This unlocking of Free Chapters is very flawed. For all readers, it'll only be either reading Free Chapters everyday or reading Premium Chapters everyday. You just can't buy some, like 50, Spirit Stones, then read 4-5 Premium Chapters only to wait like a free reader in the end because the next chapter will only be unlocked after 4-5 days. The money spent end up becoming a waste.
Free Reader:
Day 1 - Read Ch1
Day 2 - Read Ch2
Day 3 - Read Ch3
Day 4 - Read Ch4
Day 5 - Read Ch5
Semi-Free Reader (Bought 50 SS)
Day 1 - Read Ch1 Ch2 Ch3 Ch4
Day 2 - Wait
Day 3 - Wait
Day 4 - Wait
Day 5 - Read Ch5
If I want to have a REGULAR daily Premium Reading, I'll have to always buy and consume Spirit Stones. Now if perhaps I stopped buying Spirit Stones after consuming a month or two worth of Premium Chapters, how many days should I wait for the Free Chapters to reach my current reading? Even disregarding the mass releases, that is still a lot of days of no reading, which can only increase dissastisfaction to this App and its Premium services and other such negativity.
I know this is disregarding the daily Free Spirit Stones. But these Free Spirit Stones are only good for 1-3 Premium Novels. Now how many novels do we actually read? And how many of them are Premium Novels and future Premium Novels? There are many good novels to read and if I want to read a 4th Premium Novel's Premium Chapters, I'll have to buy Spirit Stones CONTINUOUSLY because stopping midway will be a waste and will leave a bad taste. Being forced to spend money continuously like this for something I enjoy is something I dislike. It reminds me of the minds of numerous villains that I've read.
So, knowing the potential of buying Spirit Stones is something like this, I'll just read as a Free Reader and never buy any Spirit Stones.
