Facing Cassandra's request, Cedric did not hesitate at all this time. He also stretched out his hand and shook it with Cassandra, saying:

"I am willing to join, not because I have no way out, but because I know that because of Grindelwald's last name and the position of leader of the Witch Party, Wentworth has no way out. I am willing to do everything I can for this damn friendship."

Seeing Cassandra and Cedric holding hands together, Green on the side couldn't help but clapping softly and said:

"It's really great, but it's a pity that I don't have a camera, otherwise I would definitely record this night and this scene!"

But just as Green finished speaking, he saw Cedric and Cassandra looking at him at the same time with strange expressions.

Green put down his hand somewhat angrily. Cassandra rolled her eyes and urged, "Hurry up!"

"Huh? What do you mean, hurry up?"

Green asked in confusion.

Cassandra frowned and said:

"Of course it's an unbreakable vow! Can't you see that both of us are ready?"

Hearing Cassandra's words, Green's eyes widened in surprise and he said, "Who told you that I can take the Unbreakable Vow? Even if I got 10 O.W.L.s, Hogwarts didn't teach the Unbreakable Vow!"

Hearing Green's answer, Cassandra couldn't help but widen her eyes as well, while Cedric on the side looked at Cassandra in surprise and said, "Cassandra, don't you know the Unbreakable Vow? You were the one who came up with this idea!"

Facing Cedric's question, Cassandra said with some annoyance: "I'm only in my second year at Hogwarts! Second year! Where can I learn the Unbreakable Vow? Besides, with my current magic power, I can't use it! Who would have thought that Green, as the head of Hufflepuff, doesn't know this spell!"

Green also said aggrievedly:

"There's no connection between prefects and spells!"

At this point, all three of them were deflated, and Cedric couldn't help but start thinking: "Okay, now there are two options. First, give up the so-called Unbreakable Vow. Second, find a place to learn the Unbreakable Vow in Hogwarts."

Hearing Cedric's words, Cassandra and Green looked at each other and said in unison: "Restricted Books Area!"

Cassandra immediately started to act. She said, "Green and I will find a way to sneak into the restricted area, and Cedric will keep watch for us outside the library!"

However, to their surprise, when Cassandra was assigning tasks to the three, a voice suddenly came from behind them, from the direction of the corridor: "Don't bother, I can help you perform the Unbreakable Vow!"

Faced with the sudden sound behind them, the three of them had no time to figure out who was behind them and reacted similarly at the same time.

As he pulled out his wand, he turned and pointed in the direction of the sound behind him.

Cedric: "Expelliarmus!"

Cassandra: "Faint!"

Green: "Everyone is petrified!"

If it were anyone else, they would have been caught in an instant, but unfortunately, the person standing behind them was Snape, the best dueling master in the entire wizarding world.

After easily dispelling the three people's spells, Snape's face was also moved, but he said:

At this moment, the three of them saw clearly that the person standing behind them was Professor Snape. Green smiled bitterly and gestured for Cedric and Cassandra to put down their wands.

Green, who had lived in Hogwarts for six years, knew that the three of them were no match for the professor in front of him, even though he taught Potions.

At the same time, Green said; "Professor Snape, actually, we are..."

But before Green could finish his words, Snape interrupted him and said, "I don't have time to listen to your stories! I know what you are going to do. I heard it clearly outside the door just now!"

Hearing Snape's words, Green couldn't help but let out a bitter smile, and responded: "Well, it seems that we still have a lot to learn! But who would have thought that a professor at Hogwarts would actually eavesdrop, right! So what are you going to do, Professor Snape!"

Snape ignored the sarcasm in Green's words and said directly: "I have already said that I can help you perform the Unbreakable Vow."

After hearing Snape's answer, the three of them looked at each other, but no one was naive enough to show a happy expression. After a moment of silence, Cassandra asked:

"So, what's the price, Dean?"

Snape's eyes swept across the faces of the three people one by one, and he said at the same time:

"I want you to protect one person. No matter what happens, you must ensure his safety!"

After hearing Snape's words, Cassandra, Green and Cedric exchanged glances. This time it was Cedric who spoke. Cedric asked:

"Professor, who do you want us to protect?"

Snape said word by word:

"Harry Potter!"

Hearing Snape's answer, Cedric breathed a sigh of relief. Fortunately, it was not someone he could not accept. However, Cassandra and Green frowned at the same time, because Snape's words made them think of a possibility at the same time.

So, Green asked tentatively: "Is it because that person is coming back?"

Snape did not hide his words and answered directly:

"yes!"

Hearing Snape's answer, Green fell silent, and Snape did not urge him. At this time, Cassandra stood up and said:

"We agreed!"

Green was about to say something, but Cassandra had obviously guessed what Green was going to say. She looked at Green and said:

"We are not playing games. This road is not easy to take. We already knew it a long time ago, didn't we? If that person really comes back, then we will have to face him sooner or later."

After saying that, Cassandra once again extended her hand to Green and Cedric, and asked, "Who will go first?"

Seeing this, Cedric was the first to come out and hold Cassandra. At the same time, Snape also came over, close to them, took out his wand, and pointed in the direction of the two people's hands! (End of this chapter)
