Three days later, Cynthia received a letter from Dumbledore, asking her to attend the Headmaster's office at noon the next day.

After lunch the next day, Cynthia went to the principal's office through the fireplace.

"Good afternoon, Professor Dumbledore!" As soon as she stepped out of the fireplace, Cynthia greeted an old man.

"Good afternoon, Thea! Would you like some lemon snow treasure? Dumbledore smiled and pulled out his favorites.

"No need, Professor! Is there something going on today? Cynthia hurriedly waved her hand.

"Well, okay. Severus found me the other day, you know? Dumbledore said regretfully.

"Severus? Is he looking for you? Cynthia frowned in confusion, and then instantly understood the reason. It's because of Lily, right? ”

"That's right, he begged me to protect her."

"He also came to me, but I turned him down." Cynthia raised an eyebrow. "So, you promised him?"

"Naturally, he gave me anything in return." Dumbledore said, looking at Cynthia's expression.

Sure enough, hearing this, Cynthia's face turned pale. "Anything? So, what are you going to do? Regarding the safety of Mr. and Mrs. Potter and Mr. and Mrs. Longbottom. ”

"We used the Loyalty Charm, I'm the Loombottoms' secret, and Siris is the Potters' secret." Dumbledore blinked.

"So, why did you call me over?" Cynthia looked at the smiling Dumbledore.

"I'm still not at ease, so I want you to help draw some protective formations." Dumbledore had a pleading look on his face.

"Formation? But is there already a curse of daring loyalty? And the confidential person is you and Siris, you should rest assured! There's no need to make any more formations. Cynthia looked at the old man puzzled.

"One more layer of insurance, I know you should know some protection formations."

"Professor......

"Thea, this is an order."

“…… That kind of formation, the guardian of the heart, do you know? Cynthia was silent for a long time.

"Guardian of the Heart?! Will you do this formation?! Dumbledore stood up in surprise.

"The Dark Lord, you gave me an ancient book before, which records this formation." Cynthia nodded.

"However, this formation ......" Dumbledore hesitated.

"Professor, you must know that this is the safest formation, and besides, I have successfully drawn it."

"When?"

“…… When Lily got married, I drew this formation for Severus, but I never had a chance to make potions, so I happened to do it together this time. ”

"Thea, you and Severus ......"

"We are husband and wife, I love him, but he doesn't want anyone else to know, and he ...... Hate me. ”

"I'm sorry."

"It's nothing, can I get Madam Pomfrey to rip out my heart's flesh? …… I can't do it......"

"I'll take you."

"One more thing, Professor."

"What?"

"Don't tell anyone about this, okay? Including Severus. Cynthia looked at Dumbledore pleadingly.

After a long time, Dumbledore nodded and agreed to Cynthia's request.

Medical wing.

"What do you say? Let me rip out the flesh of Cynthia's heart?! It can't be, for whatever reason, I won't agree to it! It's too dangerous! After hearing their intentions, Madam Pomfrey decisively refused.

"Bobby! It's a request, and only you can do it! Dumbledore looked helplessly at Madam Pomfrey with his hands on his hips.

"Albus, it's not somewhere else, it's the heart! It's too dangerous, I won't agree to it! Madam Pomfrey spoke firmly.

"In that case, we'll have to do it ourselves, Professor." Cynthia said with some regret.

"Do it yourself? No! No! If you're not careful, Thea, you'll die! Madam Pomfrey raised her voice again.

"But madam, you don't want to help me, I can only do it myself."

"Do you have to rip it out?"

"Yes."

"Okay, okay, I promise you! But just this once! There will be no more in the future! Madam Pomfrey eventually relented.

"Albus, I need someone to give me a hand." Pomfrey looked helplessly at a serious-looking Dumbledore.

"I'll call Minerva here." Dumbledore waved his wand, and the phoenix-like Patronus flew out of the medical wing.

A moment later, Minerva McGonagall hurried in. "What's the matter, Albus?"

"Minerva, I need you to do Bobbi a little favor."

"Okay."

A minute later, McGonagall burst out again. "It's too dangerous! You can't do that, it's a child's play on Miss Black's life! ”

"Minerva, you have to trust Bobby. Just this once, okay? Dumbledore knew McGonagall wouldn't agree, so he wasn't surprised.

“…… Don't let anyone bother us! McGonagall stared into Dumbledore's eyes for a long time, but she compromised like Madam Pomfrey.

"With me, no one will bother you." Dumbledore raised his wand and cast several spells. An invisible barrier enveloped the entire medical wing, so that no one in Hogwarts could enter, and no sound could be heard.

It wasn't long before Cynthia's terrible screams came from within, and Dumbledore couldn't help but clench his hands when he heard it.

It took ten minutes for the screams to disappear into the medical wing. McGonagall walked out with four vials.

"Why four? Minerva, I remember we said it was three. Dumbledore was a little puzzled by the number of glass bottles.

“…… Miss Black, she wants to protect Lily......" McGonagall quickly put the glass bottle into Dumbledore's palm, "I have class in the afternoon, so I'll go first." ”

Dumbledore's eyes looked at the four vials in his hand with complicated eyes, and inside were four small pieces of flesh the size of mung beans, and the bright red blood stung his eyes. He didn't expect that in the end, Cynthia still wanted to save Lily's life.

He pushed the door open and walked inside.

Cynthia was unconscious, with a little blood on the placket of her clothes, and there was no trace of blood on her face.

"Bobby...... How is Thea? Dumbledore asked softly.

"She needs a break, Albus!" Madam Pomfrey glared at the old man beside her and said angrily.

"Take care of her, wait for her to wake up, and tell me." With that, Dumbledore left.

Cynthia was in a coma for three whole days. It took three days for her to slowly open her eyes.

"How does it feel?" Madam Pomfrey walked over as soon as she heard the movement.

“…… Water ......" Cynthia's voice was so hoarse that she could barely hear it.

Madam Pomfrey hurriedly brought her a glass of water, and it took a long time for Cynthia to regain a little refreshment.

At this moment, Dumbledore quietly walked in.
