Girl, I feel you! I once had to sleep with nothing but a thin sleeping bag out in the middle of winter, when I woke up the next morning I could literally feel nothing below my knees. Walking was weird, scary, and oh so unsteady ?
@Soumanou I looked for it, it's Impregnable Demon King Castle ~The Black Mage Who Got Kicked Out of the Hero Party Due to His Unnecessary Debuffs Gets Welcomed by the Top Brass of the Demon King's Army - chapter 12 It might be wrong, please check.
