Jiang Chen had previously been assassinated at No. 1 Manor, so this place was far from safe.
Even though Zhao Anguo had stationed a security team here, if a major power really wanted to carry out a decapitation strike against him, it would be hard to defend against.
After all, this was just a civilian residential area, and there was no way to prohibit people from coming and going, nor could everyone be checked.
As Zhao Anguo said, even a suicide attack wasn't out of the question.
