"Silent spell? When did you become so strong?"

Alice asked in surprise.

John threw the body of the goblin with the nose ring out of the car, then sat in front and started driving.

His strength has indeed been greatly enhanced.

This is related to the fact that he started drinking high-level magic potions as water a long time ago.

But the main reason is still due to the dementors' siege on him when he left Hogwarts.

Dementors, creatures that are almost entirely composed of negative energy, can provide much more magic power than advanced potions can provide!

In the past, because he had to resist the erosion of negative emotions, John was relatively restrained when devouring dementors.

But that day, John completely opened his heart and used another more extreme method to permanently solve the problem of negative emotion erosion.

This directly caused him to swallow hundreds of dementors almost at once!

Such a huge influx of magic power almost exploded all three magic pools in his body.

And for several days after that, John could no longer absorb any external magic power through his 'chewing' ability, and it was not until later that he slowly recovered.

However, compared with this sequelae, the contribution of the Dementors also allowed John's magical talent to nearly double once again.

Nowadays, his magic power is at a level similar to that of top professor-level wizards like McGonagall, both in terms of quality and quantity.

Not only that, John also received a terrifying increase in the smoothness of his spell casting and his control over magic power, so much so that he could even master techniques like silent spells without a teacher.

At this moment, John's combat effectiveness is comparable to that of the most elite Aurors.

Even against powerful men like Snape and Flitwick who have extremely rich practical experience, John is confident that he will not fail!

And this also gave John some different thoughts about the dementors.

He has already thought about it.

If there is a chance in the future, he will definitely go to Azkaban to repay the kindness of the dementors.

As for the question raised by Alice...

"It will come naturally...perhaps it's because of talent."

John replied calmly.

"Hahaha--"

Alice was amused.

She moved closer to her mouth and said with a chuckle:

"Well, this genius wizard, the nose ring just made it very clear. Without the goblin, no vault door can be opened. If you want to rob the vault..."

John interrupted:

"I'm not interested in the treasure here."

"Yes, yes, everyone knows that you, John Shafiq, are a rich man." Alice said, "But if you don't want to steal the goblins' most cherished treasure, how are you going to retaliate against them?"

"You'll find out soon enough."

John spoke and controlled the car to slowly stop at the deepest part of the underground vault.

The two got out of the car and walked forward along the corridor.

Along the way, Alice was still complaining about John's betrayal.

After all, the two of them are now teammates on the same front!

However, just after turning a corner, Alice suddenly covered her mouth.

A huge dragon is tied to the ground in front, guarding the four or five deepest vaults.

Due to being confined underground for too long, the scales on the dragon's body have become pale and loose. Its eyes are cloudy pink, and its two hind legs are wearing heavy shackles. The thick chains on them are connected to the stone ground deeply.

The huge pile inside.

Its giant, spiked wings are folded at its sides, and if unfolded, it would fill the entire basement.

The dragon turned its ugly head towards them, let out a roar that made rocks tremble, opened its mouth and spit out a stream of fire.

"boom--"

John summoned a translucent magic shield to block the flames.

Alice was hiding behind John, looking at the fire dragon curiously:

"There is really a dragon underground in Gringotts! And from the looks of it, it must have been imprisoned for many years... Oh my god! I thought the goblins were bragging!"

John ignored Alice.

Holding the wand, he withstood the fire dragon's constant attacks and came straight to the fire dragon. While the fire dragon was roaring, he poured a large bucket of crimson potion into the fire dragon's mouth.

Alice asked:

"What did you feed it?"

"Do you still remember the crazy Iron Belly Dragon of the Uzbek Kingdom during the second event of the Triwizard Tournament?" John said, pouring another bucket of potion, "The composition and effect of this potion are the same as the Iron Belly Dragon of the Uzbek Kingdom.

The dragon drank almost as much."

Alice's eyes lit up and she said:

"Then are you going to stick a thick silver needle into the back of its head to make sure it goes crazy?"

"It's not necessary. After being imprisoned for so many years, this fire dragon has long gone crazy. By the way, bring this with you."

While talking, John handed Alice a gas mask.

"What's this?"

Alice asked, putting it on.

"You should know from the appearance that it is used to prevent inhalation of poisonous gas. Don't ask such stupid questions next time, if you still want to follow me."

"I know, of course I know! I just want to ask, why do you want me to wear this?"

John did not continue to answer Alice, but took out two more barrels of gray-purple potion and slowly poured them on the ground of the entire underground space.

Finally, John used the [Disillusionment Curse] on himself and Alice, hid in a corner, waved his wand, and chopped off the huge iron chain binding the fire dragon.

"Crash-"

The chain fell to the ground, making a series of loud noises.

After a second, the fire dragon finally realized that it was free.

Amidst the deafening roar, the fire dragon stood up, spread its wings, and rose into the air.

However, the underground space is too narrow for the huge fire dragon.

It can't fly out at all.

"boom--"

The fire dragon opened its mouth and spit out flames.

A violent explosion sounded.

The roof of the cave was directly blown into pieces.

The huge impact shook the entire underground cave.

The main body of Gringotts on the ground naturally felt this shaking.

A large number of gold coins and gems placed on the table fell to the ground.

The goblins picked it up in a panic.

The goblin sitting behind the tallest counter opened his eyes wide and roared:

"The fire dragon is out of trouble! All goblins! Go to the underground vault and gather! Do you hear me clearly? I'm talking about all goblins! Only goblins are allowed to go there, wizards are not allowed to go!"

After saying this, a large number of goblins began to gather and rush toward the underground vault.

When they saw clearly that the fire dragon in the underground vault was pulling at the roof of the cave and spitting flames in an attempt to escape from the cave, all the goblins became angry.

"This despicable lizard dares to destroy the fairies' property!"

The leader of the goblin roared, "Quick! Subdue it! Lock it up again! This time I will starve it for at least a month!"

Hearing this, the goblins took out some kind of silver object that looked like a musical instrument.

As they shook the thing, a series of crisp sounds continued to come out.

Hearing this sound, the huge fire dragon began to scream crazily, as if it had been subjected to some kind of inhumane torture.

Seeing this, the goblins' faces showed a look of pride.

They had raised this fire dragon underground since it was a dragon egg.

When it was just hatched, the goblins began to torture it with knives and axes.

And every time you attack it, it will sound the unique musical instrument simultaneously.
