"Mr. Sharma, thank you for your honesty," Vizet said slowly. "At least judging from the current situation, even wizards' methods for dealing with Dark Magic creatures are mainly focused on containment."
"Especially Dark Magic creatures like Dementors. In fact, Dementors are on a higher level. Like Peeves, Boggarts, and other Dark Magic creatures, they are defined as 'Non-Beings.'"
"Non-Beings..." Malcolm Sharma's eyes flickered slightly as the letters Galen Claudius and Lyall Lupin had written to him flashed through his mind. They had contained similar descriptions.
"Galen Claudius and Mr. Lyall Lupin told me that compared with Dark Magic creatures like Red Caps, 'Non-Beings' such as Dementors cannot be destroyed."
"They also seemed to say..." He recalled the contents of Galen Claudius and Lyall Lupin's letters. "Even if you use the Patronus Charm, at most you can only drive them away."
"That's right," Vizet replied seriously. "If you only want to understand Dark Magic creatures, or understand 'Non-Beings,' the two gentlemen have already summarized it very comprehensively. I have nothing to add."
"Are there really no preventive measures?" Malcolm Sharma pressed, a hint of anxiety in his tone.
"If these so-called 'Non-Beings' cannot be destroyed, shouldn't their numbers keep increasing?"
"Actually, just like science, magic also has many secrets that cannot be answered." Vizet asked, "Mr. Sharma, you should understand that, shouldn't you?"
"Perhaps so?" Malcolm Sharma answered quietly. His identity as an agent of the North American Federal Bureau of Investigation made him take a relatively open-minded view of many things.
Vizet continued, "At present, what we know is that 'Non-Beings' such as Dementors remain at a relatively stable number."
"If an environment suitable for Dementors to appear exists, they can actually increase their numbers in a short time through something similar to 'reproduction.'"
Malcolm Sharma raised his eyebrows in
