Bruv, what kind of fascists bullshit. That wasn't even an interrogation, that was torture. He literally complied immediately and gave him the truth, but he assumed it was a lie and temporarily kills him, and when he clearly shows honesty to the same answer again, he still assumes it's a lie. What does he really expect though? Like, what was he expecting him to say? Details on where he came from and such? That's way too wishful thinking. Plus they have a lie detector, what the fuck. Anyways, MC is pretty much fucked. Forced to be made a weapon, will need to struggle to find out what happen to him. Probably related to his brother, probably related to his power he had even when he was human. Kind of weird that it turns out to be time travel too(?). Either that or that classic theory that advanced technology has always existed but was never revealed to the public.
