Fang Mu had previously informed She Wan about Shui Miao and Golden Bull's request.
In the past, She Wan had seen Shui Miao altering his appearance through Noface Star Paper. The old man in front of her was clearly not Shui Miao.
Upon hearing Fang Mu refer to him as an 'old friend', She Wan quickly guessed that this old man was a major figure from the Starwheel, one of the twelve main constellations, wielding the power of the Golden Bull constellation.
On a normal day, She Wan did not interact much with the twelve official members who sat on the Golden Chair in the Starwheel.
The few with whom she did interact did not include the Golden Bull.
She Wan was uncertain why the Golden Bull had transformed into this state, using the ancient genesis method to transplant polluting substances into his body.
Even though Golden Bull was an official member of the Starwheel, she was also part of the Starwheel.
She was somewhat wary of this new Golden Bull.
