This trick is useless against her.
But it would be useful against other people who were not as perceptive as her.
Because Feng Ao Si's battle has always been direct and most of his opponents were not like Old General Han, Feng Ao Si had never remembered this little incident.
He tried to consult his younger brother and Feng Ao Kuai also told him that this kind of trick was pretty good.
But he would need to practice it.
Feng Ao Si didn't really like it and eventually never actually practiced it. He just tried to defeat Nan Hua in his usual ways and then got defeated.
The others also didn't say anything to him again.
So this matter was slowly forgotten.
After all, it has been so many years ago.
