Retirement from Hogwarts

"Ravenclaw's astral altar?! So Rowena hid him here." Dallion's eyes lit up as he looked at the altar that appeared in front of him. "How about you lend me the altar for two days after this adventure? I want to divine the whereabouts of a few books."

"What's the reward? If it's generous enough, it's not impossible." Jack looked at Dallion and said with a smile.

"Huh!" After hearing Jack's answer, Dallion turned his head to the side angrily.

"Matthew, just put your shield wherever you want."

Jack said, pointing to a cross-shaped depression in the center of the altar.

"Is that so?" Matthew asked Jack after putting the shield into the depression.

"Yes."

After Matthew put the shield into the groove, the star secret stone floor of the altar began to flow rapidly.In the end, only the circular part of the shield full of runes was left in front of everyone.

After the ground closed, a huge magic circle with a shield as its core enveloped the entire altar.As the altar continued to input energy into the magic array, a large number of magic runes and array structures were continuously copied from the magic array by the altar and combined into the air.

Finally, a tall hall made of energy appeared around everyone.The center of the hall is a small energy altar composed of the runes extracted from the shield and the magic circle that forms the hall.

"Ritual - Summoning of Heroic Spirits... How is this possible... Even if it is Chaldea in the future..." Matthew said while looking at the halo in the sky of the palace.

Seeing the ring appear above the hall, Jack couldn't help but smile with satisfaction.He stepped forward and placed a white battle flag with a black dragon emblem on the altar in the center of the hall.

"Declare, your body is under me, and my destiny is on your sword. If you follow the duty of a heroic spirit, follow this contract, and this world, then answer me! I swear here. I am the one who accomplishes all the good deeds in the world, I am the one who conveys all the evil in the world. Obey the ancient oath and emerge from the source of the world - the purifier of the world."

As Jack's spell fell, an ominous atmosphere began to fill the hall.The flag that was originally placed on the altar floated from the altar into the air at some point.Countless red magic powers like calamity flames are wrapped around the battle flag.

As more magic power from Jack's body poured into the magic circle, the red magic power around the battle flag had completely transformed into an ominous deep purple flame.

"Sin Yan...are all the students nowadays monsters?" Dallion twisted his body uneasily while looking at the purple flames in the air.At this time, the flames in the air seemed to hear what she said.The feeling of being targeted by a beast came to Dallion's heart.

The flag that was swimming in the flames of sin stopped in front of Dallion, as if he was examining something.Dallion looked at the malicious flag floating in front of him and opened his mouth to say something.But before she could say anything, it felt like she had stabbed the entire flag.

"Yeah~Yeah~"

Dallion looked at the incoming flag and couldn't help but screamed and squatted on the ground holding his head.

Just when the sin flames on the flag were about to touch Dallion, a golden light suddenly burst out from Jack's space bag and flew away the battle flag that was stabbing Dallion.

When the object in the golden light stopped in front of Dallion, everyone could clearly see the true face of the object in the golden light. It was a golden tulip battle flag exuding divine brilliance.

The previous Black Dragon Battle Flag seemed to be stimulated by something after the Tulip Battle Flag appeared, as if it were a real person.

He slowly and cautiously retreated to the altar.

After seeing the Black Dragon War Flag retreating to the altar, the Tulip War Flag rushed up to the altar as if it was unreasonable and began to compete with the Black War Flag for the magic power in the altar.As the competition intensified, the two battle flags began to chase each other in the air while absorbing the massive amount of magic power on the altar.

In the constant pursuit, the tulip war flag seemed to be stimulated by the cunning black dragon war flag, and the golden holy light that originally surrounded the war flag had been unknowingly dyed with an unsettling blood color.

Looking at the bloody holy light, everyone seemed to hear a disdainful sneer.The Black Dragon Battle Flag changed its previous behavior of avoiding everywhere and rushed towards the Tulip Battle Flag.

The moment the two battle flags collided, Hermione couldn't help but close her eyes.

"Master!"

Seeing Hermione standing there motionless, Matthew quickly rushed over, threw Hermione to the ground, and protected her with his body.

Dallion, who had triggered the battle of flags, had already hid behind the stone pillars of the palace and secretly looked out when the two flags started chasing each other.When she saw two flags carrying huge energy about to collide.Like the most astute hamster, she quickly retracted her head from outside the stone pillar, and squatted behind the stone pillar with her head in her arms.

"Ding"

A crisp metal clash replaced the explosion everyone imagined.When they opened their eyes and looked towards the altar, the two battle flags that had originally collided had disappeared.It was replaced by an energy cocoon with a huge halo.

As time passed by, the light cocoon on the altar began to stir continuously.As a powerful heartbeat sounded in the silent hall, the light cocoon disappeared in a burst of dazzling bloody holy light.

"Servant Avenger, Joan of Arc Darhk is here in compliance with the contract. I'm glad to see you again, my lord. This time, we finally don't have that stubborn woman to disturb us." A clear and hoarse voice came from the bloody The holy light came out.

"Damn, why did my voice become like this?"

"Servant Ruler, Joan of Arc Darhk came in compliance with the contract. It's great to see you again, my Lord God."

The same voice sounded again, but this time it seemed particularly clear and beautiful.

"Why are you such a stubborn woman in my body? Get out of here!"

"Don't you understand yet? Alt, this body is neither yours nor mine, but our common body. If I hadn't promised Lord God before the decisive battle that I would try to get along well with you when I meet you again, I would I won’t use this method to help you grasp the power of the crown.”

"With the power of a mere title, I don't need the help of a stubborn old woman like you..." Alter's voice suddenly stopped, followed by another groan.

"Now you understand. None of us can master this power alone, Alter."

"Tch, that's it for now. You must get out of here if you have the chance." Alter's angry voice came from the light.

As the light dissipated, a silver-haired and black-armored girl with resolute eyes appeared in front of everyone, holding a dark golden dragon-patterned war flag on a white background, with a red holy light wrapped around her body like a red lotus in the fire of karma.

"Savent Joan of Arc came here in compliance with the contract. It's a pleasure to see you again, Master."

The girl who appeared from the light said this in a voice that sounded like a duet with two different voices.
