Sunlight shone in the canyon, casting shadows.
This was the south side of the canyon where the poachers had also come from, and now as they fled, they were heading directly towards the sun.
The sun hung high, and drones flew into the sky, borrowing the daylight's cover, coated in a layer of gold, making it impossible for anyone to discern exactly what they were.
Furthermore, frazzled by their desperate escape, the poachers didn't realize a drone was capturing their panicked expressions and postures, which showed up starkly in the machine's view.
It must have been a crime of passion.
Seeing the expression on the other's face for just a moment, Bi Fang realized this possibility.
If there had indeed been premeditation, they wouldn't be this frantic, and the time between the two attacks wouldn't have exceeded ten seconds.
Perhaps the spark that ignited the conflict was the argument that had just occurred. No, it should be said it was the last straw that broke the camel's back.
