If someone were to ask Bartlett, "Hey man, how does it feel to go from a living person to an Undead?" He would stroke his chin and say, "Well... to be honest, it's not too bad."
Yeah, it's not too bad.
His body is still the same, but his skin has become very tough, like a well-tanned cowhide, although it does feel a little cool to the touch. For an Adventurer, this is not a bad thing, at least it can help you to truly "cool down."
As for his heart, it can finally enjoy a nice long break. Even better, it can still surge with power after the break. His blood has turned into a highly viscous, mercury-like silver-grey liquid. This ensures that the blood does not freeze into sharp ice crystals in the blood vessels due to low temperature and pierce out of the body during movement.
His chest has also become calm, losing its habitual breathing motion, so Bartlett need not worry about whether his breath is fresh (although he rarely cared about this before).
