Feng Ao Kuai had built his reputation on the battlefield.
He might not be very well known, but people knew that he was a stable person and not a hasty person. It was also with this in mind that Feng Ao Kuai chose to show his intelligence and stable side.
Because the Emperor needed a person who could be stable and smart enough to control the areas that previously belong to Zhang Xu Kingdom.
A reckless person was definitely a big no.
After conquering that area, what they needed was someone who could revitalize the business and many others that had been destroyed in war.
It also needed someone who was patient.
So Feng Ao Kuai was bidding his time while calculating other people's response. He was doing everything covertly and calmly because he believed in his own abilities that even if there was something wrong, he would be able to deal with it.
