For Su Bai, his mission was straightforward: to attend the rendezvous normally, converse normally, make acquaintances normally, discern normally, and then, as normal as could be, proceed to kill.
However, for fat guy, Jie Bing, Monk, and Gyatso, their tasks seemed a lot more lax and arbitrary. The four of them hadn't arranged to lay an ambush near the hotel, with various Formations and Magic Artifacts at the ready, positioning themselves in a 1-2-3-4 sequence.
Because this wasn't an ambush, in fact, if they truly adopted an ambush posture, and if the other party was willing to respond, then the four of them, even if bound together, would just be setting themselves up for failure.
This was an operation primarily aimed at searching for clues—the spirit was "participation is what counts," and the extremely low objective and success rate gave Monk and his companions even more room for development.
