... Consciousness? Psychology? I for one want to say "That's Impossible to do!" but then again, what is consciousness anyway?
One might say it's the different stream of thought that represent your self and the world; The awareness of "you" and the world. But other with more spiritual approach would say that it's the third part in you who represent who you are; To be more exact, it's your "soul".
Two idea that seems similar, but have different meaning and inference. If i were to go with the first idea, this story would go as BS, since you "consciousness" is actually just a product of our experience. How could you "ripped it appart" from the body when the body would just produce another consciousness. But if i were to go with the second idea, this story would also go as a BS, since even if it's the so called "soul" that have been taken, that means the world technology already advance enough to touch the realm of metaphysic. If so, Why the fluff they still bother with things like this? It just doesn't make sense...
So in the end, i can't really say anything other than that this plot is BS unless: A. It's a fruit of demon summoning or any other "fantasy" aspect, B. The fluffling country is stupid enough not to double, triple, or even quadruple check "Hive" for their technology that went to the market, C. The government have silently "collapse" and the country is basically under control of the "Hive", or D. It's a manhua and it's supposed to not make any sense and i sould just enjoy the story
