Hao Jian takes a look and is dumbfounded. A normal person's pupil should be black with white speckles, mixed with yellow inside. However, Boss Zhu's pupil is entirely occupied by black, vastly different from that of an average person.
The occurrence of such a change is definitely not normal. With a bit of reasoning, Hao Jian concluded that the cause might be poisoning. Boss Zhu's current state is most likely due to someone drugging him, rather than a mere physical ailment.
Thinking about the poisoning, Hao Jian first thought of Mrs. Zhu, as his guess was to place the source on her. In fact, everything Mrs. Zhu has shown seems to confirm this suspicion.
As for Boss Zhu's daughter, though she is somewhat sharp and domineering, based on her performance and situation, Hao Jian feels she is unaware of the incident; or maybe Mrs. Zhu's actions are unrelated to her, and she doesn't even know what really happened.
