"I was wondering if there was any more concrete evidence, even though the two points you just made were strange enough."
The elderly Duke, who was not much younger than Clevo, blinked and laughed self-deprecatingly, "I'm sorry. It appears that my curiosity is too obvious."
Simon shook his head, "I was coming to the third point. It's still the two oldest workers. One of them claims to have seen several black carriages at the factory one night, and faintly heard the whips and harsh shoutings. He is just an ordinary civilian, so there is no reason for him to lie."
"It seems that the conclusion is very clear."
Duke Mercury Core Fernan muttered in the cushions of his chair. He looked flustered when he noticed that he was being focused on. "Ah, I... I do think so, as what Simon said is very... very obvious."
