@sssr I'm surprised they aren't all dead after a few years if it's indeed such free estate that anyone can kill anyone without repercussions.
Good servants are hard to find and school further. And then someone can just kill the servant and you can't do anything about it. No wonder the imperial dynasty in China was a laughing stock for the West and ultimately collapsed under the pressure of the Japanese, communists, and CNP. I knew it was bad but I had no idea it was that bad. I stand corrected, but I will still keep thinking the guard was especially prepared by the ultimate mastermind to keep an eye on anything abnormal that could threaten the plan. If you look at the plan as a whole, it was exceedingly carefully crafted over a long time, from seemingly independent pieces. It would only make perfect sense they would also try to remove the chance of sudden disturbances with a simple solution. It's just a lookout. Great many criminal operations use lookouts because they are effective, valuable, yet cost practically nothing.
Oh, since the guard is a free person as well... You know what his fate is going to be. Tough luck.
