Slytherin's salvation is nothingness

The huge waves surrounding the castle were suddenly broken by a magical force, and the black fire continued to devour the tide. A large hole appeared in the defense of the castle's main gate, and the Death Eaters looked behind them in surprise. Cyrus walked in front, and Lucius pointed his wand at Snape from behind and pushed him forward. Following behind them was the army of staggering Inferi.

"Owner!"

Facing the excited and surprised eyes, Cyrus stretched out his hand and shook it. The Death Eaters in front of him trembled, their souls quickly burned out, and they fell down with no life in their eyes. Cyrus stepped directly over the fallen bodies and said lightly, "Useless trash."

The other Death Eaters had no time to escape, and fell to the ground one by one, unable to think about why their master wanted to kill them. The black Fiendfyre moved along both sides of the road, and the flames enveloped the entire Hogwarts. It attacked everyone regardless of friend or foe. Fortunately, everyone who took the Felixir Potion avoided the sudden appearance of the Fiendfyre. But they were still locked in the castle and unable to move.

Harry and the others who arrived just happened to witness Cyrus killing a Death Eater. "What happened?! She suddenly became a good person again?"

Harry shook his head solemnly at the Inferi behind him, "I think... compared to the Inferi who are not afraid of death, those Death Eaters are nothing."

Cyrus had already walked to the front of the castle, and was looking at Salazar who was standing in front of him. The tide swept over, and he resisted the invasion of the black fire. The magic power full of dark breath surrounded Cyrus's body, and the roar of Voldemort kept ringing in her mind. The two souls entangled and tore each other apart, killing them, killing everyone!

Cyrus's whole body was shaking, and he couldn't stop laughing crazily. The sound seemed to be amplified dozens of times, filling every corridor of Hogwarts. His eyes were stained with blood, and there was an undisguised bloodlust raging in his depths. Everyone trembled, and fear far greater than that brought by facing Voldemort swept through their bodies.

A golden ball of light appeared in her hand. It soared into the air, gradually grew larger, and the light kept flickering. Salazar's face darkened the moment he saw the ball of light. He looked at the girl in front of him, lowered his eyes and sighed. He shouted to McGonagall and others behind him, "We must stop her. The magic contained in it can destroy the entire Hogwarts dozens of times! Everyone, form a circle!"

Hermione dragged Harry down the stairs, she was already crying, "Why does it have to be like this..."

"What the hell is going on?! Why is there only Cyrus? Where is Voldemort?"

"Probably... Voldemort is gone. Her magic power has increased dramatically but is unstable. She must have merged with Voldemort through the connection of the Horcruxes. Voldemort cannot continue to fulfill the Dark Lord's mission in the hands of Grindelwald and his men, so she has to do it. The invasion of European countries and her own country, the killing of Dumbledore, and her terrifying strength, until now, she has become the most threatening Dark Lord in history. She has also completely cut off her own retreat and left us no chance."

Ron's brain was in a state of confusion. Between being afraid of death and fighting bravely, he chose to complain, "Okay, okay, so our hope of winning has become even slimmer. Is she just showing off her strength in front of everyone or trying to belittle Voldemort?"

"Maybe waiting for a hero to appear."

The huge ball of light continued to expand, and was almost close to the castle in front of him. Snape looked at the people who were still guarding the castle. Professor McGonagall's hands were shaking, and her eyes were looking up at the ball of light in the sky. Flitwick, Sprout, and Slughorn stood beside her. Flitwick suddenly said, "Even if it is my last words, I was relieved when I knew that it was not you, Minerva, who became the headmaster. After all... sometimes you are too strict."

"Haha, really? Better than Severus. I didn't expect you to be so harsh on a teacher like me." Slughorn drank the bottle in front of his chest and threw it aside.

"Didn't Severus help us in the end, with those potions and medicines?" Sprout touched the small shovel in his pocket regretfully and clenched his wand.

Click, click, click.

Countless footsteps sounded from behind, with the members of the Order of the Phoenix walking in first, followed by the remaining students from Gryffindor, Ravenclaw, and Hufflepuff. Finally, it was Draco.

They lined up in front of the castle. Mag laughed helplessly and raised her wand first. "Let's protect our home together!"

Wands were inserted into the ground, forming a barrier in front of Cyrus. The golden cracks in the ground stopped behind Cyrus, and Snape looked back. Grindelwald and others were breaking through the Inferi's blockade to get here, but time seemed to be running out.

"That ball of light will destroy everything." Lucius' voice came from beside him. He couldn't hold the wand in his hand and was shaking with fear. Then he cried out in pain. Snape seized the opportunity and pushed Lucius away. The moment the binding spell disappeared from Snape, he rushed out.

"Professor Snape, take it!" Draco, who had secretly come behind the two of them, snatched the wand from Lucius and threw it at Snape.

The rough texture of the wand passed through his palm, and Snape felt the magic power in his body rapidly expand. Without thinking too much, Snape threw out a series of air blades to first break the road blocked by the Inferi behind. When he pointed at Cyrus in the center again, he was stunned. She was smiling at him...

"So, can this slow-witted hero slay the dragon?"

The fierce fire surrounding the castle disappeared, and Cyrus stopped sending spells to the light ball. A figure of the Grim Reaper holding a scythe appeared behind him. Fire snakes, dragons, and tides appeared under the huge light ball. Snape took out a bottle of potion from his chest and drank it. This was the only potion that Cyrus had not discovered. After drinking the potion, his magic power surged again, and the ancient wand in his hand glowed faintly.

"Who knows? Besides, I just want to kill you."

The black fog hid its body and kept changing its position to launch attacks. The Fiendfyre could not attack high in the open field. The fire snakes and dragons had a single attack method, and the tide would change its direction regularly. Everything was too familiar, not only the battle in the observatory, Snape was familiar with all of Cyrus's attack methods, and even fought back effectively.

Seeing Snape fighting back and forth with Cyrus in the field, Harry couldn't help but be surprised, "Snape, is he so strong..."

"He's not weak to begin with... and he's holding the Elder Wand, so he can cast powerful spells easily. Focus, Harry! Grindelwald and the others will be here soon, don't miss the chance to cast a spell."

There was a sound from the bag on her waist, and Hermione looked back and saw a dark dog face. The transformed Sirius picked up a glass bottle from Hermione's bag.

"Sirius, what are you doing?! We should try our best to stop the explosion of the light ball now." Hermione tried to grab the big black dog behind her, but the dog dodged flexibly. Sirius, who had recovered, held the bottle tightly and threw it into the smoke in the field.

"If she was still Cyrus, she wouldn't have caused the explosion. She must be stopped before Snape stops her." Sirius didn't dare to guarantee it, but his premonition became stronger and stronger. Cyrus would definitely be stopped by Snape, and then neither the British Ministry of Magic nor other countries would let her go.

A ball of silver light suddenly appeared in the black fog, followed by intermittent sounds and images.

{A girl in a Slytherin school robe walked through the hall, her temperament was indifferent and elegant, and her whole body was glowing. "Hello, I am Cyrus Slytherin."}

{"Miss, it seems a bit bad to enjoy Halloween night in the bathroom, isn't it?" The girl's eyes were soft and she handed over the ring with a smile.}

{"Ms. Granger, could you please wait a moment before worrying about Potter over there? I think I need to deal with the pierced arm more."}

{"This year's House Cup winner is - Slytherin!"}

{"I will be your teaching assistant for the alchemy class. Please give me your guidance."}

{"Ask me questions? Of course."}

{“Me? I’m trying to find a reason.”}

{"It was a great Quidditch game, sorry for freaking out your keeper."}

{“Who would want to hide if they can live openly?”}

{“What is love?”}

{“Mr. Big Black Dog, please stop rubbing my floor with your fur, or I’ll have to ask Kul and the others to clean it up again.”}

{"Remus is funny when he's drunk, but not nearly as funny as you are. Mister who fell into the mud?"}

{"Yeah, we're friends."}

{“You must live well.”}

{"Go back, Sirius. Thank you."}

{"Professor Slytherin, Professor Slytherin, Professor Slytherin!"}

Scenes of Cyrus's time with them appeared before his eyes, and the last scene was Cyrus' happy smile surrounded by all the students. In contrast, he had a bitter smile standing in the black fog.

"You don't understand. I never needed to be saved, and neither did he. Victory is earned by oneself."

I felt the hurricane coming from behind me, getting closer and closer, until a warm feeling surged from my waist. I heard Grindelwald's scolding from behind me, "The Dark Lord is not like you!"

The missing barrier was filled by Vita and others, and everyone pointed their wands downwards, and all the spells came to an end!

The flickering ball of light gradually dimmed, and all spells failed. Snape landed in front of Cyrus, "It's over."

Looking ahead, there are faces looking at this side. Professor Sprout is scared again. Maybe he can no longer sneak into the botanical garden to steal herbs. Professor Flitwick's cake can't be eaten either. Ah...Witt and Cool, Salazar is really meddling. Gellert must be very angry. Maybe I am really not cut out to be the Dark Lord. Kate should be able to handle the rest. She is a very good assistant. Members of the Order of the Phoenix... The twins' alchemy is better and they don't seem to need my guidance anymore. Professor Moody's leg cannot be healed, but it's better than falling off the broom. What is Remus' child's name? I don't think I have asked it yet. Sirius didn't rush over, that's great. You are still alive, that's great. And one last thing.

She covered the bleeding wound on her waist, drew a sword from her back, and all the magic power in her body rushed to the light ball above. Even Salazar was very surprised that she could resist everyone's spell with her own magic power.

"Gryffindor's sword is rare, appearing in the hands of a Slytherin. You know you can't kill me with a spell." The scarlet eyes flickered, as if endless pain spread from them. The light ball above could explode at any time. Cyrus walked towards Snape with the sword in hand, and the slashing action was easily blocked by him.

Snape held her wrist tightly, an indescribable emotion spreading in his heart, as if something buried deep in his heart was being unleashed. He had to kill her, he had to.

"kill me."

His eyes fell on the deep and light blue, and a pain rolled from the bottom of his heart, rushing to his throat. The wand in Snape's hand became extremely heavy, and he realized that it was the Elder Wand. He also found that the owner of the Elder Wand had always been him, not since he accidentally killed Dumbledore, but a night long ago... the night when he traumatized the girl's eyes and knocked the wand out of her hand. So she had made up her mind since then.

"What is the ultimate victory for you?"

Cyrus paused for about half a second, looking at him with a sad and lingering look. When he spoke, his voice revealed boundless sadness and sorrow.

She quickly clenched her palm, grabbed Snape's hand and stabbed the tip of the sword into his chest, "It's you, everyone's hero. My hero." With her other hand stretched out to the sky, she smiled with relief.

"Resurrect yourself with your own hands, sir. Please, truly, live."

The two souls entangled in Cyrus' body fell into the ball of light. The ball of light, which could no longer contain any magic power, expanded again, and golden light visible to the naked eye overflowed. A loud noise came from the sky, and wisps of golden light scattered, rushing to the corpse behind when everyone was too busy to escape. Guangxu sank into the corpse of the Yin, and the magic power containing a thousand years of life force moisturized the dry skin of the corpse, and gradually grew smooth skin again. The people who woke up one by one looked around in confusion. They, weren't they already dead... And the last ray of Guangxu flew away and entered the Screaming Shack.

A pair of big hands pulled up the lady next to him, and along with the sweet smell of candy, "Bobby, welcome back."

"Albus? What's going on... Why are there so many people in Hogwarts?" Madam Pomfrey was pulled up by Dumbledore and looked at the people surrounding the castle, her eyes fixed on one place. She covered her mouth tightly to prevent the sound of crying from spilling out, and squatted on the ground in pain.

The dawn of victory illuminated the earth, and the cry of the phoenix resounded throughout Hogwarts again. A black figure stood in the center of everyone, hugging the girl in front of him tightly. He kept calling her name, but there was no response.

Dumbledore looked at Grindelwald who was silent in front of him. He shook his head slightly. "The one she loved was imprisoned in the depths of hell, and she gave everything to make a deal with the god of death. She did what no one could do, breaking the rules of the world and saving lives."

The non-existent heir awakens with disaster, thousands of lives are buried, the power of the soul transcends death, the world no longer needs a savior, and everything she has returns to darkness.
