One warning…
It was all it took for the entire elite squad to be wary of this specimen from a seemingly off-site experiment of the facility. When they read about Liu Xiaodan and his general behavior, everyone was dismissive of his level-five status; they couldn't see what was dangerous about this gentle face.
However, the past two encounters with him had proven them wrong. On the surface, they were only letting him realize that he was at a level-three status. That included immediate takedown at any possible harmful action and permanent tag of location.
What happened that morning in the Food and Leisure Hall was a miscalculated mishap to the elite squad as they decided to take their eyes off of him for a few hours to make sure the dignitaries were safe. However, what followed that time was him killing a newcomer… even if it was in self-defense.
