Black Curtain
Sam and the team reached the realm where the assassin organization's branch is.
The organization is actually disguised as a merchant association. And they are called the Black Curtain Merchant association.
Everyone knows they take jobs for killing people, but nobody dares to confront them, in every place, they are right now, they control the underworld and even the local governments have to comply.
If they were made known about Sam's arrival because of Hou Yi's stupid attempt to delay Sam, then things would have been really troublesome, as they had a great experience in going to hiding and fight long-lasting annoying battles.
But luckily the team managed to cut off the chain when they dealt with the last organization that are responsible for spreading the news to others.
