Arthur and Malz devised four hand gestures to deal with different situations—
Pinky: There's something, but not dangerous.
Ring finger: It's dangerous, be alert.
Index finger: Very dangerous, go all out.
Thumb: Extremely dangerous, prepare to run.
The presentation of the four fingers could include, but was not limited to raising, stroking, tapping, and so on.
As for the middle finger?
In the world before him, raising the middle finger held the same meaning as Arthur knew it, and sometimes, it was even more expressive.
Especially when Arthur saw Marinda flipping the bird, he couldn't help but think off-color thoughts.
But Malz wouldn't at this moment.
The police chief, noticing Arthur tapping his index finger lightly on his sleeve cuff, instantly tensed his muscles. Almost subconsciously, the chief's gaze turned toward the window—
The White Bird District, which had just experienced an explosion, was still eerily quiet.
