Especially the strong aura of an old case handler that An Yan exudes, very genuine, unlike Fang Ze's half-baked demeanor. This is why, as the interrogation progressed, Qingping began to increasingly believe An Yan's words: She started to suspect this was a federal dissatisfaction with He Weidao, intending to take action against him, leading to a bit of panic within her heart.
Thus, under An Yan's excellent interrogation skills, this investigation ended quickly.
Throughout the process, Fang Ze was always ready to intervene and rescue An Yan, but perhaps because women, especially beautiful women, are good actresses, Qingping truly believed An Yan was an investigator sent by the Federation, without resisting at any point.
With the investigation concluded, to prevent He Weidao from knowing about the investigation, Fang Ze showed no mercy, directly issuing a cleanup order to the Fiend Codex in the Holy Reformation Room while reading the interrogation report.
