The armor that their city's military used to purchase, was generally made for men.
As for her armor, it was uncomfortable for a man to wear due to the tightness around the chest, so she later commissioned Master Zhi Lai to make a customized one for her.
However, the private customization of armor was extremely expensive, and thus, if Gu Chenyan had the opportunity to wear men's armor, she wouldn't use the custom-made one.
But the armor she had just purchased was a bit too tight, making her chest uncomfortable.
If it were any other woman, perhaps there wouldn't be a problem. However, the issue was that her chest was significantly larger. As a result, it could negatively impact her fighting prowess during battle.
But now, when Mo Huasong told her that this armor could be unisex, however, she was astonished.
Master Batian truly lives up to his reputation, to be able to multi-purpose the armor in adverse conditions.
