The visible target, Asai, is rumored to possess two map fragments in his hands. Just like the auction house being repeatedly attacked, Asai has also become a major target for various factions to spy on and investigate.
Now it can be eased a bit; Peng Bird and his crew stole the fake map fragments carefully prepared by Asai, thus diverting this trouble onto Peng Bird and the others. It's foreseeable that the situation will unfold with various factions keeping a close eye on Peng Bird's every move, allowing Asai to temporarily escape from their scrutiny.
This tactic of directing trouble eastward completely extricated himself. It is indeed a brilliant maneuver.
Yamamoto and Nishida had been kept in the dark until they heard Asai's explanation, which then made them realize the truth.
From start to finish, they didn't know Asai would have such an arrangement. Thus, after the shock, only a deep sense of admiration remained.
