Close to ten armed personnel charged into the house and apprehended the people living inside. A tool resembling an Electro-Magnetic Pulse grenade was also detonated when they got inside to jam all the electronics around that 1-km perimeter for safety reasons.
And since Zhang Qin Feng's weaponry operates using entirely different mechanics, those weapons like Thunderbolt, Luna Device, and more were operable as usual. Only the tool that was made in this modern world was affected by the EMP grenade.
The same operation happened all over the City of Mari and Anna. Close to sixteen residences were broken through, and at least a hundred people were captured. From the initial narcotic test and house search, it was reported that they're all drug addicts and people involving in either drug production or distribution.
