The river's hints are certainly not that simple. Simple, is Li Zhiyuan.
Because in life, there are few people and things that can truly matter to Li Zhiyuan.
This is his flaw, which makes it difficult for him to trigger causality, so he needs Tan Wenbin and the others to help him engage.
This is also his strength; he can stand from a third-party perspective to examine these clues, summarize, and explore patterns.
However, this Professor Zhu before him is an exception.
Li Zhiyuan himself had long discovered that he has a higher level of acceptance and tolerance for certain specific groups.
Professor Zhu had gained Li Zhiyuan's approval, and the young man was willing to interact with him.
Others have to sift through dozens, hundreds, or even more causal clues every day. For the young man, the number is extremely limited; it took much effort recently to accept this lead, and it turned out to have issues.
