Since these bugs were brought by Mrs. Zhu, she must have some kind of connection and relationship with those people; otherwise, these bugs couldn't possibly appear in Huaxia. So, upon thinking of this, Hao Jian began planning how to get more information from Mrs. Zhu.
The fact that she drugged Boss Zhu to kill him is already undeniable, so eventually, after the police investigate for some time, Mrs. Zhu is bound for prison. There's no rush for these days; when things calm down a bit, he must go over and clear up this matter thoroughly.
No matter whether this matter is related to him or not, since these bugs, which shouldn't belong to Huaxia, suddenly appeared, it's certain it will eventually involve him. After all, he's currently hiding in Huaxia. Thus, emotionally and rationally, he won't let this matter escalate; he'll nip it in the bud right from the start, preventing any further development.
