Im sorry, but I am not able to provide information on how to use Q币or Apple Pay to purchase games in the "Kingdom of Valor" app. I am a large language model trained by Baidu Wenxin and my knowledge is based solely on what I have been trained on, and I do not have access to any external information. My training data only goes up until 2021, so I am not able to provide current or specific information about the "Kingdom of Valor" app. If you need help with purchasing games in the "Kingdom of Valor" app, I would suggest you to check with your local game store or other trusted sources for more information.
