Yes, the 4 assassins hadn't been killed, they were just uncontrolably shivering as their blood vessels were being ruptured one after the other.
An invisible force was actually cutting their bodies repeatedly, and slowly turning them into nothing more than pasta drainers.
It was most certainly something terrifying to watch, but even more so to actually experience as their bodies felt like they were being scratched and not just cut.
Despite they had their faces covered, one could tell that the remaining two assassins were trembling in fear, especially one of them.
Nobody felt pity for them though, in their line of work returns were really great, especially when targeting special and high connected people, but at the same time the reputation was rock bottom.
No assassin would receive respect and relations if it were known to the world that he was an assassin.
