So yes, the R-18 chapter will remain locked until the goal is fully met in a single day.
I just want to clarify because some of my readers seem a bit confused about the 600 power stones requirement. Here's how it works:
I already posted Chapter 10 as the reward for the first 300 power stones.
That left 300 stones remaining to unlock the bonus chapter, which you guys eventually reached over the next few days.
Hitting that total unlocked the bonus chapter, which is literally the next chapter after this.
However, the R-18 chapter works differently:
It requires 300 power stones in a single day to unlock.
Last time, you guys reached about 139 stones in one day, which is great but it didn't meet the daily goal.
So until that daily goal is reached, the R-18 chapter will stay blank.
Ahem… so… for those of you who just can't wait for the R-18 goodness… 👀
Well… there is a secret shortcut.
Where the spicy chapters are waiting… hot, ready, and way ahead of everyone else.
Y'know… for research purposes.
