How to increase knowledge?
------- Sorry, you can't upgrade at the moment; Your current level is level 9, with a total of 1,427,745 yuan in membership coins, 290 knowledge points, 269,864 physical strength, and 25,845 charm points. There are still 26 knowledge points left before reaching level 10, so keep up the good work! ----That's it. I just spent two million to buy something.
