Chairman Deacon went on to present a rigorous strategy that involved using brute force to eventually either find or kill the Voider inside the Shionel Dungeon, or identify the Voider, and assassinate him outside the Shionel Dungeon to minimize risks, or overwhelm him with numbers inside the Shionel Dungeon where murder was legal.
He did not come up with brand new revolutionary ways of going about the investigation and search. The intelligence that Chairman Deacon had gotten in the last operation on the fourteenth floor was a fluke and stroke of good luck. He had not gotten that information through his own merits.
