So today confirms that you get 1 free chapter per day from the moment the three novels went premium (chapter 690 for immortal mortal).
If you unlock the next chapter with SS it is still counted in the free chapter pool, this means you get NO free chapter the next day.
This is a significant downgrade to the free reader experience, it also proves that QI is trying to further monetize the free user base as the only reason for changing the free model is to "persuade" people who used to be able to read 3 chapters per day to buy SS in order to continue doing so.
People saying this is just patreon moved to QI are full of it.
