A few days ago when Ye Qian had met Huang's mother, he could feel that she wasn't completely well and had some discomfort.
And since the chubby little girl was his daughter's friend and he also had a simple Spiritual Energy artifact from all the pieces he made that day, Ye Qian thought that it won't hurt to gift it to the little girl.
The hairpin that Ye Qian had given to Huang wasn't a protective artifact and thus it was kept with him since he had made others for the sake of his little daughters' protection.
Initially, it was made from the first few scrapes of the metals since he wasn't able to completely mould it with the help of the phoenix flame that Feifei was emitting while helping him make the ornaments.
But since it still had a simple formation that could attract spiritual energy from around, he thought that it would be good for the little girl's health as well.
