HP in the name of Slytherin

Gringotts' treasury is based on a huge underground cave. The dragons raised by Gringotts live at the bottom, and there are tracks above, leading to different areas.

Some are just ordinary vaults, while others store important items. The vaults vary in size. Depending on the items stored, Gringotts will also set up different magic circles to provide additional protection for antiques, or to create a simulated ecological environment for treasures produced in the water. environment.

In order to protect the safety of this place, in addition to the giant dragon, from time to time there will be restraining potions rushing down like a waterfall. This is to test whether the person is disguised. In addition, there is an alarm device located some distance away. If you break in directly without tokens, keys or staff to guide you, the alarm device will make an earth-shattering sound, which can be heard by the dragon below and the staff above.

The first plan Catherine prepared was to wait until the magic potion washed down and "Voldemort" was discovered by the manager. Just like what she saw in Harry's memory, she would take advantage of the chaos to control the manager on duty, and then attack Voldemort... The success rate of this Not much, because "Voldemort" dared to transform into Bella and come to Gringotts. Catherine always felt that he would not be discovered so easily.

Sure enough, when three consecutive potions were washed down and Harry and others were exposed in his memory, Voldemort, who had transformed into Bella, just wiped his face with a handkerchief in disgust. The potion had no effect on him at all.

The car continued to go down, and Bella hid the gold cup in the Lestrange family's large vault. The vault was located at the bottom of the entire cave. Voldemort was not exposed all the way. A few minutes later, several people had arrived at Lestrange. In front of the Ranch family treasury.

The manager on duty opened a safety net with his own hands, and then said to Voldemort: "Miss Lestrange, please verify your identity, so as to prevent the things inside from being triggered to copy the magic."

Voldemort said "hmm", and Catherine stared at him as he walked to the door. She also verified with her hands. The door continued to make a "click" sound, and it turned out to be a complete success.

It seems that Voldemort has mastered the production of higher-end Polyjuice Potion. Not only does it maintain the original effect of Polyjuice Potion, but it also transforms into Bella's appearance. Even Gringotts' magic potion cannot restrain him, and it can also make him behave like a belle. Pull's identity is verified.

The moment the door opened and Voldemort was about to enter, Catherine knew she couldn't wait any longer and immediately took out her wand: "Collapse!"

While knocking out the manager on duty, she threw Helbo into the vault just as Voldemort discovered her.

The little basilisk instantly grew in size, sharing the memory read by Catherine, and with its keen perception of black magic, it immediately flew to the golden cup.

"Avada Kedavra! Split into pieces!" Voldemort chanted a curse crazily at Halbo.

The red, green and various colors of magic made people dizzy for a while, because when Voldemort attacked Herbo, Catherine also kept attacking Voldemort.

Her magic hit Voldemort's body, but it only caused ripples. It turned out that Voldemort had used super armor to protect himself at some point.

But Voldemort also made a mistake. He thought that Halbo would be delayed by him, or else he would resist the damage. Unexpectedly, the magic hit Halbo was also protected by super armor. At this time, it was too late for him to turn around and attack Catherine. Hear Haierbo shouting: [Bite! 】

With a snarl, its fangs bit into the gold cup, and suddenly a strong wind blew up in the vault, blowing countless gold, silver and precious stones all over the floor.

Voldemort could not feel the weakness of Voldemort in this world, but he could know through the dark magic flowing in the air that this Horcrux had also been destroyed.

"Avada Kedavra!" Voldemort suddenly attacked Catherine.

This spell is more powerful than ever, attacking not only Catherine, but also the unconscious goblin next to her.

As long as this goblin is killed inside Gringotts, Gringotts' alarm system will also be activated!

He thought that it was too late for Haierbo to return to defense at this time, and Catherine must have been the most relaxed under the success. She might even be distracted by protecting the goblin... just like when he opened the vault door and felt the Horcrux lying safely inside. .

Catherine broke his fantasy: "Magic is forbidden!"

Not only did she block Voldemort's attack, but she also took back Helbo when Voldemort attacked her.

"You!!!" Voldemort gritted his teeth.

Why can Catherine still use ancient magic when she comes to this world!

He can't even do that!

Of course Catherine would not tell him that after she woke up this time, she learned that ancient magic was different from modern magic, so she began to modify the ancient magic. The magic she just used looked the same as the ancient magic spell, but it was actually a new one with a new look. Magic, does not cause warning to the consciousness of the world.

Even if Voldemort was suspicious, he didn't have time to try it at this time, and he didn't dare to be distracted at this time. He simply drank a small bottle of potion to undo his transformation.

It was obviously very ridiculous to wear women's clothes with an ugly face, but the magic power surged around him, and all kinds of gold and silver on the ground trembled and melted in the blink of an eye. Catherine was forced to take a few steps back by the high temperature. At the same time, the entire Gringotts Cave sirens blare.

Roar--

The giant dragon on the ground roared and sprayed a stream of flames in this direction. In front of Catherine, the melted gold in her breath turned into small snakes and flew towards Catherine.

"Magic is forbidden! Drive out the enemy!" The golden snake fell down with her spell, and Haierbo behind her grew larger and swallowed the dragon flames in one gulp.

In addition to eating real food, the evolved Haierbo also likes to eat energy such as potions and magic. Dragon flame is of course also energy.

[Oooh, hot mouth! 】The basilisk whirred and jumped to the ground, pressing the Ukrainian iron belly that was already restrained by chains and unable to fly high to the ground.

Controlling the strength will not crush it to death, but it will prevent it from getting up and spitting fire.

"Avada Kedavra!"

Voldemort seemed to be trapped in the vault by Catherine. Faced with Catherine's killing curse, he could only dodge in panic. But compared to Catherine, who was still more worried, he had nothing to hide her tracks at this time, so she just dodged and cast her magic: "Powerful Explosion!"

He used the magic spell on the wall, and the vault, which was already fragile due to his magic, immediately exploded. He himself ran fast, and Catherine had to pull up the fainted manager next to her and get out of the way.

Explosions, roars of dragons, and sirens echoed in the cave, all of which made Catherine's ears ring. She could see a strong light flashing above, and it was Gringotts guards arriving quickly.

"My ancestor, if you stop me here, why don't you think about what your children will do?" Voldemort left these words before apparating away.
