Xiao Qiao took after her mother when it came to appearance, her head was a bright crimson. But unlike her mother, she had difficulties concealing her appearance and had to wear a talisman at all times to help disguise her nature.
She was just out in the city when she heard the news of Master Zhang's return. And Xiao Qiao was on some important errands for Lord Su (which mostly consisted of buying random oddities for his upcoming party) so she wasn't in a rush to return to the viscount's manor.
That was fine, she was bound to catch him when she returned and pass on the news that He Nao had entrusted her.
Which was why, she really had to do a double-take when she thought she spotted two people arguing on horseback, making their way out of the city rather than in.
