Roaming the universe, all thanks to your many dark skills!

Rosen felt that it was worth it to kill the troll just by getting this skill, and he also released the search potion and search item skills on the troll's body.

"Ding, you have obtained the giant monster's physical potion. After drinking it, you will randomly gain 8-15 points of physical strength, a permanent increase, and no side effects. The only thing you need to endure is its unpleasant smell."

For Rosen, this was a pleasant surprise.

Even if you are unlucky and just get 8 points of physical strength randomly, that is already pretty good.

Rosen was quite tempted, but he didn't plan to drink here. He lowered his head and glanced at the scene. His eyes fell on the huge wooden stick that the troll held until his death. An idea came to his mind, and he immediately went over and put it into the storage compartment.

"If you don't want to attract too much attention, let's leave as soon as possible while the professors outside are still blocked by the electric arc." Rosen turned his head and looked at Luo Youwei and Hermione behind him.

"Okay." Luo Youwei nodded.

"But there is only one exit from the bathroom. How can we leave without being seen by the professors?" Hermione asked curiously.

"It's very simple." Rosen said, and snapped his fingers.

Soon the three of them disappeared.

At this time, as the electric arc outside disappeared, Albus Dumbledore, Minerva McGonagall and other faculty members who had arrived long ago rushed into the bathroom, and Harry Potter and Ron Weasley, who had been worried about Luo Youwei and Hermione, also followed in secretly.

But what appeared in front of everyone was only a giant monster lying on the ground, dead, but there was no sign of a student.

"The person who killed it not only used lightning magic, but also fire magic."

Dumbledore did not dislike the strong stench on the troll and the strange smell caused by being roasted and struck by lightning. Instead, he came closer and carefully observed the wounds on the troll's body. Finally, he said: "The interesting thing is that I have almost never seen these magics before."

"I think I know who did this," said Minerva McGonagall, looking at the obvious burn marks on the troll's chest.

At the corner of a secluded corridor, Rosen, Luo Youwei and Hermione suddenly appeared.

"Do you want to go back to the dormitory now, or come to my place to eat something?" Rosen glanced at Luo Youwei and said, "You were busy fighting the giant monster just now. I'm afraid you didn't eat well, right?"

"Hehe." Luo Youwei stuck out her tongue, agreeing with what her father said.

Perhaps because she was frightened by the troll, or perhaps because she was still shocked by the teleportation that Rosen had just performed, Hermione Granger, who was always talkative and asked many questions, seemed like a different person at this moment and was quite silent.

"Hey, Hermione." Until Luo Youwei touched her with her arm and asked, "Do you want to go to my dad's house for something to eat?"

At this moment, Hermione woke up from her dream, smiled and nodded, "Okay."

So Rosen took them to his dormitory, lit a fire and cooked some noodles, then took out a few plates of sumptuous dishes from the storage compartment and placed them in front of them.

"After you finish eating, go back and wash up and go to bed." Rosen said.

Luo Youwei and Hermione each picked up their chopsticks or knives and forks and were about to start eating when the door suddenly rang.

"Just eat your food, don't worry about it." Rosen said, he stood up and opened the door, his eyes fixed immediately.

Just because standing at the door were Albus Dumbledore, Minerva McGonagall, Severus Snape, Professor Quirrell and others.

"Excuse me..." Rosen looked at Dumbledore in front of him and asked directly without any intention of beating around the bush: "What can I do for you?"

"Won't you invite us in?" Dumbledore asked with a smile.

"Please come in." Rosen opened the door, and several people walked in one after another. They were all stunned when they saw Luo Youwei and Hermione eating heartily at the table.

"Hello, principal, and professors." Luo Youwei and Hermione quickly stood up, not even bothering to wipe the oil off their lips, and greeted them.

"Hello." Dumbledore nodded with a smile and said, "You two should continue eating. Don't let us spoil your appetite."

Rosen asked them to sit down at the tea table in the inner room and made them a pot of black tea in a purple clay teapot.

"I don't like coffee, I only like Chinese black tea, please try it." Rosen picked up a teacup and said, "Please."

Dumbledore and the others picked up their teacups, took a sip, and immediately praised the delicious taste.

Rosen didn't care whether they were sincere or not. He just took it as sincere praise. Then he looked at Dumbledore and said, "Now can you tell me why you came here?"

"We are here just to confirm one thing." Minerva Magg looked at Rosen and said, "Did you kill the giant monster that just appeared in the girls' bathroom?"

"That's right." Rosen nodded and said, "As a school security guard, when a dangerous magical creature breaks into the campus and threatens the lives of the students, I should kill it to avoid causing more serious casualties."

As he spoke, he glanced at Dumbledore who was silent beside him and said, "I am doing this completely out of duty. There shouldn't be any problem, right?"

"No, of course not. You did a great job and deserve praise." Dumbledore looked at Rosen with a smile and said, "I'm just a little curious. Where did you learn the magic you used? Can you tell me about it?"

Before he finished speaking, Rosen's mind was touched, as if an invisible force was trying to spy on his heart.

At the same time, a blood-red system prompt popped up.

"Albus Dumbledore attempted to use the Legilimency spell to probe the secrets hidden in your mind. Do you want to isolate him from this investigation and punish him severely?"

"Yes."

The next moment, Dumbledore, who had been smiling, suddenly groaned, and his originally rosy face suddenly turned pale, and even the wrinkles on his face seemed to become much deeper in an instant.

In addition, the veins around his temples were bulging and his muscles were twitching constantly. It was obvious that he was in great pain at this moment.

When Rosen saw this scene, he thought to himself that it served him right, but he did not intend to give up.

After all, he has never been the kind of person who would keep silent after suffering a loss, and what does the system's punishment have to do with him?

This kind of thing needs to be treated separately.

So, Rosen looked at Dumbledore and directly activated the Level 6 Mind Hammer.

Bang.

Although 7-10 points of normal damage and 7-10 points of magic damage can easily kill an ordinary person, they are not enough to cause fatal damage to Dumbledore.

After all, although he looks like he is about to die, he is still able to calm the entire magical world where demons are rampant. This is enough to show that he is by no means old and useless, but is still strong and should not be taken lightly.

However, the mental impact brought by the invisible hammer condensed by Rosen's spiritual power would definitely not make Dumbledore feel good.

After a slight cry, Dumbledore's eyes instantly turned blood red, which was caused by the rupture of many capillaries.

In addition, two streams of blood flowed silently from his nostrils, not only staining his robe red, but also splashing onto the ground, leaving a shocking scarlet color.

At the same time, with a sound like that of a ball being hit, Dumbledore involuntarily slid back two meters before stopping.

This is the knockback effect of the Mind Hammer, 100% triggering, irresistible, and has the power of rules.
