Du Leng's IQ and EQ were actually not low.
It was because everything had been smooth sailing for him since childhood, with a smooth academic journey, that he had achieved academic success that ordinary people could not reach in a lifetime at a young age. Therefore, his heart was extremely arrogant.
Arrogance leads to setbacks, and sometimes it even drives people to make cunning but foolish decisions.
Moreover, being constantly overshadowed by Zhou Can, he felt frustrated and wanted to regain his pride. Thus, going head-to-head with Zhou Can had become a perfectly normal affair.
In addition, Yang Chan maintained a very close relationship with Zhou Can while keeping Du Leng at arm's length with politeness, which made him very uncomfortable.
For a genius like him, when had he ever been suppressed in such a manner?
Especially when the one suppressing him was an undergraduate whose academic degree was much lower than his.
