Gu Qingyao waited in her own room where she hid in the interspace to prepare the resources.
She divided each into smaller portions just like how she did in preparation for bartering. Previously, she and Mo Beihan visited so many places and not many resources were left in her interspace. Moreover, the capital had a very high demand, so she would prepare the items when she had time.
The next morning, Gu Qingyao went out and dressed normally. But when she was near the black market, she found an empty alley where she hid in her interspace to change her disguise.
When she was out, her outfit had already changed.
There were plenty of empty, old streets like these in the alley, and Gu Qingyao could find one anytime.
