Kung Fu Zombie thought he was interrupting Luzzeffe's ascension from 'broken chimera thing' to 'proper demon' by backstabbing him at the last second with the soulstone weakening poison he'd ordered.
However, Luzzeffe, being a properly paranoid mad scientist, had a back-up plan for that. Apparently, he decided to sit tight for a few and see how his servants would react to his apparent assasionation.
Now that he's seen that Kung Fu Zombie is a traitor and Crab-Claw McProtagonist and Weakling McBoobs both refused to go along with him and his plans, he's probably going to wreck Kung-Fu Zombie in a fight (since unlike Kung Fu Zombie, his fighting level is SKULL as opposed to 'increasing numbers' and he's a Demon instead of a Demonic Chimera. Plus, Kung Fu Zombie is kinda derpy faced and Luzeffe looks like Ozzy Osborn, which makes him way more metal than KFZ, so he'll obviously beat 'em in a fight) and fix-up or improve the other two, since, after all, he never ever allows his servants' hardwork to go by without compensaion.
I've got a private bet with myself. that 'Soul Shackle' is a bluff skill, too.
'oh yeah, I totes shackled your soul. Totes.' oO(Now, let's see who's actually loyal to me and who'll plot if I tell them 'i puts a geas on you')Oo'
