[Blais: What is that thing? EBM has silently paralyzed this city!]
[Munemasa: Impossible...this is just a theoretical technology, and EBM has turned it into a weapon?!]
There is indeed a record in Munemasa's database: this is the technology of directional electromagnetic interference using the ionosphere within the atmosphere combined with orbital deployment capabilities—
To use this attack method, there must be precise deployment capabilities for large spacecraft in low Earth orbit.
Due to technical requirements, this spacecraft must be equipped with nuclear reactor-level energy, functioning as a massive particle accelerator, capable of controlled, directional generation and emission of these charged particles and auxiliary control lasers, disturbing the plasma layer in the atmosphere, forming a chain reaction, thus blocking the entire region's communication with the outside world!
