To cater to one's interests, is to find the other party's preferences and concerns, quickly bringing the other party closer to Zhou Xuan.
Feigning strength means Zhou Xuan pretends to be someone else, and if the other party falls for it, they will believe his identity in an instant.
That Bi Fang's fire is precisely Zhou Xuan's "catering" to Mr. Bai Liu; no storyteller could possibly ignore the arrival of their ancestor master.
And the details Zhou Xuan imagined for himself, like "the figure resembling a crane," "Bi Fang's voice," and "flashing forth from the fire," are all groundwork for the "feigned strength."
Once the feigned strength is projected, Zhou Xuan becomes the real Bi Fang in Mr. Bai Liu's eyes.
Both strategies of the Colorful Play Hall were laid bare, and even if Mr. Bai Liu wished to doubt Zhou Xuan's identity, he was still a part of the performance, with no ability to question it any further.
"Bai Liu bows to the Ancestor Master."
