Hello,
in the app you can earn rewards with reading time.
I would find it nice if you could get more rewards there, this week im at 1235 mins reading time, last reward is at 600 mins.
have a nice day
Reading Rewards
Same lmao i can go for 3000 + minutes coz i lack spirit stone for unlock 
i reread a novel like 2 times a day
It seems you only get up to 600 mins per week rewarded
I thinks the reward system is a little to strict.
5 Stones for reaching 30 min
5 Stones for reaching 90 min
5 Stones for reaching 120 min
5 Stones for reaching 240 min
10 Stones for reaching 360 min
10 Stones for reaching 600 min
I'd say cut down the reward 1 Stone every 10 mins but don't limit it to only 600 mins max.
If there is a need to limit the max hours then do 120 min limit per day. So the max earning per day would be 12 Stones. That would result in a per week earning of 84 which would be 44 Stones more. Which also would mean the reader would at least read 240 min more per week.
It would also mean the reader would have 37 Stones plus the check-in ones per day then the reader could read round about 4 chapters at a value of 9 Stones per day. 4 chapter would mean you could read 4 Premium novels which update a chapter per day simultaneously.
