The target's house wasn't a strong fortress, and it hadn't even undergone any security modifications because the aim in buying this house in Germany was originally to enjoy life, whereas needing refuge was a more recent need.
It's the same with the car; if the target knew that one day he would become someone else's assassination target, he would definitely have got himself a bulletproof car.
But now, well, there's no way around it, Gao Yi and his team could only take things as they come, and the target had to just fend for himself.
The first move was to start a fire on the mountain, the second was to warn the target and those protecting him not to think about driving away, but instead to obediently run on their two legs.
The blaze flared up fiercely, but it was mainly the car that burnt fiercely; the actual room fires were not too big. However, no matter what the main structure of the house was, such a large fire would make people inside want to run out.
