One should know that anything could be posted as a task in Real Delusion as long as the chances of completing it weren't zero!
Even if a senior member of Real Delusion posted a task that needed the assassination of a country's president or kidnapping the daughter of a billionaire, the executive members of Real Delusion would still approve of that task.
But whether a member of Real Delusion would accept that task or not was another story. But it was likely that they would accept that task as long as the reward compensated for the difficulty of the task.
Deus found out that Real Delusion wasn't different from a mercenary group since they accepted any kind of task as long as the rewards given for the completion of the task were enough to compensate for its difficulty.
Because of that, Deus planned to use that to his advantage. He was well aware of how difficult it was to exterminate a first-rate clan such as the Luo Clan.
