The person is at Hogwarts, but the system is in Middle-earth!

Headmaster Dumbledore's face was very serious, an expression that reminded Rowe of Gandalf's solemnity when facing the Balrog in the Moria Mines. He gently placed Colin Creevey in his arms on the bed.

"Petrification," Dumbledore said softly. "We won't be as lucky this time."

"Last time his camera saved him from disaster, this time..." He pointed to Colin's stiff fingers, which were still tightly clutching a new camera that looked secondhand, even with some paint chipping. But this time the camera wasn't burned, and the lens was still intact, because he had been petrified before he could even press the shutter.

"He saw it through the viewfinder," Rowe analyzed. "Scout Crevy was trying to capture an image of the enemy unit, but triggered the enemy's passive defense mechanism the moment he locked onto the target. But this time, the monster's magic was stronger, or it was closer."

"Look here." Professor McGonagall's voice trembled as she pointed to a bunch of flattened grapes scattered beside Colin's stiff hand. "He's here to visit Harry."

Luo Wei paused for a moment, the anger in his eyes subsided, replaced by a complex respect.

In his mind, the system automatically tagged the bunch of grapes:

[Item: Supply/Elf Fruit]

[Note: A brave hobbit crossed the enemy-occupied territory of the Ringwraiths to deliver this meager supply to the wounded Ringwraiths.]

"To deliver supplies to his wounded idol, he trekked alone through enemy-occupied territory..." Rowe's tone turned solemn as he looked at the bunch of grapes. "Though reckless, it truly is hobbit... no, Gryffindor courage. He had no weapons, no armor, only a bunch of grapes and a secondhand camera, yet he dared to walk through the dark corridors."

He sighed and bowed slightly to Colin's stiff body. "He was a fine man, just unlucky to have run into a patrolling Ringwraith. May Ilúvatar protect his dreams from shadows."

Harry lay in bed, watching the scene in agony. The crushed bunch of grapes made it hard for him to breathe.

"This is not the time for blame, Baggins," Dumbledore said, looking at Colin. "This confirms your suspicions once again. The Chamber of Secrets has indeed been opened, and the monster is becoming increasingly active."

He turned around and looked at Rowe, his blue eyes gleaming with a serious light.

"And you, Rowe. I know what you've been doing." Dumbledore's tone was calm, yet authoritative and solemn. "You've been following Harry around, trying to act as his bodyguard. Even tonight, you stayed here in that...unique way. I heard Madam Pomfrey complained that you insisted on sleeping in the spot closest to the door and arranged your slippers in a strange defensive formation."

Rowe straightened his back, his eyes unwavering: "Righteous followers need protection, Professor. This is my duty. If I don't stand guard at the door, who knows if a Death Eater might sneak in at night?"

"I admire your loyalty, Rowe." Dumbledore sighed. "A frying pan or a homemade smoke bomb would suffice."

"Therefore, we need to take the initiative!" Rowe countered. "We can't sit idly by, Professor! We need to find its lair before it turns the entire school into statues! If the flames of Gondor aren't lit, the Rohan cavalry will never come!"

"That's all I wanted to say," Dumbledore interrupted him, his tone turning stern. "Don't try to find it. Rowe, you and Harry, and Weasley, Miss Granger, I want you to stay away from this. This is beyond the purview of students. If you encounter that thing..."

He glanced at the stiff Colin, the poor kid still holding the camera.

"...Back then, even the best frying pan or smoke bomb couldn't save you. Some darkness, once touched, can never be returned to."

Rowe was silent for a moment. He looked at Dumbledore; according to the system's assessment, this was a high-level NPC in "Commander" status issuing a "retreat" order. But how could he possibly back down at this critical moment? Gandalf's orders weren't entirely correct!

But he nodded nonetheless: "I understand, Professor. We will be careful."

Dumbledore gave him a deep look, as if he saw through the hidden meaning behind his "be careful"—"I will be careful not to be discovered by you."

"Very well," Dumbledore said, deciding to trust the young man's promise for the time being. "Now, go back to your bed. Tonight has been messy enough. If Madam Pomfrey finds you still chatting, she'll kick me out too."

After the professors left, the ward returned to silence.

Lowe quietly retreated to his bedside. He didn't go to sleep immediately, but instead took out a small notebook he always carried with him from under his pillow—his "Haves and Monsters of Middle-earth." By the dim moonlight, he wrote a few words heavily on it with a quill pen.

[Enemy Unit Confirmed]

Target codename: Salazar's Nightmare/Basilisk

Danger Level: Morgoth Level (Extremely Deadly)

Feature analysis:

1. Fatal gaze: Direct eye contact can cause death, while indirect eye contact (through lenses/reflections/ghosts) can cause petrification.

Tactical Note: All reflective objects can be used as defensive equipment. It is recommended that all personnel be equipped with mirrored shields.

Evidence: Mrs. Lorris (reflection), Colin Crevy (lens).

2. Underground Sneak: Move through walls/pipes, and only the Ringbearer (Harry) can hear you (Parasitic).

Tactical Notes: The enemy has gained air superiority... no, ground superiority. They can appear anywhere at any time. We need sonar, or some kind of magic that can detect underground tremors.

Evidence: Harry's hearing, the spiders' mass exodus (spiders fear their natural enemies).

3. Weakness Speculation:

The crowing of a rooster? (Hagrid's killing of his rooster was an attempt to cover up the truth.)

A specific poison?

Gryffindor Sword (only epic weapons can penetrate dragon skin)?

Lowe drew a heavy red circle around the "rooster," then he put an asterisk next to the "pipe" and drew a crude skull next to it.

After finishing writing, Rowe closed the notebook and glanced at Harry beside him. Harry was staring blankly at the ceiling, clutching the corner of the blanket in his hand.

"Did you hear that, Harry?" Rowe crawled back into bed, tucking his wand under the pillow. "That rookie photographer took a knife for you. That's the second time. Colin Crevey, he may be a bit annoying at times, but he's a hero. Next time, that monster might come straight for you. After all, the Dark Lord always deals with the minions first, then the hero."

Harry turned and looked at Colin's stiff face, feeling a chill, but also a surge of anger: "We'll find it, Rowe. We will. For Colin, for everyone."

"Of course," Rowe's voice muffled from under the covers, "but before that, follow the 'survival first' protocol. Remember not to run around. Also, if you see anything that looks like a snake or a lizard, no matter how small it is, close your eyes first, then throw stones, and only then scream."

Good night, you who uphold the precepts. Tomorrow is another day full of hope!
