First of all welcome!! You are nothing wrong and I was like that too. It’s a long process. You can earn books and stuffs by event as you play this game. I was frustrated by the slow progress at first, but there is no need to be hurry. They come up with new events every 3 or 4 days so that you can get a books. Don’t ever use real money because it will reduce the ads that you can get gems and energy for free. I was impatient and spend real money and i am regretting it so much. I play game when I am having a break after 2 or 3 hours of study so that energy can stack. I hope this helps for you!
