The dragon roared and spewed flames, its formidable body rampage through the narrow tunnel.

With a loud bang, the underground tunnels of Gringotts were rapidly collapsing, large rocks fell, and the entire space shook violently.

Evan blasted with magic, and the dragon spewed blazing flames again and again, and together they exploded and melted the hard rock barrier in front of them.

Along the way, the dragon tore through the path with its claws, heading deeper into the tunnel.

It tore open a vault from the side, and I don't know which wizard family's vault had been destroyed like this, and the treasures of gold, silver, jewelry, and magical objects treasured for centuries were scattered all over the ground, and the dragon's massive body rumbled through the fine gold ornaments, throwing the crushed gold and silver jewels everywhere.

A piece of exquisite jewelry turned into a gold cake with no beauty at all in an instant under the trampling of the dragon.

Soon, they vandalized all the way to the upper vault area.

Evan saw that outside the Lestrange family's vault, the gold and silver jewels continued to swell and increase, and they quickly squeezed all the space.

He swung his wand forward, and the dragon rushed forward.

The dragon took a deep breath and a flameburst of flames, and the gold, silver, and jewels that had caused trouble for Evan and them quickly vanished.

But under the effect of magic, the whole space became even hotter, and the temperature skyrocketed, as if it was about to melt the air.

Continuing on, the tunnel leading deeper into Gringotts, the heat and dust causing Aven to squint.

He endured the roar of the falling rocks and the dragon, clinging to the dragon's back to prevent it from being shaken off, and while he flicked his wand and used the explosion charm to help the dragon open the way, Hermione, Harry, and Elaine also helped, constantly using the Splitting Charm and Digging Charm on the rocks, and the group sped forward.

The dragon stepped out and squeezed through the metal door, Aven, Harry, Hermione, and Elaine still clutching its back.

They followed the dragon through the narrow barrier into the wider cavern, where they saw a network of rusty, intricate cart tracks trussed in the air, which stretched out of the cracks in the rock wall and down into the cavern, sometimes intertwined and quickly separated, with no end in sight.

The dragon finally found space to spread its wings, and just now the wings in the tunnel were stirred up by the rock wall, causing a hurricane.

Aven rode the dragon all the way down, towards the depths of the earth.

Nothing could stop them, and the rusty tracks were fragile compared to the hard rock walls.

Under the impact of the dragon, they were quickly crushed, turning into rags and falling down.

Without railroad tracks, the elves would not have been able to come over anytime soon, preventing Evan and the others from entering the vault in a deeper area.

These were Gringotts' tightest defenses, but now they stopped the guards.

The Gringotts goblins who designed and built it probably never dreamed that someone would break into an underground vault in this way.

For thousands of years, Aven, Harry, Hermione, and Elaine were the only intruders to ride dragons into the area.

Either way, they will leave their names in the history of magic, and this is enough to be recorded.

The most rampant, the most arrogant, the craziest Gringotts thieves, they broke into Gringotts today, in such an amazing way.

Soon, a bright red streak appeared below, the color of magma deep in the crust.

The temperature continues to rise and continue downward, and the red magma deep in the earth's crust becomes more and more evident in this huge bottomless crater.

The round, crimson pool of magma below is like a gateway to the depths of hell.

Roar!!!

As if stimulated by the magma, the dragon once again erupted in flames.

It was responded to by billowing heat waves and leaping sputters of magma, with what appeared to be countless dragons spewing fire upwards below.

Molten lava, dragons, flames, all of this fused together to form a rare fantasy landscape, incomparably shocking.

In the loud noise, it seems that some monster is waking up, feel the boundless fury, let the flames purify everything!

This is a world of flames, and even the hard rock has been scorched and turned red, and some of them have even begun to crystallize.

Although the temperature was already unbearable, Evan still controlled the dragon to continue downward.

Soon, they found the islands in the magma pool, and the islands were filled with ancient stone sculptures, all of which were in various shapes, all of which were the emblems of the oldest pure-blood wizard families, the last marks of these illustrious families from thousands of years ago, and the entrance to the family vault.

"What's the matter with these vaults?" Elaine shouted, staring in shock at the islands, stone carvings, and vaults in the molten lava.

"They were all early coffers built at the time of Gringotts' founding, and there were a hundred of them, owned by the most powerful wizards in the world at the time, or the most powerful pure-blood wizard families. "But because it's so old, the wizarding families here are basically gone, and all the treasures they left behind are left here, becoming part of Gringotts." In fact, in a sense, this is the real Gringotts. Ah, Vault One is there, and we land. ”

Evan controls the dragon to descend on the island in the center of all the islands, and in front of them, many emerald statues are emitting a soft green light, and they combine to form the familiar capital S, the emblem of the Slytherin family.

Above the letter S is the number "One", indicating that this vault was the first vault to be built in Gringotts.

In a sense, Gringotts was created because of this vault. At that time, elves were enslaved by wizards like house-elves, and were a subordinate race of wizards, and Salazar Slytherin ordered his elven servants to build this vault in the deepest part of London's underground to preserve his treasures.

This is also the origin of Gringotts, but later due to rebellion and rebellion, the elves gained their independence and became a magical race independent of wizards.

Gringotts gained its independence at that time, and the greedy nature of the elves allowed them to build on Gringotts. Over the millennia, Gringotts has become an essential part of the wizarding world, the most trusted place for wizards to keep their wealth.

As for the original secret, it has long been lost in the long river of history and forgotten by the world.

If Aven's reasoning is correct, then Gringotts One Vault would be the place where the key to Salazar Slytherin's secret treasure is kept.
