Shortly after the discussion with Veronica in the Town Hall's office, Xu Feng ultimately left the remaining administrative work to her.
Now that he was the Guild Leader, he didn't feel the need to work like a slave he did in the past timeline.
Naturally, Veronica was left disgruntled and demanded for assistants.
However, when Xu Feng simply brought up the question as to who she got, Veronica's face quickly darkened and chased him out of the office.
The stakes in the Vanguard Guild were at the highest. She couldn't possibly entrust just any Tom, Dick, or Harry to become her assistant.
As for those who she could entrust, they were already entrusted with a different task by Xu Feng.
Thus, she lashed out and chased Xu Feng out because she was afraid of committing treason and rebellion if he were to remain.
