This goes without saying.
The most crucial point is that the magic he created, which covers the entire body with ice crystals, has very low magic power consumption if the ice crystals are not attacked.
Generally, magic is classified as either instantaneous or continuous: continuous magic requires constant supply of magic power, while instantaneous magic consumes magic power in one go.
Grandpa Qian of Bone-Touching is different; the magic he created is both instantaneous and continuous.
Why is that? When he uses this magic to enchant others, it's instantaneous.
Once it's broken, it's gone.
However, when he uses it on himself, it becomes continuous, allowing magic power to constantly repair the damaged ice crystals.
In short, he thought it was really cool, especially since he hasn't acquired a skin yet, so he always uses ice crystals to wrap his skeleton frame.
He looks like an ice crystal skeleton, very eye-catching and distinctive.
