Once Bing Xin came out of the slums, she didn't head to the Shan Family right away.
Instead, she went to one of the inns and rented a room before heading out to buy some things.
The things that she bought were…clothes.
As her mother had told her, she was to dress nicely and report back to the Shan Family Manor. However, the Shan Family never gave her and her mother any money in the first place, so it wasn't as if she was able to buy any good clothes.
The one set that she had when she went to the Falling Star Sect's sect recruitment was bought with hard earned money that she made on the way. If it wasn't for that, she wouldn't have been able to look presentable for the sect recruitment.
As she was shopping, Bing Xin took out the spirit stones that she had and looked down at them with an emotional look in her eyes.
Others might not be able to figure out what she was thinking, but it was clear to us what she was thinking.
