HP: After binding to the strongest wizard development system

It was already dinner time when Till returned to the castle. She came to the restaurant with a cold body, and was shaken by Snape's hand: "I haven't seen you all day, is it cold?"

"Fortunately, I had a lot of fun." Till summed up everything today into one word - play. If Lucius Malfoy and the others heard this, they would be so angry that they would not be able to sleep at all tonight.

The Christmas vacation has ended, and the students have returned to Hogwarts study life well, but they still have a hard time accepting the love between Till and Snape.

Some of the Slytherin students looked the weirdest.

When Till sat on the professor's chair, he glanced over there a few times and recognized the descendants of several pure-blood family heads today, and Draco Malfoy was one of them.

"Look at those little Slytherins, the way they look at me really makes me want to eat." Tyr admired their surprised and angry expressions for a while, then ordered a beef stew on his plate. "I'm going to eat more tonight."

Professor Dumbledore seemed to look sideways at Tyr, but he quickly looked away and looked at the empty seat next to Flitwick: "If something happens to Quirrell, who will take over his teaching for the next six months?"

Several professors were originally talking to each other in a pleasant atmosphere, but after listening to Professor Dumbledore's words, they lowered their heads in unison without even looking at Professor Dumbledore.

Just kidding, they are already tired enough from attending classes. If they take another class for themselves, they might as well stop resting.

Professor Dumbledore smiled and went directly to see Teal and Snape.

This is an unmarried couple. One of them is the most idle professor at present, and he only has two classes a week. The other was Professor Dumbledore's usual substitute professor. Every year after the Defense Against the Dark Arts professor's accident, Snape would take over.

"I'll do it." Tier frowned and took the initiative to take over the matter.

Snape was already busy enough. Although Teal was busy laying a dragnet against Voldemort, the people under his command were the ones doing the work. Teal himself still had a lot of free time.

Before Snape could object, Professor Dumbledore applauded and settled the matter. Snape reluctantly shook Teal's hand and said, "I keep all my previous preparation books and will take them later." Your office."

Snape has been teaching at Hogwarts for seven or eight years, and has taught Defense Against the Dark Arts for seven or eight years. The preparation books for each grade are piled in the corner of his office, so there is no need to ask Till to bother with it. I re-prepared my lessons bit by bit.

"Thank you Severus." Teal winked at Snape and followed him underground after dinner. There was no need for Snape to make a special trip later, she could just float back with the book.

The fireplace in the underground office was burning with hot flames. Thiel liked the warm environment very much. He sat down on the small sofa with ease and stretched out his hand to reach the blanket on the chair next to him.

Before the blanket could be reached, Till's attention was first attracted by a large stack of notes on the small table next to the sofa.

"You really studied it." Tier blushed and didn't dare to read the first few words. He lowered his head and carefully covered himself with the blanket.

That large pile of notes were all about Snape's research on contraceptive potions.

Teal thought that Snape was just saying it casually to tease her, but now it seems that her fiancé is serious.

"Of course." Snape walked over, put the large pile of notes on his lap without any restraint, and even started to communicate with Teal.

Till didn't mind the discussion about potions, but she looked at Snape's serious profile and suddenly leaned over and kissed him: "You drink the contraceptive potion last, what about me?"

Not long after this, Snape's general idea had been determined, and Till couldn't help but sigh at Snape's efficiency in this matter.

"Miss Emery-" Snape took a deep breath and looked at the teasing Till with a deep look, "Just enjoy it."

Teal's joking look could not be maintained under Snape's straightforward words. She found that compared to the unruly Snape, such a serious Snape made her even more intolerable.

Tyr blushed and patted Snape's chest, turned away and ignored him. Snape saw Till's shyness, smiled softly and kissed the corner of Till's mouth, then stood up to find the preparation book for the Defense Against the Dark Arts class.

"The Defense Against the Dark Arts class is not easy, but the basics of the students are pretty much the same." Snape took out a box and placed it in front of Teal.

This was a serious matter. Thiel turned to him and asked: "How is the basics?"

"It's all terrible." Snape didn't even raise his head, his tone full of ridicule, "There is no stable professor teaching so far. The students have to learn intermittently. It's strange that the basics are good."

Teal touched his nose and finally understood why the pass rate of Hogwarts' Defense Against the Dark Arts class was not even as good as Snape's Potions.

Snape waved his hand: "No professor can teach for more than one year, either due to accidents or temporary absences."

"Because of Voldemort's curse?" Till knew this statement, and every year the Defense Against the Dark Arts professor confirmed the authenticity of this statement.

Snape shrugged noncommittally.

Teal picked up a textbook. Snape's records in it were very neat and complete. She thought of Snape's long-standing expectations again: "I remember that you were always applying to Professor Dumbledore to teach Defense Against the Dark Arts. s position."

"Not anymore." Snape sat back down next to Teal and told her about the matter. "Although I really want to be a Defense Against the Dark Arts professor, I'm used to Potions. If I were asked to give up this course, I would be reluctant to do so.”

Snape added: "And my application for the Defense Against the Dark Arts course was actually under the instruction of Professor Dumbledore."

This was the first time that Till knew the inside story of this matter, but after thinking about it, he understood Professor Dumbledore's intention.

Snape's previous identity as a Death Eater was real, but after the fall of Voldemort, he became Professor Dumbledore's, served as Potions Professor at Hogwarts, and became the Dean of Slytherin. , if Voldemort returns one day, his first doubt will definitely be Snape's reliability.

The competition for the position of Professor of Defense Against the Dark Arts is an illusion given to the outside world by Snape and Professor Dumbledore - although Professor Dumbledore believed in Snape, he did not completely trust Snape and was unwilling to Give him such an important position as Defense Against the Dark Arts.

It even made everyone think that Professor Dumbledore had been wary of Snape and did not want Snape to recall his former desire for black magic and become an "evil dark wizard" because he officially taught Defense Against the Dark Arts. ".

But there is no need to maintain this illusion now. Voldemort already knows about Snape's betrayal. Even if Snape comes up with a perfect excuse to join him, he will no longer have the same confidant status as before.

In Voldemort's mind at this time, Snape was already a complete opponent.
