Since they were working together, they naturally needed to display their capabilities so that King Yu would acknowledge them. Within the current imperial city, there were not many chances for them to display their capabilities. However, they coincidentally heard some rumors about this black-hearted store and that Hun Qianyun had once admitted defeat at this store as well. This was practically the ideal chance for them to display their capability.
Therefore, Wei Xiangsi came along with two of her Battle-King subordinates.
From Wei Xiangsi's point of view, Hun Qianyun, who looked like he had one foot in the grave, was defeated probably because he was incapable. However, just because Hun Qianyun lost did not mean that they were unable to win, especially when they found out that the owner of the store was a male.
From their point of view, there was no man that they could not handle.
