A stalemate was something no dealer wished to see.
The arena duel was organized by Sun Yixie, who busied himself for a great part of the day, only for it to be thwarted by a mysterious man in a black mask. Understandably, he was quite displeased.
But regardless of his feelings, there was nothing he could do; the man in black had vanished without a trace, and he had no connections with Zheng Mukai and Ge Shi. Even if he did inquire about the incident, they were unlikely to tell him anything, so Brother Sun had no choice but to let it go.
It wasn't until later, after Sun Yixie had attended the Youth Hero Conference and returned to Xuzhou City, that he learned the full story through Miss Chuxue, but that's an aside for another time.
Now, back to the journey of Sun Yixie and Huang Donglai... They stayed an extra day in Xuzhou to catch the spectacle and then embarked on their journey the next morning.
