Aven, Harry, Hermione, Elaine, and the old elf quickly climbed the spiraling staircase inside the tunnel, where the cart stopped.

The dragon's head could be seen just outside the protruding platform not far away, and it looked extremely violent, its large, dangerous head shaking violently.

The dragon was roaring, spewing flames.

At this moment, the entire cave suddenly began to tremble slightly, making a strange noise.

"What's that sound?" Hermione paused.

"It's the siren, they've spotted us!" said Aven, his heart sinking.

There was so much protective magic in the Lestrange family's vault, and the next level of the tunnel, the ever-increasing amount of gold, silver, and jewels were rapidly spreading from the vault, and it would be strange if the goblins of Gringotts didn't notice anyone breaking in.

In a matter of minutes, hundreds of goblins and heavily armed wizards would rush down.

"We have to get out of here, there's no time to go to vault number one below. ”

Indeed, thinking of the intricate tracks in front of Vault One, Aven wondered if they would have a chance to come up after they got on the cart.

In the current situation, it is really unwise not to run away, and then go to Vault No. 1.

They have already obtained the gold cup, the main purpose of this trip to Gringotts has been achieved, there is no need to go to the No. 1 vault to risk, but just leave, Evan is a little unwilling, this is a rare opportunity to break into Gringotts, and even if you escape, how to run is a big problem.

Returning along the way, waiting for them is also the Gringotts Tunnel Labyrinth and the guards with all the defenses open.

Just going back like this, it's like looking for death!

The fidgeted dragon began to roar and spew flames again as the cavern shook.

At this moment, an inspiration, or rather a crazy idea, came to Aven's mind, and he could control the dragon.

That's right, control the dragon!

The Imperius Curse can control living beings, and while few wizards have managed to control magical creatures with such powerful magical powers as dragons, it is theoretically possible, and Aven knows that there are wizards in China who can control dragons.

They use trained dragons to guard magic schools and other important places, and have come up with many unique and effective methods of control.

Evan had read books such as Chinese shamans burning the powder of tea leaves to make dragons happy, feeding dragons chili peppers to make them breath stronger, and whipping them with leather whips to massage them to enhance their feelings.

Although Evan was not aware of these control methods, he could still do it directly with the Imperius Charm.

And his strength is the magic that far surpasses that of ordinary wizards, strong enough to control the magic of dragons.

Thinking of this, he pointed his wand at the dragon and shouted, "Out of body!"

Evan increased the power of the spell, and a flash of green light struck the dragon, only to be bounced off again.

The dragon's head turned to Aven, roaring angrily and spewing a stream of flames.

The rolling heat wave hit head-on, and Evan and several people hurriedly retreated.

The dragon's skin has a strong magical defense, defending against almost all known spells, with only the eyes being the weak point.

"Aven, what are you doing? using the Imperius Curse on the dragon?" Hermione asked, gasping, looking at him in disbelief.

"I'm trying to control it......"

"You're crazy!" Harry was shocked, "it won't work. ”

"The Imperius Curse can control the dragon, and it will work as long as the magic penetrates its skin, and maybe I should aim for his eyes, which is the dragon's most obvious weakness. Evan waited until the flames had diminished, then he raised his wand and aimed it in the dragon's eyes, shouting again, "Out of the body!"

In the next second, the green spell struck the dragon's gray eyes.

The spell didn't bounce off, and nothing seemed to happen, but in an instant, a tingling sensation poured from Evan's brain into the wand.

Succeeded, Evan managed to use the Imperius Curse on the dragon.

Unlike when he had controlled Bellatrix and the old goblin just now, he also felt a powerful, strange, and irritable thought rush into his mind. Stimulated by this thought, his head ached violently, and his veins even jumped up and down because of the huge impact.

The crazy thoughts that poured into Aven's mind were fleeting, and Aven felt a tremendous pressure that made him almost out of breath.

But he did succeed, he managed to control this fire dragon!

If this matter is known to other wizards, it will definitely cause a sensation, just look at the expressions of Harry, Hermione, and Elaine.

"How's that, Aven?, it's impossible, the dragon has a lot of magic, and almost no magic can do it harm. Hermione said, "It says that it would take dozens of wizards to use magic on it in order to inflict damage on dragons, and I've never heard of a precedent for using a Imperius Charm to control a dragon, even if it ......."

"I made it!" said Evan calmly.

"Even in China, where there is a legend of dragon control, it is not ...... What did you succeed in? you managed to take control of the dragon? Oh my God!" Hermione's mouth opened uncontrollably.

Harry and Elaine also looked at Evan in disbelief, they had never heard of anything like this.

"yes, I made it, get up there, climb on its back, let's get out of here. Evan said.

He jumped down and climbed onto the dragon's back in the crook of its hind legs.

The dragon didn't resist, it didn't seem to sense Aven, or that it was really under control.

It wasn't as grumpy as it used to be, but controlling a dragon was a drain on Aven, and he resisted the pressure to get the others to come up.

The scales on the dragon's back were as hard as steel, and Evan stretched out an arm, and Hermione tugged at it and leaped on.

Then he dragged Elaine up again, and Harry climbed up and sat behind them.

"Hold on!" Aven leaned out and shouted with his wand at the beast's heavy shackles, "Loose and strong!"

The chains that hold this dragon are free, and it is free!

With a roar, the dragon stood up, spread its wings, and rose into the air.

Evan clenched his knees, clutching the jagged scales as the dragon roared and flew into the air, its massive wings whirring.

"Aven, where are we going?"

"Go down there, Vault One. Evan shouted, still unrelenting about Salazar Slytherin's vaults.

He controlled the dragon to turn around, swinging his wand heavily.

Boom, boom, boom, loud bang, Evan blasted open the tunnel.

The dragon opened its mouth and spewed flames to help him, and the entire tunnel collapsed......
