyle, except for the big drops of sweat on his face, he looked like a wizard who had just been tidied up and was ready to go out!

This is the little wizard who gave it a slap in the face! The mountain monster was extremely sure in its heart, although it couldn't remember the man's face clearly, but it remembered his taste!

That's right, it's him!

The flames of anger suddenly gave it the strength to get back to its feet, and it was trying to straighten up with its arms propped up, and it was going to crush the ant into pieces and eat it piece by piece!

It roared angrily,

But there was a wheezing voice from the little wizard in his ears:

"Halloween...... Happy! ”

Halloween?

In the whistling,

Huge stone statues fall from the sky!

……

"Please explain why you're here!" Professor McGonagall and Snape and Chino bumped into Harry and the others outside the women's restroom door.

The three of them originally planned to catch up with the mountain monster to help Mu Yan, but they didn't expect to be caught here.

"Because...... We thought Hermione was still in the bathroom......" Ron quickly explained.

"None of this matters, okay?" Harry hurriedly interrupted Ron, "Mu Yan is still being chased by the mountain monsters!" We're going to get him to his rescue! ”

"What do you say? Mu Yan is being chased by mountain monsters? Professor McGonagall raised her voice in fright!

The word mountain monster is already very impactful, and with the addition of Mu Yan, the hearts of the three professors are tightened, and there is a chase behind them......

Professor McGonagall stated that she had not been frightened like this in many years.

Snape was the quickest of the three, and he immediately drew his wand and cast a directional spell, although he couldn't target the mountain monster, it was still easy to orient Mu Yan!

A thin ray of light shot out of the wand and pointed in one direction.

The three professors hurried to follow.

Harry and the three looked at each other and quickly followed......

Broken pillars and cracked wall tiles were everywhere, and the rumbling footsteps of mountain monsters could already be heard clearly!

The crowd hurriedly quickened their pace.

Roar –

After a while, the roar of the mountain monster echoed in the space one after another, and the joy and tyranny in it made the hearts of all the professors tighten, and a bad premonition rose in their hearts at the same time!

"Echo...... Echo...... In that passage! Hermione was the first to determine the direction in which the voice was coming from.

The sound of the mountain monster's running footsteps......

The ground trembled with a roar......

The crowd rushed to the entrance of the passage with all their might, and they turned around panting, and pulled out their wands.

Then, in their incredulous gaze,

Huge stone statues fall from the sky!

Rumble!

Smoke and dust,

In the flying stone chips, Mu Yan slowly inserted his wand back into his waist,

The face is modest, the demeanor is respectful,

Like a warrior who has just completed a duel and returned his sword to its sheath!
