[HP] Butterfly Effect

After getting Voldemort's order, Nagini went straight into the lake and left.The dark body merged with the lake water under the night, and after the initial spray subsided, only a ripple was left to move straight towards Hogwarts.

Snape was still kneeling on the ground, looking at Voldemort in front of him with empty eyes as if he had no soul.After the other party also disappeared in a puff of black smoke, his eyes suddenly trembled, and then turned into a kind of extreme hatred and anger, wishing to slash the person who stood here just now.

Adjani didn't notice the change in the other party, she just reached out and stroked Dumbledore's coffin a few times, and sighed hypocritically: "Okay, Severus, we have to sink him according to the master's order." It's not bad to think about it, he loves this school so much, let him sink with it, how romantic."

Saying this, she closed the lid of the coffin again, and pointed her wand at it.

Snape stood up and pointed his wand at Adjani without hesitation for a second: "Avadakedavra!"

The woman who was lazy and comfortable just now collapsed in the instant the green light flashed, her face was frozen with disbelief, panic, and deep fear.Snape took out the potion bottle in his pocket and poured it down to Dumbledore, who had no signs of life, watching him gradually recover from the cold death, and sat up from the coffin.

"Good evening, Severus." He shook his stiff hands because the body temperature hadn't returned to normal, caught a glimpse of the dead woman next to him, and probably understood what had just happened.

"When you wake up, get up and make room." Snape said to him impatiently.Then Ajani was stuffed into Dumbledore's empty coffin, and the coffin was slammed shut, and a spell blasted it into the water, splashing everywhere.He took out the Elder Wand from his sleeve and returned it to Dumbledore, speaking quickly and urgently: "Nagini has gone to find Potter, and he is going to find Field himself. I must go back immediately."

"That snake..." Dumbledore said thoughtfully, then grabbed Snape who was about to leave, and smiled at the other party's glaring, "Put on the sorting hat, there are Gryffindor's in it." Sword. I know Mr. Slytherin gave you the basilisk venom, and there has to be a sharp enough carrier to kill it."

Snape quickly withdrew his hand, disappeared in place, and walked to the principal's office, bypassing the frontal battlefield.The portraits inside cried out as soon as they saw him coming in: "That Potter boy ran out!! Wearing an invisibility cloak!"

This unplanned news made Snape grit his teeth with hatred, he knew that this boy was as reckless and brainless as his father, and no matter what the situation was, he had to rush out and participate in the disturbance before he was reconciled!If I knew it, I should have poured him a potion of living hell, tied him and Dumbledore and stuffed him into a coffin!

He found the Sorting Hat quickly, and drew out the Gryffindor sword amidst the chattering of the surrounding portraits.

The portraits immediately shut up.

Snape opened the glass tube containing the basilisk venom and poured all the venom inside.The sword body was eroded by the venom and emitted a slight white smoke, and then began to desperately absorb the venom as if it had self-awareness.

After doing all this, he put the sword into a pocket that he had cast the No Trace Stretch Curse on, turned around and strode away from the principal's office.

After a while, one of the portraits finally asked: "Isn't he the head of Slytherin? Why can he take out Gryffindor's sword? Or is he Albus who drank compound potion?"

……

She had tried every spell imaginable, but Nagini still followed them like a ghost.The last thing Aurora could think of before it pounced on it for the last time was to push Harry far away, slipping and falling to the ground as she was nearly exhausted.

The sharp gravel pierced into her skin, and Aurora felt the bloody flesh under her palm, felt the piercing pain, and saw Nagini's sharp fangs getting closer.

"Aurora!" Harry's scream almost changed its tune.

The Winged Demon swooped down from the sky and used its body to block the gap between the giant snake and its master. Aurora could almost hear the horrible sound of Nagini's bones cracking when he bit the blueberry jam, and the green blood scattered everywhere. splashed on her face.Blueberry Jam's jet-black eyes dimmed for an instant, and they didn't move anymore.

"No—!" Aurora uncontrollably attacked it with a spell, forcing Nagini to retreat for a short distance.It spat out the Winged Demon that had been shattered into a pool of sticky flesh in its mouth, opened its mouth and rushed towards her, and was hit by a curse from behind.

"Run, Aurora!" Tonks yelled, holding Harry behind him, "Quick—!"

Aurora tried her best to get up and run towards Tonks, fleeing along the corridor full of broken stones and glass.The drake glides through the air, spewing violent blue flames at Nagini, temporarily holding him back.While skillfully keeping a distance from the giant snake, preventing it from biting itself, it tried its best to cover its master from leaving.

They had been running for too long, and Aurora felt that the turbid air full of dust was constantly choking into her lungs, bringing a burning pain tormenting her, as if she was being stabbed by countless knives.

Why is it useless to this snake no matter what attack? !Why? !

Aurora thought desperately to keep herself awake, but it suddenly occurred to her that maybe it was because it was a horcrux, a living horcrux, like the locket and the gold cup, so no spells would work on it.

As soon as she thought of this, the dilapidated stone dome above her head collapsed, and smoke and dust rose up in an instant, as if swallowed by a chaotic nightmare.Tonks was hit in the shoulder by a heavy stone and fell to the ground, blood gradually covered his back.She curled up in pain, raised her wand with her good hand, and cast a petrifying spell at Nagini in despair.However, Nagini nimbly avoided her spell and bit her slender neck.

"Tonks—!" Aurora screamed, tears, sweat, and blood dripping from her jaw.Nagini let go of the immobile Tonks, turned around and bit her.

At that moment, countless pictures flashed before Aurora's eyes, but what was finally frozen was the image of Snape reaching out to brush her hair from her forehead.

"You'll be back, won't you?" she asked, imploringly.

"Yes." Snape replied.

But she was the one who couldn't come back.

She closed her eyes: "I'm sorry..."

"Go away!" Harry's hoarse and angry voice came suddenly.Aurora opened her eyes, and saw that the thin boy, who didn't know where the courage came from, actually hugged Nagini from behind, rolling on the ground with a man and a snake.

Nagini was loyal to Voldemort's orders not to kill Harry Potter, yet for some reason he seemed to have a protective spell that made him intolerable.When Harry rushed over desperately and threw it aside, a piercing pain was transmitted from Harry's blood-stained hands.The skin, which could not even be burned by the dragon flames, burned almost immediately when it touched Harry's blood, stirring like a hot steel needle piercing into the flesh.

The giant snake writhed on the ground in pain, blisters began to pop up everywhere touched by Harry's blood, and it tried desperately to throw Harry out, making a series of hissing noises.Harry also obviously found that it seemed to be very afraid of touching it. If they wanted to survive under the pursuit of this giant snake, then the only way was to hold it tightly.

As soon as this idea was formed, Harry's fear at the beginning was instantly replaced by anger and hatred. He tried his best to pinch Nagini's seven inches, and did not let go until the wound on his hand burst open again.

That was before he came to Hogwarts, a snake Harry met in the woods told him: "If any of our kind bullies you, you can pinch this part of it." Gray Snake raised its tail and pointed to a place below its head, "Actually, you shouldn't need it. You can talk to us, and we won't attack people like you. But you should remember, some of us Really bad temper."

The pain of extinction forced Nagini to struggle more and more, his tail flicked like a whip, and broke all the broken pillars in the surrounding corridors.Aurora crawled up to Tonks in embarrassment, using her body to block the falling stones for her.It's a pity that Harry is too young and doesn't have enough strength.Nagini quickly broke free from him, flinching away like a natural enemy, with huge snake eyes glaring at him viciously, with several hideous burns on his body.

"Come here! Come kill me!" Harry yelled at it, his heart was beating wildly, his whole body was shaking from blood loss and pain, his face was covered with dust, but his emerald green eyes shone amazingly, "You don't Dare, you cowards who dare not even touch me!"

"Harry?!" Aurora looked at him in disbelief, wondering what made Nagini so afraid of this 11-year-old boy.

The giant snake raised its head furiously, but at the moment it was about to pounce, it was completely pierced through the head by a cold sword.In the next second, its huge and terrifying body turned into a pile of black light ash, which was blown into the air and completely disappeared.

Snape withdrew his Gryffindor sword and put it aside with an ugly face, and stared at Harry with eyes almost as fierce as Nagini: "If you stay in the headmaster's office and don't move, you will die, won't you, Potter? ?!"

I don't know why, but the golden boy who had bravely rushed up to fight the giant snake with his bare hands to save his professor friend just now was stared at by Snape, and immediately froze halfway.

Compared with the head of Slytherin, Nagini is much more gentle and lovely.Harry Potter thought so.

However, he reacted in the next second and quickly jumped away: "You... didn't you kill Professor Dumbledore?!"

"Get out of the way!" Snape pushed him away irritably, too lazy to explain so much to an 11-year-old kid.Aurora turned her head to see him, tears welling up, ignoring the wounds on her hands, she grabbed Snape's hand, and cried heavily: "Save her... Tonks was bitten, no matter what Can't stop the bleeding, help her, Severus!"

Snape looked at the paper-white girl in Aurora's arms, and frowned: "Phoenix tears, call Phoenix over."

Aurora retrieved Hufflepuff's wand from among the ruins, and drew a bright arc of light towards the sky: "Fox—! Fawkes, Strawberry!"

Soon, Fox flew over with the newly reborn little Phoenix Strawberry on his back.

Holding a small bunch of strawberries in her arms, Aurora said tremblingly to the fiery phoenix: "Tears, I need your tears, please."

Fox floated to the girl's side and sprinkled crystal-clear tears on her wound. The blood turned back to the normal bright red color, but it was still slowly seeping out.

"This... what's going on..." Aurora rubbed Tonks' hands, trying to warm her up again, "why it still doesn't work?" It needs a lot of blood tonic and treatment." Snape skillfully treated Tonks' wound with a spell, "She has to go to St. Mungo's."

"I'll take her there, and Harry also needs treatment. I have coffee beans for us, and we'll be there soon." Aurora said quickly in a hoarse voice.

"And yourself!" Snape said through gritted teeth, his gaze scanned Aurora's whole body, and he could hardly see a good spot, full of wounds, blood scabs, dirt, broken skin, bruises, Covered layer upon layer.Some light blond hair was clotted with blood and turned reddish black.

"I'm fine, I'm really fine." She shook her head desperately, uncontrollable tears streaming down the blood on her face.She reached out to Harry: "Harry, come here, I'll take you to St. Mungo's."

As soon as the words fell, several Death Eaters who were hunted down by Aurors and members of the Order of the Phoenix stumbled towards here.The young dragon hovering in the air spewed scalding flames at them, almost setting them ablaze.

"You go!" Aurora grabbed Snape's hand and turned it into a hard push, "Don't let them see you helping me! You go!"

Harry struggled to process the scene before him, and it felt even scarier than having him face to face with Nagini's mouth.It was hard for him to understand what Snape was now. He had indeed killed Professor Dumbledore, but he saved them just now, and he and Aurora seemed to be...

Could it be that Aurora was cheated?

Harry thought in horror, instinctively feeling that this is impossible!

But is Snape a good guy?That's not like that either!

While he was struggling, Beverly and a Death Eater fought from the outside all the way into the corridor.Snape stood up, and without hesitation threw a death curse at the pseudo-colleague who was a little relieved to see him for a moment.Beverly looked back at him in surprise, at Aurora and the others, and then at Snape, probably understanding his position.

"Take them to St. Mungo's." Snape raised his chin slightly towards Beverly, and then, he looked down at Aurora, and said in a word, "I lied to the Dark Lord, tell him you Sent by McGonagall to find reinforcements that can help Hogwarts. He is looking for you everywhere now, you must stay in St. Mungo, and you are not allowed to go anywhere!"

After speaking, he helped Aurora up, and Beverly hurried over to hug the unconscious Tonks, feeling her body temperature was terribly low due to blood loss.

Considering that their physical condition could no longer withstand the phantom apparition, Aurora summoned the coffee bean thestral and the eagle horse Buckbeak, and two magical creatures, one black and one white, slowly flew into the sky with them.

The huge lifting force rolled up the dust on the ground and flew away one after another. In the middle of the night, the battlefield was dimly lit, and everything withered.Snape watched her gradually move away from his sight, rising towards the floating sky, and suddenly had a feeling that he would lose her forever.

For a moment, he wanted to call out the other party's name, but he quickly restrained the impulse that seemed superfluous under the current situation, turned around and disappeared in place.

With Aurora gone, all the magical creatures returned to her satchel except the green dragon and Fawkes who stayed at Hogwarts to fight with the others.She put the little phoenix in last, lowered her head and gently stroked the Thestral's bony neck, and whispered, "Let's go."

She saw Salazar when she passed the top of the castle tower, and the other party exchanged a look with her, and opened a hole in the protective cover.Thestrals charged up and rushed out, and the moment they penetrated the light layer, endless starlight and silver light poured down their heads, as if they had crossed the Milky Way, and the overwhelming dementors ushered in outside, they roared, crazily He rushed towards the unprotected people.

Aurora and Beverly raised their wands at the same time: "Call God to protect—!"

The silver black king snake and arctic vixen rushed forward with rings of bright silver light, fighting a bloody path surrounded by dementors.There is moonlight penetrating down from the sky above the head outside the encirclement, which is magical and beautiful.Harry sat on Buckbeak's back, clutching Beverly's robe tightly, lowered his head to avoid the gust of wind that hit his head and face, but saw that there were still dense dementors chasing them behind him.The temperature in the air was so impersonally cold that Harry couldn't help but began to shiver, feeling like he had fallen into the harsh winter.

At this time, the mask that originally covered Hogwarts suddenly became turbulent.It began to rotate and shrink, like a flower flowing backwards in time, the stretched petals converged again into a bud/bud, and then exploded suddenly, turning into a bright meteor in the entire night sky, flying around, dragging a long drag At the end, drive all those dementors away.

It was a sea of ​​light, and the silver meteors fell like a heavy rain with great noise, almost lighting up the entire night sky like day.Looking up at the silver meteor shower, which was more illusory and shocking than a dream, Harry lost all ability to speak.

A strange new patron saint quickly ran out from the source of the meteor shower, and joined the team of the black king snake and the arctic fox to drive away the surrounding dementors that hadn't had time to retreat.Aurora tilted her head and looked at the majestic and strange silver unicorn in confusion: "Whose patron saint is this?"

The unicorn seemed to have heard her words, and turned its head to stare at her with its pair of translucent long and narrow silver pupils.Aurora suddenly felt that the patron saint's eyes gave her a very familiar feeling, and couldn't help but startled: "Si... Severus?"

It briskly circled around her, and then led the black king snake and the arctic fox to run ahead by a long way.At the moment of breaking out of the encirclement, the unicorn finally collapsed into a ball of shining stardust due to exhaustion of magic power and disappeared.Thestrals led Aurora through those fine particles of light, and she reached out to catch those scattered light spots, as if clasping fingers with him.

At the same time, Dumbledore, who had been confirmed dead, actually returned to Hogwarts, which made all the defenders see hope.Some Death Eaters tried to escape here, but they were intercepted by the light shield covering the castle, and they couldn't leave at all.

"It's a trap!" one of them began to shout in panic. "We're trapped!"

After waving the Elder Wand to build a wall of fire to block the last retreat of the Death Eaters, Dumbledore looked at his defenders not far away with mixed surprises and smiled: "Save what you want to say for the final celebration." Come on, boys. We need to protect our school now."

"Kill them—!" Bellatrix snarled hysterically at him, the murderous look in her eyes became wild, and with a wave of her wand, the green light of the Killing Curse exploded and flashed.

Sirius confronted her with a spell without hesitation, and the two descendants of the Black family became sworn enemies on this battlefield.

"I've been waiting for this day for a long time." Sirius stared at her sullenly, the expressions on the faces of the two were somewhat similar, "I will kill you with my own hands to avenge Edmond."

"Hahahahaha." Bellatrix laughed shrilly, a frightening frenzy spreading across her bony face, as if she had heard something that pleased her in particular.In just a moment, she completely suppressed that smile again, the desire to kill distorted her face and covered her eyes, "Then wouldn't it be better for me to send you to accompany him?" As she said that, she suddenly put on a pitiful look again, and the dramatic expression change on her face could be completed in an instant, without any preparation, "I almost forgot, how miserable poor Edmond died."

"Nagini was very satisfied with that dinner." She said word by word, showing off Emond's last cruel end.

The uncontrollable anger drove Sirius to cast an Unforgivable Curse without thinking: "Crucio—!"

"Avada Kedavra--!"

……

The effect of the compound decoction was about to wear off. Peter Pedilou hurriedly climbed out of St. Mungo's hospital bed, covered his head with his coat and ran outside, bumping into many hurrying people along the way. therapist.

This bottle of compound decoction was stolen from the Ministry of Magic's drug management room when he escaped from Azkaban and attacked the Ministry of Magic with others. It contained an Aoi who had been killed by Death Eaters. Ro's hair.He recalled how he and the other Death Eaters fought against the Aurors and the Order of the Phoenix in Diagon Alley, and in the end he was severely injured by Sirius's spell and had to change back into a mouse form to escape.

He drank the potion of transfiguration and disguised himself as a wounded Auror.In order to cover up the truth, he even threw the dead Auror into the rat pile, and let those dirty and disgusting little things gnaw him beyond recognition.Then he was sent to St. Mungo's Hospital for treatment by other unsuspecting people as a wounded hero, and has been hiding until now.

This place may be the most dangerous but also the safest place, Sirius will definitely not find this place.he thought in horror.

When he was still young, Pediru knew that Sirius was the most difficult to mess with in their group of hijackers.Although he was a Gryffindor, he still had a lot of the viciousness and sternness that belonged to the Black family.He will take revenge on himself at all costs, Pedillo is sure.

And worst of all, Sirius recognized his own Animagus form instantly.

Thinking of this, Pedilu hid in a corner, opened the empty compound potion bottle, and tried to pour out a little more, but it was completely empty.

He threw the empty bottle away angrily, and came out from the corner in the form of an Animagus mouse again, but when he was about to escape, he saw a familiar person stumbled in from the front door.

It was the pale blond-haired natural animal trainer, disfigured and bruised.

He remembered the scene where her magical creatures had bitten off his ears and locked him in Azkaban, so he turned around and ran, running along the sewers and ditches to the wilderness far away from St. Mungo's.

Pediru, who had regained his human form, sat on the moss-covered stone and gasped for breath, but the surrounding air became cold and bone-chilling in an instant.He saw that the speed of the river in front of him gradually slowed down, and then it froze into ice, the flowers withered, and the leaves frosted.

This is the sign of the dementors coming.

Pedilu got up tremblingly, and sure enough, he saw those rotting creatures with no vitality approaching here, and Voldemort came with them.

"Master!" Pedilu knelt down with a plop, his cheeks almost touching the grass covered with cold hard hoarfrost, he could smell the faint scent of frozen grass.

"The dementor told me that the natural animal trainer of the Field family is around here, is that true?" Voldemort looked at him with lowered eyelids, which was a kind of indifference from a superior to a lowly creature, as if looking at an ant .

Pedilu nodded vigorously: "That's right, master. I saw her. She is in St. Mungo's Hospital and was injured."

"Very well," said Voldemort coldly, his eyes glowing red. "It is about time."

……

After giving Tonks the last bottle of blood tonic, Aurora was in the mood to treat her wounds.There were wounded everywhere outside, and the therapists were busy running around. She simply cut open the clothes by herself, and began to clean the wound and apply medicine.

The door opened, and a female healer's assistant walked in with several new bottles of potions, which were placed on a nearby table.Aurora looked up at the other party gratefully, "Thank you."

However, as soon as she finished speaking, she saw the female assistant in front of her raise her wand.

"He's here..." The female assistant was trembling all over, tears streaming down her face uncontrollably, "The person he's looking for is you, if you don't get out, all of us will die."

Aurora slowly put down the potion and scissors in her hand, stared straight at her, and asked softly: "Then do you think that if you hand me over, he will really let you go? Do you believe that murderer won't blink?" the Dark Lord?"

"I do not have choice……"

As soon as the female assistant finished speaking, there was a shrill scream and the sound of glass breaking downstairs, the sound of countless things falling to the ground, and the crackling sound of the confrontation between spells, getting closer and closer.

Aurora glanced at Tonks who was unconscious on the hospital bed and Harry who had just taken the palliative and fell into a deep sleep, and stood up without any hesitation: "I will lure him away, and you all go to the wounded as quickly as possible." move elsewhere."

As she spoke, she jumped over the female assistant and ran downstairs towards the source of the loudest voices.

Standing in the corridor on the second floor, across the hall filled with the mixed smell of various spilled cold potions, when she saw that familiar but completely unfamiliar figure, Aurora suddenly felt a strange calm in her heart.

It was as if she had been waiting for this day for a long time, and she had experienced it countless times.It was a relief of wading through the fog and murky waters, and finally ushering in the end of fate.

She stood there, looking at Voldemort in the form of Elias, without fear, panic, or surprise.The other party looked at her indifferent appearance, and narrowed his eyes playfully: "Hufflepuff's natural animal tamer, when you decided to join Dumbledore's Order of the Phoenix, did you think that you would be like this today? end?"

"It turns out that the person in my dream is you." Aurora said dreamily, and the wand slipped silently into the palm of her hand.The whole hall was full of dead bodies, and more people curled up in the corners, not daring to move, even crying desperately.

"Maybe." She raised her voice and replied, "However, what will happen to me, we will have to wait for you to catch up with me."

After finishing speaking, Aurora disappeared into an apparition, crossed Voldemort to the gate of the hospital, and ran all the way along the desolate outskirts.

"Death struggle." Voldemort looked at her back grimly.

Breaking into the encirclement of the forest, Aurora was instantly submerged in a muddy and wet silence.The sky overhead has begun to show signs of dawn, and the oppressive darkness is gradually fading away, turning into a deep and melancholy ink blue.The fragile light of the far east is spreading from the struggling growth bit by bit, being sifted down through layers of tree shadows and falling into sight, floating above the head like a pale and vain ghost.

Before dawn, the forest was thick with mist, and Aurora ran through it, feeling like she was about to drown.

Then she stopped in a clearing and looked at the familiar little ugly man in front of her, Peter Pedilou.

Pediru's small eyes were fixed on her, with fear on his face: "You can't win against the Dark Lord, and neither can anyone. Your resistance will only bring more futile defeat and death." "Really. "Aurora raised her wand, and the arc of light spread out instantly, and a beautiful dragon chant spread across the sky instantly.Pediru's face turned pale immediately, like a dead body from which all the blood had been drained.

"Total petrification!" Aurora swiped his wand downward, the golden magic beam fought against the death curse fired by Pedilu for a while, and then backlashed back with an absolute advantage, petrifying him in place.

"Burn him."

As soon as Aurora finished speaking, the silver-blue young dragon hovered in the air, and opened its mouth to spit out blue flames towards Pediru.After a crackling sound, the man who was still stiff just now turned into a pile of ashes in the flames.

The pitch-black mist spread murderously from behind, and Aurora heard a hoarse whisper that belonged to the Parseltongue entering her ears.Immediately afterwards, countless poisonous snakes with bright patterns came out from the trees, from the holes in the ground, and from the grass.They surrounded them in groups, the small ones might be as thick as a wand, and the big ones might be as thick as an adult's arm.In less than a few minutes, Aurora was sealed in place by these poisonous snakes.

Realizing that its master was being threatened, the fire dragon was furious. It hovered nimbly and gracefully in the sky, and lit all the surrounding forest trees with powerful dragon flames.Bright blue flames jumped around, forcing those poisonous snakes back out of the fire circle, and isolated a piece of pure land for Aurora.

With a sigh, Aurora turned her head and saw Elias's face beyond the firelight, but the expression was Voldemort's, cold, vicious, arrogant and morbidly crazy.

"It's quite emotional, isn't it? It seems that Hufflepuff has never learned to distinguish the proper position. Your ancestors were like this 1000 years ago, and you will be like this after 1000 years." Voldemort's fingers lightly along the wand Sliding lightly, the scarlet eyes reflected the bright blue flames, intertwined with a strange purple, making him look like a human being at all, "It seems that you, as a descendant, are the same as other students in your academy, the same madness."

"How do you know?" Aurora tilted her head to pretend to be surprised, and then realized, "Snape told you."

"You don't look surprised at all."

"He killed Professor Dumbledore in front of me. I should not be surprised by that."

Voldemort laughed, there was no warmth in the laughter, it was more like mocking something coldly.

"It seems that you are ready. Surrender to my coexistence, or die. This is the fate that every natural animal trainer cannot escape, and you are the same."

"Your fate is like this, you are destined to perish here!"
