The biochemical weapon that Paul prepared was actually not that fancy.
It's just a wide-area poisonous fog.
The poison could kill within fifteen minutes if the victim didn't receive an antidote or healing from healers.
The fog came from a bomb, and one bomb could produce quite a dense fog within a twenty-meter range. But if there were many bombs, it wasn't difficult to cover the whole front yard, backyard or even the mansion.
If the mansion had ventilation and other gaps, the fog could quietly seep into the building and spread more poison.
Each of the members brought one palm-sized bomb like this and also had one bottle of antidote, a filtering mask that could filter the poisonous fog's effect, and the corrosive liquid that had been used earlier.
