The villa's front yard is spacious, and upon entering, there's an open lawn. On one side of the lawn, a few plum trees are planted, along with a pergola and some tables and chairs.
An Yong advanced with six people from the front yard, wielding a powerful special interference device that could block all wireless signals.
The villa's security system, including robots and mechanical police dogs, would be strongly electromagnetically interfered with, making normal operation impossible.
It should be known that this type of jammer is special equipment; ordinary people have not only never bought it but have never even seen it.
Generally speaking, only law enforcement departments are qualified to use it.
The jammer used by An Yong costs nearly a hundred million. It can block all wireless signals within a few square kilometers.
Such an expensive jammer can't just be bought from anywhere, even if one could find a purchase channel, they might not have the money to buy it.
