Usually, the price of VIP chapters was inverse to the number of chapters. The higher the price, the fewer chapters there were. Therefore, if he wanted to read more chapters, he might have to pay a higher price. Mobile top-up was a payment method that allowed one to top up virtual currency on a mobile phone or tablet. Different platforms and authors might have different ways to recharge their phones, so it was necessary to understand the platform and the author's recharge method first. Some platforms support online payment and AliPay, while others support mobile or bank cards.
