"No rush, you can take your time looking. Oh, and based on the dangerous things you've done before, I've realized you're not exactly harmless, so here's this for you." Kaisen comforted him while summoning an ender pearl.
"If you encounter danger you can't handle, just smash this thing, and I'll appear before you. It works even in Hogwarts; this isn't within the scope of Apparition."
Neville, blushing, took the ender pearl and then realized an awkward problem: he had forgotten to bring a gift.
Harry noticed Neville's embarrassment and changed the subject for him, saying, "By the way, Professor, are you planning to attend tonight's Halloween feast?"
Kaisen looked at the calendar propped on the table and suddenly realized, "Time flies so fast. No wonder Professor Sprout asked me about my makeup first; she thought I was trying on a costume."
"Then will Professor go?" Neville asked, putting away the ender pearl.
"Don't worry, I will, but you'll have to let me get myself ready. I haven't left my room in almost a day and a half." Kaisen spread his hands, and Harry and Neville quickly left the office.
With some free time, Kaisen put away the book containing the enchantment symbols for the ender pearl, walked deeper into the office, took a comfortable bath, and then opened his wardrobe to start primping.
Soon, Kaisen, wearing a dark purple robe, appeared at the Professor's table.
Actually, this robe was originally black, but Kaisen witnessed Cerberus breaking through Snape's defenses with one bite, and immediately lamented the dangers of Hogwarts, enchanting himself a set of battle Wizard robes overnight.
And at this moment, it could also serve as a formal robe.
"Honestly, the robe is excellent." Dumbledore said, looking at Kaisen's shimmering robe.
"Mhm, quite excellent."
"Perhaps you could help my socks... uh, you know, getting older always makes one sensitive to cold."
"I hope they're new socks."
"....."
"Impossible!"
"Alright." Dumbledore said, a little aggrieved.
Just as everything was peaceful, Professor Quirrell suddenly ran into the Great Hall, panting.
"Dumbledore! A Troll, there's a Troll in the Castle... ugh!" Quirrell choked and fainted at the end of his sentence.
"Looks like the Halloween party can't continue." Dumbledore complained softly, then stood up: "Little Wizardss of the four houses, follow your prefects and quickly return to your common rooms! Don't fall behind!"
"All Professors, now search every corner of the Castle and find this Troll."
"I bet Quirrell let him in. It's the thief crying 'stop thief'."
"I'm pleased to tell you, you guessed correctly." Dumbledore softly agreed.
"Merlin!"
Kaisen complained softly, then quickly pulled out his wand and left the Professor's seat, heading in the direction Quirrell had come from.
He walked slowly. Hogwarts was so vast; finding a Troll in it was, truthfully, by no means a simple task.
If nothing unexpected happened, it was possible to search all night.
Moreover, the Little Wizardss had all been evacuated back to their respective common rooms, so the only damage a Troll could cause was to the architecture.
Wouldn't that be his time to shine?
He had already thought it through: a grand architectural spectacle in front of all the Wizards in the school, to give Hogwarts a massive civil engineering shock.
Then he felt an ender pearl shatter, and the next moment he appeared in a somewhat dilapidated corridor. In front of him were two Little Wizardss.
Harry was slumped in a nearby corner, and Neville's leg was broken. He was looking at Kaisen, who had suddenly appeared, with a look of relief.
Then he frantically pointed behind him. Kaisen looked back and saw Ron trying to choke the Troll from behind, but unfortunately... Trolls don't have necks.
And Hermione in the corner, emmm, she must have been knocked out.
"Professor, look out!"
Someone shouted, he didn't know who, but the Troll noticed the Wizard who had suddenly appeared in front of him. Although his small brain couldn't understand how this Wizard had appeared here, he instinctively picked up his club and swung it.
Clang!
Kaisen stood his ground, taking the heavy blow head-on.
It wasn't that he was trying to maintain an air of superiority; it was simply... he hadn't reacted in time.
It was also fortunate that he had shamelessly enchanted his robe more than a dozen times before. This blow, which should have splattered brains, only made Kaisen feel as if someone had lightly tapped his head.
It didn't even break his defense.
"P-Professor, are you alright?"
Kaisen shook his head: "Ron, get away from here!"
Ron, seeing Kaisen arrive, also breathed a sigh of relief. He nimbly jumped off the Troll's back, picked up Hermione around the waist in two steps, and ran behind Kaisen.
Kaisen watched Ron and Hermione get far away, then relaxed. He lured the Troll into a corner of the corridor, and once it was in a suitable position, ensuring it wouldn't affect the four Little Wizardss, a block shimmering with white light appeared directly in his hand.
He slammed it into the Troll's chest, then quickly summoned an ender pearl and left the spot.
With a bang.
He appeared in front of Ron and Neville, and an obsidian wall blocked the blood and flesh exploded outwards.
"But, I have to say, this big guy really stinks."
Kaisen frowned, complaining. Then, with one in his left hand, one in his right, and another on his back, with Ron following behind, the five of them headed straight for the Medical Wing.
After handing all four Little Wizardss over to Madam Pomfrey, Kaisen finally found Dumbledore.
"You should have given Quirrell a bottle of Veritaserum. A Troll almost killed four Little Wizardss. Who knows, he might have let in more than one!"
Dumbledore patted Kaisen's shoulder reassuringly.
"Relax, relax. I've confirmed it; there was only one Troll, and that Troll has already been blown to smithereens by you. Just relax."
"That's for the best. But I still think you should keep Quirrell under control. If you're too embarrassed, I can bag him in the middle of the night. I guarantee his butt won't leave the wheelchair before the Christmas holidays."
Dumbledore looked at Kaisen somewhat strangely.
"I didn't realize you were so... radical. After all, you've always seemed quite laid-back before."
"Now he's throwing Trolls into Hogwarts, what else wouldn't he dare to do? At this point, should I still stand here and talk without consequence, saying, 'Quirrell is an innocent good person?'"
"He's already an enemy!"
Kaisen spoke with some agitation.
"I understand, I understand, but you can rest assured, truly."
