King of Glory Slow recharge means to recharge through some unofficial channels or ways to obtain more coupons or other game props than the official recharge. It should be noted that these unofficial channels or methods may have certain risks, such as account bans, personal information leaks and other problems. Therefore, I cannot provide you with specific slow charging methods.
If you need to do a King of Glory recharge, it is recommended that you do so through official channels to ensure your account security and gaming experience.
