Jang Shin checked their pulses, there's no breathing left on them. Then he saw a hole in their forehead. Warm blood was gushing out of it.
Jang Shin could somehow guess what happened here.
When the lights died down, a spy from inside used the chance to release the smoke. When all the guards in the lobby were down, he let the men outside come in. Those men then shoot the people in the head so they won't ever wake up.
Just imagining that made Jang Shin's blood turned cold.
This group of attackers was truly ruthless. They killed the other party even though they were unconscious and have no means to fight. They spared no one alive. Even the receptionist was killed. With how savage these people were, everyone in the building was in danger.
Bang! Bang! Bang!
Consecutive gunshots sounded from upstairs. The security guards from upstairs finally become aware that there were intruders.
Jang Shin did not dally and climbed the emergency stairs.
