When Yan Xing had provided the militia and Werewolves with makeshift armor, it was a temporary solution, a measure born of a lack of time and money.
Now that he had money, such crude armor could no longer be used.
The makeshift armor could offer some protection against arrows and swords. However, when faced with the Steel Chains used by Werewolves, it was only slightly better than cloth armor and perhaps not even as good as high-quality hardened leather armor.
Of course, this was something that the now wealthy and influential Yan Xing could not accept.
After all, I am the invisible richest person on Earth; how could I equip my army with such shabby gear?
Moreover, with only so many soldiers in his domain, every injury or death was a significant loss.
So, when Yan Xing ordered armor for himself, he also purchased armor for the militia and Werewolves.
Although it wasn't titanium alloy plate, it was all made of good steel.
