"Sir?" Cynthia looked at the man on the throne suspiciously as everyone else left.

"Cynthia, good girl, come here." The man held out his hand to Cynthia.

"Sir, you left me to ......" Cynthia walked over to the man.

"Cynthia, I admire you, they can join me after graduation, and you, now!" The man stared at the girl with scarlet eyes, his words full of bewitchment.

"Sir, you, you mean, I, I can join your team now?!" Cynthia looked at the man excitedly when she heard this.

"That's right. The Dark Lord is merciful, and I'm willing to give you this opportunity! Voldemort looked at the girl's performance and nodded in satisfaction.

"Of course I do, sir!" Cynthia said excitedly.

"Bella!" The man shouted.

Bellatrix, who was waiting outside the door, pushed open the door and walked in. She walked quickly to the man, knelt down, and kissed the corner of the man's robe: "My Lord! Her eyes were full of admiration.

Cynthia looked at her cousin in surprise.

"Cynthia, like Bella, salute!" Voldemort looked at the girl's expression and spoke lightly.

Cynthia did not hesitate, knelt at the man's feet and kissed the corner of his robe: "My Lord! ”

"Hahahaha, that's good! Now, stretch out your left hand and let the great Dark Lord bestow you the reward you deserve! The man laughed.

Cynthia looked up and handed her left hand over.

"Roll up your sleeves!"

Hearing the man's command, Cynthia lifted the wide cuffs of her robe, revealing her smooth arms.

Voldemort pulled out his wand, pointed it at Cynthia's left arm, and said a spell she had never heard before.

As the incantation was pronounced, Cynthia felt the pain of her heart and the smell of burnt flesh coming from her arm.

"Ahh She tried to pull her left arm back, but she couldn't, and the man's cold left hand gripped her tightly.

"Alright, Cynthia. Take a look, what a charming logo! The man's lazy voice came.

Cynthia withdrew her still hot and painful left hand, only to see a black mark on her snow-white arm: a huge python sticking out of the mouth of a skeleton.

"Alright, girl, you've joined the Dark Lord, and you're going to do things for the Dark Lord!" Voldemort's voice became a little cold.

"I heard you've improved the amplification of the wand enhancement array?"

"Yes, master." Cynthia lowered her head, but her voice was a little hoarse.

"What's the biggest increase right now?"

"Fifty percent master, and besides, I can't increase this increase anymore."

"Good. Now, draw your improved formation on my wand! The man's voice was cheerful again, and he placed his wand in Cynthia's hand.

"Master, this ......"

"The Dark Lord's time is precious girl."

"Yes, master!"

Cynthia didn't hesitate any longer, she placed Voldemort's wand on her desk, bit her finger, and began to draw one intricate and mysterious rune after another.

Ten minutes passed, the girl's face became extremely pale, and the formation had been drawn successfully.

Voldemort picked up his wand and waved it, finding that it had more than doubled its power.

"Excellent! Cynthia, you make me very satisfied! You're still in school, so I won't let you go out, I'll give you a book, and your task is to learn all the formations above! The man handed Cynthia a thick old book.

"The Ancient Formation?!" Cynthia glanced at the cover of the book and said in surprise.

"Well, I'll tell you through Lucius if there's anything." The man stood up and left with Bellatrix.

"Thea? Are you alright, just ......" Lucius, Narcissa, and Regulus walked in worriedly, after all, they had just heard Cynthia's scream.

"I'm fine, don't worry! Lucius, the master has approved of me, he has taken me under his command! Cynthia said excitedly.

"So, the screaming just now was because of the mark?" Lucius looked at the girl in surprise.

"Yes!" Cynthia said, rolling up the sleeve of her left hand, and an ugly mark came into view.

"I really didn't expect that the master would mark you before you graduated." Lucius looked at the marker incredulously.

"So, I have to wait until I graduate, right?" Regulus's voice was a little muffled.

"It's just because my formation is better! Regulus, you are also very good! Cynthia patted her brother.

"You two just stay here! Uncle Oraine has promised me to let you stay overnight at Malfoy Manor. Now we can go and have lunch. Lucius opened the door to the study.

………………………………………

The next day, it was Lucius and Narcissa's wedding.

Cynthia packed up early and went to Narcissa's room.

"Thea, do you think I'm okay like this?" Narcissa ruffled her hair as she looked at herself in the mirror.

"It's beautiful already, Sicy! What you reveal from head to toe is nobility, elegance, and beauty! Cynthia looked at the big beauty in front of her.

"What should I do, I'm so nervous." Narcissa had been fidgeting all morning.

"It's all right, Sicy, when the time comes, just look at your dearest Luke!" Cynthia quipped.

"Have you packed up? The ceremony is about to begin! Regulus's voice came from outside the door.

"Alright, alright!" Cynthia quickly replied.

"Alright, Sicy, it's time for us to go out!" Cynthia helped Narcissa to her feet and helped her hold the hem of her long skirt.

The courtyard was already full, and Cynthia took her seat after handing Narcissa into the hands of her uncle, Signus Black.

Lucius was wearing a crisp white robe today, and his whole body shone with happiness. He looked at his wife and only felt that with this beautiful woman as his companion, his life was enough!

Cynthia couldn't help but reddened her eyes as she watched the two happily hug each other.

On the other side, Severus, his heart was full of bitterness, and he remembered the red-haired girl with a smile on her face.

After the wedding, their lives are back on the right track, but Cynthia has one more task.

Cynthia later found out that many of the formations in that book were legendary formations, but she didn't expect them to really exist.

What attracted her the most was an ancient protective formation from the mysterious East, which had a great deal of power to neutralize the attacks of the Requisition Spell. Moreover, it also has a nice name: Guardian of the Heart.
