The cold and wet corridor was dead silent, and everyone's eyes fell on Siwen, who was standing in front of the ice crystals.

Siwen was circling around and observing his surroundings, though most of the clues had been destroyed by the footprints of the students who had poured into the hallway.

But the traces of that magic can still be seen. For example, the clear water in the ice crystals unleashes several ice hockey spells in the corridor, and the straight line attack and the aoe effect of the ice ball can block the entire corridor.

Then there was the unmelted ice on the wall and floor, the ice pick, the armor-piercing spell, and it was clear that she had encountered a very difficult enemy.

Looking down further, the traces of the explosion, unexpectedly, she had actually mastered the latest magic she had taught her, the Frost Rocket.

Frost Rocket, a magic that combines ice and fire magic. Extremely penetrating and unstable, it will cause a violent explosion after a collision, causing secondary damage.

Finally, there is this ice crystal, an ice barrier imbued with the power of the laws of the ice system, which triggers her instinctive protective reaction in the event of death.

Wait, what is this? Siwen looked at the upper section of the ice crystals, and it seemed that something was moving.

A gray force was eroding the dazzling blue of the ice crystals, heading towards her head. If it is not treated, maybe in a few more hours, it will cause her damage, irreparable damage.

And in other parts of the ice crystal, there are some slight breaks, what kind of physical attack can shatter this magic ice crystal?

Dumbledore took out his wand and waved it lightly near the ice crystals, a faint silvery-white mist fluttering, and a tyrannical aura gradually converged, which was the breath of the attacker.

"Ah, this gray power, I think I've seen it in the clock tower of London. Dumbledore looked very interested, "This is the ultimate power of petrified magic, full of gray power"

"But this tyrannical aura doesn't belong to a sapient creature capable of using spells, maybe it's innate instinctive magic?" Dumbledore muttered to himself.

"Harry?" Sivin beckoned to him as he looked pale and had stood in the water for too long, his shoes and the hem of his robe soaking wet, and motioned for him to come over.

"Did you see or hear anything?" Dumbledore's wand had dried Harry's body and his clothes and shoes dry again.

"Thank you, Professor......" Harry hesitated, remembering that Ron had said that it was not a good thing to hear voices that others could not hear, whether in the Muggle world or the wizarding world.

"Professor, I'...... I had just left Professor Lockhart's office, and the confinement was not over because of a mistake at the beginning of the school year.

When I walked to this corridor, I first saw who was flowing on the ground, and I heard a faint sound of spells, and the sound of collisions, and when I arrived here, Senior Sister Shimizu was already like this. ”

Lockhart, the peacock, nodded like a kowtow worm to the side: "Yes, yes, Harry just left my office, oh, there are so many replies from those enthusiastic book friends......"

Snape interrupted Lockhart impatiently, staring at Harry like an eagle on its prey, "I have a question, Potter, it doesn't seem to be on the line between Gryffindor Tower and Lockhart's office." ”

Harry was a little dumbfounded and didn't know how to answer, his face turned a lot paler, and he looked at the senior sister who was frozen in the ice crystals: "I ...... I...... I heard strange noises. ”

Harry exhaled deeply, feeling his body suddenly relax a lot, "I've heard voices inside that wall many times, hoarse voices like shouting kill, kill, kill or something.

I just followed that voice and ran all the way to here. I don't know what that sound is, sorry, I didn't have time to help Senpai. ”

Looking at Harry's guilty eyes, Sivin patted little Harry's hair: "It's okay, at least you can help us find the clue as soon as possible, right?" ”

"Wall, Albus......" Professor McGonagall looked at Professor Dumbledore in confusion, the old man's blue eyes glinting under the semicircular lenses.

Headmaster Albus Dumbledore stood in front of this wall, raised his hands and whispered, "Longing, Rust, Seventeen, Dawn, Furnace, Nine, Goodness, Homecoming, One, Wagon, Hogwarts Obey My Will." ”

The walls began to flip like the walls of Diagon Alley, revealing the hidden structure behind it, which made those present gasp.

Intricate copper pipes weave through the walls of Hogwarts. It exudes the color of dark years.

"Pipes, what's hidden in there?" The crowd clearly felt the same furious, tyrannical aura that Professor Dumbledore had condensed near the ice crystals.

Next to the broken wall was a line of bright red handwriting: "Beware, enemy of the Inheritor! ”

Dumbledore looked at the brass and then at the line of handwriting, as if he was thinking, as if he was remembering something.

"Hear strange sounds that no one else can hear, Harry Potter, tsk. Snape said angrily.

He looked at Professor Dumbledore, "Headmaster, I think it's likely that our Mr. Potter has been attacked by the Dark Arts, disrupting his mind and in need of a thorough examination. ”

"Professor, I'm ......"

"Alright, Harry, and Mr. Weasley, Miss Granger, I think you need to go to bed early, Miss Charlotte, please accompany them and escort them back. ”

Dumbledore waved his hand, ignoring the little wizard's barely audible protests, and continued to keep an eye on the scene of the crime.

"Petrified to such an extent that in legend only powerful wizards or magical creatures, such as the Gorgons, such as the Basilisk, also have the power that has been cursed by the gods. ”

"The Chamber ......of Secrets," Sivin seemed to muse, "the one that was established by Slytherin's radical minds, purportedly used to purify this secret room of Muggle wizards and half-blood wizards?"

"According to legend, this is true, but it is a pity that none of the headmasters up to me have discovered the existence of that secret room. On the contrary, the existence of the Room of Requirement has become an almost open secret. ”

Dumbledore looked at the ice crystal, "Mr. Swift, I don't know how our Qing Shui classmate was able to break away from this.

If I'm not mistaken, this must have been the last protection for the ice mages in ancient times when their lives were violently threatened, right?"

"Senior Sister Qingshui's Ice Barrier power is not entirely from herself, but also from some outside forces. Xiwen pointed to the pale blue necklace pendant on Qing Shui's chest, which contained a permafrost ice crystal with a complete law.

"If I can wake her up on her own, it will be of great help to her magic comprehension, and I will always keep an eye on her life and break the ice immediately if it is not good. This is also the responsibility of a student council president to his classmates."

With the consent of the professors, Xiwen put his hand on the ice crystal and disappeared into the hallway, leaving only the professors looking at each other.
