The branches and leaves of the trees here are excessively lush, making it impossible to find Long Feiyun escaping atop the trees so quickly.
Undoubtedly, Long Feiyun succeeded with his move. He sporadically emitted flashes of dark energy to confuse the sight and hearing of the five men, while he himself stealthily returned to the ground after escaping a certain distance. Although he escaped from the treetops, it didn't mean the treetops were safe; on the contrary, it was the most exposed place. Long Feiyun chose to escape upward out of desperation. It was an unexpected move that left the five men unprepared to pursue him atop the trees, but by the time they reacted, Long Feiyun had already returned to the ground.
