At this place, Friedrich Engels and Karl Marx were casually having a conversation while drinking beer.

"Engels, don’t you miss your wife?"
"How could I not miss her, you bastard? But what can we do? We can’t go back until we finish the tasks that the Guild Master assigned to us or until we get the recall order."

The "Guild Master" mentioned here was, of course, Fabio.

Aside from that, they were talking about things that could easily get them executed for treason in the Lyon Kingdom, but neither of them seemed to care much about their surroundings.

This place, outwardly a trading company, was actually the revolutionary headquarters with only the loyal retainers of the Rothschild family as its members.

Security was tightly maintained here, and being overly tense would just be a waste of mental energy.
