Hi and welcome to Extra's POV.
For those who haven't started reading, I hope you have a good time. And for those who have read the book, I hope you enjoyed it.
Either way, I am here with a few goals that would help you unlock bonus chapters.
POWER STONE GOALS
For every 100 power stone, you get a bonus chapter. For example:
100 PS = 1 chapter
200 PS = 1 additional chapter, making a total of 2.
300 PS = 1 additional chapter, making a total of 3, and so on.
So, keep the power stones coming.
GOLDEN TICKET GOALS
The GT goals is the same as the power stone goals. This means that for every 100 golden ticket, you get a bonus chapter.
And remember, the goals are subject to change, so I recommend checking back, at most, once a month.
