A Tiny Debt

After initiating the S class Inheritance quest, Han Ying Xue laughed her head off as she went off to complete it. She had the big pervert Battle Companion with her as her tank, and she herself could heal at an outstanding rate. Han Ying Xue now had the ability to fight any boss below Violet-Platinum Tier all by herself, as long as the boss fight does not have a time-based mechanism.

That being said, if she is patient enough, she could fight alone. In fact, she had always been calling for Zhang Yang to help her do the rough work. It was somewhat like working for his wife. According to Han Ying Xue, she would rather do something fun with him instead of wasting time killing monsters alone.

No matter what class of Inheritance quest it may be, the first few initial quests should involve running around to talk to a few NPCs first. Hence, Zhang Yang was free to do his messenger quest while Han Ying Xue did her menial errands.
