When Darren and Hermione return to his house, Twinkle is ready to greet his master, and at the same time, there is a person waiting there, Penelope. Pen, fun, and www.biquge.info

"It's great that you're back," Darren was overjoyed to see Penelope, because when arranging the work, he told the other party that it was very important and that he must supervise the whole process and make sure that it was done before returning to England.

"That's done," Sure enough, Penelope's job is reliable, "according to what you said," she recounted briefly, "the thing we found last time in Atlanta, I found some engineers who had retired from the factory that produced it, used memory magic to convince them that they were working for the secret department, and then took it apart and took out the fission part, and reassembled it, and after inspection, they all thought it was working properly. ”

Specifically, Penelope found someone to disassemble the fission device used to trigger the nuclear fusion reaction in the hydrogen bomb, that is, an atomic bomb, and restored it to working condition, the reason for this is that, on the one hand, because the original power is too great, it is completely unnecessary, and on the other hand, the hydrogen bomb is too long, although the structure of the bomb is still intact, but the most important part of it, the nuclear material will deteriorate, unlike ordinary ammunition, radioactive materials have a half-life, even if they are not placed, it is constantly decaying, so as to continuously reduce the effective content, which will not only reduce the power, if the critical value is broken, it will also lead to the failure of nuclear weaponsIn contrast, uranium and plutonium used in fissile devices are much more stable.

Of course, it is only relative that nuclear materials will deteriorate and become ineffective, after all, the time required can fully meet the normal needs of such weapons, and even conventional weapons also have the problem of shelf life, not to mention the large number of auxiliary equipment on nuclear weapons, and it is impossible to use them forever.

In fact, because of the equipment upgrade, long before reaching the critical period, the nuclear material will be processed and reused in new weapons, that thing is very expensive, in a certain condition, the real bottleneck restricting the development of nuclear weapons lies in the acquisition of nuclear materials, the relevant theories and data are not a secret for any country-level forces, but from the isotopes mixed together to separate specific substances, the equipment and capabilities required are far beyond imagination, and because of the way it works, it is impossible to hide。

However, even with the atomic bomb, it doesn't make much sense to defeat Voldemort, after all, Darren can't throw it directly, it's too frustrating, even if the power is reduced, it will have to top several Hiroshima and Nagasaki, and in this magical world, what will happen is really hard to say, so this can only be used in the last step, in the case of breaking the cauldron, so ......

"We're going to Gringotts today," said Darren, as there were only three people in the house, and it was impossible for him not to talk to any of them about it, "to see if we could get into Bellatrix's vault, I heard from the elves when I was doing business there that she had one too, and that Lestrange was a pure-blood." ”

"Why?" asked Hermione.

"Oh, she hates me now, so let her have one more reason to hate me," Darren said casually, Hermione frowning, "You're breaking the law like that." ”

"Well, this law keeps Bellatrix and her husband in their coffers after they've both been sent to Azkaban," Darren shrugged, "Of course, it's Bellatrix herself the second time." ”

"What are you going to do, Gringotts can't possibly let you into someone else's vault," Penelope asked.

"With a polyjuice decoction. ”

"Polyjuice potion, do you have anything from Bellatrix?" Hermione looked at Darren, "and, even if it were in person, Gringotts would probably authenticate itself, just like your vault." ”

"Well, yes, I have this," said Darren, pulling a wand from his pocket, "I picked it up after the battle with Bellatrix that night." ”

"How did that turn her?" Hermione and Penelope's faces turned very ugly as Darren took out another thing, his severed right hand.

"This is also Bellatrix's, and it should be enough. ”

"But now that Bellatrix is wanted by the Ministry of Magic, how do you take her to Gringotts?"

"Ministry of Magic Wanted?" Darren laughed, "If the Ministry of Magic's wanted warrant is so effective, even if they can't catch the mystery man, at least the Death Eaters should have been caught, but it's not that they have broken into Hogwarts, not to mention that Gringotts is full of goblins, they and the Ministry of Magic, hum, they will definitely not be in trouble, but when you enter Diagon Alley, you have to be careful, Tom, the owner of the Leaky Cauldron Bar, attended Professor Dumbledore's funeral." ”

"Well, I'll go," Hermione said.

"No," Darren shook his head, "you have more important work, did you get that book?"

Hermione nodded, pulling a brown black-skinned tome from her pocket with a look of disgust, "This book details how to make Horcruxes, Secret of Cutting-Edge Dark Magic," she whispered, "I cast a flying spell and it flew straight into the girls' dormitory through the window of Dumbledore's study. ”

"The more we know about Horcruxes, the better," Darren took Cutting-Edge Dark Arts Revealed, stroking its cover, "So, now it's up to you to figure out what it's about Horcruxes, how it works, and what the drawbacks are." ”

"But Penelope can do that, too," Hermione said hurriedly.

"yes, though, she's not as good at reading books as you are," Darren handed Hermione the Secret of Cutting-Edge Dark Arts.

"Yes," Penelope said, "you have a very good memory, as I discovered when I studied Moody's two notebooks," and now that she has lost a lot of memory, let alone Hermione.

"But, if it's just Gringotts, it won't take much time, we can go together and come back and read the book again," Hermione insisted.

"That's right," Darren nodded, "but if you show up with me with Bellatrix, I'm afraid it won't be easy to explain." ”

"Why?"

"Because Bellatrix won't deal with us. ”

“…… What about you?"

"I went to Gringotts with her just to cover up, like move everything out of my vault. ”
