The smoke obscured the vision of Murong Yue, Lin Fan, and the two people in red holding this Gold Ranked Assassin.
While this was happening, there was an explosion from the pile of assassins that the other people in red had been guarding.
The bodies in that pile suddenly flew out in all directions, catching the people in red off guard. At the same time, with that sudden explosion of bodies, there was smoke that came from the center of the pile that quickly filled the surrounding area, blocking off the line of sight of the people in red.
As this smoke spread, there was a figure that quickly moved through the smoke before disappearing.
When the smoke finally dissipated, there were the bodies of the assassins that were lying all over the ground with the people in red standing over them with their weapons drawn, prepared for anything that happened.
