Dumbledore was a great wizard, but he still couldn't avoid making mistakes.

At this moment, secretly calculating the amount of mana that Dumbledore had just lost, Louis personally felt that the most serious mistake he had made before was undoubtedly to pay too much attention to the part of Grindelwald's mana that remained in the vault, thus ignoring the defenses that Delphi had arranged for Voldemort's Horcruxes.

You know, compared to Grindelwald, who still hasn't shown fangs, Delphi, codenamed "Bu Bird", is obviously more like a villain.

Failing to learn the lessons of the wolf's blood potion and ignoring Delphi's abilities, Dumbledore's mistakes made Louis and the others return in vain, in addition to making their trip to the Gringotts vault seem meaningless, but also adding a lot of nutrients to Voldemort's Horcruxes, completely contrary to Louie's original intention.

Therefore.

It wasn't until Louie followed Dumbledore and Snape to say goodbye to the goblins of Gringotts and returned to the Smith family castle where his family and friends were located, that Louis sighed silently in his heart:

"Ugh..."

"Originally, I thought of using Dumbledore's power to completely destroy Voldemort's only remaining Horcrux."

"Now it seems that the destruction of Voldemort's only remaining Horcrux cannot be borrowed from someone else's hands, Dumbledore and Grindelwald are lucky that they can not cause trouble for me!"

Secretly saying a sigh of relief, Louis once again politely said goodbye to Dumbledore and Snape, and then used the hidden magic of the second turn in the Snape Distillery mark to perceive, and soon saw that after the two returned to Hogwarts to separate, Snape, who was in a bad mood, simply retracted back into the laboratory and continued to prepare the antidote to the wolf's blood potion.

Instead, it was Dumbledore.

He secretly re-infiltrated the vault of Gringotts, wandering outside the vault containing Voldemort's Horcruxes for a while, never reopening the vault and stepping inside.

And Louis was able to obtain this information, thanks to his arrangement outside the vault, and some of the three turns of silent magic were hidden in the body of the fire dragon guarding the vault.

At last.

By the time Dumbledore, who had been frowning at the vault in front of him, turned to leave.

"Hum...."

A huge magical force suddenly enveloped the entire vault, converging into a lune letter full of mysterious power, which gradually merged with the lock of the vault door.

Seeing that Dumbledore did not hesitate to use the magic of the past in order to block Voldemort's only remaining Horcruxes, and suffered an extremely terrible magic backlash, Louis couldn't help but squint his eyes slightly, and then analyzed in his heart:

"On the surface, it seems that Dumbledore means to use the magic of the old days to prevent anyone from reopening the door to this vault, and completely seal the ring of Marvolo Gaunt, which is a Horcrux, inside."

"But..."

"Think about the entire wizarding world, Dumbledore can be said to be the only person who has the same understanding of the old magic system as Grindelwald, so the old magic that Dumbledore is using now has another meaning?"

Could it be that the underlying meaning of his expression was that it could be used to defeat the magic of the old days..... Only the magic of the old days? ”

As soon as he thought of this, combined with his own understanding of the magic of the old days, Louis seemed to have received some kind of enlightenment, and suddenly shifted his "gaze" to his own spiritual world, clicked on the video stored in the mental hard drive, and browsed a book of old magic from the Smith family.

………………

Meanwhile.

The other side.

United States.

Within New York.

Almost at the moment when his magic power was accidentally devoured, Grindelwald, who was far away in New York, felt something, and immediately put down the plan he was about to carry out and came to a private house in Queens, New York.

From the outside, the house here is obviously an ordinary house, but in fact, it is inside.

The entire mansion is intertwined with countless elaborate magic arrays, in order to prevent other wizards from exploring, or discovering the secrets hidden in the mansion, and rescuing the prisoners of Grindelwald's secret suppression.

As the shaper of the house, Grindelwald is naturally the only one who can ignore the many magic arrays and enter and exit here freely.

And when Grindelwald returned to the house, tapped his finger on a wall a few times, and went deep into the end of the tunnel behind the wall, his eyes were fixed on the curled figure in front of him, and a charming smile appeared on his face, and he greeted:

"Hey!"

"Tom, I haven't seen you in a long time, how are you doing?"

Who is the guy who can be regarded by Grindelwald as a wizard of the same level, aka Tom?

It's the one that most wizards don't dare to mention!

The second generation of the Black Lord!

Voldemort!

However, at this time, Voldemort was in a very difficult situation, and he felt that his weakened soul needed to be attached to the body of a python in order to survive, and the python he possessed was the blood-cursed orc Nagini that Louis was familiar with.

Then, as Grindelwald's greeting echoed inside the prison, Nagini's originally cold eyes suddenly showed a bit of pain, and his curled up thick body also twitched violently a few times, and then a weak, hoarse voice sounded:

"Thank you for your recent care, I.... Good recovery. ”

"It's good to be recovering."

Grindelwald casually conjured a chair to sit on it, and said with a satisfied smile: "You are indeed in much better condition than before, I remember that when I first found you, you were used to communicating with people in a parseltongue, and now we can finally communicate in English." ”

"By the way, I didn't have anything else to do with you today, I just wanted to tell you to your face, Dumbledore has discovered your secret and is looking for the Horcrux you made in the first place."

Voldemort was silent for several minutes.

A few minutes later.

"Dumbledore was a coward, he never had the guts to fight people head-on, he only knew how to hide behind a group of rubbish and play some intrigues. His personality is not at all like a Gryffindor, but more like a pure Slytherin. ”

"So, what poor little fellow was bewitched by him and willing to work for him in search of my Horcruxes?"

"Is that the Silent imp you're interested in?"

"It's not."

Grindelwald shook his head and said, "It was Dumbledore who went personally, and your daughter did a good job, which made Dumbledore's guy suffer a lot." ”

"Daughter?"

"Huh!"

Listening to Grindelwald talk about Delphi, Voldemort who needs to cling to Nagini to survive, there was a sudden more complicated look in his eyes.

Because.

He knew what Grindelwald's purpose was for his visit.

So, knowing that he was under the control of Grindelwald, Voldemort took a deep breath and manipulated the little strength he had finally recovered to condense on Nagini's head.

The next second.

"Hum...."

Traces of the magic of the past are revealed.

A phantom condensed by magic power then appeared in front of Grindelwald, making the smile on his face even thicker!

"Tom...."

"I suddenly want to see what you looked like when you were resurrected!"
