Wu Gang indeed had something to say to Sang Lingzhu, but even he found it somewhat absurd, so he didn't know how to broach the topic.
The reason Wu Gang hadn't mentioned this matter to Sang Lingzhu was because of this.
Otherwise, he would have spoken to Sang Lingzhu last night, with no need to wait until now.
As for the issue Wu Gang kept grappling with about whether or not to tell Sang Lingzhu, it was, naturally, the fact that he had inexplicably become the Young Hall Head of Shuixingtang, a branch of Tianzong.
It wasn't for any other reason but if Wu Gang accepted this matter, he would definitely have to make a trip over there.
You see, Tianzong wasn't like Yunling which they had visited before; this trip's duration and the amount of work awaiting him were complete unknowns.
Wu Gang himself was unsure, so he didn't know how to start this conversation with Sang Lingzhu.
