actually"furnace" is already the right term. you can read more cultivation story
I meant the phone metaphor not furnace, girl did you skip the intro
And the charger thing. Where did you get the furnace from when it is a super common term. From all things how did you think I referred to that??
Wait, did you not check the date of my comment and thought I referred to the newest chapter or sth?
you're right i didnt cross check with the update time i also no longer remember what's in prologue
My guess is that author tried to make the concept easy to understand. The problem is that the original concept of dual cultivation or getting energy from another person is easy and this metaphor made it actually more confusing!
