Comments of chapter undefined of The Vampire King's Possession

I'm quite annoyed that privileged must be purchased at this juncture. I paid for and read 538 chapters only to be slapped with yet another $30.00 worth of purchases. This could quite possibly be the 3rd book I drop off from reading when almost completed. Web Novel and many authors are ripping people off. Really great books while still in the writing phase only charge 6 to 8 coins per chapter. This isn't even on their level. I've endured this far out of boredom.
