The sound of gunfire and the Troll's collapse eventually attracted the professors who came running.

After hearing footsteps, Chen Yu thought it over and decided to deactivate his invisibility.

Why not sneak away?

Of course, it was to complete the main quest: 【Main Quest: The Most Dazzling Kid in Hogwarts First Year】.

What could be more shocking than defeating a Troll and shooting another Troll?

Professor McGonagall jogged over to Chen Yu, looking at the two fallen Trolls, her eyes shifting from cold anger to shock.

She was angry at the Little Wizards' disobedience, thinking it was another brat who didn't know his place and disregarded the professors' instructions, but then she was shocked that this child had actually managed to take down two Trolls.

She covered her mouth in disbelief: "Merlin's beard! You actually defeated two Trolls! You even killed one of them, this is simply incredible."

If it was just one Troll, it could be called a coincidence, but to deal with two Trolls at once undoubtedly proved the strength of the Little Wizards in front of her.

Professor Quirrell, who followed closely behind, seemed startled by the Troll's corpse, trembling all over, and his gaze towards Chen Yu began to flicker.

Professor Snape, after examining the condition of the two fallen Trolls, stood up and saw the gun in Chen Yu's hand, his cold eyes fixed on him as he said, "Bringing dangerous Muggle items into Hogwarts, Gryffindor loses 5 points."

Chen Yu deactivated the Transfiguration on the handgun, turning it back into a piece of rotten wood, then explained to Professor Snape, "This was just made with Transfiguration, it's not a Muggle item."

"Then you should have listened to the professors and obediently returned to your common room, instead of recklessly challenging Trolls beyond your capability!"

"But I succeeded, didn't I?" Chen Yu retorted, "I didn't see Hermione at the feast in the Great Hall, and I was worried she didn't know about the Troll entering the school, so I specifically came to look for her."

Hearing the news about Hermione, Professor McGonagall was almost frantic with worry.

She hadn't realized that there were still Little Wizards who hadn't received the news of the Troll attack, and she immediately asked Chen Yu, "Are you sure Hermione wasn't in the Great Hall at the time?"

Chen Yu nodded.

Professor McGonagall couldn't help but shriek, "Quick! Find Hermione immediately! There isn't just these two Trolls that invaded!"

Chen Yu looked up in surprise at Professor McGonagall: "What? There are more Trolls?"

Professor McGonagall glanced at the still unconscious Troll, immediately cast a Sleeping Charm on it to make it sleep longer, and quickly added, "In fact, we found traces of three Trolls in the basement!"

Hearing that there were still Trolls, Chen Yu quickly ran to the fourth floor.

The professors followed closely behind, without even having time to ask about Hermione's whereabouts.

When they reached the fourth floor, Chen Yu saw the lavatory door in splinters and the area a mess, and he knew Hermione must have already encountered a Troll.

The professors also saw the tragic state of the lavatory, their faces changing as they rushed inside.

By the time Chen Yu and the professors reached the girls' lavatory, they saw Harry pulling his wand out of the fallen Troll's nostril with a look of disgust.

Professor McGonagall looked at the two unharmed Little Wizards, not seeing Hermione hiding in the shadows.

While feeling relieved, her eyes were also incredibly stern: "Merlin above, why are you two here! Shouldn't you be in your common room right now? You're lucky you weren't killed by the Troll!"

Concern made her frantic; Professor McGonagall couldn't imagine what would happen if Harry had been killed by the Troll.

Professor Snape bent down to check on the unconscious Troll, then fixed Harry with an intense gaze.

At this moment, Hermione, who was hiding in the shadows, finally struggled to her feet and explained, "Please don't, Professor—they were all because of me..."

Before Hermione could finish, Professor McGonagall interrupted her: "I know, Chen Yu already told me that you weren't at the feast and didn't know about the Troll attack. Did Harry and Ron come to inform you and then run into the Troll? But you shouldn't have faced the Troll alone, that's a very dangerous thing! One careless mistake could cost you your life! When you found the Troll, you should have run away to inform a professor, not tried to deal with him like Chen Yu!"

Hermione glanced at Chen Yu in surprise, then continued, "Yes, Professor. But it was too urgent at the time. I accidentally angered the Troll, and when they arrived, the Troll was about to swallow me whole. There was no time to find anyone. If Harry hadn't stuck his wand up the Troll's nostril, and Ron hadn't used the Levitation Charm to control the Troll's club and knock it out, I would definitely be dead by now."

After speaking, Hermione hung her head in shame.

Harry and Ron couldn't say a word; they hadn't expected Hermione to take all the blame upon herself.

Hermione had always been a good child in the professors' eyes, so taking the blame upon herself was as exaggerated as Snape suddenly being kind to Harry.

Seeing Hermione's good attitude in admitting her mistake, and then looking at Harry, Ron, and Chen Yu, Professor McGonagall said exasperatedly, "By rights, all four of you, for disobeying the professors' arrangements and running out on your own, should have house points deducted! But Hermione was uninformed when the announcement was made, and Chen Yu, Harry, and Ron violated the rules to inform Hermione. Therefore, no points will be deducted this time. What do you think, Professor Snape, Professor Quirrell?"

Professor Quirrell nodded tremblingly, clutching his chest, and walked out with faltering steps.

He seemed to have been quite frightened by the Troll.

Oscar wouldn't give Professor Quirrell an award for his acting, it would be a disservice to him.

Professor Snape, seeing that Harry and the others were unharmed, simply dropped a curt "Whatever" and, with an expressionless face, quickly exited the lavatory like a large bat.

Seeing the other professors leave, Professor McGonagall continued to speak to Chen Yu and the others, "If you're not injured, you'd best return to the Great Hall. Now that the crisis is over, the students should continue to enjoy the Halloween feast."

Then Professor McGonagall changed her tone: "You are all very lucky; few first-year students are able to contend with an adult Troll. Especially Chen Yu, you dealt with two Trolls and killed one of them. While I do not condone your actions, I am still proud of your bravery. All three of you have earned five points for Gryffindor, and Chen Yu has earned ten points. I will inform Professor Dumbledore of this matter. Now you may go; I still need to stay and deal with this unconscious Troll."

When Chen Yu heard Professor McGonagall say she would inform Professor Dumbledore, his heart still fluttered.

Then he realized that he had already learned Occlumency, and he was no longer afraid of Dumbledore secretly using Legilimency to probe his thoughts, so what was there to be afraid of?

Hearing Professor McGonagall tell them to leave, Hermione, Ron, and Harry hurriedly left the scene.

As Chen Yu was about to exit the lavatory, he heard Professor McGonagall's private warning to him.

"Chen Yu, come to my office after Halloween."

"And don't tell anyone about how you used a gun to kill the Troll."

Chen Yu paused, nodded at Professor McGonagall, and then walked out of the lavatory.

Walking down the third-floor corridor, Chen Yu did not see the two fallen Trolls.

Professor Snape or Professor Quirrell must have cleared the Trolls away ahead of time.

"Chen Yu, how much longer are you going to wear that ridiculous bubble?"

With the crisis over, Ron, seeing Chen Yu arrive with the Bubblehead Charm still over his head, couldn't help but complain.

Chen Yu rolled his eyes at Ron: "Until we leave the third floor. By the way, don't you guys smell the stench on yourselves?"

It was fine when no one reminded them, but as soon as someone did, they reacted.

Hearing Chen Yu's words, the three Little Wizards sniffed their clothes.

A foul stench rushed into their minds.

Hermione, Harry, and Ron instantly gagged.

Hermione was fine since she hadn't eaten much at the feast.

Ron and Harry immediately threw up everything they had eaten for dinner.

Ron, while throwing up, moved closer to Chen Yu, as if trying to get vomit on him.

"Damn it! Chen Yu, you must have reminded us on purpose!"

Chen Yu saw Ron approaching while throwing up and quickly started running forward.

Ron immediately followed suit.

Harry and Hermione, seeing Chen Yu and Ron run off, also quickly followed.

When the four left the third floor, Hermione quickly cast a Cleaning Charm on everyone to remove the stench from their bodies.

Upon reaching the Great Hall entrance, the three exchanged glances and simultaneously said, "Thank you."

Hermione was thanking Ron, Harry, and Chen Yu for coming to save her.

Harry and Ron were thanking Hermione for taking all the blame upon herself.

Sometimes, friendship is like that.

After experiencing something together, people become good friends.

And together, defeating a three or four-meter-tall Troll was an event memorable enough for everyone.
