Director Ji's move was destined to fail.
Faced with surveillance as pervasive as a net, any scheme is doomed to be aborted; it's a given.
At the banquet, anyone, whether going to the restroom or entering less crowded areas, becomes a target of surveillance.
This applies to Director Ji, and even more so to others who are under tight surveillance.
When Director Ji appeared near the beverage area, he had already become a suspect. The waiter who brushed past him, leaving the beverage area, was none other than Yang Yan in disguise.
At that moment, Yang Yan, following orders from Ye Fan, deliberately left the beverage area, intentionally creating an opportunity for Director Ji.
It was up to Director Ji to act—doing nothing would show he's overcautious, while any reckless action could lead to him becoming a prisoner.
The facts proved Director Ji was indeed the mole; his actions betrayed him.
