The items these top levels hold in their hands are truly plentiful; just a few casual exchanges and they've settled matters.
Gu Xi listened, given what they're offering, he indeed has a chance to obtain the Death Decree skill.
As for not getting it, that's just Gu Xi's bad luck, and no one else can be blamed for that.
Regarding other rewards, those were the ones promised to Gu Xi from the start, allowing him to gain skill experience up to level 4. This was initially promised in the Ghost Soul Pass Trial Ground, or the second floor of the Rising Sun Magic Tower, or the Forbidden Book Area in the Radiant Library for access for three days.
Only now, it's quite decisive, with everything open to Gu Xi. As long as he has the time, he can improve all of his skills to level 4 here without any issue.
This is an investment in Gu Xi, as well as a way to win him over.
