Wang Longhu coldly watched their actions, his body had already started to hold his breath.
"Cough, cough, cough..."
Within five seconds, all the scientists in the laboratory fell unconscious, completely losing their ability to act.
Wang Longhu was just about to walk to the window to break the alloy roller shutter wall and escape, but at this moment, a group of armed personnel suddenly rushed in from the outside of the door.
Each of them held something similar to a pesticide sprayer, the long tubes aimed at Wang Longhu and began to fire.
A large amount of ice-blue powder roared out instantly, sweeping towards Wang Longhu completely.
"Not good!" Wang Longhu hurriedly grabbed a table to block in front of him.
He didn't know what these blue powders were, but for some reason, he had a faint feeling that these blue powders might be even more dangerous than bullets.
