Seeing that wisp of blue smoke, Li Dai's gaze narrowed. It felt vaguely familiar. Back before she entered the sect, the time she recognized her maternal grandfather, right before the Red-Masked Man died, he had also turned into a butterfly and flown away. It bore a striking similarity to this blue smoke—both served to carry back the final piece of intelligence before death. Though she didn't know why others couldn't see the blue smoke, it was presumably due to some secret technique of the Duan family. After all, with countless techniques in the world, she couldn't possibly know about every single one.
Watching the blue smoke fly toward the Duan family's leader—a middle-aged man—she didn't know what message he read from it, but his gaze toward the Gu family members turned a mix of hatred and wariness.
Li Dai didn't dwell on it too much; she simply noted the matter down, intending to remind the Gu family members later.
