"Hermione, you're such a good girl." Looking at Hermione, who was crying in front of him, Bernard felt that Harry and Ron were stupid people, especially Ron.

"You're not wrong at all, it's a violation of discipline to travel at night, if you get caught, Harry and Ron will be miserable, and you and Neville are doing a good job, I didn't expect Neville to be so serious about completing the teacher's task, as for Ron and Harry, I'll make them look good in class tomorrow, you go back to sleep first." Bernard comforted softly.

"But what about Harry and Ron, teacher?" Hermione asked, sobbing.

"It's okay, I'll tell Professor McGonagall and she'll take care of it." Bernard said what he wanted, and he wanted to see what would happen to Ron and Harry if he intervened.

Seeing off Hermione, Bernard walked towards Professor McGonagall's office, but suddenly there was a flash of silver light, and Dumbledore's voice came out: "Something is wrong, come to the right corridor on the fourth floor." There was some anxiety in Dumbledore's tone.

What a coincidence! As soon as I was about to intervene, something went wrong, whether it was a coincidence or deliberate. Bernard paused and walked in the other direction.

……

On the other hand, Hermione, who had not waited for Professor McGonagall, followed Harry to the prize showroom on the third floor, and everything was as designed.

……

"You see, Bernard, it won't go in, I think it may have something to do with your arrangement." Dumbledore said as he looked at Bernard, who had arrived.

"Professor Dumbledore, I know what's going on, in my setup, evil spirits can't get close to this room, and I don't think a wizard who comes to grab the Philosopher's Stone will be a good wizard." Bernard looked at the troll that refused to come forward and said without thinking.

"Oh, it's a wonderful arrangement, it's a genius attention, but what now?" Dumbledore complimented at first, but then continued to ask.

"It's okay Professor, as long as I raised the lower limit of what can be judged evil, but it's clear that this troll's brain is much smarter than his kind, and while I just need to adjust it, it may take a while for it to get used to." Bernard said apologetically.

"It's okay, as long as we can solve the problem perfectly, we still have this time." When Dumbledore heard that the problem could be solved, he regained his composure and waved his wand, and the troll didn't know that Dumbledore had been transferred there, and then stood there like I see how you can solve it.

Seeing Dumbledore's style, Bernard did not hesitate, and waved his wand in the room, and with his wave, it seemed that some golden runes were extracted, and the white crystal also flashed several times.

When the dust settled, Bernard said to Dumbledore, "Professor Dumbledore, it's no problem now, and you can put the trolls in when the effects of the previous period of time have dissipated." ”

……

Gryffindor Tower, "Don't you see its feet?" Hermione snapped.

"Oh, come on, I can see enough of its head just by looking at it, you don't know how many heads it has." It was Ron's grumbling.

"Three, I saw it, and I also saw a trapdoor at its feet, and it had a role there, maybe it was a guard or something, well, now if you're all right, I'm going to go to bed, and I hope next time you won't involve me in this danger of death, or worse, be expelled." With that, Hermione pushed the door open and entered the girls' dormitory.

"She really can't tell the difference." Ron muttered.

……

"I'm very happy to meet you again, and today I want to check the results of your previous labor." Hearing this, many students panicked all of a sudden, and then calmed down, obviously feeling that there was no punishment at all, and it didn't matter if they couldn't carry it.

"Let's take a look, and the man I named stands up, Neville Longbottom." Bernard explained how to point out the first student.

"Don't be nervous about Neville, please tell the teacher, what is the conservation theory of matter?"

Neville finally finished his mind after a stutter, and although there was some discrepancy, he was right. "Very good, Mr. Longbottom, you have the right back, have faith in yourself! NextRon Weasley, what is the transformation of matter? After encouraging Neville, Bernard approached Ron

Although Ron pretended to be trying to remember, his red ears had already betrayed him, and Hermione had already made it clear to Bernard that he didn't memorize it at all, and not only that, but he also laughed at his classmates who tried hard to endorse, which made Bernard unbearable.

"Okay, won't it?! Mr. Weasley, please put away your disguise, sometimes it's cuter to admit than to pretend, and you should really take a good look at what you look like! A slightly harsh criticism of Ron was kind of a way to get Hermione and Neville back on the field.

Bernard turned to Harry and fired, "Next, Harry Potter, what is the isotope of gold?"

"Don't you know? Next ......" Bernard shook his head regretfully.

Finally, everyone was spot-checked, even Hermione was no exception, two Slytherins, Crabbe and Goyle, and there were more Gryffindors, except for Hermione and Neville, only Parvati answered the question alone, so to speak, Gryffindor was completely wiped out.

"Okay, good! According to what I said in the last lesson...... "This pause made the standing students scratch their ears and cheeks, and only when he saw this scene did Bernard continue to speak," these students who did not answer the questions will not be used for the rest of the lesson. ”

In a very flat but unquestionable tone, Bernard completely ignored the uproar of the students, and calmly announced the end of class and walked out of the classroom.

……

"Harry, take it easy, Professor Rochefort is obviously joking, you see the teacher often threatens us to expel us, isn't it okay! Just like last time you took a flying lesson, didn't you end up as a Gryffindor Seeker! Ron whispered to Harry.

At this moment, Hermione's voice came from behind, "You still don't understand, Professor Rochefort is obviously serious. Recalling the conversation just now, Hermione said with some irritation.

……

"Miss Granger, I'm sorry that Professor Dumbledore didn't come to inform Professor McGonagall when he suddenly came to me yesterday, and by the time the matter was done, you would have returned to the Gryffindor Tower." Professor Rochefort was visibly guilty, "But! There was no way for the teacher to regress on Harry's problem. ”

……

"What are you kidding? We are Hogwarts students and we have the right to take classes here. It was rare for Ron to say something that was on the right foot, but then Hermione's words completely shattered Harry and Ron's illusions.

"No, you don't know Professor Rochefort's determination at all, and he is clearly determined to punish you unruly students." With that, Hermione didn't say much to them, and strode forward, leaving Harry and Ron looking at each other.

……

They soon realized that Bernard's words were not a joke, because they would not be able to enter the alchemy classroom at all in the next class, and an invisible force blocked them, and in the end, it was Dumbledore who stepped in to solve the problem, but each student who did not complete the task had to copy "Alchemy Linguistics" and "A Preliminary Study of Alchemy Mysteries" ten times. At this point, the matter came to an end, and Bernard became the most unsympathetic teacher in everyone's mouth, far more terrifying than Professor McGonagall and Professor Snape.
